PROBLEM TO BE SOLVED: To freeze a large amount of food and drinks while keeping freshness.SOLUTION: Refrigeration equipment 1 includes: a sub-zero refrigeration space 12 that can be opened and closed a conductive conveying device 15 on which food and drinks XA1 are placed a caster 26, which allows the conveying device 15 to be carried into and out of the refrigeration space 12 and insulates the conveying device 15 from a floor surface 17, a side surface 18 and a ceiling face 19 that form the refrigeration space 12 and a power source terminal 30, which allows switching between connection and disconnection for the conveying device 15. The refrigeration equipment 1 puts the food and drinks XA1 into a supercooled state by applying a voltage to the food and drinks XA1 in the closed refrigeration space 12, and then freezes the food and drinks.COPYRIGHT: (C)2014,JPO&INPIT【課題】大量の飲食物を、鮮度を保ちつつ冷凍する。【解決手段】冷凍設備1は、開閉可能な氷点下の冷凍空間12と、飲食物XA1が載置される導電性の搬送装置15と、この搬送装置15を冷凍空間12に搬出入可能とすると共に、搬送装置15を、冷凍空間12を形成する床面17、側面18及び天井面19と絶縁するキャスター26と、搬送装置15に対する接続/開放の切替えを可能にする電源端子30と、を備えている。この冷凍設備1は、閉じた冷凍空間12内の飲食物XA1に電圧を印加することで、飲食物XA1を過冷却状態にしてから冷凍する。【選択図】図1
