The counterflow cooler is a device for cooling mixed feed and pellet particles. This equipment is most often used for cooling feed and wood pellets, as well as cellulose pellets and similar products.

The raw material is fed continuously into the main chamber through an inlet valve, where it forms a uniform layer at a set height. The rarefaction causes a cold air flow through the pellet layer, which draws excess heat from the product.

As it cools, the bottom layer of product is transferred to the discharge chamber using an electric moving grate, which ensures smooth discharge.

The technical features of the LesInTech cooling unit are as follows:
  1. The cooling chamber is made of mainly structural and stainless steel.
  2. The pellet temperature at the inlet is max. +90°C and at the outlet +10°C of the cooling air temperature.
