Advantages of using cold pasteurization
Technology
Product portfolio
Use cases
Microbiology
Reducing complexity in the dairy
1. Lowers the energy consumption by more than 90%
2. Inactivates bacteria, fungi, spores and viruses
3. 7-14 seconds processing time
4. Product quality – reduced thermal history
5. Reduced CIP requirements – 60% less water
6. Reduction in process complexity
7. Enables the transition to sustainable energy
The main advantages of UV
Technology
• 90% lower energy use• 60% lower water use• 99,9999% reduction in
bacteria
Product portfolio
• Fully scalable
• 90% lower energy use
• 60% lower water use
The CPS
- Shelf life extension of liquid milk after HTST
Use cases
Replacement of thermalizer steps e.g. sweet
and acid whey and whey concentrate Shelf life extension of liquid milk after HTST
Cheese milk bacteria & spore
inactivation
Use cases
Quality assurance & potential for increased
uptime for RO & UF e.g. skim milk permeate
Bactofuge replacement for spore &
bacteria reduced milk
Microfiltration replacement
For bacteria reduced skim milk
Use cases
Sweet butter milk
Lactoferrin & colostrumBrine single pass or recirculation
And many other applications..
Waste water, raw milk weigh in, milk
concentrates etc.
