DETAILED DESCRIPTION

[0022] like Figure 1-5 In the invention, a dynamic rehumidification machine for tea processing comprises a bracket 1, on which a mounting frame 2, a feeding frame 3 and a discharging trough 21 are provided, support bearings 4 are symmetrically provided on the bracket 1, a rotating shaft 8 is provided between the symmetrically provided support bearings 4, the rotating shaft 8 is connected to the rehumidification cylinder 7 through a connecting structure, a plurality of matching blades 24 are provided at one end of the rehumidification cylinder 7 close to the feeding frame 3 and the discharging trough 21, an air guide cavity is provided at one end of the rotating shaft 8, a plurality of groups of air holes 9 are provided at the location of the air guide cavity on the rotating shaft 8, one end of the rotating shaft 8 with the air guide cavity is matched with one end of the water supply pipe 6, the other end of the water supply pipe 6 is connected with the water vapor generating device 5, the other end of the rotating shaft 8 is connected with the transmission wheel 15, the transmission wheel 15 is matched with the driving wheel 17 arranged on the output end of the motor 18 through the transmission belt 16 for transmission, and the motor 18 is connected to the support plate 20 arranged on the mounting frame 2 through the fixing seat 19.

[0023] In a preferred solution, the connection structure includes two connection seats 10 arranged on the rotating shaft 8, and the two connection seats 10 are respectively provided with a plurality of first connecting rods 11 and second connecting rods 12 matched with the moisture recovery cylinder 7, and the first connecting rods 11 and second connecting rods 12 are provided with external threads at one end close to the connection seat 10 and are threadedly connected with the connection seat 10, and the other ends of the first connecting rods 11 and second connecting rods 12 pass through the moisture recovery cylinder 7 and are connected with the limit head 13. The assembly is matched, the connection is firm, and the rotation support is stable and practical.

[0024] In a preferred solution, a protective cover 22 is provided on the support plate 20 to cooperate with the transmission wheel 15, the transmission belt 16 and the driving wheel 17 to protect the transmission structure.

[0025] In a preferred solution, a material baffle 23 is provided on the side of the moisture reconditioning cylinder 7 away from the feed rack 3 to reduce the inflow of external impurities.

[0026] In a preferred embodiment, the diameter of the middle position of the moisture conditioning cylinder 7 is larger than the diameter of the two ends thereof, so as to limit the area of ​​tea moisture conditioning processing and avoid leakage of tea leaves.

[0027] In a preferred embodiment, the plurality of matching blades 24 are evenly arranged obliquely on the inner wall of the moisture conditioning cylinder 7. In coordination with the forward and reverse rotation of the moisture conditioning cylinder 7, the tea leaves can be turned over during the forward rotation and can be automatically unloaded during the reverse rotation.

[0028] In the preferred solution, the end of the matching blade 24 close to the discharge chute 21 is provided with a drainage inclined plate 14, and the other end of the matching blade 24 is in contact with the inner wall of the moisture recovery tube 7 and extends beyond the position of the maximum diameter of the moisture recovery tube 7.

[0029] The method of using the utility model is as follows: when the motor 18 rotates forward, the tea leaves are accumulated at the maximum diameter position in the moisture reconditioning cylinder 7. At this time, the tea leaves are continuously turned over by the gravity, the rotation of the moisture reconditioning cylinder 7 and the guidance of the blades 24 thereon, so as to fully contact and rehydrate with the water vapor sprayed from the air holes 9;

[0030] When the motor 18 reverses, the far end of the cooperating blade 24 is in contact with the inner wall of the rehumidification cylinder 7 and exceeds the maximum diameter position of the rehumidification cylinder 7. Therefore, during the reversal process, the cooperating blade 24 will continue to guide the tea material at the maximum diameter position of the rehumidification cylinder 7, so that it can flow and unload in an orderly manner through the cooperating blade 24 and the drainage inclined plate 14.

[0031] The beneficial effects of the utility model are as follows: relying on the uniform rotation of the cylindrical structure with a large middle diameter and small end diameters, the tea raw materials are kept dynamically tumbling in a limited area at all times, with comprehensive moisture regain and uniform quality; not only is it not easy to damage the tea materials, but it can also be in uniform contact with water vapor, fully improving the processing efficiency and controlling the moisture regain quality; the overall structure of the device is simple, and the unloading is convenient and fast by reversing the cylindrical structure and coordinating with the rotation of the blades, with a high degree of automation.
