摘要： 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.

摘要： 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.

摘要： 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.
