Peanut finishing classification screening machine and screening method thereof

Abstract

The invention relates to a peanut finishing classification screening machine and a screening method thereof. The machine comprises a base plate, a feeding device, a screening device and a sorting device; the screening device is mounted on the left side of the upper end of the base plate; the feeding device is arranged on the left side of the upper end of the screening device; the sorting device ismounted on the right side of the upper end of the base plate; and the sorting device is positioned on the right side of the screening device. The machine can solve the difficulties of weak screeningeffect during screening of peanuts by a traditional peanut screening machine, incapability of accurately classifying the peanuts, incapability of singly separating out broken peanuts, easy blockage ofelliptic peanuts on a screening plate during screening and influence on the screening effect, can achieve a function of automatically classifying and screening the peanuts, is excellent in screeningeffect, can accurately classify the peanuts, meanwhile, can singly separate out the peanuts broken to pieces, can prevent the peanuts from blocking the screening plate, and achieves excellent screening effect.

Description

technical field [0001] The invention relates to the field of peanut processing equipment, in particular to a peanut finishing grading and screening machine and a screening method thereof. Background technique [0002] Peanut, also known as groundnut, belongs to Papilionaceae. Groundnut is an annual herb plant, native to South America. There are more than 100 countries that cultivate peanuts in the world. It is the most common in Asia, followed by Africa. According to the literature on peanuts in China According to records, the cultivation history is more than one hundred years earlier than in Europe. Peanuts are known as "vegetable meat". The oil content is as high as 50%. [0003] When peanuts are refined, there are usually the following defects: 1. When screening, the screening effect is poor, and the peanuts cannot be accurately graded and screened, which affects the quality of finishing; 2. During the screening process, the oval peanuts It is easy to get stuck on the si...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a sorting and screening machine for peanut finishing and its screening method. The invention can solve the problem that the existing peanut screening machine has poor screening effect and cannot accurately screen peanuts. The grading can not separate the broken peanuts separately, and when sieving, the oval peanuts are easy to get stuck on the sieving board, which affects the screening effect and other problems. It can realize the automatic grading and screening function of peanuts. It has the advantages of good screening effect, accurate grading of peanuts, separate separation of broken peanuts, and good screening effect by preventing peanuts from blocking the screening plate.
