[0040] The working principle of this utility model is as follows:
[0041] First, the wheat bran is crushed and added to the storage bin 2. Then, the DCS controller controls the auger conveyor 3 to transport the material from the storage bin 2 to the weighing cylinder 4. When the material in the weighing cylinder 4 reaches the maximum level, the auger conveyor 3 is turned off. The weight sensor 43 provides real-time feedback of the weight of the material in the weighing cylinder 4 to the controller. When it is necessary to add material to the mixing cylinder 5, the discharge valve 45 of the weighing cylinder 4 is opened. Then, the second motor 48 drives the rotating shaft 46 and the spiral blades 47 to rotate, causing the material in the weighing cylinder 4 to be discharged into the mixing cylinder 5 through the discharge pipe 52. The amount of material reduction in the weighing cylinder 4 is the amount of bran added to the mixing cylinder 5. After the material is added to the mixing cylinder 5, close the discharge valve 45 and the second motor 48. Then, open the sealing cover 50 and add an appropriate amount of water to the mixing cylinder 5 through the material addition port. Stir until it becomes a paste, adjust the pH value to a suitable range for protein hydrolysis, and then add protein through the material addition port to the mixing cylinder 5. By introducing hot water into the jacket cavity of the mixing cylinder 5, control the temperature of the protein in the mixing cylinder 5 to about 50°C and control the hydrolysis time for hydrolysis. Then, heat the liquid in the mixing cylinder 5 by introducing hot water into the jacket cavity of the mixing cylinder 5 to deactivate the enzyme. The resulting liquid is discharged through the discharge pipe 59 to the centrifuge for centrifugation and separation. Collect the protein in the supernatant to obtain protein with high purity.
