Our quality line of screw de-stoner machines is ideal for use with all types of root crops. By integrating this system into your facility’s processing line, you can significantly reduce the potential for wear and tear to related equipment in the production line. Comprised of a reception hopper outfitted with a vertical transport screw that is driven by a reduction gearbox, this de-stoning machine allows the produced to enter a circular hopper filled with water for the de-stoning process. Heavy particles fall back into the circular hopper base where they can be collected for removal. Clean products are then transported off the machine. A sieve is also included for separating earth and stone. Designed for simple and effective use, this de-stoning machine ensures that products are not damaged. Production capacity is determined by the size of the product.
