| STEAM TUBE DRYER |
| The SWENSON Steam
Tube Dryer is a rotating cylinder containing rows of
steam tubes, arranged in concentric circles, and
extending the full length of the cylinder. The
tubes are designed to transfer heat from the steam to the
material being dried and may be supplied with or without
fins, according to the design specifications. Together with radial flights, the tubes serve to agitate the material and to provide uniform mixing and drying. The dried product is discharged through discharge chutes. Steam is introduced into the tubes through a manifold located at the discharge end of the cylinder. The manifold is connected to a rotary steam joint which admits the steam and continuously drains the condensate. The thermal efficiency of the dryer is very high and heat loss through the cylinder wall is minimal, because the steam tubes are completely enclosed by the dryer. SWENSON Steam Tube Dryers are designed and manufactured in accordance with the ASME Code, Section VIII, for unfired pressure vessels. Steam tube dryers may range in size from 12" to 144" in diameter and from 8' to 90' in length. Water tube coolers are similar in appearance to steam tube dryers. The cooling water enters the cooler at the discharge end and leaves at the feed end.
