Jet Drying System

An integral part of the system is a Vacu Jet Dryer—a serpentine tube-type evaporator, which is typically 8 to 80 m long with a diameter of 8 to 50 millimeters. The inlet of the evaporator is connected to the feeding system, which supplies the liquid material diluted with a solvent if necessary. In the 

The majority of liquid heating and solvent evaporation takes place inside the evaporator, which is heated indirectly by steam or hot oil. Typically, the wall temperature is kept 20 to 30 C higher than the solvent boiling point. A significant portion of the remaining solvent is evaporated when the material expands adiabatically in the product collection section, which is held under reduced pressure. 

A powdery product is obtained in cases where solid particles in a slurry feed do not dissolve even at the solvent boiling point. In the case of viscous liquids, which contain only a small amount of the solvent and therefore do 

One of the preferable applications of the Vacu Jet Drying system is the separation of solids from solvent slurry or solution with simultaneous recovery 

Hazardous solvents are claimed to be safely removed with superior recovery.
