Date Jan. 11, 1996The invention relates to a process for fractioning vinasse, in which process the pH value of the vinasse is lowered by adding acid, and the formed precipitate is separated in order to obtain an inorganic fraction, whereupon an organic fraction remains. The invention also relates to the products obtained. The inorganic fraction mainly contains potassium salt, and it is useful for example as a fertilizer. The organic fraction mainly contains organic acids, and it is useful for example as an additive in animal feed and in producing silage.

A sugar refining process uses carbon dioxide obtained from a module containing a plurality of gas-permeable polymeric membranes. Flue gas from a boiler is scrubbed, and then passed through the gas-separation module. The output of the module contains an enhanced concentration of carbon dioxide, in the range of about 20% by volume. The carbon dioxide enhanced gas is then directed into a reactor in which raw sugar is exposed to carbon dioxide to cause carbonation, an essential step in the decolorization of the raw sugar. The same boiler used to produce the carbon dioxide is also used to produce steam which drives the reaction. The present invention provides carbon dioxide for carbonation in a highly efficient manner, as the gas separation membrane has no moving parts and requires little maintenance. The invention is especially suited for retrofitting existing sugar refining plants, to improve their efficiency, at a relatively small cost.

The invention relates to an improved nanofiltration process for separating and recovering components, such as sugars and sugar alcohols from multicomponent mixtures. The process of the invention is characterized by collecting the nanofiltration retentate/permeate in several fractions with different purity, optional recycling of at least one of the collected nanofiltration retentate/permeate fractions to the nanofiltration and recovering the desired component from the nanofiltration permeate/retentate fractions by different methods. In one embodiment of the invention, the process comprises a combination of nanofiltration and chromatography.

A process system that uses a reduced amount of lime or other base to clarify or purify juice obtained from plant material such as sugar cane, sugar beets, or sweet sorghum. Specifically, apparatus and methods to reduce volatile materials in juice providing a product that has an increased pH requiring the use of less lime or other base to achieve the desired pH values for clarification or purification.

The invention concerns an improved method for purification of raw sugar beet juice, which is obtained by extraction from sugar beets, and to devices for purification of raw sugar beet juice. The invention further concerns a method for producing sucrose syrup or sucrose from raw sugar beet raw.

Conventionally, sugarcane processing avoids leaving residual sucrose in the bagasse, since the bagasse will be burned and the value of the sucrose would be lost. However, when coupled with a Green Power+® process to extract hemicelluloses, sucrose may also be extracted and recovered from the bagasse. In some variations, a process includes mechanically treating a feedstock to generate a sucrose-rich stream and lignocellulosic material that intentionally retains a significant amount of the initial sucrose in the feedstock; extracting the lignocellulosic material with steam and/or hot water to produce cellulose-rich solids and an extract liquor containing hemicellulosic oligomers and sucrose; and then hydrolyzing the hemicellulosic oligomers into a hemicellulose sugar stream. Each of the sucrose-rich stream and the hemicellulose sugar stream (containing the starting residual sucrose) may be recovered or further processed (e.g., fermented to ethanol). Similar processes are possible with energy cane, sugar beets, and energy beets.

The invention relates to an industrially useful process for the recovery of sucrose and/or non-sucrose components. The process comprises (i) providing a solution of sugar beet and/or sugar cane origin selected from molasses, sugar juices and liquors, wherein said sugar juices are non-nanofiltered during the process; (ii) subjecting said solution to electrodialysis for removing therefrom inorganic and organic anions and cations and organic acids; (iii) subjecting the electrodialyzed solution to a chromatographic separation for obtaining sucrose and non-sucrose components in separate fractions; and (iv) recovering a product selected from sucrose and non-sucrose components from at least one of said fractions. The invention also relates to the use of electrodialysis for improving the efficiency of chromatographic separation in the industrial recovery of sucrose and/or non-sucrose components.

The invention discloses an efficient separation method for sugar in sugar beet sugar production. The method comprises the following specific steps: molasses pretreatment, chromatographic separation, concentration and crystallization, and sugar content detection. The method comprises the following steps: 1) molasses pretreatment: heating molasses to 70-90 DEG C, diluting the molasses to 50-70% withwashing water, removing suspended impurities from the diluted molasses aqueous solution, and filtering to obtain clean juice free of suspended impurities, calcium, magnesium and the like; 2) chromatographic separation: sequentially simulating a moving bed, and obtaining two items through separation, wherein an extraction phase contains sucrose with a high recovery rate, and a residual liquid phase contains non-sugar with a high recovery rate; 3) concentration and crystallization: evaporating and concentrating to 65-75% brix, storing, performing four-stage sugar boiling and crystallization toobtain qualified white granulated sugar (the color value is less than or equal to 35IU), and concentrating and crystallizing an extract phase to obtain purified syrup of which the sucrose purity can reach 89-95%, the brix is 30-350Bx and the sugar recovery rate is 88-95%; and 4) sugar content detection: detecting the purity of sucrose by using high performance liquid chromatography. The method isreasonable in design, environmentally friendly in use and high in economic benefit, and high-purity components can be obtained.

An apparatus for the continuous process of raw mixed sugar juice clarification by means of the settlement of insoluble particles and juice precipitate in a cylindrical clarifier tank that permits non-turbulent vertical subsidation and short retention time of the sugar juice in a relatively large, non-turbulent settling sector of the contents of the cylindrical clarifier tank which is maintained by the continuous rotary advancement of the raw mixed sugar juice entry and clear sugar juice and precipitate extraction station arm that rotates within and around the center of the annular shaped cylindrical clarifier tank. The rotating arm has three internal radial compartments which provide for the introduction of raw mixed sugar juice and the extraction of clear sugar juice and precipitate, in and out of the annular clarifier tank in the immediate vicinity of the respective leading and trailing faces of the rotating arm, through adjustable slots on the leading and trailing faces of the arm.
