농산물 건조기의 폐열회수기{WASTE HEAT RECLAIMER OF FARM PRODUCE DRIER}WASTE HEAT RECLAIMER OF FARM PRODUCE DRIER

본 발명은 농산물 건조기에 관한 것으로서, 상세하게는 농산물을 건조할 때 배출구로 버려지는 폐열을 회수하여 외부로부터 흡입공기를 예열시켜 공급함으로써 에너지를 절감시켜 건조비용을 최소화하면서 건조효율이 우수하도록 한 농산물 건조기의 폐열회수기에 관한 것이다.The present invention relates to a agricultural product dryer, and more particularly, to recover the waste heat discarded as an outlet when the agricultural product is dried, and to preheat and supply the intake air from the outside to reduce the energy by minimizing the drying cost and to provide excellent drying efficiency. It relates to a waste heat recovery machine of the dryer.

일반적으로 농산물 건조기는 피 건조물이 담겨진 채반을 적층하여 수용하는 건조실과 연결된 일측 가열실 내에 열교환기를 갖는 버너와 송풍기를 설치하여 공기흡입구로 유입된 외부의 찬 공기를 가열하여 건조실을 통과하면서 농산물을 건조시켜 주도록 하고 건조실을 통과한 폐열은 배기관을 통해 외부로 배출되도록 구성된다.In general, agricultural product dryers dry produce by passing burners and blowers having a heat exchanger in a heating chamber connected to a drying chamber for stacking a tray containing dry matter and heating the cold air introduced into the air inlet to pass through the drying chamber. Waste heat passing through the drying chamber is discharged to the outside through the exhaust pipe.

그러나 습도가 높은 외부의 찬 공기를 흡입하여 가열할 경우 결로현상으로 발생된 수분이 부품을 부식시키고 또 가열공기는 습도가 높아 건조효율을 저화시키게 되며, 외부의 찬 공기가 열교환기를 통하여 원하는 온도로 건조실을 가열시켜 주는데에 상당한 시간과 불필요한 연료가 과다 소요되므로 열효율이 떨어지게 된다.However, in case of heating by inhaling cold outside air with high humidity, moisture generated by condensation corrodes parts, and heating air has high humidity, which reduces the drying efficiency. Heating the drying chamber takes a considerable amount of time and unnecessary fuel, resulting in poor thermal efficiency.

이에 상기한 문제점을 보완하기 위하여 찬 공기를 흡입하는 건조기의 공기흡입구 내에 건조실의 배기관을 통하여 배출되는 폐열을 이용한 라지에이터나 히터파이프 등을 설치하여 외부의 찬 공기가 1차 가열된 후 가열실 내부로 유입되어 열교환기에 의한 2차 가열이 이루어지도록 하여 건조효율과 열효율을 높여주도록 하고 있으나 이들은 건조기 제작시에 내부에 일체로 형성해주어야 하므로 제작하기가 상당히 까다로우면서 부품이 비싸 제품의 제작비용이 상승하게 되므로 가격경쟁력이 저화되고 또한 가열된 공기의 배출이 원활하지 않아 습도가 높아 건조효율이 여전히 떨어지게 되는 등의 문제점을 가지고 있는 것이었다.In order to solve the above problems, a radiator or a heater pipe using waste heat discharged through the exhaust pipe of the drying chamber is installed in the air inlet of the dryer that sucks the cold air, and the external cold air is first heated, and then into the heating chamber. Secondary heating by heat exchanger is introduced to increase the drying efficiency and thermal efficiency, but these are required to be integrally formed when manufacturing the dryer, which makes it very difficult to manufacture and increases the manufacturing cost of the product. Therefore, the price competitiveness is lowered, and the discharge of the heated air is not smooth, and the humidity is high, so that the drying efficiency is still deteriorated.
