In order to improve the granulation efficiency, the present invention optimizes the mixing process of powder and steam, shortens the time taken for the powder and steam to be fully mixed, and improves the overall granulation efficiency; the specific implementation process is as follows; the embodiment of the present invention is provided with a plurality of structures such as a rotating drum 21; when in use, the powder is injected into the mixing box 2 through the feeding assembly 11, and then the driving motor 34 is started, and the driving motor 34 drives the gear ring 32 to rotate through the gear 33; the gear ring 32 drives the rotating drum 21 to rotate, and the rotating drum 21 rotates. The rotating drum 21 drives the stirring tube 23 to rotate through the connecting piece 22. When the stirring tube 23 rotates in the stirring box 2, steam is filled into the rotating drum 21 through the external steam generator, the charging tube 31 and the charging head 3; the steam is filled into the stirring tube 23 through the connecting hole 211 and the connecting piece 22; then it is discharged into the stirring box 2 at different heights through the exhaust holes 231 on the surface of the stirring tube 23, and the steam is mixed with the powder at different heights, so that the steam is quickly mixed with the powder evenly; then, after the powder is evenly mixed, it is transferred to the granulation component 12 for granulation; the granulation process is completed; because the steam contacts the powder at different heights, the mixing speed of the steam and the powder can be increased, thereby improving the overall granulation efficiency.

[0023] An isolation cover 232 is provided at the opening of the exhaust hole 231, and a blocking block 233 is inserted at the opening of the isolation cover 232, and a return spring is provided between the blocking block 233 and the inner wall of the isolation cover 232; when in use, the isolation cover 232 and the blocking block 233 block the exhaust hole 231; then, as the stirring tube 23 rotates, the blocking block 233 is thrown out, and then the exhaust hole 231 is opened, so that steam is discharged, and the steam generates pressure in the stirring tube 23 and cooperates with the use of the blocking block 233 to prevent powder from entering the inside of the stirring tube 23; it is conducive to the normal use of the stirring tube 23.

[0024] A plurality of blocks 25 are provided on the surface of the stirring tube 23; when stirring the powder, the stirring tube 23 is controlled to rotate at a variable speed by the driving motor 34, so that the centrifugal force exerted on the blocking block 233 changes, so that the blocking block 233 intermittently hits the blocking block 25, thereby causing the stirring tube 23 to oscillate, causing the powder attached to the stirring tube 23 to fall off, and reducing the residue in the stirring box 2 when discharging the powder.

[0030] The bottom and top ends of the slider 41 are both rotatably provided with a plurality of rollers; when the gear ring 32 rotates, the slider 41 rotates relative to the annular slide rail 4, and the bottom and top ends of the slider 41 are both rotatably provided with a plurality of rollers, so that the slider 41 and the track of the annular slide rail 4 slide smoothly; thus preventing the annular slide rail 4 from shaking significantly; thus helping to improve the rotation stability of the rotating cylinder 21.
