Carrying out solid-liquid-liquid 3 phase separation,reduce the work of Centrifuge and avoid the waste of fish oil in slagging off. Thereby improve the production effeciency. Decrease the Centrifuge quantity and its investment;meanwhile reduce the frequency of regular cleaning Centrifuge; assure the continuous production. Drive by double transducer, with steady running, reliable performance and convenient operation. Large ratio on the bowl length and diameter, high RPM,with cone structure of bowl in various angles,assure of better separation performance.
