Description
The Water Immersion Retort Process is the most widely accepted method of sterilizing products using an over pressure process.
The Water Immersion process is similar to a saturated steam process in that the product is totally isolated from any influence
of cooling air, the product is totally submerged in water. But, it is different from Saturated Steam in that air can be introduced
into the vessel during sterilization. Overpressure is provided by introducing air (or steam) on top of the water. In some instances,
the air is added to the steam (which then heats the air). The heated air agitates the water as it flows to the surface and serves
to pressurize the processing load.Sterilization temperature max temperature 130 °C.Sterilization temperature adjustable.
Applicable scope:
1.Large flexible/soft package
2. Color/shape-sensitive products, such as sweet corn and sausage.
3. Flexible pouch serial： flexible retort pouches, laminated film bages, high-temperature cooking bages, vacuum bags
Advantages of Water Immersion Retorts:
●Hot water is stored in the upper tank, which can quickly fill the lower tank during sterilization, and the product heats up quickly.
●After sterilization, the sterilized water can be recycled to the upper tank, saving water resources and steam heat energy.
●The product is completely immersed in sterilizing water and does not come into contact with the air. There is no air cold mass in retort chamber,
and the temperature penetrates into the product in all directions, resulting in high sterilization efficiency.
●The hot water power circulation achieves the best heat distribution in the sterilization retort chamber and ensures the uniform sterilization effect of the product.
●The quality of the equipment is stable, using selected materials and high-quality spare parts, making it durable.
●The optimized design of the sealing structure is more durable and easy to maintain.
●Easy to operate and install, and the ergonomic design makes the machine safer and more comfortable.
●The appearance is beautiful, the pot body has basically no openings, and the pipes are concentrated at the rear of the equipment, which facilitates
the planning and design of the factory and saves floor space.
Working Principle of Water Immersion Retorts:
1. Preheat: Inject water into the upper tank, preheat water at the desired temperature.
2. Water down into the lower tank:
3. Sterilization: The circulation pump circulates the process water in the vessel and makes the products soaked totally in water, the process water keeps rising along with steam entering in the pipeline, and finally gets in under control at a desired temperature. The pressure is adjusted to the ideal range through boost valve and and vent valve.
4. Recycle: Pump the process water up to the upper tank.
5. Cooling: Cooling water starts entering in the retort and the products temperature keep reducing at a desired temperature.
6. Cooling water is pumped out, the pressure is released through vent.valve.
With separate manual panel
The manual panel is separated and not placed on the PLC screen to prevent manual operation after PLC is damaged. The upgraded manual panel also serves as a process flow chart, which is beautiful and elegant.
Why Sumpot Retort Machines?
Manufacturing process: excellent manufacturing process, keep improving, high processing precision requirements for each component to ensure the quality of the retort machine(industrial autoclave).
Heat distribution effect: GB39948 heat distribution national standard drafting unit, good heat distribution effto ensure the normal operation of the retort autoclaves.
Raw material procurement: select international first-class brand accessories, such as Siemens, Festo, etc., the equipment has high stability.
