A tea drying device with an airflow filter

Abstract

The invention relates to a tea drying device with an airflow filter screen, comprising a drying airflow blowing device (5) in bilateral symmetry in structure, wherein the drying airflow blowing device (5) comprises an annular body part (53) and an annular shell part (54); the annular body part (53) is provided with a cylindrical blowing drying channel (50) extending along the axial direction; the annular shell part (54) is supported on the annular body part (53) by a radial support (58) and used for containing the annular body part (53); a plurality of radial blowing airways (51) uniformly distributed in the axial direction are arranged in the annular body part (53) so as to input the airflow along the radial direction of the cylindrical blowing drying channel (50).

Description

technical field [0001] The application relates to the field of drying devices, in particular to a tea drying device with an airflow filter. Background technique [0002] In some drying machinery fields, especially in the field of tea drying machinery, air blow drying is often used to blow 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 the entire periphery of the tea conveyor belt. [0003] However, for the tea leaves in the whole drying process, the distribution of the moisture is often uneven, which often wastes more time for drying all the tea leaves for a drying device with uniform air blowing. . Moreover, such uniform 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 surface of the tea leaves.

AI Technical Summary

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
