Description

열 회수 순환 제습형 건조기{omitted}Heat recovery circulation dehumidifying dryer

본 발명은 식 재료는 물론이고 식약 재료 등을 건조하는 건조기에 관한 것으로써, 좀더 구체적으로는 피 건조물의 건조 시 발생하는 습증기가 포함된 뜨거운 공기로부터 수분을 제거한 상태로 건조실의 내부를 순환시키면서 피 건조물의 건조가 이루어질 수 있도록 하는 열 회수 순환 제습형 건조기에 관한 것이다.The present invention relates to a dryer for drying food materials as well as food ingredients, and more particularly, while circulating the interior of a drying chamber in a state in which water is removed from hot air containing wet steam generated when drying the dried material. The present invention relates to a heat recovery circulation dehumidifying dryer which allows drying of a dry matter.

일반적으로 각종 공산품과 농수산물을 건조하는 방법으로는 열풍건조, 냉풍건조, 동결건조 등으로 대별된다.In general, methods for drying various industrial products and agricultural and marine products are roughly classified into hot air drying, cold air drying, and freeze drying.

그 중에서 열풍건조 방법은 건조실에 적재된 피 건조물에 대하여 소정의 온도를 갖는 열풍을 지속적으로 공급하여 피 건조물에 포함된 수분을 증발시킨 다음 이를 대기로 방출함으로써, 피 건조물을 건조하는 것이다.Among them, the hot air drying method is to dry the dry matter by continuously supplying hot air having a predetermined temperature to the dry matter loaded in the drying chamber to evaporate the moisture contained in the dry matter and then discharging it to the atmosphere.

상기와 같은 열풍건조 방법은 비교적 손쉽게 피 건조물을 건조할 수 있어 농산물이나 수산물의 건조에 널리 사용되고 있다.The hot air drying method as described above can be dried relatively easily, and is widely used for drying agricultural products and aquatic products.

도 1은 종래의 농산물건조기를 나타낸 사시도이고 도 2는 도 1의 종단면도로서, 함체형상으로 이루어진 본체(1)의 일 측에 농산물이 적재되는 선반(3)이 서랍식으로 끼워지는 건조실(2)이 구비되어 있고 상기 건조실과 격벽(4)으로 구획된 반 대편 하부에는 가스버너(5)의 가동에 따라 발생된 열이 공기와 열 교환을 하는 열 교환기(6)가 설치된 가열실(7)이 구비되어 있으며 상기 가열실(7)의 상부에 수평 격벽(8)으로 구획된 부위에는 건조실(2)과 가열실(7)로 공기를 순환시키는 송풍기(9)가 설치되어 있다.1 is a perspective view showing a conventional agricultural product dryer, Figure 2 is a longitudinal cross-sectional view of Figure 1, a drying chamber (2) in which a shelf (3) in which agricultural products are loaded on one side of the main body (1) made of a box shape is fitted in a drawer type And a heating chamber (7) provided with a heat exchanger (6) in which heat generated by the operation of the gas burner (5) is exchanged with air at the lower part opposite to the drying chamber and the partition wall (4). It is provided with a blower (9) for circulating air to the drying chamber (2) and the heating chamber (7) at the portion partitioned by the horizontal partition wall (8) in the upper portion of the heating chamber (7).

그리고 상기 격벽(4)의 상부와 하부에는 건조실(2) 측으로 고온의 공기가 순환되도록 하는 공기순환공(10a)(10b)이 각각 형성되어 있고 열 교환기(6)의 일 측에는 공기와 열 교환하고 난 고온의 배기가스가 배출되는 연통(11)이 연결되어 있다.In addition, air circulation holes 10a and 10b are formed at upper and lower portions of the partition 4 to circulate high temperature air to the drying chamber 2, and heat exchange with air at one side of the heat exchanger 6. The communication 11 through which the hot exhaust gas is discharged is connected.

따라서 건조실(2)의 측 벽에 일정 간격으로 설치된 레일(12)에 고추 등과 같은 농산물이 가지런히 담긴 선반(3)을 차례로 끼운 상태에서 가스버너(5)를 착화시키면 가스버너의 착화에 따라 열 교환기(6)가 고온으로 가열되기 시작한다.Therefore, when the gas burner 5 is ignited in a state in which the shelf 3, which includes agricultural products such as red pepper, is inserted into the rails 12 installed at regular intervals on the side wall of the drying chamber 2, the ignition of the gas burner causes heat. Exchanger 6 begins to heat to high temperature.

