The '''Air Impingement Dryers''' are typically utilised in the coating sections of board machines. The systems are custom designed for your process and can be either gas or steam heated. | The '''Air Impingement Dryers''' or [[Impingement Dryers]] are typically utilised in the coating sections of board machines.

Hot air is made to impinge in a plug flow manner on a moving loosely formed bed of wet feed. Moisture evaporates as the material traverses along the length of the bed and is rendered dry at the discharge end. Humid air is continuously exhausted. The dryer is employed for wet crystals which are very fragile as well for wet performed feeds which are not suitable for the normal belt dryer operation. | Hot air is made to impinge in a plug flow manner on a moving loosely formed bed of wet feed.
