Description

Technical Field

[0001] This utility model relates to the field of crushing and emulsification technology, and in particular to a crushing and emulsification device for soybean raw materials used in soybean milk production. Background Technology

[0002] In the soy milk production process, the crushing and emulsification of soybeans are crucial steps, directly affecting the taste, nutrient release, and product stability of the soy milk. Traditional crushing and emulsification devices typically employ a single-stage crushing structure, meaning that the soybeans are crushed only once before directly entering the emulsification stage. In existing equipment, the screens are mostly fixed, and the material is pushed through the screen by a single crushing action inside the crushing chamber. Due to differences in soybean varieties or pretreatment levels, some substandard coarse residues tend to adhere to the screen surface or accumulate in the dead corners at the bottom of the crushing chamber, failing to make effective contact with the blades. This causes these residues to remain for a long time, which not only prevents further crushing but may also clog the screen channels, reducing material flow efficiency. Ultimately, the finished soy milk still contains obvious coarse residues, affecting the taste. Usually, the machine needs to be stopped to discharge the retained coarse residues and repeat the secondary crushing, which is not conducive to the continuous crushing of soybeans and thus affects the continuity of soybean crushing. Utility Model Content

This device can solve the problem that the screens of the existing devices are mostly fixed and rely solely on a single crushing action inside the crushing chamber to push the material through the screen. Due to differences in soybean varieties or pretreatment levels, some substandard coarse residues easily adhere to the screen surface or accumulate in the dead corners at the bottom of the crushing chamber, failing to form effective contact with the blades. This causes these residues to remain for a long time, which not only prevents further crushing but may also clog the screen channels, reduce material flow efficiency, and ultimately result in the finished soybean milk still containing obvious coarse residues, affecting the taste. Usually, it is necessary to stop the machine and discharge the retained coarse residues for secondary crushing, which is not convenient for continuous crushing of soybeans and thus affects the continuity of soybean crushing.

The top is equipped with a feed hopper 8, the side is equipped with a control panel 6 and a discharge pipe 17, and the discharge cavity 11 is opened to accommodate and support each component to complete the crushing process. Conveyor motor 2: Installed on the side of soybean crushing box 1 away from conveyor cylinder 9, with the output end connected to conical spiral auger 13. After starting, it drives the spiral auger to rotate, providing power for conveying coarse residue. Gears 3: There are two in total, which are fixed to one end of the two rotating shafts 4 that extend out of the crushing box. They mesh with each other and can transmit the power of the drive motor 5 to the other rotating shaft 4 to achieve synchronous rotation of the two shafts in opposite directions. Rotating shaft 4: Both shafts are rotatably connected inside the soybean crushing box 1. The crushing blade 18 is fixed on the outer surface. When driven, it rotates, causing the crushing blade 18 to shear and crush the soybeans. Drive motor 5: mounted on support plate 7, with a rotating shaft 4 connected to its output end. After starting, it drives the shaft to rotate and is the power source for crushing soybeans. Control panel 6: Installed on one side of soybean crushing box 1, it can independently control the operation of each grade structure and realize the control of crushing, reflux and other processes; Support plate 7: Fixed on the side of the soybean crushing box 1 near the gear 3, used to support the installation of the drive motor 5 and ensure stable operation of the motor; Feed hopper 8: Bolted to the top of soybean crushing box 1, used to feed pre-treated soybeans, and connected to the discharge end of conveyor cylinder 9 to receive the return coarse residue; Conveying cylinder 9: Installed on the side of soybean crushing box 1 near the discharge pipe 17, containing conveying screw 15, with the inlet end connected to the discharge pipe 17 and the outlet end connected to the feed hopper 8, used to convey coarse residue to the feed hopper 8. Stepper motor 10: mounted on the top of conveying cylinder 9, with its output end connected to conveying screw 15. After starting, it drives the screw to rotate, providing power for conveying coarse residue in conveying cylinder 9. Feeding cavity 11: It is located inside the soybean crushing box 1, below the arc-shaped filter plate 12, and is connected to the filter holes of the filter plate. It is used to receive and discharge qualified fine particles and slurry. Arc-shaped filter plate 12: fixed inside the soybean crushing box 1, with filter holes and conical cavity 19. The filter holes screen qualified materials, and the conical cavity 19 accumulates coarse residue. Conical spiral auger 13: Located inside the conical cavity 19, one end is connected to the conveyor motor 2, and the other end is connected to the positioning plate 14. When rotating, it pushes the coarse residue to the discharge pipe 17. Positioning plate 14: Fixed inside the discharge pipe 17, used to rotate and support the end of the conical spiral auger 13 away from the motor, ensuring its stable rotation; Conveying screw 15: It is connected to the conveying cylinder 9 and the output end of the stepper motor 10. When it rotates, it uses the screw lifting force to send the coarse residue from the feed end to the discharge end. Guide plates 16: Two of them are fixed on the inner wall of the soybean crushing box 1 and above the rotating shaft 4. They can accurately guide the raw materials to the crushing area between the two rotating shafts 4 to prevent them from scattering. Discharge pipe 17: Fixed on one side of soybean crushing box 1 and internally connected, with a positioning plate 14 inside, connected to the feed end of conveying cylinder 9, used to convey coarse residue to conveying cylinder 9; Multiple crushing blades 18 are fixed on the outer surface of the two rotating shafts 4 and rotate at high speed with the shafts to shear and crush soybeans by impact. Conical cavity 19: It is opened inside the arc-shaped filter plate 12 and is used to accumulate coarse residue that has not passed through the filter holes, so as to facilitate the conveying of the conical spiral auger 13.

