Description

Technical Field

[0001] This utility model relates to the field of food grinding technology, specifically to a food raw material grinding device. Background Technology

[0002] Food ingredients refer to natural or processed substances used in food processing or for direct consumption. They can be derived from plants and animals, or from minerals or microbial fermentation products. A food ingredient grinding device is a device used to grind food ingredients such as grains, beans, spices, nuts, and Chinese medicinal herbs into fine particles or powder.

[0003] A food raw material grinding device is described in the existing patent document with authorization announcement number CN220310509U. The described solution includes a mirrored rejection component, which removes the material adhering to the grinding roller without affecting the operation of the grinding device. It also has a mirrored discharge port and a mirrored opening and closing component at the bottom of the box, which can load material through two discharge ports at the same time. The opening and closing component can be used to open and close the discharge port to facilitate material leakage when changing the loading equipment.

[0004] The above-mentioned technology has the problem of uneven feeding. If the amount of raw material fed varies, the grinding device cannot maintain stable shearing and extrusion pressure, resulting in inconsistent powder particle size. Some areas may be over-ground while other areas may be under-ground, leading to large fluctuations in the fineness of the final product. In addition, the above-mentioned technology also has the problem of not being able to adjust the spacing between the grinding rollers. If the spacing is too large, the material cannot be ground sufficiently, resulting in larger product particles that affect subsequent processing. If the spacing is too small, it may lead to over-grinding of food raw materials. Utility Model Content

Detailed Implementation

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] In one embodiment, such as Figures 1-6 As shown, a food ingredient grinding device includes a grinding chamber 100; a first filter plate 200 is provided inside the grinding chamber 100, and a second filter plate 300 is also provided inside the grinding chamber 100, with the second filter plate 300 slidably connected to the top of the first filter plate 200; it also includes a feeding component for feeding food ingredients into the grinding chamber 100; the feeding component includes a storage bin 401 located in the upper part of the grinding chamber 100, a discharge cylinder 402 located at the bottom of the storage bin 401, a servo motor 403 located on one outer wall of the discharge cylinder 402, a distributing cylinder 404 located at the output end of the servo motor 403, the distributing cylinder 404 being rotatably connected to the inside of the discharge cylinder 402 and matching the internal dimensions of the discharge cylinder 402, a plurality of distributing grooves 405 being opened on the distributing cylinder 404, and slots matching the shape and specifications of the distributing grooves 405 being opened at the top and bottom of the discharge cylinder 402; the grinding chamber 100 interior... A grinding assembly for grinding food raw materials is provided. The grinding assembly is located below the discharge cylinder 402 and above the second filter plate 300. An adjustment assembly for adjusting the second filter plate 300 is provided on the first filter plate 200. A vibration assembly for vibrating the first filter plate 200 is provided at the bottom of the first filter plate 200. A dust suction assembly for absorbing dust generated during grinding is also provided on the grinding box 100. By adding food raw materials into the storage bin 401, and then starting the servo motor 403, the dispensing cylinder 404 is rotated. When the dispensing trough 405 rotates to the slot at the top of the discharge cylinder 402, the food raw materials fall into the dispensing trough 405. As the dispensing cylinder 404 continues to rotate, when the dispensing trough 405 containing food raw materials reaches the slot at the bottom of the discharge cylinder 402, the food raw materials will fall into the grinding box 100 under the action of gravity.

[0029] like Figure 1 and Figure 2As shown, the grinding assembly includes a first grinding roller 501, which is rotatably connected inside the grinding chamber 100. The first grinding roller 501 rotates with the inner wall of the grinding chamber 100 through a shaft hole. Support columns 502 are provided through both side walls of the grinding chamber 100. A second grinding roller 503 is rotatably connected to the side of the two support columns 502 that are close to each other. The second grinding roller 503 is parallel to the first grinding roller 501 and also parallel to the discharge cylinder 402. Support plates 504 are symmetrically provided on one outer wall of the grinding chamber 100. Rotating shafts 505 are provided inside the two support plates 504. First bevel gears 506 are provided at both ends of the rotating shafts 505. The output shaft of the servo motor 403 passes through the dispensing cylinder 404, the discharge cylinder 402, and the grinding chamber 100 in sequence and extends to the outside. One end of the first grinding roller 501 passes through and extends... Outside the grinding chamber 100, the output shaft of the servo motor 403 and the first grinding roller 501 are both connected to second bevel gears 507, and the two second bevel gears 507 mesh with the two first bevel gears 506 respectively. Inside the grinding chamber 100, there is a moving component for moving the support column 502. The rotation of the servo motor 403 will not only drive the dispensing cylinder 404 to rotate, but also drive one of the second bevel gears 507 to rotate, thereby driving one of the first bevel gears 506 and the rotating shaft 505 to rotate, and then drive the other first bevel gear 506 and the second bevel gear 507 to rotate, thereby driving the first grinding roller 501 to rotate. The second grinding roller 503 will passively rotate by contact with the material and the friction of the first grinding roller 501, thereby grinding the food raw materials.

