A reliable roast.
Every time.

  • Batch-to-batch consistency

    Stable thermal behavior and quick between-batch turnaround help keep profiles consistent from first roast to last.

  • Controlled convection

    Low air-bypass convection and optimized drum geometry are designed to minimize bypass and promote a more uniform bean environment.

  • Responsive, repeatable control

    100% electric power, and high energy recovery give you precise, repeatable control; whether you're roasting small development batches or 10kg production runs.

Roasting is all about managing heat.

Our 100% electric hot-air convection system goes beyond conventional roasting. The ERS transfers heat, not air, from exhaust to intake, preheating fresh incoming air without recycling roasting gases.

With our proprietary ERS active, internal A/B testing shows ~24% lower energy use and up to ~10% shorter roast cycles on top of our already efficient system.
Reference gas roaster~1.03 kWh/kg
DirectRoaster (ERS bypassed)~0.39 kWh/kg
DirectRoaster (ERS active)0.30 kWh/kg

These values use our internal reference baselines and A/B measurements (ERS active vs bypassed). Actual energy use depends on profile, throughput, and site conditions. How we measure

Built to solve
production pain points

Energy use and waste, infrastructure and compliance, and keeping profiles consistent at scale.

With a typical gas roaster
  • Energy costs tied to fuel prices and ventilation needs
  • Wasted heat leaving through the exhaust
  • Gas infrastructure, permitting, inspections
  • On-site combustion and compliance planning
  • Warm-up and stabilization time between runs
With DirectRoaster
  • Lower energy use vs. conventional gas roasting*
  • Designed for repeatable profiles
  • Simplified install: power + exhaust (no gas line)
  • No on-site fuel combustion (vent/filtration per local regs)
  • Shorter roast cycles with ERS active*

Sustainability

Roast electric.
For the future.

Energy recovery, built in

ERS transfers heat from exhaust to preheat fresh incoming air, reducing wasted heat in production roasting.

Built to Last

European build quality ensures decades of reliable operation. Less replacements, less waste.

Made in EU

Designed and manufactured in the Netherlands. Shorter supply chains, lower carbon footprint.

No on-site combustion

100% electric heat means no on-site fuel combustion. Like any roaster, exhaust still requires proper ventilation (and filtration where required).

Low Maintenance

Engineered simplicity means fewer parts to service. Modular design makes for fast and easy DIY repairs, if needed.

Designed for repeatability

Stable thermal behavior and responsive control help you keep profiles consistent across production runs.

Add Revenue. Not costs.

Taxes, emissions, rent, insurance, and premium coffee beans. Running a roasting company is complex enough. Your roaster shouldn't add to this.

The DirectRoaster operates on a standard 400V three-phase power supply (3Ø), which is common in commercial and industrial settings across Europe and many other regions. Power consumption is remarkably efficient at approximately 0.3 kWh per kilogram of coffee roasted. Our team will assess your electrical setup during the site survey to ensure compatibility. In most cases, existing commercial electrical infrastructure is sufficient.

Yes. Like any roaster, you must properly vent smoke and roasting byproducts, and comply with local codes. DirectRoaster includes an integrated chaff collection system to capture chaff before it reaches the exhaust ducting, but it does not eliminate the need for proper ventilation (and filtration where required). The advantage is that DirectRoaster is 100% electric with no on-site fuel combustion and no gas line, so installation is often simpler and more flexible for cafés and urban spaces. We can advise on ducting and filtration options if your local regulations require them.

The DirectRoaster requires just 1.54m² of floor space (160cm × 96cm). The fully integrated design includes the roaster and control system in one unit. additional room for the DR Cooling tray may be required.

The standard DirectRoaster is stainless steel, with matte black insulation panels. Custom color options may be available for larger orders. Please contact our sales team to discuss your specific requirements and lead times.

No. The DirectRoaster is engineered from the ground up as a 100% electric hot-air convection roaster. The entire thermal system, including the proprietary Energy Recovery System (ERS), is optimized for electric operation. This isn't a limitation, it's the point. Electric operation enables responsive control, no on-site fuel combustion, and simpler installation without a gas connection.

Yes! The DirectRoaster's precise temperature control and hot-air convection make it excellent for roasting a variety of products including cacao nibs, various nuts (almonds, hazelnuts, peanuts), grains, and seeds. Please note that dedicated batches are recommended to avoid flavor cross-contamination.

The DirectRoaster is designed for continuous production. With the ERS keeping the system at optimal temperature and our fast between-batch protocol, you can roast back-to-back batches all day. At maximum throughput with 10kg batches, you can achieve approximately 60kg per hour. The between-batch turnaround is typically just 2-3 minutes.

The DirectRoaster logs comprehensive roast data including bean temperature, drum temperature, airflow rates, time curves, and all user inputs. Data can be exported for analysis and is compatible with Cropster (integration coming soon). Supports per-batch roast logging for QA and auditing.

The DirectRoaster handles batch sizes from 1kg to 10kg, giving you flexibility for both development batches and full production runs in a single machine. Note: for true sample roasting (typically 50–100g), most roasteries still use a dedicated sample roaster; 1kg is best thought of as small-lot development and QA.

Roast times typically range from 4 to 12 minutes depending on your profile, batch size, and desired development. The hot-air convection system provides responsive heat transfer, giving you precise control over roast progression. Most medium roast profiles complete in 8-10 minutes.

The ERS is a heat exchanger (not an air recycler) that captures thermal energy from the exhaust and transfers it to preheat incoming fresh air. Important: the air itself is never recycled, only the heat is transferred. In internal A/B testing, running with ERS active reduced energy use by ~24% and shortened roast cycles up to ~10% versus the same roaster with ERS bypassed. In steady-state conditions, the ERS can recover a large portion of exhaust heat (up to ~75% in our engineering tests). See the Methodology page for definitions and conditions.
