When you go from a 15-kilogram to a 90-kilogram roaster you won’t need a new destoner. It is designed to adjust to almost any roaster. Many customers move them from one roaster to another depending on their needs. The hopper is adjustable in height and many widths are available.

After you roast, you will find the stones in a small drawer at the bottom of the hopper.

The Destoner can be used to remove green beans from a dark roast. It often will catch them from a light roast as well. It is the only destoner that makes that claim. That is clear evidence that it is the best destoner for removing dense particles that are close to the density of a roasted bean.

As with all fluid-bed destoners there are no adjustment when you change roast. 

Open the cooler, then the beans will flow into the hopper. The destoner will sense the beans and start destoning. When all the beans have cleared it will stop and wait for the next roast.
