Description

Technical Field

[0001] The utility model relates to the field of sorting equipment, in particular to a circular cross sorting line. Background Art

[0002] In the process of deep processing of vegetables, vegetables need to go through a series of processing steps, including washing, removing impurities, cutting, etc., to ensure that they meet uniform quality standards. After these processes, the processed vegetables are usually conveyed to the sorting conveyor for sorting and packaging. At present, the sorting link in the deep processing of vegetables mainly relies on conveyor belts and sorting platforms.

[0003] However, the traditional vegetable sorting conveyor usually consists of multiple parallel and spaced conveyor belts and a sorting platform connected to the discharge end of the conveyor belts. This design takes up a lot of workshop space. Since deep processing of vegetables involves multiple processes, each process requires corresponding equipment and sites. The existing sorting conveyor has a large equipment footprint due to the parallel and spaced arrangement of multiple conveyor belts, and the workshop land becomes tight. This not only increases the cost of plant construction and operation, but also limits the expansion and optimization of production lines. In addition, the large-area equipment layout also increases the difficulty of workers' movement and operation, affecting work efficiency.

[0004] Secondly, garbage and dust generated during the sorting process are easy to accumulate, which may lead to secondary contamination of vegetables. During the processing and transportation of vegetables, dirt, dead leaves, residual sewage and other impurities on the surface will fall off and accumulate in every corner of the conveyor belt and sorting platform. These impurities not only affect the normal operation of the equipment, but may also become a breeding ground for bacteria and other microorganisms, thereby contaminating the sorted vegetables. Especially on the sorting platform, the surface that the vegetables are in direct contact with is prone to cross contamination if it is not cleaned in time. This secondary contamination problem not only affects the sorting effect and food quality, but also may bring serious food safety risks. In addition, the cleaning and maintenance of the equipment not only requires a lot of manpower and time, but may also cause the production line to stop, affecting the overall production efficiency.

[0005] Therefore, the existing vegetable sorting equipment needs to be further optimized and improved. Utility Model Content
