Abstract

Mixing device for mixing at least a substance and a fluid. The device comprises a container (12, 16) with a compartment (18), a first feeding member (20) to feed the substance from above into the compartment (18), a second feeding member (22) to feed the fluid into the compartment (18), and an outlet pipe (24), through which a mixture of the substance and the fluid emerges from the lower part of the compartment (18). The compartment (18) comprises at least a first part (17) having a gradual widening in section from the bottom towards the top. The second feeding member (22) is arranged in an intermediate zone between the first feeding member (20) and the outlet pipe (24) and is able to feed the fluid into the compartment (18) at a determinate pressure, so as to create a vortical motion upwards of the fluid in the first part (17), in a direction opposite that of the feed of the substance into the compartment (18). <IMAGE>
