high quality rotary dryer
Product Application of rotary dryer
Drum drying equipment is a kind of rotating continuous drying
equipment with internal heating conducting-style. Certain thickness
of materials film attach to the drum from material liquid vessel
under the drum. Heat is transferred to the internal wall of the
cylinder through pipes and then to the external wall and to
materials film, to evaporate the moisture in materials film so as
to
dry materials. Dried products are then scraped off by the blade
fitted on the surface of the cylinder, fall down to the spiral
conveyor under the blade, and are conveyed, collected and packed.
Features
1. High heat efficiency. The principle of heat transfer of the
cylinder dryer is heat conduction and the conducting direction
keeps identical in the whole operation circle. Except heat loss of
end cover and radiation loss, all heat can be used for
evaporation of wet materials on the wall the cylinder. The
efficiency can reach 70-80%.
2. Large operation elasticity and wide application. Various drying
factors of the dryer can be adjusted, such as concentration of
feeding liquid/thickness of material film, temperature of heating
medium, rotating speed of the drum etc. which can change drying
speed of the under dryer. As these factors have no interrelations
each other, it brings great convenience to dry operation and
makes it applicable to dry various materials and to meet different
requirements of production.
3. Short drying period. The drying period of materials is normally
10 to 300 seconds, so it is suitable for heat-sensitive
materials. It also can be pressure reducing operated if it is put
in vacuum vessel.
