What kind of power supply does a roaster of this size typically require?

Units in this class commonly operate on a three-phase electrical supply for motors and controls, with specific voltage requirements varying by model and region. Buyers should confirm exact electrical specifications with the seller.

Is it possible to roast different types of coffee beans with this equipment?

Yes, roasters of this type are designed to handle various types of green coffee beans, allowing for diverse roast profiles. The control over process air and combustion air facilitates adaptability.

What maintenance is generally required for a used coffee roaster?

Regular maintenance typically includes cleaning the roasting drum, cooler, and cyclone, checking moving parts and bearings, and inspecting gas lines and electrical connections. Specific schedules depend on usage.

How does the heating system work to ensure even roasting?

Many roasters, including those with patented systems like the STA, use specially designed burners and airflow regulation to achieve uniform heat distribution across the coffee beans, crucial for consistent colour and flavour development.

What safety features are commonly found on these roasters?

Standard safety features often include water safety devices for the roasting drum and cooler, automatic extraction for chaff, and an electronic control board with general electrical safety devices.
