SKLN Counterflow Cooler

  • Capacity: 5-15 t/h
  • Feed Pellet Size: custom
  • Feed Pellet Forming Rate: custom
  • Application: The counterflow cooler can cool the pellets to a temperature slightly higher than the room temperature

The counterflow cooler efficiently lowers pellet temperatures from 70 ℃ to 90 ℃ to just above room temperature, approximately 3 ℃ to 5 ℃. It also reduces moisture to a safe level (≤12.5%), enhancing convenience for pellet transportation and storage.

SKLN Counterflow Cooler Introduction

The pellet cooling process is a crucial step in the granulation phase. Our SKLN series counterflow cooler is specifically designed to efficiently cool pellets characterized by high temperatures and moisture levels. This innovative cooler employs a counterflow mechanism where hot air comes into contact with hot pellets, and cool air interacts with already-cooled pellets. This method prevents surface cracks on the pellets that may result from abrupt cooling caused by direct contact between cool air and hot pellets.

With the SKLN counterflow cooler, pellets with temperatures ranging from 70 ℃ to 90 ℃ can be cooled to just slightly above room temperature, approximately 3 ℃ to 5 ℃. Additionally, the cooler effectively reduces the pellet moisture to a safe level (≤12.5%), facilitating convenient transportation and storage. The machine features a unique sliding valve mechanism for material discharge, ensuring smooth operation and efficient material discharge.

SKLN Counterflow Cooler Advantages

Uniform cooling

It is widely used in the feed and biomass processing industry to cool various granular materials.

Small footprint

The vertical overall layout, compact structure, and small footprint.

Easy to maintain

There is an inspection door on the front of the equipment, observation windows on the side, and a top cover, which are convenient for observation and inspection.


The discharge pressure relief plate increases the working load, reduces deformation, and prolongs the life of parts.

Stable operation

The geared motor drives the eccentric shaft for transmission, which is stable and reliable, with low noise and easy installation and maintenance.

Unique design

The octagonal cooling bin prevents dead ends.
