Abstract: A food material powder supply device 1 of the disclosure includes a supply tank 50 that temporarily stores food material powder in a tank 50A and supplies the food material powder to a processing container 2A of a food processing machine 2, a vacuum device 70 that reduces the pressure inside the supply tank 50 with vacuum pumps 71A and 71B, and a control device 3 that operates the vacuum device 70 to reduce the internal pressure of the supply tank 50 to be equal to or lower than a predetermined atmospheric pressure at which moisture of the food material powder is evaporated and cools the food material powder in the supply tank 50. A stirring member 54 which is driven to rotate during the cooling of the food material powder is arranged inside the tank 50A.

Abstract: A peeling method includes a first decompression step, a pressure-heating step, and a second decompression step. In the first decompression step, an object with a skin to be peeled is placed in a pressure chamber being sealed, and an inside of the pressure chamber is decompressed to a predetermined first negative pressure state. In the pressure-heating step, the inside of the pressure chamber is pressure-heated to a predetermined pressure-heating state after the first decompression step. In the second decompression step, the inside of the pressure chamber is decompressed to a predetermined second negative pressure state after the pressure-heating step.
