Abstract: A method and apparatus for removing moisture from a drying gas serving for the drying of solids, in particular granular plastics (10), which gas is dried in an adsorption drying agent after passing through the substance, then heated and finally conducted again through the substance to be dried. A first bed (32a) of drying agent in which the drying agent is utilized until complete saturation is connected in series with a following second bed (32b) of drying agent in which the drying agent is utilized only up to partial saturation. Behind the second bed (32b) of drying agent, a partial stream of the drying gas is conducted through a third bed (32c) of drying agent which has been regenerated in the meantime, while the other partial stream is conducted into the drying container 12, bypassing the third bed (32c) of drying agent. A fourth bed (32d) of drying agent is regenerated in each case. The four beds of drying agent can be exchanged for each other.

Abstract: Non-aqueous solvents are removed from a web material, e.g., paper, by contacting the material with a condensable, heat transfer vapor, e.g. saturated steam, in countercurrent fashion. The heat transfer vapor is employed in the process in amounts of at least 50% by weight of the solvent to be removed. The process allows effective and efficient total removal and recovery of the solvent without damage to the web material. The condensable heat transfer vapor, as well as being the source of energy for evaporating the solvent, acts as a solvent vapor carrier. Condensation of the mixture in a recovery apparatus, e.g., condenser or still, allows easy recovery of the solvent.

Abstract: The hot air dryer for plastic materials is disclosed. Three desiccant cartridges are carried on a rotatable turret and each cartridge is indexed successively from a process air station to a regeneration station and then to a cool down station. At each station, the cartridges are clamped between sets of upper and lower conduit fittings to provide a closed air flow path. A clamp spring acts on a lower conduit carrier to raise the cartridges against the set of upper conduit fittings to a clamped or closed position. The clamping actuator including a motor driven lead screw acts on the carrier to retract it against the resistance of the clamp spring to lower the turret and hence the cartridges away from the set of upper fittings to a stop position and the carrier is further retracted to separate the set of lower conduit fittings from the lower end of the cartridges thereby opening the clamp and the air flow path through the cartridges.
