Description

Technical Field

[0001] This utility model relates to the field of dried bean curd production technology, specifically to a grinding machine for dried bean curd production. Background Technology

[0002] Soy products, as an important part of my country's traditional food culture, are loved by consumers for their rich nutrition and unique flavor. Among them, dried tofu occupies an important position in the market due to its firm texture, easy storage, and diverse ways of consumption. The production process of dried tofu covers multiple stages, including raw material selection, soaking, grinding, pulp separation, boiling, coagulation, and pressing. Among these, grinding and pulp separation are the key steps that determine the quality of dried tofu. The fineness of grinding and the thoroughness of pulp separation directly affect the taste, nutritional value, and production efficiency of dried tofu. Therefore, efficient and stable grinding equipment is crucial for the large-scale production of dried tofu.

[0003] Currently, the grinding machines used in tofu production typically consist of two parts: a grinding device and a residue-slurry separation device. The working process is roughly as follows: Pre-treated soybeans and an appropriate amount of water are fed into the grinding tank of the grinding device. The soybeans are ground by a motor-driven grinding component (such as a grinding roller), breaking them down and mixing them with water to form a residue-slurry mixture. This mixture is then conveyed to the residue-slurry separation device (such as a separation cylinder with filter holes). Through natural filtration or agitation, the soy milk flows through the filter holes into a collection container, while the soybean residue remains in the separation cylinder, completing the initial residue-slurry separation. The separated soy milk then enters the subsequent processing stage. However, existing grinding machines have certain limitations in the residue-slurry separation stage: the agitation amplitude of the separation cylinder is fixed and cannot be adjusted according to the actual situation of the residue-slurry mixture. When the residue concentration is high or the soybean residue particles are large, the fixed agitation amplitude is insufficient to fully promote the flow of the mixture, easily leading to soybean residue clogging the filter holes and affecting the separation efficiency. Therefore, we propose a grinding machine for tofu production. Utility Model Content

The upper left side of the housing 1 is provided with a slot 26, a turntable 27, and a lever 28. The device includes an adjustable slider 24 and a rocking mechanism 2, which also includes a slide block 23. The slide block 23 is located on the upper side of the housing 1. The lower end of the slider 24 is slidably connected to the inside of the slide block 23. A screw 15 is rotatably connected between the left and right inner walls of the slide block 23. The screw 15 is threadedly connected to the lower end of the slider 24 (corrugated tubes are provided between the left and right sides of the lower end of the slider 24 and the left and right inner walls of the slide block 23, and the screw 15 is located inside the corrugated tubes. The corrugated tubes provide external protection for the screw 15 and ensure the lubrication and sealing of the screw 15). A motor 16 is mounted on the left side of the slide block 23. The output shaft of the motor 16 is fixedly connected to the left end face of the screw 15. The input end of the motor 16 is electrically connected to the output end of the control switch group 19. A support rod 2 is fixedly connected to the front side of the slider 24. 5. The front end of the support rod 25 is located inside the strip-shaped opening 22. The connecting rod 29 is rotatably connected to the left end of the swing rod 21 via the pin 7. The lower end of the connecting rod 29 is fitted with the upper end of the slurry separation cylinder 12. An avoidance groove 9 is provided on the left side wall of the casing 1. A sliding column 10 is provided between the upper and lower inner walls of the avoidance groove 9. The outer arc surface of the sliding column 10 is slidably connected to the drive rod 8. The lower right end of the drive rod 8 is fixedly connected to the upper side of the slurry separation cylinder 12. The left end of the drive rod 8 is rotatably connected to the lower end of the connecting rod 29. The operator puts the pre-treated soybeans and water into the feed pipe on the upper side wall of the grinding tank 3. The motor 6 is started by the control switch group 19. The output shaft of the motor 6 drives the rotating column and the conical grinding roller 4 at the lower end to rotate. The soybeans are ground by the conical grinding roller 4 inside the grinding tank 3. The slurry mixture produced during grinding enters the discharge pipe 5 through the outlet at the lower end of the outer arc wall of the grinding tank 3. At this time, the control switch group 19 controls the electric valve 14 on the discharge pipe 5 to open. The slurry mixture is collected by the workers through the discharge pipe 5. Then, the locking and transfer door are opened respectively, the plug is unscrewed, and the slurry mixture is poured into the slurry separation cylinder 12 through the slurry inlet pipe. Then, the plug is screwed back into the slurry inlet pipe, and the control switch group 19 starts the motor 18. The output shaft of the motor 18 drives the rotating shaft and the front turntable 27 to rotate. The deflector 28 at the right end of the front side of the turntable 27 moves in a circular motion with the turntable 27. The deflector 28 is located in the deflector groove 26 at the right end of the swing rod 21. Its circular motion is converted into the reciprocating swing of the right end of the swing rod 21.The slot 22 in the middle of the swing rod 21 is fitted onto the support rod 25, and the support rod 25 is fixed to the slider 24. To adjust the swing amplitude of the swing rod 21, the motor 16 is started by controlling the switch group 19. The motor 16 drives the screw 15 to rotate, and the slider 24, which is threadedly connected to the screw 15, slides left and right within the slide block 23, changing the position of the support rod 25 within the slot 22, thereby adjusting the swing amplitude of the left end of the swing rod 21. When the support rod 25 moves away from the left end of the swing rod 21, the swing rod... As the swing amplitude of the left end of the swing rod 21 increases, when the support rod 25 approaches the left end of the swing rod 21, the swing amplitude of the left end of the swing rod 21 decreases. The left end of the swing rod 21 drives the connecting rod 29 to move through the pin 7. The lower end of the connecting rod 29 is rotatably connected to the left end of the drive rod 8, thereby driving the drive rod 8 to move. The drive rod 8 is sleeved on the sliding column 10 in the clearance groove 9, and its right end is fixedly connected to the slurry separation cylinder 12. When the drive rod 8 slides up and down along the sliding column 10 under the drive of the connecting rod 29, the slurry... The separating cylinder 12 moves up and down synchronously within the sliding hole of the soy milk collection tank 11, causing the internal residue-slurry mixture to shake. Soy milk enters the soy milk collection tank 11 through the filter holes on the lower side wall of the separating cylinder 12, while the soy residue remains inside the separating cylinder 12. After a period of time, the electric valve 14 on the soy milk discharge pipe 13 is opened via the control switch group 19, allowing the soy milk to be discharged and collected through the discharge pipe 13. After separation, the relevant equipment is turned off, the transfer door on the upper side wall of the casing 1 is opened, and the plug is unscrewed. An external suction pump, through its hose and pump head, cleans the remaining soy residue inside the separating cylinder 12. (The external suction pump's suction port is connected to a hose, and the hose's suction port has a pump head. The external suction pump uses negative pressure to clean the remaining soy residue inside the separating cylinder 12 through the pump head and hose.) This adjustable shaking separation mechanism improves the grinding efficiency and residue-slurry separation effect in tofu production.

