Description

Timber drying apparatus

The present invention relates to a drying apparatus, and more particularly, by storing and rotating the dyed patterned wood board material can be dehydrated by centrifugal force to shorten the drying time to improve the productivity, and prevent distortion caused during conventional natural drying And it is possible to improve the quality by reducing the defect rate by minimizing, and relates to a wood drying apparatus that can reduce the amount of power used compared to the conventional high frequency vacuum dryer.

In general, the moisture content of the wood depends on the type of wood and the seasonal conditions at the time of cutting, but contains approximately 28 to 60% by weight.

In order to commercialize such wood, it is cut to a certain size, and then processed into a pattern wood board through dyeing, chemical treatment, and drying. The processed wood board is mainly used for manufacturing furniture, interiors, automobiles, and ships.

Here, the method of dyeing wood veneer is to dye and mix water and chemicals in a water tank, and to dye by dipping wood veneer in this mixture, and to accommodate a large amount of wood veneer in a water tank, dye, water and chemicals are mixed. An apparatus for dyeing a large amount of pattern wood board material by circulating the mixed solution inside the tank has been developed and used.

Dyeing and chemically treated wood veneer needs to reduce the moisture content within the range of 5% to 15% by weight as much as possible, and is then dried.

Here, the dyeing process is to increase the moisture content of the pattern wood board material, there is a problem that takes 3 to 5 times the drying time than the natural wood board material.
