    摘要: A tunnel freezer is cooled by selectively supplying liquid nitrogen to banks of spray nozzles. The banks are switched on and off as required so that at any given time the pressure upstream of each operational spray nozzle will be substantially constant at a level which closely approximates the maximum heat transfer coefficient associated with the spray nozzle or the maximum effectiveness of the spray nozzle or a balance therebetween. The invention is in contrast to the prior art where the flow of liquid nitrogen to the spray nozzles is continuously varied in response to the thermal load.

    摘要: An evaporative cooler for pouches containing a liquid or semi-liquid material such as tomato paste. The cooler includes a housing, a plurality of generally horizontal endless conveyor assemblies arranged one above the other within the housing in vertically spaced relation and each including an endless conveyor member trained over feed and discharge pulleys at the feed and discharge ends of the conveyor assembly. The upper runs of the conveyor assemblies are driven in successively opposite longitudinal directions within the housing so that a pouch may be deposited on the feed end of the uppermost conveyor assembly, move in one longitudinal direction along the upper run of the uppermost conveyor assembly to the discharge end of the uppermost conveyor assembly for discharge onto the feed end of a lower conveyor assembly, thereafter move in an opposite longitudinal direction along the upper run of the next lower conveyor assembly to the discharge end of the lower conveyor assembly for discharge onto the feed end of a yet lower conveyor assembly and proceed in this manner progressively along all of the conveyor assemblies until discharged from the discharge end of the lowermost conveyor assembly.

    摘要: Process and device for freezing substances contained in a receptacle, in which the receptacle (4) is placed on a support (7) and is moved along the support in a path. The support is a conveyor, preferably a vibratory conveyor, and is maintained partially immersed in a liquefied gas (13). The level of the liquefied gas (13) does not exceed the height of the substance in the receptacle (4). The vibratory conveyor comprises a vibrating trough (1) having two opposed walls (9) defining between them a guide channel (3) for the receptacles (4) and, on opposite sides, a chamber (10) for distribution of liquefied gas. A device (11) provides liquefied gas to each chamber (10). The bottom (7) of the vibrating trough (1) is of embossed sheet metal.

    摘要: A pelletizer for making pellets from a liquid or semi-liquid food product has two molding rolls between which the food product is formed into pellets. The rolls have teeth of complementary shape, and the teeth of at least one roll have axially spaced apart recesses. The rolls are cooled with a refrigerant during the molding operation. By the means of the pelletizer, frozen pellets are made from a liquid or semi-liquid food product which, prior to molding, is refrigerated into moldable consistency before being supplied to the nip between the two cooperating molding rolls which are cooled during the molding operation so as to form surface-frozen pellets which are thereafter subjected to final freezing.

    摘要: Frozen slabs of fish are introduced one at a time to one end of a conveyor having a bed of laterally spaced plastic strips forming slots therebetween. Beneath each slot is an endless chain having a series of upwardly directed fingers thereon. The fingers are engageable with the various slabs so as to advance the slabs to a location beneath an assembly of water jet devices, each device including a pivotal arm having a nozzle at one end thereof. A barrel cam has a plurality of tracking grooves, the pivotal arms having cam followers depending downwardly therefrom into the tracking grooves of the barrel cam. As the slabs are successively advanced beneath the liquid jet devices, the jets cut the particular slab into individual portions. Advancement of the now severed portions cause the portions to be moved onto a plurality of tilt strips which prevent the cut edges from freezing together. The individual portions are then delivered onto a spreader conveyor assembly comprised of three angularly oriented sets of rollers, two of the sets flanking the first or central set and causing the individual portions to traverse a diverging path for subsequent processing.

    摘要: Plate freezer apparatus has a plurality of vertically disposed refrigerated plates separated from each other by spacer frames to define a plurality of open topped compartments to receive product to be frozen. The assembly of plates and spacer frames are held together by spring tensioned rods which apply a compressive force to the assembly. Each plate has a number of wedge surfaces and a plate separating device engages the wedge surfaces of an adjacent pair of plates to thereby separate those plates to enable the spacer frame and frozen material therebetween to be withdrawn. The frozen material is removed from the spacer frame which is then re-inserted between the separated plates and the separating device removed before the compartment is refilled with product to be frozen.
