    SPINDER MACHINE TO PRODUCE SOY MILK WITH GRINDING FUNCTION
    FIELD OF THE INVENTION [001] The present invention describes a squeezing machine for producing soy milk, more particularly a squeezing machine for producing soy milk with a grinding function.
    STATE OF THE TECHNIQUE [002] Food processors, such as soy milk machines, extractors / squeezers, blenders, etc., are an important category of household items. In recent decades, such food processors have become popular on the world market and appreciated by users in China, due to their convenience, speed and compatibility with Chinese food. The main technologies related to conventional machines to produce soy milk, juicers, blenders and other automatic food processors are of three main types, as described below:
    1. The feed material is broken by high speed rotation of metal blades. Conventional machines for producing soy milk and food processors mostly belong to this type.
    2. The feed material is processed into small filaments or pieces by the relative movement between the
    Petition 870180165801, of 12/20/2018, p. 16/44
    2/24 feed material and a metal scraper that has several cutting holes (serving as small scraping blades) on the surface. The juice and waste are then separated by centrifugal force. An example is the scraper type juicer.
    3. The feed material is pushed into a small chamber by a screw rod and extruded through a fine metal filter positioned at the opposite end of the chamber. Alternatively, the feed material can be cut into small pieces by a set of blades that move relative to each other to cut the feed material into small pieces and extract the juice. Examples are the screw-type juicer and the meat grinder.
    [003] The food processor of the first and second types has the following disadvantages:
    1. Metal blades can become rusty and blunt after repeated use.
    2. The processed food material can stick to the metal sheets due to the heat generated in the metal sheets during operation, which makes them difficult to clean. This is particularly problematic for the machine to produce soy milk with a heater since the feed material adheres easily to the metal sheets when being heated.
    3. Metal sheets can become contaminated and produce abnormal odors due to the growth of
    Petition 870180165801, of 12/20/2018, p. 17/44
    3/24 bacteria in the micro-pores on the surface of the metal sheets, which can affect the taste of the processed food material, affect the color of the food due to the chemical reaction of contact with the food material, such as fruit, and even even harmful to health, due to the small amount of heavy metal elements released from the metal blades during mixing and grinding operations.
    [004] Conventional automatic soy milk machines, as described above, do not work in exactly the same traditional way of producing soy milk. In the traditional way, soybeans are ground by hand using a stone mill. The stone mill can be of various types, such as wet mill, dry mill, oil mill or paste mill, etc. Among them, the wet mill is a traditional tool specifically for producing soy milk. The soybeans to be processed are placed between a pair of grinding plates (including the upper plate 36 and a lower plate 37, see Fig. 1.) after immersion in water. Both opposite surfaces of the upper and lower plates 36 and 37 have cutter teeth 38 in the peripheral regions along radial directions. The length of the cutter teeth 38 of the upper plate 36 is less than the length of the cutter teeth of the lower plate 36. The cutter teeth 38 can have an arrangement of eight divisions each with eight teeth (as shown in Fig. 1) . Alternatively, the milling teeth 38 can have another arrangement, such as ten divisions, each with four teeth or ten divisions each with six teeth, depending on the
    Petition 870180165801, of 12/20/2018, p. 18/44
    4/24 need for the specific circumstance. Water is added through the feed inlet, while the grinding plates rotate, and the soybeans are pressed by a pair of grinding plates and crushed by the milling teeth due to the relative movement of the two milling plates. The process then produces soy milk. During such a grinding process, soybeans are subjected to a variety of actions such as crushing, pressing, mixing, friction, twisting and grinding, which makes soy milk rich in flavor and good taste.
    [005] It was found that the low speed of rotation of the stone mill is directly related to the richness in flavor of soy milk produced in a traditional way. The traditional hand-operated stone mill operates at a rotation speed of 4-7 revolutions per minute. During this process at low speed, the soy milk protein is sufficiently exposed to air and is thus fully oxidized. The slower the rotation speed, the richer the flavor of soy milk. That is why soy milk made by the traditional stone mill has a more enriched aroma and flavor. In addition, soy milk is filtered with a cotton cloth and is therefore light and smooth, with a great flavor.
