Description

Technical Field

[0001] This invention relates to the technical field of food processing, and in particular to a pretreatment device for processing food raw materials. Background Technology

[0002] The food industry is an important pillar of the modern economic system, and its development level is directly related to people's well-being and consumption upgrading. As consumers' expectations for the taste, texture, flavor and nutritional value of food are increasing, the market demand for high-quality, diversified and stable food has increased significantly. Food crushing is a key pre-processing step in food processing. Its core objective is to refine, disperse or emulsify the solid particles in food raw materials so that the material system reaches a highly uniform and stable state.

[0003] Traditional processing methods typically use structures such as extrusion rollers and crushing hammers to directly crush raw materials. However, this method is relatively coarse, resulting in poor uniformity of material crushing and incomplete homogenization. Summary of the Invention

[0008] Furthermore, both the turntable and the outer ring are provided with a plurality of movable bodies that slide along the generatrix of the turntable and the outer ring, respectively. The two ends of the roller are rotatably connected to the corresponding movable bodies on the turntable and the outer ring, respectively. When the movable body moves, the gap width between two adjacent rollers changes.

[0009] Furthermore, each of the moving bodies on the turntable is provided with a rotating column; The chassis contains a vertically movable ring, which is coaxial with the turntable. The bottom of the ring has a groove, and the opening of any position on the groove is inclined towards the axis of the ring. The top of each rotating column is slidably inserted into the groove.

[0010] Furthermore, a rubber ring is provided on one side wall of the opening of the annular groove, and a compression ring is rotatably provided on the other side wall.

[0012] The beneficial effects of this invention are as follows: By employing multiple crushing and homogenization processes, the particle size of the raw materials can be gradually reduced until it meets the specified requirements, effectively improving the uniformity of the raw materials and enhancing the processing effect. Furthermore, by allowing only the raw materials that meet the requirements to be discharged from the equipment, the simultaneous screening of raw materials can be achieved, allowing the raw materials that do not meet the requirements to be continuously crushed until they meet the specified requirements.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 9 As shown, a pretreatment device for food raw material processing according to the present invention includes a housing 1, a feed pipe 2 installed on the top of the housing 1, and a turntable 3 and a turntable 4 located inside the housing 1. The feed pipe 2 is connected to the turntable 3 and is used to transport raw materials between the turntable 3 and the turntable 4. A plurality of rolling plates 5 are arranged between the turntable 3 and the turntable 4. The plurality of rolling plates 5 are arranged in a ring. The gap between two adjacent rolling plates 5 is used for material distribution. A plurality of rollers 6 are arranged on the outer side of the plurality of rolling plates 5, and a plurality of rollers 7 are arranged on the outer side of the plurality of rollers 6. Among them, the rolling plate 5 and the roller 1 6 work together to shear and homogenize the raw material, the roller 1 6 and the roller 2 7 work together to perform a first rolling and homogenizing process on the raw material, and the two adjacent rollers 2 7 work together to perform a second rolling and homogenizing process on the raw material. In this invention, the bottom of the casing 1 is conical, and a discharge port is opened at the lowest point of the cone. The raw material is fed into the casing 1 from the feed pipe 2 at the top of the casing 1 and discharged from the opening at the bottom of the casing 1. Turntable 1 3 and turntable 2 4 are distributed vertically inside the casing 1, and turntable 1 3 and turntable 2 4 are coaxial. The space between turntable 1 3 and turntable 2 4 is used for crushing the raw material. Between turntable 1 3 and turntable 2 4, a number of crushing plates 5, a number of rollers 1 6 and a number of rollers 2 7 are arranged in a ring from the inside to the outside. The crushing plates 5 can move in a circle around the axis of turntable 1 3, and the rollers 1 6 and rollers 2 7 can rotate. The width of the gap between crushing plates 5 and rollers 1 6, the gap between rollers 1 6 and rollers 2 7, and the gap between two adjacent rollers 2 7 gradually decreases. During raw material processing, the raw material is continuously introduced into the space between turntable 3 and turntable 4 through feed pipe 2. Turntable 3 and turntable 4 are rotated to make the raw material undergo centrifugal motion. The raw material spreads outward on turntable 4 and is discharged between the rolling plate 5 and roller 6 through the gap between two adjacent rolling plates 5. Due to the rotation of the rolling plate 5, the rolling plate 5 and roller 6 can cooperate to squeeze the raw material. At this time, the raw material is crushed by shear force, thereby achieving shear homogenization of the raw material. At the same time, since roller 6 can rotate, it can synchronously roll the raw material, reducing the particle size. When the raw material moves to the space between roller 6 and roller 7, roller 6 and roller 7 can roll and homogenize the raw material, reducing the particle size again. Then the raw material moves to the space between two adjacent rollers 7 and undergoes rolling and homogenization again. This achieves multiple crushing and homogenization of the raw material. After multiple treatments, the particle size of the raw material meets the specified requirements. At this time, the raw material is discharged through the bottom opening of the machine box 1. It should be noted that since the size of the gap between two adjacent rollers 7 is fixed, only raw materials that meet the particle size requirements are allowed to pass through, thereby achieving the screening of raw materials; in order to avoid the accumulation of raw materials on the roller 5, the surface of the roller 5 facing the axis of the turntable 3 can be set as a cone. With the help of centrifugal force, the raw materials can move on the cone towards the gap between two adjacent rollers 5. Of course, since the particle size of the raw materials is different when they are fed, when the raw materials move beyond the several rolling plates 5, the raw materials can automatically pass through the gap between the rolling plate 5 and roller 1 6, the gap between roller 1 6 and roller 2 7, or the gap between two adjacent rollers 2 7 according to their own particle size. That is, larger particles of raw materials cannot pass through smaller gaps, and they can only move towards the corresponding gap direction by means of the movement of the rolling plate 5, roller 1 6 and roller 2 7. By employing multiple crushing and homogenization processes, the particle size of the raw materials can be gradually reduced until it meets the specified requirements, effectively improving the uniformity of the raw materials and enhancing the processing effect. Furthermore, by allowing only the raw materials that meet the requirements to be discharged from the equipment, the simultaneous screening of raw materials can be achieved, allowing the raw materials that do not meet the requirements to be continuously crushed until they meet the specified requirements.