이러한 상태에서 수평 격벽(8)에 설치된 송풍기(9)가 구동하여 공기가 화살표방향과 같이 공기순환공(10a)(10b)을 통해 순환하면 열 교환기(6)를 거치면서 복사열에 의해 데워져 하부에 형성된 공기순환공(10a)을 통해 건조실(2)의 내부로 유입되어 농산물을 건조시킨 다음 상부에 형성된 공기순환공(10b)으로 배출되므로 건조실 내의 농산물이 건조된다.In this state, when the blower 9 installed in the horizontal bulkhead 8 is driven and the air circulates through the air circulation holes 10a and 10b in the direction of the arrow, it is warmed by radiant heat while passing through the heat exchanger 6. Into the inside of the drying chamber 2 through the air circulation hole (10a) formed to dry the agricultural products and then discharged to the air circulation hole (10b) formed in the upper agricultural products in the drying chamber is dried.

그러나 이러한 종래의 농산물 건조기는 상온인 외기의 온도를 버너 또는 전열기 등을 이용하여 60℃이상으로 가열하여 피 건조물로부터 수분을 증발시킨 다음 고온의 습증기를 대기 중으로 그냥 방출함에 따라 에너지의 소비가 증대되는 결과를 초래하게 되었고, 이에 따라 피 건조물의 건조에 따른 비용이 많이 드는 문제점이 있었다.However, such a conventional agricultural product dryer uses a burner or an electric heater to heat the temperature of the outside air to 60 ° C. or more to evaporate water from the dried material, and then emits high temperature wet steam into the atmosphere, thereby increasing energy consumption. This resulted in a result, there was a costly problem due to the drying of the dried material.

또한, 식 재료 또는 식약 재료로 사용되는 피 건조물인 경우에는 피 건조물의 성분이 변하거나, 변질되는 치명적인 문제점이 발생되었다.In addition, in the case of a dried material used as a food material or a food material, a fatal problem occurs that the components of the dried material change or become deteriorated.

본 발명은 이와 같은 종래의 문제점을 해결하기 위해 안출한 것으로써, 피 건조물을 건조시키는 뜨거운 공기의 순환 경로 상에 뜨거운 공기의 순환을 위한 흡입 팬 및 습증기 제거수단 그리고 순환 공기의 온도를 상승시키는 시스템을 구성하여 고온의 습증기를 건조기의 외부로 방출시키지 않으면서 피 건조물의 건조가 이루어질 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve such a conventional problem, the suction fan and the wet steam removal means for the circulation of hot air on the circulation path of the hot air to dry the dry matter and the system for raising the temperature of the circulating air The purpose is to allow the drying of the dried object without releasing high temperature wet steam to the outside of the dryer.

상기 목적을 달성하기 위한 본 발명의 형태에 따르면, 습증기의 순환 경로상에 증발기, 압축기, 냉각기, 팽창밸브로 이루어진 냉각시스템을 설치하여 냉매파이프로 냉매가 순환되도록 하고 상기 증발기의 후단에는 순환 경로를 구획하는 격벽을 설치함과 동시에 격벽의 중심에는 건조실의 내부 공기를 강제로 흡입하는 흡입 팬을 설치하며 냉각기의 후단에는 공기를 재차 가열하는 가열기를 더 구비하여 뜨거운 공기에 포함된 습증기가 증발기를 통과하면서 제거됨에 따라 온도가 떨어지면 떨어진 온도를 흡입 팬의 모터 및 압축기를 식히는 과정에서 1차적으로 상승시킨 다음 냉각기를 통과하는 과정에서 2차적으로 상승시킨 후 가열기를 통과하면서 3차적으로 가열하는 것을 특징으로 하는 열 회수 순환 제습형 건조기가 제공된다.According to an aspect of the present invention for achieving the above object, by installing a cooling system consisting of an evaporator, a compressor, a cooler, an expansion valve on the circulation path of the wet steam to allow the refrigerant to circulate in the refrigerant pipe and a circulation path at the rear end of the evaporator. At the same time as the partition wall, the suction fan is installed at the center of the partition to forcibly suck the internal air of the drying chamber, and at the rear of the cooler, a heater is further heated to reheat the air, and the wet steam contained in the hot air passes through the evaporator. When the temperature drops as it is removed while the temperature is dropped, the temperature is first increased in the process of cooling the motor and the compressor of the suction fan, and then elevated in the process of passing through the cooler, and then heated in a third manner while passing through the heater. There is provided a heat recovery circulation dehumidifying dryer.

