Continuous Seal Steam Tube Dryers

The Louisville Continuous Seal Steam Tube Dryer offers tremendous advantages for solvent extraction or drying in an inert gas atmosphere. The CS unit's design permits material to be processed in a positive or negative pressure atmosphere and alleviates product and gas leakage into or out of the dryer.

The dryer is operated as a counterflow unit. Air moves in the opposite direction of material flow. Sweep gas flow is used only to exhaust vapor and other gases created by the heating process, not to dry material. Low sweep gas velocity through the dryer vastly reduces the amount of product entrained in the exhaust stream.

During solvent extraction, this not only means significant savings in the size and cost of recovery equipment, but simplifies dust collection requirements and reduces the cost of equipment required to handle the task.
