Steam Tube Dryer. Steam tube dryer is one of the indirect heated rotary dryers, which contains rotating shell, rows of steam tubes arranged in concentric circles and extended throughout the length of the dryer. Steam tubes are designed to transfer heat from steam to the material being dried. This is one of the most energy efficient dryers.

The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving. The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights ...

Apr 09, 2019 The introduction of steam from the steam tube and the discharge of condensed water directly affect the efficiency of the dryer. The traditional steam tube rotary dryer or steam calciner has a steam drum at one end and the steam heat exchange tubes in the dryer are connected. The steam drum is steam-distributed and hydrophobic by a steam drum.

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. Saturated steam is preferred type of medium, since heat is transferred to product by steam condensing and negligible effect is given by superheated steam.

May 08, 2019 The steam rotary dryer is equipped with a steam heating pipe in the conventional rotary dryer. The heating pipe runs through the whole dryer and rotates with the cylinder. The material entering the rotary cylinder is lifted and stirred by the heating pipe in the rotating drum, and dried by the heat provided by the heating pipe.
