As the name suggests, a destoner will rid your roasted coffee beans of any stones or foreign material that could have been introduced during the roasting process. It's important to remove this foreign matter to avoid costly damage to grinding equipment and maintain the quality of your coffee.

One way of understanding what a coffee destoner does is to think of it as an adjustable vacuum cleaner. The destoner is designed to only be able to move material that is the same density as the roasted coffee beans. Any foreign matter (which will be heavier and more dense than the roasted coffee beans) will drop out leaving you with your delicious, roasted coffee.

Disclaimer: Any modification from the standard design to suit customer's requirements, may occur an additional cost.
