PROBLEM TO BE SOLVED: To securely prevent propagation of miscellaneous fungi, by equipping a sterilizing means to sterilize the inside of a food machine during the stopping of the food machine. SOLUTION: A can body 1 of a vacuum cooler has a structure tightly closable by a door, stores food in the can body 1, and reduces the pressure in the can body 1 to perform vacuum cooling. An ultraviolet irradiating means 2 by an ultraviolet lamp, etc., is equipped as a sterilizing means on the side wall of the can body 1. The ultraviolet irradiating means is partitioned from the inside of the can body 1 by a transparent member 3 made of quartz glass and a cover 4 is equipped on the outer part of the can body 1. The vacuum cooler stores food in the can body 1 using an operation wagon 5, etc., with multiple shelves to perform vacuum cooling operation. When the vacuum cooling operation of the vacuum cooler is finished, the ultraviolet irradiating means 2 is actuated during stopping the cooling operation to prevent propagation of miscellaneous fungi in the can body during stopping the cooling operation. Generation of offensive odor caused by propagation of miscellaneous fungi can be prevented by that sterilization. |
