Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea stir-frying device. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Other names include cha, jia, ming, and chuan. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, all of which are beneficial to health. Tea beverages are one of the world's three major beverages.

[0003] Common tea stir-frying equipment typically consists of a frame, a stir-frying pot, a heating system, and a stirring mechanism. The heating system heats up the pot, and the motor drives the stirring blades to rotate. The blades push the tea leaves inside the pot, bringing the tea leaves into contact with the heated surface of the pot, thus completing the stir-frying process.

[0004] Existing tea stir-frying equipment cannot guarantee that the tea leaves are stir-fried evenly and comprehensively. Ordinary stirring blades can only move the tea leaves in the middle area of ​​the pot, making it difficult to stir the tea leaves piled up at the bottom. This results in the tea leaves at the bottom not being heated for a long time, leading to uneven cooking. At the same time, the tea leaves tend to stick to the inner wall of the pot during the stir-frying process. The sticky tea leaves cannot participate in normal stirring, which not only affects the overall stir-frying uniformity, but also makes them prone to scorching due to local overheating, thus reducing the quality of the tea leaves. Therefore, a tea stir-frying device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tea stir-frying device, which aims to improve the problem of insufficient heating of the tea leaves at the bottom and uneven stir-frying in the prior art.

[0009] As a further description of the above technical solution:

[0010] The top of the outer casing is rotatably connected to a cover, and the bottom of the threaded rod contacts the top of the cover;

[0011] As a further description of the above technical solution:

[0012] The stirring assembly includes a drive motor, which is fixedly connected to the top of the cover. A rotating shaft is fixedly connected to the output end of the drive motor.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 Figure 2 and Figure 4This utility model provides an embodiment of a tea stir-frying device, comprising a base 1, a shell 3 fixedly connected to the top of the base 1, a sealing component installed on the outside of the shell 3, a stir-frying oven 8 fixedly connected inside the shell 3, and a stirring component installed inside the stir-frying oven 8; the sealing component includes a fixing block 14, which is rotatably connected to the outside of the shell 3, a connecting rod 13 rotatably connected to the middle of the fixing block 14, a threaded rod 16 threadedly connected to the middle of the connecting rod 13, and a handle 15 fixedly connected to the top of the threaded rod 16. A cover 4 is rotatably connected to the top of the shell 3, and the bottom of the threaded rod 16 contacts the top of the cover 4. During the stir-frying process, the tea emits a unique aroma. By rotating the handle 15, the bottom of the threaded rod 16 is brought into close contact with the cover 4, achieving a good seal for the stir-frying oven 8. The sealed stir-frying environment can prevent dust, impurities, microorganisms, and other external pollutants from entering the stir-frying oven 8, preventing the tea from being contaminated, ensuring the hygiene and safety of the tea, and meeting food quality standards. A resistance wire 7 is fixedly connected inside the outer shell 3, and is fixedly connected between the outer shell 3 and the stir-frying oven 8. When energized, the resistance wire 7 generates heat, raising the internal temperature of the stir-frying oven 8 and providing the necessary heat source for stir-frying the tea leaves, ensuring that the tea leaves can be processed in a suitable temperature environment. A feed hopper 5 is fixedly connected to the middle of the cover 4. A support column 2 is fixedly connected to the bottom of the base 1.

[0034] Reference Figure 3 The stirring assembly includes a drive motor 6, which is fixedly connected to the top of the cover 4. A rotating shaft 9 is fixedly connected to the output end of the drive motor 6, and a spiral stirring blade 10 is fixedly connected to the outside of the rotating shaft 9. When the drive motor 6 drives the rotating shaft 9 to rotate, the spiral stirring blade 10 also rotates. This spiral shape generates upward or downward thrust during rotation, causing the tea leaves to tumble inside the stir-frying oven 8, preventing the tea leaves from accumulating in only a localized area and achieving uniform heating. A connecting plate 18 is fixedly connected to the bottom of the rotating shaft 9, and a bottom plate 12 is fixedly connected to the bottom of the connecting plate 18. When the drive motor 6 drives the rotating shaft 9 to rotate, the bottom plate 12 rotates along with the rotating shaft 9, effectively stirring the tea leaves accumulated at the bottom of the stir-frying oven 8, allowing the tea leaves at the bottom to participate in the overall stir-frying motion, reducing the amount of tea leaves remaining in the stir-frying oven 8, and increasing the tea yield. A fixing rod 17 is fixedly connected to the middle of the rotating shaft 9, and a scraper 11 is fixedly connected to the outside of the fixing rod 17. The scraper 11 contacts the inner wall of the stir-fry oven 8. During the stir-frying process, some tea leaves may adhere to the inner wall of the stir-fry oven 8 for various reasons, which can easily lead to uneven heating. The scraper 11 can scrape off the tea leaves adhering to the inner wall and return them to the central area of ​​the stir-fry oven 8 to continue participating in stirring and stir-frying. This ensures that the tea leaves are heated evenly and prevents them from adhering to the inner wall for a long time, which could cause the tea leaves to burn and affect the quality of the stir-frying.

[0035] Working principle: By rotating the handle 15, the threaded rod 16 moves downward until its bottom is in close contact with the top of the cover 4, thus pressing the cover 4 tightly against the top of the outer shell 3 and sealing the stir-frying oven 8. Tea leaves are fed into the stir-frying oven 8 through the feed hopper 5. Then, the power is turned on to energize the resistance wire 7, causing it to heat up. The generated heat is transferred to the stir-frying oven 8, raising the internal temperature and providing a suitable temperature environment for stir-frying the tea leaves.

[0036] When the temperature inside the stir-frying oven 8 rises, the drive motor 6 is activated, driving the rotating shaft 9 to rotate. As the shaft 9 rotates, the spiral stirring blades 10, connecting plate 18, bottom plate 12, fixing rod 17, and scraper 11 also rotate. Due to its special spiral structure, the spiral stirring blades 10 cause the tea leaves to tumble inside the stir-frying oven 8 during rotation, ensuring the tea leaves fully contact the hot walls of the oven 8 for even heating. The bottom plate 12 stirs the tea leaves at the bottom of the stir-frying oven 8, preventing them from piling up and causing uneven heating. The scraper 11 contacts the inner wall of the stir-frying oven 8; during rotation, it scrapes off any tea leaves adhering to the inner wall, preventing them from burning due to prolonged contact with the oven wall and further ensuring the evenness of the stir-frying process.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
