Tea drying device automatically controlled and provided with airflow filtering net

Abstract

A tea drying device automatically controlled and provided with an airflow filtering net comprises a drying airflow blowing device (5) which is structurally symmetric left and right. The drying airflow blowing device (5) comprises an annular body part (53) and an annular shell part (54), wherein the annular body part (53) is provided with a cylindrical blowing drying channel (50) extending in the axial direction, and the annular shell part (54) is supported on the annular body part (53) through a radial support (58) and contains the annular body part (53). A plurality of radial blowing air flues (51) evenly distributed in the axial direction are arranged in the annular body part (53) so that airflow can be input in the radial direction of the cylindrical blowing drying channel (50).

Description

technical field [0001] The present application relates to the field of drying devices, in particular to a tea drying device with automatic control and an airflow filter. Background technique [0002] In some fields of drying machinery, especially in the field of tea drying machinery, air blowing is often used to blow away the moisture away from the vicinity of the tea leaves. In order to ensure that the tea leaves are fully and evenly dried, air blowing openings are often evenly arranged on the entire circumference of the drying device to blow around the entire periphery of the tea conveyor belt. [0003] However, for the tea leaves during the entire drying process, the moisture distribution is often uneven, which often wastes more time to dry all the tea leaves for a uniform blowing drying device . Moreover, this uniform air blowing is often difficult to cause the tea leaves to be turned in a selected direction, and it is difficult to directly turn the side or bottom surf...

Problems solved by technology

[0003] However, for the tea leaves during the entire drying process, the moisture distribution is often uneven, which often wastes more time to dry all the tea leaves for a uniform blowing drying device

Moreover, this uniform air blowing is often difficult to turn the tea leaves in a selected direction, and it is difficult to directly turn the side or bottom surface of the tea leaves.

[0004] Moreover, due to the operating characteristics of the airflow and the large number of airflow channels, the blockage of the airflow channels is often easy to occur but not easy to be found, or not easy to be overcome or corrected immediately

This leads to quality defects in continuous production

Downtime for maintenance reduces productivity and incurs additional production costs
