Multi-stage grinding type rice flour milling process

Abstract

The invention provides a multi-stage grinding type rice flour milling process. The multi-stage grinding type rice flour milling process comprises the following steps that firstly, a user adds rice toan outer cylinder I through a funnel; then, a driving member drives a rotating shaft I to rotate, a grinding cylinder I rotates and drives the outer cylinder I to rotate, and the rice located at the combined part of the grinding cylinder I and the outer cylinder I is subjected to grind and coarse grinding processing; a conveying channel conveys the coarse ground rice flour into an outer cylinder II from the outer cylinder I, a rotating shaft I drives a rotating shaft II to rotate, the grinding cylinder II rotates to drive the outer cylinder II to rotate, and the rice flour located at the combined part of the grinding cylinder II and the outer cylinder II is subjected to grind and fine grinding processing; the fine ground rice flour is conveyed into an outer cylinder III from the outer cylinder II through a transmission channel, the rotating shaft II drives a rotating shaft III to rotate, a grinding cylinder III rotates and drives the outer cylinder III to rotate, and the rice flour located at the combined part of the grinding cylinder III and the outer cylinder III is subjected to grind and fine grinding; and finally, the fine ground rice flour is discharged out of the outer cylinder III through a discharging part, and the rice flour enters a discharging channel through a hopper, and guided and output into a collecting vessel through the discharging channel.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a multi-stage rolling rice milling process. Background technique [0002] Rice is one of the main grains of Chinese residents. It contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and rich in B vitamins. The carbohydrates in rice are mainly It is starch, and the protein contained is mainly rice glutenin, followed by rice glue protein and globulin. The biological value and amino acid composition ratio of the protein are higher than those of wheat, barley, millet, corn and other cereal crops, and the digestibility is 66.8%. -83.1%, making rice into rice flour is especially common, suitable for all physically weak people, people with high fever, long-term illnesses, women postpartum, the elderly, especially those with weakened digestion of infants and young children. At present, there are rice mills The flour mill grinds and pulverizes the rice placed between ...

[0002] Rice is one of the main grains of Chinese residents. It contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and rich in B vitamins. The carbohydrates in rice are mainly It is starch, and the protein contained is mainly rice glutenin, followed by rice glue protein and globulin. The biological value and amino acid composition ratio of the protein are higher than those of wheat, barley, millet, corn and other cereal crops, and the digestibility is 66.8%. -83.1%, making rice into rice flour is especially common, suitable for all physically weak people, people with high fever, long-term illnesses, women postpartum, the elderly, especially those with weakened digestion of infants and young children. At present, there are rice mills The flour mill grinds and pulverizes the rice placed between the upper and lower millstones that rotate with each other. The milling efficiency is low, and the feeding and discharging are inconvenient. Therefore, it is necessary to provide a milling machine with ingenious structure, simple principle, It is convenient to operate and use, convenient for feeding and discharging, and a multi-stage rolling rice milling processing method that can improve milling efficiency
