Description

한약재의 환제조용 진공건조장치 {Vacuum drying device for making pills of chinese-crude drug}Vacuum drying device for making pills of Chinese medicine {vacuum drying device for making pills of chinese-crude drug}

본 발명은 한약재의 환제조용 진공건조장치에 관한 것으로, 액체상태의 한약재를 진공상태에서 건조시킴으로써 약효를 높일 수 있고 건조에 필요한 에너지를 줄일 수 있으며 건조시간을 단축시킬 수 있도록 된 한약재의 환제조용 진공건조장치에 관한 것이다.The present invention relates to a vacuum drying apparatus for the manufacture of medicinal herbs for medicinal herbs, by drying the medicinal herbs in a liquid state in a vacuum state to increase the drug efficacy, reduce the energy required for drying, reducing the drying time of the herbal medicine pill vacuum It relates to a drying apparatus.

통상의 치료용 또는 보약용 한약은 대개 액체상태로 조제되는 바, 다양한 재료를 한약제조장치에 넣고 고온으로 가열하면서 액을 얻고 이렇게 얻어진 액을 단위포장하여 보급하게 된다. 또, 액체상태의 한약은 부피가 클 뿐만 아니라 보관이 불편하므로 대기압상태에서 완전히 건조시켜 환(丸)으로 제조되기도 하는데, 이렇게 환으로 제조된 한약은 액체상태의 한약에 비해 먹기 편하고 약효가 높은 이점이 있다.Conventional therapeutic or remedy herbal medicines are usually prepared in a liquid state, and various materials are put into the herbal preparation device to obtain a liquid while heating to a high temperature, and the liquid thus obtained is packaged and replenished. In addition, liquid Chinese medicine is not only bulky, but also inconvenient to store, so it can be completely dried under atmospheric pressure and manufactured as a pill. The Chinese medicine made of pill is easier to eat and has higher efficacy than liquid Chinese medicine. There is this.

그러나, 통상의 한약 건조장치는 한약재로부터 액을 얻는 과정에서 장시간 동안의 가열로 인해 액이 소진될 수 있고 고압의 분위기에서 가열되므로 약효가 파괴되는 일이 빈번하게 발생되므로, 약효유지를 위해서는 처음부터 다량의 한약재를 투입하여 제조할 수 밖에 없어 한약의 값이 상승하게 된다. 또, 환으로 제조할 때에는 대개 대기압상태에서 고온건조시켜 분말로 만들게 되므로, 건조하는 데에 상당한 시간이 소요되고 건조과정 중에 온도가 과도하게 높아져 유효한 약효성분의 상당수가 파괴되며, 각종 균이 번식하기 쉬울 뿐만 아니라 에너지도 많이 소모되는 문제점이 있다.However, in the conventional herbal medicine drying apparatus, the liquid may be exhausted due to prolonged heating in the process of obtaining the liquid from the herbal medicine, and the medicine is frequently destroyed since it is heated in an atmosphere of high pressure. It is forced to manufacture a large amount of herbal medicines and the price of herbal medicines will rise. In addition, when the ring is manufactured, it is usually dried at high pressure under atmospheric pressure to form a powder. Therefore, it takes a considerable time to dry and excessively high temperature during the drying process, destroying many of the effective drug components, and propagating various germs. Not only is it easy to consume a lot of energy.

본 발명은 상기와 같은 결점을 해결하고자 안출된 것으로, 진공건조시스템을 이용하여 저온저압상태에서 한약내의 수분을 고속으로 증발시킴으로써 한약의 약효를 높이고 건조시간을 단축시키면서 건조과정 중에 균의 번식을 억제할 수 있도록 된 한약재의 환제조용 진공건조장치를 제공하는 데에 그 목적이 있다.The present invention has been made to solve the above drawbacks, by using a vacuum drying system to evaporate the water in the Chinese medicine at high temperature at low temperature and low pressure at high speed to increase the efficacy of the Chinese medicine and reduce the drying time while suppressing the growth of bacteria during the drying process. The object of the present invention is to provide a vacuum drying apparatus for the manufacture of medicinal herbs that can be made.

