Impurity removal device for soybean meal deep processing and production method thereof

Abstract

The invention discloses an impurity removal device for soybean meal deep processing and a production method thereof. The impurity removal device comprises a collecting box; supporting rods are hinged to the two ends of one side of the top of the collecting box; positioning frames are hinged to the top ends of the two supporting rods, and the top ends of the two supporting rods are hinged to the two ends of one side of the bottom of each positioning frame; and filter screens are arranged at the middles of the positioning frames. The two ends of the two sides of a positioning plate are connected with first positioning rods fixed to the middle positions of the tops of two positioning seats in a penetrating and inserting mode, so that the positioning plate drives the positioning frames hinged at one end to shake while moving up and down, and impurities roll into a discharging groove, an inclined plate in the discharging groove fixedly slides to the outer side, so that screened particles and impurities can be directly cleaned, cleaning can be conducted without stopping screening, the screening efficiency of soybean meal is improved, and the practicability of the impurity removal device for soybean meal deep processing is improved.

Description

technical field [0001] The invention relates to the field of impurity removal devices for deep processing of soybean flour, in particular to an impurity removal device for deep processing of soybean flour and a production method thereof. Background technique [0002] Soybean flour is made from defatted soybeans. Soybean flour not only has the characteristics of high soybean protein content and high unsaturated fatty acid content, but also has health effects such as anti-aging and brain-building. It is a food with high nutritional value. The method of obtaining defatted soybeans after proper heat treatment and flattening of soybeans, and then extracting oil with organic solvents. The defatted soybeans obtained by this method are granular, high in protein content, low in fat content, low in moisture, and easy to crush. The degree of protein denaturation mainly varies with the type of solvent and the method of separating defatted soybeans from the solvent. [0003] In the prio...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when small-scale soybean flour deep processing institutions process and produce soybean flour, they need to separate semi-finished soybean flour from partially ground soybean particles and their impurities. Therefore, the separation process is usually done manually. Screening with small devices leads to low working efficiency during sieving, and it is difficult to directly clean the sieved particles and impurities. It is necessary to stop the sieving several times to clean the impurities independently, which not only reduces the sieving efficiency of soybean flour, but also It is easy to make soybean flour difficult to sieve cleanly, so a kind of impurity removal device for deep processing of soybean flour is needed
