    [0001] The present invention relates to an electric apparatus for the preparation of juice by pressing food.
    [0002] This type of apparatus is well known: inside a juice separation chamber, a pressing screw, typically of ogival shape, is rotated by an ad hoc electric motor, whose mechanical output is coupled to the base of the screw, while food, admitted to the top of the enclosure via an inlet chute down, are, under the action of the screw, gradually driven down and pressed against the inner face of the bottom of the speaker. The juice is collected for consumption by the user, while, separately, the pressed residues of the food are evacuated. The interest of this type of device is to obtain quality juices, greatly preserving their taste and organoleptic properties. Examples of this type of apparatus are provided, inter alia, in EP 2 326 220.
    [0003] One of the technical limitations of this type of device is the maximum size of food that can be squeezed. Indeed, for the press screw can "catch" these foods and start to drive them down to press them, it is necessary for a given screw diameter, these foods are sufficiently small, the maximum size of these food typically being smaller than the largest radius of the press screw. The user is very often obliged to cut food before admitting them into the device. For example, admission of an entire apple is impossible. To circumvent this difficulty, EP 2 326 220 has, by the embodiments of its FIGS. 1 to 5, proposed to arrange, between the outlet of the intake trough and a lower part of pressing of the screw, a food fragmentation, which consists of a cutting edge or a sharp blade and which is carried by an upper part of the screw: by the rotation of the screw, this cutting edge or this blade sweeps the outlet of the chute, if although the food coming out of the chute is cut into two slices. The implementation of such a cutting of food however poses practical difficulties. Indeed, to effectively cut a food, especially of shape close to a sphere and / or having a certain superficial hardness, such as an apple, it is necessary to hold the food in position when the cutting edge or the cutting blade is applied to this food: in EP 2 326 220, this holding in position is achieved by a rotational locking member provided in the chute, and by a push that the user must push into the chute and keep pressed against the food to prevent it from rising in the chute when applying the edge of 3021514 2 cutting or cutting blade on the food. This blocking member and this pusher, essential for the operation of the apparatus of EP 2 326 220, are binding in use. Moreover, the fact that the food is broken up into two clearly cut slices, the larger of these two slices may have a size always too large, to be "caught" by the press screw, with the potential disadvantage of being stuck at the top of the screw, in particular when the food is of shape close to a sphere and / or has a certain surface hardness, such as an apple. The object of the present invention is to provide an apparatus of the type described above, whose fragmentation of food before their pressing is improved, in particular being more effective, as well as less restrictive for the user. To this end, the subject of the invention is an electric apparatus for the preparation of juice by pressing food, comprising: a chute for feeding food downwards, which chute defines geometrically a sphere inscribed able to pass freely by the chute; - A food processing screw at the outlet of the chute, which screw: - is centered on an axis, - is coupled to an electric motor driving the screw in rotation about itself about the axis, 20 - includes an upper portion which is provided with means for scavenging the outlet of the chute, adapted to act on the food coming out of the chute to fragment it, and - includes a lower part which is designed to drive down and squeeze the fragments feed from the upper part of the screw; and 25 - an enclosure for receiving the screw, which enclosure: - is substantially centered on the axis, - includes an upper part, which is connected to the outlet of the chute to receive the food coming out of the chute and which surrounds the upper part of the screw, and - includes a lower part, which surrounds the lower part of the screw and which is designed to separate the juice from the food fragments when they are pressed by the lower part of the screw; characterized in that the upper part of the enclosure is internally provided with food blocking means adapted to block the rotation of food when the latter are in contact with the scanning means, so that, at the outlet of the chute, said inscribed sphere is movable inside this upper part of the chamber, to a position of fragmentation, in which: - by forming a first contact zone between the inscribed sphere and the blocking means , the locking means oppose the rolling of the sphere inscribed in the direction of rotation of the screw against the inner face of the upper part of the enclosure, 5 - by forming a second contact zone between the sphere inscribed and the locking means, the locking means oppose the rolling of the sphere inscribed in the opposite direction to the rotation of the screw against the inner face of the upper part of the enclosure, this second zone of co ntact being formed in a