AI Technical Summary
In the existing tea processing technology, tea leaves are prone to entrain impurities such as dust, sand, and green and yellow leaves, resulting in low tea sorting efficiency and easy blockage of screens, affecting the efficiency of tea falling into it.
A tea air selection and removal device for tea processing is designed, including air selection box, spiral plate, feed inclined plate and fan. The tea leaves are continuously transported to the feeding inclined plate by rotating the spiral plate. The airflow blown by the fan blows out the impurities in the tea leaves and fall into different tanks respectively. At the same time, an anti-blocking mechanism is set up to prevent the screen plate from being blocked through intermittent movements of the limit block and the strike block.
This device can effectively remove impurities in tea, improve the efficiency and accuracy of tea sorting, avoid the problem of screen clogging, and improve the quality and efficiency of tea processing.
