Is formed to form a drying chamber in which a drying rack is installed, and a hot air transport path in which a plurality of air circulation fans are installed is partitioned by a partition wall in which a heater is installed on the upper left side of the drying chamber and a plurality of air vents are formed on the lower side of the drying chamber. By the inner and outer reverse partition partition is formed a closed circulation hot air transport path circulating waste hot air, forming a refrigerator and a temperature compensation heating coil formed with a water discharge pipe in the upper center of the drying chamber, the present invention Air circulating agricultural and marine product drying device using a freezer of air circulates hot air heated by a heater The fan is forcedly blown to the agricultural and marine products loaded in the drying chamber to dry the agricultural and marine products, and the waste hot air discharged through the drying chamber to the wet state is removed by the freezer and is heated to the heater side with the preheated air preheated by the heating coil. By circulating, the air inside the drying apparatus is circulated inside without discharging to the outside to shorten the drying time of the agricultural and marine products to obtain dry agricultural products having excellent drying conditions, and the waste warm air passing through the agricultural and marine products to the outside of the drying apparatus. By removing only moisture and recirculating and supplying it in the preheated state, it minimizes the internal heat loss of the drying device and reduces the power and fuel consumption by operating the heater. It is to be minimized.

일반적인 농수산물건조기는 건조실 내부에 설치된 다단의 받침레일에 피건조물이 담겨진 채반을 재치시키고 일측의 열풍 공급부에서 열풍을 건조실로 공급하여 건조한 다음 폐열의 일부는 열풍공급부로 보내지고 나머지는 배풍구를 통해 외부로 빠져나가게 된다.In general, the agricultural and marine product dryers place a table containing dried goods on a multi-stage supporting rail installed inside the drying chamber, supply hot air to the drying room from one side of the hot wind supply unit, and dry some of the waste heat to the hot air supply unit, and the rest is sent to the outside through the vent. To get out.

즉, 상기 농산물건조기의 열풍공급부는 경유를 연료로 하는 버너 또는 전기히터 방식의 에너지원을 사용하여 외부에서 유입되는 공기를 가열하여 열풍을 발생시키게 되므로 열풍공급부로 유입되는 외부공기의 온도에 따라 소정온도의 열풍을 발생시키기 위한 에너지 소비량이 달라지게 된다.That is, the hot air supply unit of the agricultural product dryer generates hot air by heating the air introduced from the outside using a burner or an electric heater type energy source using diesel fuel as a predetermined temperature according to the temperature of the external air introduced into the hot air supply unit. Energy consumption for generating hot air of temperature will be different.

그러나 종래에는 건조실 내의 농수산물을 열풍에 의해 건조한 다음 폐열의 일부는 외부공기와 함께 열풍공급부로 보내지고 나머지는 배풍구를 통해 배출되기 때문에 에너지낭비가 많고 대기온도의 외부공기가 열풍공급부로 보내져서 열풍을 발생시키기 위해서는 많은 에너지를 필요로 하기 때문에 그만큼 농수산물 건조비용이 많이 들게 되어 농수산물의 경쟁력이 떨어지게 되는 결점이 있었다.However, conventionally, the agricultural and marine products in the drying room are dried by hot air, and then a part of the waste heat is sent to the hot air supply unit along with the external air and the remaining air is discharged through the vents, which causes a lot of energy waste and external air at atmospheric temperature is sent to the hot air supply unit. Since it requires a lot of energy in order to generate a large amount of agricultural and fishery drying costs, the competitiveness of agricultural and marine products was reduced.

또, 배풍구측의 역풍에 의한 온풍정체현상으로 열풍의 공급이 순조롭지 못하고 계속하여 전조실에 머무르게 되어 습한 성분을 함유한 역풍에 의해 농수산물에 가해지는 열풍의 수분제거율이 낮으며, 건조시간이 오래 걸리는 결점이 있으며, 외부공기를 계속하여 흡입하여 가동을 하게 되므로, 비가 많이 내리는 우기시에는 습한 외부공기가 유입됨으로 농수산물의 건조 효율이 저하되는 결점이 있었다.In addition, the hot wind stagnation caused by the reverse wind on the side of the vent hole keeps the supply of the hot air continuously and stays in the chamber, so the moisture removal rate of the hot air applied to the agricultural and aquatic products by the back wind containing the wet ingredients is low, and the drying time is long. There is a drawback that takes a long time, because the outside air is continuously inhaled and operated, during the rainy season when there is a lot of rain, there is a drawback that the drying efficiency of agricultural and marine products is reduced by the inflow of wet outside air.

