Humic acid drum scraper dryer

Humic acid drum scraper dryerWorking principle
Drum dryer is an internally heated conductive rotary continuous drying equipment. The rotating drum adheres to a certain thickness of material film through its lower material groove, and heat is transported to the inner wall of the drum through pipelines, conducted to the outer wall of the drum, and then transmitted to the material film, causing the moisture in the material film to evaporate and dehydrate, and drying the material containing moisture. The dried material is scraped off the drum surface by a scraper and falls onto a screw conveyor placed below the scraper. The dry material is then collected and packaged by the screw conveyor.

Humic acid drum scraper dryerfeature
1. 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 moisture in the material film on the cylinder wall, with a thermal efficiency of up to 80% -90%.
2. High operational flexibility and wide adaptability. Various drying factors of the adjustable drum dryer. Factors such as the concentration of the feed/thickness of the coating film, temperature of the heating medium, and rotation speed of the drum 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, allowing it to adapt to the drying of various materials and different production requirements.
3. Short drying time. The drying cycle of materials is generally only 10-15 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.
4. High drying rate. Due to the thin film 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 an evaporation intensity of 30-70Kg. H2O/m2. h.

Scope of application
Suitable for drying liquid materials or viscous materials in industries such as chemical, dye, pharmaceutical, food, metallurgy, etc.
