Bühler InfinityRoast

the verdict

the InfinityRoast is Bühler's continuous roaster designed for operations pushing serious volume, reportedly handling up to 4000 kg per hour throughput. it's fully automated with gas-fired drum heating and batch sizes from 30 to 180 kg depending on configuration. this is not a machine for roasters who want to tinker with profiles or explore different origins weekly. it's built for industrial-scale operations that have locked in their blends, need consistent output hour after hour, and want minimal operator intervention. mechanical assembly in India with final assembly in Minneapolis keeps costs more competitive than full Swiss manufacture, but you're still looking at a significant capital investment. the single-walled drum construction and single-pass airflow design prioritize throughput and efficiency over the kind of heat manipulation smaller roasters rely on. service and commissioning require Bühler technicians, so factor in that dependency. if you're running a large contract roasting operation, a high-volume private label facility, or an industrial coffee processing plant, this machine delivers repeatable results at scale. smaller roasters or those still refining their approach should stay in the batch roaster range.
