Alfa Laval Hybrid Powder Mixer

Mixing and pumping both wet and dry ingredients into a homogenous blend can - depending on viscosity - require up to four separate electric motors, consuming a lot of energy. The Alfa Laval Hybrid Powder Mixer can accomplish the same result using only a single motor drive, including efficient mixing in the associated production vessel, when used in combination with the Alfa Laval Rotary Jet Mixer.

The powder mixer combines pump and powder dissolving technologies in a single versatile unit, thus reducing installation costs. It is capable of drawing powder into the unit while simultaneously pumping the resulting process liquid at pressures up to 4 bar, making the need for a separate discharge pump obsolete. It effectively pre-blends the powder and liquid before the mixture enters the high-shear stage, which contributes to fast and effective dissolution.

While other inline powder mixers create mechanical shear in a small area, the device creates high dynamic shear in several different steps, requiring less energy to ensure complete dissolution of the powder. The product can also be used as part of an efficient cleaning-in-place (CIP) system. It is said to feature low power consumption, providing up to 50% energy savings; simplified service due to fewer components; and fast and homogenous powder mixing at high dry matter concentration.