half of the inscribed sphere, which is turned away from the axis and which is delimited by a diametral plane of the inscribed sphere, both substantially parallel to the axis and passing through the first contact zone, and - by forming a third contact zone between the inscribed sphere and the scanning means, the scanning means crush the sphere inscribed in the direction of rotation of the screw, this third contact zone being formed in half of the inscribed sphere, opposite to that in which the second contact zone is formed. One of the ideas underlying the invention is to arrange the upper part of the receiving chamber of the press screw, to keep in place the "big" foods when they are in contact with the scanning means intended to fragment them. For this purpose, the invention provides that the inscribed sphere defined by the intake trough, which, geometrically, substantially corresponds to the largest pseudo-spherical food permissible in the trough, is movable from the trough without blocking the trough. inside the upper part of the enclosure, to a so-called fragmentation position, in which, without the intervention of the user, specific blocking means carried by the inner face of the upper part of the enclosure, maintain in position this inscribed sphere, while scanning means, carried by the upper part of the screw, can apply to this inscribed sphere a crushing stress. The locking means are designed both to prevent the inscribed sphere from rolling against the inner face of the upper part of the enclosure in the direction of rotation of the screw, forming, so to speak, a stop anti-roll for the inscribed sphere, and to prevent the inscribed sphere from rolling in opposite directions, forming, as it were, an anti-escape stop for that inscribed sphere. The inscribed sphere thus being firmly held in position by the locking means, which act on a portion of the inscribed sphere substantially corresponding to its vertical half turned away from the screw, the invention provides that the scanning means can act effectively on the remainder of the inscribed sphere, corresponding substantially to its other vertical half, crushing it. Thus, when the user introduces into the chute a large food, that is to say a food whose shape is close to that of the aforementioned sphere, this food moves without blocking, especially under the effect of its own weight, in the chute and then in the upper part of the enclosure, until it occupies the fragmentation position, in which it is crushed until shearing rupture in a substantially vertical and median plane of the feed . Of course, by the very nature of the food, the breaking of the food, resulting from its crushing, leads to the formation of two or more food fragments, of small sizes and having irregular shapes, which are easily and quickly "caught" by the lower part of the screw for their pressing. Thanks to the invention, for a given press screw diameter, large foodstuffs, such as whole apples, can be admitted into the apparatus for their pressing, which admission can advantageously be carried out in the axis of the screw, by centering, on this axis, at least the outlet of the chute, or even the entire chute, to then allow a maximum diametral dimensioning for the sphere listed above. According to additional advantageous features of the apparatus according to the invention, taken separately or in any technically possible combination: the third contact zone is located, in the direction of the axis, at a level which is higher; than that of the first and second contact areas; the locking means comprise, or even consist of, ribs projecting from the inner face of the upper part of the enclosure, a first rib of which and a second rib of them cooperate by contact with the sphere inscribed to form respectively the first contact zone and the second contact zone when the inscribed sphere is in the fragmentation position, said second rib immediately preceding said first rib in the direction of rotation of the screw; - four ribs which are regularly distributed around the axis; The locking means are also adapted to guide down the food they block in rotation; - The ribs are shaped in helical portions centered on the axis, which are wound down in the direction of rotation of the screw; the locking means, in particular their ribs, extend in the lower part of the enclosure to block the rotation of the food fragments when the latter are pressed by the lower part of the screw; - The inner face of the upper part of the enclosure defines a concave surface, from which the locking means are projecting and which is centrally toric on the axis; The scanning means comprise, or even consist of, an edge of the upper part of the screw, which is shaped to crush the food; The edge of the scanning means is turned towards the axis and extends downwards by being helically wound around the axis; - The output of the chute, or the entire chute, is internally centered on the axis; 5 - an upper end of the upper part of the screw forms a ring, which is centered on the axis, from which the scanning means extend downwards, through which the outlet of the chute is connected to the upper part of the enclosure so as to pass freely said inscribed sphere, and which is provided with connection means to the electric motor for driving the screw in rotation.
