Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying treatment method for efficiently and economically removing water content of bamboo, and an apparatus for carrying out the drying treatment method. In addition, the present invention relates to a method of performing insect repellent, mildew proof, and material improvement treatment of bamboo material by replacing it with a fluid such as other gas or liquid with good workability.

[0002]

2. Description of the Related Art The conventional drying method of bamboo materials is mainly natural drying. In the case of round bamboo materials of green bamboo, they are dried in the shade in a well-ventilated shade and immersed in boiling caustic soda solution for about 20 minutes to contain the green bamboo. The round bamboo material of the oil-free bamboo whose oil and water-soluble components had been removed and the surface of which had been wiped off was dried outdoors in the sun. Other methods include a dehumidifying and drying method in which a round bamboo material is carried into a room provided with a dehumidifier and left for a predetermined date and time, and a depressurizing and drying method in which a circular bamboo material is carried into a decompression container and left for a predetermined date and time.

In addition, when the bamboo material is injected with a fluid such as a gas or a liquid in order to prevent insects, mildew and materials,
The fluid and the bamboo material were inserted into a closed container, and the inside of the container was depressurized, pressurized, or heated to impregnate the bamboo material with the required fluid.

[0004]

In the drying of the round bamboo materials such as the above-mentioned green bamboo materials and oil-free bamboo materials, the processing is often not carried out systematically due to the influence of seasonal changes and weather changes, and the drying period is To be long. This prolonged drying breaks into bamboo,
It causes mold and rot, the yield and productivity of bamboo materials decrease, and the supply of bamboo materials in line with the plan is hindered.As a result, the bamboo material processing business does not achieve stable production, and it is not possible to use this bamboo material in the next process. The influence was unavoidable. Dehumidification drying, vacuum drying, etc., proposed for the purpose of solving these problems, require a drying place and drying equipment, and although the equipment cost increases, there is little improvement in efficiency and productivity, and it is unavoidable. The fact is that the processing cost increases, the practicality decreases, and improvement is strongly desired.

The present invention eliminates the above-mentioned problems of the prior art, dries the bamboo material efficiently, economically and with good workability, and if necessary, efficiently, economically and with good workability,
An object of the present invention is to provide a bamboo material processing method and an apparatus for carrying out the method, which enables parallel processing such as insect repellent, mildew proof, and material improvement with high productivity.

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention covers one end of a sliced bamboo material with a node and covers the water in the bamboo material by sucking gas in the cover. The method for treating bamboo material, which is characterized in that it is removed from the tissue, is the first means,

[0007] Bamboo material is obtained by covering one small end of the sliced bamboo with a cover with a cover to suck gas in the cover and covering the other small end with a cover to supply fluid such as gas or liquid into the cover. The second method is a method for treating a bamboo material, characterized in that the water content of the bamboo material is removed through the passage tissue and a predetermined amount of fluid is injected.

[0008] A cover that detachably covers one small end of a round bamboo piece with knots, a vacuum pump, and an opening at one end that is in close contact with the inside of the cover, and an opening at the other end that is in close contact with the suction port of the vacuum pump. The bamboo material processing apparatus characterized by the above is the third means.

[0009]

In the present invention, since the above-described means is used, the water content of the bamboo material is forcibly sucked from one end of the pathway tissue unique to the bamboo material, which is a passageway and a teacher's canal, which are passageways for water content and nutrients. The removal of S. cerevisiae proceeds at a rate that is not comparable to the removal by dryness of the non-communicable tissue bamboo and epidermis covered with endothelium. In the present invention, a round bamboo material cut out from a bamboo grove is treated with a knotted bun, directly or after removing oil, so that the efficiency, economy, workability, and productivity are good. This is due to the fact that only the ventilation structure peculiar to the bamboo material is inhaled as a result of the cutoff of the air intake through the inside of the round bamboo material due to the felling and the knots.

This means that the cut bamboo pieces are bundled into
In other words, even if the foreheads are aligned, a cover is attached thereto as in the present invention, and even if the suction is forcibly sucked from the cover as in the present invention,
Although it is superior to the conventional example, the same effect as the present invention cannot be obtained,
It is clear from the fact that the same effect as that of the present invention can be obtained by filling the gap between the split bamboo materials with either the leading edge side or the trailing edge side of the forehead or both end sides to provide a non-ventilated state. In the latter case, it is considered that the action equivalent to that of the present invention is obtained as a result of suctioning from one end of the passageway tissue as in the present invention. In this case, the space factor of the equivalent amount of bamboo material to be treated decreases, and the packing of the transport unit is completed at the same time, but provision of a practical embedding means that reduces the required labor and time is awaited.

Injecting a fluid such as a gas or a liquid from the other end can be efficiently performed in parallel with the above-mentioned efficient removal of water. After filling the tissue, the fluid such as gas or liquid diffuses and permeates into the cells around the passageway tissue to expel the water inside the bamboo material and replace it substantially completely. Bamboo materials that are vulnerable to heat easily crack and discolor when heated, and stain the bamboo skin.
Since the boiling point of water during depressurization (in vacuum) is much lower than 100 ° C, the water inside the passageway tissue is effectively vaporized and sucked at this low temperature, and the fluid is injected, so that the soiling of the round bamboo will not occur. Disappear.
