    摘要: This invention relates to compositions and processes for improving the clarification of sugar juices and syrups in sugar mills. The process involves adding compositions directly to the juice and or syrup. The compositions provided in this invention are mixed intimately into the sugar juices or syrups, and allowed sufficient time to react with the sugar juices or syrups as well as with the any other chemicals added in the clarification processes so as to impart an improvement in the purity of the clarified juice or syrup obtained therefrom. Compositions include at least one particulate sulfur reagent containing at least one sulfur atom and at least three oxygen atoms, and one or more particulate solids selected from the group consisting of (A) a silica reagent, (B) a particulate phosphorous reagent containing at least one phosphorous atom and at least three oxygen atoms in the chemical formula, (C) a particulate carbonaceous reagent, (D) a particulate aluminum reagent containing at least one aluminum atom and at least three oxygen atoms in the chemical formula, (E) a particulate filter aid, (F) a polymer decolorant, (G) a particulate ammonium reagent having at least one ammonium group (NH4) in the chemical formula, and (H) a bleaching earth.

    摘要: A process for cold clarification of juice is described. A sugar cane or beet juice clarification process to clarify raw juice by means of aeration of fresh raw juice, addition of milk or lime, anionic and/or cationic flocculants, particularly together with a carbonating process, addition of phosphoric acid and then passing the juice through activated carbon bed is described. The process eliminates the need to heat the juice at any stage thus making it more cost effective, energy saving and gives better yield in terms of quality and quantity both. The recycling of defecated, carbonated and phosphated filtered juice and carbonated and phosphated mud that reduces the consumption of lime, CO2 and phosphoric acid up to some extent is described.

    摘要: 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.

    摘要: The invention relates to a method for obtaining white sugar from cane juice, characterized in that it involves: obtaining sugar colors of between 300 and 150 ICUMSA units, with a sulphite content no greater than 5 ppm and an ash content no greater than 0.2% in the case of white sugar and in the case of refined sugar with colors less than 40 UI, less than 5 ppm sulphites and less than 0.04% ash, using fewer chemical products and devices and comprising the formation of reducing sugars; as well as optimizing the production time, reducing deterioration, making the process and the chemical products more efficient and preventing SO2 contamination. The method is characterized in that it simplifies the traditional method of obtaining white sugar using elemental sulfur, eliminating prealkalinization and sulphiting and the respective machinery and equipment and reducing the number of chemical products, such as lime, phosphoric acid, sulfur and activated carbon, in order to aggregate only sodium metabisulphite optionally complemented with monosodium phosphate in juice with pH values of 4 to 6.6 prior to any process involving the clarification of juice, cane syrup or molten liquor.
