Detailed Product Description

drying machine, drying machinery, scratch board drier, ISO9001

Features:

 High thermal efficiency. The principle of heat transter 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 cyinder 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 inter-relations 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 10to 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 0.3to 1.5 mm, plus directions heat and mass transmitting are identical, the evaporation strength on the surface of the film can keep at30~70kg..H2O/m2.h.
