Alfa Laval RJ Mixer IM-10 Tank mixers

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.

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.

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.
