The SF-75 — The San Franciscan Roaster Company's Largest Coffee Roaster

SFR-75-2024

SF-75: 75lb/34kg large batch roaster 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. It is robust, yet easy to handle and responsive to the most discerning of roastmaster controls. With its ability to roast 300 lbs/136 kg of green coffee per hour, the SF-75 is perfect for artisan roasters with several coffee houses or with a strong wholesale program. As a manual drum coffee 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 drum drive and hot air for those who desire precise control over conductive/convective heat transfer. In order 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, the SF-75 can do four roasts per hour (300 lbs). Roasting time is 13 to 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.

What Other Roastmasters think of San Franciscan Roasters

"We love their old style look mixed with good electronics"


"We have two 25lb San Franciscan roasters named Frannie and Cisco. As Roastmaster, I love roasting on these two work horses. I roast simultaneously on both of them, with no problem. We love their old style look mixed with good electronics. If maintainence is kept up, they will work well. As a good companion, we roast all our samples on our 1lb San Franciscan, keeping them harmonious with our roasting process."

Paul Allen - Roastmaster Caravan Coffee

"They've built a world class team around their world class roasters"

"The San Franciscan Coffee Roaster Co. has built a world class team around their world class roasters. Every person we have had the pleasure of working with is extremely knowledgeable in their craft and it shows in their final product. We have been using the same workhorse SF-25 for almost 30 years, so when it finally came time to purchase a new roaster we had no doubt it would be another San Franciscan. The American craftsmanship and American steel insure we will have another 30 years with our new SF-25. The pride they take in their craft shows and it allows us to take pride in ours."

"They took the roasting experience and perfected the process!"

San Franciscan Roaster Co. were so helpful and worked with us from the beginning (our first phone call with them) to our first roasting experience. They helped with deciding which roaster size would be best for our size business. We were put in contact with other coffee roasters who had purchased a San Franciscan Roaster to get feedback. We met some very awesome people who have had the San Franciscan Coffee Roaster for well over a decade and loved it!

The San Franciscan SF6 Coffee Roaster has been reliable and very easy on maintenance. Since we are in a very rural area (the mountains), they were able to guide us through standard maintenance and then some. We have been operating our SF6 Coffee Roaster now for 2 years and have not had any problems.

The roasting process with the San Franciscan is great...our coffee has had very high praise. They took the roasting experience and perfected the process!

If one day we decide to double our business we would definitely buy another San Franciscan Coffee Roaster!
