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

XUANYU Belt Drying Machine is a high-performance continuous industrial drying equipment, mainly composed of a conveying belt, drying chamber, heating system, ventilation system, and control system. It is designed to continuously vaporize and remove moisture or volatile components from various materials by conveying them through the drying chamber via a mesh belt, ensuring the final products meet specified moisture content requirements for further processing, storage, or transportation. Integrated with advanced convection heat transfer technology and uniform airflow distribution design, it features stable operation, high drying efficiency, energy conservation, uniform product quality, and strong adaptability to different material types, 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 Drying Machine adopts advanced continuous convection heat transfer technology, combined with optimized airflow distribution and multi-layer belt conveying design, to achieve rapid, uniform, and continuous drying of materials through efficient heat and mass transfer. The specific working process is as follows:

1. Material Feeding: Wet materials (in powder, granular, block, sheet, or strip form) are evenly fed into the inlet of the drying chamber through a dedicated feeding device (such as a 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 stainless steel or high-temperature resistant fabric) runs at a stepless adjustable speed, conveying materials continuously through the drying chamber. For materials requiring longer drying time, multi-layer mesh belts are adopted to extend the drying path and improve space utilization.
3. Heat Supply & Air Circulation: Clean hot air, generated by a high-efficiency heater (electric, steam, gas-fired, or heat conduction oil optional), enters the drying chamber uniformly through the airflow distribution device, forming a stable parallel or cross airflow that fully contacts the surface of the materials on the mesh belt. The airflow direction can be adjusted to countercurrent or concurrent according to material properties.
4. Heat & Mass Transfer: Heat from the hot air is transferred to the wet materials through convection, raising the material temperature and vaporizing the internal moisture. The vaporized moisture is quickly carried away by the circulating airflow, and the moist airflow is discharged from the exhaust port after being purified by a dust removal component (optional), or recycled to save energy through heat recovery.
5. Dry Material Discharge: After continuous conveying and sufficient drying in the drying chamber, the materials that meet the moisture requirement are discharged from the outlet of the drying chamber through a discharge device, completing the entire continuous drying process. The dried materials can be directly connected to subsequent processing equipment for continuous production.

Key Features

• High Drying Efficiency & Continuous Operation: Continuous conveying and uniform airflow design ensure full contact between hot air and materials, with a moisture evaporation rate 15-30% higher than traditional batch drying equipment. It can realize 24-hour continuous production, greatly improving production efficiency and reducing labor intensity.
• Uniform Drying Quality: 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 hot air, avoiding material agglomeration, deformation, cracking, or quality degradation, and ensuring stable moisture content of the final product.
• Energy-Saving & Environmental Protection: Adopts closed-loop airflow recycling and heat recovery technology (optional) to reduce heat loss; the heater has high thermal efficiency, saving 20-30% energy compared to conventional batch drying 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 drying various materials, including powder, granular, block, sheet, strip, and even heat-sensitive materials (such as herbal extracts, fruits, and vegetables). The drying temperature, mesh belt speed, and airflow can be flexibly adjusted to avoid material oxidation or decomposition, ensuring the original quality of materials.
• Robust & Durable Construction: The drying 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, corrosion-resistant, and wear-resistant materials. The equipment is equipped with wear-resistant linings in key parts, adapting to harsh working environments and extending service life.
• Flexible Operation & Customization: Equipped with an intelligent PLC control system, it supports automatic adjustment of drying temperature, mesh belt speed, airflow, and feeding speed, with real-time monitoring of operating parameters. It can be customized in mesh belt layers (single-layer, double-layer, or multi-layer), belt width, drying length, and heating method 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 material drying scenarios.