    [0004] The invention will be better understood on reading the following description, given solely by way of example and with reference to the drawings, in which: FIG. 1 is a perspective view of a device in accordance with FIG. invention; Figure 2 is an elevational view of the apparatus of Figure 1; Figures 3 and 4 are sections along the respective lines and IV-IV of Figure 2; - Figure 5 is a section along the line of Figure 2, showing only one of the components of the apparatus; Figure 6 is an elevational view showing only one other component of the apparatus; FIGS. 7 to 9 are a perspective view of the apparatus, partly in section, these three views respectively illustrating three different positions of a sphere admitted into the apparatus; - Figure 10 is a view similar to Figure 3, considered with the sphere of Figure 9; Fig. 11 is an elevational view of the component shown in Fig. 6, viewed with the sphere of Fig. 9; and - Figures 12 and 13 are views similar to Figure 10, schematically illustrating respectively two successive times of fragmentation of a food in the apparatus.
    [0005] In Figures 1 to 13 there is shown an apparatus 1 for preparing juices from foods, especially fruits and vegetables, by pressing these foods. The apparatus 1 comprises a screw 10 for treating food, in particular for pressing these foods, which is shown alone in FIGS. 6 and 11 and which is visible, within the appliance 1, in FIGS. , 7 to 10, 12 and 13. This screw 10 defines a central axis XX around which the screw is, in the device 1, drivable in rotation on itself and in a predetermined direction of rotation, as indicated by the arrow R 3021514 6 in the figures. In practice, when the apparatus 1 is used, the apparatus rests on a table or, more generally, a substantially horizontal work plane, so that the axis XX is vertical or substantially vertical: under these conditions, for convenience, the present document is oriented with respect to the axis XX, the terms "up" and "upper" corresponding to a direction which, in the axis XX, is turned upwards, that is to say at the Opposite of the working plane on which the apparatus rests 1. The terms "lower" and "lower" correspond to an axial direction of opposite direction. In the embodiment considered in the figures, the screw 10 includes, successively in the direction of the axis XX, both: - an upper end 11, which has an overall ring shape, centered on the XX axis and uninterrupted current all around this axis XX, - an upper portion 12, which has an overall helical shape, wrapping substantially around the axis XX and extending downwardly from the upper end 11, - a lower part 13, which has a generally frustoconical shape, centered on the axis XX and converging downwards, and - a low end 14, which has an overall shape of cone point, centered on the XX axis and inscribed in the downward extension of the lower part 13. Other characteristics of the screw 10 and its parts 11 to 14 will be described later, in connection with other components of the device 1.
    [0006] The apparatus 1 further comprises an enclosure 20 inside which the screw 10 is received so as to be rotated about itself about the axis XX with respect to this enclosure 20. In practice, the enclosure 20 is fixed relative to the work plane on which the device 1 when the latter is used. Furthermore, in a manner not shown in detail in the figures, this enclosure 20 is, within the apparatus 1, potentially integral with an external frame of this apparatus, this aspect not being limiting of the present invention. . The enclosure 20 is centered on the X-X axis, in the sense that it delimits an internal volume, which, as clearly visible in FIGS. 3, 4 and 7, internally receives the screw 10 in a substantially coaxial manner.
    [0007] In the embodiment considered in the figures, the enclosure 20 comprises, successively in the direction of the axis XX, both: - an upper end 21, which surrounds the upper end 11 of the screw 10, current all around the outside of this end 11 of the screw and extending axially radially opposite this end 11 of the screw, and which receives the end 11 of the screw 10 in a substantially complementary manner, centering thus the enclosure 20 on the axis XX, 3021514 7 - an upper part 22, which surrounds the upper part 12 of the screw 10, running all around the outside of this part 12 of the screw and extending axially radially facing this portion 12 of the screw, and the bulk of the inner face 22A is radially spaced from the upper portion 12 of the screw 10, 5 - a lower portion 23, which surrounds the lower portion 13 of the screw 10, running all around the outside of this portion 13 of the screw and extending ax in radial relation of this portion 13 of the screw, and which is complementary to the lower part 13 of the screw 10, thereby having an inner face 23A which is conical, centered on the axis XX and converging downwards, and a low end 24, which surrounds the lower end 14 of the screw 10, by running all around the outside of this end 14 of the screw and extending axially at least radially from this end 14 the screw, or, as here, lower than this end 14 of the screw, and which has a generally tubular shape, centered on the axis XX and open at its two opposite axial ends.
