Counterflow Cooler
Specially designed for high temperature particle cooling, uniform cooling, energy saving and environmental protection
Counterflow Cooler Introduction
The counter-current cooler adopts counter-current air cooling technology, which is suitable for cooling high-temperature pellets such as feed and fertilizer. Through the reverse contact between the cold air and the pellets, the temperature is quickly reduced, the pellet quality is improved, and the production needs of high efficiency and environmental protection are met.
Features and Advantages
Counterflow coolers have unique features and advantages and are widely used in feed, fertilizer, wood pellet and other industries.
High cooling efficiency
Adopting countercurrent cooling method, the cold air passes through the material layer from bottom to top, so that the material is gradually cooled from bottom to top, and the cooling is more uniform.
Preventing particle cracking
The traditional cooling method is prone to cause sudden cooling and cracking of the particle surface, while the countercurrent cooler cools steadily, ensures the hardness of the particles, and reduces the breakage rate.
Low energy consumption
Adopting optimized airflow design, reducing the fan power demand, effectively reducing energy consumption, low operating cost, and meeting environmental protection requirements.
Automatic control
Equipped with intelligent temperature control and discharge control system, it can monitor the cooling temperature in real time, automatically adjust the discharge speed, and ensure stable cooling effect.
Easy maintenance
The equipment is made of high-strength materials, which is sturdy and durable, easy to clean and maintain, reducing equipment downtime and improving production continuity.
Wide range of applications
Suitable for cooling feed, fertilizer, biomass pellets and other materials, and can provide customized solutions based on different material characteristics and output requirements.

Working Principle
Working Principle of Counterflow Cooler
The counterflow cooler uses a fan to send cold air from the bottom into the cooling chamber. The high-temperature particles enter from the top and come into contact with the cold air in the opposite direction. The particles are evenly dispersed in the cooling chamber, and the cold air takes away the heat, quickly reducing the particle temperature, ultimately achieving efficient cooling.
Application Scenarios
The counterflow coolers can prevent the particle surface from cracking, improve the cooling uniformity and ensure the product quality. Widely used in various cooling scenarios.
Feed processing industry
Applicable to the cooling of pellet feeds such as pig feed, poultry feed, and aquatic feed to prevent feed deformation and improve storage stability.
Biomass pellet industry
Applicable to the cooling of biomass fuels such as wood chip pellets and rice husk pellets to ensure pellet hardness, reduce pulverization, and improve combustion efficiency.
Fertilizer production industry
Applicable to the cooling of compound fertilizer and organic fertilizer pellets to reduce material temperature, improve fertilizer pellet strength, and prevent moisture absorption and agglomeration.
Food processing industry
Counterflow cooler are suitable for cooling food materials such as coffee granules and seasoning granules to improve storage safety and prevent quality degradation.
