Protect your beans with this portable destoner

Constructed with stainless steel and able to run up to 900 lbs an hour, this portable destoner removes stones and other dense particles such as green beans and quakers for light and medium roasts.

How destoning works

Using the process of fluidization, the destoner separates stones and other objects that are denser than the beans. The beans float across a bed of air that is not strong enough to lift objects that are denser than the beans.

Variable airflow controls

Adjusting the airflow can fine-tune the separation and change the rate which the beans flow over the bed. In general, less air will slow the rate of the beans and separate out smaller stones and other objects that are close to the density of the beans. As a general rule, it is better to run the destoner as slow as possible 

A dust collection system is included. 

  • Standard hopper 15 lbs
  • Optional hopper 25 lbs

You will be amazed how easy it is to clean the Destoner!

Hand Fill

You can hand fill the Destoner mounted on a bench or on a stand. The large funnel makes it easy to fill without spilling the beans.

Stands are available to raise the beans to any level

Do you want to load beans into a brute container, a portable bin, a blender or a grinder? We can custom make a stand to meet your needs. Stands are available with casters or forklift brackets.

Funnel Extension

The funnel extension increases the funnel capacity to up to 20 pounds of roasted beans.

Dust Collection System

All destoners come with a de-dusting outlet. For normal operation, it can be connected to a ShopVac for dust collection. We offer several different collection systems for commercial operations.
