Potato cleaning and multi-grade quality sorting line

Abstract

The invention discloses a potato cleaning and multi-grade quality sorting line. The potato cleaning and multi-grade quality sorting line sequentially comprises a first lifting device, a soil removingdevice, a size grading device, a sorting device and a weighing and sorting device. Surface cleaning is conducted on potatoes through the soil removing device, then the potatoes enter the size gradingdevice to be graded according to the diameter, the potatoes with the small size and the potatoes with the large size in the potatoes are sorted out according to the preset size, the rest of the potatoes enter the sorting device, the potatoes enter the weighing and sorting device one by one after being sorted by the sorting device, and the potatoes are divided into a plurality of grades according to the weight through the weighing and sorting device. According to the potato cleaning and multi-grade quality sorting line, soil removing, size grading, weighing and quality sorting are combined, thepotatoes in various shapes are accurately sorted, the grading efficiency and the grading accuracy are greatly improved, multi-grade efficient sorting of the potatoes is achieved, and the potato cleaning and multi-grade quality sorting line is suitable for warehousing storage, direct fresh selling, later-period fresh cleaning processing and the like.

Description

technical field [0001] The invention relates to the technical field of potato sorting, in particular to a potato cleaning and multi-grade quality sorting line. Background technique [0002] At present, the sorting of potatoes mainly adopts size sorting methods, such as vibratory screening and roller bar gap sorting. Vibratory screening uses a sieve plate structure with mesh holes. The sieve plate is driven by a swing arm or a vibrating motor to achieve the purpose of multi-stage sorting; the roller gap sorting method is to separate the potatoes according to the size of the gap formed between the two roller bars. Vibration screening It is suitable for the sorting of miniature potatoes and seed potatoes, but not suitable for multi-stage sorting of commercial potatoes; the roller gap sorting method is usually only suitable for sorting round or quasi-round potatoes, and it is difficult for potatoes with irregular shapes. Realize accurate sorting. In reality, the roller bar gap...

Problems solved by technology

[0003] For this reason, in order to solve the high requirements for potato shape sorting by diameter in the commercial processing of potatoes, it is necessary to meet the requirements of round or quasi-round potato shape. For the potato system, there are different potato shapes, which will cause large errors in diameter sorting, which is difficult. Realize fine sorting, thereby restricting the value increase of potatoes. The invention provides a potato cleaning and multi-grade quality sorting line, which is not limited by potato shape and can be directly applied to the commercial treatment of potatoes harvested in the field. It is suitable for various sizes Potato grade sorting makes potatoes more versatile
