Jiutian® scraper drum dryer is a continuous indirect-heating drying machine with steam as the heating medium to ensure that the dried product is highly clean. The material film of a certain thickness is attached to the drum from the material liquid container under the drum. The raw materials are evenly distributed on the heated surface of the drum. The heat is transferred to the inner wall of the drum through the pipe, and then to the outer wall and the material film, so that the material film is of water evaporates. The material can be completely dried after one rotation of the drying cylinder, and the sheeting material automatically falls into the discharge port under the action of the scraper device, complete unloading, simple operation, and high drying efficiency.
Scraper drum dryer is suitable for drying liquid or viscous materials in chemical, dye, pharmaceutical, food, metallurgy and other industries, such as beer yeast, potassium humate, sodium humate, gelatin, etc.
Features
1. High thermal efficiency: The thermal efficiency can be as high as 90%.
2. Fast drying: the drying process only takes 10-15 seconds. Therefore, the drum dryer can be used for drying heat-sensitive materials.
3. Clean dried product: The machine uses steam as a heat source for indirect drying to ensure the cleanliness of the materials.
4. Uniform drying: The heat transfer direction and coefficient of the entire drum surface are the same. Wet materials can be evenly spread on the surface of the drum and dried evenly.
Materials:Suitable for drying liquid or viscous materials, such as brewer's yeast, gelatin, potassium humate, sodium humate, etc.
Application:Drying viscous and pasty materials such as spent brewers yeast and chemical slurries.

The drum scraper dryer uses indirect conduction heating with steam to evaporate moisture from materials. The drying cylinder is a hollow metal drum with a highly polished outer surface. Driven by a gear transmission system, it rotates at an adjustable speed.
The slurry is preheated to about 50 °C and pumped into the dipping tank, where the lower part of the drum is immersed 60–80 mm, forming a uniform thin film on its surface. With steam pressure at 0.15–0.3 MPa, heat transfers through the drum wall, causing moisture to evaporate and be discharged by an axial flow fan. After one full rotation, the dried material is scraped off by a blade and collected at the discharge port.
