Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of scenting and drying equipment for gardenia tea, and in particular to a scenting and drying equipment for gardenia tea. Background Technology
[0002] Gardenia tea is a special type of flower tea made from gardenia flowers and green or white tea. Through a scenting process, the tea leaves absorb the fragrance of the flowers. During the scenting process, the porous structure of the tea leaves effectively absorbs the aromatic substances released by the gardenia flowers. At the same time, the temperature and humidity are controlled to reduce the moisture in the flowers, prevent the tea leaves from becoming damp and deteriorating, and remove the bitter components of the flowers themselves. This results in a unique flavor that blends the aroma of the tea with the fragrance of the flowers. After the scenting process is completed, the tea leaves need to be dried to stop fermentation, fix the aroma, inhibit the growth of microorganisms and extend the shelf life. It also facilitates the separation of flower residue, ensuring the purity and stability of the finished tea.
[0003] Continuous production of scented tea typically uses a chain belt dryer, which is a type of continuous drying equipment. Its core structure includes a chain belt conveyor system, a drying chamber, a hot air circulation system, and a collection device. During operation, the scented tea is first evenly spread on the moving chain belt through the feed end. The chain belt slowly conveys the material through the drying chamber. Inside the chamber, hot air generated by the heating system removes the moisture, thus achieving drying. The dried material is finally discharged from the discharge end.
[0004] In existing applications of chain belt dryers, although the feeding device achieves the initial flat spreading of sachet tea on the conveyor belt surface, the sachet tea material and the conveyor belt remain relatively stationary during the subsequent drying process. This static stacking method results in a lack of effective disturbance and turning within the material layer, making it difficult for hot airflow to penetrate the entire material layer evenly. As a result, the sachet tea at the top of the material layer is prone to over-drying due to direct exposure to hot air, while the sachet tea in the lower layer close to the conveyor belt is under-heated due to obstructed heat conduction and insufficient airflow exchange, resulting in a significantly lagging drying effect compared to the upper layer. This significant inconsistency in the drying effect between the upper and lower layers severely restricts the uniformity and stability of the overall drying quality of the sachet tea. Utility Model Content
[0005] The purpose of this invention is to solve the problem of inconsistent drying effects when using chain belt dryers in the prior art, and to propose a drying device for scenting gardenia tea.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A drying device for scenting gardenia tea includes a conveying assembly and a drying hood fixedly installed on the conveying assembly. It also includes a drying tube rotatably installed inside the drying hood, wherein baffles are arranged in a ring on the circumference of the drying tube, and exhaust holes are provided on the drying tube and installed between adjacent baffles. A drive fan is symmetrically installed inside the drying tube. Heating elements are symmetrically arranged on the drying hood, with the heating elements equidistantly distributed on the drying hood.
[0008] In order to heat the air entering from outside the equipment, preferably, the heating element includes an air inlet box fixedly installed on the drying hood, wherein an installation block is fixedly installed at the air outlet end of the air inlet box, a heating zone is formed between the air inlet box and the installation block, a heating wire is fixedly installed in the heating zone, and an air intake fan is fixedly installed in the heating zone, with the air outlet end of the air intake fan facing the heating wire.
[0009] To accelerate the discharge of hot air into the drying tube, the mounting block is further configured with a tapered channel, and the drying tube is rotatably mounted on the mounting block.
[0010] To improve the rigidity of the drying tube, preferably, the ratio of the area of the drying tube to the total area of the exhaust holes is 4:1.
[0011] To facilitate the rotation of the drying tube, preferably, the air inlet end of the driving fan faces the mounting block, and the air inlet end of the driving fan shaft is set to be conical.
[0012] To improve the drying effect, preferably, at least four sets of drying tubes are provided.
[0013] Compared with the prior art, this utility model provides a scenting and drying device for gardenia tea, which has the following beneficial effects:
[0014] 1. This scenting and drying equipment for gardenia tea utilizes a drying pipe, an exhaust vent, and a turntable. The drying pipe rotates during operation, causing the turntable to rotate as well. This turns the tea leaves on the conveyor components, ensuring thorough heat transfer and airflow exchange, and even heating. This avoids the problem of inconsistent drying results caused by prolonged static placement of the tea leaves on the conveyor components. Simultaneously, the exhaust vent rotates with the drying pipe and dries the tea leaves while the turntable turns them, further enhancing the drying effect and preventing inconsistent drying between the upper and lower layers of tea.
[0015] 2. This scenting and drying equipment for gardenia tea allows air to enter from both ends of the drying tube simultaneously, and drives the drying tube to rotate via a fan. This saves on equipment manufacturing costs, and the drying tube can be driven to work by the flow of hot air, making it convenient to use.