[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, the moving component includes slide grooves 601 respectively opened on both sides of the grinding box 100, and two support columns 502 are slidably connected in the two slide grooves 601 respectively. The side wall of the grinding box 100 is rotatably provided with threaded rods 602 corresponding to the two slide grooves 601. The two threaded rods 602 extend into the corresponding slide grooves 601 and are threadedly connected to the support columns 502. The end of the threaded rod 602 is provided with a turntable. By rotating the turntable, the threaded rod 602 is driven to rotate, thereby driving the support column 502 to slide inside the slide groove 601.

[0031] In one embodiment, such as Figure 3 and Figure 6As shown, the adjustment assembly includes two locking bolts 701 that are threaded to both ends of the bottom of the first filter plate 200. The bottom of the second filter plate 300 has several threaded holes 702 that are threaded to the locking bolts 701 on both sides. The bottom of the second filter plate 300 has several limiting blocks 703 on both sides. The top of the first filter plate 200 has several limiting grooves that are slidably connected to the limiting blocks 703. By rotating the locking bolts 701, they are moved away from the threaded holes 702, so that the second filter plate 300 can slide on the top of the first filter plate 200. The movement of the second filter plate 300 will also cause the limiting blocks 703 to slide in the limiting grooves. The limiting blocks 703 can prevent the second filter plate 300 from detaching from the first filter plate 200.

[0032] In one embodiment, such as Figure 3 and Figure 5 As shown, the vibration assembly includes a vibration motor 803 disposed at the bottom of the first filter plate 200. Several fixing plates 801 are respectively disposed around the bottom wall of the grinding box 100. A spring 802 is connected between the bottom of the first filter plate 200 and the top of the fixing plate 801. By starting the vibration motor 803, the first filter plate 200 is vibrated, and then the first filter plate 200 is reciprocated under the action of the spring 802.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the dust collection assembly includes a vacuum cleaner 901 disposed on the outer wall of the grinding box 100. The vacuum cleaner 901 is located in the upper middle part of the grinding box 100. The input end of the vacuum cleaner 901 extends into the interior of the grinding box 100 and is connected to the dust filter bag 902. By starting the vacuum cleaner 901, it sucks the dust generated during grinding into the dust filter bag 902.

[0034] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a side outlet is provided on one side of the grinding box 100 near the bottom, and a discharge port is provided at the bottom of the grinding box 100. The first filter plate 200 and the second filter plate 300 are both arranged at an angle, with the lower ends of the first filter plate 200 and the second filter plate 300 extending out from the side outlet, and the upper ends of the first filter plate 200 and the second filter plate 300 connected to the inner wall of the grinding box 100. Unground food raw materials can be discharged through the side outlet, and ground food raw materials can be discharged through the discharge port. The angled arrangement of the first filter plate 200 and the second filter plate 300 facilitates the discharge of unground raw materials.

[0035] In one embodiment, such as Figure 2As shown, guide plates 101 are provided at both ends inside the grinding box 100 to guide the raw materials falling into the grinding box 100 to the space between the first grinding roller 501 and the second grinding roller 503.

[0036] The working principle of this utility model is as follows: Food raw materials are added into the storage bin 401. The grinding degree required for different raw materials is then adjusted by rotating a turntable, which drives the threaded rod 602 to rotate, thereby moving the support column 502 within the sliding groove 601. This changes the distance between the second grinding roller 503 and the first grinding roller 501. Then, the locking bolt 701 is rotated away from the threaded hole 702, allowing the second filter plate 300 to slide on top of the first filter plate 200. After adjustment, the locking bolt 701 is rotated again, moving it closer to the threaded hole 702, thus changing the overlapping area of ​​the filter holes on the first filter plate 200 and the second filter plate 300, thereby changing the size of the sieve holes to accommodate different grinding degrees. Then, the servo motor 403 is started, driving the dispensing cylinder 404 to rotate. When the dispensing trough 405 rotates to the opening at the top of the discharge cylinder 402, the food raw materials fall into the dispensing trough 405. As the dispensing cylinder 404 continues to rotate, when the raw materials contain… When the food raw material distribution trough 405 reaches the bottom opening of the discharge cylinder 402, the food raw material will fall into the grinding box 100 under the action of gravity. The rotation of the servo motor 403 will not only drive the distribution cylinder 404 to rotate, achieving uniform material distribution, but the servo motor 403 will also drive a second bevel gear 507 to rotate, thereby driving a first bevel gear 506 and a rotating shaft 505 to rotate, and then drive another first bevel gear 506 and another second bevel gear 507, thereby driving the first grinding roller 501 to rotate. The second grinding roller 503 will passively rotate by contact with the material and the friction of the first grinding roller 501, thereby grinding the food raw material. Then, the vibration motor 803 is started to vibrate the first filter plate 200. Then, under the action of the spring 802, the first filter plate 200 will bounce back and forth, thereby screening the raw material. The vacuum cleaner 901 can also be moved to suck the dust generated during grinding into the dust bag 902.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
