Counterflow Pellet Cooler

The counterflow pellet cooling machine is the most advanced pellet cooling technology in the world. It is a new generation of cooling equipment researched and developed, which is mainly used to cool high-temperature pellets after pelletizing.

The temperature of the cooled material is not higher than the outside temperature +5°C, and the precipitation rate is not less than 3.8%, which plays a good role in producing high-quality pellets and extending the storage time of pellets.

RICHI Pellet Cooling Machine

During the entire working process of the pellet cooling machine, the fan is always on, because the pellets flow from top to bottom, and the wind is opposite to the flow direction of the pellets, which flows from bottom to top, and the cold wind and the cold the pellets are in contact, and the hot air is in contact with the hot pellets, so this type of pellet cooling machine is called a counter-flow pellet cooler.

Due to the high temperature and moisture of the pellets in the silo, the pellets stay in the silo body for a period of time. Natural air enters from the bottom through the suction of the fan and passes through the material layer in the silo body for heat exchange. At the same time, the heat and moisture of the pellets are taken away by the fan to cool the pellets and reduce the moisture.

The counterflow pellet cooler has a good cooling effect and a high degree of automation;
Low noise, simple operation, and low maintenance;
The model widely used at home and abroad is an advanced replacement pellet cooling machine.

RICHI will configure suitable pellet cooling equipment according to the different needs of customers and the size of the output.

What is a pellet cooler?

The counterflow pellet cooler is the most advanced pellet cooling technology in the world. It is a new generation of pellet cooling equipment researched and developed, which is mainly used to cool high-temperature pellets after granulation. The pellet cooler has a unique cooling mechanism. The cooling air and the high-temperature and high-humidity material move in the opposite direction so that the material is gradually cooled from top to bottom, avoiding the surface cracking of the material caused by the general vertical cooler due to the sudden cooling, and the core moisture and heat It is difficult to distribute and other shortcomings, and the cooling effect is better than the existing similar products in China. The temperature of the cooled material is not higher than the outside temperature +5℃, and the precipitation rate is not less than 3.8%. It plays a good role in producing high-quality pellets, extending the storage time of pellets, and improving economic benefits. The counterflow pellet cooler has a good cooling effect, high degree of automation, low noise, simple operation, and low maintenance. It is a model widely used abroad and is an advanced replacement pellet cooling equipment.

How does a pellet cooler work?

The hot and wet pellet material compressed by the pellet mill enters the inlet of the closed air feeder at the top of the pellet cooling machine, and after the pellet material is divided through the closed air feeder and the rhombohedral diffuser, The pellet material flows into the silo body from the front, back, left, right, and the middle five ways of the top part of the silo. In the beginning, the pellet material gradually accumulates, and when the material is filled with the silo, when the material touches the loading level device, the motor is turned on and starts to work. The motor drives the discharge frame to reciprocate left and right through the reducer and eccentric mechanism. In the process of reciprocating discharge, when the relative position between the movable discharge frame and the fixed frame reaches a certain level, the material will fall from the silo body and be discharged into the gap between the movable discharge frame and the fixed frame. The hopper does not discharge when the relative positions of the movable discharge frame and the fixed frame are staggered. The material is discharged out of the pellet cooling machine intermittently during this reciprocating movement. When the discharge is larger than the feed, the pellet material in the pellet cooling machine drops to the lower material level. The motor stops rotating, and the discharging stops accordingly. When the material touches the loading leveler, it will start working again. During the entire working process of the pellet cooler, the fan is always on, because the material flows from top to bottom, and the wind is opposite to the flow direction of the material, flows from bottom to top, and the cold air and the cold material flow in the opposite direction, contact, hot air and hot material contact, so this type of pellet cooler is called a counter-flow pellet cooler. Due to the high temperature and water content of the pellets in the silo, the material stays in the silo for a period of time. Through the suction of the fan, natural air enters from the bottom and passes through the material layer in the silo for heat exchange. At the same time, the heat and moisture of the materials are taken away by the fan to cool the materials and reduce the moisture.

Why use a pellet cooler in a wood pellet production line?

The function of the pellet cooler in the wood pellet production line is to cool off the warm as well as fresh generated pellets to room temperature level. This is essential for a number of reasons. To start with, the cooling process assists to strengthen the pellets, making them stronger and also less most likely to damage during storage or transportation. Second of all, cooling down reduces the moisture material of the pellets, which can reduce the danger of mold and perishing during storage. Lastly, cooling the pellets aids to decrease the friction between them, which can lead to smoother and much more effective handling in the production line.
