PROBLEM TO BE SOLVED: To uniformly and stably cool even a soft object to be cooled such as a food without deforming it, and to improve the quality of the object to be cooled.SOLUTION: A food cooling apparatus 1 comprises a tunnel portion 2, a liquefied gas supply portion 5 for supplying a liquefied gas into the tunnel portion 2, and a stirring fan device 10 for stirring the low temperature gas in a cooling space 24. A baffle plate 13 is provided below a stirring fan device 10, a partition wall 25 for partitioning a cooling space 24 into an upper part and a lower part is provided below the baffle plate 13, a plurality of communication pipes 26 for communicating the upper and lower space parts are formed in the partition wall so that liquefied gas having hit the baffle plate 13 passes around the baffle plate 13 to flow from the upper space 24a to the lower space 24b, and the liquefied gas supply portion 5 supplies the liquefied gas so that the liquefied gas flows from the upper space 24a to the lower space 24b through the communication pipe 26 while maintaining a pressurized state of the upper space 24a.SELECTED DRAWING: Figure 1 【課題】本発明は、柔らかい食品等の被冷却物であっても変形することなく均等に安定して冷却することができ、被冷却物の品質を向上することができることを課題とする。【解決手段】トンネル部２と、トンネル部２内に液化ガスを供給する液化ガス供給部５と、冷却空間２４内の低温ガスを攪拌する攪拌ファン装置１０とを備える。攪拌ファン装置１０の下方には、邪魔板１３が設けられ、邪魔板１３の下方には、冷却空間２４を上下部分に区画する区画壁２５が設けられ、邪魔板１３に当った液化ガスが邪魔板１３の周囲を通過して上部空間２４ａから下部空間２４ｂに流れるように、上下空間部を連通する連通パイプ２６が、区画壁に複数形成され、液化ガス供給部５は、上部空間２４ａの加圧状態を維持しながら上部空間２４ａから連通パイプ２６を介して下部空間２４ｂに液化ガスが流れるように、液化ガスを供給する。【選択図】図１
