|Why Need Pellet 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.
Counter Flow Pellet Cooler Introduction
Counter flow wood pellet cooler is a necessity in cooling large capacity biomass pellets and wood briquettes to produce high quality biomass fuels. Works in counter flow cooling principle, it can avoid pellets or briquettes cracking or breaking and cool particles rationally. Economic space occupation and easy operation, counter flow cooler is the ideal cooling equipment for particle materials nowadays in China.
|Counterflow Pellet Cooler Structure
☆ 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.
☆ Cooling room. To cool materials in a short period of time.
☆ Discharging hole. Powered by gas cylinder and electric engine.
|Wood Pellet 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.
Pellet Cooling Machine Features
1. Large cooling room and cooling capacity from 5-30t/h.
2. Countercurrent cooling principle, reasonable design and good cooling effect.
3. Cold air enters from the bottom ensures high cold air efficiency.
4. Unique rotating structure to distribute pellets evenly and cool them completely.
5. Suitable to cool bulk, platy or particles materials, especially to puffing materials and other large volume material.
