| Due to the growing demand for Brazilian VHP (Very High Polarization) and VVHP (Very Very High Polarization) raw sugars, mainly by overseas markets, there is a need for better techniques to provide such high quality products, better use of the installed capabilities currently in sugarcane factories, good factory thermal balance, and incremental improvements in industrial efficiency. Technical-economical solutions to address these needs are currently considered a major priority by research centers, sugar businesses, and Brazilian sugar-technologists. This paper aims to discuss the alternative engineering processes that are currently being applied in Brazilian Sugar Mills for VHP or VVHP production, which range from the arrival of sugarcane at the factory to the sugar drying process. This also includes techniques that allow all the products specifications to be met, including market requirements and the effects of variations in the quality of raw material. Also included are the influences of increased mechanization in sugarcane harvesting and incremental restrictions in sugarcane pre-harvest burning, as well as the problems and solutions related to final product storage. Finally, some results from recent harvests will be presented that show a sugar factory yield of above 80% even when two massecuite systems were utilized, and up to 10% increments in plant capacity when VHP production capacity was compared to the white sugar production. |
