Bean particle sorting device

Abstract

The invention relates to a food particle sorting device, in particular to a bean particle sorting device. The bean particle sorting device comprises a conical sieve and three containers, wherein the containers are arranged below the sieve; the center of the sieve is connected with a power output shaft of a motor; the mesh surface of the sieve is divided into two concentric annular sieves by taking the center of the sieve as the reference; the meshes of each annular sieve are sequentially enlarged from inside to outside; the three containers are arranged at the projection positions of the two annular sieves and the outer edge of a larger annular sieve respectively; a feeding hopper and a conveying belt are further arranged above the sieve; the conveying belt is downwards arranged obliquely; pits which are used for increasing friction force are formed in the working surfaces of the conveying belt; the lower end of the conveying belt is positioned above the center of the sieve; the upper end of the conveying belt is positioned outside the sieve; the upper working surface of the conveying belt moves from the lower end to the upper end. According to the scheme, the sorting device is capable of sorting small stones and sieving bean particles according to the size.

Description

technical field [0001] The invention relates to a grain sorting device, in particular to a bean sorting device. Background technique [0002] Dried bean curd is a flavored leisure food made from soybeans mixed with other raw materials. It is made by the following processes: pulping, slag removal, pulp cooking, paste preparation, powder testing, paste powder mixing, kneading and marinating, massaging, Briquetting and cooking. The refining process is to soak soybeans of uniform particle size and mix with water, and then grind and beat. An important process involved in this is the sorting of soybean grains, because small stones may be mixed in the soybean grains. If the small stones cannot be sorted out, it will cause serious damage to the beating device, and the crushed stones will enter the pulp. The material also has a great influence on the quality of the final dried tofu. In addition, the size of the soybean particles is less uniform, and soybeans with different particle...

Problems solved by technology

[0003] At present, the sorting methods for soybeans are mostly manual sorting and mesh screening, both of which have the problem of low efficiency, especially manual sorting is time-consuming and laborious, and cannot meet the production requirements, while mesh sorting cannot be very efficient. Good to separate small rocks of similar size from soybeans, still not meeting production requirements
