The present invention relates to a method of separating sugars and sugar alcohols from each other. More particularly the present invention relates to the use of a weakly basic anion exchange resin in a chromatographic separation process. The advantage of the present invention compared with the prior art is that it is especially suitable for separating reducing sugars in acidic conditions as well as for example in weakly acidic conditions. The method using chromatographic separation comprises at least one step where a weakly basic anion exchange resin is used in a chromatographic column or in a part of a column.

A method for purifying a sucrose material already in a high purity liquid, crystalline or other form of sucrose, such as raw sugar, utilizing chromatography, or utilizing chromatography in connection with other methods of purification.

A continuous centrifuge (10) has a basket (30) with upper and lower basket portions (43, 44) separated by an intermediate slip portion (45). The lower basket portion (43) has an included angle of 40-50 DEG , to separate 'green' molasses from the sugar crystals, while the upper basket portion (44) has an included angle of 50-60 DEG , to separate washed molasses from the sugar crystals. The inner faces of the walls of the basket portions (43, 44) have radial drainage grooves (46), closed at their lower ends and open at their upper ends, to discharge the molasses.

A method for producing a work product including the steps of receiving a first fluid composed of a liquid, a target substance and at least one residual substance; passing the first fluid through a first work station for separating the residual substance from the first fluid to produce a secondary fluid substantially composed of the liquid and the target substance; and treating the secondary fluid to reduce the proportion of the liquid relative to the target substance in the secondary fluid to form the work product. An apparatus for producing a work product including an intake conduit adapted to receive a first fluid, composed substantially of water, a sugar substance and residual substances, from a rinsing system for raisins or the like; a first processing station adapted to remove the residual substances from the first fluid to form a second fluid, composed substantially of water and the sugar substance; and a second processing station adapted to treat the second fluid by reverse osmosis, nanofiltration, or the like to reduce the proportion of water relative to the sugar substance in the second fluid to form the work product.

A process for the continuous treatment of sugar cane filter cane mud separates and extracts components including fiber which can be used as an animal feed or a source of energy generation, lignin, beta-carotene, oil containing a high content of phytosterol, refined wax which is a resource of policosanol and which can also be used for many other established purposes, and resin which can be used an additive in asphalt mixtures and tire manufacturing or can be recycled back into the sugar milling process. The process is self contained, requiring the input only of fresh water and chemical additives to adjust pH and coloration.

The present invention provides a method for producing tagatose crystals from an aqueous system using no organic solvent. In this method, seed crystals of tagatose are added to a tagatose solution in which a tagatose purity of solid contents in the solution is at least 70% and a solid contents concentration in the solution is 60 to 98 mass %, and crystallization of tagatose is carried out by stirring and cooling the solution while keeping a degree of super saturation of tagatose at 1.25 or lower. It is preferred that the solution containing tagatose is a solution containing no organic solvent. It is further preferred that a part of massecuite for which the crystallization is completed is added to a mother liquor so as to produce the tagatose crystals semi-continuously or continuously. It is furthermore preferred that the tagatose crystals formed from the massecuite are separated by centrifugation or filtration and dried to obtain tagatose crystals.

The invention relates to the field of sugar production, in particular to a high-efficiency massecuite separator for sugar production. The technical problem to be solved by the present invention is to provide a method that can fully analyze sucrose crystals and waste honey through multi-layer and multi-stage separation and screening, and at the same time collect waste honey uniformly and avoid solidification of waste honey during collection, and provide noise reduction function and stable air pressure function High-efficiency massecuite separator for sugar production to prevent excessive noise and unstable air pressure during equipment operation. A high-efficiency massecuite separator for sugar production, including a support frame, a load-bearing base, a separation cylinder, a noise reduction component, a feeding pipe, an anti-solidification component, a first drip hopper, and a filter screen; the support frame is evenly fixed on the load-bearing seat bottom etc. The invention achieves the full analysis of sucrose crystals and waste honey through multi-layer and multi-stage separation and screening, and at the same time uniformly collects waste honey and avoids solidification of waste honey during collection, and provides noise reduction function and stable air pressure function to prevent excessive noise during equipment operation And the effect of air pressure instability.

The application relates to methods and systems for producing a sugar product. The method includes: receiving a first input in a control system representative of a pre-treatment sugar composition characteristic; receiving a second input in the control system representative of a post-treatment sugar product target specification; using the control system to determine at least one operating parameter for a centrifuge and operating the centrifuge in accordance with the at least one determined operating parameter, wherein the at least one determined operating parameter is determined from at least: the first input, the second input, and a correlation relating at least the first input and the second input to the at least one operating parameter; and treating the pre-treatment sugar composition in the centrifuge to produce a post-treatment sugar product with a characteristic that is at or nearer to the target specification than the characteristic of the pre-treatment sugar composition.

The present invention concerns a process that can be realised continuously for the preparation of anhydrous crystalline lactulose from commercial aqueous syrups that contain it, characterised in that the crystallisation and consequent separation of the high-purity lactulose with high yields from the syrup is triggered by mixing the ore pulp (or recycled ore pulp), obtained from a previous lactulose crystallisation phase, with the syrup itself.
