Technical Field

[0001] The invention belongs to the technical field of puffed food processing, and in particular relates to a powder grinding system for puffed food processing. Background Art

[0002] Puffed food is a new type of food that has been developed internationally in recent years. Made from grains, beans, potatoes, and vegetables, it is processed through puffing equipment to create a wide variety of exquisitely presented, nutritious, crispy, and delicious foods. The production of puffed food requires mixing, lifting, extrusion, deslagging, frying, seasoning, and packaging. The process involves grinding rice into powder and then mixing the ingredients together to create the food.

[0003] Patent No. CN109382168B discloses a rice grinding system for puffed food processing, comprising a grinding device and a bottom auxiliary grinding device, with the bottom auxiliary grinding device being mounted on the left side of the lower end of the grinding device. This invention can solve the problems encountered in existing puffed food processing, such as the need to grind rice into powder and then mix the ingredients, the difficulty of uniformly grinding rice with existing equipment, the uneven particle size, damage to the machine during grinding, the tendency of existing equipment to constantly vibrate during grinding, low work efficiency, high labor intensity, and long working time. This invention can automatically process rice into powder, automatically grind the rice into powder, grind the powder evenly without damaging the machine, and stabilize the workbench to ensure that there is no vibration during grinding, thereby improving work efficiency, reducing labor intensity, and shortening the working time.

[0004] In the prior art, the auxiliary grinding device can automatically grind the material into powder, thereby improving the efficiency. However, the following problems still exist during the use of the whole: First, the existing equipment will process the material into a size that can be ground into powder before grinding. However, some of the raw materials will roll during grinding, resulting in uneven grinding and uneven sizes, which affects the quality of the powder. Secondly, the existing grinding device grinds the raw materials into powder by rolling and colliding them. However, the raw materials themselves contain a certain amount of moisture.

[0018] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0019] refer to Figure 1 、 Figure 2 、 Figure 3and Figure 4 A grinding system for puffed food processing includes a grinding chamber 10, an end surface of the grinding chamber 10 is provided with a feed port 11, through which the raw materials to be ground can be added to the grinding chamber 10, a transmission rod 22 is provided for rotation inside the grinding chamber 10, one end of the transmission rod 22 is provided with a first motor on the end surface of the grinding chamber 10, the output end of the first motor is fixedly connected to the transmission rod 22, a bottom end of the transmission rod 22 is provided with a grinding disc 13 inside the grinding chamber 10, a grinding ring 15 is provided on the outer circumference of the grinding disc 13 on the inner wall of the grinding chamber 10, and a grinding ring 15 is provided on the inner wall of the grinding ring 15. Groove 18, the grinding groove 18 is connected with the grinding disc 13 in a sliding manner, and the grinding groove 18 and the grinding disc 13 are combined to form a V-shaped groove 19. When grinding the raw materials, the raw materials are first added to the interior of the grinding chamber 10 through the feed port 11, and then the first motor is started. The output shaft of the first motor will drive the transmission rod 22 to rotate, and the transmission rod 22 drives the grinding disc 13 at one end of the bottom to rotate. After the grinding disc 13 rotates, the raw materials on the end surface of the grinding disc 13 are thrown into the interior of the grinding groove 18 by centrifugal force, so that the raw materials enter the V-shaped groove 19, and the rotating grinding disc 13 and the grinding groove 18 rub and crush the raw materials to crush the raw materials into powder.

[0020] For further reference, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The outer circumferential surface of the upper end surface of the grinding disc 13 is processed into an arc. Through this setting, the raw material can slide around along the arc surface by gravity and enter the interior of the grinding groove 18 for grinding, thereby improving the grinding efficiency. A guide ring 14 is provided on the top of the grinding ring 15. The guide ring 14 is provided with an annular inclined surface. By setting the annular inclined surface, the poured raw material can enter the end surface of the grinding disc 13 along the inclined surface, preventing the raw material from staying on the end surface of the grinding ring 15 to cause grinding dead corners and uneven grinding, thereby improving the grinding effect.

A plurality of fixing frames 45 are provided on one end of the transmission shaft and the end surface of the fixed base 12, and a second motor is provided on the outer surface of the plurality of fixing frames 45. The output shafts of the plurality of second motors are respectively connected to the transmission shaft. When the raw material is subjected to secondary grinding, the first motor and the second motor are started first, and the first motor is driven by the transmission shaft. The movable rod 22 drives the grinding disc 13 to rotate. After the grinding disc 13 rotates, it drives the movable plate 23 at the bottom to rotate through the connecting rod 46, so that the movable plate 23 throws the raw materials on the end surface into the fine grinding groove 44 through centrifugal force. At the same time, after the rotation, the movable plate 23 drives the raw materials on the end surface to rotate. Under the joint action of the grinding roller 43 and the fine grinding groove 44, the raw materials are crushed into powder.

After the grinding disc 13 rotates, it will drive the bottom fan blade 21 to rotate together. The feed port 11 forms an upward airflow after rotation, which blows the powdered raw material, thereby separating the powdered raw material and the block raw material, so that the screen 24 can be screened to improve the feeding efficiency. A first coaxial gear transmission is provided between the grinding disc 13 and the fan blade 21. The first coaxial gear transmission is a transmission based on the principle of planetary gears, with input and output on the same straight line, realizing a gear transmission device with the input shaft and output shaft located on the same central axis.

A second coaxial gear transmission is provided at one end of the bottom of the fan blade 21. The fan blade 21 is connected to the top output shaft of the second coaxial gear transmission. The output shaft of the bottom end face is fixedly connected to the connecting rod 46. By setting a second coaxial gear transmission, the rotation speed of the lower connecting rod 46 and the movable plate 23 can be reduced, thereby facilitating the discharge of the screen plate 24 on the surface of the movable plate 23. The end face of the movable plate 23 is provided with a plurality of cleaning blocks 25 on the inner wall of the grinding chamber 10. The bottom end faces of the plurality of cleaning blocks 25 are all provided with downwardly protruding protrusions 27. The plurality of downwardly protruding protrusions 27 all abut against the inside of the fine grinding groove 44. When the movable plate 23 rotates, it will drive the fine grinding groove 44 and the protrusions 27 to rub and scrape each other. By setting the protrusions 27, the crushed raw materials can be prevented from agglomerating into cakes inside the fine grinding groove 44. During the rotation of the fine grinding groove 44, the protrusions 27 shovel up the crushed raw materials and guide the raw materials to the upper end face of the screen 24 through the side of the cleaning block 25, so that the powdered raw materials with qualified particle size are discharged through the screen 24.
