Description

Swing Tea Dryer

technical field

The invention relates to the technical field of tea processing, in particular to a swing-type tea drying machine.

Background technique

Drying in tea processing is a key process that determines the quality of finished tea. In the existing mesh belt tea continuous drying equipment, the hot air is blown directly from one end of the drying chamber to the mesh belt containing the tea leaves, resulting in a high temperature of the hot air near the hot air inlet, and a low temperature of the hot air at the end far away from the hot air inlet. Uneven heating affects the quality of tea leaves; the temperature of the hot air used for drying is generally 100-140°C. After the hot air passes through the tea leaves on the mesh belt, the temperature is still high, generally up to 80-100°C, and is directly emitted to the outside. cause a large amount of heat loss. At the same time, the hot air source contains a certain amount of water that has not been removed, which affects the drying effect.
