Abstract

A fluid tight container 11 defines a conical internal cavity 35, and has an upper feed pipe 12 and a lower outlet opening 14. A cylindrical stirrer 15 is wholly enclosed in the cavity, and is driven in a circular oscillating manner by an external eccentric mechanism coupled to an extension of the stirrer. This arrangement makes it possible to mix products of high viscosity and gas without excessive heating and leakage, by virtue of the exclusive use of static fluid-tightness.
