3. WHERE ARE THE USERS?

4. OBJECTIVES OF FAST COOLING SYSTEMS
To comply with the laws on fresh and dairy products
Local laws
DANONE laws (final temperature under +6°C)
Increase Quality
Texture and taste
Example: for set yogurts, you have to stop the acidification in cup (cooling from 42°C to 20°C in 30 min)
Homogeneity and Shelf life of your products
A good system cools down all of the products and especially the core of the pallet.
The faster you cool down, the longer the shelf life of your product is
For natural yogurts (without additive), bacterial development is fast and has to be stopped quickly
Reduce costs
Most of users have optimized their cost by sending the cooled products directly after cooling and wrapping (the stay in a cold room for few days to finish the cooling is useless)
Optimize the ends of lines (with mechanization and automation for instance)

5. KEY FACTORS: PACKAGING AND EQUIPMENT
Packaging is not only for logistics or marketing: it is also a part of the cooling process.
For the same product, cooling time can last from 1h to more than 10h only depending on packaging. The design of packaging has to take into consideration 2 points:
Cold air has to be in contact with the products
Air must be able to circulate through the whole pallet

6. KEY FACTORS: PACKAGING AND EQUIPMENT
Good and bad examples

7. KEY FACTORS: PACKAGING AND EQUIPMENT
Good and bad examples

8. KEY FACTORS: PACKAGING AND EQUIPMENT
Objective:
to force cold air to go through
the pallet as fast as possible
Problems generally met:
by-pass all around the pallets
(example: if 40% by-pass % of cooling time)
Cold air velocity is too low problem of homogeneity and quality
Cooling systems are not adapted to the variation of size of pallets
(tall and small pallets)
Most difficult products to cool down

9. 2 SOLUTIONS
COOLING CELLS
COOLING TUNNELS

10. HIGH SPEED COOLING CELLS
For unitary loading of pallet
With individual cooling time for each pallet

11. HIGH SPEED COOLING CELLS
Performance criterion:
Avoid any by-pass
Force the air flow through the pallet
With By-pass
With air-tightness system avoiding by-pass
Standard cooling cell
FROMFROID Patented system

12. ADVANTAGES MAIN ADVANTAGES ARE: Perfect air-tightness
Allow differences in height between pallets up to 500mm
Very flexible
Stackable
Loading can be done
manually or automatically

13. POSSIBILITY OF AUTOMATIZATION

14. HIGH SPEED COOLING TUNNELS
In-line loading / unloading
For medium and large rates of production
Cooling of a flow of pallets

15. HIGH SPEED COOLING TUNNELS
Performance criterion:
Avoid any by-pass
Force the air flow through the pallet
By-passes
With air-tightness system avoiding by-pass
Standard cooling tunnel
FROMFROID Patented system

23. Example of cooling time for cups of yogurt (130g / 4,6 oz)
from 43°C to 4 +/-2 in 90 min

24. WHICH SOLUTION FOR YOU ? COOLING CELLS COOLING TUNNELS
A large range of products with different sizes and/or different filling temperatures
medium and large rates of production with quite the same cooling times between products
Manual loading/unloading
Easier for automation and mechanization of loading/unloading
Stacking on several levels when you need a compact footprint
Possibility to have different orientations of pallets depending on the packaging
Products with different cooling times
Different types of pallets: ISO1 and ISO2
Flexibility and evolutionary: you can start a production with only few cells and install additional cells regarding the evolution of production
Better homogeneity and faster cooling because air is blown on both directions
