Abrasive grains are also provided on the second grinding surface of the lower grinding block.

[0028] The method of using the present invention is described below:

[0029] (1) adding defatted soybeans into the shell through the feeding port, and the defatted soybeans fall on the discharge block and the carrying platform;

[0030] (2) The lifting cylinder moves to move the discharge block upward, and the upper grinding block and the lower grinding block move upward synchronously; the defatted soybeans fall from the gap between the discharge block and the supporting platform and fall on the upper grinding block; then the lifting cylinder moves in the opposite direction, so that the movable shaft and the discharge block, upper grinding block and lower grinding block on the movable shaft all move downward;

[0031] (3) The fine grinding motor starts to drive the main shaft and the movable shaft to rotate synchronously. At this time, the upper grinding block and the upper grinding table cooperate to grind the defatted soybean into fine particles;

[0032] (4) The lifting cylinder moves, causing the movable shaft to move upward again until the annular groove is connected to the circular hole of the upper grinding table. At this time, the soybean fine particles on the upper grinding table fall through the gap between the circular hole and the movable shaft and fall onto the lower grinding table;

[0033] (5) driving the lifting cylinder to move downward and driving the unloading motor to work again, so that the lower grinding block and the upper grinding block both rotate, and the lower grinding block cooperates with the lower grinding table to perform secondary grinding on the defatted soybean until the defatted soybean is finely ground into soybean powder;

[0034] (6) The unloading cylinder is driven to move the support block downward, so that the lower grinding table is separated from the lower grinding block, and then the unloading motor is driven to move the support block away from the bottom of the shell, and then the lifting cylinder is driven to move the lower grinding block upward. At this time, the soybean powder at the bottom of the shell passes through the bottom hole and falls into the collection box.
