Title
(DE) DESOLVENTIERER-TOASTER MIT KONVEKTIVER STROMRÜCKFÜHRUNG
(EN) DESOLVENTIZER TOASTER WITH CONVECTIVE CURRENT RECYCLE
(FR) DÉSOLVANTISEUR-TOASTEUR À RECYCLAGE DE COURANT PAR CONVECTION
Abstract
(EN) 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.
(FR) L'invention concerne un désolvantiseur destiné à traiter un matériau solide mouillé par un solvant pouvant comprendre une boucle de recirculation thermique destinée à accroître les performances thermiques. Dans certains exemples, le désolvantiseur comprend un boîtier, un éjecteur et un évent. Le boîtier contient un premier plateau et un deuxième plateau surélevé verticalement au-dessus du premier plateau pour définir un espace de traitement. L'éjecteur comporte une entrée située entre le premier plateau et le deuxième plateau et une sortie également située entre le premier plateau et le deuxième plateau. L'évent comprend une entrée située entre le premier plateau et le deuxième plateau. En fonctionnement, l'éjecteur peut aspirer le gaz provenant de l'espace de traitement par l'intermédiaire de l'entrée et évacuer le gaz à travers la sortie vers l'espace de traitement, créant ainsi une boucle de recirculation.
