  • Patent number: 4613086
    Abstract: A base frame supports a hopper for receiving grain to be ground and made into bread. An inverted cone-shaped grinding head on the shaft is supported at the bottom of the hopper and cooperates with a base member having a recess corresponding in shape to the grinder. The cone-shaped grinding head is spaced from the base to form a grinding area and grinding is accomplished by upright surface grooves in the base member and grinding teeth on the grinding head. The grinding head has an inlet passageway leading to the grinding area and the base member has outlet means at the top of the grinding area to discharge ground grain which is forced upwardly by centrifugal force as well as the augering action of the grinding surface. The shaft supports a mixing arm at the bottom thereof having an angle bend which provides simultaneous mixing and kneading of ingredients into bread dough. The bread dough making apparatus is combined with apparatus for driving food processing attachments such as a blender and meat grinder.
