VDMC = Vertical Drop Multi Cleaner aspirator

 The V.D.M.C. is a high capacity six pass aspirator. The cleaning process occurs as the product enters the aspiration columns and is contacted by an air wash which removes light fines, straw, hulls, etc. The concentrated product free-falls through the aspiration column, which by its design expands the product stream allowing for more efficient cleaning. The aspirated light materials are pulled through the aspiration column into the liftings chamber to settle out in the closed circuit model, or discharged to an outside collection system in the open circuit design.
