Working principle

The two-stage inline Alfa Laval Hybrid Powder Mixer S15 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 for tanks 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 to 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.

When the mixing is completed, the Hybrid Powder Mixer may

be used as a discharge pump, or as a Cleaning-in-Place (CIP)

recirculation pump to clean the tank when used in combination

with an Alfa Laval Rotary Jet Mixer.
