In the mushroom cultivation industry, high pressure sterilizers are mainly used to sterilize the mushroom culture medium and packaging materials to ensure a sterile or low bacterial state for the growth environment of the mushrooms. Mushroom growth requires nutrients and moisture, and if the culture medium or packaging materials contain microorganisms such as bacteria and mold, it can lead to poor mushroom growth, spoilage, and infection by pathogens. Using high pressure sterilizers can effectively kill these microorganisms, ensure a clean and hygienic growth environment for mushrooms, and improve mushroom yield and quality.
