Description

Technical Field

[0001] The utility model relates to the field of rice processing, in particular to rice hulling equipment. Background Art

[0002] Rice hulling is the process of removing the outer shell of rice to turn it into brown rice. For example, the Chinese patent with patent number CN202021491734.1 provides a rice hulling device; when working, the rice hulling device is driven by a driving mechanism to rotate the second grinding disc, and the feed pipe rotates synchronously with the second grinding disc. The grain enters the feed pipe through the feed hopper. As the second grinding disc rotates, the rice in the feed pipe enters the grinding disc through the feed port under the action of centrifugal force. The grinding protrusion grinds the grain on the second grinding disc, so that the husk of the grain is separated from the core of the grain. At the same time, under the action of centrifugal force, the grain moves to the edge of the second grinding disc and falls into the bottom cylinder; such as the hulling device in the above-mentioned prior art, when the rice is thrown out from the feed port by centrifugal force, the rice is easily blocked at the feed port, resulting in poor feeding. At the same time, it is difficult for the device to adjust the distance between the two grinding discs according to the size of the rice, resulting in incomplete rice hulling. Utility Model Content
