Design and dimensions of a mechanical defoamer. This paper presents a newly developed powerful mechanical defoamer which exploits centrifugal force and, thanks to circular channels, also Coriolis force for destruction of foam. It is incorporated into containers such that the expelled foam concentrate is deflected by the lid without producing fresh foam. Model experiments with three geometrically similar but different sized laboratory models led to dimensionaltheoretically formulated process‐relations of the defoamer for various material systems (five chemical foamers, two biological substrates). Such process‐relations represent a reliable basis for design and dimensions of the defoamer presented, on the one hand, and permit determination of an „intermediate characteristic”, having the dimensions of acceleration, which represents the mechanical degradability of the foam.
