Energy Saving Counter-Flow Feed Pellet Cooler for Biomass Pellets and Feed Pellets

Pellet cooler is mainly used for cooling of pellet in the pelleting section. It cools the pellet coming from pellet mill and with a temperature of 70°C-90°Cto a temperature 3°C~5°C slightly higher than ambient temperature, and is capable of lowering to a safety moisture content. The cooled pellets not only improve the pellet firmness but also can prevent from going mouldy, that it is good for the transportation and storage of pellet feed.

1) The counter flow pellet cooler 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) Low pow consumption, easily operation.
4) Pellet temperature after cooling is less than 3-5ºC ambient temperature.

Features of counter-flow pellet cooler:

(1) This machine adopts the counter flow cooling principle to cool down pellets with high temperature and high moisture content. This cooling method can avoid the sudden cooling because of the direct contact between the cold air and materials . which will prevent the surface cracking of the pellets.
(2) The latest design of octagonal cooling chamber had no dead angle.
(3) Feeding via airlock had large wind area and remarkable cooling effect .
(4) The reciprocating slide valve discharging mechanism is stable and reliable in working and guarantee less residue.
(5) Low energy consumption and easy operation .
(6) The temperature of cooled products is not 3ºC-5ºC higher than room temperature, which is suitable for cooling granule materials
(7) We also provide cooler with panel turnover discharging system for your choice. The hydraulic
driven discharging mechanism is usually used for cooling the extruded or expanded materials .
