Description

대나무 균열 방지 건조방법{METHOD FOR DRYING A BAMBOO WITHOUT FORMATION OF SPLITS}Bamboo cracking drying method {METHOD FOR DRYING A BAMBOO WITHOUT FORMATION OF SPLITS}

본 발명은 대나무 균열 방지 건조방법에 관한 것으로, 보다 상세하게는 대나무 건조시 대나무에 균열이 일어나는 것을 방지하여 죽제품의 활용도를 높이고, 죽공예산업을 주축으로 하는 지역경제에 많은 도움을 주기 위한 대나무 균열 방지 건조방법을 제공하는 데 있다.The present invention relates to a bamboo crack prevention drying method, and more specifically, to prevent cracking in the bamboo during drying bamboo to increase the utilization of bamboo products, bamboo cracks to help a lot of local economy mainly in bamboo craft industry It is to provide a prevention drying method.

대나무(竹)는 성장이 매우 빠르고, 생명력과 번식력이 강하여 그 자원이 풍부한 편이다. Bamboo (竹) is very fast growing, vitality and strong fertility is rich in resources.

특히 다른 목재와 달리 내부에 적정한 공간이 형성된 통체의 형상인 것을 특징으로 하고 있으며, 부후균(腐朽)에 대한 저항성이 뛰어나다.In particular, unlike other wood, it is characterized by the shape of a cylindrical body formed with an appropriate space therein, and excellent resistance to fungi (腐朽).

이러한 점 때문에 대나무를 대금, 피리를 비롯한 다양한 형태의 관악기재, 조미료통, 연필통, 고급차(茶)통 및 주류통 등과 같은 용기류 용재 또는 의자나 조명기구 등과 같은 소품가구의 부재 등으로 이용하고자 하는 시도가 끊임없이 계속되어 왔다. For this reason, attempts to use bamboo as a material for containers such as Daegeum, Flute, various forms of wind instruments, seasonings, pencils, high-quality tea and liquor cans, or the absence of accessory furniture such as chairs and lighting fixtures Has been constantly going on.

특히 대나무 서식지는 태양광선의 지표면 투입이 불량하여 지하림(地下林)이나 지표식물의 생육이 곤란한 점 때문에 생물의 다양성을 주장하는 환경론자들에 의해서 대나무 벌채론이 강하게 제기되고 있는 실정이다. 이러한 점에서 대나무의 이용도를 제고하는 것은 그 의의가 있다.In particular, bamboo habitats have been strongly suggested by environmentalists who claim biodiversity because of poor input of sunlight on the ground, making it difficult to grow underground forests or surface plants. In this sense, it is meaningful to improve the utilization of bamboo.

그러나, 통대나무의 경우 건조 중 외피면이 내피면보다 먼저 섬유포화점(함수율 약 30%)에 도달하면서 건조 초기에 외피면에 미세한 쪼개짐이 발생하고, 건조후기에는 통대나무의 접선방향과 방사방향간의 수축율 차에 의해서 형성되는 이방성수축응력이 미세 쪼개짐 부위에 집중되면서 쪼개짐은 통대나무의 전 부위로 더욱 크게 확장되어 대나무를 통상(筒狀)으로 이용하는 것이 곤란하게 된다.However, in case of bark wood, the outer skin surface reaches the fiber saturation point (water content of about 30%) before drying and fine splitting occurs on the outer skin surface at the beginning of drying. As the anisotropic shrinkage stress formed by the difference in shrinkage rate is concentrated in the minute cracking area, the cracking is further extended to the entire area of the bamboo tree, making it difficult to use bamboo as a normal.

따라서, 종래에는 2∼3개월에 걸쳐 실내에서 서서히 음건(陰乾)하거나, 일부에서는 통대나무에 약제를 주입한 후 인공건조하여 사용해 오고 있었다. Therefore, in the past, it has been slowly dried in the room for 2 to 3 months, or in some cases artificially dried after injecting a medicine into the barrel and used.

그러나, 실내 음건의 경우 일차적으로 무결점의 통대나무를 얻는 것 자체가 어려울뿐 아니 라, 건조에 매우 오랜 기간이 소요되며, 무결점의 통대나무라 할지라도 죽제품이 사용되어질 실내의 함수율까지 건조되지 않으므로써 실제 사용 중에 쪼개지는 문제가 발생하는 등 산업성이 떨어지는 문제점이 있다. However, in the case of indoor shade, it is not only difficult to obtain a defect-free barrel, but also it takes a very long time to dry, and even a defect-free barrel does not dry up to the moisture content of the room where bamboo products are used. There is a problem that the industry is inferior, such as the problem of splitting during use.

