[0022] The axial power of the top wall of the filter 7 is turned on to accelerate the filter 7 to the centrifugal speed, and the emulsion is injected into the discharge channel 4 through the injection channel 3. Since the distance between the outer end of the discharge channel 4 and the axial center is not less than 2 / 3 of the radius of the filter 7, the emulsion is discharged from the inner surface of the direct filter 7 after being guided by the discharge channel 4, and then passes through the filter 7 under the centrifugal action of the filter 7, and the impurities are retained inside the filter 7. The power of the cleaning shaft 2 is turned on, and the cleaning shaft 2 drives the spiral blades 6 and the spiral scraper 5 to rotate. The spiral blades 6 and the spiral scraper 5 drive the bristles to rotate, and the impurities retained in the filter 7 are scraped off and discharged through the impurity discharge bucket 8. Since there are gaps between the bristles and the speed of the cleaning shaft 2 is slow, the emulsion will not be discharged downward by the bristles, and the centrifuged emulsion is discharged through the milk discharge port 9 to complete the continuous production of clean milk.

[0023] The bristles on the outer edge of the spiral blade 6 fit in with the inner wall of the waste discharge bucket 8;

[0024] Prevent the inclined surface of the bucket 8 from being left over.

[0025] The injection channel 3 is located on the upper part of the filter screen 7, and the downward extension length of the injection channel 3 does not exceed 1 / 2 of the filter screen 7;

[0026] There is sufficient centrifugal space for the emulsion, so part of the emulsion will not be discharged through the bottom due to the guidance of the bristles.

[0027] In the gap between the filter 7 body and the inner wall of the shell 1, the upper surface of the impurity discharge bucket 8 and the inner surface of the bottom wall of the shell 1 are both inclined surfaces, and the milk discharge port 9 is connected to the lowest point of the inner inclined surface of the shell 1;
