The development and application of industrial oxygen concentrators in the food hygiene and safety industry have four key aspects:
① Kill microbial strains – sterilization, disinfection, and sterilization;
② Air oxidation technology for decomposing organic or inorganic compounds into environmental pollutants – deodorization and purification;
③ It is the decomposition of substances that reflect the metabolism of vegetables and fruits, inhibiting the entire ripening process – refrigeration;
④ Dissolve organic chemical pesticide residues. The theoretical basis for the scientific research application of Sifang depends on the strong air oxidation solving characteristics and unstable and easily decomposable characteristics of industrial oxygen concentrators in China.
