Floatation Washer with De-Stoner

Product Description

The floatation washer with de-stoner is primarily used in frozen and shelf-stable (canned / jarred) lines. This washer is optimized for sweet corn kernels, de-podded peas and additional dry beans.

Operating Principle

Product first enters the de-stoning system. An infeed chute distributes product evenly onto a water-treated conveyor. The conveyor movement and cleats catch stones, and move them away in the opposite direction of the product. Those then to settle into the bottom of the tank.

Next the product is fed to the washing system. Paddles in the tank create agitation of the water itself. This separates desired product from floating dirt and debris. Unwanted material is channeled away by a cleaning sieve. Product then goes to a vibratory separator to shake off excess water prior to discharge.


This washer is equipped with a water cleaning and recirculation system. This reduces both consumption and waste, even during cleaning.

  • Flotation stone catcher conveyor
