Another object of the invention is to provide an improved method for the efficient removal of water moisture at accelerated rates to the desired content and minimize denaturation of the protein content in addition to the cleaning the whole seeds, beans, of undesireable, foreign, materials, in a one step operational procedure. 

A still further object of the invention is to provide a new and novel means for the accelerated drying of the naturally occurring oilseeds, beans, to the desired water moisture content with controlled heat penetration of the oilseeds utilizing cocurrent contact of the solids with heated gases for movement of the material through the flash drying unit to achieve a product material dried to the desired moisture content and cleaned of undesireable and foreign materials as compared to current practice in this art for the particular oilseeds. 

It is a still further object of the invention to provide a new and unique method for exposing material surfaces to the cocurrent heat source to effect efficient evaporation of the water moisture from the solids material under controlled flow conditions in equipment specifically suited and designed for the particular material with no externally or internally moving mechanisms in the cleaning and accelerated drying units.
