[0002] There are many tea-making processes in the production process of Liubao tea. Among them, the tea leaves of Liubao tea need to go through the process of pile fermentation, which means piling the tea leaves into a pile of a certain height, sprinkling water on them, and covering them with linen, so that the temperature inside the tea pile will gradually increase, thereby promoting the action of tea enzymes.

[0003] The equipment used in the current pile-fermenting process includes a steam box and several drawers. Before the pile-fermenting process begins, the staff spreads the tea leaves in each drawer and ensures that they are piled to a certain thickness. During the pile-fermenting process, the staff needs to open the drawer from time to time to observe the state of the tea leaves and measure the temperature in the steam box to ensure that the pile can be piled at an appropriate temperature.

[0004] However, in the process of opening the drawer to observe the state of the tea leaves and measuring the temperature in the steam box, the tea leaves need to be turned over and stirred so that they are heated evenly. This leads to uneven temperature of the tea leaves when manual intervention is not timely, thus affecting the effect of pile fermentation. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.

[0029] The Liubao tea leaf fermentation device provided in this embodiment is as follows: Figures 1 to 3 , a hood 1, a mesh cage 2, a driving member 4 and a hot steam component 5. The hood 1 is a hollow rectangular structure. An operating door 11 is provided on one side of the hood 1. In this embodiment, the number of the operating doors 11 is set to two, and both operating doors 11 are provided with an observation window 12, and the observation window 12 is closed by double-layer glass.

[0030] The mesh cage 2 is located inside the machine cover 1. The mesh cage 2 is made into a cylindrical shape by curling the metal mesh, and both ends of the length direction are closed by metal meshes of the same specifications. When the mesh cage 2 is made, a feed port 21 is cut out on one side of the mesh cage 2, and the cut sheet-shaped arc metal mesh is set as a closed mesh 22. The closed mesh 22 is hinged back to the surface of the mesh cage 2 for flipping. Before pile fermentation, the staff will open the closed mesh 22 and lay the tea leaves inside the mesh cage 2, and then fix the closed mesh 22 to the body of the mesh cage 2 by winding with iron wire.

[0031] In this embodiment, the number of driving members 4 is set to two, and both driving members 4 are existing rotating motors. Both driving members 4 are arranged on the top of the hood 1, and the two driving members 4 are respectively arranged near the two ends of the hood 1; both ends of the net cage 2 are fixedly provided with rotating sleeves 23, and the two rotating sleeves 23 are penetrated through the two side walls of the hood 1 and are rotatably installed with the two inner walls in the length direction of the hood 1. One of the rotating sleeves 23 is connected to the driving member 4 located on the same side through a pulley group, so that one of the driving members 4 can drive the net cage 2 to rotate.

[0032] In this embodiment, the rotating sleeve 23 is arranged in a tubular shape, and the stirring piece 3 is located inside the mesh cage 2. The stirring piece 3 includes a rod portion 31 and a plurality of leaf portions 32. The leaf portions 32 are evenly distributed along the length direction of the rod portion 31. The two ends of the rod portion 31 are passed through the two rotating sleeves 23 and rotatably installed on the two rotating sleeves 23. The end of the rod portion 31 away from the pulley group is connected to another driving member 4 through another group of pulley groups, thereby playing a role in controlling the mesh cage 2 and the stirring piece 3 to rotate respectively. When the stirring piece 3 and the mesh cage 2 rotate in opposite directions, it is beneficial to improve the uniformity of stirring the Liubao tea leaves.

[0033] The number of hot steam components 5 is set to four groups, and the four groups of hot steam components 5 are arranged around the mesh cage; the hot steam component 5 includes a water spray pipe 51, the water spray pipe 51 is horizontally arranged (parallel to the mesh cage) and both ends are fixedly installed on the inner walls of the two ends of the hood 1, one end of the water spray pipe 51 is closed, and the other end is passed through the side wall of the hood 1 to the outside of the hood 1. In this embodiment, the end of the water spray pipe 51 located outside the hood 1 is connected to the external hot water source through a adapter for pipe connection to facilitate the input of hot water.

[0034] Water outlet holes are provided on one side of the water spray pipe 51 facing the mesh cage 2. There are multiple water outlet holes 51, and the multiple water outlet holes 51 are spaced apart on the water spray pipe. The multiple water outlet holes 51 are all provided with atomizing nozzles 52, which is beneficial to ensure the uniformity of the sprayed water vapor. In order to reduce the risk of corrosion of the hood 1 due to water accumulation, a downpipe 13 is provided on one side of the hood 1 to facilitate drainage of the hood 1.

[0035] The implementation principle of the Liubao tea leaf pile fermentation device in the embodiment of the present application is: before pile fermentation, the staff opens the operating door 11 and the closed net 22 to spread the Liubao tea leaves as evenly as possible into the net cage 2, and then the operator covers the closed net 22 and fixes it with wire to prevent the closed net 22 from opening.

[0036] At this time, each atomizing nozzle 52 sprays hot water spray to the tea leaves through the water spray pipe 51. At the same time, the net cage 2 and the stirring member 3 rotate in opposite directions under the drive of the two driving members 4 to achieve the effect of wetting the Liubao tea leaves with hot water as much as possible, and then the tea leaves are stationary and begin to ferment.

[0037] During the pile fermentation process, the staff can control the two driving parts 4 and the hot steam components 5 to work, so as to maintain the uniformity of temperature and humidity in the machine cover 1 and the temperature distribution in the tea pile. The hot water spray sprayed by the hot steam component 5 will be discharged through the drain port, so as to reduce the accumulation of water in the machine cover 1.
