The next generation of coffee roasting

The DMR5-A

The next generation of coffee roasting

The DMR5-A

The DMR5-A was developed for coffee roasters seeking maximum control, consistent results, and flexibility in a compact machine. From sample roasting and profile development to daily production, the DMR5-A provides complete control over heat, airflow, and drum speed, allowing each roast profile to be precisely built and replicated.

Built in the Netherlands, developed for real-world use, and designed for years of reliable service.

Each roaster is built with high-quality, heat-resistant sheet materials and equipped with advanced insulation.Thanks to a smart mechanical design and intelligent software, a nauwkeurige ROR (Rate of Rise) achieved, while the system operates sustainably and energy-efficiently.

Het regelsysteem van de DMR5-A is ontwikkeld vanuit jarenlange ervaring in koffiebrander-automatisering.

Waar traditionele systemen vaak werken met vaste instellingen, reageert de DMR5-A direct op wijzigingen in warmte, luchtstroom en procesinstellingen. Hierdoor ontstaat een stabieler brandproces met meer controle over de Rate of Rise en een hogere reproduceerbaarheid van brandprofielen.

Motoren en ventilatoren worden uitsluitend geactiveerd wanneer nodig, wat zorgt voor een lager energieverbruik, minder slijtage en een stillere werkomgeving.

Dutch design. Built to last.

Bij de ontwikkeling van de DMR5-A is niet alleen gekeken naar prestaties, maar ook naar gebruiksgemak, onderhoud en uitstraling.

De machine wordt gebouwd met hoogwaardige materialen, een duurzame afwerking en een ontwerp dat eenvoudig toegankelijk blijft voor reiniging en onderhoud.

Daarnaast kan de brander worden uitgevoerd in kleuren die aansluiten bij de uitstraling van de branderij.

The smart baseboard lighting provides a visual indication of the roasting process status: functional and aesthetic at the same time.

 ovCompatibel met Cropster and Artisanallowing you to easily analyze data and optimize workflows. All components, from roaster to destoner, can be operated via the Dutch Master Roasters App (iPad).

Dankzij de toegankelijke opbouw is elke DMR-brander snel en eenvoudig te servicen. Via de LAN connection we offer remote support. Always close, wherever you are roasting.

Precision and control in every roast

Technology that thinks along with you

The control system of a Dutch Master Roaster has been developed on the basis of many years’ experience in coffee roaster automation. Thanks to this expertise, a platform has been created that combines precision, control and consistency in a single system.

Whereas conventional burners often operate with fixed settings, the DMR responds dynamically to changes in the process. Heat, air flow and ventilation are precisely controlled, ensuring that the burners maintain maximum control over every stage of combustion.

The combination of intelligent software and a robust machine design ensures stable energy transfer and reproducible results. This makes it easier to develop, analyse and replicate burn profiles.

In addition, motors and fans are only activated when necessary. This results in lower energy consumption, less wear and tear, and a quieter working environment.

The green bean loader

With our green bean loader, loading the coffee roaster becomes a simple and precise task.

The loader is fully controlled via the Dutch Master Roaster iPad app, where you can also see exactly how much coffee is being loaded. Thanks to the integrated weighing function, you always know precisely how much green coffee you are roasting: convenience and control in one system.

Because you can read both the weight of the green coffee before roasting and that of the roasted coffee in the cooling sieve, you always have immediate insight into your net yield.

A smart and efficient solution that provides consistent insight with every roast.

 

The destoner

As the name suggests, the destoner is designed to remove stones from coffee. During the processing and packaging of green coffee, small stones can end up among the beans. Naturally, you don’t want these in your coffee machine, as they can seriously damage the grinder. 

To remove these unwanted particles from the roasted coffee, the beans pass through the destoner. Our destoner is specially designed with organic coffee in mind and requires minimal maintenance. While other systems use a leather chute to drop the coffee into the silo—a component that requires regular maintenance and replacement—our destoner operates completely without obstructions.

Thanks to the use of gravity and the difference in density, the flow proceeds smoothly and naturally. This keeps the coffee undamaged and uncontaminated, while minimizing maintenance.

The control of our destoner is managed via the Dutch Master Roasters iPad app. Since the destoner is directly connected to the coffee roaster, no additional connection is required.

Eco filters

The ECO-15 is designed for effective and eco-friendly odor filtration during the coffee roasting process.

The system contains two filter cartridges that together ensure an odorless final result and also capture the released essential oils, creating a cleaner and safer working environment.

The ECO-15 can process 6 to 15 kilograms of roasted coffee per batch, making it ideal for artisanal coffee roasting.

The filters do not require a gas or electricity connection, making the system energy-efficient and easy to use. Thanks to the high-quality carbon filters, roasting can be done for up to 1,000 hours without any noticeable loss of filtration performance.

Intuitive control via iPad

Dutch Master Roasters App

The DMR5-A is controlled entirely through the Dutch Master Roasters app.

Thanks to the user-friendly interface, temperature curves, airflow, and process data can be monitored in real time. Each firing cycle is automatically saved, making it easy to analyze, compare, and repeat profiles.

The app is available on the App Store and receives regular updates, ensuring that new features remain available to existing users as well.

Advantages:

✅ Real-time insight into every roast
✅ Automatic saving of roast profiles
✅ Compatible with Cropster and Artisan
✅ Easily compare past surf conditions
✅ Software updates via the App Store
