Counterflow Pellet Cooler
The pellet cooler reduces the temperature and moisture of the product leaving the pellet mill. In the counterflow model, ambient air moves from the bottom upward and contacts the hot product. By cooling gradually, it preserves product strength and provides suitable conditions for conveying and packing.

Frequently Asked Questions
Why is cooling pellets after production necessary?
The product leaving the pellet mill is hot, and proper cooling prevents sweating, moisture increase and quality damage during storage.
What is the advantage of a counterflow cooler?
This design gives gradual, more even heat transfer and reduces the chance of thermal shock and product breakage.
What should the product temperature be after leaving the cooler?
The product should usually be close to ambient temperature; the exact value depends on environmental conditions, humidity and product type.
