FEATURES
Robust. Savvy. Dynamic.
Sivetz Roasting Machines was founded in 1974 by Michael Sivetz, an engineer and chemist who had a vision for designing a more effective and consistent coffee roaster. His outspoken passion for quality coffee helped lay the groundwork for the specialty coffee movement that we enjoy today.
SIT/BT and Automated Profiling
Roasting coffee using inlet temperature (IT) rather than gas valve settings gives your coffee a much more precise roasting environment. Measuring bean temperature (BT) to determine roast progress, the SRM15’s profiling features can achieve repeatable, precise results, even allowing for fan speed profiling and fully automated roast profiling.
SRM15 FeaturES
Precision over variability
Most production roasters on the market today provide controls for changing heat variables without directly measuring heat input. With the SRM15, roasters can profile inlet temperature (IT) to manipulate the roast curve, opening new doors for precision and repeatability. On other roasters, input temperature is not singular since the conductive heat of the drum, burner percentage, convective air flow, and radiant heat all contribute to heat changes.
The power of IT roasting
With Sivetz roasting, air inlet temperature (IT) is controlled throughout the roast, precisely steering bean temperature (BT). This hugely downplays other variables like BBP and ambient temperature. The difference is similar to comparing sous vide to a gas stove. By setting a desired temperature, the environment is accurately controlled, rather than juggling burner percentage and other variables to control temperature.
Fully automated profiling
Using automated profiling, a roaster can dial in the best profile for the coffee and achieve precise, repeatable results. These profiles can be closely replicated by other SRM15 roasters, enabling maximum roast profile consistency among multiple locations, perfect for retail chains. With the variables of BBP, ambient temperature and roaster response time largely downplayed, repeatable results can be achieved by less experienced staff once a roast is dialed in.
Built on a simple, easy to maintain mode
The original Sivetz revolutionized the way coffee was roasted, inspiring many other roasters to use convective air flow as the primary heat input due to its consistency and effectiveness.
Today, the SRM15 still only uses one moving part while providing new features and profiling controls, allowing the roaster to be serviced by end users.
