There are more than 600 corn starch production factories in China, with an annual output accounting for about 80% of the total starch output in the country, making it a veritable large corn starch production country in the world. With the development of processing technology, the corn starch production technology in China has developed rapidly, and the product quality and yield have been increasing year by year.

On the outer top plate of the fermentation tank 2, there is a feeding port 3. On the feeding port 3, there is a rotating cylinder 8. At the output end of the rotating cylinder 8, there is a top plate 21. The top plate 21 is lapped on the grinding plate inside the fermentation tank 2. On the grinding plate, there are protrusions 11. On the rotating cylinder 8, there is a premixing tank 4. Inside the premixing tank 4, there is a moving mechanism 19. On one side of the top of the premixing tank 4, there is a side plate 18. On the side plate 18, there is a blocking mechanism 20. The input port of the blocking mechanism 20 communicates with the reagent tank 14. First, place the required reagents into the reagent tank 14. After starting the equipment, put the corn into the rotating cylinder 8. The corn can move along the rotating cylinder 8 towards the grinding plate and the top plate 21. During the process of the servo motor 12 driving the rotating cylinder 8 to rotate, the cooperation between the top plate 21 and the grinding plate can grind and crush the corn kernels. After being crushed, they will be washed away by the solution and move away from the grinding plate. The crushed corn kernels will not accumulate on the grinding plate, thus ensuring that the crushing effect of the corn kernels remains unchanged. During the rotation of the rotating cylinder 8, the reagents will enter the premixing tank 4 in batches for pre-mixing. After mixing, discharging from the premixing tank 4 can quickly mix with the solution. The whole process realizes integrated operation, thereby improving production efficiency.

[0032] The rotating cylinder 8 is connected through the fermentation tank 2. A transmission belt 13 is sleeved on the rotating cylinder 8 outside the fermentation tank 2. The other end of the transmission belt 13 is sleeved on the output end of the servo motor 12. The feeding port 3 on the rotating cylinder 8 is integrally conical. The small port of the feeding port 3 is welded to the port of the rotating cylinder 8 outside the fermentation tank 2. Driven by the servo motor 12 through the rotating cylinder 8, during the rotation of the rotating cylinder 8, it can drive the top plate 21 and the stirring frame 16 to rotate. The top plate 21 can cooperate with the grinding seat for crushing, and the stirring frame 16 can stir and mix the reagents in the premixing tank 4.

[0033] The grinding plate is welded to the support rod 6. The support rod 6 is vertically installed at the bottom of the fermentation tank 2. On the side wall of the support rod 6, there is a bracket 5 welded. The other end of the bracket 5 is welded to the side wall of the premixing tank 4. The premixing tank 4 is integrally cylindrical. The rotating cylinder 8 is connected through the center position of the premixing tank 4. Through the setting of the grinding plate and the top plate 21, the entering corn kernels can be crushed, so that after the corn kernels are broken, they can be mixed with the solution in the fermentation tank 2 for fermentation.

[0034] During implementation, by arranging a rotary drum 8 inside the fermentation tank 2, the rotary drum 8 can achieve the circulation of corn. A top plate 21 is provided at the end of the rotary drum 8 of the fermentation tank 2. Inside the fermentation tank 2 below the top plate 21, there is a grinding plate. When the corn falls through the rotary drum 8, it can fall between the top plate 21 and the grinding plate. The rotary drum 8 is connected to the servo motor 12 through a transmission belt 13, and the servo motor 12 can drive the rotary drum 8 to rotate. When the rotary drum 8 rotates, it can drive the top plate 21 to crush and grind the corn on the grinding plate, and the corn will be crushed into small pieces, so there is no need to separately crush the corn. The chemical agent tank 14 can pre-store the used chemical agents, and the chemical agents will slide to the position of the connection box 203. When the corn is ground, the rotary drum 8 will rotate, and the push seat 205 on the rotary drum 8 will push the arc seat 206, and the arc seat 206 can drive the plug seat 204 to move. The flow channel on the plug seat 204 will move into the material pipe 201, and the material pipe 201 will not be blocked, and the chemical agents can fall through the material pipe 201 and thus fall into the premixing tank 4. As the rotary drum 8 rotates, the upper rod 195 and the lower rod 198 in the premixing tank 4 will reciprocate, and the solution can enter the premixing tank 4. The solution and the chemical agents can be stirred by the stirring frame 16, and the chemical agents can be quickly mixed. After the mixed liquid is discharged from the premixing tank 4, it can be quickly mixed with the solution. By setting up the whole process, it can be integrated operation, thus improving the production efficiency of corn protease hydrolysis.

