Dodman manufactures a range of vegetable and fruit de-stoning systems that ensure stones are removed from food produce prior to the washing process. From cyclone de-stoners to economical flume de-stoners, DL has a de-stoning solution to suit a wide range of vegetables and fruits. With our high quality de-stoning and cleaning equipment, stones, clods and other materials which may be present within a crop are removed at the beginning of the vegetable processing line, ensuring a high quality end product.

A unit widely used throughout the industry utilising a well proven principle and incorporating modern techniques to give efficient stone removal. Units remove stones, glass, sand, metal and other foreign bodies.

For removing foreign material from vegetable produce. A simple, efficient and relatively inexpensive combination of units for separating stones, sand, glass, metal, wood and foreign materials from peas, beans and similar materials.


The flume system can remove heavy contaminants such as glass, stones and nails from produce. It can also be located after blanching on the process line so that light pumice type stones are removed. This system is particularly effective for garden peas and pulses.


This process is used for pre & post washing for the removal of heavy contaminants & also more specifically the removal of any glass fragments. The system features an automated contaminant discharge and is suited to produce such as wheat, rice and pulses.


We have systems that can combine stone removal & elevation of produce within the food processing plant. This system elevates product, whilst at the same time removes stones & clods. Particularly suited to root crops

  • Each unit may be used singularly or as a combination for effective product cleaning. The Floatation Washer unit uses water to allow small lighter foreign material such as leaves, chips of wood, polyethene/polystyrene etc. to float to the surface thus separating from the heavier vegetable produce.
  • The Stone Remover is designed on a flotation principle Product is transported over a series of rifle plates where denser than product material is deposited.
  • An efficient combination of units for separating stones, sand, glass, metal, wood and other foreign matter from peas, beans and similar materials.
  • Flotation washer and de stoner designed to allow use singularly or in combination
  • The flotation tank uses careful design and water flows to separate buoyant material from the raw material. Water is recirculated to the flotation tank through a filter box to collect debris.
  • The destoning race uses a series of riffle plates to trap dense matter whilst the more buoyant raw material passes over in the water flow.
  • The riffle plates are lifted periodically to allow dense debris to collected and removed from the system.
  • A pumped, recirculating system with automated level control minimises water use
