Taiwan’s Yangjia Feima Pro Series: Custom Coffee Roasters Explained

If you’ve been searching for a coffee roaster that delivers cleaner acidity, more defined sweetness, and fewer off-flavors like baked or underdeveloped notes, you’re not alone. Many specialty roasters struggle with uneven heat or inconsistent airflow that mutes origin characteristics. Taiwan’s Yangjia Feima PRO series aims to solve those problems—without sacrificing control or scalability.

The Yangjia Feima PRO series includes three models: the PRO-1 (1kg), PRO-4 (4kg), and PRO-6 (6kg). Released in late 2013, these machines are upgrades over the N-series, offering better heat penetration, enhanced flavor clarity, and customizable features—like color choices and a digital drum speed display.

What’s Different About the PRO Series?

The PRO series is a refined version of the earlier N-series machines. While the core functionality remains similar, Yangjia made key upgrades to both design and performance. Most noticeably, the internal boiler material has been changed to improve heat distribution and penetration. This results in more even roasts with brighter acidity, clearer sweetness, and a more layered flavor profile. Roasters also report fewer common defects, such as baked or under-roasted notes.

Additionally, the PRO models feature an extra set of internal paddles inside the roasting chamber. These generate a bidirectional airflow pattern, creating a mini tornado effect that enhances heat exchange and evenness throughout the drum. The result is more consistent development across the entire batch.

What Can You Customize?

Yangjia offers a unique customization service for the PRO series: you can choose your preferred roast machine color. The roaster is finished with a custom paint job based on your specification, adding a personal touch to your roastery setup. Just note that customized orders take about 60 days to deliver after payment, while standard colors are typically shipped within 45 days.

Beyond aesthetics, the PRO series also comes equipped with an electronic drum speed display. This allows roasters to monitor—and experiment with—the rotational speed of the drum in real time. Adjusting drum speed influences how beans contact the hot surfaces and air inside the drum, affecting roast development and flavor outcomes.

Which Model Is Right for You?

The PRO series is available in three capacities:

• PRO-1: 1kg batch size—ideal for small-scale or single-origin-focused roasters testing new profiles
• PRO-4: 4kg capacity—suits growing micro-roasters balancing volume and quality
• PRO-6: 6kg batch size—designed for established roasters needing moderate throughput without compromising on roast precision

All models retain the core improvements found in the PRO line: better heat distribution, airflow control, and flavor development. The larger capacities simply scale up the performance while maintaining the same engineering upgrades.
