Kandla, Gujarat: In a record-setting feat of sustainable engineering, Spray Engineering Devices Ltd. (SED), a global provider of sustainable industrial engineering solutions, has successfully commissioned a landmark sugar refinery capacity expansion and energy optimisation project for Shri Dutt India Private Limited (SDIPL)’s facility in Kandla, Gujarat, India. Executed in a record timeframe of under twelve months, the project scaled the sugar refinery’s capacity from 1,000 tonnes per day (TPD) to 2,500 TPD, without requiring any additional boiler investment.
Among the fastest large-scale expansions in India’s sugar sector, the project establishes a new benchmark for rapid, energy-efficient industrial scaling. By modernising existing infrastructure rather than adding capital-intensive utilities, SED demonstrated how significant capacity growth can be achieved sustainably, even under aggressive timelines.
Vivek Verma, Managing Director, Spray Engineering Devices Ltd stated: “This project demonstrates the capability of our latest Batch Crystallisation Pans to operate at extremely low Delta T levels. By optimising heat transfer, we enabled Shri Dutt India to more than double its output while retaining its existing steam generation infrastructure, reinforcing that engineering innovation is central to sustainable industrial growth.”
Jeetendra Dharu, Director, Shri Dutt India Private Limited, added: “The entire project was completed from concept to commissioning in less than twelve months – a testament to seamless coordination between teams and SED’s commitment to meeting tight execution timelines.”
Key Project Highlights:
- 2.5x Capacity Expansion: Scale-up from 1,000 TPD to 2,500 TPD
- Infrastructure Optimisation: MVR-based system eliminated the need for new boiler investments
- Proprietary Technology: Honeycomb Calandria Batch Pans operating at industry-leading 20–25°C Delta T
- Fast-Track Delivery: Concept-to-commissioning completed in under 12 months
At the heart of the project is SED’s proprietary integration of Mechanical Vapour Recompression (MVR) with Batch Crystallisation Pans equipped with Honeycomb Calandria technology. Operating at an ultra-low temperature differential (Delta T) of just 20–25°C, the system maximises heat transfer efficiency while substantially reducing steam consumption.
Priti Ruparel, representing the leadership at SDIPL, remarked: “This was a significant challenge in terms of both time and technology. We trusted SED’s technical prowess, and they delivered a truly world-class sugar refinery.”
By eliminating the need for new boiler infrastructure, the sugar refinery achieved a 2.5x capacity expansion with a significantly lower carbon footprint, underscoring that technological innovation, not added utilities, is key to sustainable industrial growth.
