The spray sterilizer is a common continuous sterilization equipment used in the food and beverage industry for low and medium temperature sterilization, mainly applied to bottled, bagged and boxed products. The whole machine is made of stainless steel, clean and hygienic, complying with food safety standards. It uses circulating hot water to evenly spray on product surfaces for gentle sterilization without damaging packaging or affecting taste. Sterilization temperature and speed can be precisely controlled. After sterilization, products go through warm water cooling and cold water cooling to avoid package breakage caused by excessive temperature difference. With automatic continuous operation, large capacity and stable uniform sterilization, it is widely used in the sterilization of beverages, sauces, condiments, soybean products and other packaged products to ensure shelf life and food safety.
