ABSTRACT:
A desolventizing system for removing solvent from a quantity of solvent-laden particles such as flakes comprises first and second desolventizer units, each having an inlet port for receiving solvent-laden particles, an outlet port for discharging at least partially desolventized particles, and a solvent vapor port. A solvent trap is connected between the outlet port of the first desolventizer through a first airlock, and to the inlet port of the second desolventizer unit. Particles entering the solvent trap through the first airlock are conveyed to the inlet port of the second desolventizer. The second desolventizer unit has an airlock connected to the outlet port of the second desolventizer unit. The solvent trap has a vent preferably in the upper part of the trap for connection to a vacuum source that maintains a partial vacuum within both the solvent trap and the second desolventizer unit allowing liquid solvent and water permeating particles within the second desolventizer unit to vaporize efficiently at a relatively low temperature. Solvent vaporized in each desolventizer unit can be drawn out through the solvent vapor port of the desolventizer unit for further processing and later reuse.
