Proper Coffee Bar
World's First
Triple Heat System
Stronghold's patented tower drum design technology
allows for even agitation of the coffees as you manage
convective, radiant, and conductive heat applications.
This triple heat system results in optimal roasting approach.
Conductive heat
Agitating blade pushes the coffees from center of the drum
to the far edges of the drum.
Conductive heat is evenly and efficiently applied to the coffees.
Radiant heat
Halogen's radiant heat truly differentiates our Smart Roasters
from our competitors. Penetrating more energy
through multiple layers of the coffees, you can now
more evenly develop your coffee inside and out.
Convective heat
Hot air circulates throughout the drum and
transfers heat to every bean for even heat distribution
With X-Series technology's new drum heater,
you can now independently manage conductive heat
on top of the existing convective and radiant heat controls.
You can now express even more complex and fine-tuned taste
and aroma experience.
Roastware,
where the smart roasting is
Spawned from the research of many dedicated
engineers, chemists, and roasting professionals,
the embedded Roastware is ready
to simplify your roasting experience and needs.
Program roasting
By selecting the coffees' origin, processing method,
and desired roast level, Roastware will factor in
all the information and run optimized roasts for you.
Manual roasting
Manual roasting mode gives precise control over
conductive, convective, and radiant heat, allowing you
to define your roast like never before.
Profile auto-save
Reliable roasting data is readily available through
integration of advanced sensing technology
and the embedded software. Saved roasting profile
can be easily managed and analyzed.
Auto-replication
Our algorithm takes replication to the next level
by automatically reading and reacting to the changes
in external factors and making heat adjustments to
arrive at a perfect replication beyond human capabilities.
Roasting Made Easy
Cooling Tray
