German PROBAT Coffee Roasters: Brand History & Models

If you’ve ever wondered how specialty coffee roasters achieve consistent, high-quality roasts at scale—or why certain commercial roasters dominate global markets—you’ve likely encountered the name PROBAT. But what makes this German brand such an industry standard, and what equipment do they actually produce? This guide breaks down PROBAT’s history, technology, and product range without the fluff.

In short: Founded in 1868 in Emmerich, Germany, PROBAT introduced the first high-capacity coffee roaster and has since sold over 100,000 units globally. Today, it offers a full range of roasters from 1.2kg lab models to 640kg industrial machines, used by major coffee companies worldwide.

Brand Origins: From Railway Boom to Roasting Revolution

In 1864, Alexius van Gülpens, a coffee bean merchant in Emmerich, Germany, saw opportunity in selling freshly roasted coffee to retailers beyond his local area—thanks to new railway lines. But he faced a major hurdle: there was no high-capacity roaster that could keep up with demand. That need led him to team up with local engineer Theodor von Gimborn. After four years of development, they launched the first high-output coffee roaster in 1868. This innovation gave birth to what would become PROBAT. By 1880, the company was selling over 600 roasters annually. By 1900, that number hit 50,000 units, and by 1938, the 100,000th unit was sold. The company officially adopted the PROBAT name in 1938. To this day, around 80% of PROBAT’s sales come from exports to more than 60 countries.

How PROBAT Roasters Work: Design & Technology

PROBAT roasters are built around a rotating drum system that moves coffee beans continuously in multiple directions—front to back, side to side—using specially designed internal blades. This ensures even heat distribution and consistent agitation throughout the roast. Heat is supplied via a mix: 30% comes from direct conduction and radiation, while 70% is delivered through forced hot air. The exterior of the drum is wrapped in insulating material to retain heat, improving thermal stability and making it easier to replicate roast profiles. This design minimizes common roasting defects and supports uniform development, crucial for high-quality specialty coffee.

PROBAT Product Range: From Lab to Industrial Scale

PROBAT manufactures a wide spectrum of coffee roasting equipment, including small lab roasters and large commercial systems. Their product lines include:

• Probatino: 1.2kg capacity, ideal for lab use and small-batch experimentation.
• Probatone: Available in 5kg and 12kg capacities, suitable for boutique and specialty roasters.
• SATURN Series: Centrifugal roasters with capacities from 32kg to 640kg per batch.
• JUPITER Series: Tangential (cutting) roasters ranging from 50kg to 750kg.
• NEPTUNE Series: Traditional drum roasters with capacities between 80kg and 640kg.

All roasters above 5kg can be connected to computer systems to record and control roast profiles automatically, allowing for precision and repeatability in the roasting process. In addition to roasters, PROBAT also produces cocoa, malt, and nut processing equipment, as well as optional laboratory testing tools, green coffee grading systems, and exhaust gas handling solutions.
