Problems solved by technology

[0004] The technical problem solved by the present invention is to overcome the defects of the separation of shelled buckwheat and shelled buckwheat and the low secondary shelling rate in the existing buckwheat processing process, and the buckwheat contains a small part of buckwheat husk, buckwheat and The mixture of hulled buckwheat is firstly screened through the vibrating grading sieve A equipped with upper and lower screens, using the particle size difference between hulled buckwheat and buckwheat and automatic grading characteristics, with the help of a screen with suitable mesh and movement form For the first paddy separation, the buckwheat husks are sent to the collection bin of the air net system by the suction type vertical suction separator; The material is broken buckwheat and dust, and enters the collection bin; the material on the lower screen is mainly buckwheat and some small-grained buckwheat with shells, and this part of the mixed material enters the color sorter through the elevator for color separation and separation. The shelled small-grained buckwheat is mixed with the upper sieve (large-grained shelled buckwheat) and then enters the shelling machine for secondary shelling. The separated qualified pure buckwheat continues to be used in two layers. The vibrating grading sieve B of the sieve is screened, and the broken buckwheat and light impurities are separated again to produce high-purity and high-quality buckwheat products

Abstract

The invention discloses a material grain separation technology used after shelling shells during processing of buckwheat. The technology comprises the steps that 1, after the shells of the buckwheat are separated, a mixed material containing a small part of buckwheat husks, buckwheat grains and the buckwheat with the shells is screened through a vibration grading screen at first, oversize products on lower layer screen cloth enter a color sorter through an elevator and the colors of the oversize products are sorted and separated, color sorting is conducted three times sequentially, separated semi-finished buckwheat grains are screened and graded through the vibration grading screen, and high-quality finished buckwheat grains are obtained; 2, small-grain-type buckwheat with the colors being sorted for the first time and the second time is uniformly mixed with large-grain-type buckwheat intercepted by upper layer screen cloth, wherein the small-grain-type buckwheat and the large-grain-type buckwheat are provided with the shells, and after cooling-heating treatment is conducted, the buckwheat enters a huller in batches for secondary shelling; and 3, the final material grain separation rate reaches 99.9%, the secondary shelling rate reaches 95%, the purity of the buckwheat grains can reach 99.9%, the imperfect grain mass is 1% or less, impurities account for 0.10% or less, broken grains account for 1% or less, the surface of the buckwheat is bright and clean, and the buckwheat has obvious buckwheat fragrance. The purpose of large-scale material grain separation with high quality, high efficiency and high yield is achieved for the buckwheat grains with the shells being separated.

Description

technical field [0001] The invention relates to buckwheat processing, in particular to a material particle separation process after shelling in the buckwheat processing process. Background technique [0002] Buckwheat belongs to the dicotyledonous Polygonaceae, buckwheat genus, its growth period is short, suitable for growth in cold climate environment, commonly known as jade wheat, triangle wheat, rye wheat, is a very ideal miscellaneous grain crops. Because of its unique nutritional value, it has been paid more and more attention by people. However, based on the characteristics of buckwheat such as small size, strong shell toughness, large kernel brittleness, and small gap between kernel and shell, coupled with the limitations and imperfections of the mechanical properties of the existing buckwheat shelling machine, the existing shelling machine is used for its It is very difficult to shell the buckwheat. The chaff cannot be completely removed after the buckwheat is shell...
