Technical introduction

Drum scraper dryer is a kind of internal heating conduction type rotary constant drying equipment. Rotary drum pass through its lower chute. There is a material model. Heat is sent to inner drum, outer drum and material model one by one through pipeline. Then the moisture of material model is evaporated and dehydrated. Materials containing moisture are dried. Dried materials are sent to screw conveyor by draw-knife installed on drum surface. Dry materials are collected and packed by screw conveyor. 


High heat efficiency: heat transfer mechanism in rotary drum dryer belongs to heat conduction. Heat transfer direction keeps the same in the whole operation process. Except the heat dissipation of cap and thermal radiation, the rest heat is used for evaporation of material moisture. Thermal efficiency can reach to 80% to 90%.
2. High flexible operation; wide applications; it can adjust various drying elements of rotary drum dryer such as feed density, material model thickness, heat media temperature and rotary speed. All these elements can affect drying efficiency. There is no involvement among these elements, which brings much convenience to the operation of rotary drum dryer. As a result, the drum dryer can adapt to drying and output requirement of various materials.
3. Shorter drying time: generally, the drying cycle of materials is 10 to 300 seconds. It can be applied to thermal sensitive materials. if the rotary drum dryer is set in a vacuum device, the dryer can be operated in a pressure reducing circumstance.
4. Large drying rate: because the material model on drum is very thin. Generally, its thickness is 0.3 to 1.5 mm. The direction of heat and mass transfer are the same. The evaporation strength of materials model can be kept at 20-70kg•H2O/m2•h.

Working principle

HG series rotary scraper dryer is widely used in food, chemistry and medication industry for drying and pelletizing of sticky and paste materials.
