Features of the coffee destoner for coffee beans

Using coffee beans that still contain foreign objects such as stones or metal pieces can lead to a decline in coffee quality and damage to the coffee grinder. Foreign object contamination can also pose a threat to consumer safety and undermine credibility. As a result, it can lead to lower customer satisfaction and a negative impact on your brand image.

It can handle both green and roasted beans, and the air shutter prevents dust from scattering. The processing capacity is up to 240 kg/h for green beans and 120 kg/h for roasted beans.
