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 tunnel freezer uses carbon dioxide snow to directly contact product carried on a conveyor belt passing through the freezer. Fans are provided above and below the upper conveyor belt run carrying the product, with the fans above and below having downwardly directed exhaust. Trough-shaped deflector plates are provided adjacent the lower fans to circulate a flow adjacent the underneath surface of the upper conveyor belt run. Preferably, circulation adjacent the upper conveyor belt run is generally parallel to the upper conveyor belt run, and turning vanes are provided to deflect the flow upwardly through the upper conveyor belt run. Freezers may be provided with one or more cooling zones arranged in series along the path of conveyor belt travel.
摘要翻译： 隧道式冷冻机使用二氧化碳雪直接接触通过冷冻机的传送带上携带的产品。 风扇设置在承载产品的上部输送带行程的上方和下方，上方和下方的风扇具有向下排列的排气。 在下部风扇附近提供槽形偏转板，以使邻近上部输送带运行的下表面的流动循环。 优选地，邻近上传送带行程的循环通常平行于上传送带行程，并且提供转动叶片以使流向上偏转上传送带运行。 冷冻机可以设置有沿传送带行进路径串联设置的一个或多个冷却区域。
