In all machine sizes, Primo roasters use specially designed paddle mechanisms to move the coffee in the drum efficiently, creating an even roast throughout the beans. Our variable rotation speed allows different batch sizes to be roasted on the same machine. Our drum, airflow, and paddles keep the beans movement consistent inside the drum. Our precise hot airflow roast the beans with as little drum contact as possible. Primo roaster’s features create a steady bean pattern and an unvarying, quality roast.
The high processing quality of the Primo PRI series is partly thanks to its premium design. The machines roast and cool simultaneously, with individual exhaust for cooling and roasting air. We use automated gas control with infrared ceramic burner technology for ease of use and consistent batch quality control. Our two stage temperature controller with automatic thermal control comes standard on all Primo roasters.
