Description

Technical Field

[0001] The utility model relates to the technical field of rice sorting, in particular to a rice particle size sorting device. Background Art

[0002] Rice is a food made from paddy rice after processes such as cleaning, husking, milling, and finished product sorting. The rice processed after rice planting and harvesting will have some differences in grain size. Before being packaged and sold, broken rice needs to be screened and removed, and rice of different grain sizes has different prices. Rice particle size sorting equipment is used to screen and remove broken rice and sort rice of different grain sizes.

[0003] After searching, the existing Chinese patent with publication number CN202320157126.4 discloses a rice processing and grading device, in which small-sized rice grains are first screened out through the first grading area, and the small-sized rice grains are discharged out of the box through the first discharge valve and are centrally packaged, and then the medium-sized rice grains are screened out through the second grading area, and the medium-sized rice grains are discharged out of the box through the second discharge valve and are centrally packaged, and finally the large-sized rice grains are screened out through the third grading area, and the large-sized rice grains are discharged out of the box through the third discharge valve and are centrally packaged, while the unscreened rice grains are extra-large-sized rice grains, and the extra-large-sized rice grains are discharged out of the box through the fourth discharge valve and are centrally packaged, thereby avoiding the mixing of large and small rice grains in rice packaging and greatly improving the efficiency of rice grading processing.

[0004] The above technical solution has the following defects: although such rice particle size sorting equipment can sort rice of different particle sizes through multiple groups of sieves in the grading area, in actual use, only the flat sieve is used to screen the rice, the contact surface is limited, and the rice will be transferred to the next grading area after the transmission rod is rotated. In order to further improve the sorting effect of the rice particle size, a rice particle size sorting equipment is proposed, in which a cylindrical sieve net is provided to grade and screen the rice particles. The cylindrical structure enables the rice to contact with the sieve cylinder more fully, improves the screening efficiency, and is easy to disassemble and replace. The sieve cylinders with different apertures can be selected for graded screening according to needs, thereby further improving the applicability of the rice particle size sorting equipment.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.
