Manufacturer of drum scraper dryersummary:

HGThe series drum dryer is an internally heated conductive rotary continuous drying equipment. The rotating drum adheres to a thick film of material through its lower groove, and heat is transported to the inner wall of the barrel through the pipeline, conducted to the outer wall of the barrel, and then transmitted to the film of the barrel, causing the humidity in the film to evaporate, dehumidify, and dry the material containing moisture. The dried material is scraped off the surface of the drum by the device, and then transported to the screw conveyor below the scraper. The dried material is then collected and packaged by the screw conveyor. Suitable for industries such as food, chemical, and pharmaceutical.

Product features:

1.High thermal efficiency, due to the drum drying mechanism, the heat transfer mechanism belongs to thermal conduction, and the conduction direction is maintained throughout the entire operation process. Except for the heat dissipation and radiation loss of the cover, all the other heat is used for the evaporation of the moisture content of the bucket film, and the thermal efficiency can reach80%-90%.

2.The operation has great flexibility and wide practicality, and can adjust many drying factors of the drum dryer. Factors such as the concentration of the feed, the thickness of the coating film, the temperature of the heating medium, and the rotational speed of the drum can all change the drying rate 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.

3.The drying time is short, and the drying cycle of the material is generally only10-15Second, more suitable for heat sensitive materials. If the dryer is set in a vacuum chamber, it can operate under reduced pressure conditions.

4.The drying speed is high, and due to the thin film applied to the barrel wall, it is generally0.3 -1.5mmAnd the direction of heat and mass transfer is *, and the surface of the material film can be maintained30 -70kg. H2O/m2.hThe evaporation rate.

Manufacturer of drum scraper dryerworking principle:

Drum dryer is an internal heating and conduction type rotary drying equipment. Wet materials obtain heat transferred through thermal conduction on the outer wall of the drum, remove moisture, and achieve the required moisture content. The heat is transferred from the inner wall of the cylinder to the outer wall, and then passes through the material film. It has high thermal efficiency and can be operated continuously, so it is widely used for drying liquid or strip materials, and is more suitable for paste and viscous materials.

Structural form:

It can be divided into two forms: single tube scraper dryer and double tube plate dryer. Additionally, it can be divided into two forms based on operating pressure: atmospheric pressure scraper dryer and pressure reducing scraper dryer.

Suitable materials:

1.The chemical, mining, metallurgical and other industries dry large particles and materials with high specific gravity, such as mining, blast furnace slag, coal, metal powder, phosphate fertilizer, and ammonium sulfate.
2.Drying of powders and granular materials with special requirements, such as: HPFoaming agent, distiller's residue, light calcium carbonate, activated clay, magnetic powder, graphite, drug residue.
3.Materials that require low-temperature drying and require continuous drying in large quantities.
