Technical Field
[0001] This utility model relates to the technical field of black tea aroma enhancement equipment, and in particular to a black tea refining and aroma enhancement device. Background Technology
[0002] When refining black tea, it is necessary to enhance its aroma. Since black tea is already relatively dry during the refining process, if a rotary drum drying and aroma enhancement method is used, the continuous rotation of the drum during the aroma enhancement process will cause the black tea to break and be thrown inside the drum, affecting the quality of the black tea. Therefore, the tea tray method is generally used for aroma enhancement during the refining process.
[0003] For example, Chinese patent document CN114739137A, published on July 12, 2022, discloses a digitally controlled infrared energy-saving black tea drying and aroma-enhancing machine. This machine has multiple tea trays installed inside. During production, tea leaves are placed on the trays, and after aroma enhancement, the tea leaves are removed from the trays. Its advantages are: simple structure, easy use, and high degree of automation in integrated control. Its disadvantages are: after the aroma enhancement time is over, the inside of the machine still has a high temperature. Opening the door at this time causes a heat wave to escape, making it impossible for a person to approach the tea trays to remove the tea leaves. Furthermore, the tea leaves are still very hot, making manual removal inconvenient. Utility Model Content
[0004] The technical problem to be solved by this utility model is to solve the problems existing in the background art above and provide a black tea refining and aroma enhancement device. The tray is installed in the aroma enhancement box in a rotating manner. After the aroma enhancement is completed, the limiting device is opened to limit the tray, and the tray automatically flips over to pour out the tea leaves on the tray, which is convenient for the tea leaves on the tray to be taken out.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a black tea refining and aroma-enhancing device, including an aroma-enhancing box body, in which multiple trays are installed from bottom to top. Each tray has a frame on three sides and a discharge port on the other side. A rotating shaft is provided on the outer side of two opposite frames on the tray. The tray is rotatably connected to the inner wall of the aroma-enhancing box body through the rotating shaft. A limiting device is installed on the side wall of the aroma-enhancing box body. When the limiting device cooperates with the tray to limit it, the tray is in a horizontal state. When the limiting device separates from the tray, the end of the tray near the door of the aroma-enhancing box body flips downward.
[0006] The distance L2 from one end of the rotating shaft to the discharge port is greater than the distance L1 to the other end.
[0007] Support rods are installed on two opposite side walls inside the aroma box, and the tray is rotatably connected to the support rods on both sides via a pivot.
[0008] A hinge post is provided on the outer side of one of the two opposing frames of the tray, or on the outer side of both frames, and each hinge post is hinged to a hinge rod.
[0009] The limiting device is a hand-tightening bolt, which is screwed onto the side wall of the incense box. When the threaded end of the hand-tightening bolt abuts against the side of the tray, it limits the tray.
[0010] A limiting hole is provided on one side frame of the tray. The limiting device includes a sliding sleeve, a telescopic plug, a pull rod, a handle, and a spring. The sliding sleeve is fixedly installed on the inner wall of the incense box. The telescopic plug is slidably installed in the sliding sleeve. After the pull rod slides through the side wall of the incense box, one end is connected to the telescopic plug and the other end is connected to the handle. The spring is located in the sliding sleeve and is fitted on the pull rod. The limiting hole and the telescopic plug cooperate to limit the tray.
[0011] Limiting blocks are installed on the inner wall of the aroma-enhancing box.
[0012] The present invention has the following beneficial effects:
[0013] 1. The tray of this utility model is rotatably connected to the inner wall of the aroma-enhancing box via a pivot. A limiting device is installed on the side wall of the aroma-enhancing box. When the limiting device engages with the tray, the tray is in a horizontal position. When the limiting device separates from the tray, the end of the tray near the door of the aroma-enhancing box flips downwards. By rotating the tray inside the aroma-enhancing box, after aroma enhancement, the limiting device is opened to limit the tray, and the tray automatically flips under gravity, thus emptying the tea leaves from the tray, making it easy to remove.
[0014] 2. With the hinge rod installed, multiple trays can move simultaneously, requiring only one limiting device to limit all trays, making it more convenient to use. Furthermore, the consistent spacing between adjacent trays facilitates the pouring and spreading of tea leaves. Attached Figure Description

[0029] like Figure 1-8 As shown, a black tea refining and aroma-enhancing device includes an aroma-enhancing box 10. Multiple trays 20 are installed inside the aroma-enhancing box 10 from bottom to top. Three sides of each tray 20 have a frame 21, and the other side forms a discharge port 22. Two opposite frames 21 on the outer sides of each tray 20 are respectively provided with pivots 23. The trays 20 are rotatably connected to the inner wall of the aroma-enhancing box 10 via the pivots 23. A limiting device 30 is installed on the side wall of the aroma-enhancing box 10. When the limiting device 30 engages with the tray 20, the tray 20 is in a horizontal position. When the limiting device 30 separates from the tray 20, the end of the tray 20 near the door of the aroma-enhancing box 10 flips downwards. By rotating the trays 20 inside the aroma-enhancing box 10, after the aroma enhancement is completed, the limiting device 30 is opened to limit the trays 20, causing them to automatically flip under gravity, thus pouring out the tea leaves from the trays 20.
