Cylinder dryer is a kind of rotating continuous drying equipment
with internal heating conducting-style. Certain thickness of
materials film theres to the lower trough of materials under the
rotating cylinder.Heat is transferred to the internal wall of the
cylinder through pipes and misfired again to the external wall and
to materials film,to evaporate and damnify moisture in materials
film so as to dry materials. Dried therials are then scraped out by
the blade fitted on the surface of the cylinder, fall down to the
spiral conveyor under the blade, and are conveyed, lected and
packed.
It is suitable for drying liquid raw materials or thick liquid in
chemical industry, dyestuff industry, pharmaceutical
industry,foodstuff stry, metallurgy industry and so on.

High thermal efficiency. The principle of heat transfer of the
cylinder dryer is heat conduction whose conducting direction keeps
identical whole operation circle. Except heat dissipation of end
cover and radiation loss, all heat can be used for evaporation of
wet materials on the wall the cylinder. Thermal deficiency can
reach 80-90%.
Large operation elasticity and wide application. Various drying
factors of the cylinder dryer can be adjusted, such as density of
feeding aerials/thickness of materials film, temperature of heating
medium,rotating speed of
the cylinder etc.which can change drying speed of the under
dryer.As these factors have no interrelations each other,it brings
about great convenience to dry operation.and makes it applicable to
ing of various materials and to meet different requirement of
production.
Short drying period.The drying period of materials is normally 10
to 15 seconds,so it is suitable for heat-sensitive materials.It can
be also rated under less pressure condition if it is put in vacuum.
Fast drying rate.As film of materials coated on the wall of the
cylinder is very thin. Normally, thickness is 0.3 to 1.5 mm,plus
directions heat and mass transmitting are identical, the
evaporation strength on the surface of the film can keep at 15-70
kg.H2O/m2.h. |
