The second drive motor 7 is controlled to work as a driving source. Under the drive of the second transmission belt 8, the conveying shaft 11 and the stirring shaft 9 are driven to rotate synchronously. The stirring shaft 9 is used to drive the stirring paddle 10 to dynamically stir and drive the mannose raw material in the loading bin 3 to keep the material falling dynamically to avoid accumulation and blockage. The conveying shaft 11 is used to drive the spiral conveying paddle 12 to spirally propel the mannose raw material falling into the loading barrel 2, and the material is quantitatively loaded into the unloading bin 4 through the unloading pipe 13 for crushing and granulation.

[0024] A crushing and granulating mechanism is arranged at the lower end of the support frame 1, and the crushing and granulating mechanism comprises a discharge bin 4 installed at the lower end of the support frame 1, and a guide plate 14, a crushing sleeve 17, and a screening mesh cylinder 18 are arranged in sequence from top to bottom inside the bin body of the discharge bin 4, and the guide plate 14, the crushing sleeve 17, and the screening mesh cylinder 18 are connected to each other. By utilizing the connection of the guide plate 14, the crushing sleeve 17, and the screening mesh cylinder 18, the mannose raw material is dropped between the extrusion rollers 15 through the guide plate 14, rolled into blocks, and then falls into the crushing sleeve 17, and is subjected to rotary cutting and crushing by the crushing roller 20, and finally falls into the screening mesh cylinder 18, and is subjected to rolling and granulation by the granulating roller 19, and is filtered and discharged through the screening mesh cylinder 18.

[0025] The discharge port of the guide plate 14 is symmetrically provided with two groups of squeezing rollers 15, the cylinder channel of the crushing sleeve 17 is provided with a crushing roller 20, the cylinder sleeve of the screening mesh cylinder 18 is provided with a granulating roller 19, and one end of the roller shaft of the granulating roller 19 is provided with a first driving motor 6 fixed on the discharge bin 4, and the granulating roller 19 is connected to the crushing roller 20 through a third transmission belt 21, and the crushing roller 20 is connected to the squeezing roller 15 through a first transmission belt 5.

[0026] The roller bodies of the two groups of extrusion rollers 15 are both spiral structures, and the two groups of extrusion rollers 15 are symmetrically meshed and driven by the mating gears 16 installed at one end of the roller shafts. When the mannose raw material is discharged to one end of the two groups of extrusion rollers 15 through the discharge pipe 13, the extrusion rollers 15 keep symmetrical rotation under the meshing of the mating gears 16, and then the symmetrical spiral rolling of the two groups of extrusion rollers 15 is used to roll and discharge the mannose raw material, and the powdered mannose raw material is squeezed into blocks.

When the mannose raw material circulates and falls into the unloading bin 4, the first driving motor 6 is controlled to work as a driving source, and under the transmission combination of the first transmission belt 5 and the third transmission belt 21, the squeezing roller 15, the crushing roller 20, and the granulating roller 19 are driven to operate synchronously, and the mannose raw material is rolled, crushed, and granulated in a layer-by-layer manner. When the sugar raw material is discharged to one end of the two groups of squeezing rollers 15 through the discharge pipe 13, the squeezing rollers 15 keep symmetrical rotation under the meshing of the matching gears 16, and then the symmetrical spiral rolling of the two groups of squeezing rollers 15 is used to roll and discharge the mannose raw material, and the powdered mannose raw material is squeezed into blocks. At the same time, the spiral rolling of the two groups of squeezing rollers 15 can spirally push forward and disperse the accumulated mannose raw material that has not been crushed in time, and gradually disperse it on the entire roller surface of the squeezing rollers 15. The entire roller surface of the squeezing rollers 15 is used to perform efficient roll-forming work on it, and then the roll-formed mannose raw material falls into the inside of the crushing sleeve 17, and the mannose raw material is crushed again by the rotary cutting of the crushing roller 20. Finally, the crushed mannose raw material falls into the screening mesh cylinder 18, and the granulating roller 19 is used to roll and granulate the mannose raw material evenly and quickly, thereby improving the granulation production efficiency and ensuring the product quality.
