SF-75: 75lb/34kg large coffee roaster machine with afterburner
The SF-75 is the largest drum coffee roaster available from the San Franciscan Roaster Company. Despite its size and power, The SF-75 is one of the quietest roasters in the world.
This robust commercial coffee roaster is surprisingly easy to control. The most discerning roastmaster will find they can control heating at each stage of the roast.
As a manual drum roaster, the SF-75 boasts a comfortable low-profile operator interface along with the classic San Franciscan Roaster styling. Strong, beautiful, and quiet, the SF-75 can be perfectly featured in larger coffee houses.
A Robust, Beautiful, and Environmentally Friendly Drum Coffee Roaster
The SF-75 is built for the artisan roaster. It features independent, 3-phase motors with variable speed capability controls on the drum drive and hot air. It is perfect for those who desire precise control over conductive and convective heat transfer.
To reduce environmental impact, the SF-75 features an energy-saving afterburner with modulating controls which clean both hot and cool air.
As a continuous batch roaster, the SF-75 roasts and cools at the same time. For this reason, it can manage four roasts per hour - a total of 300 lbs/hr. Making it perfect for artisan roasters with several coffee houses or a strong wholesale program. The total roasting time for each 75lb batch is 13-15 minutes.
You can customize your very own SF-75 with optional features that can suit your individual requirements. The hot and cooling air vent, afterburner, and cyclone-chaff collector can be modified to suit low ceilings.
Manual, Flexible Precision for Roasting
The SF-75 is the most flexible large-capacity drum coffee roaster on the market. It provides the same degree of control on roasts as our other smaller drum coffee roasters.
Even though it’s a manual roaster, the SF-75 can be fitted with a roaster controller for programming roast profiles.
