Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and more specifically, to a rice processing device. Background Technology
[0002] Rice is the edible part of paddy rice after it has been hulled, milled and other processed. Its scientific name is Oryzasativa (Asian rice) or Oryzaglaberrima (African rice). It is the staple food of more than half of the world's population and has an irreplaceable position in China, India and Southeast Asia.
[0003] Rice processing equipment refers to the process of removing the husk, bran, and germ (partially retaining) of paddy through a series of physical and mechanical treatments to obtain white rice or fortified rice that meets food safety standards. Its core objectives are to increase rice yield, ensure food safety, and improve rice quality and added value.
[0004] Rice processing requires the removal of rice husks. This is usually achieved by continuously blowing strong air from a fan onto the rice, causing the husks to detach from the rice. The detached husks are then blown into the husk discharge chamber, thus sieving the rice. However, the rice tends to clump together as it falls, making it difficult for the fan's airflow to separate them effectively. This reduces the sieving efficiency of the husk removal device. Furthermore, the rice needs to be manually guided into the husk removal device during the husk removal process, which is quite cumbersome. Utility Model Content
[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a rice processing equipment to solve the technical problem mentioned in the background art that rice tends to clump together when falling, and the air force generated by the fan is not enough to fully separate it, thereby reducing the screening efficiency of the rice sieving device.
