Manchurian ash (Fraxinus mandshurica) is one of the most valuable hardwood species for making high quality wood interior decoration products in China,such as parquet floor.But it is usually difficult to control the drying quality and to improve the drying productivity by using conventional drying technology due to its drying characteristics.This paper described a patented technology for drying Manchurian ash parquet floor blank.The blank was dried in a fire tube drying kiln with continuously rising temperature schedule.The test results showed that the drying speed was quick,the dried blank′s quality was good and the drying schedule was easily operated.
