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

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
