Description

Technical Field

[0001] This utility model relates to the field of tea-making equipment technology, specifically to a multi-layer foldable tea withering trough. Background Technology

[0002] The tea withering trough is a key piece of equipment in the initial processing of tea, mainly used in the withering process. It typically consists of a rectangular trough, a ventilation system (such as fans and ducts), and a tea-holding mesh. Through controlled airflow and even spreading, it removes surface moisture from fresh leaves, promoting slow and uniform water loss from the leaves. This process activates enzymes in the tea leaves, driving the transformation of internal substances, and simultaneously releasing grassy odors to create a pleasant aroma. The withering trough significantly improves withering efficiency and stability, making it particularly suitable for large-scale production. It helps to standardize tea quality and lays an important foundation for subsequent processes such as rolling and fermentation. Traditional withering troughs have fixed dimensions, and their spreading area cannot be adjusted according to the amount of tea. When processing large quantities of tea, multiple withering troughs often need to operate simultaneously. However, for smaller quantities, they are very space-consuming and inconvenient to transport. A new type of withering trough is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a multi-layer foldable tea withering trough, comprising a frame that is divided into multiple levels from high to low and from wide to narrow. The outer walls of the side panels of the secondary frame are connected to the inner walls of the side panels of the upper frame via a sliding assembly, allowing the secondary frame to be completely retracted into the upper frame. Each level of the frame has a ventilation slot at its top, and an exhaust duct at the end of the ventilation slot. The exhaust duct is connected to an air supply assembly via a telescopic pipe. A withering box is hinged to the open side of the ventilation slot, and a tea-holding mesh is provided on the bottom surface of the withering box.

[0004] Furthermore, the sliding assembly includes a sliding groove formed on the inner wall of the cross-frame side plate, the end of the sliding groove extending to the lug on the edge of the cross-frame side plate, the upper sliding groove slidingly connecting to the slider on the outer wall of the secondary cross-frame side plate, the insertion hole in the center of the slider matching the position of the through holes at both ends of the sliding groove, and the pin passing through both the insertion hole and the through hole simultaneously positioning the secondary cross-frame.

[0005] Furthermore, the air supply assembly includes a blower, which is installed on the outer wall of the back plate of the top strut. The blower output end is connected to a distribution pipe, and the distribution pipe has several branch pipes with control valves. The branch pipes pass through the back plate and connect to the end of the telescopic pipe.

[0006] Furthermore, the first end of the telescopic tube is inserted into the exhaust duct and slidably connected to the inner wall of the duct. The exhaust duct opening contracts to restrict the complete withdrawal of the telescopic tube. When the secondary span frame is completely retracted into the upper span frame, the telescopic tube is fully compressed and inserted into the exhaust duct. When the secondary span frame is withdrawn from the upper span frame, the telescopic tube is withdrawn from the exhaust duct and extends.

[0007] Furthermore, handles are provided on the end face of the ventilation slot, pulleys are provided on the bottom surface of the side plates of each level of the span, and several exhaust ports with filters are provided on the body of the exhaust duct.

[0008] The beneficial effects of this utility model are as follows: This utility model is equipped with multi-level stackable and pull-out racks. Each rack is equipped with a withering box that can be folded and unloaded. The ventilation slots under each withering box are ventilated by the air supply component through the telescopic pipe. While ensuring the withering effect and spreading area, it improves the storage performance of the equipment, enables rapid transfer and arrangement, and can meet the withering needs of different tea quantities. It has the characteristics of strong applicability. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 3 As shown, a multi-layer foldable tea withering trough includes a frame 1, which is divided into multiple levels from high to low and from wide to narrow. Each level of the frame 1 has a pulley 108 on the bottom surface of its side plate. The outer walls of the side plates of the secondary frame 1 are connected to the inner walls of the side plates of the upper frame 1 through a sliding assembly. The sliding assembly includes a sliding groove 102 opened on the inner wall of the side plate of the frame 1. The end of the sliding groove 102 extends to the ear block 103 on the edge of the side plate of the frame 1. The upper sliding groove 102 is slidably connected to a slider 104 on the outer wall of the side plate of the secondary frame 1. The insertion hole 105 opened in the center of the slider 104 is matched with the through holes 106 at both ends of the sliding groove 102. The pin 5 passes through the insertion hole 105 and the through hole 106 to position the secondary frame 1.

[0014] In this embodiment, the secondary frame 1 can be completely housed within the upper frame 1. Each frame 1 has a ventilation slot 101 at its top. The withering box 4 is hinged to the open side of the ventilation slot 101. The bottom surface of the withering box 4 is provided with a tea-holding mesh 401. A handle 107 is provided on the end face of the ventilation slot 101. An exhaust duct 2 is provided at the end of the ventilation slot 101. The exhaust duct 2 has several exhaust ports 201 with filters on its body. The exhaust duct 2 is connected to the air supply assembly through a telescopic pipe 3. The air supply assembly includes a blower 6, which is installed on the outer wall of the back plate of the top span frame 1. The output end of the blower 6 is connected to the distribution pipe 7. The distribution pipe 7 has several branch pipes 701 with control valves. The branch pipes 701 pass through the back plate and connect to the end of the telescopic pipe 3. The first end of the telescopic pipe 3 is inserted into the exhaust duct 2 and slidably connected to the inner wall of the duct. The opening of the exhaust duct 2 contracts to restrict the telescopic pipe 3 from being completely pulled out. When the secondary span frame 1 is completely retracted into the upper span frame 1, the telescopic pipe 3 is completely compressed and inserted into the exhaust duct 2. When the secondary span frame 1 is pulled out from the upper span frame 1, the telescopic pipe 3 is pulled out and extended from the exhaust duct 2.

[0015] The working principle of this utility model is as follows: When withering is required, pull out the pin 5 to release each level of the spandrel 1. Use the handle 107 to pull out each spandrel 1 one by one. During this process, the telescopic tube 3, originally contained in the exhaust duct 2, is gradually pulled out and stretched until each slider 104 slides from the beginning to the end of the sliding groove 102, with the insertion hole 105 aligned with the through hole 106 at the end of the sliding groove 102. Insert the pin 5 to limit the movement, and lay the tea leaves onto the tea-holding mesh 401 of each level of the spandrel 1. Turn on the blower 6 to blow air into the distribution pipe 7. A heating wire can be installed in the distribution pipe 7 to control the airflow temperature. The airflow is regulated by the control valve and enters each branch pipe 701, then through the telescopic tube 3 and exhaust duct 2 into the ventilation slot 101, blowing on the tea leaves on the tea-holding mesh 401 and slowly removing moisture from the tea leaves. After withering is complete, fold over each withering box 4 to unload the tea leaves.

[0016] This utility model features a multi-level stackable and retractable frame 1. Each frame 1 has a withering box 4 that can be folded and unloaded. The ventilation slots 101 under each withering box 4 are ventilated by the air supply component through the telescopic pipe 3. While ensuring the withering effect and spreading area, it improves the storage performance of the equipment, enabling rapid transfer and arrangement. It can meet the spreading needs of different tea quantities and has strong applicability.
