What types of products can this de-stoner process?

This type of de-stoner is typically used for products like potatoes, carrots, other root vegetables, pulses, and some fruits where heavier foreign objects need to be removed.

How does a screw-type de-stoner work?

Product is fed into a water bath where a rotating screw agitates the mixture. Heavier stones and debris sink and are conveyed out by the screw, while the lighter product floats and is discharged separately.

What maintenance is typically required for this equipment?

Routine maintenance commonly involves checking and replacing wear parts such as the drive belt (as noted for this unit), bearings, and seals. Regular cleaning is also essential for hygiene.

Can this unit be integrated into an existing processing line?

Yes, its substantial size and design suggest it is intended for integration into industrial processing lines, typically positioned after washing and before further sorting or processing stages.

What is the significance of stainless steel construction?

Stainless steel construction is crucial in food processing for its hygiene properties, ease of cleaning, and resistance to corrosion from water and various food products, ensuring compliance with food safety standards.

SKU: 000492

Price: Contact seller for price

Built for robust performance in demanding processing environments, the Stainless Steel De-stoner One is a powerful screw-type de-stoner engineered for reliable, high-volume operation. Its durable stainless steel construction ensures long-lasting use while maintaining strict hygiene standards—ideal for industrial food processing applications. Designed with a large infeed clearance of 1300 mm x 200 mm, this machine easily handles substantial product flow, feeding into a screw mechanism approximately 550 mm in diameter for effective separation. The screw-driven system delivers consistent de-stoning performance while minimizing product damage and waste. With overall dimensions of 1750 mm x 1800 mm x 3700 mm, the Stainless Steel De-stoner One offers a substantial processing capacity within a solid, industrial footprint—perfect for integration into existing production lines. Important Note: This unit is currently missing its drive belt, and will require replacement or fitting before operation.
