The chief causes of inefficiency in waste‐heat tunnel driers are (1) the cold bottom in the upper half of tunnels and (2) the hot air which enters the tunnels immediately goes to the top and does not return to the bottom but passes over the top of the ware and emerges at the receiving end of drier only partially saturated. A method is shown of insuring a hot bottom throughout the tunnel and of recirculating the air in the tunnel by means of small fans cooperating with steel baffles on the end of every thud ear, these baffles registering with beams across the top of the tunnel and with pilasters on the sides, thus dividing the tunnel into compartments, with alternately up and down circulation through the ware.
