Roaster Dynamics RD-6 Coffee Roaster with Convertible Function & Near-New Condition

The Roaster Dynamics Tech-tisian RD-6 is a 6 kg / 3 kg industry first in convertible roasters built by Paul Ribich under Roaster Dynamics, LLC. It’s a like-new condition as used only 12 times, and it can roast 3-4 batches per hour, thanks to its ability to roast and cool at the same time. 

This state-of-the-art drum roaster features natural gas firing, a dedicated operator cabinet, and separate exhaust ducting for both roast air and cooling. Compatible with Cropster and Artisan data logging platforms, it can easily switch between 6kg and 3kg capacities. The manual is available online, making onboarding and maintenance straightforward for any operator.

With near-new condition and only a handful of roasts on the clock, this Roaster Dynamics 6 kg roaster is a rare find among used coffee roasters and used roastery equipment. Sold as-is from the East Coast USA, contact us today before this opportunity is gone.
