Abstract
Liquid organic material is controllably delivered to a receptacle located in the center of a heated surface capable of horizontally rotating about its central axis. As the heated surface rotates, material deposited within the central receptacle is forced outwardly and across the rotating surface. As the material moves radially, it evaporates into a vapor which is then transported to one or more nozzles. From the nozzles, the vapor is applied to a substrate and condensed. Relative to existing devices and methods, the present invention enables the evaporation of a wider variety of organic liquids, greater reliability in continuous operation, a decrease in maintenance, and a larger and more constant material flow rate.
