Abstract

An extrusion system for separating soil entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of soiled water, to allow soil to settle by gravity, and to allow clarified water collection at the top. A diffuser suspended within the tank converts the flow of soiled water into multiple transverse flows to avoid churning the settled soil. A sensor detects the level of settled soil reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated soil from the bottom of the settling tank.
