A modern energy efficient sugar complex on 26% steam consumption – concept to commissioning
Last Updated: junio 19, 2025A modern sugar complex with a crushing capacity of 7500 t cane/d with a steam demand of 26% on cane and steam consumption (260 kg of steam/t of cane) to save bagasse. The purpose of bagasse saving was to utilize it for paper production.
An improved electric drive for sugarcane preparation machines
Last Updated: junio 19, 2025An improved electric drive is presented for coupled motor-run sugarcane preparation machines in the sugar industry. The conventional slip ring induction motor (SRIM) drive has shortcomings of huge slip power loss, high drop in the rated speed, less flexibility for realizing optimum knife/hammer tip speed, low power factor, and unequal load sharing.
An innovative way for steam economy and capacity expansion by integrating an MVR in an evaporation scheme
Last Updated: junio 19, 2025The sugar industry is an energy-intensive industry, with significant energy costs associated with the evaporation process. A novel energy saving scheme is introduced by integrating mechanical vapour recompression (MVR) technology into the evaporation stages of sugar production as the syrup concentrator.
Assessing the impact of evaporator station configuration on the feasibility of greenfield cane factory projects
Last Updated: julio 6, 2025The greenfield cane sugar factories built in the last two decades have largely focused on reducing exhaust steam consumption for the process to maximise either power generation for export/allied industries or bagasse savings for value added co-products.
Automatic handling of soft cane in the factory
Last Updated: junio 19, 2025This study was undertaken to address concerns that many cane varieties in the development pipeline in Australia have fibre quality classified as soft, with some soft enough to cause processing problems in the factory. Where soft canes have been approved for production, the factory has to have a strategy to process them.
Bagasse drying using boiler flue gas – waste heat recovery
Last Updated: junio 19, 2025The concept of drying bagasse with flue gas was introduced to improve the utilization of waste heat from sugar mill boilers, thereby improving boiler performance and fuel saving. A demonstration project of a flash-drying system with a 10.0 t/h capacity was tested in 2009 in India, where bagasse was dried in a co-current flow in the flash tube with part flue gas from a 70 t/h boiler and then passing through cyclonic separators.
Batch pan automation: energy savings and sugar quality improvements
Last Updated: julio 6, 2025This paper explores the benefits of a properly automated batch pan operation. By avoiding water additions to the pans, the steam consumption is reduced while the sugar crystal quality improves in terms of colour.
Efficiency optimization of a high-pressure co-generation plant at Ponni Sugars Erode, India
Last Updated: julio 6, 2025This study was undertaken to address the high specific thermal energy consumption in sugar manufacturing, which directly impacts production costs and environmental sustainability. Ponni Sugars Erode Limited sought to overcome these challenges by investing in a modern, high-efficiency high-pressure cogeneration system.
Energy savings utilising dimple tube technology
Last Updated: julio 6, 2025In today’s sugar industry, due to rising fuel and electrical energy costs and the increased need for cogeneration, steam economy is a critical factor. Previously established options to upgrade vacuum pans for improved performance or steam economy are well known but are expensive and require extensive modifications to the vacuum pans.
Enhancing efficiency in the sugar industry: the role of mechanical vapor recompression (MVR) technology in optimizing energy consumption
Last Updated: junio 19, 2025Energy efficiency involves reducing the amount of energy consumed to achieve the same outcome. Mechanical vapor recompression (MVR) has long been recognized as a key technology for reducing primary energy consumption, by using electrical power, in steam-reliant processes across various industries.
