Counterflow Pellet Cooler

The counterflow pellet cooler is applied for efficient cooling of hot and moist pelleted products with good flowing capabilities.Typical applications are for cooling of feed pellets and wood pellets,it can reduce the temperature of pellets from 80-90 Celsius Degree to about 3-5 Celsius Degree above ambient temperature.And the pellet moisture content is reduced from 17%-18% to 12%-13%.The advantages in energy efficiency,easy operation,great cooling result and lower investment cost have made the counterflow pellets cooler the preferred choice for most users of feed and wood pellet plant

Counterflow Pellet Cooler Features and Benefits

1.The pellet cooler takes advantage of counter current cooling principle to cool the pellet material with high temperature high humidity,it can avoid the shock cooling phenomenon when the cold air contacts with the hot material,thus can prevent the pellet appearance generating crazing.
2.Cooling tank adopts octagon design,which can ensure the cooling has no dead angles.
3.Adopt air-closed material feeder,large inlet area,outstanding cooling effect.
4.The material discharging device adopts slide valve reciprocating type,stable and reliable running,little residual.
5.The cooled feed pellets temperature won’t be higher than ambient temperature 3-5 Degree Celsius,also suitable for cooling particle material.
6.High cooling speed and favorable cooling effect.the counterflow pellets cooler can cool more pellets while maintaining optimum pellet quality.
7.Lower power consumption,easy operation and cleaning,high production efficiency.

Counterflow Pellet Cooler Application

The counterflow pellet coolers are mainly used in large or medium size feed pelletizing plant and wood pellet production line.The pellet coolers can cool the pellet material and reduce the material temperature and moisture content.So the animal feed pellets are more convenient to package,transport and store.

What Should be Noticed When Operate the Counterflow Pellet Cooler

1.Start the air-lock device and draught fan before the cooler starting to work
2.Adjust the level indicator position according to the yield requirement.When the yield is high,install the level indicator at top position,on the contrary,install it below.
3.When the cooler stops working,expel the material in the cooler through operating the hand switch.
4.Don’t open the observation door when the cooler runs.

How to Maintain Counterflow Pellet Cooler

1.Check the fastenings periodically to see if they are loose and falling off or not
2.Clean the cooling zone plates on time,ensure the air current is unobstructed.
3.Add lubricating oil to the bearings and electric motor at fixed periods

How to Choose a Pellet Cooler For Pellet Plant

The counterflow pellet cooler material discharging device adopts slide valve reciprocating type.it is suitable for pellet materials.Some coolers are with shutter type discharge mechanisms,which are adopting hydraulically powered discharging mechanism.There coolers are suitable for puffed and expanded materials.
