Counterflow Cooler

Efficient cooling equipment for granular materials

Counterflow cooler

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.

Highly adaptable

The cooling machine has excellent adaptability to a wide range of forms and properties of materials, both solid and liquid, and plays an important role in multiple industries, providing universal cooling solutions.

Uniform Cooling

Countercurrent cooler structure and airflow design is unique, can ensure that the temperature of each part of the material is uniform, to avoid quality differences, important for strict temperature control process.

Space saving

The compact design and small footprint of this cooling machine compared to other cooling equipment allows for flexible placement in limited spaces to meet demand and improve space utilisation.

Low Maintenance

The simple design and construction of the cooling machine, with its uncomplicated components and drives, makes routine maintenance easy and convenient, reducing costs and downtime.

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.
