Abstract: The invention is a mixer-grinder for food processing. The unit is designed to provide both an ergonomically convenient position for the top of the hopper with respect to loading, for the discharge opening with respect to receiving the processed product and for the deepest point of the hopper with respect to cleaning. The apparatus includes a base; a hopper mounted on the base, the hopper being formed by a front wall, a rear wall and a curved bottom wall connecting the front wall and the rear wall; a trough formed in the bottom wall of the hopper; a discharge opening in the front wall at one end of the trough; a worm rotatably mounted in the trough for moving food toward the discharge opening; at least one paddle for mixing food in the hopper, the paddle being mounted on a rotatable shaft centrally positioned in the hopper; and a motor and transmission mounted on the base for driving the worm. The trough is preferably oriented such that a central axis thereof is upwardly inclined.
