Principle

Rotary Drieris a kind of internal rotating drying equipment. Certain thickness of material film adheres to the roller throughtrough. Heat is transferred to the internal wall of the roller through pipes and conducts to the external wall then to materials film, evaporate moisture in materials film so as to dry materials. Dried product scraped out by scraper fitted on the surface of roller, then collects and packs material by auger conveyor.

Feature

1. High thermal efficiency. The principle of heat transfer of rotary drier is heat conduction which heat conducting direction keeps identical with operation cycle. Except cap heat dissipation and radiation loss, all heat energy can be used for evaporating wet materials on the wall of roller. Thermal efficiency could reach 80%-90%.

2. Large operation elasticity and wide application.Various drying factors of the rotary drier can be adjusted, such as density of feeding materials, thickness of materials film, temperature of heating medium, rotating speed of roller etc, which can change drying speed. As these factors have no interrelations with each other, it brings great convenient to dry operation, and makes it applicableto suit various materials and to meet different requirement of production.

3. Short drying period. The drying period of material is normally 10 to 15 seconds, so it is suitable for heat-sensitive material. It can be also working under less pressure condition if it is put in vacuum device.

4. Drying rate is quick. As material film coated on the wall of roller is very thin. Normally thickness is 0.3-1.5 mm, plus heat and mass transfer direction are identical, the evaporation capacity on the surface of film can keep at 15-70kg.H₂O/m2.h.

Application

It is suitable fordrying liquid raw material or sticky material in chemical industry, dyestuff industry, pharmaceutical industry, foodstuff industry, and metallurgy industry and so on.
