ABSTRACT:
A dryer system for a liquid cleaning apparatus has a dehumidifier to remove vapors, droplets of liquid cleaning agent and recirculate dry gas onto workpieces moving on a conveyor. The dryer is particularly useful for removing solvents and restricts solvents escaping from the cleaning apparatus. The dryer has an enclosed tunnel from an enclosed liquid containing tank, a conveyor passes from the tank through the tunnel towards an exit. A dehumidifier is associated with the tunnel to remove vapor and liquid particles from atmosphere above the tank and in the tunnel, and supplies dry gas to assist in drying workpieces leaving the tank and passing through the tunnel.
