Description

Prickly ash sieving mechanism

Technical Field

The invention belongs to the technical field of pepper screening equipment, and particularly relates to a pepper screening device.

Background

The zanthoxylum bungeanum is mainly produced in Gansu, Sichuan, Shaanxi, Henan, Hebei, Shanxi, Yunnan provinces and other provinces in China, and compared with the zanthoxylum bungeanum produced in Gansu, Sichuan and Shaanxi, the zanthoxylum bungeanum has better quality. The wild pepper has many producing areas and varieties, so the wild pepper has inconsistent particle sizes. Before the pepper is eaten, impurities in the pepper are removed through multi-stage screening.

At present, the screening and separation of the peppers in the industry are mainly realized by combining the shape selection of a color selector and the manual selection. When the color selector is used for screening, the color selector blows inconsistent materials into a defective bin through an air blowing pipe according to the shapes of the peppers and the colors of the peppers stored in a computer chip of the color selector when a probe identifies the materials inconsistent with the shapes and the colors of the peppers, the materials consistent with the shapes and the colors of the peppers enter a finished product bin and flow into the next process, and in the screening process, as the pepper particles are small, the speed is high when the pepper passes through a color selection back plate of the color selector, when the probe identifies the materials inconsistent with the colors and the shapes of the peppers, the air blowing pipe is easy to cause mistaken blowing, the matching degree of the accuracy and the accuracy is poor, namely the peppers are blown into the defective bin, and the pepper spines or other foreign matters enter the finished product bin, finally, the pepper spines or other foreign matters are still contained in the finished product, so that the screening effect is not achieved, and the quality of the; when manual selection is adopted, workers are required to select one by one manually, more selection personnel are required, the selection time is longer, the selection productivity is lower, and meanwhile, visual fatigue is easily caused by observing the zanthoxylum bungeanum and the zanthoxylum bungeanum thorn by naked eyes under a long-time selection state, so that the zanthoxylum bungeanum thorn is mixed into a finished product, the selection effect cannot be achieved, and the quality of the finished product is influenced.

Therefore, the pepper screening device with high screening precision and high screening efficiency is urgently needed.
