CLEANING OF FOOD MATERIAL BY USING A BACTERIA-REMOVED WATER AND STERILIZED WATER AND RECYCLE SYSTEM OF THE WATER

摘要

PROBLEM TO BE SOLVED: To provide a method for cleaning food materials capable of maintaining the freshness of the food materials and facilitating the maintenance control of the quality by cleaning or thawing the food material by using a specific bacteria-removed water. SOLUTION: This method for cleaning food materials is to perform cleaning and thawing the food materials by using a bacteria-removed water C produced by a method for producing dissolved oxygen in water by irradiating either one of ozone or a mixed gas phase of ozone and air with ultraviolet rays (laser) of 240-310 nm to convert ozone to a singlet oxygen, then irradiating visible rays of 600-650 nm or near infrared rays of 1200-1300 nm each singly, simultaneously or successively to produce a gas phase in which the produced singlet oxygen transits to a ground state by an induced release of an electromagnetic wave or is in the 2 processes of the transition, and dissolving the gas phase into water by showering water through the above gas phase or increasing the contact area of the gas phase and water by a water jet. Further, it is preferable to transfer the bacteria-removed water C to a food material treating chamber 2 for cleaning the food materials, and introduce the used water after the cleaning into a bacteria removing device 1 again for regenerating the water as the bacteria-removed water C and used by circulation.
