PCT No. PCT/SE89/00412 Sec. 371 Date Dec. 20, 1990 Sec. 102(e) Date Dec. 20, 1990 PCT Filed Jul. 13, 1989 PCT Pub. No. WO90/00713 PCT Pub. Date Jan. 25, 1990.The invention relates to the drying of veneer and similar products. It provides a solution to the problem of such products, after having passed through a hot air drier, exhibiting local areas having an intolerantly high moisture content-they are "underdried". According to the invention those areas are dried with microwave energy. The products (4) pass through the near field of the microwave energy present as standing waves in transverse ducts (6) also supplying the hot air and having openings (11) through which the microwave energy is tapped. Together they cover all of the adjacent product surface, but energy is only tapped through those of them past which underdried areas travel. |
