Stronghold's patented technology

Vertical tower drum and triple heating system

Triple heating system: Independent control of three heat sources for precise heat transfer: convection, radiation, and conduction.

• Insulated vertical tower drum : 5-layer drum structure to maximize thermal stability during roasting.

• Bean movement: The speed of bean movement is controlled to allow for better energy distribution.

• Ceramic coating: Protection against bean residue for the interior surface
• 10.1” Touchscreen: User-friendly interface for monitoring and controlling roasting profiles

Intelligence meets perfect roasting

• Roast profile management: Control, monitor, and verify the key factors during and after roasting.

• Programming mode: Let the roaster roast according to pre-programmed roasting profiles optimized by roasting professionals.

• Automatic Replication Mode: Replicate the profiles stored in the roastware with unsurpassed accuracy and consistency to save time and effort.

Using PID control, our proprietary heat control algorithm makes heat adjustments at the micro level to react immediately to deviations from the stored roasting profile.
