[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0018] Reference Figures 1-3As shown, a temperature-controlled shaking machine for the processing of Meiren tea includes a frame 1, a shaking barrel 2, a temperature control device 3, and a frequency conversion drive device 4. The shaking barrel 2 includes a stainless steel cylinder 21 and a bamboo strip cylinder 22, with the bamboo strip cylinder 22 disposed inside the stainless steel cylinder 21. The temperature control device 3 is disposed inside the stainless steel cylinder 21 to adjust the temperature inside the stainless steel cylinder 21 to simulate the natural day-night temperature difference, thereby accelerating the enzymatic oxidation reaction of fresh leaves. The temperature control device 3 can precisely control the temperature inside the stainless steel cylinder 21, reducing the influence of ambient temperature and humidity, thus stabilizing the quality of the tea. The frequency conversion drive device 4 is disposed on the frame 1 and is connected to the bamboo strip cylinder 22 to drive the bamboo strip cylinder 22 to rotate at a variable frequency to dynamically adjust the shaking force, avoiding excessive damage or insufficient fermentation of the tea caused by traditional fixed-speed shaking.
[0019] The stainless steel cylinder 21 is provided with a ventilation window 211 at its end, and the ventilation window 211 is composed of multiple small holes.
[0020] The temperature control device 3 includes a heating wire 31, a thermoelectric cooler 32, a temperature and humidity sensor 33, a blower 34, and a temperature controller 35. Multiple heating wires 31 and multiple thermoelectric coolers 32 are arranged at intervals on the inner wall of the stainless steel cylinder 21. Multiple temperature and humidity sensors 33 are installed inside the stainless steel cylinder 21 to monitor the temperature and humidity inside in real time. The blower 34 is mounted on the frame 1 and is connected to the stainless steel cylinder 21 to blow air into it. The temperature controller 35 is signal-connected to the heating wire 31, the thermoelectric cooler 32, the temperature and humidity sensor 33, and the blower 34 to control the heating of the heating wire 31, control the cooling of the thermoelectric cooler 32, receive temperature feedback from the temperature and humidity sensor 33, and control the blower 34 to blow air into the stainless steel cylinder 21. When cooling the stainless steel cylinder 21, the semiconductor cooling chip 32 cools the inside of the stainless steel cylinder 21 to reduce the temperature inside the stainless steel cylinder 21, and the blower 34 blows air into the stainless steel cylinder 21 to accelerate the dissipation of hot air from the ventilation window 211. At the same time, when not cooling, the blower 34 can also blow air into the stainless steel cylinder 21 to promote the oxidation of fresh leaves.
[0021] The variable frequency drive device 4 includes a motor frame 41, a variable frequency motor 42, and a drive controller 43. The motor frame 41 is mounted on the frame 1. The variable frequency motor 42 and the drive controller 43 are both mounted on the motor frame 41. The drive controller 43 is signal-connected to the variable frequency motor 42 to control the start, stop, and speed of the variable frequency motor 42. The variable frequency motor 42 is connected to the bamboo tube 22. The variable frequency motor 42 controls the shaking force by controlling the speed of the bamboo tube 22.
[0022] The stainless steel cylinder 21 has a first opening 212, and a rotatable first door leaf 5 is provided at the first opening 212; the bamboo tube 22 has a second opening 221, and a rotatable second door leaf 6 is provided at the second opening 221. The bamboo tube 22 has a first connecting seat, and the first connecting seat has a first through hole. The second door leaf 6 has a second connecting seat, and the second connecting seat has a second through hole. A pin is provided in the first through hole and the second through hole to connect and fix the first connecting seat and the second connecting seat.
[0023] The bamboo tube 22 has raised strips 222 inside, which are elongated and extend parallel to the axis of the bamboo tube 22. The raised strips 222 are made of silicone material. When the bamboo tube 22 rotates, the raised strips 222 tumble the tea leaves, promoting friction and activating polyphenol oxidase by disrupting the tea cell structure. This causes enzymatic oxidation and condensation of phenolic substances in the cells, producing brownish-red quinones, resulting in browning and reddening of the tea leaves.
[0024] The stainless steel cylinder 21 is equipped with a UV sterilization lamp 7, which can be used for sterilization during non-working periods.
[0025] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
