XUANYU Belt Cooling Machine: High-Efficiency Continuous Industrial Belt Cooling Solution

XUANYU Belt Cooling Machine is a high-performance continuous industrial cooling equipment, mainly composed of a conveying mesh belt, cooling chamber, ventilation system, refrigeration system (optional), and intelligent control system. It is designed to continuously reduce the temperature of high-temperature materials (in powder, granular, block, sheet, or strip form) by conveying them through the cooling chamber via a corrosion-resistant mesh belt, ensuring the cooled materials meet specified temperature requirements for further processing, packaging, storage, or transportation. Integrated with advanced convection heat exchange technology and uniform airflow distribution design, it features stable operation, high cooling efficiency, energy conservation, uniform cooling effect, and strong adaptability to different high-temperature materials, widely serving multiple industrial fields. It has obtained multiple authoritative certifications to guarantee product quality, operational safety, and compliance with global environmental and quality standards.

Core Technology & Working Principle

XUANYU Belt Cooling Machine adopts advanced continuous convection heat exchange technology, combined with optimized airflow distribution and multi-layer belt conveying design, to achieve rapid, uniform, and continuous cooling of high-temperature materials through efficient heat transfer between materials and cooling air. The specific working process is as follows:

1. Material Feeding: High-temperature materials (with inlet temperature up to 600°C, adjustable according to model) are evenly fed into the inlet of the cooling chamber through a dedicated high-temperature resistant feeding device (such as a high-temperature screw feeder or vibrating feeder) onto the top layer of the conveying mesh belt, ensuring continuous and stable material supply with uniform thickness.
2. Continuous Conveying: The mesh belt (made of high-temperature resistant, corrosion-resistant, and wear-resistant stainless steel 304/316L or special alloy mesh) runs at a stepless adjustable speed, conveying high-temperature materials continuously through the cooling chamber. For materials requiring longer cooling time, multi-layer mesh belts are adopted to extend the cooling path, improve space utilization, and ensure sufficient heat exchange.
3. Cooling Air Supply & Circulation: Clean cooling air, generated by a high-efficiency fan (with refrigeration system optional for low-temperature cooling needs), enters the cooling chamber uniformly through the airflow distribution device, forming a stable parallel or cross airflow that fully contacts the surface of the high-temperature materials on the mesh belt. The airflow direction can be adjusted to countercurrent or concurrent according to material properties and cooling requirements.
4. Heat Exchange Process: Heat from the high-temperature materials is quickly transferred to the cooling air through convection, reducing the material temperature to the specified range. The heated air is discharged from the exhaust port after heat recovery (optional) to save energy, or directly discharged after purification to avoid environmental impact.
5. Cooled Material Discharge: After continuous conveying and sufficient heat exchange in the cooling chamber, the materials that meet the specified temperature requirement are discharged from the outlet of the cooling chamber through a discharge device, completing the entire continuous cooling process. The cooled materials can be directly connected to subsequent packaging, mixing, or storage equipment for continuous production.

Key Features

• High Cooling Efficiency & Continuous Operation: Continuous conveying and uniform airflow design ensure full contact between cooling air and high-temperature materials, with a cooling rate 20-35% higher than traditional batch cooling equipment. It can realize 24-hour continuous production, greatly improving production efficiency and reducing labor intensity.
• Uniform Cooling Effect: Equipped with a professional airflow distribution device and adjustable mesh belt speed, it ensures uniform material thickness on the belt and consistent contact time between each material particle and cooling air, avoiding material temperature unevenness, deformation, cracking, or quality degradation, and ensuring stable temperature of the final cooled product.
• Energy-Saving & Environmental Protection: Adopts closed-loop airflow recycling and heat recovery technology (optional) to reuse the heat from the heated air, reducing energy consumption; the fan and refrigeration system (optional) have high energy efficiency, saving 25-30% energy compared to conventional batch cooling machines. It meets international emission standards, with no pollution to the environment, and the exhaust gas can be purified before discharge if needed.
• Strong Material Adaptability: Suitable for cooling various high-temperature materials, including powder, granular, block, sheet, strip, and even heat-sensitive materials (such as chemical intermediates, food additives, and pharmaceutical materials). The cooling speed, airflow, and mesh belt speed can be flexibly adjusted to avoid material oxidation, moisture absorption, or quality changes.
• Robust & Durable Construction: The cooling chamber and key components are made of high-grade carbon steel or stainless steel (304/316L optional), and the mesh belt is made of high-temperature resistant (up to 650°C), corrosion-resistant, and wear-resistant materials. The equipment is equipped with heat-insulating linings in key parts to reduce heat loss and adapt to harsh working environments, extending service life.
• Flexible Operation & Customization: Equipped with an intelligent PLC control system, it supports automatic adjustment of cooling temperature, mesh belt speed, airflow, and feeding speed, with real-time monitoring of operating parameters and material temperature. It can be customized in mesh belt layers (single-layer, double-layer, or multi-layer), belt width, cooling length, and cooling method (air cooling, water-cooled air cooling, or refrigerated cooling) to meet different production needs.
• Authoritative Certifications: Compliant with international standards and certified by CE (for EU market), ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System), and EX (Explosion-Proof Certification) for flammable and explosive high-temperature material cooling scenarios.
