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： A food freezer having a mechanical refrigeration system comprising first and second closed-loop fluid circuits, wherein the first fluid circuit employs carbon dioxide as its refrigerant and transfers heat to the second fluid circuit, which in turn transfers heat to the environment or to another fluid circuit. In the first fluid circuit evaporator, carbon dioxide is maintained at pressures between 60.4 psig and 120 psig. In a preferred embodiment of the invention, the freezer employs at least two separate blowers or fans for circulation of air or other gas in the freezer enclosure. One blower/fan operates continuously to maintain circulation of cold air or gas in the freezer. The other blower/fan operates intermittently or at variable speeds to vary air flow across the evaporator, and thereby increase or decrease heat transfer from the freezer interior to the first fluid circuit evaporator to maintain the freezer interior at a desired temperature or within a desired temperature range.
摘要翻译：一种具有包括第一和第二闭环流体回路的机械制冷系统的食品冷冻机，其中所述第一流体回路采用二氧化碳作为其制冷剂并将热量传递到所述第二流体回路，所述第二流体回路又将热传递到环境或另一流体电路。在第一流体回路蒸发器中，二氧化碳保持在60.4psig至120psig之间的压力。在本发明的优选实施例中，冷冻器采用至少两个分开的鼓风机或风扇，用于在冷冻箱中循环空气或其它气体。一个鼓风机/风扇连续运转，以保持冷藏室内冷空气或气体的循环。另一鼓风机/风扇间歇地或以可变速度工作以改变蒸发器上的气流，从而增加或减少从冷冻室内部到第一流体回路蒸发器的热传递，以将冷冻室内部保持在所需温度或期望温度范围。
