Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically, it relates to a grinding device for processing food additives. Background Technology

[0002] Food additives are substances added to food during production, processing, and storage to improve its quality and structure, and to prevent oxidation, spoilage, and deterioration due to technological requirements. They are usually a mixture of multiple raw materials, and the raw materials often need to be ground before processing.

[0003] The fineness of grinding is closely related to the quality of the finished product. Currently, vertical grinding equipment is commonly used in the market. The grinding mechanism is set at the bottom of the cylinder. The material that has been ground to the appropriate size is discharged through the screen at the bottom. However, during the grinding process, there are materials of various sizes, which can easily clog the screen and reduce the discharge efficiency. Utility Model Content

The plurality of grinding moving rings are rings of different diameters and are all disposed coaxially with the cylinder. The stator extends between the grinding moving rings and is close to the rear cover. The stator is composed of a plurality of ring structures of different diameters, and the ring structures of the stator and the plurality of grinding moving rings are arranged alternately.

[0008] The present invention is further configured such that: a plurality of sieve holes are provided on both the grinding moving ring and the stator, the sieve holes are evenly arranged circumferentially, the diameter of the sieve holes on the grinding moving ring with a larger diameter is smaller than the diameter of the sieve holes on the grinding moving ring with a smaller diameter, the diameter of the sieve holes on the annular structures of different diameters of the stator corresponds to the diameter of the sieve holes on the different grinding moving rings, and the diameter of the sieve holes on the inner side of the stator is larger than the diameter of the sieve holes on the outer side of the stator.

[0009] The present invention is further configured such that: a rotating shaft is provided at the center of the rear cover, the rotating shaft extends into the feed pipe, and a feed impeller is installed on the rotating shaft.

[0022] Please see Figure 1-4 The present invention provides the following technical solution:

[0023] A grinding device for processing food additives includes a base frame 1, a cylindrical body 2 fixed on the base frame 1, the cylindrical body 2 being arranged horizontally, an opening at one end of the cylindrical body 2, a bottom at the end of the cylindrical body 2 away from the opening, a motor 3 mounted on the bottom of the cylindrical body, a rotor 4 connected to the output shaft of the motor 3, the rotor 4 being disposed inside the cylindrical body 2, a cover 5 covering the opening, a feed pipe 51 connected to the side of the cover 5 away from the cylindrical body 2, a stator 6 arranged on the side of the cover 5 facing the cylindrical body 2, the stator 6 and the rotor 4 being arranged alternately, both the stator 6 and the rotor 4 having a plurality of sieve holes 7, and a discharge port 21 connected to the side of the cylindrical body 2 facing the base frame 1.

[0024] The equipment is horizontal in structure. The raw material enters between the stator 6 and the rotor 4 through the feed pipe 51. When the motor 3 controls the rotor 4 to rotate, the raw material is ground. The ground material passes through the screen hole 7 and is finally discharged through the discharge port 21.

[0025] The rotor 4 includes a rear cover 41, which is set close to the bottom of the cylinder. A plurality of grinding rings 43 are connected to the side of the rear cover 41 away from the motor 3. The plurality of grinding rings 43 are rings of different diameters and are all set coaxially with the cylinder 2. The stator 6 extends between the grinding rings 43 and is close to the rear cover 41. The stator 6 is composed of a plurality of ring structures of different diameters. The ring structures of the stator 6 and the plurality of grinding rings 43 are interleaved. When the rotor 4 rotates, the grinding rings 43 and the stator 6 rotate relative to each other, thereby crushing the material between them.

[0026] Both the grinding moving ring 43 and the stator 6 are provided with a number of sieve holes 7. The sieve holes 7 are evenly arranged in the circumference. The diameter of the sieve holes 7 on the inner grinding moving ring 43 is larger than that on the outer grinding moving ring 43. The diameter of the sieve holes 7 on the annular structures of different diameters of the stator 6 corresponds to the diameter of the sieve holes 7 on the different grinding moving rings 43. That is, the diameter of the sieve holes 7 on the inner side of the stator 6 is larger than that on the outer side of the stator 6.

[0027] The ground material can pass through the sieve hole 7. The sieve hole 7 on the grinding ring 43 and the stator 6 decreases in diameter from the inner layer to the outer layer, which can achieve graded grinding, making the material gradually finer, making it easier for the material to pass through the sieve hole 7, reducing clogging and improving the discharge efficiency.

[0028] A rotating shaft 42 is provided at the center of the rear cover 41. The rotating shaft 42 extends into the feed pipe 51. A feed impeller 46 is installed on the rotating shaft 42. The feed impeller 46 can push the material in the feed pipe 51 into the cylinder 2 to ensure the feeding speed and prevent the material from accumulating in the feed pipe 51.

[0029] A number of guide plates 44 are evenly arranged along the circumference of the back cover 41. The guide plates 44 are located between the rotating shaft 42 and the grinding ring 43. The guide plates 44 are arc-shaped and are arranged in an inclined direction. When the rotor 4 rotates, the back cover 41 drives the guide plates 44 to rotate synchronously, thereby pushing the material at the center outward, increasing the contact area between the material and the rotor 4 and the stator 6, and improving the grinding efficiency.

[0030] Several scraper blades 45 are evenly arranged on the outer wall of the outermost grinding ring 43. The outer side of the scraper blades 45 is in contact with the inner wall of the cylinder 2. The ground powder is finally between the inner wall of the cylinder 2 and the outermost grinding ring 43. When the rotor 4 rotates, the scraper blades 45 scrape the inner wall of the cylinder 2, which prevents the material from accumulating in the cylinder 2 and pushes the material out from the discharge port 21, thus improving the discharge efficiency.

[0031] Specifically, the equipment is configured as a horizontal structure. Several grinding rings 43 of the rotor 4 and the annular structure of the stator 6 are arranged in an alternating manner to form a grinding structure. Several screen holes 7 are opened on both the grinding rings 43 and the stator 6. The inner screen holes 7 have a large aperture and the outer screen holes 7 have a small aperture. When the raw material enters from the feed pipe 51, it is pushed towards the grinding structure by the feed impeller 46 and the guide plate 44. The raw material is filtered by the screen holes 7 of different apertures to achieve graded grinding, which reduces the risk of screen hole 7 clogging and ensures the discharge efficiency.
