Vacuum Kiln For Hardwood and Rosewood Drying

Rosewood and hardwood are both high density types of wood, making the drying process complicated. Conventional wood drying equipment dose not work with these, as wood will crack or become deformed in other ways. Rosewood is expensive as it is, and these deformities lead to costly losses. Jiyuan’s vacuum kiln for hardwood and rosewood is designed specifically to prevent these losses.

In 2005, utilizing our research and experience in wood drying technology, we began to combine radio frequency heating with vacuum technology. As a result, we successfully developed our radio frequency vacuum kiln or RFV kiln, which can dry wood quickly and uniformly at low temperatures. This wood drying kiln was officially put to use and introduced onto the market in 2008, making us the first radio frequency vacuum kiln manufacturer in China.

Today we are still a prominent manufacturer of vacuum wood dryers, and are still the most experienced and largest manufacturer. Our woodworking machinery comes with incomparable characteristics and advantages that will meet your requirements for drying hardwood and rosewood.
