Our "Non-destructive Drying Plywood Drying System" is an advanced drying solution specifically designed for the production of high-quality plywood and wood-based panels. Utilizing innovative low-temperature dehumidification and precise air circulation technology, the system efficiently removes moisture from within the wood while strictly controlling temperature and humidity. This fundamentally prevents common damages associated with traditional drying methods, such as cracking, warping, and internal stress.
The core advantage lies in its "Non-destructive" capability. The gentle and uniform drying process preserves the wood's natural strength, flatness, and structural integrity to the greatest extent, significantly enhancing the grade and value of the finished plywood. Equipped with intelligent fully-automatic controls, the system is energy-efficient and allows for customized drying programs based on wood species, thickness, and initial moisture content, ensuring stable and repeatable high-quality drying outcomes.
1. Low-Temperature Dehumidification Cycle:
The system operates at relatively low temperatures (typically 30-55°C). Fans drive air to circulate uniformly within the drying kiln and through the wood stacks.
Warm, humid air passes through a rotary or fixed desiccant wheel/condensation unit, where moisture is efficiently adsorbed or condensed and removed.
The dehumidified air, with significantly lowered relative humidity and enhanced moisture absorption capacity, is slightly reheated and returned to the kiln to absorb moisture from the wood.
This cycle repeats, steadily reducing the wood's moisture content without subjecting it to thermal shock.
2. Precise Environmental Control:
The system integrates high-precision temperature and humidity sensors and wood moisture content monitoring probes to monitor the kiln climate and the core state of the wood in real-time.
The PLC intelligent control system automatically adjusts heating power, dehumidifier operation, fan speed, and fresh air/recirculation air ratio based on preset drying schedules or AI-optimized algorithms.
This ensures that the temperature and humidity gradient changes throughout all drying stages (preheating, constant rate drying, falling rate drying, final conditioning) perfectly adapt to the drying characteristics of the specific wood, achieving "gentle" drying.
Component | Functional Description |
Insulated Drying Kiln Body | Constructed with sandwich color steel plates or stainless steel plates, filled with high-performance insulation material (e.g., polyurethane), ensuring minimal heat loss and excellent airtightness. |
Heating System | Typically uses efficient electric heating, hot water/steam heat exchangers, or heat pump auxiliary heating to provide a clean, controllable heat source. |
Dehumidification Unit | The core of the system, containing a desiccant wheel (adsorption type) or a compression refrigeration unit (condensation type), responsible for extracting moisture from the air. |
Air Circulation Fan System | High-power, low-noise axial or centrifugal fans ensure air moves through each layer of panels at a uniform speed and pressure, eliminating dead spots. |
Intelligent Control System | PLC + touchscreen HMI, capable of storing multiple drying schedules, enabling fully automatic operation, remote monitoring, fault alarms, and data logging. |
Loading Carts & Tracks | For carrying and transferring panel stacks, improving loading/unloading efficiency (optional depending on configuration). |
1. Loading & Inspection: Wet panels stacked according to specifications are loaded into the drying kiln, and moisture content probes are installed.
2. Schedule Selection: Select the corresponding wood species, thickness, initial/target moisture content on the control panel, or call up a custom drying schedule.
3. Automatic Operation:
Preheating Stage: The system heats up to the set point, uniformly warming the entire wood mass without intense dehumidification.
Main Drying Stage: Based on real-time monitoring data, the system automatically executes precise control of "heating-dehumidification-circulation" to gradually reduce moisture content.
Final Conditioning: At the end of drying, temperature and humidity are adjusted to balance stress between the interior and surface of the panels, relieving residual stress and improving dimensional stability.
4. Unloading & Stabilization: Once the target moisture content (typically 8%-12%) is reached, the system shuts down automatically. Panels are stabilized inside the kiln or in a storage environment before use.
