What happens after pelleting in feed pellet production is just as important as pelleting itself. Modern coolers have always been counterflow, which makes sense in feed mills. This is why this cooling process is so effective for the quality of the final product.
Cooling Challenges in Feed Pellet Production
Feed pellets produced directly come out of the pellet mill at a temperature of 70-90°C, with a relative moisture content of 15-17%. Lack of sufficient cooling:
Pellets are soft and prone to breakage
Excessive moisture can lead to mold growth
Loss of nutrient stability
Significantly reduced pellet shelf life
3 Reasons Counterflow Cooling Works Best
Gentle Yet Effective Temperature Control
Gradually reduces pellet temperature
Prevents thermal shock that causes cracks
Maintains pellet structure integrity
Superior Moisture Management
Removes 3-5% excess moisture
Achieves ideal 10-12% final moisture
Prevents clumping during storage
Unmatched Consistency
Every pellet receives equal cooling
No "hot spots" in the cooling column
Uniform quality throughout batches
How does it work? (In simple terms)
As can be seen, hot particles are added at the top and cold air is added at the bottom:
Particles flow downward
Air flows upward
They found a compromise solution
Related to this is the transfer of heat and moisture
The particles are cooled and dried before coming out at the bottom
This is countercurrent activity, which ensures maximum cooling efficiency.
