Tuna can Sterilization Retort

Working principle:

Put the product into the sterilization retort and close the door. The retort door is secured by triple safety interlocking. Throughout the whole process, the door is mechanically locked.

The sterilization process is automatically carried out according to the recipe input to the micro-processing controller PLC.

This system is based on the direct heating for food packaging by steam, without other heating media (for example, the spray system is used water as an intermediate medium). Since the powerful fan forces the steam in the retort to form a cycle, the steam is uniform. Fans can accelerate the heat exchange between steam and food packaging.

Throughout the whole process, the pressure inside the retort is controlled by the program by feeding or discharging compressed air through the automatic valve to the retort. Due to steam and air mixed sterilization, the pressure in the retort is not affected by temperature, and the pressure can be set freely according to the packaging of different products, making the equipment more widely applicable (three-piece cans, two-piece cans, flexible packaging bags, glass bottles, plastic packaging etc.).
