what is pellet cooler machine?

The feed pellet cooler machine is widely used to match with the pelletizing process of feed pellet plant, which aiming at further ripening of the materials and improve the feed pellets quality and water-resistance. With the characteristics of high automation degree and advanced technology, it is ideal equipment for industrial production of special aquatic feed and high grade feeding for domestic animals.

The pellet cooling machine has 2 functions: cool down the pellet temperature and reduce the pellet moisture. The pellet coming out from pellet machine is at temperature 70℃～90℃, and through the pellet cooler machine, the temperature will be less than 3℃～5℃ above room temperature. Besides, the feed pellet cooler machine make pellet moisture less than 12.5%, which is good for the pellet storage and shipment.

Advanced Feed Cooling Technology: Counterflow Mechanism

The pellet cooling machine takes advantage of counter current cooling principle to cool the pellet material with high temperature high humidity. Cold air moves vertically through the material, first chilling, then heating as it contacts hotter material, opposite to the material flow. The particles gradually cooled and moved in a straight line. This can avoid the shock cooling phenomenon when the cold air contacts with the hot material, thus can prevent the pellet appearance surface cracking.

Smart Control & Components

• Inlet Rotary Valve: The hot granules from the feed pellet machine enter the unit bin through the inlet rotary valve.
• Distributor: Below the inlet rotary valve, the distributor evenly distributes the particles in the cooler.
• Liquid Level Sensor: A liquid level sensor controls the particle layer height. Level sensors ensure that the product layer remains at a predetermined height.
• Pendulum Discharger: When particles activate the level sensor, the pendulum discharger operates and discharges the particles through the hopper.
• Overflow Sensor: To prevent overflow, the cooler has an overflow sensor that halts product supply to the feed cooling system.

6 Engineering Advantages of SKLN Cooling Systems

1. Octagon Design: Cooling tank adopts octagon design, which can ensure the cooling has no dead angles.
2. Stable Discharging: The material discharging device adopts slide valve, ensuring stable, reliable operation with minimal material residue.
3. High Cold Air Utilization: Cold air fully enters from the bottom, using a large intake area and high cold air utilization.
4. Crack Prevention: Avoid particle surface cracking by preventing direct cold air and hot particle contact.
5. Quality Preservation: High cooling speed and favorable cooling effect. The feed pellets cooler can cool more pellets while maintaining optimum pellet quality.
6. Easy Operation: High automation degree and advanced technology, lower power consumption, easy operation and cleaning.

Countercurrent Pellet Cooler Machine Technical Parameters

Additional Operating Specifications

☀Cooling Time:    ≥ 6-10 min
☀Pellets Temperature after Cooling:    ≤  ambient temperature + 3~5℃
☀Aspirating Capacity: Dependent on specific model volume

Critical Quality Control: Moisture & Airflow Management

1. Crack Prevention: Cooling can directly affect the quality of final feed pellets, so it should be a gradual process. Quick chilling of pellets can cause outer layer cracks, leading to higher abrasion.
2. Pellet Size Factors: It should be noticed that small pellets emit heat and moisture more quickly than large pellets. Even distribution of pellets in the pellet cooler machine also enhances the cooling process.
3. Optimized Air Speed: Generally speaking, air speed in counter flow pellet cooling machine should stay between 0.8 and 1.5 m/s.
