Commercial Coffee Roasting Machines

Perfectly roasted coffee with the best coffee roasting machine

The Perfect cup of coffee does not Just happen randomly

IThe perfect cup of coffee starts with quality coffee beans. The green beans must then go through a process which should bring out their best flavor. With a commercial coffee roaster machine.

The roasting process literally makes or breaks a great coffee brew. A quality coffee roasting machine will allow the roastmaster to work their magic on those beans. But, a poor-quality commercial roasting machine can inevitably reduce them to a bitter, acidic tasting brew. resembling something you’d typically get from a fast-food drive through.

The secret is control and consistency. The right combination conduction, convection and radiant heating, is needed at each stage of the roast. A commercial drum roaster is best, made of high quality US steel, with no impurities to impend the even spread of heat. A little convection heating is needed to burn the impurities, but too much will also remove the flavor.

That’s what it takes to create a cup of coffee people rave about. Coffee they will come back for, year after year.

The 3-step Formula for roasting perfect coffee



A good cup of coffee starts with quality beans, grown in remote locations at high altitudes. We're lucky to have them, so it’s almost a crime to destroy them with a poor quality coffee roaster.



Expertise from training with masters in the craft of coffee roasting. That’s why San Franciscan employ some of the best roasters in the business and hold regular training sessions for our clients.



Consistency comes from a coffee roaster made of quality materials, that responds perfectly to your controls. It disperses heat evenly and gives you consistency throughout your roasts.

What You Should Know About Our Commercial Coffee Roasting Machines


At the San Franciscan Roaster Company, our team builds the best coffee roasting equipment for commercial use, in the world. We achieve this by paying close attention to every detail. We don't compromise on components - we use only the best US-made bearings, motors and fittings.

When you invest in a coffee roaster for commercial use, you need reliability, consistently and ease of maintenance. That's why we hand fabricate our commercial coffee roasters, to give you the performance you expect, time and time again.

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

Unlike cheaper roasters, built with lower-quality imported steel, we don't compromise on quality. Every a San Franciscan Roaster™ is hand-fabricated, using 100% schedule 40 US 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. The temperature of the entire inside drum surface remains consistent while you roast. This is purely because of the superb heat diffusion characteristics of US mild carbon steel.

Single-Walled Drums — Precision-Conducting Heating Transfer Capabilities

While some manufacturers will tell you that double-walled drums are best, this is because they are using inferior steel with poor conductive properties. To cover for the uneven heating and lack of control, they are forced to use a double wall.  Read more about the single-wall vs double-wall debate.

Our single-walled drums are more responsive to heating controls. They give roastmasters the ability to get as involved with the roasting process as is possible. For that reason, We avoid double-wall drums on our roasters as they limit the control you have with heat application.  

All Our Machines are Proudly Hand-made in the USA

In addition to only using US made material and components, we also build every machine by hand, at our factory in Carson City, Nevada. Each roaster is lovingly custom-built with your exact needs and specifications in mind. 

A Wide Range of Personalization Options 

With thousands of color choices available, your San Franciscan Roaster™ can be tailor-made, in your coffee house’s brand colors, complete with your logo. When a product boasts the “Made in the USA” distinction, people notice. We hold ourselves to a higher standard and want to make our customers proud of their purchase.

"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."

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

By utilizing 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 is essential, but it doesn’t necessarily result in the perfect roast, time and again. 

Sometimes the data might say a roast should be perfect, but your coffee roasting intuition may say otherwise. This is why we designed San Franciscan roasters to allow the roastmaster to intervene when necessary. This allows you to tweak every roast, embracing (and controling) the craft as completely as possible!

Roastmasters must be able to embrace the craft of commercial coffee roasting, and our roasters make that a reality! San Franciscan Roasters lead the way, in keeping the spirit of artistry alive in the world of specialty coffee roasting

At the San Franciscan Roaster Company, we have a saying, don’t fear the craft; embrace it!” People assume that technology can save them from mistakes. But technology can very easily go wrong, when the slightest input errors are made. More often than not, people are afraid to use their own senses to bring correction to a roast.

"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!
