Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing, and particularly relates to a withering device for tea processing. Background Art

[0002] Tea is a plant product made from the leaves of tea trees and is used for making tea by brewing after picking and processing. In the process of tea processing, withering is a very crucial step.

[0003] In traditional withering devices for tea processing, tea is usually placed in a steamer rack, and then manually turned regularly based on experience to ensure the quality of the tea. Although withering of the tea can be achieved, there are still some problems in use. The air circulation inside the tea layer is poor, and the contact between the tea and the air is not uniform enough, resulting in a less-than-ideal withering effect and a high dependence on manual operation. Content of the Utility Model

[0004] In view of this, the utility model provides a withering device for tea processing, which can coordinate and cooperate through a withering mechanism, a driving component, and a driving module. It not only promotes the air circulation inside the tea layer but also enables the tea to be turned on the tray, ensuring that the tea can uniformly contact the air, achieving a more ideal withering effect, and reducing the dependence on manual operation.

[0005] To solve the above technical problems, the utility model provides a withering device for tea processing, including a withering box and a withering mechanism arranged inside the withering box. The withering mechanism includes guide rails vertically and uniformly arranged on the left and right wall surfaces of the withering box respectively. A breathable sliding plate is longitudinally slidably connected between two horizontally adjacent guide rails. Slide bars are vertically slidably connected in the slide holes symmetrically arranged at the four corners of the breathable sliding plate. Breathable trays are arranged at the upper ends between multiple slide bars on the same breathable sliding plate. A driving component for driving the movement of the breathable tray is also arranged in the middle of the rear surface of the withering box, and a gas circulation component is also arranged on the withering box.

[0006] The withering mechanism further includes springs symmetrically arranged at the four corners between the upper surface of the breathable sliding plate and the lower surface of the vertically adjacent breathable tray respectively. The springs are respectively movably sleeved outside the same-side adjacent slide bars.

[0007] The driving component includes a mounting frame vertically and evenly arranged in the middle of the rear surface of the withering box. A rotating shaft is rotatably connected between the rotating holes longitudinally and symmetrically arranged in the middle of the front and rear wall surfaces of the mounting frame. Cams are provided at the front ends of the outer arcs of the rotating shafts. The rotating shafts are respectively arranged in cooperation with the vertically adjacent air-permeable trays. A driving module for driving the rotation of the rotating shafts is further provided at the rear end between the upper and lower wall surfaces of the withering box; the driving module includes round holes vertically and symmetrically arranged at the rear ends of the upper and lower wall surfaces of the withering box. A rotating shaft is rotatably connected between the two round holes. Vertically evenly distributed bevel gear rings are provided on the outer arc surface of the rotating shaft. Bevel gears are provided at the rear ends of the rotating shafts. The bevel gears are respectively meshed and connected with the adjacent bevel gear rings on the same side; the driving module further includes a motor arranged in the middle of the rear end of the upper surface of the withering box. The lower end of the output shaft of the motor is fixedly connected to the upper end of the rotating shaft. The motor is electrically connected to an external single-chip microcomputer.

[0008] The gas circulation component includes air inlets horizontally and symmetrically arranged at the lower ends of the left and right surfaces of the withering box. Air inlet covers are provided on the left and right surfaces of the withering box near the air inlets. The air inlet covers are respectively communicated with the adjacent air inlets on the same side. Horizontally symmetrically distributed air outlets are provided at the upper ends of the left and right surfaces of the withering box.

[0009] Pulling plates are provided in the middle of the front ends of the lower surfaces of the air-permeable sliding plates.

[0010] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0011] 1. Relevant staff regulate the operation of the motor through an external single-chip microcomputer. The rotation of the output shaft of the motor drives the synchronous rotation of the rotating shaft. When the rotating shaft rotates, through the meshing transmission of the bevel gears and bevel gear rings, the rotating shafts and the cams at their front ends rotate. As the cams rotate, the cams will push the cooperating air-permeable trays to perform up-and-down periodic movements. When the eccentric ends of the cams contact the air-permeable trays, the air-permeable trays and the sliding rods move upward against the elastic force of the springs. When the eccentric ends of the cams separate from the air-permeable trays, the air-permeable trays and the sliding rods move downward under the action of the elastic force of the springs. The above actions are repeated in this way, so that the air-permeable trays vibrate up and down. This action not only promotes the air circulation in the tea layer, but also makes the tea leaves turn over on the trays, ensuring that all the tea leaves can evenly contact the air, achieving a more ideal withering effect and reducing the dependence on manual operation.

