ABSTRACT:
An improved doctoring knife for drum dryers and flakers of the type in which a product is deposited on a rotating drum and removed by action of the doctoring knife against the drum is disclosed. The improved doctoring knife is comprised of a series of knife blocks each having a cutting edge wherein the knife blocks are positioned adjacent to one another so that when the cutting edge of the knife block contacts the drum its bottom face will be in a plane substantially tangent to the line defined when the cutting edge contacts the drum. When a cutting edge is damaged the knife block containing the damaged edge can be removed and reground while undamaged knife blocks remain in position.
