<p>A mixing and stirring device for a cylindrical tank, containing mash, wine, juice, syrup or concentrates, is fitted with a vertical shaft with an annular spiral-shaped scoop on radial carrier arms. The scoop runs at a small distance from the inside wall and produces a descending flow along the scoop blades and an ascending flow inside them. The blades can also be hollow and joined to the hollow shaft for the circulation of a heating or cooling medium. This device achieves a homogeneous stirring and mixing action independent of the filling level even at slow speeds.</p> |
