American-Made Roasters for the Artisan Coffee Roaster

At The San Franciscan Roaster Company, we use the highest quality materials and components to create roasters that last a lifetime. They are built of 100% schedule 40 steel and contain no cast iron, making them extremely durable. Schedule 40 steel is more conductive than stainless steel, making it more responsive to heat controls during the roasting process.

 Every single roaster is meticulously handcrafted to suit your specifications.

San Franciscan Roasters are all designed and built in the United States, using only American-made parts. We are a private company, not beholden to shareholders or third parties who want to cut costs. We simply don't compromise on quality when we build your roaster. Our philosophy is that we build every roaster in the way that we would want it built for ourselves.

Advanced Components and Classic, Handmade Beauty

In order to make the coffee roasting process as efficient and eco-friendly as possible, the SF25 is fitted with an afterburner. This burns up any smoke and odor created from the roasting process or left with. The afterburner and chaff collector are combined in a separate cylinder, which is fitted behind the roaster for ease of maintenance. Much like our other roasters, the SF25 is compatible with most data-logging programs.

The roaster also comes equipped with variable drum rotation speed, a hot air damper, and a variable speed hot-air fan. Only high-quality American-made motors, sprockets and bearings are used in construction. The gas and electric parts of the SF25’s are also American-made, guaranteeing quality and longevity.
