Description

Technical Field

[0001] The utility model relates to a multi-stage superfine pulverizer for food processing, belonging to the technical field of food processing equipment. Background Art

[0002] At present, in the process of food processing and production, raw materials need to be crushed for subsequent processing. At present, most food grinders use motors to drive blades to rotate in a cylinder or groove to crush food raw materials. Only food with a qualified particle size can pass through the sieve plate and be discharged. Usually there is only one crushing device. When crushing, food is put in at one time for crushing, which is easy to cause accumulation and damage the machine. In addition, the sieve plate of the food grinder is generally fixed. During the crushing process, the food will sink to the bottom. The sinking food not only blocks the sieve plate but also is not within the working range of the crushing device, which seriously reduces the crushing efficiency.

[0003] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a multi-stage ultrafine pulverizer for food processing to make it more valuable for industrial use. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a multi-stage ultra-fine pulverizer for food processing.

[0005] The utility model discloses a multi-stage ultrafine pulverizer for food processing, comprising a base, a pulverizing cylinder is arranged on the top of the base, a filter disc slot is arranged on the bottom of the pulverizing cylinder, a replaceable multi-stage filter disc is inserted and pulled out in the filter disc slot, a pulverizing feed port is arranged on one side of the top of the pulverizing cylinder, a pulverizing motor is arranged at the center position of the top of the pulverizing cylinder, a pulverizing shaft is arranged at the output end at the bottom of the pulverizing motor in the vertical direction, a bottom scraper is arranged at the bottom of the pulverizing shaft in the horizontal direction, and a plurality of pulverizing blades are sleeved at equal distances on the surface of the pulverizing shaft.

[0006] Furthermore, the crushing blade has a plurality of blade leaves, each blade leaf surface is provided with a large crushing hole and two small crushing holes located on both sides of the large crushing hole, and crushing blades are also provided on both sides of each blade leaf. The food raw materials are crushed by the shear force when the crushing blades rotate, and each layer of the crushing blades is staggered so that the multi-layer crushing blades just cover the entire cross-section of the crushing barrel. The large crushing holes and small crushing holes on the surface of each layer of crushing blades are used to filter and screen the food raw materials falling from the top, slowing down the falling speed of the raw materials, so that they are fully graded and crushed by the crushing blades, thereby improving the crushing efficiency;

[0007] Furthermore, a material receiving bin is provided in the base, a material receiving barrel is inserted in the material receiving bin, and a material receiving barrel handle is provided on the outside of the material receiving barrel, so that the user can conveniently pull out and insert the material by hand.

[0008] Furthermore, there are multiple replaceable multi-stage filter discs, and the surface of each replaceable multi-stage filter disc is evenly provided with multiple filter holes, and the apertures of the filter holes on the surface of each replaceable multi-stage filter disc are different. When in use, according to different graded crushing requirements, a large-aperture replaceable multi-stage filter disc is first used for primary crushing, and then a small-aperture replaceable multi-stage filter disc is used for subsequent graded fine crushing until the crushing requirements are met, and finally the finished product is collected;

[0009] Furthermore, a filter tray handle is provided on the outside of the replaceable multi-stage filter tray, which is convenient for users to pull out and insert by hand, and convenient for replacing the replaceable multi-stage filter trays of different levels.

[0010] Furthermore, the grinding cylinder is a cylindrical structure.

[0011] Furthermore, a filter plate placement platform is provided on the inner wall of the top of the base, which is used to stably support the inserted replaceable multi-stage filter plate.

[0012] Furthermore, the grinding feed port is connected to the inside of the grinding cylinder, and is used to add food materials to be ground;

[0013] Furthermore, the bottom surface of the bottom scraper is in contact with the surface of the replaceable multi-stage filter disc, and is used to rotate and scrape the crushed materials on the surface of the replaceable multi-stage filter disc to prevent the crushed materials from clogging the filter holes on the surface of the replaceable multi-stage filter disc;

[0014] Furthermore, the length of the pulverizing shaft is smaller than the depth of the pulverizing cylinder; the length of the bottom scraper bar is smaller than the inner diameter of the pulverizing cylinder.

[0015] By means of the above scheme, the present invention has at least the following advantages:

[0016] When the utility model is used, according to different graded crushing requirements, a large-aperture replaceable multi-stage filter disc is first used for primary crushing, and then a small-aperture replaceable multi-stage filter disc is used for subsequent graded fine crushing until the crushing requirements are met, and the crushing efficiency is high;

[0017] The bottom surface of the bottom scraper bar contacts the surface of the replaceable multi-stage filter disc, and is used to rotate and scrape the crushed materials on the surface of the replaceable multi-stage filter disc to prevent the crushed materials from clogging the filter holes on the surface of the replaceable multi-stage filter disc;

[0018] The large and small crushing holes on the surface of each layer of crushing blades can filter and screen the food raw materials falling from the top, slowing down the falling speed of the raw materials so that they can be fully graded and crushed by the crushing blades, thereby improving the crushing efficiency.
