Abstract: A process for the production of starch from cereals includes the steps (a) subjecting dry-ground dehusked grains to enzyme treatment, (b) homogenizing the treated product (optional), (c) extracting starch from the homogenized product, leaving the fibre, (d) concentrating the starch to yield a crude starch fraction and process water, (e) separating proteins from the crude starch and (f) separating the crude starch into primary and secondary starch fractions. The process assures that solubles will be maximized so that drying can be accomplished primarily by evaporators rather than by other types of dryers.
Abstract: Individual coolant passages in the airfoil portion of a liquid-cooled turbine bucket are each provided with a plurality of spanning elements spaced along, affixed in and extending across each passage whereby the main flow of liquid coolant moving in each such individual passage during turbine operation under the influence of centrifugal force is broken up. Each spanning element has one end thereof approximately centered in the region of the passage at that station therealong, which will be the most rearwardly disposed during rotation of the bucket in operation. In the embodiment described the spanning elements are cylindrical pins of circular cross-section disposed generally parallel to each other.
