XDT Series Drum Dryer
Drum dryer 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 material 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. ]
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
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
requirement 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
4.Fast drying rate. As film of materials coated on the wall of the
cylinder is very thin. Normal, thickness is 0.3 to 1.5mm, plus
directions of heat and mass transmitting are identical, the
evaporation strength on the surface of the film can be 20-70 kg.H2O/m2.h.
It is suitable for drying liquid raw materials or thick liquid in
chemical, dyestuff, pharmaceutical, foodstuff, metallurgy and so on
