Screw destoner is designed for pre-washing and stoning of root vegetables.

It consists of a rectangular hopper into which water is supplied and a vertical pipe with a discharge conveyor screw.

HOW IT WORKS

The product to be destoned is inserted into the water hopper and lifted gently with the water into the pipe by means of the screw rotation. Rotational movement lifts the product and allows water to drain off the sides of the screw. Heavy parts that water cannot pick up remain on the bottom of the hopper. The pure product (without stones) comes from the top of the screw.

BENEFITS:

• gentle to the product 
• washing and destoning in one compact machine
• simple operation and maintenance.
• Made of high quality stainless steel
• adjustable screw speed using a frequency converter