도 3은 본 발명 한약재의 환제조용 진공건조장치에서 액체상태의 한약재를건조시키는 과정을 설명하기 위한 흐름도로서, 도면의 왼쪽은 한약재의 건조과정에 관한 것이고 오른쪽은 수증기의 배출에 관한 것이다. 이를 참조하면, 한약재의 환을 제조하기 위한 건조과정은 건류탱크(10)내에 액체상태의 한약재를 주입하면서 시작되는데, 건류탱크(10)의 뚜껑(12)을 닫고 건조장치를 작동시키면 제 1가열수단(30)과 진공펌프(50) 등이 작동된다. 이에 따라, 가열수저장통(20)내의 가열수는 가열되기 시작하고, 가열수저장통(20)과 접촉되어 있는 건류탱크(10)내의 액체상태의 한약재가 간접적으로 가열된다. 건류탱크(10)내의 공기는 진공펌프(50)에 의해 배기되는데, 건류탱크(10)내의 압력이 진공상태가 되면 예컨대 약 15∼30mmHg의 저압과 약 15∼30℃의 저온상태에서 증발이 일어나기 시작한다. 이 때, 외부와 연통되는 건류탱크(10)의 뚜껑(12)은 건류탱크(10)를 외기로부터 완전히 밀폐시켜 진공분위기가 형성되도록 하여야 하는데, 진공펌프(50)가 작동됨과 동시에 뚜껑(12)이 자중과 중력에 의해 건류탱크(10)의 윗면에 밀착될 수 있으므로 예컨대 O-링과 같은 통상의 밀폐부재를 이용하여 쉽게 밀폐시킬 수 있다. 한편, 진공펌프(50)에 흡입되는 수증기가 윤활유와 섞이면 윤활유의 점도가 낮아져 고장의 원인이 될 수 있으므로, 진공펌프(50)로 이동되는 수증기를 증발시킬 수 있도록 건류탱크(10)와 진공펌프(50)의 사이에 제 2가열수단(40)을 설치하여 수증기의 응축을 방지하는 것이 바람직하다. 한편, 진공펌프(50)는 기/액분리탱크(60)와 연결되어 있는데 이들 사이에 응축기(도시되지 않음)를 설치하여 진공펌프(50)를 통과하는 수증기를 응축시킴으로써 기체와 액체를 분리할 수 있으며, 분리된 기체는 배출구(62)를 통해 건조장치의 밖으로 배기되고 액체는 기/액분리탱크(60)의 바닥에 형성된 배수통로(도시되지 않음)를 통해 배수된다.Figure 3 is a flow chart for explaining the process of drying the herbal medicine in a liquid state in the vacuum drying apparatus for the manufacture of pills of the present invention, the left side of the figure relates to the drying process of the herbal medicine and the right side relates to the discharge of water vapor. Referring to this, the drying process for manufacturing the medicinal herb ring is started by injecting the liquid medicinal herb in the distillation tank 10. When the lid 12 of the distillation tank 10 is closed and the drying apparatus is operated, the drying process is performed. The means 30 and the vacuum pump 50 and the like are operated. Accordingly, the heating water in the heating water storage tank 20 starts to heat, and the herbal medicine in the liquid state in the distillation tank 10 in contact with the heating water storage tank 20 is indirectly heated. The air in the distillation tank 10 is exhausted by the vacuum pump 50. When the pressure in the distillation tank 10 becomes a vacuum, evaporation occurs at a low pressure of about 15 to 30 mmHg and a low temperature of about 15 to 30 ° C, for example. To start. At this time, the lid 12 of the distillation tank 10 in communication with the outside should completely seal the distillation tank 10 from the outside air to form a vacuum atmosphere, the vacuum pump 50 is operated and at the same time the lid 12 This self-weight and gravity can be in close contact with the upper surface of the distillation tank 10, so that it can be easily sealed using a conventional sealing member such as, for example, an O-ring. On the other hand, if the water vapor sucked into the vacuum pump 50 is mixed with the lubricating oil, the viscosity of the lubricating oil may be lowered, which may cause a failure. It is preferable to provide a second heating means 40 between the 50 to prevent condensation of water vapor. On the other hand, the vacuum pump 50 is connected to the gas / liquid separation tank 60, a condenser (not shown) is installed between them to condense the water vapor passing through the vacuum pump 50 to separate the gas and liquid The separated gas is exhausted out of the drying apparatus through the outlet 62 and the liquid is drained through a drain passage (not shown) formed at the bottom of the gas / liquid separation tank 60.

이상에서 설명한 본 발명은 상기 실시예에만 한정되는 것은 아니고, 첨부되는 청구범위에 의해 개시되는 본 발명의 범위내에서 다양한 응용예 및 변경예를 통해 실시할 수 있음은 물론이다.The present invention described above is not limited only to the above embodiment, but can be practiced through various applications and modifications within the scope of the invention disclosed by the appended claims.

상기와 같은 본 발명에 의하면, 진공건조시스템을 이용하여 저온저압상태에서 한약내의 수분을 고속으로 증발시킴으로써 한약의 약효를 높이고 건조시간을 단축시키면서 건조과정 중에 발생할 수 있는 균의 번식을 억제할 수 있을 뿐만 아니라, 다량의 약재를 투입하지 않아도 되므로 제조단가도 낮출 수 있다.According to the present invention as described above, by using a vacuum drying system to evaporate the water in the herbal medicine at high temperature at low temperature and low pressure at high speed, it is possible to suppress the growth of bacteria that can occur during the drying process while increasing the efficacy of the herbal medicine and shortening the drying time. In addition, the manufacturing cost can be lowered because a large amount of medicine does not need to be added.
