Description

Technical Field

[0001] This utility model relates to the technical field of tea production equipment, and in particular to a dandelion black tea withering device. Background Technology

[0002] Dandelion, also known as mother-in-law's nail, yellow flower ground nail, and yellow flower seedling, is a perennial herb. Dandelion is both a food and a medicine, and its medicinal, edible, nutritional, and cosmetic value has been highly praised and affirmed in the *Compendium of Materia Medica*, the *Cihai* dictionary, and other ancient medical encyclopedias. Dandelion contains nutrients such as taraxerol, choline, organic acids, inulin, glucose, carotene, fat, protein, vitamins, trace elements, and cellulose. Modern medical research has shown that it possesses triple antiviral, anti-infective, and anti-tumor effects, attracting international attention.

[0003] If dandelion is made into a steeped black tea, its nutrients can be utilized more conveniently and effectively, resulting in excellent health benefits. The production of dandelion black tea requires a withering process. The main purpose of withering is to reduce the water content of the fresh leaves and stems, promoting complex chemical changes caused by enzymes. Traditional withering methods (especially those used in small-scale home workshops) involve spreading freshly picked tea leaves into a certain thickness for sun drying. However, this method is inefficient, has a long withering cycle, and affects the continuous production of tea. Utility Model Content

[0004] To address the above situation and overcome the shortcomings of existing technology, this utility model provides a dandelion black tea withering device. The technical solution it provides includes a housing, characterized in that the housing is a closed cuboid shape, with several evenly distributed ventilation holes at the upper end of the housing. A baffle is integrally arranged at the upper end of the housing, and a chain conveyor belt corresponding to the ventilation holes is installed on the inner wall of the baffle. An air outlet is provided at the left end of the housing, and an installation cylinder coaxially arranged with the air outlet is detachably connected to the left end of the housing. A sealing plate is integrally arranged at the left end of the installation cylinder, and several ventilation slots are evenly distributed around the sealing plate. A first fan coaxially arranged with the sealing plate is installed at the right end of the sealing plate. A bracket is coaxially fixedly connected to the right end of the installation cylinder, and multiple connecting frames are integrally arranged around its axis on the bracket. Each connecting frame is fitted with an obliquely arranged heating plate. An installation plate is fixedly connected to the inner wall of the housing, and a second fan coaxially arranged with the air outlet is installed on the installation plate.

[0005] Preferably, a connecting flange is integrally and coaxially arranged on the right end of the mounting cylinder, and a connecting hole for use with the connecting flange is opened on the left end of the housing, and the connecting hole is fitted with bolts for fixing the connecting flange.

[0006] The beneficial effects of this utility model are:

[0007] 1. In use, this application features a chain conveyor belt arranged above the machine casing via a barrier to facilitate the spreading of dandelion black tea awaiting withering. A first fan is located at the left end of the machine casing via an installation cylinder and a sealing plate. Several electric heating plates are arranged at the right end of the installation cylinder via connecting frames on a support frame. During withering, the electric heating plates are first activated to generate high heat, followed by the activation of the first fan. The fan propels air to the right, where it interacts with the high-heat electric heating plates and is heated. The heated air continues to flow to the right into the casing, filling it with heated air. This heated air rises through vents to further heat the dandelion black tea on the chain conveyor belt, thereby improving withering efficiency. After withering, the chain conveyor belt is activated, moving the withered tea leaves to the right to facilitate the operator's transfer of the tea leaves at the right end of the chain conveyor belt.

[0008] 2. Furthermore, the electric heating plate provided in this application is arranged at an angle, which greatly increases the contact area and time between it and the air blown by the first fan, thereby ensuring the heating effect on the air. In addition, the electric heating plate is evenly distributed around the support, forming a structure similar to a guide plate, which facilitates the even distribution of air.

[0016] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0017] In the first embodiment, the technical solution is as follows: During use, a chain conveyor belt 4 is arranged above the casing 1 via a barrier 3 to facilitate the spreading of dandelion black tea to be withered. A first fan 9 is arranged at the left end of the casing 1 via an installation cylinder 6 and a sealing plate 7. Several electric heating plates 12 are arranged at the right end of the installation cylinder 6 via a connecting frame 11 on a bracket 10. During the withering process, the electric heating plates 12 are first activated to generate high heat, and then the first fan 9 is activated. The first fan 9 blows air to the right. During the rightward flow of the air, it interacts with the high-heat electric heating plates 12 and is heated. The heated air continues to flow to the right and enters the casing, filling the casing with heated air. The heated air rises through the vent 2 to heat the dandelion black tea on the chain conveyor belt 4, thereby improving the withering efficiency. After withering is completed, start the chain conveyor belt 4. The chain conveyor belt 4 can move the withered tea leaves to the right so that the operator can transfer the tea leaves at the right end of the chain conveyor belt 4.

[0018] Furthermore, the heating plate 12 provided in this application is arranged at an angle, which greatly increases its contact area and time with the air blown by the first fan 9, thereby ensuring the heating effect on the air. In addition, the heating plate 12 is evenly distributed around the support 10, forming a structure similar to a baffle, which facilitates the even distribution of air. A second fan 14 is arranged on the mounting plate 13 to blow the heated air to fill the casing 1.

[0019] In Example 2, based on Example 1, specifically, in this application, the dandelion black tea to be withered is first evenly spread on the chain conveyor belt 4 with a suitable thickness. The chain conveyor belt 4 has a certain gap and air permeability, and as a metal structure, it has good heat transfer properties. These properties facilitate the action of hot air in the housing 1 on the dandelion black tea on the chain conveyor belt 4. Then, the electric heating plate 12 is activated to generate high heat, followed by the activation of the first fan 9 on the sealing plate 7. The sealing plate 7 is provided with ventilation slots 8 to allow the first fan 9, which is in operation, to blow external air towards the air outlet 5. Under the action of the first fan 9, air enters the housing 1 from left to right through the bracket 10 and the air outlet 5. When the air passes through the bracket 10, it comes into contact with the electric heating plate 12 on the connecting frame 11. The high-heat electric heating plate 12 raises the temperature of the air, which then flows into the housing 1 through the air outlet 5. Furthermore, the electric heating plate 12 is arranged at an angle, which greatly increases the contact area and time between it and the air blown by the first fan 9, thereby ensuring the heating effect of the air. In addition, the electric heating plate 12 is evenly distributed around the support 10, forming a structure similar to a guide plate, which facilitates the even distribution of air. After that, the heated air will enter the casing 1 under the action of the second fan 14, so that the air heated by the electric heating plate 12 can fill the casing. Since the casing is closed, the heated gas can only overflow upward through the vent 2. The overflowing gas will act on the dandelion black tea on the chain conveyor belt 4, thereby improving its withering efficiency.

[0020] In Example 3, based on Example 2, a connecting flange 15 is arranged on the mounting cylinder 6. The connecting flange 15 is fastened to the left end of the housing 1 through the connecting hole 16 and bolts 17. This connection method facilitates the disassembly of the mounting cylinder 6 and the maintenance of the corresponding parts.
