Water Immersion Retort Machine

Horizontal Static Water Immersion Retort Sterilization Machine

Features:

1. Uniform heat distribution and no blind angle for sterilization;

2. Preheat the process water in the upper storage vessel in advance, shorten the sterilization time and improve the working efficiency;

3. Process water can be used repeatedly, saving energy, time, manpower, and reducing the production cost;

4. Short process time  and high temperature preserve food flavor and nutrition;

5. Perfect pressure control system, efficiently avoiding the containers deformation and package break;

6. Continually monitor the temperature inside the retort, keeping the temperature difference ±0.5 ℃;

7. Siemens PLC automatic control system and touch screen, easy to operate;

8. System will make alarm calls automatically when the temperature, the pressure, the water level, or any other kinds of error occur.

Applicable Scope:

1. Canned Containers: tin can, aluminum can

2. Plastic Container: PP bottle, HDPE bottle

3. Soft package: Aluminum foil bag, transparent bag, vacuum bag, retort pouches, doy-packs, etc..

Description and Working Principle:

Water Immersion Retort is usually composed of upper vessel and lower vessel. The top one is used to store preheated process water and recycle the hot process water before cooling process. The bottom one is the retort for sterilization.

After the food containers were loaded into the baskets and enter the retort, the preheated process water is delivered into the retort through water spreader on the top of retort, the water level was controlled and monitored by water level gauge outside the retort.

The steam enter the retort through the water spreader or additional steam spreader and heat the process water continually until the temperature rise to scheduled sterilization temperature.

The circulation pump recycle the hot water with a high speed and assure the uniform heat distribution inside the retort.

After the sterilization is completed, the hot water will be recycled to the top tank and stored for next batch sterilization. Then the cooling water will be filled into the retort directly to make the food container cool down.
