Product Overview
The countercurrent cooler adopts the countercurrent cooling
principle. By making the cold air flow in the opposite direction to
the high-temperature particles, efficient heat exchange can be
achieved, which can effectively reduce the particle temperature,
usually controlled between +3℃ and +5℃ of room temperature. This
design not only improves the cooling efficiency, but also prevents
the surface cracking of the particles and reduces the powdering
rate, thereby ensuring the quality and stability of the product. In
addition, the countercurrent cooler has a simple structure,
convenient operation, and is suitable for large-scale production.
Main features
Efficient cooling: The counterflow cooling box adopts the
counterflow heat exchange principle. The cooling airflow is
opposite to the material flow direction, which can effectively
reduce the temperature of the particles, usually controlled between
room temperature +3℃ and +5℃, to avoid cracking of the particle
surface and reduce the pulverization rate.
Energy-saving design: The structural design of the equipment
optimizes air flow, improves heat exchange efficiency, and reduces
energy consumption. Compared with traditional cooling equipment, it
saves about 15% energy.
Simple structure: The design of the counterflow cooling box is
relatively simple, easy to operate and maintain, and suitable for
large-scale production.
Wide range of application: It is widely used in feed processing,
fertilizer production and cooling of other granular materials,
which can meet different industrial needs.
Durable materials: Equipment is usually made of corrosion-resistant
stainless steel to extend service life and reduce maintenance
costs.
Working process
The working process of the countercurrent cooling box is as
follows:
Feeding: High-temperature particles enter the cooling box from the
top.
Air flow: The fan at the bottom sucks in cold air, and the air
flows upward from the bottom, forming a countercurrent with the
falling particles.
Heat exchange: The particles are in contact with the cold air, and
the heat is transferred to the cold air by heat conduction and
convection, and the temperature of the particles gradually
decreases.
Exhausting hot air: The air that absorbs heat is discharged through
the top of the cooling box to complete the heat exchange process.
Through these characteristics and working principles, the
countercurrent cooling box plays an important role in improving
production efficiency and product quality.

Instructions for use
When using a countercurrent cooler, follow the instructions below:
Installation location: Choose a well-ventilated place to install
the equipment, avoid high temperature and humid environment.
Operation process: Follow the operation process in the equipment
manual to ensure that each step is correct.
Regular inspection: Regularly check the various components of the
equipment to ensure its normal operation.
Precautions
When using a countercurrent cooler, pay attention to the following
matters:
Avoid overload: Ensure that the equipment operates within the rated
load range to avoid equipment damage due to overload.
Antifreeze measures: In cold seasons, take antifreeze measures to
prevent cooling water from freezing and damaging the equipment.
Safe operation: Operators need to be trained to understand the safe
operating procedures of the equipment to ensure safe production.
Through the above introductions, it can be seen that the importance
and efficiency of countercurrent coolers in industrial production,
and reasonable maintenance and use can significantly improve
production efficiency and product quality.
