Product features:
Saturated steam sterilization kettle is the earliest type of sterilization kettle used in cans. Compared with iron pot sterilization, it is the simplest and most reliable type of sterilization kettle. In this process, the sterilization kettle is filled with steam and all the air is discharged from the sterilization kettle through the exhaust valve.
Since air is not allowed to enter the sterilization kettle at any time during any sterilization step, there is no overpressure during the sterilization stage of this process.
However, air overpressure may be applied during the cooling step to prevent the vessel from deforming.
FDA and Chinese regulations have made detailed regulations on the design and operation of steam sterilization kettle, so although it is not advantageous in terms of energy consumption, but because it is widely used in many old canneries, it is still favored by many customers.
DTS has been optimized in terms of automation and energy savings while ensuring compliance with FDA and USDA requirements.
The working principle of saturated steam sterilization kettle
Put the product in a basket into the sterilization kettle and the kettle door is closed.
Then the cauldron door is secured through triple safety interlock.
The door is mechanically locked throughout the sterilization process.
The sterilization process is carried out automatically according to the formula of the microprocessing controller PLC.
At the beginning, the steam enters into the steam through the steam diffusion pipe in the kettle, and the air is discharged through the exhaust port. When the exhaust temperature and time are reached, the heating stage is entered. The whole process of heating and sterilization should ensure that the sterilization kettle is saturated steam, and there can be no residual air to make the heat distribution uneven and sterilization incomplete.
The vent is opened in the whole exhaust, heating, sterilization stage, so that the steam can form convection, to ensure the uniformity of temperature.
There are two stages of cooling, micro cooling and total cooling. The purpose of micro cooling is not to lose pressure in the kettle and ensure that the product packaging is not deformed.
Because of the use of saturated steam when sterilization, sterilization kettle pressure and steam saturation pressure corresponding, only suitable for iron cans and other rigid vessels with a wide range of pressure requirements.
The temperature distribution uniformity in the kettle is +/-0.5℃.
The advantages of saturated steam sterilization kettle
● Uniform heat distribution
By eliminating the air in the sterilization kettle, the purpose of saturated steam sterilization is achieved, so the temperature in the heating stage after the discharge of steam reaches a very uniform state.
● Meets FDA/USDA certification
DTS has experienced thermal verification specialists, is a member of IFTPS in the United States, and fully cooperates with FDA-approved third-party thermal verification agencies. With the experience of many North American customers, DTS is familiar with FDA/USDA regulatory requirements and the most cutting-edge sterilization technology.
● Simple and reliable
Compared with other forms of sterilization, there is no other heating medium for the heating and sterilization stages, so only the control of steam can make the consistency of batch products good.
FDA has made a detailed description of the design and operation of steam sterilization kettle, and many old canneries have been applied, so customers are clear about the working principle of this type of sterilization kettle, so that this type of sterilization kettle is easy to accept by old users.
