ABSTRACT:
Apparatus and processes for removing volatile components from a composition utilize a dryer having an inlet chamber and a plurality of channels. A flow restriction is disposed immediately upstream of the inlet of each channel with respect to a direction of flow of the composition through the dryer. The process includes the step of heating the composition at a location upstream of the flow restriction to a temperature above the flashing temperature of at least one of the components at a pressure of the channel inlet and applying a pressure to the heated composition to avoid such flashing. The process further includes the step of passing the pressurized, heated composition through the dryer inlet chamber, the flow restriction, and through the channels.
