Airflow Controlled Roasting (semi-heat blast)

Our advanced roasting design combines the traditional radiant heat of a drum roaster with the ability to control the airflow and convection heat through the drum for exceptional results. Our roasters can perform as a traditional drum roaster and with the added airflow control even beginners can deliver uniform heat to the beans for superior results.

Maximum efficiency

High thermal efficiency of the drum structure is designed to enable the roasting time and 10 part heater unit to implement the results of the rich roasted flavor and aroma that can not be shop-class experience from the existing 1KG roster.

Precise airflow control

By utilizing the damper switch you can precisely control the airflow through the roaster to create the desired roasts and aromas.

Rapid cooling system

Rapid cooling of the roasted coffee is a very important factor in maintaining the taste and flavor of your roast. PROASTER utilizes a powerful blowing motor that can cool the beans in under three minutes.

Safety system

If the power goes out or the exhaust blower fails then the safety system is designed to close the gas valve. Additionally, if the roasting temperature reaches the upper limit then the safety system will turn off the gas and power supply.