    [0008] Other characteristics of the enclosure 20 and its parts 21 to 24 will be described later, in connection with the rest of the apparatus 1. The apparatus 1 also comprises a chute 30 through which are admitted foods which are to be treated inside the enclosure 20 by the screw 10. In the embodiment considered here, the chute 30 has a generally tubular shape, centered on the axis XX. In practice, other embodiments are possible for the chute 30, as long as the downward opening of this chute is connected to the upper part 22 of the enclosure 20 so that the feed introduced into the chute reaches this part. high of the speaker. In all cases, the chute 30 geometrically defines a registered sphere 2, 25 which is drawn in FIGS. 7 to 11 and which is the largest sphere that can be introduced into the chute 30 and reach the outlet thereof without to be locked in the chute. In other words, as clearly visible in FIG. 7, the inscribed sphere 2 is a fictitious three-dimensional geometric object, consisting of the "largest ball" which can reach without blocking, that is to say without interference of complete stop of the movement, the outlet of the trough 30 from outside the apparatus 1 via the inside of the chute. It is understood that this sphere inscribed 2 simulates the largest spherical food that can be admitted whole in the apparatus 1 in order to obtain the juice. By way of non-limiting example, the internal diameter of the chute 30 is about 80 mm, which is to say that the registered sphere 2 has a diameter of the same value.
    [0009] In practice, the chute 30 is fixed within the apparatus 1, being secured, directly or indirectly, to the enclosure 20, the outlet towards the bottom of the chute 3021514 8 overhanging the screw 10. embodiment considered in the figures, the lower end of the chute 30 is secured to the upper end 21 of the enclosure 20 by means of a fixed connecting piece 40 which belongs for example to the aforementioned frame of 1. As a variant not shown, the part 40 is made in the form of an upward extension of the upper end 21 of the enclosure 20 and / or an extension downwards of the lower end of the trough 30. At the axial level of the connection region between the enclosure 20 and the trough 30, here inside the assembly part 40, the upper end 11 of the screw 10 is provided with means 110 for connecting to an electric motor, not shown, for driving the 10 screw 10 rotated about the axis X-X, the electric motor being for example housed in the aforementioned frame of the apparatus 1. In the figures, the connecting means 110 are shown only schematically. In practice, these connecting means 110 may have very different shapes, as long as these connecting means provide at least a portion of the coupling between the aforementioned electric motor and the upper end 11 of the screw 15 so as to drive this screw in rotation about itself around the axis XX. By way of nonlimiting example, these connecting means 110 are mechanical and consist of a ring gear, a gear, a drum, etc., more generally a rotating part, centered on the axis XX and driven in rotation on itself by a cable, a belt, etc., externally girdling this rotating part and set in motion by the above-mentioned electric motor. In all cases, it is understood that, in use, the connecting means 110 are rotatably connected to the upper end 11 of the screw 10, being secured to this upper end of the screw by any appropriate means, advantageously so removable to allow, when the device 1 is not in use, disassembly between the connecting means 110 and the screw 10 and thus facilitate their cleaning. Whatever the embodiment of the connecting means 110, note that their presence at the high end 11 of the screw 10 substantially stiffens the end 11 of the screw, which is to say that these connecting means 110 firmly fix in position the axis XX within the apparatus 1, taking again the radial forces applied to the screw 10 during its rotation, in particular applied to its upper end 11 and its upper part 12, without these radial forces are taken up, at least substantially, at the centering interface between the upper end 11 of the screw 10 and the upper end 21 of the enclosure 20. Given the presence of the connecting means 110 at the end 11 of the screw, the outlet towards the bottom of the chute 30 is connected to the internal volume of the upper part 22 of the enclosure 20 by the inside of the ring formed by the upper end 11. Thus, the 3021514 9 food coming out of the chute 30 rejoignen t, via the upper end 11 of the screw 10, surrounded by the upper end 21 of