[0022] First, the present invention is provided with a fermentation tank, a tank cover, a turntable, a bimetallic strip, a telescopic rod, an arc-shaped sliding rheostat, a spiral tube and an electric heating tube. In the initial stage of fermentation, the fermentation temperature is kept stable at about 30 to 35 degrees. At this time, the bimetallic strip does not bend, the turntable remains stationary, the resistance value of the arc-shaped sliding rheostat remains unchanged, and the electric heating tube heats the water in the water tank to keep a constant temperature, and continuously enters the movable tube and the spiral tube to keep the fermented material warm.

At this time, the bimetallic strip is also heated to drive the turntable to rotate forward, and the resistance value of the arc-shaped sliding rheostat increases to reduce the temperature in the water tank, so that the water flowing through the movable rod and the spiral tube The temperature is lowered for appropriate cooling treatment, and the alkaline solution in the liquid storage chamber 1 enters the fermentation tank for appropriate pH adjustment. In the late stage of fermentation, the temperature of the fermented product drops and needs to be heated, and the pH value increases and needs to be appropriately lowered. The bimetallic strip is bent in reverse due to the cold to drive the turntable to rotate in the opposite direction, and the acidic solution in the liquid storage chamber 2 enters the fermentation tank for appropriate pH adjustment. The resistance of the arc sliding rheostat decreases, and the temperature in the water tank increases to appropriately increase the fermentation of the fermentation product in the fermentation tank, thereby ensuring the stability of the fermentation of snail flavor peptides.

[0053] Working principle: When preparing the snail flavor peptide by fermentation, the snail meat to be fermented is inoculated with activated bacteria and sent into the fermentation tank 1. In the initial stage of fermentation, microorganisms begin to grow and their metabolic activity is weak. The temperature needs to be controlled between 30 and 35 degrees, and the pH value is relatively stable. At this time, the bimetallic strip 20 at the bottom of the turntable 19 remains horizontal and does not deform. The circuit composed of the power supply 5, the electric heating tube 8, the arc-shaped sliding rheostat 27, the sliding contact 28 and the controller has a constant resistance value of the arc-shaped sliding rheostat 27, a constant current flowing through the electric heating tube 8, and a stable pressure on the water tank 7. The water in the tank is heated to keep it at 30 to 35 degrees. The pump body 6 sends the water into the movable tube 31 through the water inlet pipe 3 and the support pipe 13, and then it is divided into two parts through the diversion hole. One part flows downward through the inside of the movable tube 31, and the other part enters the spiral tube 32 and spirals down, and then returns to the movable tube 31. Finally, they all return to the water tank 7 through the reflux pipe 9. When it reaches the middle stage of fermentation, the metabolic activity of microorganisms is enhanced, a large amount of organic acid is produced, and the temperature rises and needs to be cooled. The bimetallic strip 20 is heated to drive the turntable 19 to cooperate with the rotating shaft 26 to rotate forward, and the telescopic rod 23 The arc sliding rheostat 27 is appropriately contracted, the resistance value on the arc sliding rheostat 27 increases, the current flowing through the electric heating tube 8 decreases, the temperature in the water tank 7 decreases, the temperature of the water entering the movable tube 31 and the spiral tube 32 decreases, and the appropriate cooling treatment is performed. When the turntable 19 rotates, the liquid inlet hole 24 is aligned with the liquid inlet tube 29 at the position of the liquid storage chamber 15 in the liquid storage tank 14. The alkaline solution stored in the liquid storage chamber 15 passes through the turntable 19 and enters the fermentation tank 1 to adjust the pH value of the fermented product. In the later stage of fermentation, the metabolic activity of the microorganisms gradually weakens, and the pH value rises. The temperature is high, and gradually decreases and needs to be heated. The bimetallic strip 20 is cooled and drives the turntable 19 to cooperate with the rotating shaft 26 to rotate in the opposite direction. The liquid inlet hole 25 on the turntable 19 is aligned with the liquid inlet pipe 29 at the position of the liquid storage chamber 16. The acidic solution inside the liquid storage chamber 16 enters the fermentation tank 1 to adjust the pH value, and the resistance value on the arc sliding rheostat 27 decreases, the current flowing through the electric heating tube 8 increases, the temperature of the water in the water tank 7 increases, and the water flows through the movable tube 31 and the spiral tube 32 to appropriately heat the fermentation tank 1 to ensure that the fermentation environment is always suitable and stable.

[0054] A motor 4 is arranged on one side of the tank cover 2, and the motor 4 drives the bevel gear 21 to rotate through the rotating rod 17, and the meshing bevel gear 12 drives the support tube 13 and the movable tube 31 to rotate. The rotating movable tube 31 and the spiral tube 32 are in contact with the fermentation product more evenly and thoroughly, and the temperature is adjusted more accurately to avoid local overheating. The fermentation stirring frame 34 installed on the outer wall of the movable tube 31 rotates accordingly to perform appropriate stirring treatment on the fermentation product. The rotation speed of the rotating rod 17 is controlled according to the stirring requirements of different stages. When the rotating rod 17 rotates, it also drives the stirring blade 18 to rotate, and stirs the alkaline solution and the acidic solution stored in the liquid storage chamber 1 15 and the liquid storage chamber 2 16 in the liquid storage tank 14 to prevent precipitation stratification from affecting the adjustment of pH value.

[0055] A receiving tray 11 is fixedly arranged on the top of the movable tube 31, and a discharge hole 33 is opened on one side of the receiving tray 11. The alkaline solution or acidic solution flowing out of the liquid inlet hole 1 24 and the liquid inlet hole 2 25 falls into the continuously rotating receiving tray 11. The receiving tray 11 keeps rotating, and the acidic solution or alkaline solution flowing out of the discharge hole 33 is evenly sprinkled inside the fermentation tank 1, further improving the uniformity and accuracy of pH value adjustment.
