    REFRIGERATION OR FREEZER DEVICE TECHNICAL FIELDThe present invention relates to a refrigeration or freezer device according to the pre- characterizing portion of Claim l.
    TECHNICAL BACKGROUND AND PRIOR ART It is a known problem that whenever introducing food material in a continuouslyrunning freezer there are challenges with warrn products sticking to cold surfaces.Especially the perforated trough bottom or conveyor carrying and transporting the foodin a partly or semi-fluidized bed freezer tends to clog with pieces of foodstuff, ice andsnow. This limits the time between defrosting of the freezer and also decreases the freezing result resulting in pieces of food being stuck together.
    In US 4,062,202 a freezer is described in which the tendency of sticking together offood material, as e.g. French fries or peas, on the mesh belt food conveyor is preventedby introducing hot air into an intemal duct in the food weir. This arrangement iscomplicated as it first of all necessitates a food weir and moreover must feed hot air intothe weir. The food can nevertheless stick to the mesh belt food convelyor in spite of theheated food weir which implies that the conveyor must be cleaned often.
    An object of the invention is to provide a refrigeration or freezer device, whicheliminates the above described problems. The object is achieved with the refrigeration or freezer device according to the characterizing portion of Claim 1.
    Preferred embodiments of the refrigeration or freezer device according to the invention have been given the characterizing features which appears in the sub claims.
    The refrigeration or freezer device according to the invention comprises substantiallyless loose parts than corresponding known freezers which are provided with arrangements to avoid sticking of food material.
    The invention focuses on avoiding any foodstuff, ice or snow sticking to the trough rather than mechanically removing what has already accumulated.
    The refrigeration or freezer according to the invention is furthermore easy to manufacture industrially and is also very effective in use.
    SHORT DESCRIPTION OF THE DRAWINGSThe invention is described in the following with reference to the attached drawings,which show a preferred embodiment. Nota bene that the figures are schematic and that details thereby can be left out therefrom.
    Fig. l shows schematically a perspective view of a refrigerator or a freezer with a refrigeration or freezer device according to the invention.
    Fig. 2 shows a perspective view of a part of the perforated trough in the refrigerator or freezer of Fig. l.In Fig. 3 is shown a part of the refrigerator or freezer device according to the invention.Fig. 4 shows a side view of the refrigerator or freezer device according to the invention.
    Fig. 5 shows a section after line A-A of the refrigerator or freezer device according to the invention.
    DETAILED DESCRIPTION OF THE INVENTIONDetails, which refer to substantially alike parts of the different embodiments, have been given the same reference numbers.
    With reference to the drawings in Fig. l is shown a refrigerator or freezer l forrefrigeration or freezing treatment and transportation of a material, consisting of piecegoods or granules of solid material. The refrigerator or freezer l comprises a perforatedtrough bottom 2 which is divided into two parts 2a and 2b, wherein the part 2b ispreferably the refrigerator or freezer device according to the invention. The refrigeratoror freezer furtherrnore comprises a house 3, fan devices 4 and refrigerator or freezingaggregates 5. Moreover, the refrigerator or freezer l is provided with an inlet 6 and anoutlet 7. The inlet trough part 2b comprises a heated trough bottom which is providedwith electrical heating cables 8 in a zigzag pattem, as shown in Figs. 3 to 5. The troughbottom parts 2a and 2b are perforated having holes 9 spread over their surfaces. The transportation of the product, as food material, is shown by arrows l0 and ll. 12 and l3 denotes coupling elements to join several portions of the trough bottom 2 together. Atthe end of each path part 2a or 2b are portions of the trough bottoms With a coupling ononly one side and Where the other side is Without coupling as the side 14 illustrated in Figs. 3 to 5.
    As shoWn in the drawings tWo or more portions of the trough bottom, the bottom 2a asWell as the bottom 2b, can be coupled together to form a longitudinal path through therefrigerator or freezer l. The trough portion 2b is situated on a higher level than thetrough portion 2a so that food material entering into the inlet 6 Will first be transportedalong the trough portion 2b and thereafter fall doWn on the trough portion 2a and finally be transported to the outlet 7 and out from the refrigerator or freezer.
    By heating the first part 2b of the trough bottom 2 the food material is prevented frombeing stuck to the trough bottom part 2b Which makes the refrigerator or freezer more efficient.
    The transportation of the food material is performed preferably by achieving a semi-fluidized refrigerator or freezer, i.e. the fan devices 4 bloWing air from the refrigeratingor freezing elements through the perforated troughs 2a and 2b so that only a part of thefood material is in contact With the trough bottom, Whereby the trough bottom parts 2aand 2b are subj ected to an asymmetric vibration movement to facilitate the transportation.
    Of course the refrigerator or freezer device according to the invention can be provideWith a perforated transport band or a fully fluidized refrigerator or freezer, i.e. arefrigerator or freezer Which transports the food material on a perforated transport band moving only in one direction.
    Hence, the invention is related to a refrigerator or freezer l of the kind Where theproduct by means of a fan device 4 is fluidized or semi-fluidized (lower energy as partof the products are always in touch With the trough bottoms 2a and 2b) and Where theproduct, as e. g. fruit or vegetables, in small pieces is fed first through the inlet 6 to apart 2b and thereafter is fed further to part 2a and finally out from the refrigerator orfreezer through an outlet 7. The product is preferably fed by means of an asymmetric movement in the length direction of the troughs 2a and 2b.The trough bottoms 2a and 2b are provided With through holes 9 for letting the air from the fan devices 4 and therefrigerating or freezing aggregates 5 blow through the holes 9 and lift and freeze,alternatively, the product, see EP 1163048 or WO 00/45949.
    One disadvantage is that the product can be clogged and stick to the first trough part 2bdue to temperature differences between trough bottonis and product When entering therefrigerator or freezer. This is norrnally eliniinated by vibrations or cleaning of the first trough as Well as replacing the first trough part 2b With a new cleaned one.
    By heating the first trough bottom part 2b the product Will be prevented to stick to thefirst trough bottoni part 2b and by arriving to the second trough bottoni part 2a theaffect does not exist anyniore as the product is already partly or entirely frozen aroundits periphery. The heating is perforrned by providing the first trough bottoni part 2b orthe separate parts of trough bottoni part 2b With electrical heating cables 8 for electricalloops or heating liquid for heating the trough part 2b.
    The invention is of course not liniited to the enibodinient described above, but can be niodified Within the franie of the patent clainis.
