Step S2, grinding to prepare powder: the drive abrasive disc rotates, drives the grinding rod and rotates and for slider reciprocating motion to drive grinding ball reciprocating motion in grinding bowl grinds the powder process to the probiotic caking.
In the specific process, the driving telescopic rod 21 is controlled to extend to enable the third driving wheel 20 to move to be in meshed connection with the connecting gear 23, and the driver 17 is started to rotate at a low speed. At this time, on one hand, the driver 17 drives the grinding disc 4 to rotate through the driving gear 22, the connecting gear 23, the third driving wheel 20 and the first driving wheel 18, so as to cooperate with the sliding block 5 to drive the grinding rod 2 to swing back and forth, and further drive the grinding ball 3 to grind the probiotic caking in the grinding bowl 1; on the other hand, the second driving wheel 19 is driven to rotate by the driving gear 22, the connecting gear 23, the transition wheel 24, the connecting wheel 25 and the rotating bevel gear 26, so that the grinding bowl 1 is driven to rotate, and then the grinding balls 3 are matched to grind the probiotic agglomerates in the grinding bowl 1. Meanwhile, in the process that the grinding disc 4 drives the grinding rod 2 to rotate, the second grinding bevel gear 9 rotates relative to the first grinding bevel gear 8, so that the spherical shell 31 is driven to rotate relative to the spherical center 32, friction rotation is formed between the steel ball 6 and the spherical center 32, and the probiotic powder adhered to the surface of the steel ball and the surface of the spherical center in the probiotic grinding process is cleaned in real time.
And S3, screening: and after finishing the grinding and milling in the step S2, driving the grinding bowl to rotate, forming centrifugal force in the grinding bowl, and enabling the ground probiotic powder to rise to the screen along the inner surface of the grinding bowl and penetrate through the screen to finish the screening operation of the probiotic powder.
Specifically, after the grinding operation of the probiotics in the step S2 is completed, the driving telescopic rod 21 is controlled to contract so that the third driving wheel 20 moves to be disengaged from the connecting gear 23, and the driver 17 is controlled to rotate at a high speed. At this time, the driver 17 drives the grinding bowl 1 to rotate at a high speed alone, so that the probiotic powder in the grinding bowl 1 gradually rises to the screen 10 along the inner surface of the grinding bowl 1 under the action of centrifugal force, and falls into the collecting barrel 11 through the screening of the screen 10, thereby completing the screening operation of the ground probiotic powder. Meanwhile, the protrusions 101 on the outer surface of the grinding bowl 1 are intermittently contacted with the knocking hammer 15 due to the rotation of the grinding bowl 1, so that the knocking hammer 15 is matched with the knocking elastic part 16 to repeatedly knock the grinding bowl 1 and the screen 10, the screen 10 is vibrated, and the screening effect of the probiotic powder is improved.
Step S4, collecting and blanking: after the screening in step S3 is completed, the probiotic powder passing through the screen mesh 10 is collected through the collection port 14 at the bottom of the collection barrel 11, and the blanking operation is completed.
After the sieving operation in step S3 is completed, the rotation of the driver 17 may be stopped or the rotation speed of the driver 17 may be reduced, and the probiotic powder that does not pass through the sieve 10 may slide down again into the grinding bowl 1 under the action of gravity to continue the grinding operation again.
