Abstract

PROBLEM TO BE SOLVED: To eliminate a disadvantage that a crack occurs in a surface of a wood such as a conventional Japanese beech or oak of wide leaf wood due to a poor balance in drying speed between the surface of the wood and its core part when a steam drying method is applied to building material such as a column or a flat plate having a certain thickness. SOLUTION: A plate coated with resin mixed with moisture keeping agent at its surface is fixed in a drying chamber.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying room, and more particularly to a column or flat drying room for building.

[0002]

2. Description of the Related Art When a tree is dried naturally, only the surface of the tree dries and cracks occur due to the difference in the drying speed between the surface of the tree and the core.

[0003] Therefore, conventionally, in the drying of beech and oak wood of hardwood, a steam-type drying method is used, steam is produced in a boiler, the raw steam is once introduced into a drying room, and the humidity in the drying room is increased by increasing the humidity in the drying room. The wood was dried while giving moisture to the surface to prevent cracking of the surface.

[0004]

However, when the above-mentioned conventional steam-type drying method is used for building materials such as cypress and cedar, or a flat angle, cracks always occur on the surface of wood. There were drawbacks.

[0005] Therefore, low-temperature dehumidification drying is suitable for drying building materials such as pillars and flat angles.
It is not practical because it takes months.

A high-frequency drying method is also preferable, but the drying cost increases due to the problem of the amount that can be dried at one time.

The present invention has been made to eliminate the above disadvantages.

[0008]

[Means for Solving the Problems]

The drying chamber according to the present invention is characterized in that a plate coated with a resin mixed with a water retention agent is provided on the surface thereof.

Further, the drying chamber of the present invention is characterized in that a plurality of plates having a surface coated with a resin mixed with a water retention agent are arranged in a stack.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIGS. 1 to 3, a plate 2 coated with a resin 1 containing a water retention agent is adhered to the wall and ceiling in the drying chamber, and A plurality of plates 4 coated with a resin 1 containing a water retention agent on both side surfaces thereof are preferably laminated via a lining 3.

Since the drying room of the present invention is constructed as described above, when the building material is put into the drying room, the plates 2 and 4 containing the water-absorbing agent absorb the steam and moisture coming out of the building material. When the air in the drying chamber begins to dry, the moisture contained in the water retention agent of the plates 2 and 4 flows out in reverse according to the dryness of the air in the drying chamber. And it gives moisture to the drying of the surface of the building material.

Therefore, the drying speed between the surface of the building material and the core is balanced, and the building material can be dried to a moisture content of about 10% while preventing cracking of the surface of the building material.

[0015]

According to the conventional low-temperature dehumidifying and drying method, it takes too many days to dry. However, according to the drying chamber of the present invention, as described above, due to the effect of the water-retaining agent, the building material such as a pillar or a flat rectangle is not broken. Since it can be dried within a month and the water retention agent is inexpensive, there is a great advantage that the drying cost can be reduced.

The size of the drying chamber is 4 m in height and 6 in width.
m, depth 10m, it is possible to reduce the drying cost, and by arranging several drying chambers, it is possible to dry a large amount of building materials at once.

In addition, since a board coated with a resin containing a water retention agent is stuck twice in the drying chamber, the water absorption capacity is high. This water retention agent returns to its original state when dried, and can be used many times, so that it can be used effectively. In addition, long-term use is possible because recoating is possible.
