Coffee-Tech incorporate the most advanced roasting technology in the world to prepare coffee beans to the correct degree of roasting. The solar roasters heats the beans with “Infrared Radiation” heaters in a revolving perforated drum. The drum transfers secondary heat to the beans via Conduction. At specific stages during the roasting process air is pulsed through the beans to create a fluidised bed to enhance the heat transfer via Thermo syhon and Convection.
The solar roasters combines traditional “Drum roasting” and “Fluidised bed roasting”· processes in order to achieve consistent uniformity, resulting in full aroma and flavour. The process utilises no less than four heat transfer methods to carefully roast your coffee to perfection.