    [006] In comparison, most conventional machines for producing existing soy milk employ a mixing process of the first type mentioned above, in which the soy beans are broken or broken into small pieces, mixed and heated at the same time. In this way, the traditional milling process was replaced by a spraying process
    Petition 870180165801, of 12/20/2018, p. 19/44
    5/24 simple and crushing in machines to produce soy milk.
    Consequently, a large amount of residual grain powder remains in soy milk. In addition, the speed of rotation of the blades of the machine to produce soy milk (more than 10,000 rpm) is much greater than the speed of rotation of a traditional stone mill, which can destroy some of the nutrients in soy milk and reduce the rate of extraction of nutrients from the grains. The soy milk manufactured by the machine to produce soy milk is drastically different from the soy milk produced by the traditional stone mill in terms of aroma, taste and level of nutrients. In short, the traditional stone mill produces better soy milk. In addition, the machine for producing soy milk of the first type does not have a separation step to separate soy milk from waste. The resulting soy milk contains both milk and waste, which not only affects the taste, but also affects the human body's absorption of nutrient ingredients. In addition, conventional machines for producing soy milk vibrate due to the high speed of rotation, which in turn generates unpleasant noises.
    [007] The machine for producing soy milk of the third type is rare, but the Chinese Patent 200780001269.X called Juicer (Squeezer) reveals a squeezing machine to produce from
    soy milk such type. As shown in the Figures 1 and 2, the squeezing machine includes a rod in screw 200 it is a mesh container 300, installed at vertical, in form
    concentric. The height of the thread on the surface of the screw rods 200 decreases from top to bottom. There is a
    Petition 870180165801, of 12/20/2018, p. 20/44
    6/24 grinding arranged on the inner surface of the mesh container 300. The feed material enters the gap between the mesh container and the threads of the screw stem above. The feed material located in the gap is then squeezed and crushed by the rotation of the screw rod and the juice generated during the process flows through the mesh container through the mesh filters arranged in the upper and lower positions (mesh 320 for separation and mesh 330 for compression) and is discharged through the juice outlet, and the waste is discharged through the residual outlet 570.
    [008] The juicer described above has the following disadvantages: the screw shank is shaped like a loom hook with smaller ends and a larger medium section. The gap between the screw rod and the mesh container has an upper section f 1 with the guide and break functions, having a larger gap size. The middle section f2 is for spraying with a small gap, and a lower section f3 for separating the juice and waste with a slightly increased gap. The clearance in section f1 is gradually decreased from top to bottom and reaches a minimum at spray point f2. The feed material goes through the steps of guiding, breaking, spraying and eventually enters a separation zone between the juice and the residue.
    [009] The juicer processes the feed material by compression and grinding, unlike the grinding process in conventional grinding performed manually. Therefore, although the screw rod rotates slowly, the aroma and taste of the milk
    Petition 870180165801, of 12/20/2018, p. 21/44
    7/24 soybeans are still drastically worse than soy milk produced by the traditional stone mill approach, due to the lack of the grinding process. In addition, since the feed material is not ground, the feed material has larger particle sizes, which can easily stick to the filter mesh and need to be brushed into the milk by the rotating brush 400. Otherwise, the filter mesh will be clogged, affecting the yield of soy milk. This will also increase the powder content of soy milk and affect the texture and smoothness of soy milk.
