Rotary steam tube dryers dry at a lower temperature, are resilient and can handle significant upsets. Dryers that use steam as a heat source instead of hot air tend to operate with greater thermal efficiency. In addition, the installed cost of steam tube dryers is roughly the same as direct fired dryers.
In Steam Rotary Dryers steam is used as heating medium: steam is conveyed inside a series of tubes. The heat transfer occurs from the tubes wall to the product by radiation and conduction even if the temperature of metal surfaces is generally low, as a result of the saturation temperature of steam which depends on its inlet pressure.

Steam tubes are designed to transfer heat from steam to the material being dried. Thus being the most energy efficient dryer.
Steam dryers are like regular dryers, but they offer an option that introduces steam into the dryer at ideal times. This may help reduce wrinkles, static and odor. Steam can be used on just-washed, wet loads for extra wrinkle protection or dry, lightly-worn clothes to refresh them without having to wash.
Conventional dryers apply heat to wet clothes to evaporate the moisture, or turn the liquid water into a gas. This resultant gas is, of course, steam. So why design a dryer to apply more steam to clothes? Even though steam is a byproduct of drying, applying steam at the right times to wet clothes or dry clothes has advantages.
