The counterflow cooler is a vertical design in which pellets are loaded through a top distribution mechanism and evenly spread within the unit. Under the influence of gravity, the product gradually moves downward, where it is cooled by counterflow air introduced from the bottom. This principle allows for highly efficient removal of heat and moisture from the pellet surfaces, ensuring product stability and extended shelf life.

The coolers are equipped with precise product distribution systems, adjustable valves, and discharge mechanisms, ensuring uniform cooling and minimizing the risk of overheating or uneven heat removal. Thanks to its modular construction, the unit can be adapted to different production capacities and specific requirements for the final product.

Efficient and Uniform Product Distribution

The top distributor, with the drive located outside the cooling zone, prevents product build-up and simplifies maintenance. Thanks to frequency control (VFD), precise speed adjustment ensures an even distribution of pellets across the entire cooling surface. This minimizes the formation of “dead zones” and guarantees stable product quality parameters.

Flexibility and Reliability

The design can be equipped with an intermediate deck, enabling cooling of a new batch of pellets while the previous one is still finishing in the main chamber. This significantly increases line productivity. The hydraulic drive system provides sufficient power and high accuracy of discharge control. For plants with enhanced sanitation requirements, the drive can be made of stainless steel, allowing wet cleaning without risk of equipment damage.
