ABSTRACT:
Method and apparatus for converting grains, beans, and like materials into flour, as highly water absorbent starch. The material is introduced into the annular gap between a stationary outer truncated cone member and an inner rotating truncated cone member. The cone members are on a vertical axis, smaller ends uppermost, and have axial grooves on the opposed surfaces forming regions to grind the material introduced between the surfaces. The cone members taper inwardly toward the top and at about the upper half the opposed surfaces of the cone members diverge while at about the lower half the opposed surfaces are substantially parallel. The cone members are relatively adjustable in the axial direction, particularly to control the size of the gap between the lower portions thereof. In operation, material to be ground is introduced between the cone members at the top and is reduced to flour along the upper portions of the members while along the lower portions of the members friction developed on the ground material causes it to become heated. The starch granules are mechanically ruptured during the milling and are not more than partially cooked during the aforementioned heating.
If the material is substantially dry, the milling and heating will not release substantial amounts of steam but if the material is moist, the heating of the material will convert at least some of the water to steam, assisting in the disintegration of the starch granules of the grain and possibly causing some cooking thereof.
External heat may be supplied to the apparatus, electrically, or by gas.
