Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea turning and drying machine. Background Technology

[0002] Turning and roasting tea leaves is a traditional tea processing technique primarily used to enhance the aroma and improve the quality of tea. During this process, the tea leaves are evenly spread on a drying rack or tray and then placed above a heat source for roasting. As the temperature gradually increases, the moisture in the tea leaves evaporates, and complex changes occur in the internal chemical components, such as reduced enzyme activity and oxidation of polyphenols. The key to successful turning and roasting lies in controlling the temperature and time; excessively high temperatures can cause the tea leaves to burn, while too low temperatures will fail to fully release their aroma. Through turning and roasting, the color, aroma, and taste of the tea leaves are significantly improved, making them more suitable for drinking and storage. This process requires not only rich experience and exquisite skills from the tea maker but also a deep understanding of the characteristics of tea.

[0003] However, using the current conventional method of turning and drying tea leaves, the amount of tea leaves that can be processed each time is inevitably small. This means that when turning and drying a large batch of tea leaves, the tea leaves need to be turned and dried multiple times, which is quite troublesome.

[0004] Therefore, a tea turning and drying machine is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tea-drying machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tea drying machine includes a casing that is closed on all sides and open on the top and bottom, an air guiding component that communicates with the inside of the casing, and a filter plate that is fixedly connected inside the casing. The filter plate has a plurality of ventilation holes. The top opening of the casing can be opened and closed. The air guiding component guides outside air into the casing and blows the tea leaves through the ventilation holes.

[0008] Preferably, an outwardly extending and horizontally arranged external support frame is fixedly connected to the edge of the top surface of the housing. Two bearing seats are fixedly connected to one end of the top surface of the external support frame. The inner rings of the two bearing seats are fixedly connected to a rotating shaft. The outer ring of the rotating shaft is fixedly connected to a sealing plate that can close the opening on the top surface of the housing.

[0009] Preferably, a handle is fixedly connected to the top surface of the end of the sealing plate away from the bearing seat.

[0010] Preferably, the bottom surface of the sealing plate is fixedly connected with a number of protrusions. When the sealing plate closes the opening on the top surface of the housing, the protrusions abut against the top surface of the outer support frame, and there is a gap between the sealing plate and the outer support frame and the top surface of the housing.

[0011] Preferably, the air guiding assembly includes an axial flow fan and an electric heating wire fixedly connected inside the axial flow fan, wherein the electric heating wire can be switched on and off.

[0012] Preferably, the air guiding assembly is connected to the housing via a flared tube, and the diameter of the flared tube gradually increases from the end facing the air guiding assembly.

[0013] Preferably, there is a gap between one end of the filter plate and the inside of the housing, and an arc plate located within the gap is fixedly connected to one end of the filter plate. The end of the arc plate away from the filter plate is fixedly connected to the top of the inner ring of the housing.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the operator places an appropriate amount of tea leaves into the machine casing and rotates the handle to allow the sealing plate to be supported by protrusions on the top surface of the machine casing and the top surface of the outer support frame, creating a ventilation gap to prevent the tea leaves from flying out. An electric heating wire heats the air in the axial flow fan, which guides the hot air into the machine casing, where it lingers to turn the tea leaves. After turning, the tea leaves are removed with a shovel; for small quantities, a curved plate is used to scrape them off to avoid waste. Attached Figure Description

[0026] A tea-drying machine, such as Figure 1 and Figure 2As shown, the device includes a housing 1 that is closed on all four sides and open on the top and bottom, an air guiding component that communicates with the interior of the housing 1, and a filter plate 8 that is fixedly connected inside the housing 1. The filter plate 8 has several ventilation holes. There is a gap between one end of the filter plate 8 and the interior of the housing 1. An arc plate 9 located within the gap is fixedly connected to one end of the filter plate 8. The end of the arc plate 9 away from the filter plate 8 is fixedly connected to the top of the inner ring of the housing 1. The opening on the top surface of the housing 1 can be opened and closed. The air guiding component guides outside air into the housing 1 and blows the tea leaves through the ventilation holes.

[0027] An outwardly extending and horizontally arranged external support frame is fixedly connected to the top edge of the housing 1. Two bearing seats 5 are fixedly connected to one end of the top surface of the external support frame 4. A rotating shaft is fixedly connected to the inner ring of the two bearing seats 5. A sealing plate 6 that can close the opening on the top surface of the housing 1 is fixedly connected to the outer ring of the rotating shaft. A handle 7 is fixedly connected to the top surface of the sealing plate 6 away from the bearing seats 5. Several protrusions are fixedly connected to the bottom surface of the sealing plate 6. When the sealing plate 6 closes the opening on the top surface of the housing 1, the protrusions abut against the top surface of the external support frame 4, and there is a gap between the sealing plate 6, the external support frame 4, and the top surface of the housing 1.

[0028] The air guiding assembly includes an axial flow fan 3 and an electric heating wire fixedly connected inside the axial flow fan 3. The electric heating wire can be turned on and off. The air guiding assembly is connected to the housing 1 through a flared tube 2. The diameter of the flared tube 2 gradually increases from the end facing the air guiding assembly.

[0029] In actual operation, the operator only needs to put a whole batch of tea leaves into the machine housing 1, ensuring that the amount of tea leaves is less than half the distance from the filter plate 8 to the top surface of the machine housing 1. Then, turning the handle 7 drives the sealing plate 6, which rotates through the shaft and bearing seat 5. At the same time, the bearing seat 5 and the shaft work together to restrict one end of the sealing plate 6, preventing it from shifting. At this point, the sealing plate 6 can finally be supported on the top surface of the machine housing 1 and the top surface of the outer support frame 4 through the protrusions. Furthermore, because the sealing plate 6 forms a gap between the top surface of the machine housing 1 and the top surface of the outer support frame 4 through the protrusions, air can be allowed to pass through. In this way, air can be allowed to pass through without tea leaves flying out from the gap. The situation is then addressed by energizing the heating wire, which heats the air in the axial flow fan 3. Under the operation of the axial flow fan 3, the hot air is guided into the machine casing 1 through the flared cylinder 2. Due to the increased cross-sectional area of ​​the airflow, the air velocity suddenly decreases, allowing the hot air to remain fully trapped inside the machine casing 1, thus completing the thorough turning and drying of the tea leaves. After the tea leaves have been turned and dried, they can be removed by the operator using a shovel. When the amount of tea leaves decreases to the point where they cannot be removed directly by the shovel, the remaining tea leaves can be scraped out of the machine casing 1 by the arc plate 9, thus avoiding waste of tea leaves.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