[0020] Furthermore, both turntable 3 and turntable 4 are conical, the axis of roller 7 is perpendicular to the outer surface of turntable 3 or turntable 4, and the shape of roller 7 is conical. By setting both turntable 3 and turntable 4 to be conical, the raw material can be easily diffused in all directions, thus preventing the raw material from accumulating on turntable 4 and clogging the feed pipe 2, improving the smoothness of the raw material movement, and thus ensuring that the equipment can process continuously. By setting the axis of roller 7 to be perpendicular to the outer surface of turntable 3 or turntable 4, the gap between the end of roller 7 and turntable 3 or turntable 4 can be reduced, preventing the raw material from entering the gap and hindering the normal rotation of roller 7. Of course, to further optimize this setting, the corresponding positions on turntable 3 and turntable 4 can be set to plane 14, so that the end face of roller 7 contacts plane 14, thereby further reducing the gap. Since roller 7 is inclined, in order to keep the gap width between two adjacent rollers 7 uniform, roller 7 can be set into a conical shape, which can improve the consistency of the discharged raw materials.

[0021] Furthermore, the turntable 2 4 includes an outer ring 8 located on the outer side, an inner ring 9 located inside the outer ring 8, and a middle plate 10 located inside the inner ring 9. The rolling plate 5 is rotatably mounted on the middle plate 10, the roller 1 6 is rotatably mounted on the inner ring 9, and the roller 2 7 is mounted on the outer ring 8. Among them, the outer ring 8 and the inner ring 9 are relatively fixed, the inner ring 9 and the middle plate 10 rotate relative to each other, and the outer ring 8 and the turntable 3 are connected by several connecting rods 11. By using a combination, the middle plate 10 can move relative to the outer ring 8 and the inner ring 9, thereby facilitating the rotation of the rolling plate 5 relative to the roller 6 or the roller 7. The upper surfaces of the outer ring 8, the inner ring 9 and the middle plate 10 are coplanar, allowing the raw material to move smoothly on them. The connecting rod 11 can be used to connect the turntable 3 and the outer ring 8, so that the turntable 3, the outer ring 8 and the inner ring 9 can move synchronously or remain stationary. The raw material passing through the gap between two adjacent rollers 7 can be discharged through the space between two adjacent connecting rods 11.

