complete solution

The Giesen W45 coffee roaster can be operated completely automatically. The standard working steps are automated to ensure a fast, easy and efficient roasting process. The green beans are being poured automatically into the hopper and will subsequently be released into the roasting drum. 

After the roast, the roasted coffee beans will be poured into the cooling sieve. The cooling fan has a high cooling capacity of 3 minutes to cool down a whole batch of 45 kg coffee beans. At the same time, during the cooling phase, new green beans can be released into the drum for the next roast. This ensures the productivity and efficiency of the total roasting process.

Save & replay roast recipes

The roasting process itself can be monitored and programmed via the control tower system. This is the well known Roast Profile System, that Giesen Coffee Roasters uses. Proven recipes and roast profiles can be saved into the system and replayed for selected batches. In this way, it is easy to roast different coffee types, each with their own settings and duration, for the optimal stable end result that meets the original quality every time again. 

The control tower system is easy to operate via a touchscreen where the temperature, power, fan speed and drum speed can be adjusted. All parameters are visible on the screen and every adjustment can be controlled, even up to the physical under pressure in the roasting drum.

Low noise & easy to maintain

The Giesen W45A coffee roaster has a cast iron double walled drum with high-performance bearings. The whole machine is equipped with low noise fans and all parts are easy to clean and maintain. Additionally, the roaster works with an external cyclone to collect the chaff of the roasted beans. The standard heat resistant colours are black or silver grey as we consider those a suitable finishing touch for this highly industrial coffee roaster. Upon request, it is possible to customize the colour of the coffee roaster into every existing RAL code. 

Another advantage of our W45A is that a remote support router is included. Which ensures you of faster and easier support and the latest updates.
