Why we need china counterflow cooler?

Biomass pellets or briquettes from pellet machine or briquette machine are with high moisture content above 16% and high temperature degree about 70-85℃, therefore cooler is necessary to low down material temperature to 3-5℃ higher than room temperature and for safely stored or transported in case the mildew.

 Introduction of china counterflow cooler

china counterflow cooler is necessary machine for biopellet plant. Typical applications are for cooling of feed pellets and wood pellets. It can reduce the temperature of pellets from 80~90℃to about 3~5℃ above ambient temperature. And the pellet moisture content is reduced from 17%~18% to 12%~13%. The Counter flow type pellets cooler adopts international advanced counter flow cooling technology, the cooler generates a premium effect of maintaining integrity of the pellets in the working process. With features of large capacity, smoothly functioning, high efficiency, the counter flow pellet cooler has been accepted by plenty of advanced countries.

 china counterflow cooler Working Principle
Those damp and hot particles from pellet machines are fed into cooler and scattered around evenly through feed distributor. Cold air go through wood pellets vertically and contact cold pellets; the warm air contact warm pellets but moves oppositely to the pellets dropped direction, thus makes the pellets cooled gradually. This working principle prevents cracks created by the contact of hot air and cold pellets. It is superior to traditional vertical type or horizontal type coolers.

Structure of china counterflow cooler

1>  Feeder: Ensures correctly and evenly feeding.
Outer drum: Used for gathering feed materials and hot air. Equipped with observation door and window for easily fixing.
2> Cooling room: To cool materials in a short period of time.
3> Discharging hole:  Powered by gas cylinder and electric engine.