[0023] The working principle of the soybean grinding machine for dried bean curd production provided by this utility model is as follows: In the process of dried bean curd production, grinding is an important step. The operator puts pre-treated soybeans and water into the feed pipe on the upper side wall of the grinding tank 3. The motor 6 is started by the control switch group 19. The output shaft of the motor 6 drives the rotating column and the conical grinding roller 4 at the lower end to rotate. The soybeans are ground into a slurry mixture inside the grinding tank 3 by the conical grinding roller 4. The slurry mixture produced by grinding enters the discharge pipe 5 through the discharge port at the lower end of the outer arc wall of the grinding tank 3. At this time, the control switch group 19 controls the electric valve 14 on the discharge pipe 5 to open. The slurry mixture is collected by the worker through the discharge pipe 5, and then... Open the locking and transfer door respectively, unscrew the plug, and then pour the slurry mixture into the slurry separator 12 through the slurry inlet pipe. Next, screw the plug back into the slurry inlet pipe. Control switch group 19 starts motor 18. The output shaft of motor 18 drives the rotating shaft and the front turntable 27 to rotate. The right-side pivot 28 on the front side of turntable 27 moves in a circular motion with turntable 27. Pivot 28 is located in the slot 26 on the right end of swing rod 21, and its circular motion is converted into the reciprocating swing of the right end of swing rod 21. The strip-shaped opening 22 in the middle of swing rod 21 is fitted onto support rod 25, which is fixed to slider 24. To adjust the swing amplitude of swing rod 21, control switch group 19 starts motor 18. The control switch assembly 19 starts the motor 16, which drives the screw 15 to rotate. The slider 24, which is threadedly connected to the screw 15, slides left and right within the slide block 23, changing the position of the support rod 25 within the strip opening 22, thereby adjusting the swing amplitude of the left end of the swing rod 21. When the support rod 25 moves away from the left end of the swing rod 21, the swing amplitude of the left end of the swing rod 21 increases; when the support rod 25 moves closer to the left end of the swing rod 21, the swing amplitude of the left end of the swing rod 21 decreases. The left end of the swing rod 21 drives the connecting rod 29 to move through the pin 7. The lower end of the connecting rod 29 is rotatably connected to the left end of the drive rod 8, thereby driving the drive rod 8 to move. The drive rod 8 is sleeved on the sliding column 10 within the clearance groove 9, and its right end is connected to the slurry. The separator 12 is fixedly connected. When the drive rod 8 slides up and down along the slide column 10 under the drive of the connecting rod 29, the slurry separator 12 moves up and down in the sliding hole of the soy milk collection tank 11, causing the slurry mixture inside to shake. The soy milk enters the soy milk collection tank 11 through the filter hole on the lower side wall of the separator 12, while the soy residue remains in the separator 12. After a period of time, the electric valve 14 on the soy milk discharge pipe 13 is opened by the control switch group 19, and the soy milk is discharged and collected through the soy milk discharge pipe 13. After the separation is completed, the relevant equipment is turned off, the transfer door on the upper side wall of the casing 1 is opened, the plug is unscrewed, and the soy residue remaining inside the slurry separator 12 is cleaned.

[0024] It is worth noting that the motor 6 disclosed in the above embodiments can be a YE2 series three-phase asynchronous motor, the electric valve 14 can be a matching electric valve according to the pipe diameter of the discharge pipe 5 and the soy milk discharge pipe 13, the motor 16 can be a 57BYGH series stepper motor, the electric motor 18 can be a YS series three-phase asynchronous motor, and the control switch group 19 is provided with control buttons that correspond one-to-one with the motor 6, the electric valve 14, the motor 16 and the electric motor 18 and are used to control their switching.
