diedrich roasters

diedrich roasters has been building drum roasters in ponderay, idaho since 1984. the company's signature feature is its patented infrared burner system, which places the heat source inside the drum rather than underneath it. this design offers different heat distribution compared to traditional gas burners and has earned the brand a loyal following among roasters who prioritize thermal stability and repeatability. the IR series spans from 1kg sample roasters to 24kg production machines, all sharing the same burner design and build quality. diedrich positions itself in the premium segment of the north american market. their machines are built heavy, with thick steel construction and straightforward mechanical systems that technicians can actually work on. the control options range from fully manual on smaller models to profile logging capability on the 5kg and up. roasters appreciate the consistent heat delivery and the fact that these machines hold value on the used market. if you want proven infrared technology and don't mind a learning curve that's different from conventional burner placement, diedrich deserves consideration. they're particularly popular with shops that plan to keep machines running for 15-20 years.
