Description

Technical Field

[0001] This utility model relates to the field of grain puffing and processing technology, specifically a device for puffing and processing grains and grinding them into ultrafine powder. Background Technology

[0002] The term "five grains" refers to a variety of cereals and legumes, including various grain crops. In ancient times, there were several different interpretations of "five grains," but the two most common are: one referring to rice, millet, sorghum, wheat, and beans; and the other referring to hemp, millet, sorghum, wheat, and beans, though the former is usually used. "Miscellaneous grains," on the other hand, refers to cereals and legumes other than staple grain crops such as rice and wheat.

[0003] Whole grains are an important source of carbohydrates, with legumes being particularly rich in high-quality protein and dietary fiber, which can promote intestinal peristalsis, prevent constipation, and reduce the risk of colon cancer. They can also slow down the absorption of carbohydrates, helping to control the rate of blood sugar rise. They contain abundant B vitamins, such as vitamins B1, B2, and B6, as well as minerals such as vitamin E, potassium, magnesium, iron, and zinc.

[0004] When processing grains into powder, it is necessary to grind the grains into powder and then puff the powder. However, common grain puffing and grinding ultrafine powder equipment requires screening the grain powder during the grinding process. The screened grain powder needs to be removed and put back into the grinding equipment for secondary grinding. In view of this, this application proposes a grain puffing and grinding ultrafine powder equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for puffing and grinding grains into ultrafine powder. It has the advantages of facilitating secondary grinding of unscreened grain powder, thus solving the problem that common grain puffing and grinding devices require screening of grain powder during grinding, and then removing the screened grain powder and putting it back into the grinding device for secondary grinding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for puffing and grinding grains into ultrafine powder, comprising a mounting base, two support plates fixedly mounted on the top of the mounting base, rotating shafts rotatably mounted on opposite sides of the two support plates, a grinding cylinder fixedly mounted between the two rotating shafts, a mounting beam fixedly mounted on the inner wall of the grinding cylinder, a grinding cylinder fixedly mounted on the bottom of the mounting beam, a grinding head fixedly mounted on the movable end of the grinding cylinder, a screening screen fixedly mounted on one side of the grinding cylinder, the screening screen being perpendicular to the grinding head, and a feed inlet opening at the top of the grinding cylinder.

[0007] Furthermore, the top of the mounting beam is configured as an arc-shaped structure, and the bottom of the grinding head is an arc-shaped structure adapted to the inner wall of the grinding cylinder.

[0008] Furthermore, mounting rods are fixedly installed on opposite sides of the two supporting uprights, and a feed hopper is fixedly installed between the two mounting rods.

[0009] Furthermore, a rotating motor is fixedly installed on one side of the supporting plate, and the output shaft of the rotating motor is fixedly connected to one end of the rotating shaft.

[0010] Furthermore, a mounting plate is fixedly installed on the top of the mounting base, an extrusion puffing machine is fixedly installed on one side of the mounting plate, and a receiving hopper is fixedly installed on the top of the extrusion puffing machine.

[0011] Furthermore, an extrusion motor is fixedly installed on one side of the mounting plate, and a heater is fixedly installed on the surface of the extrusion puffing machine.

[0012] Furthermore, a base mold is fixedly installed at the output end of the extrusion puffing machine, and a reinforcing support plate is fixedly installed on the top of the mounting base. The top of the reinforcing support plate is fixedly connected to the bottom of the extrusion puffing machine.

[0013] Compared with the prior art, this utility model provides a device for puffing and grinding grains into ultrafine powder, which has the following beneficial effects:

[0014] This device for puffing and grinding grains into ultrafine powder involves rotating a grinding cylinder between two supporting plates. After the grains are ground on the inner bottom wall of the grinding cylinder, the cylinder rotates 90 degrees, moving the screen to the bottom to screen the grain powder. After screening, the grinding cylinder returns to its original position, leaving unscreened grain powder on the inner bottom wall for secondary grinding. This solves the problem of common grain puffing and grinding devices requiring screening of grain powder before grinding, and the need to remove the screened powder and place it back into the grinding device for secondary grinding.
