[0002] Feed fermentation tanks play an important role in the feed processing industry, and improve the nutritional value of feed through specific fermentation processes. A feed fermentation tank is a device specifically used for feed fermentation. By controlling parameters such as temperature, humidity, and pH during the fermentation process, precise control of the fermentation process can be achieved to ensure the quality and effect of fermented feed.

[0003] However, the existing feed fermentation tanks have relatively single functions, low system integration, low automation, high manufacturing costs, high energy consumption, and deficiencies in controlling factors such as mixing efficiency, temperature, and pH. There are also defects of uneven mixing and complex operation during use and cleaning, and the residues that are not cleaned thoroughly will also affect the effect and quality of feed fermentation. At the same time, the bottom discharge tank may be blocked due to too large particle size of the raw materials, so it is necessary to design a new type of feed fermentation tank to improve the control accuracy of factors such as mixing efficiency, temperature, and pH, and at the same time maintain the smoothness of discharge to ensure the quality of materials. Summary of the Utility Model

At the same time, the PLC control system controls the pneumatic gate valve 36 to open and start feeding. When all the raw materials required at the front end are fed in, the pneumatic gate valve 36 is automatically closed.

[0039] The temperature sensor sends a signal to the PLC control system. When the temperature in the tank is lower than the temperature required for constant temperature fermentation, the indirect heating steam pneumatic valve is automatically opened, that is, the heat source is introduced into the indirect heating steam inlet 23 so that it enters the heating coil 15 to heat the stainless steel tank 1. When the temperature is higher than the temperature required for constant temperature fermentation, the indirect heating steam pneumatic valve is automatically closed. While the constant temperature fermentation is in progress, the dosing system is started to add the well-proportioned enzymolysis solution and the reagent into the fermentation enzymolysis tank; the pH sensor sends a signal to the PLC control system to control whether the reagent is added according to the real-time pH value.

[0040] After the constant temperature fermentation is completed, the direct heating pneumatic valve is opened, and the steam enters the steam nozzle 17 through the steam direct injection port 3 on the top of the tank and enters the tank to directly heat and raise the temperature. When the temperature reaches the required temperature, the steam direct injection pneumatic valve is automatically closed to stop heating.

Compared with a general fermentation tank, there are two ways to avoid various blockage problems of raw materials and can be completely emptied.
