Patent number: 7815876Abstract: The reactor pump for hydrolytic splitting of cellulose is configured to pump cellulose, under high pressure, with low availability of sugar into a reactor. The reactor has an upstream transition segment connected to a downstream reaction chamber. The transition segment has an inlet that is smaller than the outlet. The inner walls taper outward. The chamber has an inlet that is larger than the discharge outlet. The inner walls taper inward. The transition segment outlet has an area that is substantially the same as the area of the chamber inlet. Back pressure in the chamber forms a cellulose plug within the inlet of the transition segment. The plug stops cellulose from escaping out the inlet. High pressure pumping forms a cellulose plug within the discharge outlet of the chamber. The plug slows downstream movement of the cooking cellulose giving the cellulose time to cook. Cooking cellulose begins to breakdown under heat and the injection of acid, if required.Type: GrantFiled: October 31, 2007Date of Patent: October 19, 2010Inventor: David A. Olson

Patent number: 7815741Abstract: A reactor for hydrolytic splitting of cellulose under high pressure and heat has an inlet and outlet each with a cross-sectional area smaller than the cross-sectional area of the reactor. The pressure and heat in the reactor forms a cellulose plug within the inlet and the outlet. The inlet plug stops cellulose from escaping out the inlet. Cellulose begins to breakdown under heat, pressure, and if required an acid or a lubricant. The outlet plug slows downstream movement of cooking cellulose. Cellulose may be pre-treated by the addition of water, a weak acid, a lubricant, or a combination of the foregoing. The outer surface of the plug cooks faster than the inner core of the plug, becomes a liquefied slurry, and slides faster towards the outlet than the inner core.Type: GrantFiled: January 25, 2008Date of Patent: October 19, 2010Inventor: David A.

Patent number: 5468300Abstract: Refined sugar is produced directly from sugarcane without using conventional refining processes. Clarification of extracted cane juice is obtained either by ultra-centrifugation or ultra-filtration, and removal of certain compounds responsible for adverse color quality and viscosity is effected through a set of packed columns filled with an absorbent for these compounds. After evaporation and crystallization, refined cane sugar is produced.Type: GrantFiled: April 7, 1994Date of Patent: November 21, 1995Assignee: International Food Processing IncorporatedInventor: Jean-Pierre Monclin

Patent number: 5451262Abstract: A syrup of natural carob sugars having 55-75% sucrose, 7-15% fructose, 7-16% glucose, 0.5-3% other sugars, 4-14% cyclitols and 0.5-2% organic and inorganic impurities. Sugars are extracted from carob pulp and the juice thus obtained is subjected to chromatographic separation to separate the sugars from the non-sugars. The product obtained may be used in applications similar to those of other sugars.Type: GrantFiled: March 23, 1994Date of Patent: September 19, 1995Assignee: Compania General Del Algarrobo De Espana S.A.Inventor: Carlos S. Diaz

Patent number: 5409541Abstract: A counterflow single-screw extractor includes a screw conveyor having a helical scroll formed from arcuate flight sections each having a plurality of elongated slots extending away from the direction of screw rotation and permitting the flow of effluent through the product and the flights in a manner controlled by the size, number, and orientation of the slots. The slots permit efficient extraction using relatively little extraction medium and at the same time permit a single-screw extractor to be used without having to periodically reverse the direction of screw rotation to unclog the slots and by the pitch of the screw conveyor. The inventive arrangement permits the use of a multi-section extractor employing different extraction media and/or different extraction media wash rates in different sections of the extractor.Type: GrantFiled: November 30, 1993Date of Patent: April 25, 1995Assignee: dxResources CorporationInventor: David R. Walker

Patent number: 5366558Abstract: Two stage hydrolysis of lignocellulosic material, conditions during the first stage being such as to hydrolyze or depolymerize the hemicellulosic component without substantial degradation of resulting monosaccharides, conditions during the second stage being such as to hydrolyze the cellulose to glucose without substantial degradation of the glucose. The solids left after first stage hydrolysis are disintegrated mechanically thereby greatly facilitating second stage hydrolysis. Hydrolysis in both stages is preferably accomplished by the use of nitric acid. The pH retention time and temperature in both stages are selected to maximize production of the desired monosaccharide or monosaccharides.Type: GrantFiled: June 8, 1993Date of Patent: November 22, 1994Inventor: David L. Brink

Patent number: 5358571Abstract: Extraction processes for the recovery of sugar from sugar cane can be improved by the incorporation of a fiber depither between one or more of the extraction mills. The cane fiber from an extraction mill is fed to a fiber depither where the cane fibers are macerated to break sugar containing cells. The sugar is removed in a liquid stream and the cane fibers in a solids stream. The cane fibers are preferably fed to a subsequent extraction mill. The liquid stream is preferably flowed countercurrent to the flow of cane fiber to the first extraction mill. From the first extraction mill the liquid stream is sent to sugar recovery.Type: GrantFiled: May 27, 1993Date of Patent: October 25, 1994Inventors: Eduardo J. Villavicencio, Eduardo G. Villavicencio Charpentier

Patent number: 5320035Abstract: An improved sugar cane juice extractor has removable crushing rollers. The juice extractor preferably includes a housing with a juice extracting compartment and a closure for accessing the compartment. The closure is preferably a clear plate which permits viewing of the compartment during operation and, when removed, allows access to the compartment for removal of the crushing rollers and cleaning of the rollers and the compartment. A safety switch can be provided to prevent rotation of the rollers when the closure is displaced. A guide into the compartment is preferably provided to direct the sugar cane and any flavorings into the crushing rollers. A waste channel is provided for the exit of crushed cane pulp.Type: GrantFiled: November 27, 1991Date of Patent: June 14, 1994Assignee: Salus CorporationInventors: Alfredo J. Sanchez, Rafael E. Sanchez, Jr., Charles J. Stemmann, Jr.
