By adding a fan on the basis of steam sterilization, the heating medium and the packaged food are in direct contact and forced convection, and the presence of air in the sterilizer is allowed. The pressure can be controlled independently of the temperature. The sterilizer can set multiple stages according to different products of different packages.
1. Put the product into the sterilization retort and close the door. The retort door is secured by triple safety interlocking. Throughout the whole process, the door is mechanically locked.
2. The sterilization process is automatically carried out according to the recipe input to the micro-processing controller PLC.
3. This system is based on the direct heating for food packaging by steam, without other heating media (for example, the spray system is used water as an intermediate medium). Since the powerful fan forces the steam in the retort to form a cycle, the steam is uniform. Fans can accelerate the heat exchange between steam and food packaging.
4. Throughout the whole process, the pressure inside the retort is controlled by the program by feeding or discharging compressed air through the automatic valve to the retort. Due to steam and air mixed sterilization, the pressure in the retort is not affected by temperature, and the pressure can be set freely according to the packaging of different products, making the equipment more widely applicable (three-piece cans, two-piece cans, flexible packaging bags, glass bottles, plastic packaging etc.).
5. The uniformity of temperature distribution in the retort is +/-0.3ºC, and the pressure is controlled at 0.05Bar.
Spiral-tube heat exchanger
DTS self-studied and produced spiral heat exchanger, inside tube material is stainless steel 316, no need to replace the rubber gasket, no need maintenance, corrosion resistance, and have a long service life. DTS has patent of it in China.
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.
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.
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.
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 ±0.3ºC.
2.Rapid heating
No need to heat other media (such as hot water), the heating rate is very fast.
3. Perfect pressure control, sutable for a variety of packaging forms
The pressure control module (**** 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.
4. Compliant with FDA/USDA certificate
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.
5. Energy saving and environmrntal protection
The self-made high-quality spiral wound heat exchanger has high heat exchange efficiency and saves energy.
Low noise, create a quiet and comfortable working environment.
