摘要： A new method and apparatus for thawing frozen food product utilizing desuperheated gas thawing medium near its saturation point. The transfer of the latent heat of condensation from the thawing medium to the frozen food product immediately condenses the thawing medium into a condensate liquid, after which it is recycled back through the refrigeration system. Since the thawing medium quickly condenses upon giving up energy to the frozen food product, it falls away from the upper surface of the thawing deck tube interiors, being replaced by additional gaseous thawing medium near its saturation point, which in turn condenses upon giving up heat, and the process continues until the food product is completely thawed. Since the state of the thawing medium is consistent throughout the thawing deck tubes, the temperature along the length of each of the tubes is uniform.

摘要： A new method and apparatus for freezing food products utilizing a conventional refrigeration cycle. Refrigerant is fed into an array of heat transfer tubes mounted for immersion in a container of perishable food product whereby heat is transferred from the food product to the refrigerant causing the food product to freeze within a predetermined radius of each heat transfer tube. Each heat transfer tube is comprised of an outer fluid conveying member and an inner fluid conveying member that is generally coaxial or concentric with the outer fluid conveying member. After the food product is frozen, the food product container is lowered, leaving the frozen food product suspended by the heat transfer tubes. A support is placed under the frozen product. The frozen product is removed from the apparatus by heating the tubes so as to thaw a quantity of frozen material in the immediate vicinity of the tubes, which causes the weight of the product to shift from the tubes to the support. The frozen product may thence be moved for storage, shipping, etc.

摘要翻译： 一种利用常规制冷循环冷冻食品的新方法和装置。 将制冷剂送入安装用于浸入易腐食品的容器中的传热管阵列中，由此将热量从食品转移到制冷剂中，导致食品在每个传热管的预定半径内冻结。 每个传热管由外部流体输送构件和与外部流体输送构件大致同轴或同心的内部流体输送构件组成。 在食品冷冻后，食品容器被降低，使冷冻的食品悬浮在传热管上。 支持被放置在冷冻产品下。 通过加热管将冷冻产品从设备中取出，以解冻紧邻管的冷冻材料的数量，这导致产品的重量从管转移到支撑体。 因此，可以将冷冻产品移动以进行存储，运输等。
