[0006] Furthermore, a heat-insulating layer is provided on the inner wall of the drying box to reduce heat loss.

[0007] Furthermore, it also includes a first conveying platform located at the front end of the first drying box and a second conveying platform located at the rear end of the third drying box.

[0008] Furthermore, the first conveying platform and the second conveying platform are both belt conveyors.

[0009] Furthermore, the first transition conveying mechanism includes a first support, a second roller and a second roller frame; the second transition conveying mechanism includes a second support, a third roller and a third roller frame.

[0010] Furthermore, the heating wire includes a first heating wire arranged in the first drying box, a second heating wire arranged in the second drying box and a third heating wire arranged in the third drying box, the heating temperature of the first heating wire is 25°C, the heating temperature of the second heating wire is 28°C, and the heating temperature of the third heating wire is 35°C.

[0011] Furthermore, it also includes a tray for holding tea leaves; ventilation holes are arranged at the bottom of the tray, and handles are arranged at both ends of the tray.

[0012] Furthermore, there are four fans, which are evenly arranged above the interior of the drying box.

[0013] Furthermore, the inlet and outlet of the drying box are both provided with sealing doors for closing the drying box during the tea drying process.

[0014] Furthermore, the tray is made of stainless steel.

[0015] The tea drying device of the utility model has the following technical effects:

[0016] This drying device has high drying efficiency. The first drying box is a low-temperature drying box. In the initial stage of drying, the temperature is controlled below 25°C. This stage is mainly to promote the proper activity of enzymes in the tea leaves and help the formation of the color and aroma of the tea leaves. The second drying box is a medium-temperature drying box. The temperature is controlled at 28°C to make the tea leaves further lose water and form a unique flavor. The third drying box is a high-temperature drying box. The temperature is controlled at 35°C to ensure that the tea leaves reach an appropriate degree of dryness and prevent mildew. At the same time, the shape and aroma of the tea leaves are fixed. By setting drying boxes with different temperatures, continuous production of the entire drying process of the tea leaves can be achieved, effectively avoiding repeated temperature adjustments in the drying boxes and reducing drying efficiency. A fan is provided on the top of the drying box to keep the heat in the drying box evenly distributed, which helps to evenly disperse the moisture and avoid local overdrying or overwetting.
