Soybean products are rich in plant protein, but different from meat, soybean products do not contain cholesterol, which is a kind of food that people like very much, such as three high, fat and so on. Steam sterilization is not an option for high-temperature sterilization of dried bean curd, because when steam sterilization is carried out, the taste of dried bean curd is relatively loose, which will become similar to the taste of bean curd residue, affecting sales. Water bath type sterilization pot should be selected for sterilization of dried bean curd. The taste of dried bean curd will not change after being stored for a long time.
The semi-automatic computer adopts PLC and text display to process the collected pressure sensor signal and temperature signal, which can store sterilization process with high control precision and temperature control up to ± 1 ℃. The cooling process is manually operated (mainly controlling air supply, exhaust, temperature and time).
The whole process of the computer automatic control type is controlled by PLC and touch screen, which can store the sterilization process. The operator only needs to press the start button, and the automatic alarm will be given after sterilization. The temperature control accuracy can reach ± 0.5 ℃. (the whole sterilization process has been digitized and mechanized) basically achieved one finger pass. (remove the incoming and outgoing goods and open and close the boiler door