    [0010] Another relevant precedence is the patent application US2009049998 - Juice Extractor, published on 02/26/2009 that describes a juice extractor capable of extracting the juice of vegetables, fruits or soy milk from soy beans, comprising a carcass provided with a waste outlet channel (bagasse) and a juice outlet channel, a screw having an upper axis inserted in a housing in the lid and a lower axis with a plurality of screw spirals formed on its periphery and a sieve drum to extract the juice towards the juice outlet channel and a rotating brush associated with a support mounted between the housing and said net drum. Various nutrients and intrinsic flavor contained in vegetables or fruits are conserved, using a screw of very low speed in a way of squeezing. Furthermore, since the housing that accommodates the screw is fixed vertically to an upper part of a drive unit, the material is automatically moved downwards without being pressed, and the
    Petition 870180165801, of 12/20/2018, p. 22/44
    8/24 waste is discharged while the materials placed in the inlet passage are crushed and crushed.
    [0011] It is also worth mentioning the patent document CN2542178 Multi-functional squeezing and soya-bean milk grinding mill, published on 02/04/2003, which describes a multifunctional juice extractor comprising a base 17 on which a 16 engine is installed, a drain basin 11 placed on the base and a cover plate. An upper lid 3 is associated with a funnel 2 which is provided with a partition to separate the water inlet from that of the material to be processed. The side wall of the flushing bowl 11 is provided with a flushing spout 15.
    [0012] According to the figures included in this document, the axis of the drive motor 16 projects upwards and fits into a disk 10 which, in turn, is provided with an axis 10a that crosses the wall of the drainage basin 11, a splash-proof skirt 9, the vat-shaped filter net 8 and the disc-shaped dynamic shredding plate 7. The upper face of the disk 7 is in contact with the fixed shredding plate 5, the material being routed directly to be crushed between said plates, with no further fragmentation or grinding steps.
    BRIEF DESCRIPTION OF THE INVENTION
    Petition 870180165801, of 12/20/2018, p. 23/44
    9/24 [0013] One of the objectives of the present invention is to offer a machine to produce soy milk / squeezer with a grinding function, having a simple structure to produce a juice, which retains the aroma of the food material and has a flavor smooth and soft texture, with rich nutrient contents. The machine for producing soy milk can achieve the grinding effect of a traditional stone mill and process the feed material with a combination of actions such as crushing, pressing, mixing, friction, twisting and grinding, resulting in a better juice.
    [0014] The objective of the present invention is achieved by applying the following technical solution: a machine for producing soy milk with a grinding function, comprising an upper body and a lower body, including a drive device. The upper body includes a housing, an upper cover and a rotor-stator pair installed vertically inside the housing. The rotor is inserted into the stator and includes a rotor body, threads distributed on the outer surface of the body, and a drive connection device connected to the drive device at the bottom of the body. The stator has two ring-shaped filters in both the upper and lower portions, respectively, and between the two filters there are vertical grinding plates arranged on the internal wall of the stator. The base of the housing has a juice discharge outlet and a waste discharge outlet. There are at least two threads evenly distributed over the rotor body, and there is a rotating gap between the rotor threads and the stator interior wall. The rotor body has a part
    Petition 870180165801, of 12/20/2018, p. 24/44
    Upper 10/24 of rotational symmetry with an increasing diameter from top to bottom, so that the rotary clearance between the rotor and the stator has its size gradually reduced from top to bottom. The clearance is greater in the breaking section for processing a feed material, that is, in the upper part; the clearance is medium in the spray section to further crush the feed material in the middle; and the clearance reaches its minimum size of about 1mm in the grinding section at the bottom. In addition, a section for separating the juice and the residue is located below the grinding section. With a slow rotor rotation speed inside the stator, the food material is guided, broken, pulverized, ground and separated, when moving from top to bottom in the space between the rotor and the stator. Finally, the juice is produced and discharged.
    [0015] In the present invention, the threads are evenly distributed over the rotor body, so that the rotor can rotate stably. Since the rotor operates at a low speed of less than 100 revolutions per minute, it does not vibrate, so the noise is greatly reduced. The feed material is guided, broken, pulverized, ground and separated, so that the grinding process is similar to the traditional stone mill process and can grind the feed material into finer particles and produce a juice with a rich flavor, mild taste and higher nutrient content to improve the absorption rate of the nutrient content when ingested by the human body. In addition, as the grinding process is similar to the traditional stone mill process, the resulting juice is smoother and the stator filters
    Petition 870180165801, of 12/20/2018, p. 25/44
    11/24 can be kept clean (that is, not blocked by residues) so that the yield can be preserved without using a rotating brush as used in the prior art.
