Description

Technical Field

[0001] The utility model relates to the technical field of tea production, and more specifically, to a tea withering device for tea production. Background Art

[0002] Tea withering refers to the heat treatment of picked tea leaves to stop the enzyme activity in the tea leaves and prevent the fermentation and oxidation reactions of the tea leaves, thereby maintaining the color, aroma and nutrients of the tea leaves.

[0003] Due to the different enzyme activities of different teas, the methods and temperatures for withering different types of tea are different. For example, oolong tea and black tea are made by frying. In the prior art, a drum-type withering machine is used to wither the tea leaves, which has the effects of uniform heating and high yield. The specific operation is to put the picked oolong tea and black tea leaves into a drum, and under the high temperature heating of an external heating device, the drum rotates and stir-fries quickly.

[0004] However, for tea leaves with large differences in thickness, the degree of heating they receive in the drum will vary. Specifically, tea leaves with thinner leaves are more easily heated than tea leaves with thicker leaves. That is, at the same temperature, the withering time of thick tea leaves is longer than that of thin tea leaves. Therefore, the withering time and temperature need to be controlled and adjusted in real time, which is a more cumbersome operation. Utility Model Content

[0009] In a preferred embodiment, the box body is communicated with the heating box, a heating mechanism is fixedly installed inside the heating box, and the heating mechanism is located directly below the barrel assembly.

[0010] In a preferred embodiment, the blocking mechanism includes a movable seat, one end of which is fixedly provided with a partition plate, and the cross section of the partition plate is arc-shaped.

[0011] In a preferred embodiment, an exhaust port is provided at one end of the movable seat close to the partition plate, a waste box is provided on the outside of the heating box, and the waste box is fixedly installed on the support frame.

[0028] It should be noted that the outer cylinder 311 is a cylindrical component with a closed outer circumference, the middle cylinder 312 and the inner cylinder 313 are both mesh components, the mesh size of the middle cylinder 312 and the inner cylinder 313 is the same, and tea leaves of different thicknesses are placed inside the outer cylinder 311, the middle cylinder 312 and the inner cylinder 313. The thickness of the tea leaves inside the outer cylinder 311 is greater than the thickness of the tea leaves inside the middle cylinder 312, and the thickness of the tea leaves inside the middle cylinder 312 is greater than the thickness of the tea leaves inside the inner cylinder 313.

[0029] Furthermore, a feeding hopper 4 is installed on the support frame 1, and the feeding hopper 4 is located outside one end of the barrel assembly 3 close to the fixed plate 32, and a feeding port 324 is provided between the outer fixed ring 321 and the middle fixed ring 322 and between the middle fixed ring 322 and the inner fixed ring 323, and a connecting plate 325 is fixed inside the feeding port 324, and the connecting plate 325 is arranged in an arc shape.

[0030] It should be noted that the hopper 4 is tilted, and the bottom of the hopper 4 is connected to the box body 2 through a rotating shaft, that is, the hopper 4 can adjust the tilt angle, and the lower end of the hopper 4 corresponds to the feeding port 324, and the outer fixing ring 321, the middle fixing ring 322 and the inner fixing ring 323 are connected as a whole through the connecting plate 325.

[0031] Furthermore, a driving box 33 is provided at one end of the net cylinder 31, and the driving box 33 is fixedly installed inside the box body 2. The bottoms of both ends of the net cylinder 31 are rotatably connected with driving wheels 331, and the driving wheels 331 are rotatably arranged on the inner wall of the box body 2. A servo motor is installed inside the driving box 33, and one group of driving wheels 331 is fixedly connected to the output end of the servo motor.

[0032] It should be noted that wheel grooves are provided at both ends of the barrel assembly 3 , and the driving wheel 331 is matched with the wheel grooves to support the barrel assembly 3 to rotate.

[0033] Furthermore, the box body 2 is communicated with the heating box 5 , a heating mechanism is fixedly installed inside the heating box 5 , and the heating mechanism is located directly below the barrel assembly 3 .

[0034] It should be noted that the heating mechanism is an electric heating tube or an electric heating plate, which is used to wither the tea leaves inside the mesh cylinder 31 .

[0035] In this embodiment, the implementation scenario is specifically as follows: first, the heating mechanism inside the heating box 5 is turned on, and then tea leaves of different thicknesses are respectively sent into the outer cylinder 311, the middle cylinder 312 and the inner cylinder 313 through the feeding hopper 4, and finally the servo motor inside the driving box 33 is turned on, thereby driving the barrel assembly 3 to rotate, and the tea leaves inside the outer cylinder 311, the middle cylinder 312 and the inner cylinder 313 are withered. Since the withering temperature of thick tea leaves is higher than that of thin tea leaves, the mesh cylinder 31 is divided into multiple layers, and thin tea leaves are placed in the inner layer close to the center, and tea leaves of increasing thickness are placed from the inner layer to the outer layer. This arrangement makes the thick tea leaves closer to the heating mechanism than the thin tea leaves, and the heating speed of the outer layer is faster than that of the inner layer, which can shorten the withering time of the thick tea leaves. Therefore, when the withering time remains unchanged, it is easier to control the withering temperature, and there is no need to adjust the withering temperature multiple times according to the withering time, and the operation is simpler.

