ABSTRACT:
Disclosed is a method and apparatus for drying granular solids. A heated gas stream is directed through the volume of solids followed by a cooling gas stream. The method varies from conventional drying techniques by the alteration of the timing of the introduction of the cooling stream and by the use of sensible heat contained in the solids to supply heat of vaporization. The method yields improved energy efficiency and shorter drying times. The apparatus exhibits improved efficiency in carrying out the method of the invention than is possible using conventional equipment.
