[0026] In actual application of this embodiment, when the device is used to grind pancake rice paste, the cavity formed by the outer grinding disc 201 and the feed barrel 202 in the device is used to fill the rice paste to be grinded. When the device is driven, the driver 105 drives the conveying barrel 302 and the screw 305 to rotate independently. The conveying barrel 302 synchronously drives the inner grinding disc 307 thereon to rotate during the rotation process. The gap between the inner grinding disc 307 and the outer grinding disc 201 is set so that the rice paste in the feed barrel 202 flows along the gap. The rice slurry is rotated and crushed during the process, and the crushed slurry passes through the gap and drips into the centrifuge 306. Since the centrifuge 306 is fixedly arranged on the outer wall of the conveying cylinder 302, the rice slurry filled inside it rotates toward the slot side of the centrifuge 306 under the action of centrifugal force during the rotation of the centrifuge 306. When the slurry flows through the slot, it contacts the coarse filter 403 on the slot side. The coarse filter 403 is used to separate the rice slurry and the uncrushed rice. Under the action of centrifugal force, the refined slurry passes through the coarse filter 403. 03 and then swung into the feed trough 405, while the rice that has not passed through the coarse filter 403 is retained on the surface of the coarse filter 403 and is separated from one side of the notch of the centrifuge 306 as the coarse filter 403 rotates, and falls toward one end of the chassis 301 under the action of gravity. A screw 305 is rotatably arranged on the chassis 301, and the screw 305 can continuously lift the rice on the chassis 301 longitudinally along the conveying cylinder 302 during the rotation process, until the rice is discharged from the top of the conveying cylinder 302 and falls onto the outer grinding disc 20 again. 1 and the inner grinding disc 307, thereby achieving the re-grinding of rice, and the slurry sieved from one side of the coarse filter 403 is affected by the centrifugal force in the receiving box 404, and is thrown to the inner wall end of the outer cylinder 101 through the throwing pipe 406 on one side of the receiving box 404, and the rice slurry flows under the action of gravity and drips on the fine filter cloth 103, and the fine filter cloth 103 filters the excess water in the rice slurry and guides it to the return water drum 102, and the sieved rice slurry is trapped on the surface of the fine filter cloth 103 and can be manually taken out from one side of the discharge port 104.

[0027] In one case of this embodiment, the rotational linear velocity of the outer diameter end of the bottom plate 301 is much smaller than the rotational linear velocity at the notch position of the centrifuge 306, so the centrifugal force effect on the rice when it falls onto the bottom plate 301 is negligible.

[0028] See also Figure 2 In a preferred embodiment of the present invention, the shell structure 1 also includes a driver 105 and a support plate 106. The driver 105 is fixedly arranged on one side of the outer cylinder 101 and is fixedly connected to the conveying cylinder 302, and is used to drive the rotation of the conveying cylinder 302, the centrifuge 306 and the inner grinding disc 307. The support plate 106 is fixedly arranged on the inner wall side of the outer cylinder 101 and is arranged close to one end of the outer grinding disc 201.

[0029] In actual application of this embodiment, the driver 105 can synchronously drive the conveying cylinder 302 and the screw 305 to rotate during the rotation process, so that the slurry in the outer grinding disc 201 flows into the centrifuge 306 after grinding, and the slurry is separated by the coarse filter 403. The transmission ratios between the conveying cylinder 302 and the screw 305 and the driver 105 are not equal, so that the conveying cylinder 302 and the screw 305 rotate differentially, thereby realizing the longitudinal transportation of the rice slurry.

[0030] See also Figure 2 and Figure 4 In a preferred embodiment of the present invention, the grinding mechanism 2 also includes an adjuster 203 and a gear ring 204, one end of the adjuster 203 is fixedly connected to the outer grinding disc 201, and the other end of the adjuster 203 is movably assembled on the support plate 106, and the gear ring 204 is fixedly arranged on the bottom side of the outer grinding disc 201.

[0031] In actual application of this embodiment, the regulator 203 is movably assembled on the support plate 106 and fixedly connected to the outer grinding disc 201. By rotating the regulator 203, the gap between the outer grinding disc 201 and the inner grinding disc 307 can be adjusted, and the particle size of the rice slurry after grinding can be accurately adjusted according to production requirements. The gear ring 204 is fixedly set at the bottom of the outer grinding disc 201 and is set toward the side of the separation component 4.

[0032] See also Figure 2 In a preferred embodiment of the present embodiment, the return material assembly 3 also includes a return material cylinder 303, a groove plate 304 and a transmission wheel 308.

When the rice filtered out from one side of the coarse filter 403 falls into the return barrel 303, the rice can pass through the groove plate 304 and fall onto the chassis 301, and continue to approach the screw 305 during the continuous accumulation process. The screw 305 can continuously lift the rice in the conveying barrel 302 when rotating, so that the rice moves along the conveying barrel 302 toward the feeding barrel 202, so that the rice that does not meet the grinding particle size requirement re-enters the outer grinding disc 201 for grinding, thereby effectively improving the efficiency of rice slurry preparation.

[0034] See also Figure 3In a preferred embodiment of the present invention, the separation component 4 also includes a material receiving box 404, a material introduction trough 405 and a material throwing pipe 406.

A material throwing pipe 406 is also arranged at the other end of the material receiving box 404, and the material throwing pipe 406 is arranged toward the inner wall side of the outer cylinder 101.

[0035] In actual application of this embodiment, the material receiving box 404 is arranged between the first roller 401 and the second roller 402 and is arranged in contact with the coarse filter 403. The material guide groove 405 on one side of the material receiving box 404 is arranged on one side of the notch of the throwing tube 406, so that after the slurry centrifuged out of the centrifuge 306 is separated by the coarse filter 403, the large-particle rice component is retained on the surface of the coarse filter 403, and the small-particle slurry passes through the coarse filter 403 and the material guide groove 405 and flows into the material receiving box 404, and is thrown to the inner wall side of the outer cylinder 101 through the throwing tube 406 on one side of the material receiving box 404, so that the slurry naturally flows to the fine filter cloth 103 under the action of gravity.

[0039] In actual application of this embodiment, the scraper 503 on one side of the bracket 501 is elastically pressed onto the coarse filter 403 through an elastic member, so that the rice filtered off the coarse filter 403 can be scraped off by the scraper 503 and fall onto the surface of the scraper 503 when following the longitudinal movement of the coarse filter 403, and when the amount of rice on the scraper 503 continues to increase, part of the rice can roll along the scraper 503 onto the bracket 501, and pass through the bracket slot 502 and the slot plate 304 to fall onto the chassis 301, thereby realizing the recovery of large-particle rice.
