Description

Technical Field

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

[0002] Tea, one of the world's most popular beverages, carries a rich cultural heritage and carries significant health benefits. Based on factors such as the degree of fermentation, production process, and origin, tea can be categorized into six main types: green tea, black tea, oolong tea (qingcha), white tea, yellow tea, and dark tea. Black tea is a fully fermented tea characterized by withering, rolling, fermentation (also known as "red change"), and drying. These processes result in a vibrant red or deep crimson tea infusion, a rich and lingering aroma, and a mellow taste with sweet or fruity notes.

[0003] The drying process of black tea is one of the key links in the production process of black tea. Drying can terminate enzyme activity, reduce moisture content and develop aroma, which has a vital impact on the quality and taste of black tea. There are two main methods of drying black tea: natural drying and mechanical drying. Natural drying is sun-drying black tea, but this method is greatly restricted by weather conditions, and the drying effect is not as stable as mechanical drying. Therefore, in modern black tea production, mechanical drying has become the mainstream method. However, traditional black tea mechanical drying equipment usually adopts stir-frying or tray drying, which has the disadvantage of inconvenience in collecting tea leaves. Therefore, the present application provides a black tea production drying device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a black tea production and drying device to solve the problem of inconvenience in collecting black tea during the existing black tea drying process.

[0006] A black tea production and drying device includes a drying cabinet, an electric heating wire mesh is installed on the inner side wall of the drying cabinet, a drying rack is installed in the drying cabinet, and the drying rack includes a shaft installed vertically and rotatably in the drying cabinet, a cantilever arranged on the top side wall of the shaft, and a hollow shell detachably assembled at the bottom of the cantilever, multiple cantilevers are radially distributed around the shaft, and a drive motor for driving the shaft to rotate is installed on the top of the drying cabinet.

[0007] Optionally, the hollow shell includes a frame and partition nets arranged on both sides of the frame, and an opening is opened at the top of the frame.

[0008] Optionally, the frame is configured as a flat structure.

[0009] Optionally, a handle is provided on a side of the frame away from the shaft.

[0010] Optionally, a sleeve block is sleeved on the shaft near the top end, and the plurality of cantilevers are integrally connected to the sleeve block.

[0011] Optionally, a sleeve is provided at the top of the sleeve block, the sleeve block and the sleeve are movably sleeved with the shaft rod, and the sleeve is fixedly connected to the shaft rod by bolts.

[0012] Optionally, a rail groove is provided at the bottom of the cantilever, and the top of the frame body is slidably engaged with the rail groove.

[0013] Optionally, a first limiting ridge is provided at the bottom of the inner side wall of the rail groove, and a second limiting ridge is provided at the top end of the outer side wall of the frame body, which can be embedded between the first limiting ridge and the inner top wall of the rail groove.

[0014] Optionally, the cantilever is provided with an exhaust slot, and a plurality of the exhaust slots are provided at equal intervals.

[0015] Optionally, the front end face of the drying cabinet is hingedly equipped with a cabinet door, the cabinet door is provided with a transparent observation window, and the bottom of the rear end face of the drying cabinet is equipped with an exhaust fan for exhausting the air in the drying cabinet to the outside.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, a drying rack is arranged in the drying cabinet, and dried black tea is loaded into multiple hollow shells. The electric heating wire mesh is energized, and the drive motor is started to drive the shaft to rotate at a constant speed. The shaft drives multiple hollow shells filled with black tea to rotate at a constant speed in the drying cabinet through the cantilever. In this way, the black tea can be heated as evenly as possible for drying, thereby improving the drying efficiency and the drying effect of the black tea.

[0018] Through the sliding connection between the frame and the cantilever, the frame can be separated from the cantilever by pulling the handle. At this time, the black tea to be dried can be put into the hollow shell composed of the frame and the partition through the opening, or the dried tea in the hollow shell can be collected. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
