A mobile agricultural product treatment system for cleaning and sorting generally granular agricultural products such as raisins, seeds, nuts, grapes and the like. In an embodiment, a conveyor belt transports agricultural product into an inlet hopper for treatment by the pneumatic cleaning unit. The treated agricultural product is discharged from the pneumatic cleaning unit onto a vibratory sorting unit. The vibratory sorting unit includes several screens arranged in increasing mesh size to sort from smaller to larger agricultural products. The sorted agricultural product is collected by downwardly sloping conduits. In an embodiment, the conduits include a screw conveyor. The conduits feed into a series of vertical screw conveyors which lifts the product up to a high point into a downwardly sloping horizontal conduit. In an embodiment, the discharge from the horizontal conduit is routed through a flexible duct to allow for positioning of collection bins. In an embodiment, a multilayer field drying and transport medium is provided which is retracted after field treatment by a transfer unit. The transfer unit receives the field drying and transport medium onto a retraction spool. The retraction spool includes one or more vertically oriented cutting blades which longitudinally bisect the field drying and transport medium, allowing the agricultural product to free fall into the field collection bin used to feed the stair-step type conveyor unit.
