Tea leaf classified drying machine

Abstract

The invention relates to the technical field of tea leaf processing, and discloses a tea leaf classified drying machine. The tea leaf classified drying machine comprises a machine frame, wherein a drying box body is connected to the machine frame in a swinging manner; a first mesh screen, a second mesh screen and a third mesh screen are sequentially in slip connection to the inner part of the drying box body from top to bottom, wherein hole diameters of the first mesh screen, the second mesh screen and the third mesh screen are sequentially reduced; springs are connected between the third meshscreen and the bottom wall of the drying box body; a heating element is arranged on the top wall in the drying box body; a wind guiding chamber which communicates with the drying box body and a windsupplying box which communicates with the drying box body through the top wall of the drying box body are arranged on the machine frame; an air outlet is formed in the wind guiding chamber; a turbineis rotatably connected to the inner part of the wind guiding chamber; a first cam which is propped to the third mesh screen and a driving mechanism for driving the drying box body to swing are coaxially connected to the turbine; a first push rod which is propped to the first mesh screen is fixedly connected to the second mesh screen; and a second push rod which is propped to the second mesh screenis fixedly connected to the third mesh screen. Through the adoption of the tea leaf classified drying machine disclosed by the invention, classified drying and collecting of the tea leaves can be realized.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a tea grading dryer. Background technique [0002] In the processing and production of tea, drying is an extremely important process, which directly affects the quality of finished tea. The traditional tea drying method mostly uses an oven to dry the tea leaves. Put the tea leaves to be dried into the oven and heat the oven to evaporate the water inside the tea leaves after being heated. Usually, the tea leaves are in a static state in the oven. This kind of drying method takes a relatively long time to dry, and it is easy to cause the problem of uneven drying. [0003] In order to solve the above problems, drum drying is adopted in the prior art, and the tea leaves are put into the drum, and the drum is driven to rotate during the drying process. When the drum rotates, the tea leaves will be driven to rotate, so that the tea leaves can achieve the effect of stirring, so ...
