Wood drying subsequently attains equilibrium with the surrounding air in moisture content.
| FactSnippet No. 1,596,582 |
Rate of Wood drying largely depends on climatic conditions, and on the air movement.

Significant advantages of conventional kiln Wood drying include higher throughput and better control of the final moisture content.
| FactSnippet No. 1,596,585 |
The Wood drying conditions are successively varied according to the type of timber being dried.
| FactSnippet No. 1,596,586 |
Freeze drying is accomplished by lowering the pressure in a chamber containing the wood to a few millibars, while lowering the temperature of the chamber to below the eutectic point of the material.
| FactSnippet No. 1,596,587 |
An advantage of freeze drying wood is that the form of the wood is maintained, and shrinkage does not typically occur.
| FactSnippet No. 1,596,588 |
Newer wood drying technologies have included the use of reduced atmospheric pressure to attempt to speed up the drying process.
