[0002] A fixation machine is a mechanical device used in tea processing. Its main purpose is to destroy and deactivate the oxidase activity in fresh leaves through high temperatures, inhibiting the enzymatic oxidation of tea polyphenols and other substances in the leaves, and preventing discoloration during the drying process. At the same time, the fixation machine can also remove the grassy odor and promote the formation of a pleasant aroma.

[0003] Chinese utility model patent application number 202322049023.9 ​​provides a tea drum fixing machine for uniform drying. Tea leaves are put into the drum through the feed inlet, the tea leaves are stirred by the stirring device, the drum is heated by the heating device, and the tea leaves inside the drum are dried by the drying device, so that the tea leaves can be fully heated and the quality of the tea leaves can be improved.

[0004] However, during the use of the above equipment, it was found that the equipment mainly uses resistance wire heating. However, this heating method is prone to causing local overheating, and there is a large temperature difference between the area around the resistance wire and the area away from the resistance wire. At the same time, the equipment relies on stirring plate and scraper for stirring, which can easily create dead corners in the stirring, resulting in some tea leaves not being able to be fully turned over, and thus making it difficult for some tea leaves to be effectively de-enzymed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a temperature distribution device for a drum-type fixation machine for tea processing. This solves the problem mentioned in the background technology, which uses resistance wire heating. However, this heating method easily leads to excessively high local temperatures, and there is a large temperature difference between the area around the resistance wire and the area away from the resistance wire. In cases where some tea leaves cannot be fully turned over, it is difficult to effectively fix the tea leaves.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature distribution device for a drum-type tea processing fixing machine, comprising a support and an outer cylinder. A drum is rotatably mounted inside the outer cylinder. An exhaust groove is provided at the top of the outer cylinder, and the top of the exhaust groove is connected to an exhaust box via an exhaust pipe. An air jet pipe is fixedly provided at the bottom of the outer cylinder, and the air jet pipe is connected to a hot air blower via a telescopic hose. The hot air blower is mounted on a base plate at the bottom of the support. A drive assembly is connected to the rear end of the drum. Ventilation holes are arranged in a ring array on the drum, and baffles are arranged in a ring array on the inner wall of the drum.

[0007] Preferably, a dehumidifying plate is installed in the inner cavity of the exhaust box.

[0008] Preferably, the drive assembly includes a mounting bracket, which is fixedly mounted on one end of the outer cylinder.

[0011] Preferably, a hydraulic rod is rotatably mounted on the base plate at the rear end of the bracket, and the output end of the hydraulic rod is rotatably connected to the outer cylinder.

[0012] This utility model provides a temperature distribution device for a drum-type fixation machine used in tea processing. It has the following beneficial effects:

[0013] (1) This utility model uses a hot air blower and a jet pipe to evenly introduce hot air into the drum through the air vent and circulate it inside the outer drum, making the overall temperature inside the drum more uniform. At the same time, the continuous rotation of the drum and the use of the paddle plate to turn the tea leaves as the drum rotates can reduce the dead corners of stirring and ensure that each tea leaf can fully contact the hot air to achieve uniform fixation.

[0014] (2) This utility model uses a hydraulic rod to control the tilt angle of the outer cylinder by extending and retracting the hydraulic rod, which facilitates the smooth discharge of tea leaves from the drum after the tea leaves have been processed. This allows for rapid discharge without much manual intervention, thus improving production efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example 1:

[0022] Please see Figures 1-4 This utility model provides a temperature distribution device for a drum-type tea processing fixation machine, including a support 1 and an outer cylinder 2. A drum 4 is rotatably installed inside the outer cylinder 2. An exhaust groove 23 is provided at the top of the outer cylinder 2. The top of the exhaust groove 23 is connected to an exhaust box 3 through an exhaust pipe. An air jet pipe 24 is fixedly provided at the bottom of the outer cylinder 2. The air jet pipe 24 is connected to a hot air blower 5 through a telescopic hose 21. The hot air blower 5 is installed on the bottom plate of the support 1. A drive assembly 6 is connected to the rear end of the drum 4. Ventilation holes 41 are arranged in an annular array on the drum 4. A baffle plate 42 is arranged in an annular array on the inner wall of the drum 4.

[0023] A dehumidifying plate 31 is installed in the inner cavity of the exhaust box 3;

[0024] The drive assembly 6 includes a mounting bracket 64, which is fixedly mounted on one end of the outer cylinder 2. A motor 61 is fixedly mounted on the mounting bracket 64. The output end of the motor 61 is connected to a first gear 62, which meshes with a second gear 63. The second gear 63 is fixedly connected to the rear end of the roller 4.

