Description

Technical Field

[0002] In the field of edible vegetable oil processing, especially in the industrial production of corn oil, the crushing process during the raw material pretreatment stage is crucial. Corn kernels must be efficiently crushed into uniform and fine particles to improve the oil yield and oil quality in the subsequent pressing process.

[0003] Existing technologies generally use a double-roller milling device, which uses high-speed rotating milling rollers to apply compression and shear forces to corn kernels to achieve crushing. However, because corn kernels are rich in oil, the crushed kernels are easily adhered to the milling rollers during the crushing process due to oil seepage. This adhered kernels hinder effective contact between the milling rollers and the raw material, reducing crushing uniformity. This can lead to some kernels being repeatedly crushed or not fully crushed, affecting the consistency of the raw material in the subsequent pressing process. Therefore, we propose a milling device for edible vegetable oil processing. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Figure 8 The core of the pulverizing device for processing edible vegetable oil shown in the figure is to solve the problems of reduced efficiency and equipment loss caused by oil adhesion in the process of corn particle crushing through structural optimization and functional coordination. The device is supported by a main frame 1 as a whole, and a crushing box 2 and a stripping box 26 with upper and lower layers are fixed inside the main frame 1. A feed hopper 27 is provided on the top of the stripping box 26 for feeding corn on the cob. The stripping roller 28 in the stripping box 26 is driven by an external stripping motor 29 and rotated by a pulley structure. After the corn particles are peeled off from the corn cob, they fall into the crushing box 2 below through the bottom opening. Two high-speed rotating crushing rollers 3 are symmetrically arranged in the crushing box 2. The surface of the crushing roller 3 is designed with staggered serrated protrusions to enhance the shear force. One end of the crushing roller 3 is connected to the main shaft 4, and the main shaft 4 is driven by the crushing motor 5 through a pulley to realize the reverse rotation of the two rollers, thereby squeezing and crushing the falling corn particles. In order to solve the problem of particles adhering to the crushing roller 3 and the inner wall of the box after crushing, the device integrates a dynamic cleaning system. The system includes a cleaning module 6, a power transmission component 11 and a motion component 12. The core of the cleaning module 6 is the air jet 7 and the air collecting cylinder 8. The air jet 7 is arranged horizontally in the crushing box 2, and a plurality of nozzles 9 are evenly distributed on its outer wall. Furthermore, the nozzle 9 can choose a convergent-divergent nozzle 9. The ratio of the throat diameter of the nozzle 9 to the outlet diameter is controlled between 1:3 and 1:5 (not shown in the drawings). The fan 16 in the air collecting cylinder 8 pumps high-pressure air into the air jet 7. The air flow is accelerated by the nozzle 9 to form a supersonic jet, which directly impacts the surface of the crushing roller 3. The spray direction of the nozzle 9 is at an angle of 15°-30° to the surface of the crushing roller 3 (not shown in the drawings), ensuring that the air flow can effectively peel off the adhered particles and avoid excessive wear on the crushing roller 3. A mesh plate 25 is provided at one end of the air collecting cylinder 8 to filter impurities in the inhaled air. The other end is connected to the air jet 7 through the air pipe 10 to form a closed air flow cycle. Among them, the power transmission component 11 synchronously transmits the rotational power of the main shaft 4 of the crushing roller 3 to the cleaning module 6. Specifically, the first driving wheel 13 is fixed on the main shaft 4, and the first driven wheel 14 on the rotating shaft of the fan 16 in the air collecting cylinder 8 is driven by the first belt 15, so that the fan 16 runs synchronously with the crushing roller 3, ensuring that the air flow supply matches the crushing rhythm. In addition, the rotating shaft of the fan 16 extends to the outside of the crushing box 2, and transmits power to the auxiliary shaft 32 through the bevel gear set. Specifically, the first bevel gear 30 fixed on the rotating shaft of the fan 16 drives the second bevel gear 31 provided on the outside of the crushing box 2 to rotate through the meshing action, thereby driving the auxiliary shaft 32 to rotate. Since the turntable 18 is fixed at the top of the auxiliary shaft 32, and the turntable 18 is provided with an eccentric shaft 19, the eccentric shaft 19 is hinged to the sleeve 17 on the outside of the air injection pipe 7 through the connecting rod 20 and the linkage rod 21. When the turntable 18 rotates with the auxiliary shaft 32, the circular motion of the eccentric shaft 19 is converted into a linear reciprocating motion of the air jet pipe 7 along the fixed rail 22, i.e., the axial direction of the crushing roller 3, via the connecting rod 20 and the linkage rod 21, so that the jet from the nozzle 9 covers the entire surface of the crushing roller 3, avoiding blind spots in cleaning. Furthermore, the bottom of the crushing chamber 2 is designed as a conical structure, with symmetrically distributed arc-shaped protrusions 23 on its inner wall. The bottom of the sleeve 17 of the air injection tube 7 is connected to a polyurethane elastic rod 24, the end of which is equipped with a rubber hammer 33, which fits against the inner wall of the cone. As the air injection tube 7 reciprocates, the elastic rod 24 moves with the sleeve 17. As it passes over the arc-shaped protrusions 23, the deformation generates a periodic elastic force, which drives the rubber hammer 33 to strike the inner wall of the chamber, triggering high-frequency vibrations, further shaking off particles adhering to the inner wall of the crushing chamber 2. The conical bottom also has a discharge port, through which the crushed particles are discharged in a concentrated manner through vibration guidance for the subsequent pressing process.

