STERILIZER OF COOLING STORAGE

PROBLEM TO BE SOLVED: To enable efficient sterilization in a storage.SOLUTION: A sterilizer of a cooling storage is provided with a storage chamber 13 capable of storing food, a cool air supply device 16 circularly supplying cool air to the storage chamber 13, and an ultraviolet lamp 20 arranged in the storage chamber 13, and can execute three modes of a quick cooling operation of cooling high-temperature food in a short time, a cold insulation operation of keeping the food after cooling at a prescribed cooling temperature, and an operation shutdown. The ultraviolet lamp 20 having a peak value of ultraviolet strength in ultraviolet strength-temperature characteristics in a prescribed temperature zone Y of the temperature in the storage present over cases when executing all the operation modes, is selected, and is provided with an in-storage temperature sensor 49 which detects an in-storage temperature, and lamp control means 40 which can light the ultraviolet lump 20 only in the case when an in-storage temperature detected with the in-storage temperature sensor 49 is in the prescribed temperature zone Y.
