Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a continuous tea drying device. Background Art

[0002] Green tea refers to a beverage made from new leaves or buds of the tea plant, which have not been fermented and have been processed through processes such as withering, shaping, and drying. The color of the finished product and the tea soup after brewing mostly retain the green style of fresh tea leaves. Tea drying is one of the important steps in tea processing. It refers to the process of subjecting newly picked tea leaves to appropriate heat treatment to cause them to lose some of their moisture and reduce the humidity in the tea leaves to achieve the purpose of drying. Currently, the picked green tea is placed outdoors in a well-ventilated area or indoors in a well-ventilated area to allow the green tea to dry naturally. This method is low-cost and suitable for small-scale family or local production, but the drying speed is slow and is subject to environmental conditions. For example, humid weather can cause the tea leaves to dry slowly. Therefore, the present application provides a continuous tea drying device to meet this demand. Utility Model Content

[0031] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a continuous tea drying device, comprising a drying box 1, a drying drawer 5, an air duct 2, and a supporting mesh plate 6. The drying drawer 5 is slidably mounted on the drying box 1 and slides into the interior of the drying box 1. The upper surface of the drying box 1 has a plurality of independent drying chambers 4, and the plurality of independent drying chambers 4 are separated by fixed plates.

[0032] A supporting mesh panel 6 is fixedly mounted within the drying chamber 4. The bottom of the drying drawer 5 is open. The air duct 2 extends into the drying chamber 1 and is located below the drying drawer 5. The air duct 2 has a square-shaped structure. Intermediate tubes 8 are fixedly mounted inside the air duct 2. Multiple intermediate tubes 8 are arranged in an array and communicate with the air duct 2. Air outlet holes 17 are provided on the upper surfaces of the intermediate tubes 8 and the air duct 2, respectively. An air inlet pipe 7 is mounted on the outer wall of the air duct 2.

[0033] like Figures 3 to 5As shown, a drive screw 9 is horizontally mounted on the upper portion of the drying box 1, with its two ends rotatably connected to the drying box 1. A drive motor 3 is fixedly mounted on the outer wall of the drying box 1, with its output shaft fixedly connected to the drive screw 9. Multiple drive rods 10 are located on either side of the drive screw 10 within the upper portion of the drying box 1, with their ends fixedly connected to the inner wall of the drying box 1. A sliding beam 12 is threadedly mounted on the drive screw 9, with its ends sliding against the inner wall of the drying box 1. Multiple hybrid assemblies 11 are mounted on the sliding beam 12. The hybrid assemblies 11 comprise a rotating shaft 14 that passes vertically through and is rotatably connected to the sliding beam 12, a driven gear 15 fixed to the top of the rotating shaft 14, and multiple agitating rods 13 disposed on the outer surface of the lower end of the rotating shaft 14, extending into the inner side of the supporting mesh plate 6. The driven gear 15 is in contact with the drive rod 10, which has tooth grooves 16 adapted to accommodate the driven gears 15.

[0034] The working principle of the technical solution provided by this utility model is as follows:

[0035] When in use, first pull the drying drawer 5 out of the drying box 1, and then place the green tea that needs to be dried in the drying chamber 4 respectively. The green tea is separated and will not pile up, so that the tea leaves can be exposed to the hot air in a wider range during the drying process, thereby improving the drying efficiency. After the green tea is placed, the drying drawer 5 can be pushed into the drying box 1, and then the hot air is passed into the air duct 2 through the air inlet pipe 7. After entering the air duct 2, the heat spreads toward the inside of the intermediate tube 8 and enters the drying box 1 through the air outlet 17, and then comes into contact with the support mesh plate 6 in the drying drawer 5. At this time, the driving motor 3 is started, and the driving screw 9 is rotated. The sliding beam 12 threadedly connected to the driving screw 9 is forced to slide against the inner wall of the drying box 1, and in the process of sliding the sliding beam 12, the driven gear 15 moves in contact with the driving rod 10. Affected by the cooperation of the tooth groove 16 on the driving rod 10, the driven gear 15 rotates, thereby driving the rotating shaft 14 to rotate synchronously, and then the stirring rod 13 on the outer wall below the rotating shaft 14 rotates synchronously to stir the green tea inside the drying chamber 4. As the driving screw 9 rotates forward and turns, the stirring rod 13 stirs the green tea back and forth in the drying chamber 4, so that the tea can be continuously turned during the drying process, thereby improving the drying efficiency.
