SUS2205 Industrial Vacuum Rake Dryer 4000L For Sensitive Materials

Its working principle relies primarily on the combined effects of vacuum and heating. The main unit consists of a horizontal cylindrical shell with a jacket, inside which a rake-type agitator driven by a motor is installed. During operation, after the material is fed into the cylinder, steam or hot water is circulated through the jacket to indirectly heat the material, while a vacuum pump simultaneously removes the evaporated moisture (water or organic solvent) in real time. As the rakes rotate slowly, they continuously turn and mix the material, constantly renewing the heating surface area, thereby significantly enhancing heat transfer efficiency and preventing material clumping. 

The core advantage of this device lies in: 

High adaptability: capable of handling highly viscous and easily agglomerated materials, and can meet various process requirements by adjusting the rake speed and vacuum level. 

High thermal efficiency: materials boil and evaporate under vacuum, resulting in minimal heat loss and easy solvent recovery. 

Product quality is stable: low-temperature operation and uniform mixing effectively prevent material overheating and denaturation, resulting in a final product with low moisture content and consistent crystal structure. Additionally, the equipment features excellent sealing performance, preventing dust dispersion and meeting GMP cleanroom production requirements. 

Overall,Rake dryers are an ideal choice for tackling complex drying challenges, particularly suitable for organic solvent recovery and the purification of heat-sensitive products.
