Patent number: 5759283Abstract: An efficient method for manufacturing a purified juice product from sugar beets. Untreated beet juice is initially prelimed using lime and CaCO.sub.3 to produce a prelimed juice product. Instead of subjecting the prelimed product to main liming and dual carbonation stages, the product is delivered to a porous filtration membrane which allows sugar molecules to pass therethrough which preventing the passage of solid matter and dissolved impurities. Optimum results are achieved if the prelimed product flows across the membrane from end to end. The membrane permeate is thereafter combined with CO.sub.2(g) in a single carbonation stage to remove dissolved lime. This step generates a purified juice product which can be processed to manufacture pure crystalline sugar. The membrane retentate can be combined with water and refiltered to collect residual sugar materials. The foregoing process uses less energy and raw materials (e.g. lime) compared with conventional methods.Type: GrantFiled: May 14, 1996Date of Patent: June 2, 1998Assignee: The Western Sugar CompanyInventors: Eric P.

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.

Patent number: 5338366Abstract: Biomass, such as bagasse, is pre-hydrolyzed, to ultimately effect hydrolysis of hemicellulose to sugars. Biomass is mixed with a mineral acid solution to form a slurry having a consistency of about 8 to 12% so that the acid solution properly wets the biomass. Then the slurry is dewatered to about 35 to 50% consistency, and is heated to reaction temperature (e. g. about 320.degree. F.) by direct contact with steam in the vapor phase of a vertical pressurized reactor, having a pressure of about 40 psig. A fluffer is preferably provided in the top of the reaction vessel. After a reaction time of about 30 minutes, the biomass is diluted and cold blown out of the bottom of the reactor. Pressate from the dewatering has acid added to it and is heated by indirect heat exchange with a sugar solution obtained by washing of the biomass discharged from the reactor, and is then mixed with the biomass as the acid solution.Type: GrantFiled: January 4, 1993Date of Patent: August 16, 1994Assignee: Kamyr, Inc.Inventors: Todd S.
