Product Description

Product Description

Water immersion rotary retort uses the rotation of the rotating body to make the contents flow in the package, meanwhile drive the process water to improve the uniformity of the temperature in the retort. Hot water is prepared in advance in the hot water tank to start the sterilization process at high temperature and achieve the fast temperature rising, after sterilization, hot water is recycled and pumped back to hot water tank to achieve the purpose of energy saving.

Working Principle

Put the product into the sterilization retort, cylinders are individually compressed and close the door. The retort door is secured by triple safety interlocking. Throughout the whole process, the door is mechanically locked.

The sterilization process is automatically carried out according to the recipe input to the 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 ±0.5ºC, and pressure is controlled at 0.05 Bar.

During the whole process, the rotation speed and time of the rotating body are determined by the sterilization process of the product.

Detailed Photos

1. Spiral tube heat exchanger

DTS patented tube heat exchanger. Inside tube material is stainless steel 316L, no need to replace the rubber gasket, no need maintenance, corrosion resistance, long service life.

2. Safety interlock

Manual swing open door with safety interlock.
Option: Space-saving gullotine door with hydraulic driven.
Retorts have intrinsically safe door locking mechanisms with electrical switches interlocked with the internal vessel pressure.

3.Maintenance cycle and time alarm

For main valves, we set the maintenance cycle and time in the PLC, when it arrives, there will be alarm appear to notice.

4. Full automatic linear control system

DTS self-studied patented technology D-TOP system can be sensitive to temperature. It can automatically calculate the pressure changes inside the container according to the temperature. And then automatically adjust the pressure inside the retort to get the pressure balance between container internal and external. So it can prevent the package's deformation, keep the package shape. Pressure was controlled in + / - 0.05 bar with compressed air intake valve and exhaust valve.

5. Double pressure control

Two pressure sensors work at the same time, contrast each other, for real-time monitoring of pressure. When there is a failure, another work automatically, to ensure normal operation of equipment.

6.Heat distribution and Heat penetration (Optional)

Good heat distribution result is the basis of the retort, before using the retort for sterilizing the product, heat distribution must be carried out. And as for the product process, we need to do the heat penetration to find the exact sterilization process instead of cooking too much or less. It means we can find the F0 according to the logger's data. DTS has the loggers to do these tests, we bought from America TMI, we can send engineers for this service.

7. CNC machining centers

The use of special tooling and CNC machining centers, laser cutting and other equipment can ensure the accuracy of equipment processing to the greatest extent.
 

8. Dependable, reliable and robust design

Rotor is well fabricated on the positioning& assembly station, after welding, the complete rotor is processed in machine center and treated in high temperature to eliminate the internal stress caused by welding, which ensures the robust structure are extremely durable resulting in reduced wear and a long service life.

Our Advantages

1. 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.
2. 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.
3. Suitable for easily deformed containers
Because water has buoyancy, it can form a very good protective effect on the container when rotate.
4. 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.
5. The rotating system has a simple structure and stable performance
The rotating body structure is processed and formed at a time, and then balanced treatment is performed to ensure the stability of the rotation
The roller system uses an external mechanism as a whole for processing. The structure is simple, easy to maintain, and greatly extend the service life.
The pressing system adopts double-way cylinders to automatically divide and compact, and the guide structure is stressed to prolong the service life of the cylinder.
