  • Patent number: 4416701
    Abstract: The method for the production of starch from grain or ground grain products by the wet process comprises a brief steeping of the raw material during which the morphological structures are not broken down by chemical or microbiological processes, and of a comminution of the steeped raw material in a high-pressure apparatus equipped with a splitter head. In this high-pressure apparatus, the steeped raw material is subjected to a pressure of at least 10 bar, fragmented under the action of high shear forces, and exposed to the atmosphere, thus causing the necessary structural breakdown between the starch grains and the protein. For shelled corn after the addition of process water, the shelled corn is fed to a heated pressure steeping apparatus. After a maximum of three hours at a pressure of 10 to 15 bar, the necessary moisture absorption is achieved. Excess water is fed to an evaporator. A pressure reducing apparatus at the output of the steeping apparatus produces a preliminary fragmentation of the corn grains.

  • Patent number: 4171383
    Abstract: There is disclosed a continuous process for refining whole grain wheat to obtain a wheat starch fraction and an animal feed product, the process comprising cleaning whole wheat kernels to separate extraneous matter, wet milling the cleaned whole wheat kernels to provide a mill starch slurry, separating fiber (bran) tailings from the mill starch slurry, washing and dewatering the fiber (bran) tailings, separating the mill starch slurry into a starch-rich fraction and a protein-rich fraction, concentrating and dewatering the protein-rich fraction, combining the wheat cleanings, the dewatered fiber (bran) tailings and the dewatered protein-rich fraction with an aqueous concentrate resulting from the partial evaporation of the filtrates obtained during the dewatering of the protein-rich fraction to form a wet animal feed product, and drying the feed product.

  • Patent number: 4154623
    Abstract: A process of preparing a starch hydrolysate from wheat, barley or rye comprising the steps of contacting kernels of wheat, barley or rye with an aqueous solution to hydrate and soften the kernels, gently wet-milling the hydrated and softened kernels, separating fibres and pentosans attached thereto as well as germs and gluten from the wet-milled product to form a starch-containing slurry essentially free of insoluble pentosans, carefully washing the fraction to form a refined, starch-containing product, hydrolysing the refined product to form a starch hydrolysate and finally refining the hydrolysate.

  • Patent number: 4106487
    Abstract: Corn is steeped in a process in which corn is continuously added at the top of a cylinder of a height of at least 1.5 to 2.5 times its diameter, water is continuously circulated upward through downflowing corn. This water, comprising a combination of steep water moving with steeped corn together with fresh mill and water containing corn solubles, is continuously withdrawn from the top of the tank. A conical bottom of the tank of specific dimensions aids in the continuous down-flow of corn.

  • Patent number: 4086135
    Abstract: A process for steeping grain wherein the steepwater is inoculated with an inoculum containing a microorganism of the genus Lactobacillus at or near the beginning of the steeping process. The process reduces the steeping time and increases the content of lactic acid in the steepwater. The process also reduces the amount of sulfur dioxide needed in the steeping process.

  • Patent number: 4042414
    Abstract: Waxy, small granule starch of high spreadability, and waxy, large granule starch which is capable of forming an exceptionally clear and bright paste, are simultaneously produced by steeping waxy barley grain for a period of at least 12 hours in an aqueous solution containing sulfur dioxide at a temperature of 45.degree.-55.degree. C so as to swell the grain and extract soluble protein contained within said grain, water washing and milling said steeped grain, separating the starch from fibers and protein, suspending said starch in water to form a suspension containing less than 15% wt solids, permitting larger granules to settle for a period of at least 2 hours and recovering a larger granule fraction, said larger granules being characterized by an average particle size of greater than 10.mu., and breaking the remaining suspension and recovering therefrom a smaller granule fraction, said small granules being characterized by an average particle size of from 2.5 to 10.mu..