    [0016] As a preferred embodiment of the present invention, the grinding gap, which is located between the middle part of the rotor and the lower part of the stator grinding plate, has a width D between 0.5 mm and 0, 8 mm and an L3 length between 10 mm and 25 mm.
    [0017] Preferably, a nano-ceramic rotor ring made of nano-ceramic materials is formed on the outer surface of the rotor in the grinding section, and a nano-ceramic rotor ring made of nano-ceramic materials is formed correspondingly on the interior surface of the stator, so that the feed material is milled at a low speed in the grinding gap between the nano-ceramic rotor ring and the nano-ceramic stator ring. The nano-ceramic material has advantages such as the absence of micropores, high density without heavy metal elements (such as nickel and chromium), resistance to acids and bases, resistance to oxidation, no chemical reactivity with the food, without harmful precipitation and low absorption of food materials, which can make it easier to preserve the taste of food, allow easy cleaning and suppress the growth of bacteria, while still being beneficial for health when used in the long term. In addition, the hardness and wear resistance of the ceramic material is much higher than conventional metallic materials, presenting
    Petition 870180165801, of 12/20/2018, p. 26/44
    12/24 long-term stability and high recycling rate, which can effectively improve the life of the device and reduce environmental pollution when the device is disposed of.
    [0018] As an embodiment of the present invention, the rotor comprises an upper rotor, a nano-ceramic rotor ring and a lower rotor. The nano-ceramic rotor ring is located in a groove for installing the ring formed in the corner part on the upper surface of the lower part of the rotor. The upper rotor is integrally connected to the upper part of the lower rotor.
    [0019] As an embodiment of the present invention, the upper body housing has a cup shape. The top cover is placed at the top of the housing and has an entrance. The rotor has a central axis of rotation, which has an upper end held in position by means of the upper cover. The inlet passage is offset in relation to the axis of rotation, and is connected to the space between the rotor and the stator by means of the rotor threads.
    [0020] In order to prevent leakage of the juice (juice) into the connection device between the rotor and the drive device, which can induce the growth of bacteria or oxidation of the metallic components, the present invention adopts a structure waterproof at the base of the housing. Based on the principle that water always flows to a lower level, the waterproof structure adopts a shape similar to a
    Petition 870180165801, of 12/20/2018, p. 27/44
    13/24 plateau, in the central part of the base of the housing, and its flat top is at a higher level than the plane on which the bottom surface of the rotor touches the base of the housing. The table-like structure (hereinafter referred to as the table) has a central through hole to allow the drive connection device to pass through it, and a recess with a shape corresponding to the table is correspondingly created on the bottom surface of the rotor so that the table fit well into the recess. There is at least one sealing element arranged between the table and the recess. For example, the sealing member can be a sealing ring, which has a U-shaped cross section and is mounted on the inner wall of the central hole of the housing. The sealing element can also prevent the entry of juice into the space between the orifice and the connection device of the drive.
    [0021] As an additional improvement, the table has at least one additional step along the circumferential direction with a ring-shaped flange formed on the surface of the step serving as an additional waterproof structure. Correspondingly, there is a ring-shaped groove on the bottom surface of the rotor, and the flange is fixed in the groove.
    [0022] In order to further improve the impermeability, a ring-shaped guide groove is formed at the base end of the housing and a projecting guide ring is formed at the end of the bottom surface of the rotor, and the guide ring is inserted into the guide slot. The guide groove and guide ring are a means of
    Petition 870180165801, of 12/20/2018, p. 28/44
    14/24 outer sealing to prevent juice from entering the space between the rotor and the housing base.
