The pre-soak unit or wet hopper is suitable for floating and sinking products. 

The pre-soak unit is mainly used for delicate products such as sweet potatoes or for products that require a longer pre-soak time to removed dried soil from the product. The unit has been designed to process floating and sinking products. The speed of the outfeed belt is infinitely adjustable using a controller. This enables the outfeed capacity to be set.  An auger chute is mounted underneath the unit to remove sinking particles of e.g. clay and sand. 

A pusher mounted at the rear of the pre-soak unit pushes floating products towards the outfeed belt so they are not left behind in the unit. As an option, the unit can be fitted with a discharge drum so the floating products can be removed regularly. The speed of this discharge drum can be adjusted to set the soaking time and outfeed capacity. 

A tipper or supply belt can be used to feed products into the unit.
