What You Should Know About Our Commercial Coffee Roasters 

At the San Franciscan Roaster Company, our team builds the best commercial coffee roasters in the world. We’ve achieved this distinction by paying close attention to every detail. From the materials used to the ease of maintenance, our commercial coffee roasters are hand-fabricated to produce an experience of the highest quality, time and time again.

Materials — Commercial Coffee Roasters Built with 100% Schedule 40 Domestic Steel

Reliability is crucial when it comes to commercial coffee roasters. Every San Franciscan Coffee Roaster is built with domestic steel instead of foreign steel. Unlike other roasters, which are built with lower-quality steel imported from Asia, San Franciscan Roasters are built from hand-fabricated, 100% schedule 40 domestic steel. 

Our commercial coffee roasters yield more even heat diffusion characteristics, resulting in precision-conductive heating transfer. Domestic steel is strong and tough but not tempered. Due to the superb heat diffusion characteristics of mild carbon steel, the temperature of the entire surface of the inside of the drum will be consistent.

Single-Walled Drums — Precision-Conducting Heating Transfer Capabilities

Our single-walled drums give roastmasters the ability to get as involved with the roasting process as possible. We intentionally avoid double-wall drums in our roasters as they limit the heat application by conductivity. 

Many Different Sizes Available to Suit Your Needs

Every San Franciscan™ roaster is made proportionally, giving you the freedom to duplicate roasts across our entire line of machines. In fact, you won't be able to tell the difference in blind cuppings! This is particularly impressive if you’d like to develop a premium profile that can be easily duplicated with a larger roaster. 

Size is a big factor when it comes to choosing the right commercial coffee roaster. Perhaps your roasting business is just starting out or maybe you’d like to expand your workload. 

From the SF-1 to the SF-75: The Entire Spectrum of Commercial Coffee Roaster Sizes

No matter where you currently find yourself in your commercial coffee roasting venture, the San Franciscan Roaster Company has the right machine for you. Our five size options are as follows:

  • SF-1: Roasts 1 pound/500 grams
  • SF-6: Roasts 6 pounds/3 kilograms 
  • SF-10: Roasts 10 pounds/5 kilograms 
  • SF-25: Roasts 25 pounds/12 kilograms 
  • SF-75: Roasts 75 pounds/34 kilograms 

A Closer Look at Our Roaster Sizes

  • The SF-6 and SF-10 are excellent roasters for small-batch coffee roasting, while the SF-25 and SF-75 are more adept for large quantities. 
  • Due to its small batch size, the SF-1 is ideal for training and sample roasting. If you’d like to learn more about the size of our machines, click here. You could also give us a call or send us an email, and we’ll be able to provide more detailed assistance. 
  • If you’re roasting more and more and you require a more efficient machine for large-batch roasting, then the SF-25 or SF-75 will be perfect. Our two largest roasters also come standard with afterburners.

No matter your needs or goals, we’ll be able to provide the right machine (or machines) for you to embrace the craft of coffee roasting completely. Choosing the right size depends entirely on your particular situation, needs, and requirements. At the San Franciscan Roaster Company, we have the right size roaster to perfectly suit your needs!

Control of the Craft with State-of-the-Art Data Logging Technology 

By making use of excellent data-logging software such as Cropster and Artisan, today’s generation of coffee roasters is able to embrace creativity and experimentation. Having all the right data points may help in some regards, but it doesn’t particularly mean you’ll make the perfect roast time and again. 

While the data might say a roast should be perfect, your coffee roasting senses may say otherwise. San Franciscan roasters are designed specifically to enhance the roastmaster’s ability to use his or her physical senses while roasting. This way, you’ll be able to embrace (and control) the craft as completely as possible!

It’s necessary for roastmasters to embrace the craft of commercial coffee roasting, and our roasters make that a reality! The San Franciscan Roaster Company strives to keep the spirit of artistry alive in the world of specialty coffee roasting. 

At the San Franciscan Roaster Company, we like to say, “don’t fear the craft; embrace it!” We think technology can save us from mistakes. But technology can very easily go awry when you have the wrong inputs. More often than not, people are afraid to use their own senses to bring correction to a roast. 

Our Roasters Feature the Ability to Change Rotational Velocity

By changing the rotational velocity of the outside diameter of the drum, roastmasters can also change the contact time the bean has with the drum. This changes the ratio of conductive vs. convective heat transfer. It’s important to point out, however, that one does not have to change rotational velocity very much to get a different outcome in the cup. This design option is only available in the SF-10, SF-25, and SF-75 roasters. 

Meticulously Designed for Efficient Cleaning and Maintenance 

Not only is commercial coffee roaster maintenance important, but it’s also crucial for the overall usefulness and functionality of the machine. We’ve designed our machines for maintenance to be as efficient and palpable as possible. Roastmasters are able to get to every part of their San Franciscan roaster easily. Everything is easy to access. Since the parts are removable, cleaning becomes less of a hassle.
