Abstract
A system is provided for de-gassing a material. The system includes a vessel and a material distributor. The vessel has an internal chamber in which a vacuum can be maintained. The material distributor is located inside the internal chamber and is adapted to distribute the material to be degassed as a thin film along at least one wall of the vessel in such a way that exposure of the thin film to vacuum within the internal chamber causes entrained air or other gasses from the material to be withdrawn from the thin film. Also provided is a method for degassing a material. Preferably, a material distributor is inserted into a vessel where degassing of a material is to be performed. The material distributor can comprise an inlet for the material to be degassed, a scaling lip, a film-forming lip, and a material distribution cavity. The sealing lip is adapted to sealingly engage at least one wall of the vessel. The film-forming lip is spaced apart from the sealing lip. The material distribution cavity is defined between the sealing and film-forming lips, and is in fluid communication with the inlet. When the sealing lip sealingly engages the wall(s) of the vessel, the film-forming lip is positioned with respect to the wall(s) in such a way that the material to be degassed exits the material distribution cavity by passing as a thin film between the film-forming lip and the wall(s).
