The water bath is typically used for the first few rounds of the harvest. DryMac Water Baths are designed to efficiently sort good Wet Nut In Shell (WNIS) from last seasons old, dry nuts.
The fresh WNIS will sink to the bottom of the Water Bath and be picked up by a partially submerged conveyor.
Any old, dried nuts that have been picked up and included with the new harvest will float and be carried away in the water out flow from the bath.
An important factor in the flotation sorting process is the removal of the free water accumulated on the NIS during the water bath.
The conveyor used to carry the good WNIS uses a perforated modular belt to allow water to pass off the nut and through the belt. This important feature ensures that free water is reduced before the nuts enter the drying process.
DryMac also produce an Airknife Dryer that can be connected to the Water Bath conveyor to almost eliminate free water.
