ABSTRACT:
A motor-driven grinding machine or unit has been provided to enable consumer-selected food items, such as nut kernels and grains to be quickly, uniformly and efficiently ground to a desired consistency in his or her presence. The machine has a chute with a motor-controlling lid that is adapted to receive selected food items and to feed them to a rotating auger shaft which extends into a processing housing. Food items are then advanced substantially radially outwardly between a pair of heads having opposed disc-like grinding surfaces, each of which has a set of inner, widely spaced-apart, relatively coarse teeth and an outer, relatively finer, closely spaced-apart set of teeth between which the food is advanced while the auger shaft rotates one of the heads and the food items are being ground and advanced between the surfaces strategically designed and positioned in a positive manner to reduce them to a desired uniform particle size. Slot portions between the teeth of the inner and outer sets provide outward flow paths for the food being ground that avoid clogging and excessive heat build-up, while assuring a full and uniform grinding and an outwardly advancing flow of the food between the pair of heads. The food as thus ground into a butter, meal or flour is moved peripherally forwardly into a front portion of the processing chamber, with a wiping action being effected by the rotating head for delivering the processed food through a down-spout or open portion in the housing. External means is provided for adjusting the axial position of the rotating head to control the operating relation between the teeth of the cooperating opposed grinding surfaces.
