Description

Technical Field

[0001] This utility model relates to the technical field of black tea processing equipment, specifically a black tea drying device. Background Technology

[0002] Black tea is a fully fermented tea, made from suitable new buds and leaves of tea trees through a series of processes including withering, rolling, fermentation, and drying. Fermentation causes chemical reactions in the tea leaves, resulting in a deep red color in the brewed tea, hence the name "black tea." Drying is the final step in black tea processing. The fermented tea leaves are then baked at high temperatures to rapidly evaporate the moisture, achieving the required dryness for preservation. This process also quickly deactivates enzymes, halting the fermentation process.

[0003] In existing technologies, black tea drying typically uses a dryer. The dryer usually has a rack inside where the black tea is laid flat on bamboo sieves, which are then placed on the rack. During drying, the rack rotates at a constant speed, blowing hot, dry air out from one side and expelling it into the air from the other side, thus achieving drying. However, existing dryers require bamboo sieves to be placed in and removed one by one during loading and unloading, which is inefficient. Furthermore, the hot air enters from one side, cools and increases in humidity after passing over the material, and is then sucked out from the other side, resulting in a long overall path. Although the rotating rack can rotate the material and ensure even heating, the middle section is far from the air outlet and obstructed by the rack and bamboo sieves, causing moisture to easily accumulate and affecting the drying effect.