[0022] Furthermore, a plurality of pusher plates 12 are provided on the middle plate 10; the shape of the pusher plate 12 is arc-shaped, flat, or other shapes. The pusher plate 12 is installed at an angle on the middle plate 10, and one end of the pusher plate 12 is located in the middle of the middle plate 10. When the middle plate 10 rotates, the raw material falling on the middle plate 10 can be pushed outward by the plurality of pusher plates 12, thereby facilitating the diffusion of the raw material and improving the centrifugal effect of the raw material.

[0023] Furthermore, both turntable 3 and outer ring 8 are provided with several movable bodies 13 that slide along the corresponding generatrix of turntable 3 and the corresponding generatrix of outer ring 8. The two ends of roller 7 are rotatably connected to the corresponding movable bodies 13 on turntable 3 and outer ring 8, respectively. When the movable body 13 moves, the gap width between two adjacent rollers 7 changes. When processing different raw materials or processing the same raw material into different specifications, it is necessary to adjust the gap between two adjacent rollers 7 to facilitate the adjustment of the raw material particle size. The adjustment of the gap between two adjacent rollers 7 can be achieved by adjusting the distance between roller 7 and the axis of turntable 3. That is, when several rollers 7 spread outwards, the width of the gap between two adjacent rollers 7 will change, and the width of each gap remains equal. The moving body 13 is mainly used to support and guide the rollers 7; for example... Figure 6 As shown, a groove is made on the outer wall of the circumference of turntable 3 or the outer wall of the circumference of turntable 4. A movable body 13 is slidably arranged in the groove. The movable body 13 and the groove are used to guide the sliding direction of roller 7. In some embodiments, the movement of roller 2 7 can be in addition to the linear movement described above, it can also be arc-shaped, spiral, or inclined. As long as the distance between roller 2 7 and the axis of turntable 3 can be changed, the gap width between two adjacent rollers 2 7 can be adjusted.

[0024] Furthermore, each movable body 13 on turntable 3 is equipped with a rotating column 15; The chassis 1 is equipped with a vertically movable ring 16. The ring 16 is coaxial with the turntable 4. The bottom of the ring 16 is provided with a ring groove 17. The opening direction of any position on the ring groove 17 is inclined towards the axis of the ring 16. The top of each rotating column 15 is slidably inserted into the ring groove 17. Since the opening direction of the annular groove 17 is inclined at any position, that is, the annular groove 17 is conical, when the annular groove 17 moves in the vertical direction, the annular groove 17 can use its own shape characteristics to push the rotating column 15 to move. The rotating column 15 can push the moving body 13 and the roller 7 to move. Since the moving body 13 moves along the generatrix direction of the corresponding turntable 3 or turntable 4, in the horizontal direction, the annular groove 17 will push the roller 7 closer to or away from the axis of turntable 3. In the vertical direction, the rotating column 15 will slide towards the inside of the annular groove 17 or move towards the outside of the annular groove 17. Thus, the position adjustment of several rollers 7 can be achieved by using the movement of the ring 16. Moreover, this adjustment method is simple and the synchronization of the adjustment of several rollers 7 is high.

