Operating principle

The agitators are installed inside the tank either centrally with current deflectors (baffles), or offset so that the position itself prevents the rotation of the mixed product. The rotation of the propeller makes the fluid flow to the bottom and then up to the surface of the product along the walls of the tank. The effect is enhanced if the bottom of the tank is curved.
