Efficient control of sugar processing and refining is vital for maintaining product quality while optimizing resource use. The role of real-time colorimeters in sugar process control is evaluated, emphasizing their validity for process control compared to ICUMSA® laboratory methods for solution colour determination.
The efficiency of the evaporation plant contributes significantly to determine the exhaust steam demand and energy efficiency of the plant. Exhaust steam consumption in Tucumán can be improved by modifying the evaporation operation scheme, which generally requires investments, to a greater or lesser extent depending on the modifications made.
Development of innovative technology based on mechanical vapour recompression (MVR) for sugarcane processing is explained. The reuse of thermal waste heat using a compressor allows high heat economy and eliminates the need for external heat generation and rejection units such as boilers, turbines, cooling towers and condensers.
The cane shredder is one of the most maintenance-intensive and costly machines in the preparation and milling process, requiring hammer replacements every 15-25 days, taking approximately 2-4 hours for that work and causing up to 20 annual stoppages.
A persistent issue faced during raw sugar manufacturing is the presence of microbial contaminants such as bacteria (e.g., Leuconostoc spp.) and their associated exopolysaccharides (EPS). Many of these microorganisms consume sucrose directly, decreasing product value, while also generating EPS that may elevate viscosities and introduce operational challenges and associated costs.
Crystal elongation is unwanted since it reduces crystallization rates and leads to higher molasses production with higher purities, centrifugation problems, and higher sucrose losses. Sucrose crystal elongation usually occurs because growth in certain directions is inhibited by an impurity rather than accelerated.
In many sugarcane-producing regions, payment systems often fail to account for extraneous matter (EM), such as leaves and soil, which are harvested along with the sugarcane stalks. This oversight fails to incentivize growers to deliver higher-quality cane and negatively impacts factory efficiency.
Sugar mills in Tucumán, Argentina, continue using indirect methods to assess sugarcane quality for payment purposes. This study aimed to implement and optimize a more accessible and economical direct evaluation method.
Dextranase (endo 1→6-a-glucan hydrolase) enzyme is applied in sugarcane factories to hydrolyse dextran (a-1→6-D-glucan) into smaller, more manageable molecules, which can improve crystallization rates, reduce crystal elongation problems, and prevent dextran penalties in the raw sugar.
The Andhra Sugars Limited (India) operates three cane sugar plants, producing direct plantation-white sugar. With innovation, good quality sugar meeting EC-2 specifications is being produced at the three plantation-white cane sugar plants without the use of a backend refinery or sophisticated filtration equipment.
