As an alternative to the expensive and high energy consuming conventional dryers available at the market, INPA developed a solar wood dryer technically adequate to the climatic conditions of the Amazon Region, and economically suitable to an industrial segment that could not afford large investments to dry wood. The dryer has received great acceptance by the industry due to its low cost and good operating efficiency. The prototype was dimensioned with a capacity of 5 to 8 m³ of sawn wood, which is sufficient for the needs of small sawmills or furniture shops. A total of 20 units have been installed in Brazil and other countries. Research work is underway to improve the performance of the original model, and some modifications are conducted to adapt it to dry other natural products as seeds, nuts, fruits, and herbs.
