Alfa Laval Hybrid Powder Mixer

The Alfa Laval Hybrid Powder Mixer is a patented hygienic unit that uses a single standard motor to disperse powders into liquids quickly and efficiently, and then pump the combined solution. By combining pump and powder dissolving technologies, this versatile, easy-to-use mixer produces homogeneous products at high productivity while delivering significant energy savings. It is available in either mobile or stationary configurations.

Models

  • S15 Stationary Unit
  • M15 Mobile Unit
Applications

The mixer is an excellent choice for use in a wide range of dairy, beverage, and food powder mixing applications. The Hybrid Powder Mixer is a great solution for applications like incorporating thickeners and stabilizers like pectin and xanthan and emulsifiers in the concentrations required in most applications. It is also capable of producing recombined milk with more than 50% dry matter.

Working Principle

The Alfa Laval Hybrid Powder Mixer is a patented hygienic mobile unit that both disperses powders into liquids quickly and efficiently and pumps the resulting solution at outlet pressures of up to ~72.5 psi (5 barg), all using a single motor. This versatile, easy-to-use mixer produces homogeneous products at high dry matter concentrations and high productivity.

The Alfa Laval Hybrid Powder Mixer is comprised of a two stage pump with one rotor-stator stage and one pump stage. The unit is fitted with a single motor and a frequency converter. A funnel is used for introduction of powder through an injector system which can be isolated using a sanitary C-Ball valve. The construction is mounted on a stainless steel frame and the liquid inlet is equipped with a sight glass and a butterfly valve.
