본 고안의 외부 공기를 흡입하여 가열 송풍하므로서 각종 농수산물의 피건조물을 건조시키는 데 사용하는 열풍 건조기에 관한 것으로, 건조기 본체를 구성할 때 건조실 하측에 착설되는 다공철판의 하부 에는 여러개의 풍량조절 안내판을 착설하고, 그 하측에는 열풍실을 2중 구조로 형성하며, 열풍실의 유입구에는 풍량조절 댐퍼를 착설하여서 되는 것이다.The present invention relates to a hot air dryer used to dry a dried product of various agricultural and aquatic products by sucking and blowing air outside, and a plurality of air volume control guide plates are provided at a lower part of a porous iron plate installed below the drying chamber when the dryer body is constructed. It installs, and the lower part of a hot air chamber is formed in a double structure, and the air volume control damper is installed in the inlet of a hot air chamber.

종래의 열풍 건조기는 하측에 열풍실을 하나만 형성하였기 때문에 열풍의 온도 및 풍량을 조절할수 없었기 때문에 피 건조물인 각종 농수산물의 건조말기에 적절한 열풍의 온도와 풍량을 공급하지 못하고 과다하게 공급하므로서 피건조물의 갈변현상을 유발시켰을 뿐만 아니라, 과다한 열풍의 온도와 풍량에 따른 열원에너지의 낭비가 많았던 것이다.In the conventional hot air dryer, since only one hot air chamber was formed at the lower side, the temperature and air volume of the hot air could not be controlled. Therefore, the hot air dryer did not supply an appropriate amount of hot air temperature and air volume at the end of drying of various agricultural and aquatic products. Not only did it cause browning, but there was a lot of waste of heat source energy due to excessive temperature and air volume of hot wind.

일반적으로 피건조물에 함유된 수분을 제거하여 말리는 건조는 건조과정에 따라서 항률건조기간과 감률건조기간으로 구분되는데 피건조물중에는 곡류나 고추의 경우와 같이 항률건조기간이 없는 것이 있을 뿐만 아니라, 무우 말랭이의 경우와 같이 향률건조기간이 길고 감률건조기간은 짧은 것이 있으므로 각종 농수산물등과 같이 다양한 피건조물을 건조할때 사용하는 열풍건조기는 열풍의 온도와 습도 및 풍량이 매우 중요한 것이다.In general, drying by removing moisture contained in the dried product is divided into the period of constant drying and the rate of drying according to the drying process. Among the dried products, there is no constant drying period as in the case of cereal or red pepper, and radish dried As in the case of the long period of drying rate of flavor and short period of drying rate of deceleration, the hot air dryer used to dry various dry matters such as various agricultural and marine products is a very important temperature, humidity and air volume of the hot air.

특히, 건조된 피건조물을 분쇄하거나 장기 저장시킬 목적으로 수분함량이 5%이하의 매우 낮은 상태로 건조하는 방법을 빈(Bin)건조라고 하며, 이 빈 건조에는 일정온도하에서 적은 풍량을 필요로 하고 있는 것이다.In particular, the method of drying the dried items to a very low moisture content of less than 5% for the purpose of pulverizing or storing for a long time is called Bin drying, which requires a small amount of air at a certain temperature. It is.

그러나, 종래의 열풍 건조기는 일정한 모터에서 공기가 송풍되고 있으므로서 건조 초기에는 많은 부피를 갖는 피건조물에 의하여 풍압이 높아져서 적은 양의 공기가 송풍되고, 피건조물의 건조가 진행됨에 따라서 피건조물의 부피가 줄어들어 풍압이 낮아져서 공기량이 증가되는 현상을 보이는 것으로, 이는 일반적인 건조이론에 반대현상을 나타내고 있다.However, in the conventional hot air dryer, since the air is blown by a constant motor, in the initial stage of drying, the wind pressure is increased by a large volume of the dry matter, and a small amount of air is blown, and the volume of the dry matter as the dry of the dry matter proceeds. The decrease in wind pressure decreases and the air volume increases, which is opposite to the general drying theory.

따라서, 이러한 종래의 열풍건조기는 건조말기에 열풍의 온도 및 풍량을 조질키 어렵기 때문에 피 건조물의 갈변현상을 유발시켜서 빈 건조에는 부적합할 뿐만 아니라, 건조에 소용되는 열원에너지의 과다 소비로 지출경비를 가중시키는 결점이 있었던 것이다.Therefore, such a conventional hot air dryer is difficult to control the temperature and air volume of the hot air at the end of drying, which causes browning of the product to be dried and is not suitable for empty drying, but also due to excessive consumption of heat source energy used for drying. There was a flaw that aggravated.

본 고안은 상기와 같은 종래의 걸점들을 해결 보완하여 피건조물의 건조 특성과 건조 기간에 따라서 열풍의 온도 및 풍량을 적절히 조절하여 공급 하므로서 피건조물의 갈변 현상을 방지할수 있을 뿐만 아니라 열원 에너지의 과다 소비를 방지하고 열 효율을 최대한 증대시킬수 있는 열풍건조기를 제공하고져 함에 고안의 목적이 있는 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves and complements the above-mentioned conventional bases, and accordingly supplies and regulates the temperature and air volume of the hot air according to the drying characteristics and drying period of the dried product to prevent browning of the dried product as well as excessive consumption of heat source energy. The purpose of the present invention is to provide a hot air dryer that can prevent and increase the thermal efficiency as much as possible.
