Conventional Wood Drying Kiln
Conventional Wood Drying Kiln
TECH Conventional Wood Drying Kiln (ZQ Series) is a versatile dryer. It can use steam, hot water, thermal oil, or electricity as the heating medium, operating at a drying temperature of 100℃ (212℉) or less. This makes it suitable for both softwood and hardwood, meeting various wood processing needs.
Our ZQ series kiln dryers, installed in 46 countries worldwide, are remarkable for their reliability and high efficiency. Our innovative technology precisely controls the drying process. This reduces lumber drying defects and ensures faster, more uniform drying, delivering high – quality results for our customers.

Key Features
Robust Construction
Kiln chamber walls constructed with rust-proof 3003 aluminum; main structure built with 6063 aluminum. Heat exchanger pipes and all connecting parts feature 304 stainless steel, ensuring leak-free operation. Modular design enables easy maintenance. Ferrous-free structure guarantees 20+ years of corrosion resistance and stability.
Optimal Moisture Control
The automatic control system enables precise regulation of temperature and humidity within ±0.5°C. It has remote-control and real-time data management functions, ensuring user – friendliness, as well as high efficiency and energy conservation.
Drying Technology
Over the 25+ years, TECH has scientifically engineered wood drying through rigorous species-specific research. Our multiphase drying protocols, validated via 10,000 in-lab tests, dynamically adjust to each species’ unique moisture diffusion and shrinkage patterns, cutting defects by 40%.
Integrated Design
The kiln comprises six main systems: the heating system, the spraying system, the air circulation system, the venting system, the kiln door system, and the automatic control system.

System Design of Kilns
Air Circulation System
✅ Alluminum and Reversible Fans: All aluminum, fully reversible fans that alternate direction to eliminate stagnant air zones and promote consistent humidity distribution.
✅ Integrated Baffling: Directs airflow through lumber stacks rather than around them, maximizing contact and wood drying efficiency.
✅ High Temperature & Humidity Resistance Motors: Internal motors with thermal insulation and corrosion-resistant casing for 100°C/100%RH kiln environments; Optional external motor systems tailored to specific airflow and environmental needs.
Heating System
✅ Robust Material Construction: Base pipes of heat exchanges, in-kiln pipelines, and all connecting parts are crafted from stainless steel, ensuring superior leak resistance and long-term durability.
✅ High-Pressure/Temperature Capability: The heat exchanger is rated for safe continuous operation at 1.27 Mpa under steam heating conditions.
Smart Control System
✅ Precise Monitoring
Equipped with multiple high-accuracy sensors to track in-kiln temperature, humidity, and moisture content.
✅ Automatic Control
The TECH PLC system automatically evaluates and executes based on sensor data and preset schedules, maintaining ±0.5°C temperature/humidity precision for optimal drying uniformity.
✅ Remote Management
The control system features a touch screen. Also, it enables remote control and real-time data monitoring via mobile/PC devices, reducing manual inspections by 60%.
Integrated Design
The kiln comprises six main systems: the heating system, the spraying system, the air circulation system, the dehumidification system, the kiln door system, and the automatic control system.
- Heating System: Equipped with a high-temperature and high-pressure resistant heat exchanger. It can operate continuously under 1.27 Mpa when using steam heating.
- Spray System: Equipped with spray electric valves from a German brand. The spray pipes are made of ASTM 304 stainless steel, featuring high corrosion resistance and reliability.
- Air Circulation System: A symmetrical fan system ensures uniform air circulation in the duct. Fitted with an OEM aluminum – alloy fan and an insulated motor, it withstands 120°C and 100% humidity. This efficient air – flow keeps wood moisture content even for uniform drying.
- Venting System: Features Siemens electric damper actuators, compact and reliable. Aluminum gate – plate dampers offer low resistance, light weight and corrosion resistance
- Kiln Door System: It features excellent thermal insulation, is lightweight, corrosion – resistant and aging – resistant.
