Working principle

The two-stage inline Alfa Laval Hybrid Powder Mixer M15 is

typically integrated into a circulation loop connected to a batch

tank.

After adding liquid ingredients to the tank, the Hybrid Powder

Mixer circulates the liquid over the tank. To provide additional

high-efficiency mixing, tank with volumes larger than 1 – 2 m³,

installing an Alfa Laval Rotary Jet Mixer is highly recommended.

When adding powder to the liquid, the powder is added through

the funnel. The valve under the funnel is opened. The injector

positioned under the valve creates an underpressure in the funnel

outlet, drawing the powder into the rotor-stator and pre-blending

the products. The rotor/stator (single rings) creates the main

shear, dynamically and efficiently blending powder and liquid into

a homogeneous mixture.

The pump impeller in the second stage creates the final shear

and transfers the powder-liquid mixture into the tank under high

pressure. A portion of the powder-liquid mixture is sent through

the injector back to stage one. This way, the liquid flow in the

injector creates the underpressure in the funnel outlet, which

enables the dynamic suction of the powder into the liquid.
