Description

Technical Field

[0001] This utility model relates to the field of tea production, specifically a drum-type fixation machine for tea production. Background Technology

[0002] Fixing (or killing the green) is one of the initial processing steps for green tea, yellow tea, black tea, oolong tea, pu-erh tea, and some red teas. Its main purpose is to use high temperatures to destroy and deactivate the oxidase activity in fresh leaves, inhibit the enzymatic oxidation of tea polyphenols, evaporate some of the moisture from the leaves, soften the tea leaves for easier rolling and shaping, and simultaneously remove any grassy odor, promoting the formation of a pleasant aroma. It is also a crucial step affecting tea quality. While drum-type fixing machines use stirring to ensure the tea leaves are fully heated for fixing, current drum-type fixing machines feed from only one end, causing the tea leaves to accumulate at the feed end. This results in uneven heating, poor fixing efficiency, and an overall low fixing effect. Utility Model Content

[0015] Example 1 like Figure 1 and Figure 2As shown, a drum-type tea-processing fixation machine includes a base 1, a fixation cylinder 2 horizontally fixed on the base 1, a feeding mechanism at the top of the fixation cylinder 2, the feeding mechanism including a discharge cylinder 3 and discharge pipes 4, the discharge cylinder 3 being parallel to the fixation cylinder 2 and fixedly installed on the fixation cylinder 2, a screw conveyor assembly inside the discharge cylinder 3, a discharge hopper at one end of the top of the discharge cylinder 3, and multiple discharge pipes 4 connected axially to the bottom of the discharge cylinder 3, the ends of the discharge pipes 4 away from the discharge cylinder 3 being connected to the fixation cylinder 2, a stirring mechanism inside the fixation cylinder 2, and tea leaves to be fixed being fed into the discharge cylinder from the discharge hopper. Inside the 3, the tea leaves are conveyed along the axial direction of the fixing cylinder 2 by the auger conveyor assembly. The feeding cylinder 3 has a feeding hole corresponding to the feeding pipe 4, allowing the tea leaves to fall into the feeding pipe 4. The tea leaves enter the fixing cylinder 2 through the feeding pipe 4. By evenly conveying the tea leaves into the fixing cylinder 2, the tea leaves are stirred by the stirring mechanism inside the fixing cylinder 2, so that the tea leaves are heated evenly, thereby avoiding local accumulation of tea leaves and improving fixing efficiency and fixing effect. The stirring mechanism includes a rotating stirring shaft with multiple stirring blades fixed on the stirring shaft. The stirring shaft is driven by a motor, which is existing technology and will not be described in detail.

[0016] Furthermore, the auger conveyor assembly includes an auger shaft 18 and auger blades 19. The auger shaft 18 is rotatably connected to the feed cylinder 3, and the auger blades 19 are fixedly mounted on the auger shaft 18. An auger motor 20 is installed at one end of the feed cylinder 3. The output shaft of the auger motor 20 is connected to the auger shaft 18. The auger motor 20 drives the auger shaft 18 to rotate, and the auger shaft 18 drives the auger blades 19 to rotate, thereby conveying the tea leaves axially toward the fixing cylinder 2, so that the tea leaves gradually enter the fixing cylinder 2 through the feed pipe 4, achieving uniform feeding.