    [0023] As a specific embodiment of the present invention, the clearance between the separation section between juice and rotor residue and the filter at the bottom of the stator is used to separate the juice from the residues, which is gradually increased from the top to the lower part, thus forming a structure similar to a bell mouth.
    [0024] The separation gap between the juice and the residue of the present invention has a width H between 1.0 mm and 2.0 mm (that is, the distance between the outer wall of the rotor and the inner wall of the stator) and an L4 length between 10 mm and 25 mm.
    [0025] The present invention has the following technical effects, with respect to the prior art:
    (1) The rotor has two or more threads evenly distributed over the rotor body, so that the rotor
    can rotate steadily, what reduce vibration and the noise.(2) With The adding a section grinding with clearance bottom The 1 mm (located in between the part bottom of rotor and The grinding plate stator) and a gradual
    decrease (from top to bottom) in the size of the gap between the top of the rotor and the stator, the food materials that enter the processing chamber of the
    Petition 870180165801, of 12/20/2018, p. 29/44
    The present invention not only crosses the breaking section, the spraying section, the juice / residue separation section, but also undergoes a grinding process after spraying. Such a low speed grinding process is similar to the traditional grinding of the stone mill, which processes the feed material through a combination of various actions such as grinding, pressing, mixing, friction, twisting and grinding, and can grind the materials feeding in finer particles to extract more nutrients and improve the absorption rate of these nutrients by the human body.
    (3) In addition, due to the grinding process of the present invention, the juice is smoother and the stator filters can be kept free to maintain the juice and residue yield, without the need to use the conventional rotary brush so that the present invention has a simpler structure compared to the prior art.
    (4) The optional use of nano-ceramic materials in the grinding section of the rotor and stator can improve wear resistance, facilitate cleaning and suppress the growth of bacteria and have less absorption of food material. These materials can improve the quality and durability of the product, control the release of harmful elements from the metal sheets, maintain long-term stability and offer a high recycling rate, allow easy cleaning and reduce environmental pollution when the product is discarded.
    Petition 870180165801, of 12/20/2018, p. 30/44
    16/24 (5) The present invention can extract more nutrients from the food material, improve the taste and make the nutrient content more easily absorbable by the human body. In short, the product of the present invention has greater viability, compatibility and lower manufacturing cost, being easy to use and environmentally friendly.

    DETAILED DESCRIPTION OF THE INVENTION
    First Realization
    Petition 870180165801, of 12/20/2018, p. 32/44
    18/24 [0037] As shown in figures 4 to 6, the squeezing machine for producing soy milk with a grinding function according to the present invention comprises an upper body and a lower body (not shown). The lower body includes a drive device. The upper body includes a housing 11, a cover 12 and a concentric rotor 13 and a corresponding stator
    14, installed vertically inside the housing 11. The rotor is inserted into the stator 14 and includes a rotor body 15, a protruding thread 16 on the outer surface of the body 15 and a connection device for connection to the drive device. In this embodiment, the connecting device is a rotation axis 32 located in the central part of the rotor 13. The stator 14 has ring-shaped filters both at the top and at the bottom, which are respectively a return filter for soy milk 17 and a filter for separating the juice and residues 18. Vertical grinding plates 19 and the vertical blades 33 are arranged on the inner wall between the return filter for soy milk 17 and the filter for separating the juice and residues 18. The base the housing 11 has a juice discharge outlet 20 and a waste discharge 40. In this embodiment, there are three threads 16 evenly distributed on the outer surface of the rotor body 15 of the rotor 13 and there is a rotation gap between the thread 16 of the rotor 13 and the inner wall of stator 14. Rotor body 15 is a rotational symmetry body with an increasing diameter from top to bottom, and therefore the rotation clearance is greater in the upper section (L1). Section L1 is the processing section of the raw food material, which is guided from the inlet, and located at the top of the rotor body 15 and corresponds to the soy milk return filter 17 at the top of the
    Petition 870180165801, of 12/20/2018, p. 33/44
    19/24 stator 14. The rotation clearance in the spray section L2 is medium in size (ie larger than section L1, but smaller than section L3). Section L2 is intended for crushing the feed material and is located in the middle part of the rotor body 15 and corresponds to a middle-upper part of the grinding plate 19 of stator 14. The rotary clearance reaches its minimum size of about 1.0mm in the L3 grinding section, where the feed material is subjected to a combination of actions such as crushing, pressing, mixing, friction, twisting and grinding.
