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.

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.
