Flexible rice mill with abrasive balls and grain milling method

Abstract

The invention discloses a flexible rice mill with abrasive balls and a grain milling method. The flexible rice mill is technically characterized in that a frame unit 8 comprises a housing composed of a cylinder base 21, an outer cylinder 3 and a cover 2; a carborundum inner cylinder 4 is disposed inside the outer cylinder 3 inside the upper portion of the cylinder base 22; a hollow shaft 5 mounted through a bearing set 20, a top sealing set 22, a bottom sealing set 17 and a bearing cap 19 is disposed inside the housing; a thrower disc 23 is disposed at the top end of the hollow shaft 5; a plurality of paddles are symmetrically and evenly distributed on the outer surface of the hollow shaft. The grain milling method includes proportional compounding of grain and the abrasive balls, feeding of mixture, flexible milling by the abrasive balls, lifting of the mixture, secondary milling by the abrasive balls, grading of grain and abrasive ball mixture, finishing of finished products, recycling of the abrasive balls and the like. The flexible rice mill and the grain milling method have the advantages that the flexible rice mill is simple in structure, milling contact area is great, interior milling pressure is low, speed is low, rate of broken rice is low, and rice yield is high.

Description

technical field [0001] The invention belongs to the field of grain processing technical equipment, in particular to technical equipment for grain medium rice milling, in particular to a sand ball flexible rice mill and a grain medium rice milling method. Background technique [0002] As the existing grain rice milling technology, there are mainly cutting rice milling process, extrusion rice milling process and cutting and extrusion combined rice milling process. In grain (including rice, wheat, corn, miscellaneous grains, etc.) Rice machines; according to the arrangement of the rollers, there are mainly horizontal rice mills and vertical rice mills; according to the number of rollers in the rice mills, there are mainly single-roller rice mills, double-roller rice millers and multi-roller rice millers. crushing mill. According to the distribution of milling bars and milling grooves on the surface of the roller, it is mainly divided into continuous bars and segmental bars, s...

AI Technical Summary

Problems solved by technology

The second is that the pressure in the rice milling chamber is relatively high

However, if the pressure in the rice milling chamber increases, the broken rice rate will increase and the rice output rate will decrease.

In addition, as the pressure in the rice milling chamber increases, the energy consumption of the rice mill will increase

The third is that the roller speed is faster

[0014] This patented technology improves the interaction between wind and grains in the rice milling process and the structure of the rice milling chamber, but does not provide new insights into increasing the milling area, reducing the speed of the rollers, and reducing the pressure of the rice milling chamber
