A process for drying solvent containing material is disclosed. The solvent containing material is passed through a drying chamber containing an inert gas. Inert gas is introduced into at least one lock chamber preceding and/or following the drying chamber. An annular flow of inert gas is produced in the lock chamber. A minor amount of the inert gas required for drying the material is jetted into the lock chamber proximate to the inlet and/or outlet opening of the drying chamber and a mixture of inert gas and sucked-in external air being discharged from the lock chamber in the peripheral region of the annular flow. The major portion of the inert gas is introduced directly into the drying chamber. An apparatus for practicing the invention is also disclosed. |
