AI Technical Summary
In existing tea granulation equipment, tea particles are uneven in size and density, making them prone to breakage and affecting product quality.
The system uses a spiral conveyor roller and a planetary gear set in conjunction with a pressure roller to achieve tight feeding of tea leaves. The particle size is controlled by a lifting and cutting mechanism, and a buffer spring is installed under the ring die to reduce impact.
This achieves uniformity in tea particle size and density, reduces the probability of particle breakage, and improves product integrity and quality consistency.