[0030] The aroma box 10 adopts existing technology, such as the device body in CN114739137A and the air intake system, air exhaust system and heat exchanger installed on the device body.
[0031] In one of the solutions, see Figure 7The distance L2 between the rotating shaft 23 and one end of the discharge port 22 is greater than the distance L1 to the other end. As a result, the weight at one end of the discharge port 22 will be greater than the weight at the other end. After the limiting device 30 is opened to limit the tray 20, the tray 20 will automatically flip under the action of gravity.
[0032] In addition to using the above structure to achieve automatic flipping of the tray 20, a weight can also be installed at the bottom on one side of the discharge port 22 to achieve automatic flipping of the tray 20 under the action of gravity.
[0033] Because the incense box 10 is a sheet metal structure and its side walls contain insulation material, it is inconvenient to install multiple bearing seats. Therefore, see [reference needed]. Figure 3 , 4 5. Support rods 11 are installed on two opposite side walls inside the incense box 10. The tray 20 is rotatably connected to the support rods 11 on both sides via a pivot 23. Specifically, the support rods 11 are provided with multiple holes, and the pivot 23 is fitted into the holes of the support rods 11 with clearance fit.
[0034] Further, see Figure 3-6 A hinge post 24 is provided on the outer side of one or both of the two opposing frame edges 21 of the tray 20. Each hinge post 24 is hinged to a hinge rod 40. This allows multiple trays to operate simultaneously, requiring only one limiting device 30 to control all trays 20, making it more convenient to use. Furthermore, the hinge rod 40 ensures consistent spacing between adjacent trays 20, facilitating the pouring and spreading of tea leaves. Specifically, the hinge rod 40 has multiple holes, and the hinge post 24 engages with these holes to achieve the hinge connection.
[0035] In one embodiment, the limiting device 30 is a hand-tightening bolt, which is screwed onto the side wall of the incense box 10. When the threaded end of the hand-tightening bolt abuts against the side of the tray 20, it limits the tray 20.
[0036] In another option, see Figure 8 A limiting hole 25 is provided on one side frame 21 of the tray 20. The limiting device 30 includes a sliding sleeve 31, a telescopic plug 32, a pull rod 33, a handle 34, and a spring 35. The sliding sleeve 31 is fixedly installed on the inner wall of the incense box 10. The telescopic plug 32 is slidably installed in the sliding sleeve 31. After the pull rod 33 slides through the side wall of the incense box 10, one end is connected to the telescopic plug 32, and the other end is connected to the handle 34. The spring 35 is located in the sliding sleeve 31 and is fitted onto the pull rod 33. When the telescopic plug 32 is inserted into the limiting hole 25, the limiting device 30 limits the tray 20 horizontally. When the telescopic plug 32 is pulled out, the tray 20 is released from the limiting device 30.
[0037] To prevent the tea leaves on tray 20 from being unevenly laid out, causing tray 20 to rotate in the opposite direction after being released from the limiting device 30, a limiting block 12 is installed on the inner wall of the aroma-enhancing box 10. (See attached image.) Figure 3 , 4 This prevents the tray 20 from rotating excessively in the opposite direction and also makes it easier to quickly align the limiting hole 25 with the telescopic plug 32 when the tray 20 returns to a horizontal state after rotating.
[0038] It should be noted that the spacing between the upper and lower trays can be increased as needed to facilitate the placement of tea.
[0039] The operation process or principle of this utility model is as follows:
[0040] When in use, the aroma-enhancing box of this utility model has a heating device, and the aroma-enhancing box has a hole for connecting the heating device.
[0041] First, insert the telescopic plug 32 into the limiting hole 25, and the limiting device 30 will horizontally limit the tray 20. Place the black tea to be enhanced on the tray 20. After placement, close the door and heat the tea to enhance its aroma.
[0042] After the aroma enhancement time is up, turn off the heating system, place the material frame at the bottom of the aroma enhancement chamber 10, open the chamber door, and then pull the handle 34 outwards. (See below) Figure 8 When the telescopic plug 32 moves outward, the spring 35 is compressed, and the tray 20 is released from the limit device 30. Since the discharge port 22 of the tray 20 is heavier at one end, the tray 20 automatically flips under the action of gravity, thereby pouring out the tea leaves on the tray 20. The tea leaves fall into the material frame below. Then, the tea leaves remaining at the bottom of the aroma-enhancing box 10 are cleaned into the material frame with a brush. During this process, the heat inside the aroma-enhancing box 10 is rapidly released.
[0043] After removing the material frame, manually move the tray 20 while simultaneously pulling the handle 34 outwards. Once the tray 20 is in a horizontal position, release the handle 34. The telescopic plug 32, under the action of the spring 35, extends into the limiting hole 25, and the tray 20 is locked in place. After this period of time, most of the heat inside the aroma box 10 has dissipated, and then black tea can be placed on the tray 20 again.
