Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea processing aroma enhancement device. Background Technology

[0002] Tea processing is the process of turning tea leaves (fresh leaves) into finished tea products through a series of techniques. The key steps in tea processing include picking, withering, fixing, rolling, drying, fermentation, and screening. Different types of tea (such as green tea, black tea, white tea, oolong tea, etc.) may have different processing focuses. For example, green tea focuses on maintaining the green color of the original leaves, while black tea requires a higher degree of fermentation.

[0003] The aroma enhancement process is a crucial step in tea processing, directly impacting the aroma and quality of the tea leaves. The withering (or fixing) stage has the most significant influence on aroma. However, uneven heating during the withering and roasting processes can lead to uneven aroma release. Furthermore, the lack of a relatively sealed structure allows aroma to easily escape, preventing the tea from retaining its aroma to the fullest extent. Therefore, this invention proposes a tea processing aroma enhancement device to address the problems mentioned in the background. Utility Model Content

[0014] 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.

[0015] Reference Figure 1-4 A tea processing and aroma-enhancing device includes a device box 1. A stir-frying pan 6 is rotatably connected inside the device box 1. A vent cover 7 is provided on the upper side of the stir-frying pan 6 and is rotatably connected inside the stir-frying pan 6. An electric heating element is installed inside the stir-frying pan 6. The vent cover 7 and the stir-frying pan 6 form a relatively closed tea stir-frying space. A stir-frying rod 14 is rotatably connected inside the stir-frying pan 6. The stir-frying pan 6 works with the internal stir-frying rod 14 to stir-fry the tea. The vent cover 7 inside the stir-frying pan 6 is turned off, tea leaves are put into the stir-frying pan 6, and then the vent cover 7 is turned off. The electric heating element inside the stir-frying pan 6 is connected to the power source, so that the stir-frying pan 6 heats up. The rotating stir-frying pan 6 works with the internal stir-frying rod 14 to roast and stir-fry the tea leaves to kill the green. The tea steam generated during the stir-frying is released into the device box 1 through the vent cover 7. Inside the device box 1, a rotating shaft 8 is rotatably connected to one side. A motor 4, mounted on the device box 1, is installed on one side of the blower 2. The output shaft of the motor 4 is fixedly connected to the rotating shaft 8. A partially faceted gear 13 is fixed to one side of the stir-fry pan 6. Another partially faceted gear 13 is fixed to the outer side of the stir-frying rod 14. The two partially faceted gears 13 are centered on the same rotating shaft 8. Two partially faceted gears 12 are fixed around the rotating shaft 8, meshing with the upper and lower partially faceted gears 13 respectively. When the motor 4 on the device box 1 is started, its output shaft drives the rotating shaft 8 to rotate. The rotating shaft 8 controls… The two incomplete gears 12 on the circumferential side rotate, and the two incomplete gears 12 drive the corresponding meshing incomplete end face gears 13 to rotate. Torsion springs are provided at the junction of the stir-fry pan 6 and the stir-frying rod 14. After the meshing of the incomplete gears 12 and the incomplete end face gears 13 is completed, the stir-fry pan 6 and the stir-frying rod 14 will rotate back to their original positions. Therefore, the rotating shaft 8, through the meshing incomplete gears 12 and the incomplete end face gears 13, enables the stir-fry pan 6 and the stir-frying rod 14 inside the device box 1 to rotate clockwise and counterclockwise within a certain angle, which can achieve efficient and rapid fixation of the tea leaves in the stir-fry pan 6. Inside the device box 1, there is a flow accumulation chamber 9 on the lower side, and a cooling element is installed inside the flow accumulation chamber 9. A return flow chamber 10 is set above the flow accumulation chamber 9. An exhaust fan 2 is fixedly installed on the upper part of the device box 1. The exhaust fan 2 is connected to the inside of the device box 1. A duct pipe 5 connects the exhaust fan 2 and the flow accumulation chamber 9. A door 3 is installed on the front side of the device box 1. When the exhaust fan 2 on the device box 1 is started, the exhaust fan 2 absorbs the tea vapor that has escaped into the device box 1 and conducts it to the flow accumulation chamber 9 below through the duct pipe 5. The low temperature in the flow accumulation chamber 9 can cause the water in the tea vapor to condense into water quickly and accumulate at the bottom of the flow accumulation chamber 9, while the aroma components of tea are retained. A valve port 15 is provided between the accumulation chamber 9 and the return chamber 10, and on the lower side of the accumulation chamber 9. Several vent ports 11 are provided on the upper side of the return chamber 10. A corresponding valve block 16 is provided inside each valve port 15. The valve block 16 is semi-circular, and the valve port 15 is a corresponding semi-circular shape. The upper and lower valve ports 15 are staggered, and both valve blocks 16 are fixed to the rotating shaft 8. During the continuous rotation of the rotating shaft 8, the rotating shaft 8 drives the two valve blocks 16 to rotate. When the upper valve port 15 opens, the lower valve port 11... 5. When the upper valve port 15 is opened, the retained tea aroma components enter the upper reflux chamber 10 through the valve port 15, and then enter the device box 1 through the vent 11, so that the tea leaves being stir-fried are soaked in the air containing tea aroma components, which can greatly improve the upper limit of the aroma during the tea stir-frying process. When the lower valve port 15 is opened, the upper valve port 15 is closed, which can prevent the aroma components from escaping to the outside of the device box 1, and the steam water in the accumulation chamber 9 is discharged accordingly.
