San Franciscan SF-150: 68kg Industrial Coffee Roaster Specs

If you’re sourcing or upgrading a commercial coffee roaster capable of handling serious volume without compromising on durability or control, you’ll need exact specifications—not marketing claims. Industrial roasters demand precision in heat delivery, airflow management, safety systems, and maintenance logistics. This article breaks down the full technical profile of one of the most robust machines on the market.

The San Franciscan SF-150 is an industrial coffee roaster with a 600 lbs (approximately 272 kg) batch capacity, built to handle high-volume production. It weighs 3,850 lbs (1,746 kg), measures 8' wide × 12' long × 12' high, and includes a 14" diameter exhaust pipe. It operates on 220V single-phase or 220–440–480V three-phase power, with customizable voltage to meet international standards.

Key Technical Specifications

The SF-150 delivers 500,000 BTUs of heating power and supports both natural gas (7" water column) and propane (11" water column). Its gas line requires a 1 1/4" connection, and it includes a 1/2" pipe thread for water quenching. The roaster offers manual or automatic operation, timed high and low afterburner temperature controls, full motor protection, high-temperature cutoff, and flame safeguards. Temperature modulation is precise, and data archiving is supported. Electrical components are UL-approved and compatible with 50 or 60 Hz systems.
