1. the second motor 16 connected to the outer side of the bracket 2 is started, and the output shaft 161 of the second motor 16 drives the grinding roller 3 to turn over integrally at the lower part of the grinding box 4;

2. starting a first motor 9 connected to the other side of the bracket 2, driving a plurality of groups of stirring simulation hands 7 arranged on the inner central shaft 91 by the output end of the first motor 9, and installing a soft brush 8 at the end of each stirring simulation hand 7 to stir, fry and grind the spherical culture medium thrown in the grinding roller 3 from the feed port 31;

3. a plurality of crushing marbles 5 are put between a plurality of groups of stirring simulation hands 7, and the plurality of crushing marbles 5 are circularly and explosively flicked among spherical culture base materials under the drive of a plurality of crushing devices 6 arranged on the corresponding crushing marbles 5; and transferring the heat of the culture medium to the touched spherical culture medium;

4. when the spherical culture base material is stir-fried, a fan 15 connected with the outside of the grinding box 4 is started, the fan 15 is communicated with two vertical air pipes 12 to exhaust air, the outlet ends of the two vertical air pipes 12 are opposite to the lower part of the drying net 14 to blow hot air to the heating screen plate 10, and the heating screen plate 10 transfers heat to the inside of the grinding roller 3;

5. after the drying procedure is finished, the drawing-inserting type heating screen plate 10 is drawn, the heating screen plate 10 is communicated with the grinding box 4 when being drawn, the dried spherical culture base material falls onto a drying net 14, and is discharged through a discharge hole 11 formed in the side wall of the grinding box 4 above the drying net 14 after being stacked to a certain height.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the present invention as defined in the accompanying claims.
