The Machine for special demands

The G45 occupies a special position in the product portfolio of the PROBAT subsidiary KIRSCH + MAUSSER: Manufactured in the stylish design of the smaller UG series roasting machines, extended functionalities come already as standard. It also stands out due to its very flexible batch capacity. With a drum volume between 25 and 55 kg, it is exactly the right choice for roasteries who on the one hand reach production limits with their UG series roasters and on the other hand want to continue processing smaller batches.
