SOLUTION: An intermediate opening part 8c is provided on the middle part of a duct 8 for forming the circulation route of air by communicating the upper side space and lower side space of a container 5, a shutter 20 made of a shape memory alloy is provided on a position facing the intermediate opening part 8c and the shutter 20 is formed in a shape to be an open posture at the time of being turned to a high temperature by circulated heating air and be a closed posture at the time of being turned to a low temperature by circulated cooling air. Thus, the possibility that the products 6 are preserved at a high temperature state for the long period of time before being sold is reduced and the decline of the quality and taste of the products 6 is minimized.
