50-2500L 6RMP Rotocone Vacuum Dryer Machine for Food Additives and Heat-Sensitive Materials

The Rotocone Vacuum Dryer operates by transferring heat energy through a sealed jacket containing hot water, low-pressure steam, or thermal oil. As the tank rotates slowly at 6 RPM, materials are continuously mixed and flipped, ensuring uniform heat transfer from the inner wall surface. Under vacuum conditions, surface moisture evaporates rapidly due to reduced vapor pressure, with evaporated solvents efficiently removed by the vacuum pump. This continuous process of internal moisture migration, surface evaporation, and vapor removal achieves efficient low-temperature drying in minimal time.