또한 약제를 주입하여 인공건조하는 경우는 대나무의 표층에 형성되어 있는 왁스층 때문에 약제주입이 곤란하므로써 약제주입에 소요되는 시간과 장치비용의 문제로 경제성이 떨어지고, 음식물 용기나 신체와의 접촉이 이루어지는 죽제품에 사용할 수 없는 용도제약이 있으며, 쪼개짐을 예방하는데 효과가 크지 않은 문제점이 있다.In addition, in case of artificial drying by injecting drugs, it is difficult to inject drugs due to the wax layer formed on the surface of bamboo. There is a pharmaceutical use that can not be used in, there is a problem that is not effective in preventing splitting.

다시 말해, 통대나무의 경우 적절한 간격으로 형성되어 있는 마디에 의해서 마디와 마디 사이에 밀폐된 공간이 만들어져 있고, 건조시 대나무 외피면에서 증발된 수분은 대기중으로 방출되지만 내피면에서 증발된 수증기는 이 밀폐된 공간에 머무르게 되어 높은 수증기압이 형성되게 되어 내피면과 내피면사이의 수분경사가 급격하여 외피가 쪼개지는 현상이 발생하는 문제점이 있다.In other words, in the case of bark wood, the space between the nodes is made by the nodes formed at appropriate intervals, and when evaporated, moisture evaporated from the bamboo skin surface is released into the atmosphere, but water vapor evaporated from the inner surface As a result of staying in a closed space, a high water vapor pressure is formed, and the water inclination between the endothelial surface and the endothelial surface suddenly causes the skin to split.

본 발명은 상기한 문제점을 해결하기 위하여 창안된 것으로, 보다 상세하게는 대나무를 균열이 없이 안정적으로 건조생산할 수 있으며, 건조시간의 단축으로 인해 건조생산비 절감할 수 있고, 죽제품의 활용도를 높이기 위한 대나무 균열 방지 건조방법을 제공하는 데 있다.The present invention was devised to solve the above problems, and more specifically, it is possible to stably dry and produce bamboo without cracking, and to reduce drying production costs due to a shortening of drying time, and to increase the utilization of bamboo products. It is to provide a crack-proof drying method.

상기의 목적을 달성하기 위한 본 발명의 구성은, 대나무 건조시 대나무에 균열이 발생하는 것을 방지하기 위한 대나무 건조방법에 있어서, 대나무를 일정한 길이로 절단하는 대나무준비단계와; 상기 대나무의 내측에 형성된 마디부분을 제거하는 마디제거단계와; 상기 단계를 거친 대나무를 가열 건조시키는 건조단계로 구성되는 것을 특징으로 한다.The configuration of the present invention for achieving the above object, in the bamboo drying method for preventing the occurrence of cracks in the bamboo during bamboo drying, bamboo preparation step of cutting the bamboo to a certain length; A node removing step of removing a node portion formed inside the bamboo; Characterized in that it comprises a drying step of heating and drying the bamboo after the step.

상술한 바와 같이 본 발명에 따르면, 대나무에 형성되어 있는 마디를 제거하여 매듭의 형성된 부분에서의 강도차와 매듭이 형성되어 있지 않은 부분에서의 강도차를 줄임으로써 건조시 강도차에 따른 균열을 방지할 뿐 아니라 공기이동이 자유롭게 이루져 외피와 내피간의 수분증발량이 동일하게 되어 대나무에 균열이 생기지 않아 죽제품으로써의 활용도가 높아지며, 죽공예산업의 발전에 기여하게 되어 지역경제에 도움을 줄 수 있는 효과가 있다.As described above, according to the present invention, by removing the nodes formed in the bamboo to reduce the strength difference in the portion where the knot is formed and the strength difference in the portion where the knot is not formed to prevent cracks due to the strength difference during drying In addition, the air movement is free and the water vaporization between the outer skin and the inner skin is the same, so that there is no crack in bamboo, so the utilization of bamboo products becomes higher, and it contributes to the development of bamboo craft industry, which helps the local economy. There is.

이하에서는 본 발명의 대나무 균열 방지 건조방법을 상세히 설명한다.Hereinafter, the bamboo crack prevention drying method of the present invention will be described in detail.

도 1은 본 발명에 따른 대나무 균열방지 건조방법를 나타낸 블록도이다.1 is a block diagram showing a bamboo crack prevention drying method according to the present invention.

상기 도 1에 도시된 바와 같이, 본 발명에 따른 대나무 균열방지 건조방법은 대나무준비단계와, 마디제거단계와, 건조단계로 구성된다.As shown in FIG. 1, the bamboo crack prevention drying method according to the present invention includes a bamboo preparation step, a node removing step, and a drying step.

