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.

Standard design

The Alfa Laval Hybrid Powder Mixer S15 is comprised mainly

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

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

injector. The funnel is used to introduce 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 S15 unit is reduced to basic functions, without table,

frame and frequency converter and therefore has lower

investment costs than the fully equipped Alfa Laval Hybrid

Powder Mixer M15.

Introduction

The Alfa Laval Hybrid Powder Mixer S15 is a stationary 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 S15 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 stationary 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

• Reduced investment cost due to the reduction to basic

functions

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.

Raise process efficiency, product quality and yield while reducing total cost of ownership

with Alfa Laval powder mixers. A combination of pump and powder-dissolving technologies

makes possible quick, efficient powder dispersion, wet and dry ingredient blending,

and the transfer of the homogeneous powder-liquid mixture for onward processing.

A single electric motor drive enables powder mixers to cut energy costs by up to 75%

compared to other powder mixers.

Increase mixing efficiency and energy efficiency while reducing total cost of

ownership

• Boost yield thanks to quick and efficient blending of wet and dry ingredients into a

homogeneous mixture

• Increase process and product flexibility, easily handling various formulations with

different viscosities, densities, and volumes

• Cut process time, emissions and installation, energy, raw material, and maintenance

costs

• Improve process flexibility by leveraging the mixing and cleaning capabilities in a single

unit

• Fast return on investment and low total cost of ownership due to less waste and a more

sustainable use of resources

Alfa Laval powder mixers increase mixing efficiency and productivity while reducing total

cost of ownership. A single electric motor drive enables the high-shear mixers to blend a

wide variety of product formulations.

The mixers draw powder into the unit while simultaneously pumping the resulting powder-

liquid mixture at pressures of more than 4 bar. When used with a rotary jet mixer, the 

powder mixers may also be used as part of an efficient cleaning-in-place (CIP) system.

Powder mixers are available as stationary units and mobile units.

Working principle

Before round pumping or adding any products from upstream

pipe works, ensure that the IM 10 Rotary Jet Mixer is positioned at

the correct level and submerged into the liquid. Four nozzles feed

the liquid, gas or powder into the liquid in the tank. The nozzles

rotate around both the horizontal and vertical axes in a 360°

movement. This three-dimensional jet rotation enables the jets to

reach the entire tank volume, providing fast, efficient mixing of the

injected liquid, gas or powder without requiring batch rotation.

The complete system is built with a circulation loop, enabling

liquid to be pumped from the bottom of the tank and back into the

Rotary Jet Mixer. For faster mixing requirements, several rotary jet

mixers can be installed in series.

Benefits

• Fast, effective liquid mixing performance in tanks

• Efficient gas and powder dispersion

• Can be used as tank cleaning machine

• Handles multiple applications

• Unmatched, cost-effective mixing performance

• Simplified, hygienic design, modest investment

• Optional pre-engineered skid-mounted pump unit available

Standard design

The Alfa Laval IM 10 Rotary Jet Mixer consists of a mixer body,

turbine and nozzles. Compared to traditional systems using

propeller mixers, there is no need for a shaft, seal or gearbox.

Excellent mixing is achieved without the use of baffles or any

batch rotation. Available in four different models (IM 10. IM 15. IM

20. IM 25), these mixers are designed for tank volumes from 100

litres in size and beyond, and they are capable of handling re

circulation flow rates up to 90 m3/h.

Introduction

The Alfa Laval IM 10 Rotary Jet Mixer effectively handles liquid

mixing, gas dispersion, powder mixing, and tank cleaning while

reducing mixing time, energy consumption and costs.

Patented technology based on proven Rotary Jet Head

technology, it provides quick, efficient and uniform mixing without

any batch rotation or the use of baffles. It also ensures greater

process flexibility, making it easy to switch to new product

formulations with diverse viscosities, densities and volumes.

Applications

The IM 10 Rotary Jet Mixer is designed for liquid mixing, gas

dispersion (aeration, deaeration, carbonation), and powder

mixing in process and storage vessels from 1 to 10 m3 in size

across the dairy, food, beverage, brewery, healthcare, home and

personal care, and biotechnology industries.

When the tank is empty, the IM10 also acts as a superb Cleaning

in-Place (CIP) system, saving water, cleaning media and energy

compared to using a spray ball CIP system.
