Steam and rotary retort is to use the rotation of the rotating body to make the contents flow in the package. It is inherent in the process that all air be evacuated from the retort by flooding the vessel with steam and allowing the air to escape through vent valves.There is no overpressure during the sterilization phases of this process, since air is not permitted to enter the vessel at any time during any sterilization step. However, there may be air-overpressure applied during the cooling steps to prevent container deformation.
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. 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.

1. Accurate temperature control, excellent heat distribution
The temperature control module (D-TOP system) developed by DTS has up to 12 stages of temperature control, and the step or linearity can be selected according to different product and process recipe heating modes, so that the repeatability and stability between batches of products are maximized well, the temperature can be controlled within ±0.5ºC.
2. Perfect pressure control, suitable for a variety of packaging forms
The pressure control module (D-TOP system) developed by DTS continuously adjusts the pressure throughout the whole process to adapt the internal pressure changes of the product packaging, so that the degree of deformation of the product packaging is minimized, regardless of the rigid container of tin cans, aluminum cans or plastic bottles, plastic boxes or flexible containers can be easily satisfied, and the pressure can be controlled within ±0.05Bar.
3. Highly clean product packaging
The heat exchanger is used for indirect heating and cooling, so that the steam and cooling water are not in contact with the process water. The impurities in the steam and cooling water will not be brought to the sterilization retort, which avoids the secondary pollution of the product and does not require water treatment chemicals (No need to add chlorine), and the service life of the heat exchanger is also greatly extended.
DTS has experienced thermal verification experts and is a member of IFTPS in the United States. It fully cooperates with FDA-approved third-party thermal verification agencies. The experience of many North American customers has made DTS familiar with FDA/USDA regulatory requirements and cutting-edge sterilization technology.
4. Energy saving and envirnmental protection
A small amount of process water is quickly circulated to quickly reach the predetermined sterilization temperature.
Low noise, create a quiet and comfortable working environment.
Unlike pure steam sterilization, there is no need to vent before heating, which greatly saves steam loss and saves about 30% of steam.
