Improved thermal stability
To achieve even further temperature stability, the S8X comes with a redirected internal airflow pathways while maintaining cooler temperatures surrounding the roaster itself.
Variable blower speed to control airflow
S8X allows adjustments of the blower to fine-tune your profiles via airflow management. Enjoy even more refined expression of taste and aroma in your coffees.
Batch size: 1.5kg to 4.5kg
The batch capacity is ideal for a business to grow to be a small production roastery and to the next level.
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.
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.
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 transfer heat to every bean for even heat distribution.

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 code 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.
