Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a continuous tea drying device. Background Art

[0002] The tea making process is generally divided into the steps of withering, killing green leaves, rolling, deblocking and drying. The rolling process will produce juice, which will cause the tea leaves to clump together. The tea leaves need to be separated as soon as possible and the temperature needs to be lowered quickly to avoid the production of stuffy smell and insufficient drying, which will cause stuffy sourness. Therefore, the tea leaves need to be dried.

[0003] Patent document CN211211271U discloses a continuous tea drying device. It includes a base, a conveyor belt body, a conveyor belt support frame, a fan, and a heating device. The device evenly arranges tea leaves on the conveyor belt body, allowing them to move at a constant speed toward the end of the conveyor belt body. During the conveying process, the fan blows air upward, which is heated by the heating device to form hot air, drying the tea leaves on the conveyor belt.

[0004] When the continuous tea drying device proposed in the above patent document is actually used, the tea leaves need to be spread flat on the surface of the conveyor belt. However, the tea leaves need to be spread flat on the surface of the conveyor belt manually. Once uneven spreading occurs, the tea leaves will accumulate to a certain extent, which will cause uneven drying of the tea leaves and lead to insufficient drying of the tea leaves. In addition, the drying device cannot remove impurities from the tea leaves while drying, which is not conducive to improving processing efficiency. Utility Model Content
