To stir up and mix the substances held inside a retort, a blade is used, of a shape corresponding to that of the retort itself. Inside the blade there is a conduit, connected to outer devices for the admission of gas, and provided with a series of apertures, directed towards the inner part of the retort, for the discharge of the gas.
