Working Principle

Products loaded into baskets enter retort, cylinders press individually, door closes with triple safety interlock. Sterilization process automatically controlled by PLC.

Hot water from hot water tank injected into retort at start. Hot water mixed with products, continuously circulated through high-flow pump and scientifically distributed water pipes, injected with steam through water-steam mixer for continued heating and sterilization.

Process water in retort achieves uniform water flow at any vertical and horizontal position through rotating body rotation, ensuring excellent heat distribution.

Internal pressure controlled by program through automatic valves. Water immersion sterilization allows free pressure setting independent of temperature, suitable for various packaging.

Cooling stage can choose hot water recovery and replacement to recycle sterilization hot water, saving thermal energy.

Temperature uniformity: ±0.5°C, Pressure control: ±0.05Bar. Entire process rotation speed and time determined by product sterilization process.

Advantages: Uniform water flow distribution (no dead corners), high-temperature short-time processing (pre-heated hot water), suitable for fragile packaging (water buoyancy protection), suitable for large packaging (effective heating of high-viscosity food center), simple and stable rotation system structure.