    [0038] The section L3 is located in a middle part of the rotor body 15 and corresponds to a lower part of the grinding plate 19 of the stator 14. Below the grinding section L3 there is a separation section between the juice and the residue L4 , which is at the level of the separator filter between juice and residue 18 of stator 14. Through a slow rotation of rotor 13 inside stator 14, the feed material is guided, broken, pulverized, crushed and separated as it moves towards down towards the opening, from the top to the bottom, where the soy milk is finally discharged. The combination of these actions is carried out due to the different clearance sizes (that is, the width of the space between the outer surface of the rotor and the inner surface of the stator) in different sections.
    [0039] As shown in figure 9, grinding (between the lower middle part of the grinding plate 19 grinding is defined by the height of the clearance in section L3 is the clearance of the rotor body and the stator part 14). Thread clearance 16, which is gradually
    Petition 870180165801, of 12/20/2018, p. 34/44
    20/24 reduced from top to bottom. In this embodiment the grinding clearance in the grinding section has a width D of about 0.8 mm and an L3 length of about 25 mm. Since the grinding process in the grinding section is carried out at a low speed, similar to a traditional stone mill, which processes the feed material with a combination of actions, such as crushing, pressing, mixing, friction , twisting and grinding. Consequently, the food material can be ground to finer particles, so that higher levels of nutrients can be extracted, and in turn increases the rate of absorption of the levels of nutrients by the human body.
    [0040] The clearance at point L4 is for the separation between the juice and the residue, with a gradually increased size from top to bottom, considering a profile of a bell mouth. In this embodiment, the bell mouth has a vertical side wall that extends straight downward. The separation gap between the juice and the waste has an L4 length of about 25 mm, a width H of about 2.0 mm and a gap G for discharging the waste of about 1.2 mm.
    [0041] Housing 11 can take shape. An upper cover 12 is arranged on the upper part of the housing 11 and has an inlet 20. The axis of rotation 32 in the central part of the rotor 13 has an upper end positioned next to the upper cover 12, that is, the upper end of the rotating end is located in the positioning hole 29 of the top cover 12. The inlet 20 is offset in relation to the rotation axis 32 of the rotor 13. The
    Petition 870180165801, of 12/20/2018, p. 35/44
    21/24 inlet 20 is connected to the gap between rotor 13 and stator 14 by the threads 16 of rotor 13. The feed material enters the gap in inlet 20 in order to pass through the various transformation phases.
    [0042] The upper cover 12 and the housing 11 are connected via mobile connection means. In this embodiment, the movable connection means include the claws 21 and the slot grooves
    22. The locking jaws 21 are spaced around the periphery of a lower surface of the top cover 12, and the engagement grooves 22 are spaced around the periphery of a top surface of the housing 11. The jaws 21 are locked with the slots 22, respectively.
    [0043] The table 23 (see Fig. 4) is formed in the central part of the base of the housing 11. The table is at a higher level than the plane in which a lower end of the rotor body 15 makes contact with the base of the housing. housing 11. The table has a through hole in the center to allow the axis of rotation 32 of the rotor 13 to pass through it. A recess hole with a specific shape is made in the bottom surface of the rotor 13, to complement the shape of the table, so that the bottom surface of the rotor 13 matches the base of the housing 11 (that is, with the table) with at least least one sealing element disposed between them.
