In addition, the steam air retort has a variety of safety features and design characteristics, such as negative pressure safety device, four safety interlocks, multiple safety valves and pressure sensor control to ensure the safety and stability of the equipment. These features help prevent manual misuse, avoid accidents and improve the reliability of the sterilization process. When the product is loaded into the basket, it is fed into the retort and the door is closed. The door is mechanically locked throughout the sterilization process.

The sterilization process is carried out automatically according to the entered microprocessor controller (PLC) recipe.

This system uses steam heating to heat food packaging without using other heating media, such as water in the spray system as an intermediate medium. In addition, the powerful fan will ensure that the steam in the retort forms an effective circulation, so that the steam is evenly distributed in the retort and improves the heat exchange efficiency.

During the entire process, the pressure inside the sterilization retort is controlled by the program through an automatic valve for feeding or discharging compressed air. Since it is a mixed sterilization of steam and air, the pressure in the retort is not affected by temperature. The pressure can be freely set according to the packaging of different products, making the equipment applicable to a wider range of applications (applicable to three-piece cans, two-piece cans, flexible packaging bags, glass bottles, plastic packaging, etc.).

The temperature distribution uniformity in the retort is +/-0.3℃, and the pressure is controlled at 0.05Bar. Ensure the efficiency of the sterilization process and the stability of product quality.

To sum up, the steam air retort realizes comprehensive and efficient sterilization of products through mixed circulation of steam and air, precise temperature and pressure control, and efficient heat transfer mechanism. At the same time, its safety features and design characteristics also ensure the safety and stability of the equipment, making it one of the commonly used sterilization equipment in food, beverage and other industries.
