Abstract
A method for making wood with heartwood has steps of forming a wood log with a heartwood from a tree, pressure treatment to the wood log with the heartwood, drying the wood log and forming the wood log to a desired shape. The pressure treatment process is to apply a desired pressure to the wood log to reduce a moisture content of the wood log with the heartwood to an even level. This can avoid the wood log with the heartwood to split, crack or deform during the drying process. The utilization of a tree can be increased, and the process for gain a wood material is simplified.
Claims8
A method for producing timber with heartwood comprising steps follow:
- forming a piece of timber including a heartwood from a tree;
- pressure treatment of the piece of timber including the heartwood, wherein a desired pressure is applied to the piece of timber to reduce a moisture content of the piece of timber including the heartwood to a level consistent throughout the piece of timber and the heartwood;
- drying the piece of timber including the heartwood to reduce the moisture content of the piece of timber including the heartwood to a desired level;
- and
- forming the piece of timber including the heartwood to a desired shape,
- wherein to provide the desired pressure to the piece of timber including the heartwood, multiple pressing plates are arranged around the piece of timber including the heartwood and abut an outer periphery of the piece of timber including the heartwood;
- and
- a pressure source is application to each pressing plate to compress the piece of timber including the heartwood.