본 발명은 건조실에서 발생된 습증기를 흡입 팬의 구동에 따라 순환 경로 상으로 빨아들여 열 교환이 이루어지는 동안 습증기에 포함된 수분을 제거한 다음 떨어진 온도를 흡입 팬의 모터 및 압축기 그리고 냉각기를 차례로 지나면서 상승시킨 후 가열기에 의해 재 가열하여 건조실 측으로 유입되도록 함으로써, 열 손실에 따른 비용낭비를 미연에 방지하게 되는 효과를 얻게 된다.The present invention sucks the wet steam generated in the drying chamber on the circulation path in accordance with the operation of the suction fan to remove the moisture contained in the wet steam during heat exchange, and then the temperature is raised while passing through the motor, compressor and cooler of the suction fan. After reheating by the heater to be introduced into the drying chamber side, the cost of the heat loss can be prevented in advance.

또한, 식 재료 또는 식약 재료로 사용되는 피 건조물인 경우에도 건조실의 내부로 유입되는 더운 공기의 온도를 인체의 온도와 같은 38℃ 정도로 유지하게 되므로 피 건조물의 성분이 변하거나, 변질되는 현상도 미연에 방지하게 된다.In addition, even in the case of a dried material used as a food material or a pharmaceutical material, the temperature of the hot air flowing into the drying chamber is maintained at about 38 ° C, which is the same as that of the human body. Will be prevented.

이하, 본 발명을 일 실시예로 도시한 도 3을 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, described in more detail with reference to Figure 3 showing the present invention as an embodiment.

도 3은 본 발명의 구성을 나타낸 개략도로써, 본 발명은 습증기의 순환 경로(21) 상에 증발기(22), 압축기(23), 냉각기(24), 팽창밸브(25)로 이루어진 냉각시스템이 설치되어 폐 회로를 구성하는 냉매파이프(26)로 냉매가 순환되도록 되어 있고 상기 증발기(22)의 후단에는 순환 경로(21)를 구획하는 격벽(27)이 설치되어 있으며 상기 격벽(27)의 중심에는 건조실의 내부 공기를 강제로 흡입하는 흡입 팬(28)이 설치되어 있다.3 is a schematic view showing the configuration of the present invention, the present invention is installed on the circulation path 21 of the wet steam, the cooling system consisting of the evaporator 22, compressor 23, cooler 24, expansion valve 25 is installed The refrigerant is circulated to the refrigerant pipe 26 constituting the closed circuit, and a barrier rib 27 is formed at the rear end of the evaporator 22 to partition the circulation path 21. In the center of the barrier rib 27 A suction fan 28 for forcibly sucking the internal air of the drying chamber is provided.

그리고 상기 냉각기(24)의 후단에는 공기를 재차 가열하는 가열기(29)가 설치되어 있다.At the rear end of the cooler 24, a heater 29 for heating air again is provided.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

먼저, 건조실(도시는 생략함)의 내부에 건조할 피 건조물을 넣은 다음 버너를 점화시키면 버너의 착화에 따라 열 교환기가 고온으로 가열되므로 가열된 뜨거운 공기를 건조실의 내부로 공급하여 피 건조물을 건조시키게 되는데, 이러한 상태에서 순환 경로(21) 상에 설치된 흡입 팬(28)이 구동하면 건조실에서 피 건조물의 건조에 따라 발생된 습증기를 포함하고 있던 뜨거운 공기(30)는 순환 경로(21) 측으로 유입되어 차가운 증발기(22)를 통과하면서 온도가 떨어지게 된다.First, put the dry material to be dried in the drying chamber (not shown) and then ignite the burner, so that the heat exchanger is heated to a high temperature according to the ignition of the burner, thereby supplying heated hot air into the drying chamber to dry the dry object. In this state, when the suction fan 28 installed on the circulation path 21 is driven, the hot air 30 containing the wet steam generated by the drying of the object to be dried in the drying chamber flows into the circulation path 21 side. The temperature is lowered while passing through the cold evaporator 22.

