2020 High quality Water Immersion Rotary Autoclave Retort - Water Immersion Retort – Dingtaisheng

Advantage

Uniform water flow distribution:

By switching the water flow direction in the retort vessel, uniform water flow is achieved at any position in the vertical and horizontal directions. An ideal system for dispersing water to the center of each product tray to achieve uniform sterilization without dead ends.

High temperature short time treatment:

High temperature short time sterilization can be performed by heating hot water in a hot water tank in advance and heating from high temperature to sterilize.

Suitable for easily deformed containers:

Because water has buoyancy, it can form a very good protective effect on the container under high temperature state.

Suitable for handling large packaging canned food:

It is difficult to heat and sterilize the central part of large canned food in a short time by using a stationary retort, especially for food with high viscosity.

By rotating, the high viscosity food can be evenly heated to the center in a short time, and achieve effective sterilization effect. The buoyancy of the water at high temperature also plays a role in protecting the product packaging during the rotating process.

Working principle

Load the full loaded basket into Retort, close the door. The retort door is locked through triple safety interlock to guarantee the safety. The door is mechanically locked throughout the whole process.

The sterilization process is automatically carried out according to the recipe of the input micro processing controller PLC.

At the beginning, the high-temperature water from the hot water tank is injected into the retort vessel. After the hot water is mixed with the product, it is circulated continuously through the large-flow water pump and the scientifically distributed water distribution pipe. Steam is injected through the water vapor mixer to make the product continue to heat up and sterilize.

The liquid flow switching device for retort vessel achieves uniform flow at any position in vertical and horizontal directions by switching the flow direction in the vessel, so as to achieve excellent heat distribution.

In the whole process, pressure inside the retort vessel is controlled by the program to inject or discharge air through the automatic valves to the vessel. Since it’s water immersion sterilization, pressure inside the vessel is not affected by temperature, and pressure can be set according to different packaging of different products, making the system more widely applicable（3 piece can, 2 piece can, flexible packages, plastic packages etc.）.

In the cooling step, hot water recovery and replacement can be selected to recover the sterilized hot water to the hot water tank, thus saving heat energy.

When the process is completed, an alarm signal will be issued. Open the door and unload, then prepare for the next batch.

The uniformity of temperature distribution in the vessel is ±0.5℃, and pressure is controlled at 0.05 Bar.
