How does tank mixers work?

Tank mixers such as magnetic mixers and rotary jet mixers have different operating principles.

Rotary jet mixer nozzles feed the liquid, gas, or powder into the base liquid in the tank.

These jet mixers rotate around both horizontal and vertical axes in a 360° movement.

This three-dimensional rotation enables fast, efficient tank mixing of the injected liquid,

gas, or powder without requiring batch rotation. A circulation loop enables liquid to be

pumped from the bottom of the tank and back into the industrial tank mixers.

For faster mixing requirements, several rotary jet mixers can be installed in series as part

of a larger process mixer system.

A magnetic mixer (also called a magnet mixer) has a radial impeller installed inside the tank.

Due to the torque from a magnetic coupling, the impeller rotates, mixing the fluid inside

the tank. The patented design of the levitating impeller enables dry running, maximizing

yield by mixing down to the last drop. It also ensures full drainability of the process fluids

and the free flow of Cleaning-in-Place media and steam throughout the mixer, ensuring

thorough cleaning.

Maximize uptime and yield with Alfa Laval tank mixers for hygienic and aseptic applications.

Patented technology ensures efficient and uniform mixing of powders, liquids and gases

while reducing the total cost of ownership. Compact, energy efficient and easy to maintain,

these tank mixers enhance process flexibility, making quick, easy work of blending various

product formulations with diverse viscosities, densities and volumes.

Working principle

Power from the motor – direct or via gearbox – drives the shaft,

rotating impellers for optimal mixing and low energy

consumption. The unique EnSaFoil™ two or three blade impellers

generate strong axial flow with minimal shear, ensuring uniform

mixing and blending. The high mixing efficiency cuts energy

consumption by up to 80% and limits heat transfer to the product,

lowering cooling requirements.

Options

•Pharma (UltraPure), Food or Industrial versions

•Welding flange (mandatory accessory) – also versions for upgrade of

existing agitators

•Stainless steel shroud for gear motor

•Various surface treatments for gear motor according to DIN EN ISO 12944-2

•Various elastomer materials or shaft seal face combinations

•Special alloy on request

•Various documentation packages

•Condition monitor (accessory)

•Service tools for maintenance (available as a complete service suitcase

including all tools necessary for doing service)

•Spare Part kits including complete cartridge spare unit for reduced downtime

Standard design

EnSaLine S consists of a drive unit with bearing frame, shaft with

special cartridge shaft seal, and EnSaFoil™ impellers with two or

three blades. Inside the tank, the fully flushable design with no

mounting flange and the hygienic seal housing offer excellent

cleanability. EnSaLine S agitators give rapid and tool-free access,

enabling one technician to complete service in under 30 minutes.

During maintenance, the shaft remains securely fixed and there is

no need for the technician to enter the tank. Sealings and O-rings

can be replaced from the outside. EnSaLine S is prepared for

wireless condition monitoring.

Standard design

The ALTB top-mounted agitator consists of a drive unit with

shaft, shaft seal, bottom steady bearing (shaft support inside

the tank), and specially designed energy-saving (EnSaFoil)

impellers with two or three blades. The bottom steady bearing

extends agitator service life and reduces cost. The Alfa Laval

agitator range includes top-, bottom- and side-mounting

models.

Working principle

The Alfa Laval ALTB top-mounted agitator has an electrical

drive motor that transmits the energy required for mixing and

blending, either directly or via a gearbox, to the agitator shaft.

The shaft rotates, supported by the shaft support, turning the

EnSaFoil impellers. The impeller movement creates a high flow

with low shear due to the highly effective axial pumping effect

on the liquid in the tank. This results in effective mixing and

blending of the entire contents of the tank.
