What is the Rotary Jet Mixer?

The Rotary Jet Mixer is a unique, patented, hygienic

mixer based on re-engineered Rotary Jet Heads for

the food, beverage, brewing, and other industries

What can Iso-Mix do for you?

• The Iso-Mix system based on

mixing with Rotary Jet Mixers

will effectively:

• Mix all kinds of miscible liquids

• Disperse gas into liquid

• Dissolve powders into liquid

• Clean the tank

With the Iso-Mix system you are in control

Yeast is kept in suspension from mixer

is started until mixer is turned of.

Supersaturated CO2 is nucleated by

mixer.

Improved convection gives faster

cooling.

Yeast storage

Slide 20

www.alfalaval.com

Yeast storage

• Yeast is removed (cropped) after fermentation and

kept for repitching to a subsequent fermentation.

This happens for a number of yeast generations.

• During storage it is important to mix to:

• Keep the yeast attemperated

• Remove the carbon dioxide

• To have a homogeneous solution when

repitching

www.alfalaval.com

Why Iso-Mix in yeast plants?

• Ensures homogeneous yeast slurry in yeast storage

tanks

• Prevents cavern formation

• Maintains yeast viability

• Better control of temperature profile – no hot spots

• High sanitary level

• Integrated CIP

Yeast storage

• Sedimented yeast completely

suspended within around 10

minutes of mixing

• Aeration and acid washing in

loop possible

Slide 24


Mixing in bright beer tanks

• Addition of different

liquid components

• Adjustment of e.g.

alcohol content

• Adjustment of carbon

dioxide concentration.

Mixing in olive oil

• Removing oxygen by dispersing

nitrogen

• Optimum CIP – 1 % rancid oil can ruin

99 %

• Uniform mixing

• Minimise temp. fluctuation/gradients

15-20°C

• Longer shelf life due to less

deterioration

• All in one Rotary Jet Mixer