이와 같이 습증기를 포함하고 있던 뜨거운 공기(30)가 증발기(22)를 통과하면서 온도가 떨어지면 뜨거운 공기(30)에 포함되어 있던 습증기로부터 제습이 이루어지므로 응축수가 발생되는데, 이렇게 발생된 응축수는 자중에 의해 하방으로 떨어져 응축수받이(31)에 고이게 되므로 고인 응축수가 배출구(31a)를 통해 외부로 드레인(drain)된다.When the temperature of the hot air 30 containing the wet steam passes through the evaporator 22 and the temperature drops as described above, dehumidification is performed from the wet steam included in the hot air 30, so that condensed water is generated. Because it falls down and accumulates in the condensate receiver 31, the accumulated condensate is drained out through the outlet 31a.

상기한 바와 같은 동작으로 인해 뜨거운 공기(30)에 포함되어 있던 수분이 제거되어 건조해진 공기는 차가운 증발기(22)를 통과함에 따라 온도가 떨어지지만, 계속되는 흡입 팬(28)의 구동으로 순환 경로(21)를 이동하는 과정에서 과열된 흡입 팬(28)의 모터(28a) 및 압축기(23)를 냉각시키는 역할을 하면서 온도가 1차적으로 상승된 다음 냉각기(24)를 지나면서 2차적으로 상승하므로 뜨거운 공기(30)의 약 80％정도까지 온도가 상승된다.The air dried by removing moisture contained in the hot air 30 due to the operation as described above drops as the air passes through the cold evaporator 22, but continues to be driven by the suction fan 28. In the process of moving 21, the temperature of the primary rises first and then passes through the cooler 24 while acting to cool the motor 28a and the compressor 23 of the overheated suction fan 28, The temperature is raised to about 80% of the hot air 30.

상기한 바와 같이 뜨거운 공기(30)의 약 80％정도까지 상승된 공기를 건조실의 내부로 공급하여도 되지만, 보다 높은 건조효율을 얻을 수 있도록 냉각기(24)의 후단에 설치된 가열기(29)에 전원을 인가하여 발열되는 가열기(29)를 통과하는 과정에서 가열된 공기(32)의 온도가 뜨거운 공기(30)의 온도와 거의 유사한 38℃까지 도달하도록 상승시킨 다음 이를 건조실의 내부로 공급하여 피 건조물을 건조시키는 과정을 반복적으로 수행하는 것이 보다 바람직하다.As described above, the air raised to about 80% of the hot air 30 may be supplied to the interior of the drying chamber, but the power is supplied to the heater 29 provided at the rear end of the cooler 24 so as to obtain higher drying efficiency. In the process of passing through the heater 29 to generate heat by raising the temperature of the heated air 32 to reach a temperature of 38 ℃ almost similar to the temperature of the hot air 30, it is supplied to the interior of the drying chamber to be dried It is more preferable to repeat the process of drying.

이러한 뜨거운 공기(30)의 이동은 전술한 바와 같이 계속적으로 폐 회로를 이루면서 진행되므로 습증기의 배출로 인한 열 손실을 방지하게 됨은 물론이고 피 건조물의 건조에 따른 시간을 대폭 줄일 수 있게 되는 것이다.As the hot air 30 moves continuously as described above, the hot air 30 is prevented from losing heat due to the discharge of wet steam, and of course, it is possible to drastically reduce the time of drying the dried object.

본 발명의 기술사상은 상기한 바람직한 실시예에 따라 구체적으로 기술되었으나, 전술한 실시예들은 그 설명을 위한 것이며, 그 제한을 위한 것이 아님을 주의하여야 한다.Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiments are for the purpose of description and not of limitation.

또한, 본 발명의 기술분야에서 통상의 전문가라면 본 발명의 기술사상의 범위 내에서 다양하게 변화하여 실시할 수 있음은 이해 가능한 것이다.In addition, it will be understood by those skilled in the art that various changes can be made within the scope of the technical idea of the present invention.
