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.

Claims6

Dependent claims

A bread dough making machine comprising:

(a) having inverted cone-shaped member having upper end and a lower ends;
(b) a base member having a tapered recess with a defining wall receiving said cone-shaped member, the wall of said recess being shaped to provide a grinding area between the wall and said cone-shaped member with said grinding area being progressively less toward the upper end of said cone-shaped member, said grinding area having outlet means, at least one of said base member and cone-shaped member having a grinding surface and at least one of said base member and cone shaped member being rotatable relative to the other of said base member and cone shaped member for reducing grain to a smaller particulate form, said grinding area having a closed bottom end at the lower end of said cone-shaped member, and said cone-shaped member forcing ground grain upwardly and discharging it from the upper end of said cone-shaped member,
(c) power drive means for rotatably driving said cone-shaped member;
(d) means arranged to feed grain to be ground into said grinding area;
and a mixing arm on said power drive means arranged to mix ground grain from said grinding means with other bread ingredients and simultaneously to knead the ingredients into bread dough.

2 more elements

A food processing machine comprising:

(a) a base frame;
(b) a vertical hopper supported on said base frame and having an upper infeed end and a lower outfeed end;
(c) grinding means supported on said base frame under the outfeed end of said hopper, said grinding means including an inverted cone-shaped grinding member having an upper end, and a base member having a recess with a defining wall receiving said cone-shaped member, said defining wall being spaced from said cone-shaped member but in close relation to said cone-shaped member to form a grinding area between said defining wall and said cone-shaped member, said grinding area being tapered progressively to a narrowed dimension toward the upper end of said grinding member, at least one of said base member and cone-shaped member having a grinding surface and at least one of said base member and grinding member being rotatable relative to the other of said base member and grinding member for reducing grain to a smaller particle form, said grinding means further having an upper end and a lower end and including an infeed portion arranged to receive grain from said hopper and an outfeed portion arranged to discharge ground grain outwardly, said grinding area having a closed bottom end at the lower end of said grinding means, and said grinding means forcing ground grain upwardly and discharging it from the upper end of said grinding means;
(d) power drive means, on said base frame for rotatably driving said grinding means;
(e) a passageway area encircling said grinding means and having an upper receiving end communicating with said outfeed portion of said grinding means, said passageway area conveying ground material downwardly by gravity and having a bottom discharge end;
(f) a mixing area disposed vertically below the discharge end of said passageway area and arranged to receive a mixing bowl for deposit of ground grain;
and
(g) a mixing arm on said power drive means and arranged to mix the ground grain which falls by gravity from said passageway area into said mixing area with other ingredients.