[0036] In the above embodiment, tea leaves will produce tea stems and broken leaves when they are stir-fried. The tea stems and broken leaves in the inner layer will be thrown to the outer layer during stir-frying. Because of their small size, they are easily "burned" after being stir-fried at high temperature in the outer layer. The tea stems and broken leaves in multiple layers gather in the outer layer. When there are too many of them, the burnt smell will affect the taste of the thick tea leaves in the outer layer. In order to solve this problem, the following technical solutions are provided:

[0037] Refer to the instruction manual Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 A blocking mechanism is provided between the outer cylinder 311 and the middle cylinder 312, and the blocking mechanism is used to prevent the tea leaves inside the middle cylinder 312 from entering the outer cylinder 311. The blocking mechanism includes a movable seat 35, and a partition plate 36 is fixedly provided at one end of the movable seat 35, and the cross-section of the partition plate 36 is an arc-shaped setting.

[0038] It should be noted that the length of the partition plate 36 is slightly smaller than the length of the net cylinder 31 , and the movable seat 35 is movably disposed at one end of the net cylinder 31 away from the fixed plate 32 .

[0039] Furthermore, an exhaust port 351 is provided at one end of the movable seat 35 close to the partition plate 36, a waste box 6 is provided on the outside of the heating box 5, and the waste box 6 is fixedly installed on the support frame 1. The waste box 6 and the movable seat 35 are connected by a pipeline, and an exhaust pump is fixedly installed inside the waste box 6, and a filter is provided above the exhaust pump.

[0040] It should be noted that the bottom of the box body 2 is provided with a discharge port, which is located between the heating box 5 and the waste box 6 , and the air exhaust port 351 is directly opposite to the arc top of the partition plate 36 .

[0041] Furthermore, a driving motor 34 is provided on the outside of the driving box 33 , and the driving motor 34 is fixedly installed inside the supporting frame 1 , an extension column 37 is fixedly provided on the top of the movable seat 35 , and the output end of the driving motor 34 is fixedly connected to the extension column 37 .

[0042] It should be noted that the extension column 37 is located at one end of the middle cylinder 312 , and the connection point between the output end of the drive motor 34 and the extension column 37 is located on the central axis of the inner cylinder 313 .

[0043] Furthermore, a pad 352 is fixedly provided at one end of the movable seat 35 close to the partition plate 36, the pad 352 and the partition plate 36 are connected, a ventilation column 361 is fixedly provided on the inner wall of the partition plate 36, and an air pump 2 is fixedly installed at the bottom of the pad 352, and the exhaust end of the air pump 2 is connected to the pad 352.

[0044] It should be noted that the interiors of the pad 352 and the partition plate 36 are both hollow, the cross-section of the ventilation column 361 is semicircular, and the arc surface of the ventilation column 361 is set upward to prevent the ventilation column 361 from blocking the tea stems and broken leaves from sliding down along the inner wall of the partition plate 36.

[0045] In this embodiment, the implementation scenario is specifically as follows: when starting the machine, first start the drive motor 34 to drive the movable seat 35 and the partition plate 36 to rotate through the extension column 37, rotate the partition plate 36 to the top of the middle cylinder 312, and then start the heating mechanism inside the heating box 5 to preheat the net cylinder 31. After the temperatures inside the outer cylinder 311, the middle cylinder 312 and the inner cylinder 313 reach the requirements, rotate the partition plate 36 to the bottom of the middle cylinder 312, and then send the tea leaves into the outer cylinder 311, the middle cylinder 312 and the inner cylinder 313, rotate the net cylinder 31 to stir-fry and kill the tea leaves, and the net design facilitates the hot air to circulate between the middle cylinder 312 and the inner cylinder 313, and pass through the bottom of the pad 352 The second vacuum pump draws the hot air inside the outer cylinder 311 into the pad 352, and then into the partition plate 36 and is discharged through the ventilation column 361, thereby solving the problem of the partition plate 36 blocking the circulation of hot air, and the tea stems and broken leaves fall to the outer cylinder 311 at the bottom along the mesh, and are blocked by the partition plate 36 so that the tea stems and broken leaves fall on the partition plate 36, and the vacuum pump 1 inside the waste box 6 is turned on, and the tea stems and broken leaves on the partition plate 36 are extracted through the vacuum port 351, and finally the tea stems and broken leaves are pumped onto the filter screen inside the waste box 6, which effectively solves the problem of the tea stems and broken leaves in the inner layer gathering to the outer layer, and avoids the excessive number of tea stems and broken leaves in the outer layer affecting the taste of the thick tea leaves in the outer layer.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
