Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rapid crushing device for rice processing. Background Art

[0002] Rice is a finished product made from rice grains after cleaning, husking, milling, and finishing. It contains approximately 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is rich in B vitamins. The primary carbohydrate in rice is starch, while the primary protein is glutenin, followed by gelatin and globulin. The biological value and amino acid composition of rice protein are higher than those of cereals such as wheat, barley, millet, and corn. With a digestibility of 66.8%-83.1%, it is also one of the highest among cereal proteins. Therefore, rice has a high nutritional value. Rice processing often requires pulverization.

[0003] A search of a Chinese patent publication with publication number CN221230694U has revealed a rapid pulverizing device for rice processing. The key technical features of the device are as follows: the device comprises a main body, the main body comprising an outer shell, and a hydraulic support fixedly mounted on the inner bottom end of the outer shell; a motor drives a reducer to rotate, the reducer drives a connecting shaft to rotate, the connecting shaft drives a rotating rod to rotate, and the rotating rod drives a second pulverizing disk to rotate. The rotation of the second pulverizing disk enables the rice flowing between the first and second pulverizing disks to be pulverized.

Therefore, we propose a fast grinding device for rice processing to solve the above problems. Utility Model Content
