A sand ball flexible rice mill and a grain medium rice milling method

Abstract

The invention discloses a sand ball flexible rice milling machine and a grain medium rice milling method. The technical points of the rice milling machine are: a frame 8 is a machine casing composed of a barrel base 21, an outer barrel 3, and a machine cover 2 , on the inner side above the machine barrel seat 22 and the inner side of the machine outer cylinder 3, there is a hollow shaft 5 installed through the bearing assembly 20, the upper end sealing assembly 22, the lower end sealing assembly 17 and the bearing cover 19; the hollow shaft The top device of 5 gets rid of the material tray 23; the outer surface of the hollow shaft is symmetrically and evenly distributed with a plurality of blades 6. The grain medium rice milling method is to batch the grain and sand ball quality, transport the mixture, softly mill rice with sand balls, lift the mixture, and then softly mill rice with sand balls, grade the mixture of grain and sand balls, sort out the finished product, and recycle and recycle the sand balls Use equal sections. The invention has the advantages of simple structure of the rice mill, large milling contact area, low pressure in the rice milling chamber, low rotational speed, low broken rice rate and high rice output rate.

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
