Alfa Laval Hybrid Powder Mixer M15 Powder mixers

Introduction

The Alfa Laval Hybrid Powder Mixer M15 is a mobile dual-stage

inline powder dissolution unit that quickly and efficiently disperses

powders, mixing them with liquids into a homogeneous blend.

Using a single-motor pump, it then transfers the resulting solution

at outlet pressures of up to 5 bar. Versatile, cost effective and easy

to use, this mixer efficiently produces homogeneous products at

high dry matter concentrations and high yields.

Applications

The Hybrid Powder Mixer M15 is an excellent choice for blending

thickeners, stabilizers and emulsifiers into concentrations required

in most hygienic applications in the dairy, beverage and food

industries. It is also capable of producing recombined milk with

more than 50% dry matter.

Benefits

• Fast and homogenous powder dissolving

• A combination of a mobile inline powder-liquid mixer and a

pump

• High dynamic shear, gentle mixing

• Reduced installation, emissions, energy and maintenance

costs

• Reduced total cost of ownership combining the functions of

powder mixing and pumping into a single unit

Standard design

The Alfa Laval Hybrid Powder Mixer M15 is comprised mainly of a

two-stage pump with a rotor-stator as the first stage and as the

second stage. It is also equipped with a funnel and an injector.

The funnel is used to introduction powder through an injector

system, which can be isolated using a hygienic C-ball valve. The

injector pre-blends the powder and the liquid, while at the same

time creating underpressure in the funnel outlet.

The unit is mounted on a stainless-steel frame. The table easily

slides into position on the frame, making it easy to place bags of

powder there during mixing. It also functions as a lid to cover the

funnel when not in use. The liquid inlet is equipped with a sight

glass and a butterfly valve.

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.