the enclosure 20, the upper part 22 of the enclosure 20 to be treated by the upper part 12 of the screw 10. The inner diameter of the ring formed by the upper end 11 of the screw 10 is at least equal to or slightly greater than the diameter of the inscribed sphere 2 so that this sphere passes freely, that is to say without interference blocking, the outlet of the chute 30 inside the upper portion 22 of the enclosure 20, via the inside of the upper end 11 of the screw, as shown in Figure 8. At the axial level of upper portions 12 and 22 of the screw 10 and the enclosure 20, it is intended to treat the food for subsequent pressing at the lower parts 13 and 23 of the screw and the enclosure. For this purpose, in the embodiment considered in the figures, the upper part 12 of the screw 10 delimits an upwardly facing surface 12A, to guide the food from the inside of the upper end 11 of the screw until outside of the lower part 13 15 of the screw: as clearly visible in FIG. 6, this guide surface 12A is helical, by wrapping substantially around the axis XX and connecting the inner face of the ring formed by the upper end 11 to the outer face of the larger diameter of the conical lower portion 13. As shown in Figs 8, 9 and 11, the guide surface 12A is provided, in particular by its inclination, for leaving the inscribed sphere 2 20 movable downwards from the inside of the upper end 11 of the screw, and following a substantially helical global trajectory resulting from the notional rolling and / or sliding of this sphere 2 on the guide surface 12A in the inter In addition, the upper part 12 of the screw 10 is provided with means 120 for scanning the outlet of the chute 30, designed for, inside the upper part of the upper part of the enclosure. 22 of the enclosure, fragment food coming out of the chute 30, before the food fragments join the lower part 23 of the enclosure 20 to be pressed by the lower part 13 of the screw 10. In the example embodiment considered in the figures, the scanning means 120 consist of a crushing edge 121 of food, delimited by the upper portion 12 of the screw 10. This crushing edge 121 extends downwards from the ring formed by the upper end 11 of the screw 10, being turned towards the axis XX and winding helically around this axis, to the lower part 13 of the screw 10 as clearly visible in the figures 6 and 7. For reasons that will appear later, the crushing edge121 need not be sharp or sharp in the sense that, when it acts on the food to break it up, it is not designed to slice it by the net division of the feed material on either side of the ridge, but this Edge 121 is designed, by its shape, to crush the food until breakage of the material of the latter by tearing and / or tearing. So that the action of the scanning means 120 on the food is preforming for fragmentation, the upper part 22 of the enclosure 20 is internally provided with blocking means 220 which block the rotation when the food is at contact of the scanning means 120. In the embodiment considered in the figures, these locking means 220 consist of four ribs 221, 222, 223 and 224 which, as can be seen in FIGS. 3 and 4, are individually identical to each other. to each other, are distributed uniformly about the axis XX and each extend projecting towards the axis XX from the inner face 22A of the upper part 22 of the enclosure 20. These ribs 221 to 224 constitute the portions of the inner face 22A of the upper part 22 of the enclosure 20, which are the closest radially to the axis XX. The crushing edge 121 and the ribs 221 to 224, more generally the scanning means 120 and the locking means 220, are arranged and dimensioned in relation to the inscribed sphere 2, in the sense that, inside of the upper part 22 of the enclosure 20, this inscribed sphere 2 is movable to a fragmentation position, imposed on the sphere inscribed by these scanning means 120 and these locking means 220, this displacement of the registered sphere 2 up to this fragmentation position being advantageously guided inside the upper part 22 of the enclosure 20 by the guide surface 20 as shown above. More precisely, when the inscribed sphere 2 occupies the abovementioned fragmentation position, which is represented in FIGS. 9 to 11, several contact zones are formed between, on the one hand, the inscribed sphere and, on the other hand, the means 120 and the blocking means 220, namely: a first zone C1 of contact between the inscribed sphere 2 and a first of the ribs 221 to 224, in this case the rib 221 in FIG. 10, so that by acting on the sphere inscribed by this