Description

Technical Field

[0001] This utility model relates to the field of tea withering technology, specifically a withering device for tea production. Background Technology

[0002] Withering equipment in tea production is mainly used in the first step of tea processing—withering. Its purpose is to control temperature, humidity and ventilation to make fresh leaves lose some moisture, soften the leaves, promote the transformation of internal substances, and lay the foundation for subsequent processes.

[0003] Chinese patent disclosure (CN221468929U) discloses a tea leaf aroma-enhancing and temperature-controlled withering device. The device includes a withering trough with a screen plate inside. A cold air fan and a hot air fan are installed on the inner wall of the withering trough, both electrically connected to an automatic temperature control computer board. The automatic temperature control computer board is installed on the operating side of the withering trough. A mesh screen is laid on the screen plate, and the ends of the mesh screen are connected to the wall of the withering trough by fixing clips. Tea leaves are evenly spread inside the mesh screen. This invention can precisely control temperature and airflow, improving tea quality and yield while reducing production costs.

[0004] However, it still has the following drawbacks: the device uses a hot air blower to blow hot air upwards to evaporate the moisture in the tea leaves, but the device cannot turn the tea leaves, resulting in uneven evaporation of moisture and poor withering effect on thicker parts of the tea leaves. Therefore, we propose a withering device for tea production to solve this problem. Utility Model Content

By setting up the filter cylinder, the first filter screen and the drying rod, it is convenient to remove impurities and humidity from the air.

[0012] A further improvement is that the flipping part also includes a mounting bracket, a gear, a C-shaped plate, and a toothed ring. The C-shaped plate is slidably fitted onto the outer surface of the placement shell, and the outer surface of the C-shaped plate is fixedly connected to the inner wall of the U-shaped frame. A cover plate is fitted onto the outer surface of the front end of the placement shell. By setting the C-shaped plate, it is convenient to install the placement shell.

[0013] A further improvement is that a slot is provided on the outer surface of the placement shell, and the outer surface of the elastic clip extends into the slot and engages with the inner wall of the slot. By providing the elastic clip, it is easier to position the placement shell.

[0014] A further improvement is that the mounting bracket is fixedly sleeved on the outer surface of the motor output shaft, and the mounting bracket is rotatably sleeved on the outer surface of the shaft through the second bearing. By setting up the motor and the mounting bracket, it is easier to control the rotation of the placement shell, so that the tea leaves are heated more evenly.

[0015] A further improvement is that the gear is fixedly sleeved on the outer surface of the rotating shaft, and the back of the gear ring is fixedly connected to the inner wall of the box. By setting the gear and gear ring, the motor drives the placement shell to rotate, and the placement shell rotates on its own axis, turning the tea leaves.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This withering device for tea production, by setting up a motor, mounting frame, second filter screen, placement shell, elastic clip, gear, rotating shaft, U-shaped frame, C-shaped plate and gear ring, when the motor is started, the mounting frame drives the placement shell to rotate, and at the same time the gear rolls along the outer surface of the gear ring, causing the rotating shaft and placement shell to rotate, continuously shaking and turning the tea leaves, making the tea leaves more evenly heated. The C-shaped plate and elastic clip facilitate the installation and positioning of the placement shell. By setting up a heating pipe, air pump, return pipe and shell, when the air pump and heating pipe are started, hot air flows upward to wither the tea leaves. The return pipe absorbs the hot air, reheats it, and then discharges it back into the box, improving energy utilization. By setting up a first filter screen, drying rod, filter cylinder and mounting plate, the filter cylinder facilitates the collection of tea dust, and the drying rod absorbs moisture from the air.
