Pasteurization machine

Machine Functions

The fully automatic pasteurization machine is a professional food sterilization equipment integrating low-temperature constant temperature water bath sterilization, slow heating, color and freshness preservation. Adopting classic low-temperature pasteurization technology, it kills Escherichia coli, pathogenic bacteria and spoilage bacteria while retaining the original nutrition, flavor, color and taste of food without damaging active ingredients. Equipped with circulating water bath surrounding heating structure, the machine realizes uniform water temperature without temperature difference. The intelligent PLC constant temperature timing system precisely sets sterilization temperature and holding time, avoiding incomplete sterilization and food deterioration caused by overheating. Adopting continuous mesh belt conveying operation, it automatically completes feeding, constant temperature sterilization, slow cooling and uniform discharging, supporting 24-hour non-stop continuous production. The built-in water circulation filtration system realizes water recycling with energy saving and low operation cost. Featuring simple operation, parameter memory and fault self-inspection, it can work independently or connect with filling, sealing, labeling and packaging equipment to build full-automatic sterilization lines for dairy products, beverages, prefabricated dishes and pickled products, solving the pain points of poor taste, nutrition loss and unstable quality caused by traditional high-temperature sterilization.
