German PROBAT Coffee Roasters: Probatone and Probatino Explained

If you’ve ever wondered how your local specialty coffee shop gets those consistent, high-quality roasts—or how global brands like Lavazza and UCC maintain such reliability batch after batch—the answer often starts with the roaster. Many pros rely on German-engineered machines built to deliver repeatable results. But which models are built for precision, durability, and export-ready performance? This article breaks down the legacy and tech behind two key PROBAT models: the compact Probatino and the mid-capacity Probatone.

PROBAT, founded in 1868 in Emmerich, Germany, is one of the oldest and most trusted names in commercial and specialty coffee roasting. Today, its best-known small and mid-volume roasters—the 1.2kg Probatino and the 5kg/12kg Probatone—continue to lead in durability and consistency, used by major coffee companies around the world.

The Origins of PROBAT: From Railway to Roastery

In 1864, Alexius van Gülpren, a pioneer coffee bean merchant in Emmerich, Germany, saw opportunity in the newly built railways: he wanted to deliver freshly roasted coffee beans to retailers farther afield. But there was a problem—there was no high-capacity roaster that could keep up with the demand. That need led him to team up with local engineer Theodor von Gimborn. After four years of development, the first high-capacity commercial coffee roaster was born in 1868, launching what would become PROBAT. By 1880, the company was selling over 600 roasters per year; by 1900, more than 50,000 units; and by 1938, the 100,000th machine was sold. The company officially became PROBAT-Werke. At its peak, 80% of sales were exports to over 60 countries.

How PROBAT Roasters Work: Design & Technology

PROBAT roasters—including the Probatino and Probatone—are built for consistency and control. Their drum roasting design rotates on multiple axes (front-to-back and side-to-side), with specially designed blades that ensure constant agitation of the beans for even heat application. Heat is supplied using a mix: 30% comes from direct conduction and radiation, while 70% is delivered via hot air. The drums are wrapped in insulating material to retain heat, ensuring stable internal temperatures and reducing the chances of common roasting defects. This thermal stability helps roasters achieve the same profile time after time.

Probatino and Probatone: Models and Capacities

Among PROBAT’s specialized offerings for specialty and craft roasters are:

• Probatino: 1.2 kg capacity, ideal for lab use, sample roasting, and small-batch development.
• Probatone: Available in 5 kg and 12 kg capacities, suitable for small-to-mid-volume production environments.

Both models, along with larger PROBAT units, can be equipped with optional accessories, including lab test devices, green coffee grading tools, and exhaust gas handling systems. The 5kg and larger PROBAT roasters can also be connected to computer controls to record and automate roast profiles.