[0020] Example 1: like Figure 1-4 As shown, coarse residue that does not pass through the filter holes of the arc-shaped filter plate 12 accumulates in the conical area on the surface of the arc-shaped filter plate 12 due to its arc-shaped structure. At this time, by starting the conveyor motor 2, its output end drives the conical spiral auger 13 to rotate. The rotation of the conical spiral auger 13 pushes the coarse residue in the conical cavity 19 along the spiral blades to the discharge pipe 17. Since the feed end of the conveyor cylinder 9 is connected to the inside of the discharge pipe 17, after the coarse residue enters the conveyor cylinder 9, the stepper motor 10 is started, and its output end drives the conveyor screw 15 to rotate. The conveyor screw 15 uses the spiral lift to transport the coarse residue from the feed end of the conveyor cylinder 9 to the discharge end. The discharge end of the conveyor cylinder 9 is connected to the inside of the feed hopper 8, finally realizing the return of the coarse residue to the feed hopper 8, completing the closed loop of "residue and feed".

[0021] Example 2: like Figure 4 As shown, the conical cavity 19 inside the arc-shaped filter plate 12 further assists in the aggregation of coarse residues by the inclination angle of the inner wall of the conical cavity 19, preventing the residues from scattering to non-preset areas or adhering to the edge of the arc-shaped filter plate 12 during the accumulation process, completely eliminating the situation of coarse residues accumulating in the dead corner at the bottom of the soybean crushing box 1, and ensuring that the coarse residues are always concentrated in the treatable area inside the conical cavity 19.

[0022] Furthermore, when using the device, the operator puts the pre-treated soybean raw material into the feed hopper 8. The raw material falls down along the feed hopper 8 into the soybean crushing box 1. At this time, the two guide plates 16 fixed on the inner wall of the soybean crushing box 1 play a guiding role, accurately guiding the raw material to the crushing area between the two rotating shafts 4, avoiding the raw material from falling into the dead corner of the crushing chamber, and ensuring crushing efficiency.

[0023] When the drive motor 5 is started, its output end drives a fixed rotating shaft 4 to rotate synchronously. Since the two gears 3 mesh with each other, when one rotating shaft 4 rotates, it will drive the other rotating shaft 4 to rotate synchronously in the opposite direction through the meshing transmission of the gears 3. As the two rotating shafts 4 rotate, the multiple crushing blades 18 fixed on their outer surfaces rotate at high speed, shearing and impact crushing the soybean raw material guided by the guide plate 16, crushing the soybeans into a solid-liquid mixture containing fine particles and a small amount of coarse residue.

[0024] The crushed mixture falls onto the surface of the arc-shaped filter plate 12 under gravity. The filter holes of the arc-shaped filter plate 12 only allow fine particles and slurry of the preset particle size to pass through. After passing through the filter holes, the qualified fine particles and slurry enter the discharge cavity 11 opened inside the soybean crushing box 1 and are discharged. This qualified material is then transported to the subsequent emulsification process to complete the preliminary crushing pretreatment.

[0025] Coarse residue that does not pass through the filter holes of the arc-shaped filter plate 12 accumulates in the conical area on the surface of the arc-shaped filter plate 12 due to its arc-shaped structure. At this time, the conveyor motor 2 is started and its output end drives the conical spiral auger 13 to rotate. The rotation of the conical spiral auger 13 pushes the coarse residue in the conical cavity 19 along the spiral blades to the discharge pipe 17. Since the feed end of the conveyor cylinder 9 is connected to the inside of the discharge pipe 17, after the coarse residue enters the conveyor cylinder 9, the stepper motor 10 is started and its output end drives the conveyor screw 15 to rotate. The conveyor screw 15 uses the spiral lift to transport the coarse residue from the feed end of the conveyor cylinder 9 to the discharge end. The discharge end of the conveyor cylinder 9 is connected to the inside of the feed hopper 8, finally realizing the return of the coarse residue to the feed hopper 8, completing the "residue-feed" closed loop.

[0026] The coarse residue that flows back to the feed hopper 8 enters the crushing area between the two rotating shafts 4 along the guide plate 16 again, and is crushed again by the crushing blade 18 together with the newly added soybean raw material. The above-mentioned "crushing, separation, recirculation and re-crushing" process can be repeated until the coarse residue completely meets the particle size requirements and passes through the arc-shaped filter plate 12, ultimately achieving efficient crushing of all soybean raw materials.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
