makes roasting quick and easy

This model is perfect for a middle large roastery. The Giesen W15A coffee roaster has a capacity of 500 gr. up to 15 kg per batch. Like all Giesen Coffee Roasters, there is the possibility to roast and cool at the same time. 


The W15A is known to be a very accurately controllable coffee roaster. Because of this, it is still very suitable for larger batches of specialty coffee. With the fast cooling motor, it is possible to quickly cool your roasted coffee beans. This decreases the total production time. 

Add an external cyclone to your W15A and start roasting non-stop. A cyclone collects the chaffs that comes from the roasted beans. Because of this, the beans that come into the cooling sieve are separated from the chaffs and after cooling down can be processed immediately. You don’t have to clean the chaffs out of the roaster between roasting, because the cyclone is external. It is also easier to clean the coffee roaster when using an external cyclone. 


Congratulations, your business is expanding! Happy customers that love your coffee=more cups of coffee sold=increased capacity= more roasting= more lifting of heavy sacks. 

To reduce manual handling tasks which return on a daily basis, we introduce our Green Coffee Conveyor with scale. So no more lifting and moving heavy sacks  above your head, repeated bending and scooping! The green coffee conveyor automatically transports your green coffee to the hopper. If you are looking for a completely automated coffee roasting process a green coffee conveyor is a must. 

Most importantly, the speed of which the daily chores can be performed is much higher, providing better working economies as well as reduced risk. The beans are transported through the delivery line by using suction. The green coffee conveyor is available with or without weighing cells.
