Alfa Laval Rotary Jet Mixer

Alfa Laval’s Rotary Jet Mixer is designed to be used in the brewery and beverage, dairy, personal care and biopharm industries. Alfa Laval’s rotary jet mixers effectively handle liquid mixing, gas dispersion, powder mixing and tank cleaning while reducing mixing time, energy consumption and costs.

Alfa Laval’s Rotary Jet Mixers are a patented technology by Alfa Laval, proven through the proven rotary jet head technology, providing 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.

Unmatched mixing performance 

In many applications, the Rotary Jet Mixer provides the fastest and most efficient mixing results. It also handles gas dispersion (aeriation, deaeriation, carbonation), powder mixing and cleaning-in-place (CIP). Its patented rotary jet mixing technology is based on rotary jet head technology, which has been modified to handle mixing of liquids, gas and powder. Rotary jet mixers can be used in tanks between 100 and 800,000 liters in size.

To meet your mixing needs there are also agitators and magnetic coupled mixer by Alfa Laval offered for a more refined solution.

Faster, effective mixing 

When using the Rotary Jet Mixer the capacity can be increased, resulting in greater productivity, higher product quality, and improved utilization of process plant resources.

Handles multiple applications 

The Rotary Jet Mixer helps reduce capital expenditures and operating expenses while achieving fast and efficient mixing.  A single Rotary Jet Mixer can handle liquid mixing. gas dispersion and powder dispersion applications – plus tank cleaning – without requiring separate equipment for each process and thereby delivering significant savings.

Effective simple design 

The system offers savings in tank and  supporting structure because the motor and pump can be placed on the floor. And at the same time the Rotary Jet Mixer being placed under the liquid surface is a hydraulically balanced system which does not create any significant loads on the tanks. In addition to this easy-to-install design facilitates retrofitting of existing tanks.

Making a good thing even better

A number of pre-engineered Skid Mounted Pump Units are available to complement the Rotary Jet Mixers. In addition to a Rotary Jet Mixer end-users also require a pump and instrumentation for their mixing system. To make it easy for them a number of pre-engineered unit with all the necessary equipment have been design. For end-users this will save time and resources as they can bypass engineering and procurement. All they have to do is connect two pipes, do the electrical wiring, set up the variable frequency drive – and they are ready to go.

Operating Principal 

Alfa Laval’s Rotary Jet Mixers are positioned under the liquid surface. Liquid is fed through the nozzles of the Rotary Jet Mixer. To achieve optimal circulation within the tank, the system uses a closed circulation loop. Two or four nozzles rotate around both the horizontal and vertical axes. The double rotation enables the jets to reach the entire tank volume, providing fast, efficient mixing of the injected liquid, gas or powder. For faster mixing requirements, several Rotary Jet Mixers can be installed in series.

Tank cleaning included

Alfa Laval’s Rotary Jet Mixer does double duty. After completion of the mixing process, the mixer’s jet nozzles can be used for spraying cleaning liquids in the tank to effectively clean tank surfaces.

Skid mounted unit 

Three different pre-engineered Skid Mounted Pump Units are available to supplement the portfolio of the Rotary Jet Mixers. The three unit available comes with 7.5 kW, 11kW or 15 kW pumps. The unit is mounted on a stainless steel frame and consists of the following Alfa Laval components; an energy-efficient LKH centrifugal pump, a variable frequency drive, piping, two pressure gauges, manual LKB-2 butterfly valves at the inlet and at the outlet and LKB-2 drain valve.

Applications Examples: 

Beer fermentation

Alfa Laval’s Rotary Jet Mixer is used for mixing in beer fermenters. Applying forced mixing in beer fermenters reduces processing times by up to 30%. As a result  fermentation capacity is maximized and reduction in operational costs is achieved.

Mixing beverages 

Applying Alfa Laval’s Rotary Jet Mixers optimized production processes in the beverage industry. The mixers are used for different beverage applications such as mixing beverages containing fruit pulp, dissolving flavors, aspartame and other powders and for tank cleaning – Cleaning-In-Place (CIP). A single mixer can be used for several different operations in the same tank for instance for liquid mixing, deaeration, carbonation and dissolving of powders.

Deaeration 

Alfa Laval’s Rotary Jet Mixer can be used for effective deaeration. Minimizing the oxygen content in liquid food products like soft drinks, beer and edible oil leads to extended shelf life and improved taste stability.

Product range

The Rotary Jet Mixers are available in four different models (IM10, IM15 IM25). They are designed for tank volumes between 100 and 800,000 liters in size and capable of handling re-circulation flow rates up to 90 m³/hour.

Applications 

The IM Rotary Jet Mixer is designed for liquid mixing, gas dispersion (aeration, deaeration, carbonation) and powder mixing in process and storage vessels from 1 to 1000m³ (across the diverse range of models available; IM10, IM15, IM20, IM25)  in size across the dairy, food, beverage, brewery, healthcare, home and personal care, and biotechnology industries.

When the tank is empty the rotary jet mixers also act as a superb Cleaning-In-Place (CIP) system, saving water, cleaning media and energy compared to using a spray ball CIP system.
