German PROBAT Coffee Roasters: Brand, Models & Features

If you’ve ever wondered how specialty coffee roasters produce consistent, high-quality batches at scale—or how global coffee brands maintain uniform roast profiles—you’re not alone. The answer often starts with the roasting equipment, and one name has been behind some of the most reliable machines for over 150 years: PROBAT.

Founded in 1868 in Germany, PROBAT introduced the first high-capacity commercial coffee roaster and remains a leading manufacturer of professional-grade roasting equipment, with models ranging from 1.2kg to 640kg and a global install base exceeding 100,000 units.

Origins of PROBAT: From Railway Boom to Roasting Innovation

In 1864, Alexius van Gülpren, a pioneering green coffee bean merchant in Emmerich, Germany, saw an opportunity to distribute freshly roasted coffee to retailers beyond his local area—thanks to new railway lines. But there was a major hurdle: he needed a high-capacity roaster. That need led him to team up with local engineer Theodor von Gimborn. After four years of development, the pair launched the first large-scale production roaster in 1868, giving birth to what would become PROBAT. By 1880, the company was selling over 600 roasters annually; by 1900, more than 50,000 units had been sold worldwide. The 100,000th machine rolled out in 1938, and the company officially adopted the PROBAT name. Eighty percent of those sales were exports, with machines shipped to over 60 countries.

PROBAT Roaster Design & Technology

PROBAT’s core coffee roasting equipment—including the compact Probatino (1.2kg), Probatone 5kg, and Probatone 12kg models—uses a unique drum rotation system that turns in multiple directions. This design, paired with specialized internal blades, keeps coffee beans in constant motion for even heat application. Heat is supplied via a mix: 30% comes from direct conduction and radiation, while 70% is delivered through forced hot air. The roasting drums are wrapped in insulating layers to retain heat, improving thermal stability and making it easier to achieve consistent results across batches. The build quality minimizes the need for manual adjustments during roasting, resulting in fewer common roast defects. The intuitive control interface also helps operators maintain precision without complication. Additionally, PROBAT offers optional accessories such as lab test equipment, green coffee grading tools, and exhaust gas handling systems. Major coffee companies like LAVAZZA and UCC rely on PROBAT machines for their consistent output.
