1. The counter flow cooling principle is adopted to cool the pellets with high temperature and moisture. Hot air touches hot pellets and cool air touches cool pellets so as to avoid the pellet surface crack caused by sudden cooling produced by direct touching between cool air and hot pellets. At the same time, the airlock is used for feeding and space of air inlet bigger, therefore it can get better cooling effects;
2.Slide reciprocating discharger has smooth and reliable discharging, low residue;
3.It is suitable for pellet cooling;
4.Pellet temperature after cooling is less than three to five ambient temperature;
5. Low power consumption, easily operation.
