Description

Technical Field

[0001] The utility model relates to the technical field of black tea airing devices, and particularly relates to a black tea uniform airing device. Background Art

[0002] The traditional tea preparation process mainly includes operations such as airing, dehydration, and stir-frying. As a widely used tea variety among traditional teas, black tea is also quite popular in modern tea-drinking cultures. Moreover, during the processing of black tea, chemical reactions centered around the enzymatic oxidation of tea polyphenols occur, resulting in significant changes in the composition of fresh leaves. The tea polyphenols are reduced by more than 90%, and new components and aroma substances such as theaflavins and thearubigins are produced, featuring black tea, red soup, red leaves, and a sweet and mellow taste. The Qimen black tea is relatively famous among black tea varieties. When preparing black tea leaves, air-drying is also a major process in its preparation and processing. To ensure the quality of black tea processing, uniform airing is required during airing to prevent uneven airing from affecting the subsequent preparation effect. During the existing tea spreading process, it is necessary to manually pour the tea leaves into the withering trough and then manually spread the tea leaves evenly, resulting in a very low spreading efficiency. Moreover, the process of collecting the aired tea leaves is rather troublesome. Therefore, we propose a black tea uniform airing device to solve the above problems. Content of the Utility Model

[0019] Further, the driving component includes a screw rod 6 and a nut sleeve 7. The screw rod 6 is rotatably installed inside the rotating groove 5. The left end of the screw rod 6 is threadedly installed with the nut sleeve 7. The nut sleeve 7 is fixedly connected to the front end of the sliding plate 8. As Figure 4 shown, the screw rod 6 is driven by the motor 4 to rotate inside the rotating groove 5, and the nut sleeve 7 drives the sliding plate 8 to slide on the upper side of the drying plate 2 under the action of the thread on the screw rod 6.

[0020] Further, a sliding groove is opened on the upper side of the rear end of the fixing frame 1, and a slider is slidably installed inside the sliding groove. The slider is fixedly connected to the rear end of the sliding plate 8. As Figure 3 shown, the stability of the sliding plate 8 when sliding on the upper side of the drying plate 2 is ensured by the setting of the slider.

[0021] Further, the locking component includes a spring 10, a limiting rod 11 and a limiting groove 12. Moving grooves are opened at both the front and rear ends of the fixing plate 9. The limiting rods 11 are movably installed inside the two moving grooves. The limiting rods 11 are movably inserted into the two moving grooves. The convex part of the limiting rod 11 is square. Limiting grooves 12 are symmetrically opened at both the front and rear ends of the sliding plate 8. The limiting grooves 12 are adapted to the convex part of the limiting rod 11. As Figure 4 shown, the setting of the two groups of locking components facilitates the quick disassembly and replacement of the fixing plate 9.

[0022] Further, a baffle 14 is movably inserted on the right side of the fixing frame 1, and a handrail is arranged on the upper side of the middle part of the baffle 14. As Figure 3 shown, the baffle 14 is provided to prevent the tea leaves from slipping off the right side of the fixing frame 1.

[0023] Further, a plurality of sets of combing rods 13 are arranged in an array at the lower ends of a set of fixing plates 9. A scraping plate 16 is fixedly connected to the lower ends of a set of fixing plates 9. Two sets of hooks 15 are arranged on the right side of the fixing frame 1. As Figure 3 and Figure 4 shown, the plurality of sets of combing rods 13 are provided to evenly spread out the tea leaves on the upper side of the drying plate 2. The scraping plate 16 is provided to facilitate the subsequent collection of the dried tea leaves. And the two sets of hooks 15 are provided to facilitate the hanging of a set of fixing plates 9 and the scraping plate 16, which is convenient for subsequent use.

[0024] Working principle: When the device is in use, the staff moves the device to the place where it needs to be used. Then the staff places the tea leaves to be dried on the upper side of the drying plate 2. Then the staff starts the motor 4, and the motor 4 drives the screw rod 6 to rotate inside the rotating groove 5. The nut sleeve 7 drives the sliding plate 8 to slide on the upper side of the drying plate 2 under the action of the thread. The sliding plate 8 drives a set of fixing plates 9 and a plurality of sets of combing rods 13 to slide on the upper side of the drying plate 2, so as to evenly spread out the tea leaves on the upper side of the drying plate 2. When the tea leaves are dried, the staff pulls the two limit rods 11 towards the middle of the fixing plate 9, and makes the convex parts of the two limit rods 11 taken out from the inside of the two limit grooves 12. Then the fixing plate 9 with a plurality of sets of combing rods 13 can be taken out from the middle of the sliding plate 8. Then the staff installs the fixing plate 9 with the scraping plate 16 installed on the lower side to the middle of the sliding plate 8. The staff pulls the two limit rods 11 towards the middle of the fixing plate 9, and the two limit rods 11 compress the two springs 10. After the staff aligns the fixing plate 9 and the sliding plate 8, the staff releases the two limit rods 11. The two limit rods 11 are ejected towards the front and rear sides under the elastic force of the two springs 10, so that the convex parts of the two limit rods 11 are inserted into the inside of the two limit grooves 12, thereby fixedly connecting the sliding plate 8 and the fixing plate 9. The staff places the collection basket on the right side of the fixing frame 1, and removes the baffle 14 from the right end of the fixing frame 1. The staff starts the motor 4, and the motor 4 drives the sliding plate 8 and the scraping plate 16 to slide on the upper side of the drying plate 2, so as to collect the tea leaves dried on the upper side of the drying plate 2 and collect them into the collection basket. The above is the whole working principle of the present utility model.

[0025] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
