Gravitational destoner for potatoes
Efficiently remove unwanted stones and debris from your potato and vegetable processing lines with this robust gravitational destoner, ensuring clean and pristine end products.

Separates Stones and Impurities from Produce
The Gravitational Destoner F63 from Boema S.p.A. is engineered to tackle the challenges of impurity removal in food and agricultural processing. This equipment features an overturned cone with an inner rotor that creates turbulence, allowing dense foreign matter like stones and soil to settle at the bottom. An integrated screw elevator continuously evacuates these impurities, ensuring uninterrupted operation and protection for subsequent processing stages. Ideal for potatoes and vegetables, this machine fits seamlessly into lines for producing potato chips, French fries, starch, and various diced and pureed vegetables. Designed for continuous processing, the F63 can handle significant volumes, supporting high-capacity food processing environments. Its simple yet robust construction facilitates easy maintenance and cleaning, while its continuous operation mode maximizes throughput. The device’s efficient separation mechanism minimizes downtime and optimizes product purity, making it a vital component in ensuring quality in potato and vegetable processing applications.