[0022] The implementation steps of this technical solution are as follows: S1. Feed corn cobs into a stripping box 26 through a feed hopper 27. A stripping motor 29 drives stripping rollers 28 to rotate at high speed via a pulley structure. The corn cobs are rubbed and squeezed between the rollers, causing corn kernels to be stripped from the cobs. The stripped corn kernels then naturally fall through the bottom opening of the stripping box 26 into the crushing box 2 below. S2, the grinding motor 5 drives the main shaft 4 to rotate through the pulley structure, driving the two symmetrically arranged grinding rollers 3 to rotate in opposite directions at a high speed with adjustable speed. After the corn particles fall into the gap between the grinding rollers 3, they are captured by the staggered serrated protrusions on the surface and crushed into fine particles through extrusion and shear force. During the crushing process, the corn particles will partially adhere to the surface of the grinding rollers 3 and the inner wall of the grinding box 2 due to their oil content; S3. When the main shaft 4 rotates, the first driving wheel 13 fixed thereon drives the first driven wheel 14 to rotate through the first belt 15, thereby driving the rotating shaft of the fan 16 in the air collecting cylinder 8, so that the fan 16 runs synchronously. The fan 16 draws air from the outside, filters impurities through the mesh plate 25 in the air collecting cylinder 8, and then the high-pressure airflow is transported to the air injection pipe 7 through the air pipe 10. The nozzle 9 on the air injection pipe 7 accelerates the airflow, impacts the surface of the crushing roller 3, and peels off the adhered particles; The rotating shaft of the fan 16 is engaged with the first bevel gear 30 and the second bevel gear 31 of the bevel gear set to drive the auxiliary shaft 32 to rotate. The turntable 18 at the top of the auxiliary shaft 32 drives the eccentric shaft 19 to make a circular motion. The eccentric shaft 19 drives one end of the connecting rod 20 to make a circular motion. The other end of the connecting rod 20 drives the linkage rod 21, the sleeve 17 and the air injection pipe 7 to reciprocate along the direction of the fixed rail 22, thereby converting the circular motion of the turntable 18 into a linear reciprocating motion of the air injection pipe 7 along the axial direction of the crushing roller 3. The stroke range covers the entire length of the crushing roller 3. During this process, the nozzle 9 moves with the air injection pipe 7, and the high-speed airflow evenly covers the surface of the crushing roller 3 to prevent the accumulation of adhesion; S4. The polyurethane elastic rod 24 at the bottom of the sleeve 17 of the air jet tube 7 has a rubber hammer head 33 at the end, which moves with the air jet tube 7. When passing through the arc-shaped protrusion 23 on the conical inner wall of the crushing box 2, the elastic rod 24 deforms and rebounds, driving the hammer head to strike the inner wall at high frequency. The vibration energy is transmitted to the inner wall of the crushing box 2, causing the adhered particles to detach and fall. The crushed particles are guided by the conical bottom and assisted by vibration to be collected at the discharge port and enter the subsequent pressing process.

[0023] Example 2: This embodiment further illustrates Example 1. Figure 6 and Figure 7 As shown, the difference lies in the optimization of the connection between the gas collecting cylinder 8 and the gas pipe 10; Specifically, the connection between the air collecting cylinder 8 and the air duct 10 is a tapered structure that gradually shrinks from the air collecting cylinder 8 to the air duct 10. The design of the tapered structure allows the fan 16 to smoothly press the air into the air duct 10, thereby improving the gas transmission efficiency.

[0024] Example 3: This embodiment further illustrates Example 1. Figure 6 As shown, the difference lies in the optimization of the airway 10; Specifically, the middle section of the air pipe 10 is a spring telescopic tube; the design of the spring telescopic tube allows the air pipe 10 to adapt to the reciprocating motion of the air jet pipe 7, reducing the stretching or squeezing of the air pipe 10, extending its service life, and reducing the possibility of the tube body itself twisting and tangling.
