1. Continuous Transmission System: Utilizes a frequency conversion speed control motor to drive rollers or chains, ensuring smooth and adjustable speed operation for 24/7 uninterrupted production.
2. High-Efficiency Heating System: Compatible with multiple heat sources (steam, natural gas, biomass, electricity, heat pumps), offering high thermal efficiency and controllable operating costs.
3. Intelligent Control System: The core component. Employs a PLC and an HMI touchscreen interface for precise setting and real-time monitoring of temperature, humidity, air velocity in each zone, and the transport speed. Pre-set drying schedules can be selected with one click for automated operation, minimizing human error.
4. High-Strength Insulated Kiln Body: Constructed with premium insulation materials (e.g., rock wool, polyurethane) and sealing technology, drastically reducing heat loss and ensuring a stable thermal environment inside the kiln.
5. Forced Circulation System: Comprises high-flow, high-pressure heat-resistant fans and scientifically designed air ducts to ensure hot air penetrates every veneer sheet uniformly and intensely, eliminating any drying dead spots.
6. Heat Recovery System (Key Energy-Saving Component): A heat exchanger transfers thermal energy from the outgoing hot, humid exhaust air to the incoming fresh, cold air, pre-heating it. This can save over 20%-30% in energy consumption.
IV. Key Technical Advantages
Energy Efficiency & High Performance: Heat recovery technology and high-efficiency insulation drastically reduce energy consumption per unit of product, offering significant energy savings compared to traditional batch-type kilns.
Superior Drying Quality: Uniform and stable air circulation combined with precise temperature and humidity control effectively prevents cracking, warping, and deformation of plywood, increasing product yield and grade.
High Automation Level: Fully automated process control greatly reduces reliance on operator skill and experience, lowering labor intensity and costs.
High Production Efficiency: Continuous loading and unloading enable a fast production pace and massive output, making it ideal for large-scale, centralized production.
Environmentally Friendly: The use of clean energy options and high-efficiency combustion reduces exhaust emissions, complying with environmental regulations.
Primarily used in the drying process of production lines for plywood, blockboard, particleboard, MDF, and other wood-based panels. It can also be used for drying other sheet materials like wood and bamboo.
