Technical Field

[0001] The utility model belongs to the technical field of rice milling, and particularly relates to a rice milling device. Background Art

[0002] Rice is a staple food for most of China. Rice, also known as paddy rice, is produced by milling rice husks, which separate the rice grains from the husks. After a series of refinements, the rice is processed into food. Harvested rice often contains foreign matter such as stones and dust, which can affect the quality of the resulting rice.

[0003] Patent application number 202223168778.2 discloses a rice milling device, including a device housing, a feed hopper is provided on the device housing, a dehumidification pipe and two rice milling rollers are provided inside the device housing; a first guide plate is provided between the dehumidification pipe and the feed hopper; the two rice milling rollers are provided below the dehumidification pipe, and a first screening plate is provided between the two rice milling rollers and the dehumidification pipe; a rice collecting box is provided at the bottom end of the device housing, and a second screening plate is provided between the rice collecting box and the two rice milling rollers; a vibration component is also provided in the device housing, and the vibration component is connected to the first screening plate and the second screening plate respectively.

[0004] The above technical solution utilizes two rice milling rollers rotating in opposite directions. The two rice milling rollers only squeeze the rice once, which makes it difficult for the rice to fall off from the rice husk, resulting in poor rice milling effect. At the same time, although the filter plate is set to filter the rice husk, since the rice is transported at the top of the inclined filter plate, the rice at the top is difficult to pass through the filter plate, resulting in poor rice processing effect.
