ABSTRACT:
A method of removing solvents from a paste includes introducing a heated paste into a channel of a dryer under pressure selected so as to avoid flashing of any of the components of the paste. At the inlet of the channel, the pressure is dropped, resulting in the flashing of selected components of the paste. As the paste advances through the channel heat is applied to the paste. Vapor liberated during the flashing acts as a motive force to convey the paste along the channel. The resulting concentrate is collected at an outlet of the channel.
