Tea leaf drying device allowing speed to be adjusted

Abstract

The invention provides a tea leaf drying device allowing the speed to be adjusted. The tea leaf drying device comprises a drying airflow blowing device (5) of bilateral symmetry in structure. 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 and 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 channels (51) uniformly distributed in the axial direction are formed in the annular body part (53) so that airflow can be input in the radial direction of the cylindrical blowing and drying channel (50).

Description

technical field [0001] The present application relates to the field of drying devices, in particular to a speed-adjustable tea drying device. 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 surface of the tea leaves.
