Bühler is a Swiss industrial processing giant founded in 1860 that entered coffee roasting around 50 years ago. they completely redesigned their roaster lineup in 2010, positioning themselves at the scale end of the market with the RoastMaster series: four sizes spanning 20 to 240 kg batch capacity, plus the InfinityRoast for continuous high-volume operations up to 4000 kg/hr throughput. their machines are single-pass indirect flame gas drum roasters built with solid single-walled carbon steel construction. mechanical assembly happens in India, with control panels and final assembly done in Minneapolis. Bühler targets large-scale commercial roasters and industrial operations that need consistent output, full automation, and the ability to integrate roasters into complete processing lines. they offer turnkey plant design services, afterburners, optical sorters, grinders, and destoners. the machines feature full digital data output and are UL certified. buyers here are looking at serious production volume, not exploration or flexibility. this is a manufacturer for operations that know their profiles, need repeatable results at scale, and want a supplier that can support everything from engineering to maintenance.
mechanical assembly happens in India, then control panels and final assembly are completed in Minneapolis, Minnesota. Bühler is a Swiss company headquartered in Uzwil, but they handle manufacturing and assembly across multiple facilities. if you're buying a RoastMaster or InfinityRoast for the North American market, final assembly and commissioning come out of the Minneapolis operation. warranty and service are handled through that facility as well.
Bühler offers a one-year manufacturer warranty and recommends a $5000 service package that covers commissioning and startup, including one week of on-site visits from a Bühler service technician. beyond that, they provide full engineering and project management services if you're building out a complete processing line. their global footprint means they can handle installation, maintenance, and technical support in most regions. rent-to-own financing is available through some distributors.
Bühler makes sense if you need a roaster that integrates into a larger processing system or if you're running a high-volume operation that values consistency over profile experimentation. their strength is in repeatable automation and full plant design, not hands-on roasting flexibility. if you're a contract roaster doing multi-ton daily output or an operation that wants one supplier for roasting, sorting, grinding, and emissions control, Bühler can handle that scope. smaller batch roasters or those who want more manual control should look elsewhere.
