PROBLEM TO BE SOLVED: To attain food cooling where the weight and temperature of food are adjusted desirably, in a food machine having a vacuum cooling function.SOLUTION: A food machine having a vacuum cooling function includes decompression means 3 and pressure recovery means 4, and is configured to sequentially execute a first cooling step of decompressing a treatment tank 2 to vacuum-cool food F, and a second cooling step of further cooling the food F in a state of suppressing moisture evaporation compared to the first cooling step. The food machine includes a weight sensor 5 configured to detect a weight of the food F, and a food temperature sensor 6 configured to detect a temperature of the food F. The first cooling step is continuously performed until the weight of the food F in the treatment tank 2 becomes a target weight, and the second cooling step is continuously performed until the temperature of the food F in the treatment tank 2 becomes a target temperature.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】真空冷却機能を有する食品機械において、食品の重量と温度とを所望に調整した食品冷却を実現する。【解決手段】減圧手段3と復圧手段4とを備え、処理槽2内を減圧して食品Fを真空冷却する第一冷却工程と、この第一冷却工程よりも水分蒸発を抑制しつつ食品Fをさらに冷却する第二冷却工程とを順次に実行する。食品Fの重量を検出する重量センサ5と、食品Fの温度を検出する品温センサ6とを備える。第一冷却工程は、処理槽2内の食品Fが目標重量になるまで行い、第二冷却工程は、処理槽2内の食品Fが目標温度になるまで行う。【選択図】図1