[0035] The diameter of the top plate 21 is the same as that of the grinding plate. The top plate 21 is located above the grinding plate, and a placement space is formed between the top plate 21 and the grinding plate. Blades 9 are bolted to the side wall of the top plate 21, and the blades 9 are arranged in a circle around the outer wall of the top plate 21. A through hole 10 is opened on the top plate 21, and the through hole 10 communicates with the rotary drum 8. By arranging the blades 9 on the side wall of the top plate 21, the solution near the top plate 21 can be stirred, and after stirring, the solution can be mixed with the crushed corn kernels. During the stirring process of the blades 9, the solution will also fluctuate, which is conducive to washing the corn kernels on the grinding plate down.

[0036] A stirring frame 16 is provided on the rotary drum 8 inside the premixing tank 4. The stirring frame 16 is located at the bottom of the premixing tank 4. An inlet 15 is opened at the top of the premixing tank 4, and a movable mechanism 19 is connected inside the inlet 15. An upper frame 17 is arranged inside the premixing tank 4, and the upper frame 17 is arranged on the movable mechanism 19. The upper frame 17 is integrally arranged in a circular ring shape. By means of the stirring frame 16, stirring can be carried out in the space of the premixing tank 4, so that the solution and the chemical agents can be quickly mixed, thus improving the mixing efficiency of the solution and preventing the chemical agents from being insufficiently mixed when the solution in the premixing tank 4 is discharged.

[0037] The movable mechanism 19 includes a vertical rod 191. An upper frame 17 and a lower frame 196 are arranged on the vertical rod 191. An upper rod 195 is provided on the upper frame 17, and a scraper 194 is provided on the upper rod 195. A lower rod 198 is provided on the lower frame 196.

The height of the guide wheel 192 will be different when the rotating position of the guide groove 193 is different. The guide wheel 192 can drive the upper rod 195 and the lower rod 198 to move. When the upper rod 195 retracts into the premixing tank 4, the lower rod 198 extends out of the premixing tank 4. When the upper rod 195 extends out of the premixing tank 4, the lower rod 198 retracts into the premixing tank 4. The guide wheel 192 will be restricted and will not move independently away from the premixing tank 4, so as to ensure that the guide wheel 192 can move up and down normally when moving along the guide groove 193 and will not rotate.

[0039] The blocking mechanism 20 includes a material pipe 201. A connection box 203 is provided on the connecting pipe. A blocking seat 204 is slidably connected in the connection box 203.

A push seat 205 is lapped on the arc seat 206. The material pipe 201 can be divided through the connection box 203. When the blocking seat 204 is installed in the connection box 203, the blocking seat 204 can block the material pipe 201, and the medicament will not directly fall into the premixing tank 4. When the blocking seat 204 is connected to the arc seat 206, the arc seat 206 will be driven by the push of the push seat 205 to drive the blocking seat 204 to move, and the flow channel of the blocking seat 204 will communicate with the material pipe 201, and the medicament can fall into the premixing tank 4. When the push seat 205 moves away from the arc seat 206, the return spring 202 will push the blocking seat 204 in the reverse direction, and the blocking seat 204 can block the material pipe 201 again, so as to realize the batch discharge of the medicament.

The pushing seat 205 is integrally semi-circularly arranged, protruding from the rotating cylinder 8. The material pipe 201 communicates with the premixing tank 4. Through the pushing seat 205, the arc seat 206 can be pushed, so as to realize the movement of the arc seat 206.

[0041] As Figures 1 - 8 shown, a fermentation method of a corn protease hydrolysis fermentation device includes the following steps:

[0042] S1: Place the corn raw materials into the feeding port 3. The raw materials will fall into the placement space between the top plate 21 and the grinding plate. Place the medicaments to be used later into the medicament box 14. After starting the servo motor 12, the rotating cylinder 8 will be driven. During the driving process, the rotating cylinder 8 will drive the top plate 21 at the end to rotate. During the rotation of the top plate 21, the corn kernels will be ground and broken. The broken small-grain corn can be mixed with the solution in the fermentation tank 2. The blades 9 are installed on the side wall of the top plate 21. During the rotation of the top plate 21, the blades 9 will stir the solution at the position of the top plate 21, and the solution will fluctuate, and the crushed corn between the grinding plate and the top plate 21 can be washed away;

