This equipment is a low-energy, high-efficiency veneer dryer specially designed for plywood manufacturing enterprises. As the core energy-saving equipment in a plywood production line, it utilizes advanced waste-fired hot air furnace technology and high-efficiency hot air circulation systems. It can use wood processing waste such as bark, shavings, and offcuts as the main fuel, eliminating the need for auxiliary equipment like boilers and significantly reducing energy costs . The equipment is suitable for drying rotary-cut or sliced veneers (thickness range: 0.2mm-4mm). After drying, the veneers have good flatness, uniform moisture content, and are free from cracking or deformation. Compared to traditional drying equipment, this product reduces energy consumption by 75% and has a daily processing capacity of 3-7 cubic meters, making it an ideal choice for plywood factories aiming for green production and reduced operating costs .

| Mesh Belt/Roller Type Working Process |
1. Infeed Stage: Wet veneers are fed into the inlet and conveyed forward by the transport system (mesh belt or rollers) .
2. Preheating Stage: Veneers enter the front section of the heating zone and are gradually warmed up by the preheating system to prepare for rapid drying.
3. Main Drying Stage:
- Veneers are transported forward through the heating zone by multiple pairs of upper and lower rollers or mesh belts
- Circulation fans blow hot air (140-180°C) through nozzles vertically onto the upper and lower surfaces of the veneers at a speed of 1.5 m/s
- The high-velocity airflow breaks through the saturated vapor layer on the veneer surface, allowing heat to penetrate directly and moisture to evaporate rapidly
- Evaporated moisture is expelled from the machine through the moisture exhaust system
4. Cooling and Setting Stage: Dried veneers enter the cooling zone, where they are cooled by ambient air to evaporate residual moisture and set the veneer, preventing reabsorption of moisture after exiting the machine .
5. Outfeed Stage: Dried and flattened veneers are discharged from the outlet for the next process.
| Main Components |
1. Heating System
Waste-Fired Hot Air Furnace: Core energy-saving component that can use wood waste such as bark, shavings, and offcuts as fuel, eliminating the need for auxiliary equipment like boilers. It is compact, generates high heat output, and can quickly reach the required temperature for drying .
Radiators: Steel-aluminum composite radiators with large heat dissipation area and good wind resistance .
Circulation Fans: High-efficiency centrifugal fans installed on top or sides of the machine, providing large and stable airflow .
2. Conveying System
Mesh Belt Device: Stainless steel mesh belts or steel wire rope belts, equipped with infrared photoelectric deviation correction devices to prevent misalignment .
Roller Device: Upper and lower paired rollers that transport veneers through relative rotation while also providing an ironing effect .
Drive Motor: Variable frequency controlled motors for stepless speed adjustment .
3. Drying Chamber
Frame-Type Housing: Sturdy frame structure with veneer inlet and outlet .
Insulation Layer: 80-100mm thick insulation material minimizing heat loss for significant energy savings .
Heating Sections: Segmented design, each section 2-3 meters long, customizable based on capacity requirements .
4. Air Jet System
Jet Boxes/Nozzles: Precisely designed air jet boxes that evenly spray hot air onto veneer surfaces .
Air Ducts: Specially designed blow pipes ensuring uniform airflow distribution .
5. Control System
Control Cabinet: Fully automatic computer control system or PLC control .
Frequency Inverter: Internationally renowned brand inverters for precise speed control .
Sensors: Temperature sensors and humidity sensors for real-time drying monitoring.
6. Moisture Exhaust System
Exhaust Fans: Timely removal of evaporated moisture from the machine.
Exhaust Channels: Specially designed channels ensuring smooth moisture discharge .
7. Cooling System
Cooling Fans: Installed in the cooling zone for cooling and setting dried veneers .
8.Other components
| Matching Upstream and Downstream Machinery |
Low-energy plywood drying equipment works in conjunction with the following machinery in a plywood production line:
Upstream Equipment (Before Drying)
1. Rotary Lathe: Peels logs into continuous or fixed-size veneers.
Downstream Equipment (After Drying)
1. Glue Spreader: Applies glue to qualified dried veneers.
2. Cold Press: Pre-presses the assembled veneer stack for initial bonding.
3. Hot Press: Hot-presses the veneer stack into finished plywood.
4. Edge Trimmer: Trims rough edges of hot-pressed panels.
5. Sander: Sands the plywood surfaces for smooth finish.
Supporting Energy Equipment (Optional)
1. Thermal Oil Heater: Provides high-temperature thermal oil as a heat source .
2. Steam Boiler: Provides saturated steam as a heat source .
