Description

Technical Field

[0001] The invention relates to a multi-stage heat cycle drying device for Gongfu black tea and a drying method thereof, belonging to the technical field of tea processing devices. Background Art

[0002] There are many types of tea, and black tea is one of them. Black tea is a fully fermented tea. It is made from suitable new leaves of tea trees and is refined through a series of processes such as withering, rolling (cutting), fermentation, and drying.

[0003] During the processing of black tea, it needs to be dried. Drying is usually the last step in the processing of black tea. Its purpose is to quickly terminate the activity of enzymes in the tea leaves, fix the quality components in the leaves, and bring out the aroma. The drying process is divided into three stages: rough fire, full fire and aroma enhancement. The amount of water removed and the drying temperature in each stage decreases successively.

[0004] After searching, the Chinese invention patent with publication number CN112450287A discloses a multi-stage heat circulation drying device for black tea processing, the device includes a rough fire box, full fire boxes are welded on both sides of the rough fire box, the full fire box and the rough fire box are connected by a ventilation pipe 1, a drying component is placed inside the full fire box, a blower box is welded on the top of the rough fire box, a fan is fixedly connected to the inner wall of the blower box, an air intake mechanism is arranged above the fan and on the side wall of the blower box, an evenly distributed electric heating pipe is arranged below the fan, a ventilation pipe 2 is connected between the blower box and the rough fire box, and a solenoid valve 1 is arranged on the surface of the ventilation pipe 2; through the cooperation between the ventilation pipes, not only the air circulation from the rough fire box to the full fire box and then back to the rough fire box can be realized, but also the air circulation from the full fire box to the rough fire box and then back to the full fire box can be realized, and the air circulation direction can be converted according to the difference between the rough fire drying time and the full fire drying time, so as to meet the alternating cycle operation and reduce the discharge of hot air.

[0005] However, the device still has certain shortcomings: 1. Although the device can recycle the heat inside each firebox during processing, it will still cause a lot of heat to be wasted when replacing the drying process; 2. The device only uses a simple heating device to dry the tea leaves inside it, and the drying efficiency is relatively low, which affects the drying efficiency of the tea leaves; 3. When the device changes materials in each process, its internal temperature is relatively high, which causes certain harm to the health of the staff.

[0006] Therefore, we have made improvements to this and proposed a drying equipment for black tea processing. Summary of the invention

[0007] (I) The technical problems to be solved by the present invention are: 1. Although the existing device can recycle the heat inside each firebox to a certain extent during processing, it still causes a large amount of heat to be wasted when the drying process is replaced; 2. The existing device only uses a simple heating device to dry the tea leaves inside it, and the drying efficiency is relatively low, which affects the drying efficiency of the tea leaves; 3. When the existing device performs a material replacement operation in each process, the internal temperature is relatively high, which causes certain damage to the health of the staff.

[0029] S4: When the placement rack is inside the circulation drying mechanism, the second driving motor is started to drive the rotating seat connected to its output end to rotate, which in turn drives the gear ring connected to its inner wall to rotate, thereby driving the second gear meshing with it to rotate, and then driving the placement rack to rotate, so that the tea leaves on the placement rack can be heated more evenly, thereby improving the drying effect of the tea leaves. The spoiler can effectively make the hot air flow inside the circulation drying mechanism generate corresponding fluidity, improve the dispersion of the hot air flow, so that the tea leaves on the placement rack can be further heated evenly, thereby effectively improving the drying efficiency of the tea leaves;

[0030] S5: Through the set circulation pipeline, the hot air flow can be circulated among the raw fire drying chamber, the full fire drying chamber and the aroma drying chamber, and the waste heat of the raw fire drying chamber, the full fire drying chamber and the aroma drying chamber can be well recycled, reducing the outward discharge of hot air flow and avoiding heat waste.

6. The drying method of a drying device for black tea processing according to claim 5, characterized in that: The steps include: S1: During initial use, the placement rack is located inside the material change transition zone, the door is opened, and the tea leaves to be dried are placed on the placement rack, and the door is closed. The heating components are started at the same time, so that the heating components maintain the temperatures inside the rough fire drying chamber, the full fire drying chamber, and the aroma drying chamber, respectively, so as to dry the tea leaves well. S2: When the tea leaves in the material change transition zone need to be delivered into the circulation drying mechanism, the first driving motor is started to drive the cover plate connected to its output end to rotate, and the cover plate will drive the placement rack connected to it to rotate, and at the same time drive the teeth intermittently arranged on its outer wall to rotate. When the teeth rotate, they will drive the first gear meshing with it to rotate, thereby driving the rotating shaft to rotate, and then driving the winding wheel connected to its outer wall to rotate and wind up the cable. When the cable is wound up, it drives the telescopic assembly to shrink, and then drives the four sets of baffles that slide with each other to shrink. At this time, the circulating drying mechanism and its adjacent material changing transition zone will be connected to each other, the placement rack will rotate and the partition assembly will shrink at the same time, and then the placement rack and tea leaves inside the material changing transition zone will enter the circulating drying mechanism. After entering the circulating drying mechanism, the matching teeth and the first gear will miss each other. At this time, the partition assembly will separate the material changing transition zone and the circulating drying mechanism from each other through the reset elastic member. At this time, loading and unloading can conveniently avoid the situation where the temperature inside the circulating drying mechanism is too high and causes harm to the health of the staff; S3: When the tea leaves in the circulation drying mechanism need to be placed in the next process, the first driving motor is continuously started to drive the cover plate to rotate, and the placing rack and the partition assembly will repeat the operation process of step S2, and the placing rack and the tea leaves in the circulation drying mechanism are sent to the next material replacement transition zone for drying. Therefore, the drying equipment for black tea processing can effectively avoid the situation where a large amount of heat is wasted in the circulation drying mechanism when the drying process is replaced, and has a good environmental protection and saving effect; S4: When the placement rack is inside the circulation drying mechanism, the second driving motor is started to drive the rotating seat connected to its output end to rotate, which in turn drives the gear ring connected to its inner wall to rotate, thereby driving the second gear meshing with it to rotate, and then driving the placement rack to rotate, so that the tea leaves on the placement rack can be heated more evenly, thereby improving the drying effect of the tea leaves. The spoiler can effectively make the hot air flow inside the circulation drying mechanism generate corresponding fluidity, improve the dispersion of the hot air flow, so that the tea leaves on the placement rack can be further heated evenly, thereby effectively improving the drying efficiency of the tea leaves; S5: Through the set circulation pipeline, the hot air flow can be circulated among the raw fire drying chamber, the full fire drying chamber and the aroma drying chamber, and the waste heat of the raw fire drying chamber, the full fire drying chamber and the aroma drying chamber can be well recycled, reducing the outward discharge of hot air flow and avoiding heat waste. At the same time, the set fan and electromagnetic valve can effectively control the circulation of hot air flow and avoid damage to the tea leaves due to excessive temperature inside the circulation drying mechanism.