대나무준비단계는 대나무를 제품으로 생산하여 사용하고자 하는 용도에 따라 다양한 길이를 갖는 상태로 절개하는 단계로, 예를 들어 근래에 대나무를 이용하여 울타리를 제작할 경우에는 울타리 설치면적이나 크기에 따라 대나무를 적당한 길이로 절개하여 준비하거나, 관악악기 또는 조미료통과 같은 곳에 대나무를 이용할 경우에는 대나무의 직경이 작은 것을 골라 적당한 길이로 절단하는 것을 의미한다.The bamboo preparation step is to cut the bamboo into various lengths according to the purpose of producing and using the bamboo as a product. For example, in the case of making a fence using bamboo in recent years, bamboo is made according to the fence installation area or size. When preparing by cutting to a suitable length, or using bamboo in a wind instrument or seasoning container, it means to choose a small diameter of bamboo and cut it to a suitable length.

이후, 상기 대나무준비단계를 거친 대나무를 일정한 기계장치나 도구를 이용하여 대나무 내측 마디부분을 제거한다. Thereafter, the bamboo after the bamboo preparation step is removed by using a certain machinery or tools to the inner portion of the bamboo.

이렇게 대나무의 내측마디부분을 모두 제거함으로써 일측개구부와 타측개구부가 뚫린 중공형의 대나무가 되는 것이다.By removing all of the inner section of the bamboo in this way will be hollow bamboo with one opening and the other opening.

그 후, 대나무를 가열장치를 이용하여 가열 건조시키게 되는데, 상기 가열장치 특정한 건조가열장치에 한정하지 않으나, 바람직하게는 가열과 동시에 대나무 외피면에서 증발된 수분을 제거하기 위해 송풍기가 설치된 건조용 송풍가열장치를 사용하거나 가열과 동시에 대나무 외피면에서 증발된 수분을 제거하기 위한 진공펌 프가 설치된 진공가열장치를 사용하는 것이 바람직하다.Thereafter, the bamboo is heated and dried using a heating apparatus, but the heating apparatus is not limited to a specific drying heating apparatus, but preferably, a drying blower provided with a blower to remove moisture evaporated from the bamboo skin surface simultaneously with heating. It is preferable to use a heating apparatus or a vacuum heating apparatus equipped with a vacuum pump for removing moisture evaporated from the bamboo skin surface at the same time as heating.

여기서, 본 발명의 건조방법은 대나무의 특정한 산지, 대나무의 직경과 길이에 국한되는 것이 아니며, 건조시간경과별 가열온도 상승방법 또는 진공도 등은 대나무의 재질 특성이나 생산자의 생산계획에 따라 다소 달라질 수 있음을 밝혀두는 바이다.Here, the drying method of the present invention is not limited to a specific production area of bamboo, the diameter and length of the bamboo, the heating temperature rising method or vacuum degree by drying time may vary somewhat depending on the material properties of the bamboo or the production plan of the producer It is to be noted.

상기와 같이 대나무의 내측 마디부분을 제거함으로써 건조시 공기의 흐름이 원활하여 대나무에 균열이 생기지 않게 되며, 건조시 대나무 내피에서 증발된 수분이 원활하게 대나무의 외측으로 빠지게 됨에 따라 대나무의 외피와 내피간의 증발수분량이 일정하게 유지됨으로써 대나무의 균열이 일어나지 않게 된다.By removing the inner node of the bamboo as described above, the air flows smoothly during drying so that no cracks occur in the bamboo, and the moisture evaporated from the bamboo endothelium smoothly falls outward to the outside of the bamboo. Since the amount of evaporated water in the liver is kept constant, bamboo cracking does not occur.

그로 인해, 건조된 대나무의 활용도가 높아져 죽공예산업을 주축으로 하는 지역경제에 많은 도움을 줄 수 있는 효과가 있다.As a result, the utilization of dried bamboo is increased, which can help the local economy mainly based on the bamboo craft industry.

이와같이, 본 발명에 관해 상세히 설명하였으나, 본 발명이 속하는 분야에 통상의 지식을 갖는 자라면 본 발명의 범주에서 벗어나지 않는 범위에서 다양한 변형실시가 가능할 것이다.As described above, the present invention has been described in detail, but those skilled in the art to which the present invention pertains may make various modifications without departing from the scope of the present invention.

그러므로, 본 발명의 범위는 상술한 실시예에 한정되지 않고, 후술하는 특허청구범위뿐만 아니라 이 청구범위와 균등한 것들에 의해 정해져야 할 것이다.Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be defined by the claims below and equivalents thereof.
