[0002] During the processing of tea, tea leaves need to be dried in a tea dryer. Traditional tea drying equipment is generally a closed drying room, where the tea leaves are placed statically for drying. This type of drying equipment has a long drying cycle and is difficult to achieve continuous production. On the other hand, since the tea leaves cannot be turned over during the drying process, the degree of drying of the tea leaves is uneven, affecting the quality of the final product.

[0003] In this regard, after checking the publication number, CN211120275U discloses a continuous high-speed tea drying equipment, including a screw feeder, a continuous tea dehydration device and a dryer. The continuous tea dehydration device includes a base and a glass cover fixed on the base. The discharge port of the screw feeder is connected to the feed port arranged on the glass cover. A fan is arranged in the base, and the air outlet of the fan is connected to the bottom of the glass cover. A secondary heating device is also arranged at the bottom of the glass cover. A discharge pipe is also connected to the top of the glass cover. The dryer is composed of a feed cover arranged on the top of the dryer, a plurality of conveyor crawlers staggered in the dryer, and a plurality of heating plates arranged in the dryer. The discharge pipe is inserted into the feed cover and is located above the through hole. An independent hot air generating chamber is also arranged on the back of the plurality of heating plates. Each hot air generating chamber is connected to the air inlet of the fan through a connecting pipe, and each hot air generating chamber is also provided with an air inlet extending out of the outside of the dryer.

[0004] The above technology discloses a continuous high-speed tea drying device, which uses a screw feeder to transport tea into the dryer, and uses multiple conveying crawlers arranged up and down in the dryer to achieve conveying output and extend the tea conveying and drying time, and uses the free fall of tea to achieve a turning effect when it is transported to the next conveying crawler, which is convenient for continuous drying work.
