Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a circulating high-efficiency tea drying device. Background Technology

[0002] Depending on the type of tea, the tea production process varies, but it generally includes four basic steps: picking, fixing, rolling, and drying. Tea drying is mostly done using a drying machine. Most tea drying devices use a hot air blower to circulate hot air into the drying chamber to achieve the effect of drying the tea.

[0003] Currently, existing tea drying equipment uses a relatively simple drying method. The tea leaves are often fixed in place, and only one side of the tea leaves can be dried, resulting in uneven heating and low drying efficiency. In addition, the hot air from existing tea drying equipment is directly discharged after drying, without being recycled, leading to heat loss. Therefore, we propose a circulating high-efficiency tea drying device. Utility Model Content

[0013] This utility model provides a circulating high-efficiency tea drying device, which has the following beneficial effects:

[0014] 1. This circulating high-efficiency tea drying device, through the arrangement of a rotating shaft, gears, rack plate, connecting rod, sliding frame, sliding groove, stepper motor, turntable, and sliding pin, loads tea leaves into the drying mesh cylinder during the drying process. When drying, the stepper motor is turned on to drive the turntable and sliding pin to rotate. The sliding pin is slidably connected to the sliding groove, which in turn drives the rack plate to move up and down slowly through the sliding frame and connecting rod. When the rack plate moves up and down, it meshes with the gears, which in turn drives the rotating shaft and the drying mesh cylinder to rotate slowly back and forth. This allows the tea leaves in the drying mesh cylinder to turn over during the drying process, achieving uniform and efficient drying of the tea leaves.

[0015] 2. This circulating high-efficiency tea drying device, through the arrangement of air guide grilles, guide rails, air guide fans, and heating pipes, allows for efficient drying of tea leaves in the drying chamber. By turning on the air guide fan and heating pipes, heat is generated by the heating pipes and then blown into the drying chamber through the air guide grilles by the air guide fan. After drying, the air guide fan's input end exhausts air from the circulation chamber into the drying chamber, causing the air guide grilles on the other side of the partition to generate suction, drawing the dried hot air into the circulation chamber. The hot air is then dehumidified by the guide rails and blown back into the drying chamber by the air guide fan, thus achieving circulating drying and effectively preventing heat waste.
