A fiber flow controlled centrifugal bowl mechanism comprises a centrifugal bowl and a mesh filter bracket sleeved at the bottom of the centrifugal bowl. A grating disk is installed between the bottom of the centrifugal bowl and the mesh filter. The upper surface of the grating disk is provided with cutting teeth, the lower part of the centrifugal bowl is provided with mesh holes allowing fibers to pass and the mesh size is adjustable. The utility model has the following advantages: 1, the centrifugal bowl and mesh filter of the juicer can rotate relatively to adjust the size of the mesh holes 2, the fiber flow can be controlled through the mesh holes, so beverages containing different fibers can be provided and 3, the mesh size can be quickly fixed by installing a locating structure, so the juicer is quick to adjust and convenient to use.
