Abstract: The process comprises the steps of: distributing a sugarcane load, with mineral and vegetable impurities, on a conveyor belt (12), forming thereon a sugarcane and impurity mattress; submitting the mattress to a dosing and spreading operation, forming a thin and dispersed curtain in gravitational displacement in a first chamber portion (15); submitting the sugarcane and impurity curtain to a transversal and ascending forced air flow, displacing the impurities outwards from the curtain to the interior of a first collecting compartment (21) and of a second and a third chamber portion (22 and 27); deflecting the fraction of forced air flow, received in the third chamber portion (27), obtusely in a plurality of adjustable “Persian blinds” (28), decompressing the air flow; discharging the clean sugarcane load and the impurities through a clean sugarcane lower outlet (19) and through impurity outlets (21a, 23a and 26a).

Abstract: A process is proposed for recovery of water in the sugar cane processing in production mills of sugar and alcohol or only alcohol (ethanol). In the process, the thermal energy available in the exhausted steam from the electric energy generation turbines is transferred to the different mixed juice processing phases, with the reuse of the exhausted steam condensates in the boilers and of the other condensates, after using thermal energy, for imbibition, in the juice extraction phase, for cooling in the process, after passing through cooling towers, for other industrial uses and for possible treatment or use in the irrigation out of the productive system in the mill.

Abstract: The process includes phases of: (I) treatment, initial clarification and concentration (TC) of sugar cane juice, with 13-18° Brix, through treatment, decantation and concentration of the juice, for a syrup concentration of 60-65° Brix; (II) initial clarification and decoloration (CD) of the syrup, with removal of insoluble materials and turbidity, through: (a) flotation of the syrup, (b) filtration of the flotated syrup, (c) demineralization of the filtrated syrup, (d) decoloration of the syrup in a second ionic change column (C2), containing an anionic resin bed, and (e) polish of the syrup in a third ionic change column (C3) containing an anionic resin bed; (III) cooking and crystallization (CC) of the syrup in sugar crystals and their centrifugation for separation of the remaining runoff syrup; and (IV) drying and storage (DS) of the granulated refined sugar.

Abstract: The invention relates to a process for producing an organo-mineral fertilizer from vinasse, filter cake and generally boiler ashes, as byproducts of the sugar and/or alcohol manufacture and, optionally, complemented with fertilizer sources composed of macronutrients (primary and secondary) and micronutrients. The process comprises, in a preferred form of the invention, the steps of: concentrating the vinasse until about 65% of solids (p/p); mixing and dissolving the fertilizer elements in the concentrated vinasse; mixing and drying the filter cake and ashes in a hot gas stream obtained by burning bagasse or fine straw; impregnating this dry mixture with the concentrated vinasse mixture and the added fertilizer agents; and, finally, drying and granulating the final formulated mixture. The end product is a granular solid containing N, P, K, Ca, S, Mg and micronutrients, according to the previously programmed formulation.

Abstract: “PROCESS OF DIRECT REFINED SUGAR PRODUCTION”, being a process that uses the sugar syrup as raw material to produce granulated refined sugar, characterized by changing the conventional process of non-refinated sugar production by the addition of three modules designated as clarification, decoloration and new cooking process that, together with the conventional plant, allow the production of refined sugar, and there is not necessity of crystallized sugar dissolution, followed by its recrystallization.
