The Alfa Laval 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.

Effective mixing, reduced mixing time in multiple applications

• Fast, effective liquid mixing performance in tanks

• Efficient gas and powder dispersion

• Can be used as tank cleaning machine

• Unmatched, cost-effective mixing performance

• Simplified, hygienic design, modest investment

The Alfa Laval jet mixer is designed for liquid mixing, gas dispersion

(aeration, deaeration, carbonation), and powder mixing in process and

storage vessels across the dairy, food, beverage, brewery, healthcare,

home and personal care and biotechnology industries. When the tank is

empty, the jet mixer also acts as a superb Cleaning-in-Place (CIP) system,

saving water, cleaning media and energy compared to using a spray ball

CIP system.

Working principle

The unique twin-inlet, double-chamber MicroMerge™ design

improves both operating efficiency and economics. MicroMerge

makes it possible to combine high-intensity dispersion (in the

upper chamber) with a preset contact time (in the lower

chamber).

With two separate inlets – one at the top and one at the bottom

it is possible to feed oil directly into the dispersion section, and

then gradually into the mixing section, as required.

The majority of the dispersion takes place in the top part of the

mixer. Dispersion requires power and the greater the diameter of

the vessel the more power is required. An upper part with a

smaller diameter is therefore advantageous. In the bottom part of

the mixer, highly turbulent, low-shear mixing is used to bring the

dispersed chemicals into contact with all the oil being treated, in a

volume large enough to provide sufficient contact time.

Design

Alfa Laval MX mixers are available in four sizes. Depending on the

capacity required and the duties involved, each size has specific

top and bottom volumes. The type and size of the rotors also vary

according to the specific capacity and the task for which they are

required.

All MX mixers are made of acid-proof steel and have single

mechanical seals. The special oiler provided is fitted with

protection against dry running, and a bottom bearing can be

replaced from the outside without having to remove the agitator.

Fixed-speed operation is standard, but variable speed operation

is available as an option, and is recommended for further

optimization of performance and flexibility.

Introduction

Alfa Laval MX mixers are specially designed to meet the specific

mixing requirements of the fats and oils industry. MX mixers are

ideal for important process stages such as degumming, acid

conditioning and neutralization.

Application

Fats and oils refining.

Benefits

• MX mixers are suitable for use in a wide variety of mixing

activities, including operating under more delicate mixing

conditions.

• Mixing can be done as flexibly as possible, and is easy to

optimize.

• Added advantage of preventing emulsions from forming

Working principle

An impeller with radial blades installed inside the tank rotates

due to the torque from the magnetic coupling. The rotation of

the impeller mixes the fluid inside the tank. The unique design

of the Alfa Laval magnetic coupling ensures the levitation of

the impeller at all times. This enables dry-running and

complete drainability of process fluids from the tank possible.

This ensures highly efficient mixing down to the last drop and,

subsequently, maximum yield. It also enables the free flow of

CIP liquid and steam around all parts of the mixer, thereby

ensuring thorough cleaning. Impeller levitation also eliminates

axial wear.

Available versions

• Impeller with male/female bearing

• Impeller complete, with drive unit

• Impeller prepared for Speed Sensor

Benefits

• Maximum process efficiency, minimal product loss

• Optimal flow with higher efficiency and less energy

consumption

• Mixing down to the last drop for maximum yield due to low

agitation and dry-running capability

• Optimized Cleaning-in-Place (CIP) due to full drainability

• Minimized downtime due to ease of maintenance

Standard design

The Alfa Laval LeviMag UltraPure consists of a detachable

drive unit, levitating impeller unit with radial blades, seals,

ceramic bearings and magnetic coupling, weld plate and

connections. It is available in five sizes, with mixing speeds

ranging from 10 rpm up to 800 rpm.

Introduction

The Alfa Laval LeviMag® UltraPure is an aseptic magnetic

mixer that uses a patented levitating impeller and advanced

design to mix down to the last drop and maximize product

yield.

Compact, energy-efficient and easy to maintain, it provides

dry-running capabilities and efficient mixing at low speeds,

which ensures gentle product treatment, as well as at high

speeds for high-intensity mixing. This provides greater

process flexibility to handle a wide range of fluid types and

mixing duties.

Its open design and low-speed rotation during cleaning

contribute to no dead zones, effective residue removal and

minimize contamination risks from wear particles. All this

contributes to fast return on investment and maximum

product yield in tanks ranging in size between 30 litres and

40.000 litres.

It is supplied with Alfa Laval Q-doc, a comprehensive

documentation package that provides full transparency of the

entire supply chain and helps make the validation process

easy.

Applications

Alfa Laval LeviMag UltraPure offers effective mixing for multiple

processes, such as those involving serums, vaccines, plasma

fractions, bacteria and cell cultures, and APIs, in the

biotechnology, pharmaceutical and other industries with

demanding sterile or high-purity applications.
