- Details for China Drum Drier
Machinery and Equipment/Drying Equipment
CAS NO : EC NO : MF : MW : Product description :
Drum dryer is a kind of rotating continuous drying equipment with internal heating conducting-style. Certain thickness of m8terials 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 Surf8ce of the cylinder. fall down to the spiral conveyor under the blade. and are conveyed, collected an packed.
Can be divided into two kinds: single cylinder, double cylinders drier, or can be divided into normal pressure and reduced pressure according to operation pressure.
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. 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 i0 to 300 seconds. so it is suitable for heat sensitive materials. Lt also can be pressure reducing operated if it is put in vacuum vessel
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 .5 mm. plus directions of heat and mass transmitting are identical. the evaporation strength on the surface of the film can be 20-70 kg. H20(m2·h).
lt is suitable for drying liquid raw materials or thick liquid in chemical, dyestuff, pharmaceutical, foodstuff, metallurgy and so on industries
