AI Technical Summary
Traditional tea rolling machines suffer from uneven pressure and extrusion during tea processing, resulting in excessive tea damage and breakage, and thus poor performance.
The screw device adopts a variable pitch rotating blade design. The spacing between the rotating blades is larger near the feed end and gradually decreases near the discharge end. A reverse thread blade is set at the discharge end to achieve uniform kneading of tea leaves and convenient discharge.
This process achieves uniformity and efficiency in tea rolling, reduces tea damage, and improves tea quality and production efficiency.
