Patent number: 4435429Abstract: A process for treating cereal grains and particularly oats, to separate the endosperm from the remainder of the kernel without dry milling. The grains are soaked in an aqueous medium having a pH of 3.0-7.0 at a temperature in the range 40.degree.-70.degree. C. for sufficient time to absorb at least an equal weight of the liquid medium. The conditions are such that the endosperm portion of the grain liquefies, as opposed to softens. The grain may be crushed in a variety of ways to split the husk and release the liquid endosperm contents which are then dispersed in water. The endosperm solids can be recovered from dispersion, following a screening step to separate the husks by drying to yield a substantially white, lower fiber whole endosperm flour product. Alternatively, the dispersion may be sedimented and/or centrifuged to produce a wet solids fraction and a soluble fraction, each of which can be subsequently recovered in dry form.Type: GrantFiled: February 16, 1982Date of Patent: March 6, 1984Assignee: Canadian Patents and Development LimitedInventors: Vernon D. Burrows, Royce G. Fulcher, David Paton

Patent number: 4329371Abstract: Methods and apparatus for processing grain to provide meal, grit, flour and masa products suitable for human consumption and by-products suitable for use as animal feed and industrial products. The methods includes forming a slurry of the grain with water and processing the slurry through dehusking, germ detaching, grinding and sifting stages while maintaining the grain at a relatively high moisture content. Partially different methods are employed depending on whether the processed grain is sorghum, wheat or corn. The processing apparatus includes a dehusking unit having a plurality of pump stages to remove the husks from the grain kernels without cracking a substantial portion of the kernels. A fluidized bed dryer is utilized to remove excess water and to surface dry the kernels and husks. For sorghum grains a centrifugal impact germ detacher is utilized to break up the dehusked kernel and separate the germ and oil from the endosperm.Type: GrantFiled: November 20, 1978Date of Patent: May 11, 1982Assignee: Seven-H CorporationInventor: Edwin R. Hart

Patent number: 4325976Abstract: A reformed rice product is made by extruding a dough through a low-pressure, pasta-type extruder to form simulated rice grains which are then dried at a temperature of up to 150.degree. C. to a final moisture content not exceeding 15% of the product. The dough is made by adding water to a dry composition comprising a mixture of pregelatinized and ungelatinized flour, sodium chloride and fat in powder form.Type: GrantFiled: March 18, 1980Date of Patent: April 20, 1982Assignee: Thomas J. Lipton, Inc.Inventors: Alastair D. Harrow, John W. Martin

Patent number: 4234614Abstract: A method for processing grain, e.g. corn, to provide a flour or grit product suitable for human consumption and by-products suitable for use as animal feed and industrial products which includes forming a slurry of the grain with water and passing the slurry through a plurality of pump stages having turbine pumps equipped with turbine pump impellers to remove the husks from the grain kernels without cracking a substantial portion of the kernels. The slurry is then passed through a centrifuge to remove excess water, surface dried and passed through an aspirator to separate the husks from the grain kernels. The dehusked kernels are sent through a centrifugal impact cracker to break up the kernel and separate th germ and oil from the endosperm. The broken kernel pieces are then milled to produce flour.Type: GrantFiled: November 20, 1978Date of Patent: November 18, 1980Assignee: Seven-H CorporationInventor: Edwin R. Hart

Patent number: 4208260Abstract: A process for the separation of comminuted proteinaceous material from an admixture thereof with solvent is disclosed. An admixture of the material and the solvent is subjected to a high voltage electric field between an anode and a cathode, thereby depositing at least part of the material on at least the anode. The solvent is an aliphatic hydrocarbon containing from 5 to 8 carbon atoms or a normally liquid chlorofluorocarbon containing 1 or 2 carbon atoms. The proteinaceous material may be wheat, rye, barley, triticale, rice, peas, beans, soya beans, sesame seeds, peanuts, sunflower seeds, whey powder, corn, rapeseed, sorghum, flax and buckwheat. In an embodiment the fraction is in the form of a dispersion, e.g. fines, in the solvent.Type: GrantFiled: May 3, 1979Date of Patent: June 17, 1980Assignee: Du Pont of Canada, LimitedInventor: Richard W.

An admixture of the fraction and the solvent is subjected to a high voltage electric field between an anode and a cathode, thereby depositing at least part of the comminuted oat fraction on at least the anode. The solvent is either an aliphatic hydrocarbon containing from 5 to 8 carbon atoms or a normally liquid chlorofluorocarbon containing 1 or 2 carbon atoms. In a preferred embodiment the fraction is a fraction of high protein content and the deposit is only on the anode.

Patent number: 3974298Abstract: Grain, (or a milling intermediate, e.g. semolina) is heated at a temperature of 100.degree. to 140.degree.C (or 100.degree.-200.degree.C for semolina) for a period inversely related to temperature and not less than 1 hour at 100.degree.C, so as to improve the quality of cake flour produced by milling (or further milling). The time of heating t (in minutes) is preferably related to the temperature T (in .degree.C) by the equation t = a' - b'T + c'T.sup.2 where for wheat a'= 2188, b'= 31.535 and c' = 0.11438 and for semolina a' = 408, b' = 4.252 and c' - 0.1121. The need for chlorination of the flour produced is thus avoided.Type: GrantFiled: September 5, 1974Date of Patent: August 10, 1976Assignee: Flour Milling and Baking Research AssociationInventors: Stanley Peter Cauvain, Donald Gordon Hodge, David Donald Muir, Norman James Harold Dodds
