The newest machine in the Giesen collection is the W140A, developed in 2017 to meet the wishes of our clients. With the capacity to roast 140 kg green beans per batch (max. 560 kg/h) the W140A is well equipped for industrial purposes.
Complete automatic roasting process
The Giesen W140A coffee roaster is a completely automated coffee roaster. The Green Coffee Conveyorwith weighing cells weighs your beans and transports them to the machine. The coffee beans will be roasted up to 140 kg per batch, which is more than twice as much as the W60A. The roast profile is completely adjustable with drum speedcontrol 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 together with the Air-conditioning option for the cooling sieve will speed up the cooling process even more.
Add an emergency generator to keep downtime due to power failure to a minimum.
Control panel with touch screen
The roasting process can be monitored and programmed with the control panel, using the Roast Profile System. Due to the size of the W140A the control panel is developed completely anew to suit the new coffee roaster. Implemented in the panel are two screens, one for the roast profiling system and one to control the coffee roaster.
Roast recipes can be 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. An action is 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 control panel is easy to operate due to the touch screen that gives you the possibility to control and programme the temperature, the power, the fanspeed and the drum speed.
