Wahal portable batch type in tank mixer is highly useful for batch preparation. The in tank homogenizers comprises of a single set of working head, i.e., a rotor-stator where the centrifugal forces created by the rotor sucks the material in the working heads and throwing it outwards to the stator walls, where the shearing takes place ensuring highly narrow and efficient droplet size distribution and evenly dissolved solids. Hence it becomes impossible for the material to miss from passing from the inlet to the outlet without being subjected mechanical shear action. The stator is available with perforations of different size and shapes. This gives the advantage to the machine to adopt different processing operations.
