Title: Material storage and feeding device

Abstract: A material feeding device for storing and feeding material and especially granulated material such as sawdust, wood chips, nut shells, or corn cobs at a controlled rate. The device includes a hopper which is preferably tapered toward its outlet end and a drive assembly which revolves a radial rotor arm carrying a rotating agitator toward the material at a controlled rate for loosening of the material. The rotatable agitator has outward projections and extends through the hopper. Such revolution and rotation of the agitator prepares the material by release by loosening and moving the material in the hopper upwardly allowing it to fall freely downwardly under gravity through the hopper outlet. If desired, the direction of rotation of the agitator may be reversed to force the material downwardly. Revolution and rotation of the agitator may also be controlled with an adjustable brake assembly. The agitator may be heated to loosen it if the material to be fed is frozen.
