The machine for Individualists

The roasters in the UG series brilliantly combine advanced technology with an attractive, retro design that takes you back to a different era of coffee roasting. Our UG 15, 22 and 45 roasters are made by hand by PROBAT's subsidiary KIRSCH + MAUSSER. They are seen by coffee roasters as machines for individualists who place special demands on their roasted products.

Type-UG15/22/45 roasters

The UG series roasters cover roast capacities of 12, 22, and 45kg per batch. Each machine is made individually by hand upon request, with extraordinary precision. 

With all UG machines, the volume flow of the roasting air can be individually adjusted to the respective roasting phase by means of a converter on the roasting fan. 

In addition, the traditional "aroma wheel" offers the possibility of completely suppressing the volume flow in the drum.Uniform mixing of coffee beans in the drum