[0043] S2: After the crushed corn is washed away, it will be suspended around the grinding plate. With the continuous rotation of the top plate 21, the solution will be stirred through the blades 9. The washed-away corn can be quickly mixed with the solution, the protein in the corn can be fully released, and after being released and stirred, it can be quickly and evenly mixed, and the fermentation efficiency can be improved;

[0044] S3; During the rotation of the rotating cylinder 8, the arc seat 206 will be pushed by the pushing seat 205, and the arc seat 206 will move into the connecting box 203. The flow channel on the pushing seat 205 will reciprocally approach or move away from the material pipe 201. When approaching, it can be aligned with the material pipe 201, and the medicaments can be batch-fed into the premixing tank 4 through the material pipe 201. With the continuous rotation of the rotating cylinder 8, the guide wheel 192 will move up and down along the guide groove 193, and the upper rod 195 and the lower rod 198 will reciprocally extend or retract into the premixing tank 4. When the upper rod 195 retracts into the premixing tank 4, the lower rod 198 extends into the premixing tank 4, and the solution can enter the premixing tank 4. After being stirred by the stirring frame 16, it can be fully mixed. When the upper rod 195 extends out of the premixing tank 4 and the lower rod 198 retracts into the premixing tank 4, the solution mixed with the medicaments in the premixing tank 4 can be discharged from the premixing tank 4, so that the medicaments can be quickly mixed with the materials in the fermentation tank 2.

[0045] In implementation, by opening a guide groove 193 on the rotating cylinder 8 in the premixing tank 4, the guide groove 193 is opened around the outer periphery of the rotating cylinder 8, the guide groove 193 has a high end and a low end, when the guide wheel 192 moves along the guide groove 193, the height of the guide wheel 192 will change reciprocally. When the guide wheel 192 moves to the bottom end of the guide groove 193, the guide wheel 192 is close to the bottom of the premixing tank 4.

The upper rod 195 is arranged on the upper frame 17, the lower rod 198 is arranged on the lower frame 196. When the guide wheel 192 moves to the bottom end of the guide groove 193, the upper rod 195 retracts into the premixing tank 4, and the lower rod 198 extends out of the premixing tank 4. When the guide wheel 192 moves to the high end of the guide groove 193, the upper rod 195 extends out of the premixing tank 4, and the lower rod 198 retracts into the premixing tank 4. The solution in the fermentation tank 2 can enter the premixing tank 4 through the water inlet 15, and then be discharged from the premixing tank 4 through the drain port 197, so as to mix the medicament separately and then discharge it, thereby accelerating the mixing of the medicament and the solution.

[0046] The working principle of the present invention is as follows: By arranging a rotary drum 8 inside the fermentation tank 2, the rotary drum 8 can achieve the circulation of corn. A top plate 21 is provided at the end of the rotary drum 8 of the fermentation tank 2. Inside the fermentation tank 2 below the top plate 21, there is a grinding plate. When the corn falls through the rotary drum 8, it can fall between the top plate 21 and the grinding plate. The rotary drum 8 is connected to the servo motor 12 through a transmission belt 13. The servo motor 12 can drive the rotary drum 8 to rotate. When the rotary drum 8 rotates, it can drive the top plate 21 to crush and grind the corn on the grinding plate. The corn will be crushed into small pieces, and there is no need to crush the corn separately. The medicament tank 14 can pre-store the medicaments used.

The arc seat 206 can drive the plug seat 204 to move. The flow channel on the plug seat 204 will move into the material pipe 201, and the material pipe 201 will not be blocked. The medicaments can fall through the material pipe 201 and thus fall into the premixing tank 4. As the rotary drum 8 rotates, the upper rod 195 and the lower rod 198 in the premixing tank 4 will reciprocate. The solution can enter the premixing tank 4. The solution and the medicaments can be stirred by the stirring frame 16, and the medicaments can be quickly mixed. After the mixed liquid is discharged from the premixing tank 4, it can be quickly mixed with the solution. By setting up, the whole process can be operated integrally, thereby improving the production efficiency of corn protease hydrolysis. By opening a guide groove 193 on the rotary drum 8 in the premixing tank 4, the guide groove 193 is opened around the outer circumference of the rotary drum 8. The guide groove 193 has a high end and a low end. When the guide wheel 192 moves along the guide groove 193, the height of the guide wheel 192 will change reciprocally.
