Counterflow Cooler
Efficient cooling equipment for granular materials

Counterflow Cooler Overview
Counterflow coolers are highly efficient cooling devices that are typically used to cool hot materials in industrial production processes. It works on the principle that the cooling medium (e.g. air or water) flows in the opposite direction to the hot material, thus increasing the heat exchange efficiency.

Features and Advantages of Counterflow Cooler
Features and Advantages
Efficient heat exchange
Countercurrent cooler cooling medium and high-temperature materials flow in the reverse direction, the temperature difference is large, heat transfer accelerated, heat exchange efficiency is significantly improved.
Energy saving
Based on high-efficiency counter-current design, the cooling more fully utilise the heat absorption of the medium, the same effect of the media flow less, can effectively save energy, reduce costs and improve efficiency.

Structural Components of Counterflow Cooler
Structural Components
Cooling air system
The cooling medium is fed into the interior of the machine by means of fans, pumps, etc.
Feed system
Used to feed hot material into the interior of the machine, usually via a conveyor belt or hopper.
Cooler housing
Protects the internal components and is usually made of high temperature and corrosion resistant materials.
Heat exchange area
The area where the material comes into contact with the cooling medium, usually designed as a flow channel.
Discharge system
Used to discharge the cooled material so that the material goes to the next process.

Working Principle of Counterflow Cooler
Working Principle
The working principle of Counterflow Cooler is to achieve efficient cooling by using the counterflow principle. Hot materials enter from the top and slowly move downward under the action of gravity. The cooling medium (such as cold air) flows upward from the bottom and forms a relative motion with the hot materials. In this process, the hot materials are fully in contact with the cooling medium, heat is exchanged, the hot materials are cooled, and the cooling medium absorbs the heat and is discharged from the top.
Counterflow Cooler Application Scenarios
Application Scenarios
Organic Fertiliser Processing
Counterflow cooler for high temperature processing of organic fertiliser, it can quickly cool, avoid the loss of fertilizer nutrients, maintain a good state of particles, easy to store, transport and use.
Biomass Pellet Processing
In biomass pellet processing, a counter-current cooler is used to handle hot biomass pellets, which effectively cools down the temperature and ensures the firmness and stability of the pellets.
Feed processing
In the field of feed processing, the counter-current cooler cools the hot feed after pelleting and ensures that the feed pellets are dry and of the right hardness for storage and transport.
Food Processing
In food processing, counterflow coolers are used for baking, frying and other hot materials for rapid cooling, maintaining food flavour and enabling mass production.
Chemical Industry
In the chemical industry, counter-current coolers are used to cool hot materials after chemical reaction, block liquid or granular materials, make the material properties stable, so that the chemical process can be carried out smoothly.
Metallurgical industry
In the metallurgical industry, this cooling machine is used to cool metal and ore materials, such as sintered ore and steel. It effectively reduces the temperature, saves energy and maintains the material properties.
Counterflow Cooler Buying Guide
Buying Guide
Define production requirements
You need to consider the hourly production rate, the initial temperature of the material and the target cooling temperature range to ensure that the equipment is suitable for the requirements of the production line.
Cooling Efficiency and Uniformity
Countercurrent cooling machine should be able to effectively cool the material to a state close to the ambient temperature, while ensuring the uniformity of cooling to avoid the phenomenon of insufficient local cooling.
Equipment material and durability
Countercurrent coolers are required to handle high temperature or high humidity materials, so equipment made of stainless steel or high-strength, corrosion-resistant alloys is preferred.
Environmental performance
Choosing a counterflow cooler with low energy consumption and high heat exchange efficiency can reduce production costs. Pay attention to the dust control ability of the equipment.
Automation function
The cooler should be equipped with features such as temperature monitoring and material level control, which can effectively reduce the complexity of manual operation and improve production efficiency.
After-sales support
Choose an experienced and reputable brand that has excellent after-sales service, including fast-response technical support, spare parts supply and equipment maintenance guidance.
Frequently Asked Questions.
Counterflow cooler through the cold air from the bottom up and hot materials from the top down reverse contact, the heat of the material away, so that the material will be cooled to close to room temperature, while reducing the moisture, enhance the stability of the material storage.
This cooling machine is widely used for cooling materials such as feed pellets, wood pellets, fertiliser pellets and so on. As long as the granular materials are granulated or processed at high temperature, the counterflow cooler is usually capable of doing the job.
Qualified cooling effect usually requires the material to be cooled to ambient temperature +3~5°C and the moisture content to be reduced to a safe range (usually ≤12%) to prevent caking or mould during storage.
Usually it needs to be used in conjunction with granulator, elevator, sifter and conveying equipment to form a complete production line to ensure smooth material transfer and overall production efficiency.
When installing the equipment, you need to consider the height and footprint of the equipment, and at the same time ensure that there is enough space around for maintenance and operation. In addition, there should be reliable ventilation conditions to ensure that the cooling air flow.
