The San Franciscan Roaster Company's SF-75/35kg industrial coffee roaster

The SF75—The San Franciscan Roaster Company's Largest Coffee Roaster

The SF75 is the largest coffee roaster available from the San Franciscan Roaster Company. Despite its size and power, The SF75 is one of the quietest roasters in the world. It is robust, yet easy to handle and responsive to the most discerning of roastmaster controls. With its ability to roast 300 lbs of green coffee per hour, the SF75 is perfect for artisan roasters with several coffee houses or with a strong wholesale programs. As a manual coffee roaster, the SF75 boasts a comfortable low-profile operator interface along with the classic San Franciscan Roaster styling. Strong, beautiful and quiet, the SF75 can be perfectly featured in larger coffee houses.

A Robust, Beautiful, and Environmentally Friendly Coffee Roaster

The SF75 is built for the artisan roaster. It features independent, 3-phase motors with variable speed capability controls on drum drive and hot air for those who desire precise control over conductive/convective heat transfer. In order to reduce environmental impact, the SF75 features an energy saving afterburner with modulating controls which cleans both hot and cool air. As a continuous batch roaster, the SF75 roasts and cools at the same time. For this reason, the SF75 can do four roasts per hour (300 lbs). Roasting time is 13 to 15 minutes. You can customize your very own SF75 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 SF75 is the most flexible large-capacity coffee roaster on the market. It provides the same degree of control on roasts as our other smaller coffee roasters. Even though it’s a manual roaster, the SF75 can be fitted with a roaster controller for programming roast profiles.
