The device is used to mix and degas a flowable mass (5), in particular a filler-containing casting resin. It is provided with a cylindrically constructed, evacuatable container (1), the container axis (2) of which is oriented essentially vertically. Guided along the container axis (2), it also contains a shaft (12) that holds agitating elements (8, 21). The container (1) is divided into an upper storage container (4) for holding the mass (5) to be degassed, a lower buffer space (19) for holding the degassed mass (20), as well as a pass-through container (6) with a degassing system arranged between storage container (4) and buffer space (19), in which degassing system the mass (5) to be degassed is guided in the form of thin layers. The thin layer degassing system contains at least two conically constructed run-off surfaces (15, 16) offset axially relative to each other. The run-off surfaces are angled in opposing directions. Because of this, the mass (5) to be degassed gravimetrically flows between the shaft (12) and the wall of the container (1) first from the inside to the outside, and then from the outside to the inside. This long flowing path significantly improves the degassing of the mass (5). The stripping elements (17, 18) arranged just above the run-off surfaces (15, 16) and constructed as agitating arms cause the thin layers formed from the mass (5) to be smoothed and mixed, and in this way additionally improve the degassing and mixing of the mass (5).
