Heating Chamber: The part of the machine where the flour is exposed to heat. It may use electric, gas, or steam heating methods.
Stirring Mechanism: To ensure even roasting, the machine usually has a stirring or agitating system that constantly moves the flour.
Temperature Control: Allows precise control of the roasting temperature to achieve the desired level of roast.
Cooling System: After roasting, the flour needs to be cooled quickly to stop the cooking process and preserve its quality.
Conveyor System: In larger machines, a conveyor belt may be used to move the flour through different stages of roasting.
Ventilation: Proper ventilation is essential to manage the heat and any fumes produced during the roasting process.
