The patent application is concerned with an apparatus and system comprised of a plurality of doctoring units, each of which is a pivotally supported combination doctor blade and V-shaped member. In each unit the leading edge of the doctor blade is parallel to the plane of the surface of a processing belt. This conveys the material to be dried and the leading edge formed by the two plane faces of the V-shaped member is generally perpendicular to the plane of the belt when the unit is in doctoring position. In addition to doctoring, the apparatus and system imparts a tumbling action to the material being dried by the plowshare action of the V-shaped member.
