HG series (single drum, double drum) drum dryer

The drum scraper dryer is an internally heated conductive rotary continuous drying equipment. The rotating drum is adhered to a thick film through its lower chute, and heat is transported to the inner wall of the drum through pipes, conducted to the outer wall of the drum, and then transmitted to the film, causing the humidity in the film to evaporate, dehumidify, and dry the material containing moisture. The dried material is removed from the drum by a scraper installed on the surface of the drum and transported to a screw conveyor placed below the scraper. The dry material is then collected and packaged by the screw conveyor.

● High thermal efficiency. Due to the fact that the heat transfer mechanism of the drum dryer belongs to thermal conduction, the direction of heat transfer remains consistent throughout the entire operation cycle. Except for cover heat dissipation and thermal radiation loss, all other heat is used for the evaporation of the wet film of the drum material, and the thermal efficiency can reach 80% -90%.

● High operational flexibility and wide applicability. Various drying factors of the adjustable drum dryer. Factors such as feed concentration, coating film thickness, heating medium temperature, and drum rotation speed can all affect the drying efficiency of the drum dryer, and these factors are not interrelated. This brings great convenience to the drum drying operation, enabling it to adapt to the drying of various materials and meet different production requirements.

Short drying time. The drying cycle of materials is generally only 10-300 seconds, which is suitable for heat sensitive materials. If the drum dryer is set in a vacuum chamber, it can operate under reduced pressure conditions.

● High drying rate. Due to the thin film of coating applied to the cylinder wall, generally between 0.3-1.5mm, and the consistent direction of heat and mass transfer, the surface of the film can maintain a capacity of 20-70kg H2O/m2? H has strong evaporation.

The HG series drum scraper dryer is widely used in industries such as food, chemical, and pharmaceutical for the production and drying of viscous and paste like materials.
