Description

Technical Field

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

[0002] The rice rolling screening device is a device that screens rice by rolling. Rice, also known as paddy rice, is a food made from rice grains after cleaning, husking, milling, and finished product sorting. After the rice grains are made into rice, the rice rolling screening device needs to screen the rice to separate the broken rice and small stones in the rice, thereby improving the quality of the rice.

[0003] Patent No. CN202221032787.6 discloses a rice rolling screening device for rice processing, including a screening box, a collecting box fixedly installed at the bottom of the screening box, a supporting leg fixedly installed at the bottom of the collecting box, a bottom plate fixedly installed on the inner side of the supporting leg, a rolling screening mechanism provided on the top of the bottom plate, and a rolling screening mechanism including a first motor fixedly installed at the top of the bottom plate, a rotating shaft fixedly installed at the top of the first motor, a roller fixedly installed at one end of the rotating shaft away from the first motor, a scraper fixedly installed on the outside of the rotating shaft, a mounting sleeve fixedly installed on the top of the roller, and a rotating sleeve fixedly installed on the top inner wall of the screening box. The rice rolling screening device for rice processing drives the scraper to rotate synchronously through the rotating shaft, so that the scraper automatically scrapes the separated broken rice and stones into the collecting box, thereby achieving the effect of facilitating the centralized processing of the broken rice and stones.

[0004] The above-mentioned rolling screening device for rice processing drives the scraper to rotate synchronously through the rotating shaft, so that the scraper automatically scrapes the separated broken rice and stones into the collection box, thereby achieving the effect of facilitating the centralized processing of broken rice and stones. This method requires the scraper to be connected to the bottom of the drum. Although it ensures the centralized processing effect of broken rice and stones, it is not convenient to discharge the rice in the drum after screening, which increases the difficulty of taking the rice after screening, thereby affecting the screening efficiency. To this end, we propose a rolling screening device for rice fine processing. Utility Model Content
