Regarding cold storage where exposed food is placed, the power-on time of the ozone generator can be appropriately extended to maintain a higher ozone concentration and achieve a good sterilization and preservation effect. Large-scale ozone generators for food storage and preservation are used in food storage warehouses. They are favored by many food companies because of their good effects of sterilization, deodorization and preservation of food.
Ozone sterilization belongs to the field of bacteriolysis. The sterilization is thorough and quick, efficient and broad-spectrum. It has obvious inactivation effects on all germs, molds, fungi, protozoa, and oocysts, and can destroy botulinum toxin. At the same time of disinfection and sterilization, ozone can be reduced to oxygen by itself, with no harmful residues and no secondary pollution. It is an environmentally friendly sterilant; at the same time, it can also avoid the disadvantages of low energy efficiency of ultraviolet disinfection and high pollution by chemical fumigation. In addition to the sterilization and disinfection functions, ozone also has the effect of removing peculiar smell in the food workshop and prolonging the preservation period of fresh fruits and vegetables.
The use of "series of large-scale ozone generators for food storage and preservation" in food cold storage has three effects:
One is to kill microorganisms, disinfect and sterilize.
The second is to oxidize and differentiate organic and inorganic compounds that emit foul smells to remove bad smells in the library.
The third is to control the process of introducing fresh fruits and vegetables into new foods to extend the shelf life of food.
Ozone water can be used for effective cleaning and disinfection of cold storage floors, walls, shelves, and containers. The ozone air sterilization system can effectively suppress the breeding of various microorganisms in the storage, and timely kill various pathogens in the air, thereby preventing food from mildew and rot. Using the "large ozone generator special for food storage and preservation", it can sterilize, disinfect, and deodorize food cold storage, and keep the food fresh. Because ozone is unstable, its use in the cold storage is more beneficial to the storage and preservation of food in the cold storage. Because the product of ozone differentiation is oxygen, it will not leave harmful residues in the stored food. Pass ozone into water to produce ozone water.
The process of ozone sterilization is attributed to the biochemical oxidation reaction. Ozone can oxidize and differentiate the enzymes necessary for glucose in microorganisms such as bacteria, and it can also directly affect bacteria and viruses, destroy their cells and ribonucleic acid, and differentiate DNA, RNA, proteins, lipids, and polysaccharides and other macromolecular polymers. Permeability aberration occurs in the substances in bacteria and other microorganisms, leading to the lysis and death of cells, and the genetic genes, parasitic strains, parasitic virus particles, bacteriophages, mycoplasma and pyrogens (bacterial virus metabolism products, endotoxins) in the dead bacteria Wait for dissolution and degeneration. Most of the ozone used in industry is prepared by gas corona discharge type ozone generator.
