A machine for dispensing dry and moist materials including those which are self-adhering and/or compactible or which tend to agglomerate comprising a material dispensing chute formed at its sides by horizontally reciprocating, expanded metal grid plates which engage and separate material from adjacent material pressing thereagainst for passage through the grids of the plates and metered depositation onto articles or products passing therebeneath. The grid plates have horizontally spaced, downwardly converging upper portions forming a V where the majority of material is separated and horizontally spaced, parallel lower portions forming a narrow transverse width channel which prevents material from loading up between the grid plates in the V, such giving the chute a generally Y-shape in transverse cross-section. Depending on the material being dispensed, the grid plates may be formed from either flat or raised expanded metal grid material preferably having a diamond grid pattern that enhances material separation through a funneling or wedging effect. The grid plates are desirably reciprocated in respective top and bottom tracks by eccentrics in a direction opposite each other for more uniform discharge of material. Either grid plate may be fixed and/or replaced by a solid or part solid/part grid plate, the latter providing a narrower width discharge pattern. Also provided is a power drive motor mount which permits quick and easy removal of the motor to allow cleaning of the machine without subjecting the motor to the cleaning environment.