contact zone C1, the rib 221 opposes the rolling of the sphere inscribed in the direction of rotation R of the screw 10 against the inner face 22A of the upper part 22 of the enclosure 20, a second zone C2 of contact between the inscribed sphere 2 and a second rib immediately preceding the first aforementioned rib in the direction of rotation R of the screw 10, in this case the rib 222 in FIG. , so that by acting on the sphere inscribed by this second contact zone C2, this second rib is opposed to the rolling of the sphere inscribed in the opposite direction to the rotation R of the screw against the inner face 22A of the upper part 22 of the enclosure 20, the second contact zone C2 being formed in the half of the inscribed sphere, which is turned away from the axis XX and which is delimited by a diametral plane, denoted 2A in FIG. 10, 3021514 11 of the registered sphere , both parallel to the axis XX and passing through the first contact zone C1, and - a third zone C3 of contact between the inscribed sphere 2 and the crushing edge 121 of the screw 10, so that, by acting on the sphere inscribed by this third contact zone C3 during the rotation of the screw, the crushing edge 121 crushes the sphere inscribed in the direction of rotation R of the screw, this contact zone C3 being formed in half of the inscribed sphere, opposite to that in which is formed the second contact zone C2. In the embodiment considered in the figures, it will be noted that in the section plane of FIG. 10 the contact areas C1 and C2 are indicated, while the third contact zone C3 is not visible: this results from the fact that the first and second contact areas C1 and C2 are located substantially at the same axial level, namely that of the section plane of Figure 10, while the contact area C3 is located at a different axial level, in this case higher than the axial level of the section plane of FIG. 10. Whether at different axial levels or not, the three contact zones C1, C2 and C3 make it possible, during the rotation of the 10, to apply shear stresses to the inscribed sphere 2 substantially in its diametral plane 2A: at the contact zone C1, the rib 221 forms an anti-rolling abutment in the direction of rotation R for the sphere inscribed 2, so that at the zo contact C3, the crushing edge 121 is able to press the half, facing the axis XX, of the sphere 2 outside the diametral plane 2A of the latter, while preventing the sphere inscribed d escape the action of the crushing edge 121 away from the axis XX and / or upwardly, due to its blocking, at the contact zone C2, 25 by the rib 222 which thus forms an anti-escape stop for the inscribed sphere. Of course, it is understood that the fragmentation configuration, which has just been described with reference to FIGS. 9 to 11, constitutes only one of the four possible fragmentation positions inside the upper part 22 of the enclosure 20, evenly distributed about the axis XX, in connection with the distribution of the four ribs 221 to 224 around this axis. Furthermore, because the ribs 221 to 224 constitute the portions of the inner face 22A of the upper portion 22 of the enclosure 20 radially closest to the axis XX, an advantageous option is that, as clearly visible in FIGS. 3 and 6, the upper part 12 of the screw 10 includes, in its outer periphery, a wall 122, which has an overall half-tube shape, centered on the axis XX, which borders the outer periphery of the guide surface 12A and whose outer face 122A is dimensioned 3021514 12 to be substantially tangential to the ribs 221 to 224, with the interposition of a functional clearance not to induce wear: this arrangement between the ribs 221 to 224 and the upper portion 12 of the screw 10 induces a scraping effect of the face 122A to prevent the accumulation of food residues.
    [0010] According to an advantageous embodiment, the inner face 22A of the upper part 22 of the enclosure 20 is constituted, apart from its portions occupied by the ribs 221 to 224, as well as outside its connection zone with the the upper end 21 of the enclosure and its zone of connection with the lower part 23 of the enclosure, a concave surface 22B, from which the ribs 221 to 224 are protruding and which is centrally toric on the XX axis: the toric conformation of this concave surface 22B makes it possible, in its deepest part, to accentuate the projecting extent of the ribs 221 to 224 and thus to reinforce their effect of blocking food, while conferring on the face inside the enclosure 20 a non-angular profile at least over the axial height of its upper part 22.
