Description

Technical Field

[0001] The utility model relates to the technical field of food seasoning processing, in particular to a food raw material grinding device. Background Art

[0002] In the food production process, it is often necessary to use a grinding device to grind the raw materials into powder for subsequent processing. The grinding of raw materials is a crucial link that directly affects the taste, quality and production efficiency of the food.

[0003] The existing grinding device has a simple design structure and usually does not pre-process the raw materials (such as crushing them), but directly grinds them, resulting in poor grinding effect. The size, shape and hardness of the raw materials are different, resulting in uneven grinding effect. Some raw materials are not ground thoroughly, resulting in low food production efficiency. Some raw materials are not ground thoroughly and directly enter the grinding powder. The incompletely ground raw materials will reduce the quality of the food and are inconvenient to use.

[0008] Preferably, the outer surface of the crushing roller is provided with a plurality of protruding teeth, and the protruding teeth of the crushing roller are meshed with each other.

[0009] Through the above technical solution, the high-speed rotation and mutual engagement of the crushing rollers can quickly reduce the size of material particles. The feed plate ensures that the material after being crushed by the crushing rollers can enter the grinding cylinder evenly and stably. By adjusting the parameters such as the speed of the crushing rollers, the shape and number of the protruding teeth, flexible adaptation to different materials can be achieved.

[0010] Preferably, the grinding assembly includes a drive motor, a grinding plate, a hopper scraper and a scraper, and the grinding plate, the hopper scraper and the scraper are sequentially mounted on a rotating shaft, the rotating shaft is mounted on the output end of the drive motor, and a feed port is opened on the grinding plate.

The grinding assembly 3 is located in the grinding cylinder 1 between the crushing feed box 2 and the material receiving tray 7. The fixed grinding plate 4 and the drop hopper 5 are both fixedly installed on the inner wall of the grinding cylinder 1. The drop hopper 5 is in the shape of an inverted round table, which is convenient for collecting and dropping materials. The crushing feed box 2 is installed at the end of the grinding cylinder 1, which is used to preliminarily crush the material to be ground and feed it into the grinding cylinder 1. The fixed grinding plate 4 is installed on the inner wall of the grinding cylinder 1, and cooperates with the grinding component 3 to grind the material into powder. The material is preliminarily crushed by the crushing feed box 2, which reduces the workload of the subsequent grinding component 3 and the fixed grinding plate 4. The material is finely ground by the grinding component 3 and the fixed grinding plate 4, which improves the grinding efficiency. The fixed grinding plate 4 is mounted on the grinding cylinder 1 through a support formed by four support sheets, and the support sheets are welded to the grinding cylinder.

The sieve plate 6 cooperates with the material receiving tray 7 below it to separate qualified fine powder. The sieve plate 6 is designed to be pull-out type, which is convenient for cleaning and replacement, and easy to take out and clean the collected materials, and separate the incompletely ground raw materials from the qualified raw materials to increase the grinding output quality. The incompletely ground raw materials will be left on the sieve plate 6. The slot and the clamp cooperate to complete the fixation of the insertion end to prevent the sieve plate 6 from tilting.

[0028] The crushing feed box 2 includes a feed box 22, several crushing rollers 21 and a feed plate 23. The several crushing rollers 21 are connected to the inner wall of the feed box 22 through the rotation of the motor.

The two crushing rollers 21 move inward relative to each other under the drive of the motor to crush the raw materials. The feed plates 23 are relatively arranged in an inverted eight shape, and enter the grinding assembly 3 with the feed plate 23 for grinding.

[0029] The grinding assembly 3 includes a driving motor 31, a grinding plate 32, a hopper scraper 33 and a scraper 34. The grinding plate 32, the hopper scraper 33 and the scraper 34 are sequentially mounted on the rotating shaft, the rotating shaft is mounted on the output end of the driving motor 31, a feed port is opened on the grinding plate 32, the grinding plate 32 is overlapped on the fixed grinding plate 4, the grinding plate 32 and the fixed grinding plate 4 cooperate like a stone mill, the rotating shaft passes through the fixed grinding plate, the hopper scraper 33 is adapted to the drop hopper 5 to prevent the raw materials from sticking and being unable to drop, the scraper 34 is located above the screen plate 6, and the crushed raw materials are introduced into the grinding plate 32 by the feed plate 23. The driving motor 31 drives The dynamic grinding plate 32 rotates. At this time, the raw material is driven by centrifugal force to rotate and enter the feed port on the grinding plate 32. An observation window is provided on the grinding cylinder 1 for easy observation of the grinding situation. The scraper 34 is close to the screen plate 6 and a soft brush is installed on the bottom surface of the scraper 34 to prevent blockage and keep the screen unobstructed, thereby ensuring the accuracy and continuity of screening. It not only helps to control the flow of raw materials, but also plays a role in screening. The ground material is screened through the screen plate 6. Qualified materials pass through the screen, and unqualified materials are intercepted for easy subsequent processing. When the screen plate 6 is pulled out, the staff can perform multiple slight pulls for thorough screening.

[0030] Working principle: Start the crushing feed box 2, and the motor drives the crushing roller 21 to rotate relatively inward. At this time, the staff puts in food raw materials and crushes them. The feed plate 23 introduces them into the upper surface of the grinding plate 32, and further starts the drive motor 31 to drive it. The raw materials enter from the feed port of the grinding plate 32 and are ground with the fixed grinding plate 4. The ground materials are guided by the drop hopper 5 and enter the sieve plate 6 for screening and separation. The grinding situation is observed through the observation window. After the grinding is completed, the sieve plate 6 and the material receiving tray 7 are pulled out for subsequent processing.
