[0002] There are many processes in tea production and processing, and different processes are required for different varieties of tea, including but not limited to drying, withering, fermentation, etc. The drying and withering processes are completed by heating the tea leaves. When using existing drying equipment, it is necessary to open the box door to take out the tea trays that have been dried, and then put in the tea trays that need to be dried. In this process, the hot air in the drying equipment will escape, and the newly entered cold air needs to be reheated to reach the set temperature during subsequent drying. The time used for the drying process is determined according to the amount of tea. When the drying time is short, the box door needs to be opened frequently, so the energy consumption is large.
