Abstract: The present invention is directed to a thermally inhibited, subsequently enzymatically hydrolyzed, ungelatinized, granular starch or flour and the process of making such starch or flour. Such starch or flour is useful as an ingredient in food products, particularly fruit- or vegetable-based products.

Abstract: A process for producing a granulated material from a powder mixture containing at least two components, one of which is in crystal or crystalline form and at least one contains water of crystallization and/or is reactive, granulation is carried out in an inclined drum. Powder is fed in at one end and granulate removed at the other, after being transported inside the drum for a desired period while the drum is rocked in a way which largely eliminates shear forces. A quantity of liquid at least approximately equal to the quantity of water of crystallization present and sufficient for the formation of a superficially active solution adhesive is released inside the drum, where appropriate by partial reaction of the reactive component(s), after which the powder mixture components are granulated by surface adhesion.
Abstract: A method for continuously purifying a polysaccharide comprises the steps of continuously and simultaneously feeding an aqueous solution of a polysaccharide and a hydrophilic organic solvent which does not solubilize the polysaccharide, mixing these two kinds of liquids with a rotary turbine to precipitate the polysaccharide, cutting the precipitated polysaccharide with an interlocking cutter which comprises a fixed cutter and a rotary cutter, and continuously withdrawing a suspension of finely cut polysaccharide particles. The resulting polysaccharide is not in the form of strings, but in the form of fine particles and thus it is never adhered to an apparatus for purification and does not cause any retention within the apparatus. The particulate polysaccharides obtained by the method are easily separated from the resulting suspension and dehydrated.
Abstract: A method and apparatus for introducing a powdery substance to a particulate material contained within a rotary granulator. The powdery material is contained in a feeding hopper that is positioned above a nozzle that is in communication with a source of compressed air. The compressed air issues from the nozzle and draws from the supply funnel powdery material that is conveyed through a conduit that extends into the rotary granulator and is so oriented as to introduce the powdery material to the particulate material as it is being rotated. The compressed air can be introduced in the form of pulses by periodically interrupting the flow of air to thereby control the apportionment of the powdery substance.
