Counterflow Cooler ---To cool biomass wood pellet
The counter-flow cooler can cool the pellets from the granulator at a temperature of 70 ° C to 90 ° C to a temperature slightly above room temperature of 3 ° C to 5 ° C, and can be reduced to safe moisture (≤ 12.5%), which is convenient for pellets. Transportation, storage and storage.
The octagonal counter flow coolers are available in different models and can be adapted to feed mills of all sizes.
At the bottom, equiped with a vibrating screener to sift out shapeless pellet.

Working Principle of counterflow pellet cooler
Counter flow cooler is mainly composed of rotating feeder, taper distributor, cooling chamber, deceleration brake engine, feed collection hopper and suction system. Biomass pellets discharged from wood pellet machines are fed into the cooler through rotating feeder and distributed evenly by taper distributor. The cold air passes through pressed pellets vertically from the bottom to the top, which is opposite to the direction of pellets entering. Cold air contacts with the cooler pellets first, and the becoming warmer air touches warm pellets, which will keep the temperature variations between the pellets and the air to a minimum degree. At last, wood pellets are sucked out by suction system and cooled down
