Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and more specifically, to a multi-layer spreading and drying device for white tea withering. Background Technology
[0002] Sun-drying is a crucial step in traditional tea-making, accelerating water loss from fresh leaves and promoting the transformation of their internal substances through outdoor sun exposure. This method is widely used in the production of white tea, black tea, and oolong tea, utilizing the heat radiation and ultraviolet sterilization properties of sunlight to control moisture evaporation. The process requires sunny weather and regular turning of the leaves to ensure even sunlight exposure, but it suffers from limitations such as difficulty in controlling the intensity of sunlight and low production efficiency. Its process parameters (such as temperature and the amount of leaves spread) directly affect the aroma components of the tea (such as the floral and fruity aromas produced by polyphenol oxidation) and the quality of subsequent processing. Therefore, drying racks are needed to treat the tea leaves during this process.
[0003] However, in the use of existing multi-layer drying racks for white tea withering, the stacking of the racks from bottom to top can cause the upper racks, which are covered with tea leaves, to block the sunlight from the lower racks, resulting in insufficient drying of the tea leaves on the lower racks. In order to ensure that the tea leaves on the multi-layer drying racks can be fully dried, we have proposed a multi-layer spreading and drying device for white tea withering to solve the above-mentioned problems. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a multi-layer drying device for white tea withering. It pulls out multiple drying frames from the inside of the frame in different directions, then lays white tea on the support mesh of each drying frame, and moves the device into the sunlight to dry the white tea through the self-locking universal wheels at the bottom of the base. This effectively prevents the upper and lower layers from blocking sunlight, and allows the tea leaves on the multi-layer drying rack to be fully dried.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A multi-layer drying device for white tea withering includes a base and self-locking casters symmetrically installed at the bottom of the base. A frame is fixedly connected to the top of the base via a bracket.
[0009] The inner side of the frame is symmetrically and fixedly connected with a support frame, and multiple sets of the support frame are arranged longitudinally at equal intervals. The support frame is provided with guide holes.
[0010] A drying frame is installed above the support frame, and a support mesh is fixedly connected to the inner side of the drying frame. A guide post head is installed on the lower surface edge of the drying frame and is slidably connected to the guide hole. A limiting boss is installed at the bottom end of the guide post head, and the upper surface of the limiting boss is in contact with the bottom edge of the guide hole.
[0011] Furthermore, a reflector is provided below the supporting mesh, with its edge fixedly connected to the drying frame.
[0012] Furthermore, the upper surface of the reflector is coated with a mirror coating, and the thickness of the mirror coating is set at 0.01-0.02 mm.
[0013] Furthermore, the support frame is specifically provided in four sets, and the four sets of support frames are arranged vertically and interactively in pairs.
[0014] Furthermore, the supporting mesh is composed of radial stainless steel wires and weft stainless steel wires, and the radial stainless steel wires and weft stainless steel wires are interwoven and connected.
[0015] Furthermore, the outer wall of the guide post is coated with a wear-resistant coating, and the wear-resistant coating is in contact with the inner wall of the guide hole.
[0016] Furthermore, the frame, support frame, and drying rack are all made of stainless steel.
[0017] 3. Beneficial effects
[0018] Compared with existing technologies, the advantages of this utility model are:
[0019] (1) In this scheme, by dragging the drying frame, the guide column head slides in accordance with the guide hole opened on the support frame until the end of the guide column head abuts against the guide hole. The guide column head is limited by the limiting boss to prevent the guide column head from dislodging from the guide hole. Multiple drying frames are pulled out from the inside of the frame from different directions. Then, white tea is laid on the support mesh of each drying frame. The device is moved to the sun to dry the white tea by the self-locking universal wheels at the bottom of the base. This can effectively prevent the upper and lower layers from blocking the sunlight and ensure that the tea leaves on the multi-layer drying rack can be fully dried.
[0020] (2) In this scheme, after the sunlight passes through the supporting mesh, the mirror coating on the reflector reflects the sunlight, so that the sunlight shines on the other side of the tea leaves, which can effectively improve the drying effect, shorten the drying time, and improve the drying efficiency.

