Innovative Quality Variable Profile Roaster from Buhler

This roaster offers exactly what customers need to produce top-quality coffee. An innovative and easy-to-use PLC control system ensures constant quality during production but also retains the ability to influence the processing when necessary. Optimized parameters can be saved in the machine's memory and re-used.
The machine is made of stainless steel and other high-quality materials which provide superior hygiene and make cleaning easy. This roaster proves that durability and a modern design can be combined. 

Plug and Play

The roaster becomes a plug-and-play machine by the combination of separate cooling and heating fans which allow to roast and cool at the same time with the included cyclone. Hot air is the best choice to ensure a uniform roast, because of the homogenous heat transfer.

Two-Step Burner

The variable drum speed of the roasting chamber and the two-step burner always deliver the best conditions for the product no matter if the beans are heavy and small at the beginning of the process or if they have already become lighter towards the end of the roast.

Can You Say Helicoidal?

The helicoidal blades powered by a variable drum speed drive offer a perfect blending and an optimal heat exchange at any time of the process. Moreover, the ergonomically designed roaster provides maximum safety.

This roaster was designed to provide small and medium-sized companies with a flexible high-quality solution.

The sophisticated design of the roasting machine plus modern process technology ensures a high-quality coffee product that is uniformly roasted from the surface to the core of every single coffee bean.

The coffee and the hot air temperature, as well as the roasting time per batch, is permanently monitored via the touch screen. The machines' design features and insulating materials reduce inertia and heat loss to a minimum, which impacts positively on working environments and fuel consumption.
