The "Hot Water Injection Retort Sterilization Device" boasts exceptional temperature and pressure stability due to its unique sterilization method that does not directly spray hot water onto the product. The advantages arising from its structure include the fact that the product remains stationary. Additionally, it enhances safety, maintainability, and durability. With a rich variety of options, it includes energy-saving types with hot water recovery tanks, water-saving types equipped with heat exchangers, energy-saving and water-saving types that incorporate both features, and it also accommodates high-temperature short-time processing methods. An automatic pressure setting system is adopted, which automatically sets the control pressure when the packaging form is determined (manual changes are also possible). It offers easy operation by simply selecting a product from 100 registered patterns. Even at low-temperature sterilization below 100°C, processing with no temperature variation is possible. 【Features】 ■ Ideal uniform temperature distribution, quiet operating sound ■ The product remains stationary (can accommodate small products) ■ Sterilization is possible even if the height of the trays changes ■ Exceptional durability, sanitary properties, and easy maintenance ■ Contributes to low cost with an energy-saving system ■ Water-saving type allows for water reuse ■ Standard equipped with a gas inclusion system ■ Compatible with high-temperature short-time processing type (ST) ■ State-of-the-art automatic control mechanism
