Embodiment approach 1

[0054] Embodiment 1: A dynamic pressure-regulating grinding type tartary buckwheat hulling machine

[0055] Such as figure 1 and figure 2 As shown, the described a kind of dynamic pressure regulating grinding type tartary buckwheat 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 a kneading circle. Cylinder 12; the grinding cylinder 7 is on the top, and the kneading cylinder 12 is on the bottom.

[0056] 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...

Embodiment approach 2

[0076] Embodiment 2: A method of using a dynamic pressure-adjusting grinding type tartary buckwheat hulling machine

[0077] 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 pro...

Abstract

The invention discloses a grinding type tartary buckwheat huller with dynamic pressure regulation, which belongs to the field of grain hulling machines. The huller comprises a shell, wherein a grinding cylinder is vertically fixed in the middle of the shell; grinding air bags are arranged between the grinding cylinder and the side wall of the shell; a grinding roller is concentrically arranged in the grinding cylinder; a feed hopper is arranged on the top part of the grinding cylinder; a feed control gate is arranged on the bottom part of the feed hopper; a kneading cylinder is arranged right under the grinding cylinder; kneading air bags are arranged between the kneading cylinder and the shell; a kneading roller is concentrically arranged in the kneading cylinder; a draining slot is arranged under the kneading cylinder; a hulling discharge hole and a cleaning device connector are arranged under the draining slot. During the whole hulling process, with the buffer functions of the grinding air bags and the kneading air bags, the working pressure on tartary buckwheat is less and can be dynamically regulated, and the rate of perfect kernels of tartary buckwheat hulling is effectively improved.

Description

technical field [0001] The invention discloses a dynamic pressure-regulating grinding type tartary buckwheat hulling machine, which belongs to the technical field of grain hulling 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 is deeply concave...
