Description

Technical Field

[0001] This utility model belongs to the field of green tea processing technology, specifically relating to a green tea fixation processing device. Background Technology

[0002] Killing green is one of the initial processing steps for green tea, yellow tea, black tea, oolong tea, pu-erh tea, and some red teas. Its main purpose is to destroy and deactivate the oxidase activity in fresh leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols and other substances in fresh leaves, evaporate some of the moisture in fresh leaves, soften the tea leaves, make them easier to roll and shape, and at the same time remove the grassy smell and promote the formation of good aroma.

[0003] The common method of fixing tea leaves involves placing them in a rotating fixing pot, allowing the leaves to rotate and turn over while the pot is heated to process them.

[0004] During the withering process in the withering pot, the tea leaves are easily not stirred evenly, resulting in some tea leaves being over-withered and others under-withered. In addition, since green tea contains some sand and soil impurities, it is difficult to remove them effectively during the withering process, which increases the time required for later tea leaf sieving. At the same time, it is difficult to accurately control the withering temperature, which affects the quality and taste of green tea. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a green tea fixation processing device, including a frame, a fixation tank, a stirring device, an electric telescopic rod, and a controller.

[0006] The stirring device includes a drive motor, a rotating shaft fixedly connected to the output end of the drive motor, and a stirring fan fixedly connected to the side surface of the rotating shaft. A heating ring tube is fixedly connected to the inner side wall of the blanching tank, and a temperature sensor is fixedly connected to the inner side wall of the blanching tank. A filter plate is movably connected through the side surface of the blanching tank to the interior. A vertical plate is fixedly connected to the side surface of the blanching tank, and a sliding groove is provided on the side surface of the vertical plate. A T-shaped slider is movably connected inside the sliding groove. A connecting shaft is fixedly connected to the output end of the electric telescopic rod.

[0007] Through the above technical solution, the drive motor drives the stirring fan to rotate, causing the tea leaves to form a vortex in the fixation tank, which stirs the tea leaves and, together with the heating ring tube, achieves the fixation of the tea leaves. The temperature sensor monitors the temperature in real time and transmits the results to the controller. The controller adjusts the temperature of the heating ring tube in real time according to the information to avoid overheating and scorching of the leaves. The filter plate facilitates the discharge of impurities in the tea leaves during the fixation process and is detachable for discharging the tea leaves after fixation. The electric telescopic rod enables the fixation tank to swing in a fan shape around the shaft during stirring, helping to turn the tea leaves inside and making the stirring more uniform.

[0008] The present invention is further configured such that the drive motor is fixedly connected to the upper surface of the blanching tank, the side surface of the rotating shaft is rotatably connected to the blanching tank, and the upper surface of the blanching tank is provided with a feed inlet.

[0009] Through the above technical solution, the drive motor adopts an upper-mounted design to avoid direct contact with the high-temperature environment inside the blanching tank, which can effectively extend the service life of the motor. The feed port is used to add tea leaves into the blanching tank.

[0010] The present invention is further configured such that a shaft is rotatably connected through the side surface of the frame, one end of the shaft is fixedly connected to the blanching tank, and the controller is fixedly installed on the frame.

[0011] Through the above technical solution, the fixation tank is rotatably connected to the frame via a shaft, which can achieve tilt angle adjustment. During the fixation process, tilting the tank, together with the stirring device, makes the tea leaves tumble in a wave-like manner, resulting in a more uniform fixation effect.

[0012] The present invention is further configured such that a filter screen is fixedly connected to the inner side wall of the filter plate, and a discharge pipe is provided on the lower surface of the blanching tank, and a valve is provided inside the discharge pipe.

[0013] The above technical solution makes it easy to filter impurities in tea leaves and remove them.

[0014] The present invention is further configured such that a mounting bracket is fixedly connected to the side surface of the T-shaped slider, and the side surface of the connecting shaft passes through the mounting bracket and is rotatably connected to the mounting bracket.

[0015] Through the above technical solution, the T-shaped slider and the slide groove form a sliding pair, which, together with the electric telescopic rod, can realize the smooth swing of the blanching tank.

[0016] The present invention is further configured such that an extension frame is fixedly connected to the side surface of the frame, and the side surface of the extension frame is fixedly connected to an electric telescopic rod.

[0017] The present invention is further configured such that guide rods are symmetrically arranged on the side surface of the blanching tank, and guide grooves are arranged on the side surface of the frame, with the guide rods located within the guide grooves.

[0018] The present invention is further configured such that a handle hole is provided through the upper surface of the filter plate, a through groove adapted to the filter plate is provided on the side surface of the blanching tank, and the bottom inner wall of the blanching tank is designed as an inverted frustum.

[0019] The above technical solution uses the inner wall of the inverted round bottom to automatically gather the tea leaves after fixation towards the discharge port, facilitating the complete discharge of the tea leaves.

[0020] The beneficial effects of this utility model are as follows:

[0021] By setting up a frame, shaft, and electric telescopic rod, the fixing tank can be made to swing in a fan shape. With the help of a stirring fan driven by a drive motor, the tea leaves can be stirred evenly, avoiding the situation where some tea leaves are over-fixed and others are under-fixed due to uneven stirring during the fixing process. The controller can accurately control the fixing temperature, and with the help of a temperature sensor to monitor the internal temperature in real time, the heating effect can be effectively guaranteed.

[0035] The working principle of this utility model is as follows: When using this device to fix green tea, firstly, the power is turned on and the heating ring tube 6 is started through the controller 14 to raise the internal temperature of the fixing tank 2. The internal temperature change is monitored in real time through the temperature sensor 8. When the temperature reaches the preset temperature, the green tea is put into the fixing tank 2 through the feed port 7. At this time, the drive motor 3 is started to make the rotating shaft 4 and the stirring fan 5 rotate to stir the green tea. At the same time, the electric telescopic rod 16 is started to extend and retract continuously, causing the fixing tank 2 to swing continuously in a fan shape around the shaft 13, which helps the green tea inside to turn over and make the stirring and heating of the green tea more uniform. During the stirring process, impurities pass through the filter screen 10 and are discharged from the discharge pipe 11. After the green tea fixing is completed, the filter plate 9 can be pulled out. At this time, the processed green tea is discharged from the fixing tank 2 through the discharge pipe 11.
