Description

[0001] The present invention relates to a wood vacuum drying apparatus and a drying method,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood vacuum drying apparatus and a drying method for drying wood in a vacuum state. More particularly, the present invention relates to a wood vacuum drying apparatus and method for drying wood in a vacuum state, The water is supplied to the inside of the chamber at a high pressure to maximize the dehydration of the wood as a result of zooming and optionally to add an aqueous solution of additives such as incombustible material, salt, loess, dye, disinfectant and fragrance to the inside of the chamber, To a wood vacuum drying apparatus and a drying method in which additives can penetrate deeply into a tree to produce high quality wood having various characteristics.

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 include natural drying and hot air drying. Natural drying is a method of drying wood using the temperature, humidity and wind of the air. 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, the hot-air drying is a method of drying by adjusting the drying conditions such as the temperature, humidity and wind speed of the drying chamber relatively short in the drying time and drying, .

When wood is subjected to a drying process, water content decreases drastically and water absorption becomes low, and hemicellulose, which is food for bacteria among the constituents of wood, is decomposed, making it difficult for colostrum to live. Thus, drying of the wood can greatly improve the durability of the wood. Recently, timber has been dried and used for various purposes.

As a conventional apparatus for drying wood, for example, an apparatus in which an electric heater is directly installed in a drying chamber to heat internal air, or air heated through a hot air blower that generates heat from a combustion apparatus is introduced into a drying chamber A device for injecting the superheated steam into the drying chamber, an apparatus for injecting the superheated steam into the drying chamber, an apparatus for injecting the heated medium into the drying chamber by indirectly heating the air in the drying chamber after heating the heating medium in the combustion chamber, And a device for heating by high frequency.

In recent years, as the use of domestic wood has been increasing, it has become necessary to dry wood in the shape of a tree having a width and a width, that is, a diameter of which is relatively smaller than that of foreign wood.

Wood is widely used in various fields such as furniture, building interior, flooring, musical instrument and sculpture. Although the demand of the whole wood is increasing in the domestic market, the main raw materials are almost dependent on imports, and the supply of domestic wood is 4 To about 6%.

In other words, in terms of the forest situation in Korea, most of the trees cultivated in mountains and forests are 30-year-old or younger, small ones with a diameter of about 30 cm, and many knots and curved woods Domestic processing companies and sanitary companies mostly use imported timber or materials for their purposes such as furniture and building materials. Domestic timber is used for interior and exterior materials of wooden houses, pulp boards, railroad gangs, , Wood vinegar, etc., and the demand is in a stagnant condition.

As a result, domestic related ministries are promoting projects promoting excellence of domestic materials in order to raise awareness of Korean wood. For example, in the National Federation of Forestry Cooperatives, To donate to schools with poor environment, or to produce various kinds of wood products.

Here, the log cutting is a tree cutting to help the growth of trees, and usually has a diameter of 8 cm to 25 cm. Especially in this kind of logging, less than 1.5m in length, which is not suitable for commercial use, is discarded after being shredded. Especially, the wood is buried in forests to be destroyed through natural corrosion, processed into wood chips, or used as firewood fuel .

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

Domestic wood, which is relatively small in diameter compared to wood with a large diameter, has problems in that it is bent, bent or twisted easily in a high temperature environment during drying. Especially, since imported wood drying apparatus dries wood at a high temperature, There is a problem that deformation or discoloration of the wood easily occurs as in the case.

In addition, since the tree cuttings in domestic woods have a relatively short growth period and are highly susceptible to residual stress during drying due to a large residual stress in the wood itself during drying, deformation after drying, that is, defects such as warping, bending, .

The domestic wood has a problem in that the yield of the dried wood is remarkably lowered due to the drying defects such as deformation thereof, that is, the defective rate is increased and the productivity of the dried wood is remarkably lowered. The wood having a relatively small diameter, There is a problem that the surface of the wood is severely broken due to the difference in water content between the inside and the outside of the wood and the difference in the ambient temperature and humidity, that is, due to the abrupt change of the surrounding environment.

The present invention has been proposed in order to solve all of the above problems, and it is an object of the present invention to prevent deformation and improve strength and durability by drying the wood at a low pressure close to an extreme vacuum, The first purpose is to have it.

In addition, the hydraulic cylinder connected in two stages makes the inside of the chamber to be in a low-pressure state close to the extreme vacuum, thereby maximizing the dehydration of the wood. In addition, it is possible to maximize the dehydration of the wood and also to prevent the addition of additives such as incombustible materials, salt, A second object of the present invention is to provide a high-quality wood having various characteristics by penetrating an additive such as incombustible material, salt, loess, dye, disinfectant, fragrance, will be.
