This water immersion retort is suitable for vacuum-packed food and flexible packages
Ⅰ. Description
The water immersion retort features unique liquid flow switching technology for uniform internal temperature. Preheated hot water from a tank enables fast heating and sterilization, with hot water recycled post-process for energy efficiency.
Ⅱ. Advantages
- Uniform water flow: Flow direction switching ensures vertical/horizontal uniformity, delivering water to each product tray’s center for dead-end-free sterilization.
- HTST treatment: Preheated hot water enables high-temperature short-time sterilization.
- Deformable container compatibility: Water buoyancy protects containers under high temperatures.
- Large/high-viscosity food suitability: Rotation ensures even heating of large canned/high-viscosity foods, with water buoyancy safeguarding packaging during rotation.
Ⅲ. Working Principle
Load product baskets, close the door (locked via triple safety interlocks for full-process mechanical security). The PLC controls automatic sterilization per preset recipes:
- Inject preheated hot water into the retort; circulate via high-flow pumps and optimized pipes.
- Steam injection heats water for sterilization; flow switching ensures uniform heat distribution.
- Programmed pressure control (via automatic air injection/discharge) adapts to 3-piece cans, 2-piece cans, flexible/plastic packages, etc.
- Optional hot water recovery during cooling saves energy.
- An alarm signals completion; unload for the next batch.
Temperature uniformity: ±0.5℃; pressure control precision: 0.05 Bar.
Applications
