Abstract

The invention provides a storage device and a storage method for fresh products. The storage device for fresh products in some embodiments includes: a fresh product storage warehouse, which can store the fresh product at a temperature above the frozen state; a temperature adjustment unit, which can adjust the temperature inside the fresh product storage warehouse. The temperature is higher than the frozen state; the air flow generation unit forms an air flow in the storehouse of the fresh product storage; the irradiation unit irradiates ultraviolet rays to the air flow to generate ozone or free radicals; and the intermittent irradiation control unit The irradiation unit may be controlled so as to intermittently irradiate the air flow with the ultraviolet rays.

Description

technical field [0001] The present invention relates to a storage device and a storage method for fresh products for storing fresh products using vacuum ultraviolet rays, and for sterilizing fresh products during refrigeration or thawing. Background technique [0002] In the past, the following methods have been used to prevent the growth of mold and bacteria in fresh products: install an ultraviolet lamp in the refrigerator, irradiate ultraviolet light to sterilize the air, or install an ultraviolet lamp in the water tank or piping of the humidifier, and irradiate the humidification water Ultraviolet light to sterilize. [0003] Other methods include generating ozone with a plasma-type ozone generator, spraying ozone water in the refrigerator, or spraying hypochlorous acid in the refrigerator for sterilization. [0004] Patent Document 1 discloses a sterilizing storage device that exposes stored food to air containing oxygen ion radicals and moisture generated by irradiati...
