- Dual fuel capability
A bold step forward in malt roasting
Dingemans, a leading family-owned malt producer known for its product quality and innovation mindset, has taken a pioneering role in the sector by introducing the first continuous, fully electric malt roaster. CEE’s new roasting technology helps Dingemans drastically improve energy efficiency, process safety and consistency — transforming the traditional roasting process from a risk-intensive, slow and energy-hungry operation into a controlled, agile and clean production method.
The collaboration between Dingemans and CEE didn’t come out of nowhere. Having worked together for years on process and utility optimization, both partners understood the roasting process inside out. When trials with CEE’s high-precision electric system — initially designed for coffee — exceeded expectations in malt, the ambition to scale was immediate.
What truly won Dingemans over was not just the improved speed and efficiency, but the peace of mind this system delivers. Malt roasting is notoriously risky, and the prospect of running a process without constant monitoring — safely and cleanly — opens new operational possibilities. With this project, Dingemans sets a new benchmark for the entire industry.
Up to 8x less energy, zero emissions
The new roasting line at Dingemans consumes just 150–250 kWh per ton, with no CO₂ emissions when operated in full-electric mode — a remarkable leap from traditional batch roasting. The system leverages the exothermal nature of the malt roasting process instead of fighting it, avoiding quenching and reclaiming internal heat efficiently.
Thanks to the continuous nature of the roasting process, the exhaust gas flow is stable and predictable — making it ideally suited for the use of flameless regenerative thermal oxidizers (RTOs). These systems are designed for continuous operation and can now also be fully electrified, allowing even the exhaust treatment to run cleanly and efficiently. The result is not just lower direct emissions, but a significant reduction in overall environmental impact and operating costs
Safety by design
Traditional malt roasters rely on quenching to prevent fires — a method that wastes energy, adds time to the roasting process and interrupts the development of the grains. CEE’s high-precision roaster eliminates this need thanks to ultra-precise control and inherent safety features: low product volumes in the hottest zones, fire and CO detection systems, and open non-pressurized architecture.
Faster production, same high quality
CEE’s continuous roaster cuts production time from 2.5 hours down to just 20–30 minutes, without compromising on flavor or color. End moisture can be dialed in at the end of the line, allowing unmatched consistency — a huge win for Dingemans’ premium product line.
With this breakthrough, Dingemans can continue to lead the malt industry in both craftsmanship and innovation — and we’re proud to stand by their side in that journey.
