  • Publication number: 20140190471
    Abstract: Embodiments of the present invention overcome the well-known recalcitrance of lignocellulosic biomass in an economically viable manner. A process and system are provided for the efficient fractionation of lignocellulosic biomass into cellulose, hemicellulose sugars, lignin, and acetic acid. The cellulose thus obtained is highly amorphous and can be readily converted into glucose using known methods. Fermentable hemicellulose sugars, low-molecular-weight lignin, and purified acetic acid are also major products of the process and system. The modest process conditions and low solvent/solid ratios of some embodiments of the invention imply relatively low capital and processing costs.

  • Patent number: 5925190
    Abstract: Inulins are pyrolyzed to di-D-fructose dianhydrides in good yield by heating at atmospheric pressure to a temperature sufficiently high to melt the inulin, or pyrolyzing in the presence of a hydroxy carboxylic acid such as citric acid, to melt temperatures of the mixture. The pyrolyzed inulins are used in foodstuffs to increase the relative proportions of bifido bacteria in the digestive tracts of humans and domesticated animals.

  • Patent number: 5865899
    Abstract: A process for refining a raw sugar, particularly raw sugar from the sugar cane sugar industry, characterized in that it comprises the steps of:(a) remelting of the raw sugar for obtaining a raw sugar syrup,(b) carbonatation or phosphatation of said raw sugar syrup, and(c) tangential microfiltration and/or tangential ultrafiltration of the raw sugar syrup, which has been subjected to carbonatation or phosphatation.The process is completed by the steps of:(d) decolorization of the sugar syrup resulting from step (c), and(e) crystallization and/or demineralization of the sugar syrup resulting from step (d).

  • Patent number: 5833757
    Abstract: A process which permits the facile conversion of green bananas to a sugar syrup uses a sequence of steps involving grinding the bananas, heating the bananas, treating the bananas with an alpha amylase to convert the starch granules into lower molecular weight molecules (liquefaction), changing conditions and treating the low molecular weight starch molecules and other substances in the liquefied fluid with the enzymes, amyloglucosidase, pectinase, cellulase, macerase, etc., filtering the resultant fluid to remove the solids, and, if necessary, evaporating the sugar solution to a suitable concentration. Use of elevated pH in each of the enzymatic conversion steps was found to greatly increase the glucose yield.

  • Patent number: 5759283
    Abstract: 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.

  • Patent number: 5409541
    Abstract: 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.

  • Patent number: 5338366
    Abstract: 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.
