    The inlet and outlet ducts can be placed in alternating pattern so that both concurrent flow and counter flow of the air can be achieved in one dryer. A continuous flow dryer cannot be used as a stand alone machine but needs to be integrated in a larger system consisting of the dryer several tempering bins and conveying equipment (Figure 12).
