Zhengzhou Fanda Machinery Co., Ltd. is one of the leading manufacturers and suppliers of pellet cooling machine in China. With abundant experience, we warmly welcome you to buy cheap pellet cooling machine for sale here from our factory. For price consultation, contact us.
Wood pellets discharged from the pellet mill at a temperature is 70℃－90℃, if do not cool down there will be a crack on the surface of the pellets, so cooling pellets is an essential process in wood pellet plants.
Our counter-flow pellet cooler can cool the pellets from 70℃－90℃ to room temperature in a short time, and reduce the safety moisture by ≤10％, this makes the pellet convenient for transport, storage, packing, and keeping.
Counterflow pellet cooler is a new type of popular cooler on the international market. It uses the counter-flow cooling principle to cool the pellets with high temperature and high moisture.
Pellets feed on the airlock on top of the pellet cooler and fall inside the cooling tank, the cold air comes into the cooling tank from the bottom of the pellet cooler by the suction of the air fan, and inside the cooling tank hot pellets meet the cold air, when cold air mix with hot pellets, the temperature of pellets reducer, and finally, pellets discharged from the discharge door and go to discharge chute while hot air and dust go to air fan by suction of air fan. The hot air is finally emission from the discharge pipe of the air fan and dust goes to the dust tank at the bottom of the cyclone.
On the pellet cooler, there is a sensor to indicate the level of pellets inside the cooling tank, inside the electric panel there is a time delay, the sensor and time relay work together to control the cooling time and discharge time, when pellet level inside the cooling tank reaches the upper level and cooling time reached, the time relay gives a signal to the electric panel, the panel control motor or air cylinder running to open the discharge door, pellets start to go to discharge chute from cooling tank until the level of the pellets inside the cooling tank reaches the lower level the sensor give panel signal to start the motor or air cylinder to close the discharge door and stop discharge pellets.
The whole process is automatically working, the sensors, time relay, and electric panel control the process. But if you want to control the cooling process manually, the electric panel can use manual control.
Usually, we equip a vibration sieve under the pellet cooler or a rotary sieve after the pellet cooler to sieve the pellets thus picking out the small-size pellets.
Advantage of counter-flow pellet cooling machine
Have a feeder airlock on top, to avoid air emission from the top.
Under the feeder airlock, there is a rhomb feeder, this feeder can separate the pellets evenly inside the cooling tank and prevent pellets broken during they are falling down.
Equipped with air fan, cyclone, and dust tank to collect dust and suction air.
Automatically working.
Short cooling time, can cool down pellets from 70℃－90℃ to +3～5℃ of room temperature within 6-10 minutes.
Octangle cooling tank, the temperature and pellets feeding inside the cooling tank are even, to make sure all the pellets after cooling are the same temperature and improve cooling efficiency.
