Multi-channel stone removing device for rice processing and implementation method thereof

Abstract

The invention discloses a multi-channel stone removing device for rice processing and an implementation method thereof. The multi-channel stone removing device comprises a grinding and feeding mechanism, a stone removing shell, an outer clamping and embedding arm, a movable motor and a guide sleeve, wherein rice passes through the grinding and feeding mechanism, is simply ground between grinding rollers and then enters the stone removing shell through a feeding pipe and a feeding port, stone removing screening mechanisms are provided with stone removing screen sleeves and stone removing screenplates, the stone removing screen sleeves and the stone removing screen plates in the stone removing screening mechanisms conduct swing screening, after screening is completed, the rice falls into anoblique screening mechanism downwards, multi-layer multi-angle screening is conducted through the oblique screen plate, and after screening is completed, the rice falls into the guide sleeve throughan oblique groove and is shunted and discharged. According to the multi-channel stone removing device, a plurality of different screening mechanisms are arranged, the rice is effectively stone-removedand screened for multiple times, the content of impurities in the rice is reduced, the time consumed by stone-removing operation again is effectively shortened, the stone-removing quality is high, and the stone-removing operation is rapid and convenient.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a multi-channel stone removing device for rice processing and an implementation method thereof. Background technique [0002] Rice refers to the fruit without removing the rice husk, which belongs to the common rice subspecies in the common cultivated Oryza subgenus of Poaceae Oryza botany in botany. Rice processing refers to the process of removing the rice husk and cortex. The purpose is to The endosperm is separated from other parts with the minimum degree of crushing to make rice with better edible quality. The process of rice processing is mainly divided into three main processes: cleaning, husking and rice milling. The rice is mixed with sand, gravel and soil. , coal dust, iron nails, rice stalks and weed seeds and other impurities, which cannot be removed during processing, will not only affect safe production, reduce the quality of rice, but also be harmful to hum...

[0002] Rice refers to the fruit without removing the rice husk, which belongs to the common rice subspecies in the common cultivated Oryza subgenus of Poaceae Oryza botany in botany. Rice processing refers to the process of removing the rice husk and cortex. The purpose is to The endosperm is separated from other parts with the minimum degree of crushing to make rice with better edible quality. The process of rice processing is mainly divided into three main processes: cleaning, husking and rice milling. The rice is mixed with sand, gravel and soil. , coal dust, iron nails, rice stalks and weed seeds and other impurities, which cannot be removed during processing, will not only affect safe production, reduce the quality of rice, but also be harmful to human health. The cleaning process mainly focuses on the removal of impurities in rice, Husking is the process of peeling off the hull of rice to make it into brown rice. After hulling and separating rice paddy into brown rice, the cortex on the surface contains more fiber, which affects the eating quality. The rice milling process is to grind the cortex of brown rice. Removal, thus becoming the process of rice, in which the stone removal process is an extremely important step in the cleaning process. At present, the specific gravity stone removal machine is usually used in the stone removal process to remove the stones in the rice, and this equipment can only perform one-way cleaning. A one-time stone removal operation, which cannot guarantee that the internal impurities are cleaned, and repeated stone removal operations will take a long time
