AI Technical Summary

Technical Problem

Tea leaves are mainly affected by the airflow at the lower end of the conveyor belt. As the tea leaves are piled up, the airflow effect on the upper tea leaves is small, and the moisture evaporation of the lower tea leaves is affected. The tea leaves inside the pile are covered up, which affects the withering efficiency and quality.

Method used

Design a continuous tea spreading device, including a lower ventilation module pool, a spreading conveyor unit, and a turning component. Uniform airflow is provided by front and rear ventilation fans and an upper perforated mesh plate. The turning component turns the tea leaves to ensure that each part of the tea leaves is in full contact with the air. Combined with the design of ventilation holes and turning plates on the conveyor belt, continuous tea spreading is achieved.

Benefits of technology

This improved the quality and efficiency of tea spreading, ensured the uniformity of tea leaves, avoided uneven evaporation of moisture inside the tea pile, enabled continuous tea production, reduced manual intervention, and improved production efficiency.

Abstract

This utility model discloses a continuous tea-spreading device, relating to the field of tea processing. It addresses the problem in existing technologies where tea leaves on a conveyor belt are primarily affected by the airflow at the lower end, resulting in the upper tea leaves receiving less airflow due to overlapping, which also affects the evaporation of moisture from the lower tea leaves and causes the tea leaves inside the pile to become suffocated. Multiple lower feeding rollers are connected to a common conveyor belt. Several outer fixing strips are evenly arranged at the front and rear ends of the conveyor belt. Inside the fixed frame, a turning assembly is arranged along the upper end of the conveyor belt. The turning assembly includes a central rotating roller, whose central shaft is rotatably connected to the fixed frame via bearings. Outer fixing plates are evenly arranged at the front and rear ends of the central rotating roller, and these plates are drive-connected to the outer fixing strips. Tilting plates are arranged from front to back between two sets of outer fixing plates on the exterior of the central rotating roller.
