Abstract
A desolventizer for processing solvent-wet solid material may include a thermal recirculation loop to increase thermal performance. In some examples, the desolventizer includes a housing, an ejector, and a vent. The housing contains a first tray and a second tray vertically elevated above the first tray to define a processing space. The ejector has an inlet located between the first tray and the second tray and an outlet also located between the first tray and the second tray. The vent has an inlet located between the first tray and the second tray. In operation, the ejector can draw gas from the processing space via the inlet and discharge the gas through the outlet back into the processing space, creating a recirculation loop.