또한, 종래의 대부분의 건조기는 경유를 사용하는 구조로 되어 있어 비싼 경 유를 사용한 만큼의 농수산물의 건조효과를 거둘 수 없으며, 특히 경유의 연소시에 발생하는 매연에 의해 대기가 오염되는 등의 건조기를 사용하는 대부분의 농어촌 청정지역에 환경오염을 일으키게 되는 결점이 있었다.In addition, most conventional dryers have a structure using diesel oil, and thus, the drying effect of agricultural and aquatic products as much as expensive diesel oil cannot be achieved, and the air is contaminated by the smoke generated during combustion of diesel oil. Most farming and fishing villages that use them have the disadvantage of causing environmental pollution.

따라서, 본 발명은 상기와 같은 종래의 결점을 적게 하고자 한 것으로, 히터에 의해 데워진 열풍을 공기순환팬에 의해 건조실에 적재된 농수산물측으로 강제송풍시켜 농수산물을 건조시킴과 동시에 건조실을 통과하여 습한 상태로 배출되는 폐온풍이 냉동기에 의해 수분이 제거되고 히팅코일에 의해 예열된 예열풍의 상태로 히터측으로 순환되도록 함으로써, 건조장치의 내부에 있는 공기를 외부로 배출하지 않고 내부에서 순환시켜 농수산물의 건조시간을 단축시켜 건조상태가 우수한 건조농수산물을 얻을 수 있으며, 농수산물을 지나온 폐온풍을 상기 건조장치의 외부로 배출하지 않고 수분만을 제거하여 예열된 상태로 재순환시켜 사용함으로써 건조장치의 내부 열손실을 최소화시키고, 히터를 가동함에 따라 전력 및 연료소모를 줄여 주어 유지비를 절감시킬 수 있는 냉동기를 이용한 내부공기순환식 농수산물건조장치를 제공함에 목적이 있다.Therefore, the present invention is intended to reduce the conventional drawbacks as described above, by forcibly blowing hot air warmed by the heater to the agricultural and marine products loaded in the drying chamber by the air circulation fan to dry the agricultural and marine products at the same time through the drying chamber in a humid state The waste hot air discharged is circulated to the heater side in the state of the preheating air preheated by the heating coil by removing the moisture from the freezer, thereby circulating the air inside the drying apparatus without releasing it to the outside to dry the agricultural and marine products. It is possible to obtain a dry aquatic products with excellent drying conditions by shortening, to minimize the internal heat loss of the drying apparatus by recycling the preheated state by removing only the moisture without exhausting the waste warm air passing through the agricultural and aquatic products to the outside of the drying apparatus Maintenance costs by reducing power and fuel consumption The purpose is to provide an internal air circulation agricultural and marine products drying apparatus using a freezer that can reduce the.

한편, 상기 건조실(10)의 상부 중앙으로는 물배출관(31)이 연결 형성된 냉동기(30)가 설치되어 상기 건조실(10)을 통과하면서 농수산물을 건조시키고 배출되는 폐온풍에 포함된 수분이 상기 냉동기(30)의 차가운 표면을 지나면서 수분이 빼앗기고 건조한 상태의 중,저온의 공기가 되어 이송되고, 상기 냉동기(30)에서 제거된 수분은 물배출관(31)을 통하여 건조장치(1)의 외부로 배출된다.On the other hand, in the upper center of the drying chamber 10 is provided with a freezer (30) is connected to the water discharge pipe 31 is dried in the agricultural product while passing through the drying chamber 10, the moisture contained in the waste hot air discharged to the freezer Moisture is taken away while passing through the cold surface of the (30) and is transferred to the air of low and medium temperature in the dry state, the moisture removed from the freezer (30) to the outside of the drying apparatus (1) through the water discharge pipe (31) Discharged.

