The core of the system involves using saturated steam generated by a boiler to heat the air inside the drying chamber via an efficient heat exchanger (radiator). Powered by high-pressure centrifugal fans, a uniform and stable flow of hot air circulates horizontally or vertically. This hot air penetrates the stacked plywood, efficiently removing moisture through convective heat transfer. The moist air is then continuously exhausted by a dehumidification system while fresh, dry air is introduced. This creates a consistent and controllable drying environment within the chamber, ensuring the plywood dries evenly from the inside out, effectively preventing deformation, cracking, and mold.

1. Main Structure

Drying Chamber: A large, well-sealed chamber or tunnel with internal insulation (e.g., rock wool) to prevent heat loss and improve energy efficiency.

Main Door: A sturdy, sealed door for loading and unloading the plywood.

2. Heating System:

Steam Pipeline: Includes main steam pipes, control valves, steam traps, etc.

Radiators (Finned Tube Heat Exchangers): The core heating components, typically installed at the top, bottom, or side walls of the drying chamber.

3. Ventilation System:

Circulation Fans: Usually axial or centrifugal fans that provide strong airflow to ensure even distribution of heat and humidity.

Air Ducts / Baffles: Scientifically designed ducts and baffles guide the hot air to flow optimally through the plywood stacks.

4. Moisture Exhaust System:

Exhaust Vents / Dampers: Their opening can be adjusted automatically or manually.

Exhaust Fans: Used to force the expulsion of humid hot air.

5. Control System:

PLC (Programmable Logic Controller) and Touch Screen: The brain and operation interface.

Temperature & Humidity Sensors: Monitor environmental parameters inside the chamber in real-time.

Actuators: Such as electric steam valves, exhaust damper actuators, etc., which act on commands from the PLC.

6. Loading System:

Drying Carts / Drying Racks: Used to stack the veneers/plywood into piles, which are then pushed into the drying chamber on carts.

  High Efficiency & Energy Saving: Steam is a relatively low-cost heat source. Combined with efficient heat exchange and superior insulation, the overall energy consumption is far lower than traditional electric or oil-fired heating methods.

  Environmentally Clean: Using steam as the heat medium produces no flue gas or harmful emissions during operation, complying with strict environmental standards.

  Exceptional Drying Quality: Uniform air circulation ensures synchronous moisture evaporation from both the surface and core of the plywood. The dried boards exhibit high flatness, low internal stress, and are effectively prevented from warping and cracking, significantly improving product yield.

  High Automation: Features one-button start/stop and fully automatic process control, reducing reliance on operator experience and ensuring the repeatability and consistency of the drying process.

  Wide Applicability: Can be customized in different sizes and capacities according to client needs. Suitable for drying plywood made from various wood species such as poplar, pine, eucalyptus, and mixed hardwoods.

This equipment is widely used in large, medium, and small-scale plywood manufacturing plants, wood industry companies, and timber processing factories. It is a key piece of equipment for producing high-quality construction templates, furniture-grade plywood, decorative panels, and other related products.
