[0024] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0025] Working principle: first, pour the coffee bean raw materials into the storage tank 3 for concentration, then start the transmission motor 27 to drive the transmission shaft 22 to rotate, prompting the transmission bevel gear 23 to turn the reduction bevel gear 13, and then drive the hollow shaft 9 to rotate, and cooperate with the connection between the hollow shaft 9 and the turning plate 10, so that the turning plate 10 can turn the coffee bean raw materials, and cooperate with the setting of the linkage belt 26, so that the power of the transmission shaft 22 can be transmitted to the wind-making shaft 18, so that the wind-making shaft 18 drives the wind-making disk 19 to rotate, and introduces the external airflow into the wind-making cylinder 14, and at the same time starts the electric heating tube 17 to heat the airflow, and then the airflow is transmitted to the hollow shaft 9 through the transmission tube 15, and sprayed to the coffee bean raw materials through the air outlet 12, so that the coffee bean raw materials are in a completely dry state; The solenoid valve is opened to discharge part of the coffee bean raw materials in the storage tank 3 into the processing tank 6 and receive them through the material guide boss 30. At the same time, the driving motor 42 is started to drive the driving spur gear A43 to shift the matching spur gear B46, and the driving spur gear B44 to shift the matching spur gear B46, thereby driving the crushing shaft 35 and the grinding shaft 38 to rotate at the same time. With the connection between the grinding shaft 38 and the guide rod 40, the guide rod 40 can contact the inclined surface of the conductive frame 41 when rotating with the grinding shaft 38. With the continuous rotation of the guide rod 40, the conductive frame 41 can be pushed, so that the conductive frame 41 drives the displacement slide rod 32 to slide under the support of the positioning plate 31, so that the feeding boss 33 is away from the material feeding boss 33. The coffee bean raw materials received by the material guide boss 30 can reach the top of the pre-crushing carrier 29. When the guide rod 40 is separated from the conductive frame 41, the conductive frame 41 loses its support, so that the knocking plate 34 can fall toward the grinding roller 39 to initially crush the coffee beans. The coffee bean fragments that meet the specifications will fall onto the crushing carrier 28 through the through holes on the pre-crushing carrier 29, and the crushing cutter 36 can be used to cut the coffee bean fragments in conjunction with the rotation of the crushing shaft 35. The cut fragments will fall onto the surface of the blocking plate 48 through the through holes on the crushing carrier 28, and the pre-crushing carrier 29 can be used to crush the coffee bean fragments to generate powder in conjunction with the rotation of the grinding shaft 38. The self-locking motor 51 is started to drive the transmission screw 50 to rotate, and the transmission screw 50 is connected with the linkage shaft 53. Since the linkage shaft 53 is limited on the displacement frame 52 by the hydraulic rod 59, the linkage shaft 53 can drive the displacement frame 52 to move along the transmission screw 50. Since the guide plate 58 is assembled between the displacement frame 52 and the blocking disk 48, when the displacement frame 52 moves, the guide plate 58 can be used to pull the blocking disk 48 to rotate under the support of the extension seat 47, so that the blocking disk 48 is tilted, and the powder on the surface of the guide plate 58 will be discharged along the inclination of the blocking disk 48, and After the sealing disk 48 is adjusted, the hydraulic rod 59 can also be started to unlock the linkage shaft 53, so that the linkage shaft 53 can rotate on the displacement frame 52, and then the self-locking motor 51 is started to drive the transmission screw 50 to rotate. In conjunction with the connection between the displacement frame 52 and the transmission screw 50, the transmission screw 50 will drive the linkage shaft 53 to rotate on the displacement frame 52, and transmit the power of the linkage shaft 53 to the guide shaft 54 ​​through the synchronous belt 56, so that the guide shaft 54 ​​drives the eccentric plate 57 to rotate, so that the eccentric plate 57 knocks the sealing disk 48, and the compacted powder on the sealing disk 48 can be shaken off.
