ABSTRACT:
An industrial dryer for drying industrial materials, such as sludge, salt water, brines and the like. A transition plate which is slotted in a manner to cause hot gases flowing toward and through the slots to be immediately transformed into a free standing vortex on the downstream side of the transition plate. The vortex operates on the wet materials and the hot gases. Structure is provided to collect the water vapor created by the drying action. In a first embodiment, hot gases are created by the operation of a blower which directs air under pressure through a heater, then into and through the slotted transition plate. In a second embodiment, a resonating engine is used as a source of hot gases.
