- Process for packing and drying solid wood and a plant for accomplishing same
- (57) Abstract
A process for packing and drying solid wood, wherein the wood is treated with ammonia at elevated temperatures and under pressure, and simultaneously packed, thereby producing wood which features uniform density over its entire cross section. A plant for accomplishing the process of the invention, which helps simultaneously effect in a single chamber both ammonia treatment and forced packing.

Claims (3)
- A plant for packing and drying wood comprising: a hermetically sealed heated chamber including walls; at least one vertically extending power cylinder on one of said walls of said chamber; said power cylinder including a rod having a free end protruding inside said chamber; a press plate on said free end; a press table inside said chamber and adapted for the piling thereon of the wood being treated; a source of ammonia and an apparatus for the pressure feed of ammonia; a pipeline connecting said chamber with said apparatus for the pressure feed of ammonia to the chamber; and a fan to effect forced circulation of the gaseous medium inside said chamber.
- A process as claimed in claim 1 wherein the pressure applied to the wood is about 0.1 to 12 kg./sq.cm.
- A process as claimed in claim 3 comprising placing the wood in a chamber, evacuating the chamber, feeding gaseous ammonia to the chamber, adding steam to the chamber, and actuating a fan in the chamber.
