technical field

The utility model relates to the technical field of tea processing equipment, in particular to an energy-saving tea drying machine.

Background technique

Drying is an important operation process in tea production. Usually, the tea leaves are placed in a dryer, and the hot air is used to remove moisture from the tea leaves to achieve the purpose of drying. Commonly used dryers adopt a stacked structure, and the hot air is dried layer by layer from bottom to top. However, after drying the lower layer, the hot air has water vapor, which affects the drying effect of the upper layer when drying the upper layer. The tea leaves in the machine are generally in a piled state, so they will be heated unevenly and need to be turned manually. At this time, a large amount of tea dust will be generated, which will float out of the dryer with the hot air and fall on the machine equipment, affecting the quality of the machine equipment.
