Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea fixing machines, and in particular to a tea fixing mechanism. Background Technology
[0002] Killing green is one of the initial processing steps for teas such as green tea, yellow tea, black tea, oolong tea, and pu-erh tea. Its main purpose is to destroy and deactivate the oxidase activity in fresh leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate some of the moisture in fresh leaves, soften the tea leaves, make them easier to roll and shape, and at the same time remove the grassy smell and promote the formation of good aroma.
[0003] Tea fixing is usually carried out in a fixing tank. In large-scale tea processing, carbon buildup is easily generated in the fixing tank. If it is not cleaned in time, it will affect the quality of subsequent tea and allow the burnt taste to enter the tea. However, large-scale tea processing pursues efficiency, and cleaning the fixing tank is time-consuming. The tea waiting for the batch to lose too much moisture will also affect the quality. Therefore, a tea fixing mechanism is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a tea fixing mechanism. The fixing tank is easy to replace. After each tank is processed, it can be removed and replaced with a new fixing tank. The used fixing tank can be cleaned. The stirring component can also be removed and replaced along with the tank lid. There is no carbon buildup that affects the quality of the tea and the processing efficiency of the equipment is not affected.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] This utility model discloses a tea fixing mechanism, comprising a base plate, a support column fixedly mounted on the top of the base plate, a cylinder rotatably connected to the top of the support column, a heating plate fixedly mounted on the inner wall of the cylinder, a stirring motor fixedly mounted on the right side of the cylinder, a rotating rod fixedly mounted at the output end of the stirring motor penetrating into the cylinder, a rectangular rod fixedly mounted on the left side of the rotating rod, a cover plate mounted on the left side of the cylinder, a connecting cylinder threaded into the cylinder being fixedly mounted on the right side of the cover plate and located inside the connecting cylinder, a stirring rod rotatably mounted on the right side of the cover plate and extending into the cylinder, the rectangular rod extending into the stirring rod and being connected to it for transmission, a stirring blade fixedly mounted on the outside of the stirring rod, a fixing cylinder sleeved on the outside of the rotating rod, and the stirring rod located inside the fixing cylinder.
[0007] As a preferred technical solution of this utility model, the inside of the blanching cylinder is provided with a rotating hole adapted to the rotating rod, and the outside of the blanching cylinder is provided with a vent hole that penetrates into the blanching cylinder.
[0008] As a preferred embodiment of this utility model, the base plate is a steel plate, and each of the four top corners of the base plate is threaded with a limiting screw that penetrates to the bottom of the base plate.
[0009] As a preferred embodiment of this utility model, the stirring blade includes a support rod and blades. The support rod is fixed at equal intervals at the top and bottom of the stirring rod, and the blades are fixedly disposed at the end of the support rod away from the stirring rod.
[0010] In a preferred embodiment of this invention, the connection between the support column and the cylinder is located slightly to the right of the cylinder's center of gravity, and the cover plate and the stirring rod are rotatably connected via bearings.
[0011] As a preferred embodiment of this utility model, a winding assembly is fixedly provided on the top of the base plate, a connecting block is fixedly provided on the right side of the cylinder, and a winding rope with one end fixedly connected to the connecting block is provided on the winding assembly.

[0024] In the attached diagram, all identical reference numerals refer to the same components.
[0025] Example 1
[0026] like Figure 1-5 As shown, this utility model provides a tea processing mechanism, including a base plate 1, which is made of steel plate. The top four corners of the base plate 1 are threaded with limiting screws 101 that penetrate to the bottom of the base plate 1. The limiting screws 101 fix the equipment to the ground to prevent the equipment from tipping over during use. A support column 2 is fixedly installed on the top of the base plate 1. A cylinder 3 is rotatably connected to the top of the support column 2. A heating plate 4 is fixedly installed on the inner wall of the cylinder 3. A stirring motor 5 is fixedly installed on the right side of the cylinder 3. A rotating rod 6 that penetrates into the cylinder 3 is fixedly installed at the output end of the stirring motor 5. A rectangular rod 7 is fixedly installed on the left side of the rotating rod 6.
[0027] In this embodiment, a cover plate 8 is provided on the left side of the cylinder 3, and a docking cylinder 11 threadedly connected to the cylinder 3 is fixedly provided on the right side of the cover plate 8 and inside the docking cylinder 11. A stirring rod 9 extending into the cylinder 3 is rotatably provided on the right side of the cover plate 8 and inside the docking cylinder 11. A rectangular rod 7 extends into the interior of the stirring rod 9 and is connected to it for transmission. A stirring blade 10 is fixedly provided on the outside of the stirring rod 9. The stirring blade 10 includes a support rod and a blade. The support rod is fixed at equal intervals at the top and bottom of the stirring rod 9. The blade is fixed at the end of the support rod away from the stirring rod 9. A blanching cylinder 12 is sleeved on the outside of the rotating rod 6, and the stirring rod 9 is located inside the blanching cylinder 12.
[0028] In addition, the inside of the blanching cylinder 12 is provided with a rotating hole that matches the rotating rod 6, and the outside of the blanching cylinder 12 is provided with a vent hole 121 that penetrates into the blanching cylinder 12.
[0029] It should be noted that the connection between the support column 2 and the cylinder 3 is located on the right side of the center of gravity of the cylinder 3, and the cover plate 8 and the stirring rod 9 are rotatably connected by bearings.
[0030] In this embodiment, a winding assembly is fixedly installed on the top of the base plate 1, and a connecting block 15 is fixedly installed on the right side of the cylinder 3. A winding rope 16 with one end fixedly connected to the connecting block 15 is provided on the winding assembly. The winding assembly includes a winding motor 13 and a winding reel 14. The winding motor 13 is fixedly installed on the top of the base plate 1, and the winding reel 14 is fixedly installed at the output end of the winding motor 13. The winding rope 16 is fixed and wound around the outside of the winding reel 14.
[0031] In summary, this utility model, by setting up a cover plate 8, a stirring rod 9, a stirring blade 10, a connecting cylinder 11, and a fixing cylinder 12, allows the cover plate 8 to be rotated and removed after fixing. The stirring rod 9 disengages from the rectangular rod 7, and the stirring rod 9 and stirring blade 10 are then removed. Subsequently, the fixing cylinder 12 is removed, and a new fixing cylinder 12 and cover plate 8 are replaced. The removed fixing cylinder 12 and stirring blade 10 are then cleaned. This ensures that the tea processing efficiency and subsequent tea quality are not affected. By setting up a support column 2, a winding motor 13, a winding reel 14, and a winding rope 16, the winding motor 13 drives the winding reel 14 to release the winding rope 16. The cylinder 3 begins to rotate counterclockwise due to gravity. The winding motor 13 drives the winding reel 14 to wind the winding rope 16, and the cylinder 3 rotates clockwise accordingly. By adjusting the inclination of the cylinder 3 during the fixing process, the tea is heated more evenly.
