Description

[0001] APPARATUS FOR DRYING AND HIGH HEAT-TREATING WOOD [0002]

The present invention relates to a wood drying and high heat treatment apparatus for drying and heat treating wood, and more particularly, to rapidly cool the heated wood through drying and high heat treatment so that the productivity of the dry and high heat treated wood is significantly improved. While the present invention relates to a wood drying and high heat treatment apparatus to prevent damage such as deformation, cracking or splitting of wood itself during indirect cooling through indirect cooling.

In general, wood has a relatively high moisture content at logging. If you make a product using the same timber as the timber, the product will be deformed over time. Thus, timber that has been cut requires an appropriate drying process.

Drying methods of wood include natural drying and hot air drying. Natural drying is a method in which wood is piled up in a drying area and drying is carried out using atmospheric temperature, humidity and wind. There is a drawback that drying time is long and a wide drying area is needed and drying is not possible below the Ki-Gun moisture content. On the other hand, hot air drying is a method of drying by artificially adjusting the drying conditions such as temperature, humidity and wind speed of the drying chamber has a relatively short drying time, there is an advantage that can be dried below the moisture content of the air.

When the wood is dried and subjected to high heat treatment, the water content is significantly lowered, the water absorption is lowered, and hemicellulose, which is a food for the bacteria, is decomposed, and it becomes difficult for the decayed bacteria to inhabit. As such, drying and high heat treatment of wood can greatly improve the durability of the wood. In recent years, wood has been used for various purposes by drying and high-temperature treatment.

The wood that has been received into the drying chamber of such wood drying and high temperature treatment apparatuses, and after being dried and superheated, must cool the wood itself to withdraw from the drying chamber. Conventionally, A method in which the chamber is opened and the heated wood is allowed to stand for a long time at room temperature for natural cooling or cooled by spraying cold or cold water on the heated wood is mainly used.

However, the above-described conventional techniques have the following problems.

As described above, in the case of naturally cooling the heated wood after drying and high heat treatment, cooling of the heated wood takes a relatively long time so that the productivity of the dried and high heat treated wood through the wood drying and high heat treatment device is significantly reduced.