[0025] The number of teeth on the first gear 62 is less than the number of teeth on the second gear 63.

[0026] Specifically, the tea leaves to be processed are placed into the drum 4, and the hot air blower 5 is turned on. The hot air generated by the hot air blower 5 enters the jet pipe 24 through the telescopic hose 21, and then the hot air is sprayed into the space between the outer cylinder 2 and the drum 4 through the jet pipe 24. The hot air enters the inside of the drum 4 through the vent hole 41 on the drum 4 to heat and process the tea leaves. At the same time, it can make the heat more evenly distributed in the drum 4, avoid the problem of excessive local temperature, ensure that the tea leaves are processed at a consistent temperature, and improve the quality of the tea leaves.

[0027] When the motor 61 starts, the first gear 62 at its output end rotates, and the second gear 63 meshing with the first gear 62 rotates accordingly, thereby driving the drum 4 to rotate. The paddle plate 42 on the inner wall of the drum 4 turns the tea leaves as the drum 4 rotates, so that the tea leaves move continuously in the drum 4, fully contact the hot air, achieve uniform fixation, and prevent the tea leaves from piling up in a certain position, which would cause uneven heating.

[0028] The hot air and water vapor generated during the blanching process enter the exhaust box 3 through the exhaust groove 23 at the top of the outer cylinder 2 and the exhaust pipe. The dehumidification plate 31 in the exhaust box 3 can remove water vapor and purify the exhaust gas. The dehumidification plate 31 can be easily removed for cleaning or replacement. Removing water vapor can prevent water vapor from spreading in the workshop, avoid excessive humidity in the surrounding environment, and ensure the comfort of the working environment.

[0029] Furthermore, for rapid material discharge, please refer to [link / reference needed]. Figures 1-4 A bracket 11 is fixedly installed on the rear end of the bracket 1. The bracket 11 fits against the surface of the outer cylinder 2. A rotating frame 12 is provided on the front end of the bracket 1. The rotating frame 12 is hinged to the rotating plate 22. The rotating plate 22 is fixedly installed at the bottom of the front end of the outer cylinder 2.

[0030] A hydraulic rod 13 is rotatably mounted on the base plate at the rear end of the support 1, and the output end of the hydraulic rod 13 is rotatably connected to the outer cylinder 2.

[0031] Specifically, after the tea leaves are processed, the hydraulic rod 13 is activated. The output end of the hydraulic rod 13 pushes the outer cylinder 2. Since the front end of the outer cylinder 2 is hinged to the rotating frame 12 through the rotating plate 22 and the rear end is supported by the bracket 11, under the action of the hydraulic rod 13, the outer cylinder 2 rotates upward at a certain angle about the hinge point between the rotating frame 12 and the rotating plate 22. At this time, the drum 4 also tilts accordingly, and the tea leaves are quickly discharged from the drum 4 under the action of gravity.

[0032] The outer cylinder 2 and the drum 4 are tilted by the hydraulic rod 13, and the tea leaves are quickly discharged by gravity. Compared with manual discharge or other slower discharge methods, the discharge time is greatly shortened and the production efficiency is improved. The equipment can enter the next round of withering operation more quickly. At the same time, the tilt angle of the drum 4 can be precisely controlled by the hydraulic rod 13, so that all the tea leaves can be discharged as much as possible, reducing the amount of tea leaves left in the drum 4 and preventing the residual tea leaves from affecting the quality of the next batch of tea leaves due to excessive heating or deterioration.

[0033] Working principle: The tea leaves to be processed are placed inside the drum 4. The hot air blower 5 is started, and the hot air generated by the hot air blower 5 enters the jet pipe 24 through the telescopic hose 21. Then, the hot air is sprayed into the space between the outer cylinder 2 and the drum 4 through the jet pipe 24. The hot air enters the inside of the drum 4 through the vent hole 41 on the drum 4 to heat and process the tea leaves. At the same time, the motor 61 is started. The first gear 62 at the output end of the motor 61 rotates, driving the second gear 63 that meshes with it to rotate, thereby rotating the drum 4. The baffle plate 42 on the inner wall of the drum 4 turns the tea leaves, so that the tea leaves can fully contact the hot air and achieve uniform processing.

[0034] After the tea leaves have finished processing, the hydraulic rod 13 is activated. The output end of the hydraulic rod 13 pushes the outer cylinder 2, which rotates upward at a certain angle around the hinge point between the rotating frame 12 and the rotating plate 22. The drum 4 also tilts accordingly, and the tea leaves are quickly discharged from the drum 4 under the action of gravity. After the discharge is completed, the equipment can be reset to prepare for the next round of tea leaf processing.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
