Description

Technical Field

[0001] This utility model relates to the field of black tea fermentation technology, specifically to a device for fermenting dandelion black tea. Background Technology

[0002] Dandelion black tea requires fermentation during its production, a crucial step in shaping its color, aroma, and flavor. Fermentation works by controlling temperature and humidity to promote the process within the tea leaves. Black tea fermentation equipment is not only used for individual black tea production but is also widely employed in tea production and processing plants to improve the quality and yield of black tea. This equipment plays a vital role in black tea production; it controls the conditions during fermentation, providing an ideal environment for the tea leaves to ferment to their optimal state. This not only enhances the taste and aroma of the black tea but also increases its value and market competitiveness.

[0003] Currently, traditional dandelion black tea fermentation often results in dead zones during the stirring process. While the dandelion black tea leaves move to enhance fermentation, those that remain stagnant cannot be stirred, leading to uneven fermentation and affecting the quality of the tea. To address this, we propose a dandelion black tea fermentation device. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a fermentation device for dandelion black tea. In use, dandelion black tea material is placed into the cylinder through the inlet. Under the action of an electric heating rod controlled by a temperature control switch and a spraying component, the dandelion black tea material begins to ferment. Simultaneously, the drive component rotates the first and second rotating shafts. The rotation of the first shaft drives a stirring rod to stir and fry the dandelion black tea material. At the same time, the rotation of the second shaft drives a gear, which in turn drives a gear ring and the cylinder to rotate. Thus, the dual rotation of the stirring rod and the cylinder enhances the fermentation effect of the dandelion black tea material, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fermentation device for dandelion black tea, comprising a box, a cylinder, a spraying assembly, and a driving assembly;

Multiple spray holes are evenly distributed on the outer surface of the first rotating shaft, and these spray holes are connected to the guide groove. The water pump is controlled by an external controller, which pumps water from the water tank into the guide groove through the water pipe, where it is sprayed onto the dandelion black tea material by the spray holes.

[0009] Furthermore, the drive assembly includes a belt, a first pulley mounted on the right end of the first rotating shaft, and a second pulley mounted on the second rotating shaft. The first and second pulleys are connected via belt drive. A motor bracket is mounted on the right side of the housing, and a motor is mounted on the motor bracket.

A liquid spraying assembly is connected to the left end of the first rotating shaft 14. Multiple sets of stirring rods 10 are evenly mounted on the outer surface of the first rotating shaft 14 along the axial direction. Each set of stirring rods 10 includes three stirring rods 10 evenly mounted on the outer surface of the first rotating shaft 14. Multiple vent holes 19 are evenly opened on the outer surface of the cylinder 9. A gear ring 7 is mounted on the outer surface of the cylinder 9. A second rotating shaft 20 is rotatably mounted on the lower side of the box body 1. A gear 18 is mounted on the second rotating shaft 20. The gear 18 and the gear ring 7 are meshed and connected. The drive assembly is connected to the first rotating shaft 14 and the second rotating shaft 20 respectively. Multiple electric heating rods 17 are evenly mounted inside the lower part of the box body 1. The input end of the electric heating rod 17 is electrically connected to the output end of the temperature control switch.

[0018] In use, dandelion black tea material is placed into the cylinder 9 through the feed inlet. Under the action of the electric heating rod 17 controlled by the temperature control switch and the action of the spraying component, the dandelion black tea material begins to ferment. At the same time, the drive component works to drive the first rotating shaft 14 and the second rotating shaft 20 to rotate. The rotation of the first rotating shaft 14 drives the stirring rod 10 to work, and the stirring rod 10 stirs and stirs the dandelion black tea material. Meanwhile, the rotation of the second rotating shaft 20 drives the gear 18 to rotate, and the rotation of the gear ring 7 and the cylinder 9 to rotate. Thus, the fermentation effect of the dandelion black tea material is improved under the dual rotation action of the stirring rod 10 and the cylinder 9.

[0019] The spraying assembly includes a water tank 3 mounted on the upper surface of the housing 1, a water pump 8 installed at the outlet of the water tank 3, a water pipe 2 installed at the outlet of the water pump 8, a guide groove 11 on the left side of the first rotating shaft 14, and the right end of the water pipe 2 rotatably connected to the inner wall of the guide groove 11.

[0020] The drive assembly includes a belt 5, a first pulley 4 mounted on the right end of the first rotating shaft 14, and a second pulley 6 mounted on the second rotating shaft 20.

The rotation of the second pulley 6, under the action of the belt 5, drives the first pulley 4 to rotate. The rotation of the first pulley 4 drives the first rotating shaft 14 to rotate, thus completing the rotation of the first rotating shaft 14 and the second rotating shaft 20 electrically.

[0021] The working principle of the dandelion black tea fermentation device provided by this utility model is as follows: In use, dandelion black tea material is placed into the cylinder 9 through the feed inlet. Under the action of the electric heating rod 17 controlled by the temperature control switch and the spraying assembly, the dandelion black tea material begins to ferment. Simultaneously, the drive assembly drives the first rotating shaft 14 and the second rotating shaft 20 to rotate. The rotation of the first rotating shaft 14 drives the stirring rod 10 to stir and stir the dandelion black tea material. At the same time, the rotation of the second rotating shaft 20 drives the gear 18 to rotate, which in turn drives the gear ring 7 and the cylinder 9 to rotate. Thus, the fermentation effect of the dandelion black tea material is enhanced by the dual rotation of the stirring rod 10 and the cylinder 9. The water pump 8 is controlled by an external controller. The water pump 8 pumps water from the water tank 3 into the guide channel 11 through the water pipe 2, and sprays it onto the dandelion black tea material through the spraying holes. The motor 15 is controlled by an external controller. The motor 15 drives the second shaft 20 to rotate. The rotation of the second shaft 20 drives the second pulley 6 to rotate. The rotation of the second pulley 6, under the action of the belt 5, drives the first pulley 4 to rotate. The rotation of the first pulley 4 drives the first shaft 14 to rotate. Thus, the rotation of the first shaft 14 and the second shaft 20 is completed electrically.
