DETAILED DESCRIPTION
[0024] like Figure 1-6 In the invention, a dynamic withering machine based on tea processing includes a main support 1, on which a sub-support 2, a feed trough 4, a bearing connector 14 and a discharge trough 29 are provided. The bearing connector 14 is provided with a hollow rotating rod 15, which is connected to a dynamic withering cylinder 5 through a plurality of mounting fixtures 10. The hollow rotating rod 15 is provided with a plurality of groups of vents 16 and a transmission wheel 17, which is transmitted through a transmission belt 18 and a driving wheel 19, the driving wheel 19 is connected to the output end of a motor 20, the motor 20 is connected to the sub-support 2 through a fixing seat 21, the hollow opening end of the hollow rotating rod 15 is connected to a hot air structure, and a material receiving box 3 is provided below the main support 1.
[0025] In a preferred solution, the hot air structure includes an air duct 22 and a control seat 25, one end of which is connected to the hollow rotating rod 16, the other end of the air duct 22 is connected to the blowing device 23, and the control seat 25 is provided with a spiral heating element 24 covering the outer surface of the air duct 22. The hot air supply is stable, the temperature adjustment is flexible, and the practicability is strong.
[0026] In a preferred embodiment, the dynamic withering cylinder 5 comprises an intermediate cylinder 6, one end of which is provided with a closing cylinder 7, on which is provided an annular baffle 28, the other end of which is provided with an expansion cover 8, and the intermediate cylinder 6 is provided with a plurality of obliquely arranged unloading inclined plates 9. The cylinder structure with a large intermediate diameter can more effectively collect materials for processing and continuously and dynamically turn the materials.
[0027] In a preferred embodiment, a material blocking plate (30) is provided at one end of the discharge inclined plate (9) close to the expansion housing (8), and an end of the discharge inclined plate (9) away from the expansion housing (8) extends to the position where the diameter of the intermediate cylinder (6) is the largest. This can cooperate with the forward rotation process to continuously turn the material and prevent the material from sliding out of the discharge along the discharge inclined plate 9 during the turning process, and can also cooperate with the reverse guide discharge, which is convenient and flexible.
[0028] In a preferred solution, a protective cover 26 is provided on the control seat 25 to cooperate with the spiral heating element 24 to protect the heating position.
[0029] In a preferred solution, the installation fixture 10 includes a plurality of fixing sleeves 11 connected to a hollow rotating rod 15, a plurality of double-headed screws 12 are provided on the fixing sleeves 11, one end of the double-headed screw 12 is threadedly connected to the fixing sleeve 11, and the other end of the double-headed screw 12 passes through the dynamic withering cylinder 5 and is positioned and connected through a fixing nut 13.

[0030] In the preferred solution, the auxiliary support 2 is provided with a control panel 27, which is convenient to operate and highly practical.
[0031] The method of using the utility model is as follows: tea material is introduced into the dynamic withering cylinder 5 through the feed trough 4, and under the joint action of the hot air structure and the motor 20, the dynamic withering cylinder 5 rotates, and the material is continuously turned over by the hot air;
[0032] After withering is completed, the motor 20 flips and drives the dynamic withering cylinder 5 to rotate in the opposite direction. At this time, the unloading baffle 9 extends to the end of the middle cylinder 6 at the maximum diameter position, which will gradually guide the tea material so that it can be discharged through the baffle plate 30 along with the unloading baffle 9. During the withering process, since the dynamic withering cylinder 5 rotates forward, the tea material will not move along with the guidance of the unloading baffle 9. Even if a small amount of tea leaves are introduced onto the unloading baffle 9, they will still be blocked by the guide plate 30 and return to their original position, and continue to wither at the maximum diameter position of the middle cylinder 6.
