Description

Technical Field

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

[0002] The main purpose of fixing tea leaves 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 the fresh leaves, evaporate some of the moisture in the 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 a good aroma.

[0003] Currently, most common tea fixing devices use electric heating to perform pan-frying or drum-type fixing. However, a single heating method cannot be adjusted for different stages of tea processing, and it is difficult to improve the efficiency of fixing with a single heating method. Therefore, a tea fixing device is proposed. Utility Model Content

[0014] The technical solutions of the present 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 the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This utility model provides a technical solution: it includes a base 1, a wok 2 connected to the top of the base 1, a top cover 3 connected to the top of the wok 2, a thermostat connected to the surface of the top cover 3 for controlling the temperature of the equipment, a drive motor 4 connected to the top of the top cover 3, a connecting shaft 5 connected to the output end of the drive motor 4, the bottom end of the connecting shaft 5 extending into the wok 2 and connected to a kneading mechanism 6, a temperature sensor 7 and a humidity sensor 8 connected to the top of the kneading mechanism 6, a temperature sensor 10 connected to one side of the inner wall of the wok 2, and an ultrasonic generator 14 connected to the bottom end of the ultrasonic generator 14, which adopts a piezoelectric ceramic transducer, and an electric heating film 11 connected to one side of the inner cavity of the wok 2.

[0016] Reference Figure 2 As shown, a drain pipe 15 is connected to the bottom of the wok 2, and the wok 2 is filled with pure water. The drain pipe 15 is used to drain or replenish the pure water in the wok 2, and new water can also be injected into the wok 2 through the drain pipe 15. Inside the water cavity, the ultrasonic waves generated by the ultrasonic generator 14 produce a strong cavitation effect. The powerful shock waves and micro-jet generated when the cavitation bubbles collapse will propagate in the water and impact the wok 2 above which carries the tea leaves. This impact will produce high-frequency, microscopic, and intense vibrations, which will be directly transmitted to the tea leaves through the wok 2. This vibration is much stronger than the ultrasonic vibration in the air and can effectively destroy the cell structure of the tea leaves.

[0017] Reference Figure 1 As shown, a feed cover plate 16 is hinged to one side of the top cover 3, and a handle 161 is connected to one side of the feed cover plate 16. The feed cover plate 16 is opened by the handle 161, and the tea leaves to be processed are placed into the 2. The handle 161 is pressed against one side of the top cover 3 for positioning the feed cover plate 16.

[0018] Reference Figure 1 and Figure 2 As shown, an air outlet pipe 12 is connected to the top of the top cover 3, and a fan 13 is connected between the inner walls of the air outlet pipe 12. When the blanching work is carried out, the fan 13 can discharge the generated water vapor through the air outlet pipe 12.

[0019] Reference Figure 3 and Figure 4As shown, the frying and kneading mechanism 6 includes an octagonal frame 61. A controller 62 and multiple electric push rods 63 are connected to the bottom of the inner wall of the octagonal frame 61. Each electric push rod 63 has a traction frame 64 connected to its output end. One side of the traction frame 64 is slidably connected to the octagonal frame 61, while the other side, which is away from each other, is connected to a frying plate 65 and a mounting buckle 66. A tea-rubbing sheet 67, composed of sponge and cotton cloth, is connected to one side of the mounting buckle 66. The drive motor 4, when started, drives the octagonal frame 61 to rotate via the connecting shaft 5, thereby... The traction frame 64 drives the mounting buckle 66 and the frying plate 65 to rotate. When it is necessary to turn the tea leaves, the corresponding electric push rod 63 retracts, and the traction frame 64 drives the frying plate 65 to move down and fit against the inner wall of the frying pan 2. As the octagonal frame 61 rotates, the tea leaves are turned over and fried. After the frying is completed, the frying plate 65 is raised, and then another set of electric push rods 63 is activated to drive the mounting buckle 66 to move down, so that the tea-rubbing pieces 67 are close to the inner wall of the frying pan 2. The drive motor 4 is adjusted to forward and reverse rotation. As it rotates, the softened tea leaves are rubbed and the tea leaves are subjected to the fixation process.

[0020] Reference Figure 4 As shown in the figure, a through hole is provided on one side of the octagonal frame 61 corresponding to the traction frame 64. The top of the traction frame 64 located inside the octagonal frame 61 is connected to the same retaining ring 9. As can be seen from the attached figure, the traction frame 64 blocks the through hole located below, while the retaining ring 9 blocks the through hole located above, thus preventing tea leaves from entering the octagonal frame 61 during processing.

[0021] The implementation principle of this application is as follows: First, open the feed cover 16 and put the tea leaves to be processed into the wok 2, then close the cover, turn on the electric heating film 11 and the ultrasonic generator 14. The electric heating film 11 heats the inner wall of the wok 2, thereby conducting heat to the tea leaves. The ultrasonic waves generated by the ultrasonic generator 14 can further improve the tea processing effect. Turn on the drive motor 4, which drives the stir-frying and kneading mechanism 6 to rotate through the connecting shaft 5, stir-frying and kneading the tea leaves. Temperature sensor 2 10 is used to monitor the temperature of the inner wall of the wok 2 to assist in temperature control. Temperature sensor 1 7 and humidity sensor 8 can detect the temperature and humidity inside the wok 2. The electric push rod 63 in the stir-frying and kneading mechanism 6 is divided into two groups, which respectively control the corresponding multiple sets of mounting buckles 66 and stir-frying plates 65. At the same time, the controller 62 receives control commands to complete the fixation operation of the tea leaves. After the fixation is completed, open the feed cover 16 and take out the tea leaves.