[0016] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model utilizes the combined use of drying pipe, exhaust hole and deflector plate to effectively turn the flower tea above the conveyor belt, avoiding the flower tea from remaining stationary with the conveyor components, which would cause the hot airflow to be unable to reach the material layer, thus leading to the problem of inconsistent drying effect between the upper and lower layers of flower tea.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] Example:
[0025] Reference Figures 1-4A drying device for scenting gardenia tea includes a conveyor assembly 1 and a drying hood 2 fixedly mounted on the conveyor assembly 1. The conveyor assembly 1 mainly consists of a chain conveyor belt, a drive motor, and a frame. The chain conveyor belt is connected to the drive motor via rotating rollers. In this application, the drive motor is a Siemens 1FT6 series servo motor. The device also includes a drying tube 3 rotatably mounted inside the drying hood 2. At least four sets of drying tubes 3 are provided; in this application, five sets are preferred. The equidistant arrangement of these five sets ensures uniform drying of the gardenia tea while avoiding excessive turning that could damage it. A ring of baffles 5 is arranged on the circumference of the drying tube 3. The length of the baffles 5 is the same as the width of the conveyor belt, and the end face of the baffles 5 contacts the chain conveyor belt. When the drying tube 3 rotates… The rotating paddle 5 moves the tea leaves on the conveyor belt, causing them to tumble and preventing them from remaining stationary. This effectively improves the drying effect. The drying tube 3 has exhaust holes 4, which are installed between adjacent paddles 5. The ratio of the area of the drying tube 3 to the total area of the exhaust holes 4 is 4:1. This maintains the rigidity of the drying tube 3 and ensures that hot air is evenly distributed to the tea leaves, while also preserving the heat inside the drying hood 2. A drive fan 6 is symmetrically installed inside the drying tube 3, allowing air to enter from both ends and rotate the tube. This saves on equipment manufacturing costs. The hot air flow drives the drying tube 3, making it convenient to use. Heating elements are symmetrically arranged on the drying hood 2, with equal spacing between them.
[0026] Specifically, through the combined use of the drying tube 3, the exhaust port 4, and the turntable 5, the drying tube 3 rotates during operation, causing the turntable 5 to rotate as well. This then turns over the flower tea on the conveying assembly 1, ensuring sufficient heat transfer and airflow exchange and even heating of the flower tea. This avoids the problem of inconsistent drying results caused by the flower tea remaining still on the conveying assembly 1 for a long time. At the same time, the exhaust port 4 rotates with the drying tube 3 and dries the flower tea while the turntable 5 turns it over, further improving the drying effect and avoiding inconsistent drying between the upper and lower layers of flower tea.
[0027] The heating element includes an air inlet box 7 fixedly installed on the drying hood 2. An installation block 10 is fixedly installed at the air outlet end of the air inlet box 7, forming a heating zone between the air inlet box 7 and the installation block 10. A heating wire 9 is fixedly installed in the heating zone, and an air intake fan 8 is fixedly installed in the heating zone. The air outlet end of the air intake fan 8 faces the heating wire 9. When the air intake fan 8 is working, air enters the air inlet box 7 from outside the equipment, is heated by the heating wire 9, and is then discharged into the drying tube 3. When the hot airflow passes through the drive fan 6, the hot air flow drives the drive fan 6 to work, further driving the drying tube 3 to rotate. This allows the turntable 5 to turn the flower tea on the conveyor belt, causing the flower tea to be turned over, thereby improving the drying effect of the flower tea and avoiding the problem of inconsistent drying effects between the upper and lower layers of flower tea.
[0028] The mounting block 10 is configured with a tapered channel, and the drying tube 3 is rotatably mounted on the mounting block 10. Utilizing the tapered channel within the mounting block 10, the hot air is pressurized as it passes through the mounting block 10, thus accelerating its flow towards the drying tube 3. This facilitates the operation of the drive fan 6, enabling the drying tube 3 to rotate normally and maintain the normal operation of the equipment. In turn, the combined use of the baffle plate 5 and the exhaust port 4 enhances the drying effect of the flower tea.
[0029] The air inlet of the drive fan 6 faces the mounting block 10, and the air inlet of the drive fan 6 shaft is set to be conical, so that when the hot air passes through the fan blades of the drive fan 6, the hot air can flow evenly between the adjacent fan blades, thereby driving the drive fan 6 to work, and then driving the drying tube 3 to work, which facilitates the operation of the drive plate 5 and the exhaust hole 4.
[0030] In this invention, the scented tea is first transported to the top of the conveyor belt via a feeding assembly. Then, the air intake fan 8 and heating wire 9 operate, allowing outside air to enter the drying chamber and heat it. The drive motor operates to move the conveyor belt, carrying the tea into the drying hood 2. When the tea moves to the bottom of the drying tube 3, the hot air flow drives the drive fan 6 to operate, the drying tube 3 rotates, and drives the turntable 5 to rotate. The rotating turntable 5 turns the tea over, and while the turntable 5 turns the tea over, the exhaust port 4 faces the tea and dries it, improving the drying effect. Subsequently, through multiple drying and turning processes, the tea is dried completely, effectively improving the drying effect of the tea.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
