Abstract: A food freezer for continuous freezing of food products utilizing a helical conveyor for transporting the food products through an enclosure in which the food products are cooled. Mechanical refrigeration apparatus employs a refrigerant to cool an atmosphere gas which is circulated across the food products within the enclosure. The refrigerant is also employed to subcool a cryogen which also cools the same food products.

Abstract: Refrigeration apparatus for cooling or freezing products such as protein materials includes a drum through which heat transfer fluid is circulated. A belt is wrapped around part of the drum surface and the product to be refrigerated is applied to the drum surface, being pressed thereagainst by the belt. Either liquid or triple point carbon dioxide is circulated through the drum to cool the product in contact therewith. Other heat transfer fluids such as D-Limonene or DOWTHERM may also be circulated through the drum. A tank and related apparatus for cooling the heat transfer fluid is also disclosed.

Abstract: A food freezer having a thermally insulated enclosure and an endless conveyor having a loading section, a food freezing section and an unloading section. Blowers circulate gas throughout the interior of the enclosure, and devices for injecting liquid CO.sub.2 to preferably cause CO.sub.2 snow particles to impinge upon the food products on the belt are located at selected positions about the belt and may be at various vertical levels, some of which are preferably at least slightly above the belt. By piping the liquid CO.sub.2 so that it flows only upward and/or horizontally toward the spray nozzles within the thermally insulated enclosure, any solid CO.sub.2 that may accumulate adjacent the upstream side of the spray nozzle orifices is melted by CO.sub.2 vapor which gravitates upward in the vertical piping.

Abstract: A cryogenic freezer apparatus for food products includes a conveyor within a thermally insulated enclosure. A cryogen injecting unit is located in said enclosure adjacent the opening thereof, and responsive to a cryogen control signal for introducing liquid cryogen in said enclosure. A blower unit in said enclosure directs cryogen vapor away from said enclosure opening toward the interior of said enclosure. The output of said blower unit being controllable by a blower control signal. A sensing unit within said enclosure senses the cooling capacity of the cryogen vapor at the enclosure opening and generates a sensor output signal which is indicative of the amount of cryogen vapor escaping out of said opening. A control unit, coupled to said sensing unit, said injecting unit, and to said blower unit generates a cryogen control signal and a blower control signal in response to the sensor output signal. Cryogen vapor escaping from the enclosure is limited to an amount needed to maintain an air lock, thus preventing air intrusion into the enclosure.

Abstract: A freezer includes an insulated enclosure for maintaining low temperatures therewithin and a conveyor belt that carries food products throughout the enclosure. The conveyor belt includes a straight-line path section and at least one helical path section and is driven by vertical drive elements carried by a rotating drum about which the conveyor helical path section is located. Upon entering a helical path section from a straight-line path section, the conveyor belt undergoes expansion only, with the inner ends of its transverse rods maintaining a precise spacing which allows smooth interengagement between heads at the inboard ends of the rods and the leading surfaces of the vertical drive elements that are located along the circumference of the rotating drum which defines the curved helical path. Because of the improved arrangement, both an ascending helical path and a descending helical path can be established within a single freezer with both rotating drums simply driven by a single motor.
