For solid food sterilization, DCW hypochlorous acid generator can be installed. The equipment uses salt and water electrolysis to generate hypochlorous acid disinfectant which is harmless to human body. After sterilization, it can be completely degraded without residue and pungent smell. This hypochlorous acid can be used to sterilize food raw materials, production water, instruments and equipment, and hand washing. The oxidation of hypochlorous acid can kill all kinds of bacteria and microorganisms quickly and widely, and effectively prolong the shelf life of food.