    [0011] Also as an advantageous option, each of the ribs 221 to 224 is shaped as a helical portion centered on the axis XX, which is wound downward in the direction of rotation of the screw 10, as clearly visible. in FIG. 5: In this way, in addition to their food blocking function, the ribs 221 to 224 have a feed guiding function downwardly against the inner face 22A of the upper portion 22 of the enclosure 20 With regard to the low, conical and complementary parts 13 and 23 of the screw 10 and the enclosure 20, it will be noted that the lower part 13 of the screw is externally provided with threads 130, which are wound towards the from the guide surface 12A of the upper portion 12 of the screw 10, more generally from the connection zone between this guide surface 12A and the outer face of the screw, to the lower end 14 of the screw , advantageously by extending on the outer face of this extr 14. These threads 130 are designed for, during the rotation R of the screw 10, to drive downwards, inside the lower part 23 of the enclosure 20, the food fragments which come from the upper part 22 of the enclosure and which enter the lower part 23 of the enclosure, via a passage which, upwards, is delimited by the crushing edge 121 and which, downwards, is delimited by the guide surface 12A, more generally by the connection zone between this guide surface 12A and the outer face of the screw. In their upper part, the nets 130 "catch" the fragments of food that have just crossed the aforementioned passage, this catch being facilitated by providing, as advantageous options, visible in FIGS. 6 and 11, that: 3021514 13 - At least in the lower region, the upper part 12 of the screw defines a helical surface 12B turned downwards, for, during the rotation R of the screw, push food fragments downwards, and / or - at at least one of the threads 130 extends upwards on the outer face of the upper part 12 of the screw. After catching the food fragments, the threads 130 are designed, always when the screw 10 is rotated about the axis XX, to press these food fragments against the inner face 23A of the lower part 23 of the enclosure 20, as these food fragments are driven downward within the lower part 23 of the enclosure, more precisely between the inner face 23A of this lower part 23 and the face outer portion of the lower portion 13 of the screw. The lower part 23 of the enclosure 20 is provided with through orifices 230 for sieving the foodstuffs, by which the juice resulting from the pressing of the food fragments passes from the inside to the outside of the lower part 23 of the 20. More generally, it will be understood that the lower part 23 of the enclosure 20 is designed to separate the juice from the food fragments when the latter are pressed by the lower part 13 of the screw 10, this juice passing through the outside of the lower part 23 of the enclosure 20, while the pressed food residues remain inside this lower part 23 of the enclosure. The conical complementary shapes of the lower part 13 of the screw 10 and of the lower part 23 of the enclosure 20 make, on the one hand, concentric the radial forces applied to the lower part 13 of the screw during the pressing of the fed by this screw driven in rotation, the sum of these radial forces being substantially zero, which limits any tendency of the screw to be misaligned inside the enclosure 20, and, on the other hand, reinforces the mechanical resistance of the lower part 23 of the enclosure 20 vis-à-vis the radial forces 25 applied to this lower part, partially distributing the corresponding stresses upwards and downwards, which avoids local over-stress. In the continuation of the foregoing considerations, an advantageous embodiment consists in producing the lower part 23 of the enclosure 20 in one piece of metal, typically in a perforated plate of the orifices 230. This being, in a variant, the part 30 bass 23 of the enclosure can be made of several parts, metal or another material. As an advantageous option, in particular to improve the pressing of the food fragments, the ribs 221 to 224 of the upper part 22 of the enclosure 20 extend into the lower part 23 of the enclosure: as clearly visible in FIG. 4, these downward extensions of the ribs 221 to 224 allow, in the lower portion 23 of the enclosure 20, to block the rotation of the food fragments when the latter are driven by the nets 130 of FIG. the lower part 13 of the screw 10. At the axial end of the lower end 24 of the enclosure 20, the interior of this end 24 of the enclosure channels, downwards and centrally on the axis XX, the pressed food residues from the inside of the lower part 23 of the enclosure, the downward drive of these residues being advantageously reinforced by the cone tip forming the lower end 14 of the screw 10 when the latter is rotated about the axis XX . In other words, the lower end 24 of the