[0012] 2. Relevant staff members place the tea leaves in the breathable trays in sequence. The design of the breathable trays and the breathable sliding plates allows air circulation, which helps the uniform evaporation of the moisture in the tea leaves, ensuring the aroma and taste of the tea. Then, the air inlet hoods are respectively connected to the exhaust pipes of the external air supply machines, and the external single-chip microcomputer controls the operation of the external air supply machines, so as to pump the gas with the set temperature and humidity into the withering box. After the gas enters the withering box, it flows upward, passes through the breathable sliding plates, the breathable trays and the tea leaf layer, and then is discharged from the air outlet at the upper part of the withering box, forming a natural circulation system, which helps to maintain a suitable temperature and humidity environment in the withering box, accelerates the withering process, and ensures the tea quality at the same time.

The springs 204 are respectively sleeved on the outside of the slide bars 202 adjacent to the same side.

[0021] As Figures 1-4 shown, the driving component includes mounting frames 300 vertically and evenly arranged in the middle of the rear surface of the withering box 100. Rotating shafts 301 are rotatably connected between the rotation holes longitudinally symmetrically arranged in the middle of the front and rear wall surfaces of the mounting frames 300. Cam 302 is provided at the front end of the outer arc surface of the rotating shaft 301. The rotating shafts 301 are respectively arranged in cooperation with the vertically adjacent air-permeable trays 203. A driving module for driving the rotation of the rotating shaft 301 is also provided at the rear end between the upper and lower wall surfaces of the withering box 100; the driving module includes circular holes vertically symmetrically arranged at the rear ends of the upper and lower wall surfaces of the withering box 100. A rotating shaft 400 is rotatably connected between the two circular holes. A conical tooth ring 401 with vertically evenly distributed is provided on the outer arc surface of the rotating shaft 400. Conical gears 402 are provided at the rear ends of the rotating shafts 301. The conical gears 402 are respectively meshed with the conical tooth rings 401 adjacent to the same side; the driving module further includes a motor 403 arranged in the middle of the rear end of the upper surface of the withering box 100. The lower end of the output shaft of the motor 403 is fixedly connected to the upper end of the rotating shaft 400. The motor 403 is electrically connected to an external single-chip microcomputer.

[0022] As Figures 1-3 shown, the gas circulation component includes air inlets 500 horizontally and symmetrically arranged at the lower ends of the left and right surfaces of the withering box 100. Air inlet covers 501 are provided on the left and right surfaces of the withering box 100 near the air inlets 500. The air inlet covers 501 are respectively communicated with the air inlets 500 adjacent to the same side. Air outlets 502 with horizontally symmetric distribution are provided at the upper ends of the left and right surfaces of the withering box 100.

[0023] The working principle of a withering device for tea processing provided by the present utility model is as follows: First, relevant staff place tea leaves in the breathable tray 203 in sequence. The design of the breathable tray 203 and the breathable slide plate 201 allows air circulation, which helps the uniform evaporation of the moisture in the tea leaves, ensuring the aroma and taste of the tea. Then, the air inlet hood 501 is respectively connected to the exhaust pipes of external air supply machines, and then the external single-chip microcomputer controls the operation of the external air supply machines, so as to pump gas with a set temperature and humidity into the withering box 100. After the gas enters the withering box 100, it flows upward, passes through the breathable slide plate 201, the breathable tray 203 and the tea leaf layer, and then is discharged from the air outlet 502 at the upper part of the withering box, forming a natural circulation system, which helps to maintain a suitable temperature and humidity environment in the withering box 100, accelerate the withering process, and ensure the tea quality at the same time. During this process, relevant staff control the operation of the motor 403 through the external single-chip microcomputer. The output shaft of the motor 403 rotates to drive the rotating shaft 400 to rotate synchronously. When the rotating shaft 400 rotates, it drives the rotating shaft 301 and the cam 302 at its front end to rotate through the meshing transmission of the bevel gear 402 and the bevel gear ring 401. As the cam 302 rotates, the cam 302 will push the cooperating breathable tray 203 to perform periodic up and down movements. When the eccentric end of the cam 302 contacts the breathable tray 203, the breathable tray 203 and the slide rod 202 move upward against the elastic force of the spring 204. When the eccentric end of the cam 302 separates from the breathable tray 203, the breathable tray 203 and the slide rod 202 move downward under the action of the restoring force of the spring 204. The above actions are repeated in this way, so that the breathable tray 203 vibrates up and down. This action not only promotes the air circulation in the tea leaf layer, but also makes the tea leaves turn over on the tray, ensuring that all the tea leaves can evenly contact the air, achieving a more ideal withering effect and reducing the dependence on manual operation.

[0024] As Figures 2-3 shown, pull plates 600 are provided in the middle of the front end of the lower surface of the breathable slide plate 201, which facilitates the staff to quickly pull out the breathable slide plate 201.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
