  • Triple Heat System - Independent control over three heat sources for precise heat transfer control: convection, radiation and conduction.

  • Insulated Vertical Tower Drum - 5-layered drum structure to maximize thermal stability during roast.

  • Bean Agitation -  Bean agitation speed controlled for better command over energy distribution 

  • Ceramic Coating - Internal surface protected from coffee residue over time.

  • 10.1" Touch Screen - User-friendly interface to monitor and control the roast profile.

The Stronghold S7 allows precise control over all aspects of what makes a particular coffee truly special. I believe Stronghold’s technology offers the ability to be more consistent, which is what separates great roasters from the ordinary

Glyph Supply Co, Singapore

It gives an option to have really freshly roasted beans which takes a really short time to replicate while they have a coffee. We also save half the labour for the roaster and the person can do something else which makes it really efficient

PRODUCTIVITY

  • Accurate temperature sensing and fast consecutive roasting.

  • Fast cooling speed returns the roasted coffee to room temperature within 90 seconds after it drops.

  • Unmatched productivity within its class.

EFFICIENCY

  • Save your labors costs with automated replication roasting; anyone can reproduce the same exact taste batch after batch.

  • Unparalleled auto replication roasting quality by using 7 temperature sensors.

  • Save your coffee cost by replicating roast profiles time and time again with precision.

ENVIRONMENT FRIENDLY

  • Protect the environment by using 100% electric roaster.

  • With the absence of gas combustion, there are no emissions and it's safer to install/operate.

Morten Munchow, Founder of Coffee Mind

The Stronghold X-Series is the most advanced equipment I have seen from an experimentation point of view and being able to play with even infrared, conduction and convection independently have made it possible for the roast master to isolate these factors for the first time ever.

So this being available for the community on their production roasters already (if they have a Stronghold X-Series) is seriously next level of technology

Arseniy Kuznetsov, World Roasting Champion 2019

What I find the most important attributes in coffee taste is sweetness and balance, this approach helped me to win the World Roasting Championship. In my opinion, variations in conductive heat would help to achieve it, and Stronghold X-Series made that possible for me.

I like to work precisely to adjust and make the ideal roasting profile. Once I am Happy with it, I can just share that profile and allow others to use autoreplication and achieve the same result I am absolutely sure in
