★ The high temperature and humidity particles are cooled by counter-current cooling principle, which avoids the phenomenon of severe cooling caused by direct contact between cold air and hot materials, and thus prevents cracking on the surface of particles.
　　★ The closed air feeder is used to eliminate the phenomenon of air-crossing at the inlet and outlet. The adjustable cone-shaped bulk material mechanism can be set in the feeder, and the material distribution is uniform.
　　★ The new octagonal cooling silo has no dead angle of wind, better cooling effect, vibratory discharging mechanism, smooth discharging, adjustable speed, smooth movement, no residue, and no need to clean for variety replacement.
　　★ After cooling, the temperature of finished product is not higher than room temperature + 3 C-5 C.
