Green tea drying device

Abstract

The invention belongs to the field of tea processing equipment, and discloses a green tea drying device comprising a rack and a drying oven fixed to the rack. The drying oven is provided with an air outlet, and internally provided with a heating mechanism, and the interior of the drying oven is slidably connected to sliding plates which are rotatably connected to a plurality of rotating shafts; cages are fixed to the rotating shafts, and each rotating shaft is fixedly provided with a link gear; the link gears on every two adjacent rotating shafts are engaged with each other, and the interior of the drying oven is rotatably connected to a main shaft which is fixedly provided with first cams; the first cams abut against the sliding plates, and the main shaft is fixedly provided with a driving gear, and the outer wall of the drying oven is fixedly provided with a hot air pipe; and a plurality of drying pipes are all connected to the hot air pipe, and provided with drying holes uniformly.Compared with the prior art, the green tea drying device has the advantages that drying is performed through rotation of the main shaft and lead-in of hot air alternately according to the scheme, andthe tea drying efficiency is improved; and the tea is dried more uniformly in the ceaseless turnover process, and the tea can be prevented from being broken due to violent movement.

Description

technical field [0001] The invention belongs to the field of tea processing equipment, in particular to a green tea drying device. Background technique [0002] At present, there are various methods for drying green tea. The prior art discloses a single-layer tea dryer, which includes a rectangular box body and a heating vibration screen arranged in the box body; It is composed of a driving device and a screen mesh composed of a plurality of heating wires that are staggered and connected to the power supply. The vibration driving device can drive the screen mesh to vibrate. The above drying equipment uses electric heating wire to heat and dry green tea. Although this method has high drying efficiency, if different grades of green tea are dried at the same time, it will lead to the mixing of high-grade green tea and low-grade green tea and reduce the grade. thereby reducing the market price. [0003] In order to solve the above problems, the Chinese patent application No. 2...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the problem of mixed drying of different grades of green tea in the prior art through the setting of drying plates, but there are still certain problems in the above scheme. The gas passes through several drying plates in turn from bottom to top to complete the drying process Green tea is dried, but the drying plate is still. On the one hand, the green tea cannot be turned over, and the green tea located in the middle of the tea pile on the drying plate will not easily contact with hot air, thereby reducing the drying efficiency; on the other hand, the drying After drying, the drying degree of the green tea near the bottom plate on the drying plate is greater than that of the green tea near the top plate on the drying plate, resulting in the problem of uneven drying degree of green tea.
