Problems solved by technology

During the husking process, due to the greater extrusion force and impact force, the broken kernels of tartary buckwheat must be higher.
[0005] In addition, in the prior art, the dust generated by grinding and shelling will reduce the efficiency of grinding and shelling, and it needs to be removed in time.

Embodiment approach 1

[0059] Embodiment 1: A low-pressure grinding type shelling device

[0060] Such as figure 1 and figure 2 As shown, the described aspiration-type tartary buckwheat low-pressure grinding and hulling machine includes a casing 10, the casing 10 is an upright cylindrical shape, and the inside of the casing 10 is concentrically equipped with a grinding cylinder 7 and Knead the cylinder 12; the grinding cylinder 7 is on the top, and the kneading cylinder 12 is on the bottom.

[0061] Such as figure 1 , Figure 9 and Figure 10 As shown, on the inner wall of the casing 10 corresponding to the upper end position of the grinding cylinder 7, an upper annular retaining ring 4 is fixed by bolts, and the gap position between the lower end of the grinding cylinder 7 and the upper end of the kneading cylinder 12 is fixed by bolts. The inner wall of the casing 10 is fixedly equipped with a middle annular retaining ring 11, and the inner wall of the casing 10 at the lower end position of ...

Embodiment approach 2

[0081] Embodiment 2: A method of using a low-pressure grinding shelling device

[0082] The tartary buckwheat grains with appropriate moisture content are poured from the feed hopper 1, and the feed flow is controlled by the feed valve 2, and the grains fall to the conical sliding cover 28 by the feed valve 2 and slide into the grinding chamber 6, because The high-speed operation of the grinding roller 26 and the helical arrangement of the grinding discs 53 in the vertical direction make the grains form a certain accumulation in the grinding chamber 6 and fall as a whole under the action of gravity; during the falling process of the grains, the grinding The corundum abrasive on the surface of the cylinder 7 and the grinding roller 26 grinds the husks of the grains so that the husks at the corners are worn off, and the kernels at the corners gradually leak out, and the bonding strength of the husks is greatly reduced. During the grinding process, the right-hand spiral of the gr...

Abstract

The invention discloses an air-breathing type tartary buckwheat low-pressure grinding huller, and belongs to the field of grain hulling machines. The huller comprises a machine shell, a grinding cylinder is vertically fixed at the center of the machine shell, a grinding air bag is mounted between the grinding cylinder and the side wall of the machine shell, and grinding rollers are concentrically mounted in the grinding cylinder; a feed hopper is mounted at the top of the grinding cylinder, and a feed control door is arranged at the bottom of the feed hopper; a kneading cylinder is arranged just below the grinding cylinder, a kneading air bag is mounted between the kneading cylinder and the machine shell, and kneading rollers are concentrically mounted in the kneading cylinder; a material flowing groove is formed below the kneading cylinder, and a hulled material outlet and a cleaning device connector are arranged obliquely below the material flowing groove. An air suction pipe is mounted at the top of the machine shell and is connected with a fan. In the whole hulling process, due to the buffering effect of the grinding air bag and the kneading air bag, the working pressure of tartary buckwheat is very low and is dynamically regulated; and meanwhile, an air suction component can immediately clean dusts, cool down and dehumidify, prolong the grinding process, and effectively improve the complete kernel yield of the tartary buckwheat during hulling.

Description

technical field [0001] The invention relates to an air-breathing low-pressure grinding and shelling machine for tartary buckwheat, which belongs to the field of small miscellaneous grain shelling machinery. Background technique [0002] Tartary buckwheat is known as "the king of five grains". It not only has excellent nutritional and health value, but also contains special trace elements and medicinal ingredients that other food crops do not have. It is an internationally recognized crop with both medicine and food. my country is the country that grows tartary buckwheat in a large area in the world, with a cultivation area of ​​about 300,000 hm 2 , with an output of 300,000 to 500,000 tons, both of which rank first in the world. However, the amount of deep processing of tartary buckwheat in my country is relatively small, accounting for only about 5% of the total output. [0003] The shape of tartary buckwheat grains is a triangular pyramid structure, the conical surface i...
