Water immersion retort uses the unique liquid flow switching technology to improve the uniformity of temperature inside the retort vessel. 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.

1. Spiral tube heat exchanger
DTS self studied and produced heat exchanger, inside tube material is stainless steel 316L, no need to replace the rubber gasket, no need maintenance, corrosion resistance, long service life. DTS has patent of it in China.
2.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. Especially suitable for aluminum tray products. Pressure was controlled in + / - 0.05 bar with compressed air intake valve and exhaust valve.
3. 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.
4.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.
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 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.
1. How to install and maintain the machine?
The retort will be tested at the factory, and will try to ship without disassembly. All pipeline have number and identification, as shown in the attached picture. Also, we will provide remote service system, through which our engineers can guide and train in real time.
2. Are you a factory or a trader?
DTS is one of the most influential suppliers for food and beverage sterilization manufacturing industry in Asia. We have highly experienced and talent mechanical engineers, design engineers and electrical software development engineers to provide the best products and services as well as excellent working environment for our customers
3. What shall we do if breakdown occurs?
Please inform us once the breakdown occurs. During warranty period, if breakdown occurs, we shall respond in time after receiving the notification of the buyer. We shall handle failure over the telephone/real time video according to the buyer's requirements.