[0029] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0030] Example:
[0031] Please see Figure 1-6 A multi-layer drying device for white tea withering includes a base 1 and self-locking casters 2 symmetrically installed at the bottom of the base 1. A frame 3 is fixedly connected to the top of the base 1 by a bracket.
[0032] The inner side of the frame 3 is symmetrically and fixedly connected with a support frame 4, and multiple sets of support frames 4 are arranged longitudinally at equal intervals. The support frame 4 is provided with a guide hole 5.
[0033] A drying frame 6 is installed on the top of the support frame 4. A support mesh 7 is fixedly connected to the inner side of the drying frame 6. A guide post 8 that is slidably connected to the guide hole 5 is installed on the lower edge of the drying frame 6. A limiting boss 9 is installed at the bottom of the guide post 8, and the upper surface of the limiting boss 9 is in contact with the bottom edge of the guide hole 5.
[0034] It should be noted that when using this multi-layer drying device for white tea, the guide column 8 is slid along the guide hole 5 on the support frame 4 by dragging the drying frame 6 until the end of the guide column 8 abuts against the guide hole 5. The guide column 8 is then limited by the limiting boss 9 to prevent it from dislodging from the guide hole 5. Multiple drying frames 6 are pulled out from the inside of the frame 3 from different directions. White tea is then laid on the support mesh 7 of each drying frame 6. The device is then moved into the sunlight by the self-locking casters 2 at the bottom of the base 1 to dry the white tea. This effectively prevents the upper and lower layers from blocking sunlight and ensures that the tea leaves on the multi-layer drying rack are fully dried.
[0035] like Figure 4 As shown, a reflector 10 is provided below the supporting mesh 7, with its edge fixedly connected to the drying frame 6. The upper surface of the reflector 10 is coated with a mirror coating, and the thickness of the mirror coating is set at 0.01-0.02mm.
[0036] It should be noted that after sunlight passes through the supporting mesh 7, the mirror coating on the reflector 10 reflects the sunlight, so that the sunlight shines on the other side of the tea leaves, which can effectively improve the drying effect, shorten the drying time, and improve the drying efficiency.
[0037] like Figure 2 As shown, the support frame 4 is specifically provided in four sets, and the four sets of support frames 4 are arranged vertically and interactively in pairs.
[0038] It should be noted that multiple drying racks 6 can be pulled out from the inside of the frame 3 from different directions, and then white tea can be laid on the supporting mesh 7 of each drying rack 6, which can effectively prevent the upper and lower layers from blocking sunlight.
[0039] like Figure 5 As shown, the support mesh 7 is composed of radial stainless steel wires and weft stainless steel wires, and the radial stainless steel wires and weft stainless steel wires are interwoven and connected.
[0040] It should be noted that this ensures the breathability of the tea leaves, which can effectively improve the drying effect of white tea.
[0041] like Figure 4 As shown, the outer wall of the guide column head 8 is coated with a wear-resistant coating, and the wear-resistant coating is in contact with the inner wall of the guide hole 5.
[0042] It should be noted that this can effectively reduce the wear between the guide pin 8 and the guide hole 5, thereby improving the service life of the guide pin 8.
[0043] Frame 3, support frame 4 and drying rack 6 are all made of stainless steel.
[0044] In use: By dragging the drying frame 6, the guide column 8 slides in accordance with the guide hole 5 on the support frame 4 until the end of the guide column 8 abuts against the guide hole 5. The guide column 8 is then limited by the limiting boss 9 to prevent it from dislodging from the guide hole 5. Multiple drying frames 6 are pulled out from the inside of the frame 3 from different directions. Then, white tea is laid on the support mesh 7 of each drying frame 6. The device is moved to the sun to dry the white tea by the self-locking casters 2 at the bottom of the base 1. This effectively prevents the upper and lower layers from blocking the sunlight, allowing the tea leaves on the multi-layer drying rack to be fully dried.
[0045] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
