W140A Coffee Roaster

Our Giesen W140A coffee roaster is completely automated. The Green Coffee Conveyor with weighing cells, weighs your beans and transports them to the machine. The coffee beans can be roasted up to 140 kg per batch, which is more than twice as much as the W60A.

Completely adjustable

The roast profile is completely adjustable with drum speed control and airflow control. The low stationary burner makes it possible to control the temperature very accurately. The optional pellet press will press your coffee chaff into a easy to dispose disk. And the water injection option for the drum will speed up the cooling process even more. For additional security, you can add an emergency generator to keep downtime due to power failure to a minimum.

save & replay roast recipes

The roasting process is monitored and programmed with the control panel, using the Giesen Profiler Due to the size of the W140A the control panel is to suit the new coffee roaster. To clarify: Implemented in the panel are two screens, one for the roast profiling system and one to control the coffee roaster.

Roast recipes are saved into the roast profiling system as roast profile and replayed, each with their own settings or always the same settings for the same high-quality outcome. You can adjust every setting at every moment during roasting or add actions. Actions are programmed in advance. When a certain value is reached, a certain action will follow. For instance, your beans reach 120 degrees, the temperature drops with 30 degrees.


The W140A coffee roaster measures 1,26 meter width, 3 meters length and 2,2 meters height. So with all the extra equipment, the roaster will need about 64 m2.

The W140A coffee roaster has a partially cast iron drum with high- performance bearings. It can be equipped with the following new optional features; water injection in the drum in the cooling sieve to speed up the cooling process. As well as The green coffee conveyor with weighing cells that transports your beans automatically to the machine or with a pellet press to compactly dispose of your coffee chaff.  

Standard equipment like the low stationary burner, low noise fans and drum speed control are also featured in this coffee roaster. Additionally, the roaster works with an external cyclone with an automatic sluice to collect the chaff.
