Efficient and Eco-Friendly Wood Drying with Solar Hot Air Systems 

In 2020, a wood processing factory in Chengdu, Sichuan Province, successfully implemented a solar hot air drying system designed to meet the complex and multi-stage requirements of timber drying. With drying temperatures ranging from 40°C to 90°C, the project demonstrated how solar energy can effectively replace conventional fossil fuel heating while maintaining product quality and safety.

📌 Project Overview

• Year: 2020

• Location: Chengdu, Sichuan Province, China

• Drying Temperature: 40–90°C

• System: Solar Hot Air Drying System

🌞 Why Solar Drying for Wood?

Timber drying is a critical step in the wood production process, requiring strict control of both temperature and humidity across multiple phases. Typically, initial pre-heating starts at 40–45°C, followed by gradual increases depending on the wood species and moisture content.

This project utilized a solar industrial drying solution tailored for wood applications, delivering multiple benefits:

• ✅ Stable and uniform heat distribution

• ✅ Reduced energy costs compared to traditional gas or coal systems

• ✅ Improved drying safety with no open flame or toxic emissions

• ✅ Environmentally friendly and carbon-reducing operation

🔧 Technical Highlights

The solar hot air drying system uses solar collectors to heat air, which is then circulated through the drying chambers using controlled ventilation. This approach ensures consistent drying results and high energy efficiency.

Additionally, the system is equipped with intelligent temperature and humidity sensors, allowing operators to adjust parameters in real-time and optimize drying performance across different stages.

🌱 Sustainability in Action

By adopting solar drying for wood, the Chengdu facility reduced its dependency on fossil fuels and lowered operational costs, while aligning with China’s broader goals of carbon neutrality and green manufacturing.

The success of this project proves that solar drying systems are not just viable, but highly effective for large-scale industrial applications, especially in wood processing where safety, consistency, and cost-efficiency are critical.