[0025] Furthermore, a rubber ring 18 is provided on one side wall of the opening position of the annular groove 17, and a compression ring 19 is rotatably provided on the other side wall. Both the rubber ring 18 and the compression ring 19 are in contact with the outer wall of the rotating column 15. One of the two adjacent rotating columns 15 is connected to the corresponding roller 7 via a transmission, and the other rotating column 15 rotates on the corresponding moving body 13; When turntable 3 rotates, it drives several rotating columns 15 to move within the annular groove 17. At this time, the rotating columns 15 roll on the rubber ring 18, causing them to rotate. The rotating columns 15, which are connected to the rollers 7, drive the rollers 7 to rotate. However, the adjacent rollers 7 cannot receive the transmission from their corresponding rotating columns 15. Therefore, one of the two adjacent rollers 7 acts as the active source. When processing the raw material, the active roller 7 squeezes and conveys the material, while the adjacent rollers 7... The rotation is automatic, and the two adjacent rollers 7 rotate relative to each other. This setting is to prevent the material from entering the gap between the two adjacent rollers 7 when they rotate synchronously and in the same direction. When the rotating column 15 rotates, it will drive the extrusion ring 19 to rotate on the ring 16, thereby ensuring that the connecting rod 11 and the extrusion ring 19 can move and play a clamping effect on the rotating column 15, avoiding the gap between the rotating column 15 and the rubber ring 18 or the extrusion ring 19 and causing the rotating column 15 to have a movement gap in the ring groove 17. It should be noted that when the rolling plate 5 is used in conjunction with roller 6 or roller 6 is used in conjunction with roller 7 to process the raw materials, roller 6 mainly performs driven motion.

[0026] Furthermore, the ring 16 is provided with several top plates 20, and the top plates 20 are provided with threaded grooves. Threaded wheels 21 are fitted in the threaded grooves. A telescopic rod 22 is provided on the top of the threaded wheel 21. The telescopic rod 22 passes through the housing 1 and is rotatably connected to each other. A handwheel 23 is provided on the top of the telescopic rod 22. The handwheel 23 is connected to the housing 1 by a spring 24. The handwheel 23 has several slots on its outer wall, and the chassis 1 has a card plate 25 that works in conjunction with the slots. Spring 24 provides elastic tension to handwheel 23, thus keeping telescopic rod 22 in a retracted state. At this time, locking plate 25 engages in a slot on handwheel 23, preventing handwheel 23 from rotating. Threaded wheel 21 and threaded groove on top plate 20 cannot move relative to each other, thus locking the height position of ring 16. When the position of ring 16 needs to be adjusted, handwheel 23 can be lifted to separate handwheel 23 from locking plate 25. Then, handwheel 23 can be rotated, using threaded wheel 21 and threaded groove on top plate 20 to push top plate 20 up and down, thereby adjusting the gap between adjacent rollers 27. Several top plates 20 are arranged in a ring on ring 16, thus achieving a guiding effect on ring 16. To provide rotational power to turntable 3 and turntable 4, such as Figure 1As shown, a motor 28 is installed on the casing 1. A bevel gear 29 is installed at the output end of the motor 28. A bevel gear 30 meshes with the bevel gear 29 and is installed on the feed pipe 2. Thus, the motor 28 provides rotational power to the feed pipe 2, the turntable 3, and the turntable 4. Since the feed pipe 2 rotates, it is difficult to feed materials. Therefore, a sleeve 26 can be fitted on the feed pipe 2 and the sleeve 26 can rotate relative to the feed pipe 2. The sleeve 26 is fixed to the casing 1 by several support arms 27. Thus, materials can be directly fed into the sleeve 26, allowing the raw materials to enter the feed pipe 2 naturally. To enable the middle plate 10 to rotate, transmission rings 31 are provided at the bottom of both the inner ring 9 and the middle plate 10. Several transmission wheels 32 are installed between the two transmission rings 31. The transmission wheels 32 are mounted on the inner wall of the machine box 1 via support rods 33. When the inner ring 9 rotates with the turntable 3, the inner ring 9 will drive the middle plate 10 to rotate synchronously and in opposite directions through the two transmission rings 31 and the transmission wheels 32, thereby causing the rolling plate 5 to move relative to the roller 6.

[0027] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
