[0041] Working principle: When the solution of the present invention is used, after the beans are poured into the bean compartment 103, they pass through the inner side of the spray compartment 605 and enter the grinding kettle 201. The water in the water storage box 606 of the atomizing mechanism 6 enters the atomizing compartment 601 through a hose and is transformed into mist droplets under the action of the ultrasonic generating plate 602.

The worm shaft 205 drives the gear plate 204 to rotate, thereby making the upper flat blade disc 202 and the lower flat blade disc 202 realize coaxial and reverse rotation to grind the beans.

Under the action of the powder pushing block 208 and the guide plate 701, the bean powder smoothly slides into the powder outlet pipe 301 of the powder outlet mechanism 3 to be discharged. At this time, the plasma generator 501 is started, and plasma is generated inside the powder outlet pipe 301 through the conduction short rod 503. These plasmas have strong redox effects, and neutralize the charges on the surface of the bean powder and the grinding equipment to eliminate static electricity.

[0044] The powder pressing motor 405 of the powder pressing mechanism 4 drives the powder pressing block 401 to slide inside the annular shell 304 through the spur gear 403 and the vertical rack 402 to compact the bean powder and ensure that the bean powder can be discharged evenly and smoothly. When the bean powder gushes out, the splash-proof ring 303 forms a top barrier effect at the powder outlet of the powder outlet pipe 301, thereby greatly reducing the upward splashing of powder.