또, 상기의 냉동기(30)의 일측으로는 온도보상용 히팅코일(32)이 형성되어 상기 냉동기(30)에서 수분이 제거되고 온도가 낮아진 중, 저온의 건조공기가 상기 히팅코일(32)을 통과하면서 낮아진 온도를 보상받아 예열이 된 예열풍으로 순환이동한다.In addition, a temperature compensation heating coil 32 is formed at one side of the refrigerator 30 so that moisture is removed from the refrigerator 30 and the temperature is lowered, and low temperature dry air is used to cool the heating coil 32. It passes through the preheated preheated wind to compensate for the lowered temperature as it passes.

상기의 히팅코일(32)은 상기의 냉동기(30)를 가동시킬 때 발생하는 폐열을 회수하여 열원으로 사용하게 되어 약 70℃의 높은 온도를 발생하게 되는 것으로, 별도의 히팅코일(32)을 가열하기 위한 에너지가 필요 없게 되어 에너지가 절약된다.The heating coil 32 is to recover the waste heat generated when operating the refrigerator 30 is used as a heat source to generate a high temperature of about 70 ℃, heating the separate heating coil 32 There is no need for energy to save energy.

따라서, 상기와 같이 냉동기(30)에 의해 수분이 제거된 건조공기가 히팅코일(32)을 지나면서 70℃ 정도의 예열된 예열풍 상태로 히터(16)측으로 순환되도록 함으로써, 외부공기가 유입되지 않고 내부공기를 재순환시켜 건조하게 되므로, 건조장치(1)를 가동시키기 위한 동력 및 연료의 소비를 줄일 수 있어 유지비를 절감할 수있으며, 우천시와 같이 건조장치(1)의 외부 날씨의 영향에 전혀 구애됨이 없이 양질의 농수산물 건조가 가능한 것이다.Therefore, the dry air removed by the refrigerator 30 as described above is circulated to the heater 16 in the preheated preheating state of about 70 ° C. while passing through the heating coil 32, thereby preventing external air from entering. Since it is dried by recirculating the internal air without drying, it is possible to reduce the consumption of power and fuel for operating the drying apparatus 1, thereby reducing the maintenance cost, and at the same time as in rainy weather. It is possible to dry high-quality agricultural products without being particular about it.

이상과 같이 본원 발명은 히터에 의해 데워진 열풍을 공기순환팬에 의해 건조실에 적재된 농수산물측으로 강제송풍시켜 농수산물을 건조시킴과 동시에 건조실을 통과하여 습한 상태로 배출되는 폐온풍이 냉동기에 의해 수분이 제거되고 히팅코일에 의해 예열된 예열풍의 상태로 히터측으로 순환되도록 함으로써, 건조장치의 내부에 있는 공기를 외부로 배출하지 않고 내부에서 순환시켜 농수산물의 건조시간을 단축시켜 건조상태가 우수한 건조농수산물을 얻을 수 있으며, 농수산물을 지나온 폐온풍을 상기 건조장치의 외부로 배출하지 않고 수분만을 제거하여 예열된 상태로 재순환시켜 사용함으로써 건조장치의 내부 열손실을 최소화시키고, 히터를 가동함에 따라 전력 및 연료소모를 줄여 주어 유지비를 절감시킬 수 있으며, 우천시와 같은 습한 날씨의 영향에 전혀 구애됨이 없이 양질의 농수산물을 단시간에 건조가 가능하며, 전기를 사용함으로써, 매연의 발생이 없어 건조기를 사용하는 대부분의 농어촌 청정지역의 환경오염을 방지할 수 있는 것이다.As described above, the present invention forcibly blows the hot air heated by the heater to the agricultural and marine products loaded in the drying chamber by the air circulation fan to dry the agricultural and marine products, and at the same time, the waste hot air discharged in the wet state through the drying chamber removes moisture by the freezer. And by circulating to the heater side in the state of preheating air preheated by the heating coil, by circulating the air inside the drying apparatus without discharging to the outside to shorten the drying time of agricultural and marine products to obtain a dry agricultural product with excellent drying conditions It is possible to minimize the internal heat loss of the drying apparatus by using the recycled hot water by removing only the moisture without discharging the waste hot air passing through the agricultural and aquatic products to the outside of the drying apparatus, and reducing the power and fuel consumption by operating the heater. It can reduce the maintenance cost by reducing Without regard to any impact of the dry seeds is possible and the quality of agricultural products in a short period of time, the use of electricity, not the generation of soot is to prevent the pollution of most of the rural areas to clean the dryer.
