Load the product basket into the sterilization kettle. After the product is in place, the automatic cylinder is individually compressed, and the kettle door is closed. The kettle door is ensured to be safe through a triple safety interlock. Throughout the sterilization process, the kettle door is mechanically locked.
The sterilization process is automatically carried out according to the data input into the microprocessor controller PLC.
Inject hot water into the kettle through a hot water tank, empty the cold air inside the kettle, inject steam into the top of the equipment, and synchronize the steam intake and drainage to fill the space inside the kettle with steam. After all the hot water in the kettle is discharged, continue to heat up to the sterilization temperature. There is no cold spot during the entire heating and sterilization process. After reaching the sterilization time, start cooling with cooling water. During the cooling stage, control the pressure inside the kettle reasonably to ensure that the tank will not deform due to the pressure difference between the inside and outside.
During the heating and sterilization stages, the pressure inside the kettle is generated by the saturation pressure of steam. Generate back pressure during cooling to ensure that the product packaging does not deform.
The entire process of work, the rotational speed and time of the rotating body are determined by the product's manufacturing process.
Advantages of steam rotary sterilization kettle
● Uniform heat distribution
By eliminating the air inside the sterilization kettle, the purpose of saturated steam sterilization is achieved. Therefore, during the heating stage after exhausting the steam, the temperature inside the kettle reaches a very uniform state
● Compliant with FDA/USDA certification
DTS has experienced thermal validation experts and is a member of IFTPS in the United States. We fully cooperate with third-party thermal validation agencies recognized by the FDA, and the experience of numerous North American customers has made DTS familiar with FDA/USDA regulatory requirements and sterilization technologies.
● Simple and reliable
Compared to other forms of sterilization, there are no other heating media for the heating and sterilization stages, so it is only necessary to control the steam well to ensure the consistency of the batch of products. The FDA has provided detailed instructions on the design and operation of sterilization kettles, so customers are aware of the working principle of this type of sterilization kettle, making it easy for old users to accept.
The rotating system has a simple structure and stable performance
The rotating structure is processed and formed in one go, and then balanced to ensure the smoothness of the cage rotation.
The towing system adopts an external mechanism for overall processing, with a simple structure that is easy to maintain and greatly extends its service life.
The compression system adopts dual pneumatic cylinders for automatic segmented compression, guiding the structure to bear force and extending the service life of the cylinders.
