Working Principle

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

Water retained at bottom of retort, automatically injected at start of heating if needed. For hot-filled products, water can be preheated in hot water tank then injected. Throughout sterilization, water circulates through high-flow pump and distribution plates at top, spraying evenly from top to bottom for heating.

Tube heat exchanger ensures sterile heating and cooling - process water on one side, steam/cooling water on other side, preventing contamination.

Internal pressure controlled by program through automatic valves injecting or exhausting compressed air. Spray-type sterilization allows free pressure setting independent of temperature, suitable for various packaging (three-piece cans, two-piece cans, soft pouches, glass bottles, plastic packaging).

Temperature uniformity: ±0.5°C, Pressure control: ±0.05Bar

Advantages: Precise temperature control (12-segment), pressure control for various packaging, high cleanliness (no chlorine needed), FDA/USDA compliant, energy saving (30% steam reduction).
