Description

Technical Field

[0001] The utility model belongs to the technical field of rice processing, and more specifically, particularly relates to a rice hulling device for processing. Background Art

[0002] Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling, and finished product sorting. The cleaning process is to use suitable equipment, appropriate process flow and proper operation methods to remove various impurities mixed in the rice to improve the quality of the finished rice product. At the same time, magnets are used to remove iron nails, iron filings, etc. in the rice. The current rice processing hulling device does not perform screening before hulling, which can easily cause the hulling roller to be stuck by larger sand and gravel, thus affecting the normal use of the entire device.

[0003] Patent application number CN202223007724.8 discloses a rice hulling device, which solves the problem that the current rice hulling device does not perform screening before hulling, which easily causes the hulling roller to be stuck by larger sand and gravel, thereby affecting the normal use of the entire device. The device comprises a box body, the upper end of the inner wall of the box body is rotatably connected to two rotating shafts, and a hulling roller is fixed on the outer side of the rotating shaft; the double-axis motor of the utility model drives the rotating shaft to rotate through a first belt, and at the same time, one rotating shaft drives the roller to rotate through a second belt, driving the moving rod to slide in the annular groove, and the roller drives the moving rod to reciprocate horizontally. , thereby driving the screen frame to sieve the rice, improving the filtering effect, reducing the possibility of large sand and gravel getting stuck in the hulling roller, and the hulling is carried out by the hulling roller. The fan blows the rice husk to one side, thereby moving the feeding pipe out, which is convenient for the separation of rice and husk and the operation of the staff. At the same time, the dual-axis motor drives multiple mechanisms to operate at the same time, greatly reducing the manufacturing cost. However, during the storage of rice raw materials, a certain amount of moisture will accumulate in the rice husk, resulting in the rice husk always adhering to the surface of the rice during the hulling process. It is difficult to dry the rice in advance when using the above technical solution, which reduces the work efficiency and affects the effect of rice hulling.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a rice processing hulling device is provided to achieve a more practical purpose. Utility Model Content