enclosure 20 constitutes an outlet for evacuating the pressing residues outside the enclosure 20. This evacuation of the residues taking place in the axis XX, it is particularly effective, especially without inducing resistance to the flow of residues from the lower part 23 of the chamber 20, to exit the enclosure. In the continuation of the foregoing considerations, it will be noted that this discharge outlet, formed by the lower end 24 of the enclosure 20, does not interfere internally with any of the arrangements of the apparatus 1 which make it possible to drive the screw 10 rotating: indeed, as explained above, the screw 10 is rotated through the connecting means 110 provided at the upper end 11 of the screw 10, while the cone tip forming the The bottom end 14 of the screw is free and received without contact within the discharge outlet formed by the end 24 of the enclosure 20. As an option, not shown in the figures, the output of FIG. evacuation formed by the lower end 24 of the enclosure 20 is provided with means, known per se, for adjusting the resistance to flow of the pressing residues through this discharge outlet: for example, such adjustment means comprise a dia diaphragm 25 partially occluding the flow section through the discharge outlet, the extent of action of this diaphragm being adjustable, or these adjustment means comprise a partial closing valve of the outlet to the bottom of the discharge outlet, the position of this valve being adjustable by means of a slave mechanism. Externally, the lower end 24 of the enclosure 20 is surrounded by a recovery tank 30 or, more generally, by means 50 for collecting the juice coming from the outside of the lower part 23 of the enclosure 20. An example of use of the apparatus 1 will now be described, and more specifically with reference to FIGS. 7 to 12, considering that a whole apple P whose shape and dimensions are substantially identical to those of the invention is introduced into the apparatus 1. those of the listed sphere 2 considered above.
    [0012] Thus, initially, while the apparatus 1 is in use, in particular with its screw 10 rotated on itself about the axis XX by the aforesaid drive motor, the apple P is admitted The apple P goes down inside this trough, under the effect of its own weight, as shown in FIG. 7. After having reached the upper part 22 of the trough enclosure 20 passing without blocking from the inside of the upper end 11 of the screw 10, the apple P rolls and / or slides down against the guide surface 12A, until coming into contact with the inner face 22A of the upper part 22 of the enclosure, as represented in FIGS. 9 to 11: by maintaining the rotation drive of the screw 10, the apple P is found in one of the four fragmentation positions, described above, for example the fragmentation position of Figures 9 to 11. While the apple P is firmly locked by cooperation between its outer half and two of the ribs 221 to 224, in this case the ribs 221 and 222 in Figures 9 to 11, the edge 121 of the screw 10 crushes the inner half 15 of the apple P, in the direction of rotation R of the screw. In view of the nature of the material constituting the apple P, this crushing edge 121 tends to sink into the apple P, while also pushing into this apple the rib 221, as illustrated in FIG. shown in FIG. 13, the apple P breaks, by primer in a diametral plane between its two aforementioned halves and then by tearing of its material, forming two or more fragments which have irregular shapes, related to tearing and / or or distortions of the apple material. The fragment or pieces turned away from the axis XX are introduced into the lower part 23 of the enclosure 20, via the passage delimited between the crushing edge 121 and the guide surface 12A: this or these Fragments are then progressively driven and pressed at the interface between the conical and complementary lower parts 13 and 23 of the screw 10 and the enclosure 20. It will be noted that the apple fragments are particularly easy to "catch" by the threads 130 of the screw 10 when the rupture fragmentation of the apple P is initiated in a substantially diametral plane of the apple, which is inclined relative to the vertical, by providing the axial offset of the contact zone C3 relative to to contact areas C1 and C2. The juice resulting from the pressing of this or these fragments is recovered outside the chamber 20 by the collection means 50, while the pressing residues are discharged in the axis XX by the lower end 24 of the pregnant.
    [0013] Various arrangements and variants of apparatus 1 described so far are furthermore possible. By way of example, rather than driving the screw 10 in rotation by its high end 11, this screw can be driven by its low end, then giving up the pressure residues in the axis XX and, if necessary, also giving up the conical shape for the lower part 13 of the screw.
