Stronghold S7X

More Power, Same Size

S7 X, at 850g batch size, has more power through the all-new Drum Heater, providing controllable conductive heat and reliable replication consistency.
X-lens opens a new world of understanding the roast, with increased response time and precision unmatched by traditional probes.

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.

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.

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.
