ABSTRACT:
A method and apparatus for depithing bagasse fibers wherein a horizontal perforate surface such as a screen is provided with means for delivering bagasse onto a delivery end and the screen is given sudden vertical accelerations to accelerate the bagasse upwardly separating the pith from the fibers and driving the pith down through the perforations with the accelerations repeated at sequential localized areas along the screen.
