Description

농수산물 건조기{Dryer For Agricultural and Marine Product}{Dryer For Agricultural and Marine Product}

본 발명은 농수산물 건조기에 관한 것으로, 보다 상세하게는 피건조물을 열풍 뿐만 아니라 원적외선으로 건조시켜 건조효율을 높이고, 에너지를 절약할 수 있는 농수산물 건조기에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a dryer for agricultural and marine products, and more particularly, to a dryer for agricultural and marine products, which is capable of drying and drying energy by far infrared rays as well as hot air.

통상 농수산물(고추, 감, 버섯, 무, 멸치, 오징어, 김, 미역, 다시마 등)을 건조하기 위해서는 야외에 별도의 건조장을 만들어 햇볕과 바람에 의해 자연건조시키는 경우가 많다. In order to dry agricultural and horticultural products (red pepper, persimmon, mushroom, radish, anchovy, squid, seaweed, seaweed, kelp, etc.), a separate drying area is made outdoors and natural drying is carried out by sunlight and wind.

자연건조의 경우에는 건조 기간 동안의 일조량, 온도, 습도 등을 인위적으로 조절할 수 없어 건조효율이 낮고 농수산물이 부패되기도 하며 또한 파리, 개미 등 해충에 의해 농수산물의 위생을 보장할 수 없는 문제점이 있다. In case of natural drying, it is not possible to artificially control the amount of sunshine, temperature and humidity during the drying period, so that the drying efficiency is low and the agricultural and marine products are spoiled, and hygiene of agricultural and marine products can not be guaranteed due to pests such as flies and ants.

이와 같은 자연건조의 단점을 보완하기 위해 농수산물을 건조할 수 있는 농수산물 건조기가 개발되어 사용되고 있다. 최근의 농수산물 건조기(100)는 대한민국 공개특허 2010-0042392호에 개시된 바와 같이 개폐 도어(120)를 갖는 본체(110) 내부에 건조실(130)을 형성하고 전기 히터와 송풍기에 의해 생성된 고온의 열풍을 건조실 내의 피건조물에 공급하는 형태가 주를 이루고 있다(도 1 참조). 등유와 같은 연료를 연소시켜 열원으로 사용되기도 하였지만, 최근에는 전기를 이용하는 경우가 대부분이다.In order to overcome the disadvantages of such natural drying, agricultural and marine product driers capable of drying agricultural and marine products have been developed and used. The recent agricultural and horticultural product dryer 100 has a drying chamber 130 formed inside a main body 110 having an opening and closing door 120 as disclosed in Korean Patent Publication No. 2010-0042392 and a high temperature hot wind generated by an electric heater and a blower (See Fig. 1). It has been used as a heat source by burning fuel such as kerosene, but in recent years, electricity is mostly used.

전기를 이용하는 농수산물 건조기의 경우에도 일반적인 전기저항 히터를 사용하는 경우(대한민국 공개특허 2010-0042392호)가 대부분이지만, 면상발열체를 사용하거나(대한민국 공개특허 2007-0037297호), 원적외선 램프를 사용하기도 한다 (대한민국 공개특허 2014-0111803호). 면상발열체 및 원적외선 램프의 경우 열원의 강도가 낮고 열전달이 효율적으로 이루어지지 못하여 건조효율이 낮은 문제점이 있다. In the case of a dryer for agricultural and marine products using electric power, most of them use a general electric resistance heater (Korea Patent Publication No. 2010-0042392), but they use a surface heating element (Korean Patent Publication No. 2007-0037297) or a far-infrared lamp (Korea Patent Publication No. 2014-0111803). In the case of the surface heating element and the far infrared ray lamp, the strength of the heat source is low and the heat transfer is not efficiently performed.

일반적으로 많이 사용되는 전기저항 히터를 열원으로 사용하는 농수산물 건조기의 작동은 다음과 같이 이루어진다. (도 2 참조)The operation of the agricultural and marine product dryer, which uses a generally used electric resistance heater as a heat source, is as follows. (See Fig. 2)

건조실 내부에는 피건조물(10)을 담은 채반(140)이 복수 개 설치되며, 건조실(130) 상방에 모터(150)와 팬(160)이 설치되어 건조실(130) 내부의 공기를 건조실 상측으로 흡입한다. 흡인된 공기는 히터(170)에 의해 가열된 후 건조실(130) 측방의 격실(180)을 통해 공급된 후, 건조실 측벽 통공(190)을 통해 건조실(130)로 공급된다. A plurality of trays 140 containing the object 10 to be dried are installed inside the drying chamber and a motor 150 and a fan 160 are installed above the drying chamber 130 to suck air in the drying chamber 130 upward do. The sucked air is heated by the heater 170 and then supplied through the compartment 180 on the side of the drying chamber 130 and then supplied to the drying chamber 130 through the drying chamber side wall aperture 190.

건조실(130) 상측 외부에는 개폐가능한 급기구(200)가 설치되며 건조실(130)후벽에는 건조실 외부와 연통된 배기구(210)가 설치되어 있다. 급기구(200)를 닫은 채 건조시키는 것을 순환 건조 방식이라 하고, 급기구(200)를 열어 외부 공기를 건조실(130) 내로 유입시키며 건조실(130) 내의 일부 공기를 배기구(210)로 배출하는 배기 건조 방식이 교대로 사용된다. 순환 건조 방식은 건조실 내부의 온도를 상승시키는 단계에서 사용되며, 배기 건조 방식은 피건조물로부터 증발한 습기를 배출시키는 단계에서 사용된다. An openable and closable air supply device 200 is installed on the upper side of the drying chamber 130 and an air outlet 210 communicating with the outside of the drying chamber 130 is installed on the rear wall of the drying chamber 130. The air supply mechanism 200 is opened and the air supply mechanism 200 is closed while the air supply mechanism 200 is opened to allow the outside air to flow into the drying chamber 130 and the air in the drying chamber 130 to the air discharge port 210 Drying alternatives are used. The circulation drying method is used in the step of raising the temperature inside the drying chamber, and the exhaust drying method is used in the step of discharging moisture evaporated from the drying object.

이와 같은 종래의 농수산물 건조기는 히터(170)가 건조실(130) 측방의 격실(180) 입구쪽에 설치되어 있어, 열풍이 하부로 전달되게 되어 있고, 격실(180) 벽에 열이 전달됨으로써 아래로 갈수록 열풍의 온도가 감소하여 전체적으로 에너지 효율이 떨어짐과 함께 건조 온도가 균일하지 않게 되는 문제점이 있다. In such a conventional agricultural and marine products dryer, the heater 170 is installed at the inlet side of the compartment 180 on the side of the drying chamber 130, and hot air is transmitted to the lower portion. As heat is transferred to the compartment 180 wall, There is a problem that the temperature of the hot air decreases and the energy efficiency as a whole deteriorates and the drying temperature becomes uneven.

또한 건조실 상측으로 열풍이 빠져 나가므로, 상단 채반에 거치된 피건조물은 하단 채반에 거치된 피건조물에서 배출된 습기와 접촉하게 되어 건조효율이 낮아지게 된다. In addition, since the hot air escapes to the upper side of the drying chamber, the drying substance placed on the upper side contact with the moisture released from the drying substance placed on the lower side, lowering the drying efficiency.

한편, 배기건조 방식으로 건조하는 단계에서는 외부공기가 유입되는 만큼 내부의 열풍이 고스란히 외부로 배출되어 에너지가 낭비되는 문제점도 있다. On the other hand, in the step of drying by the exhaust drying method, there is also a problem that the external hot air is discharged to the outside as much as the outside air is introduced, wasting energy.

히터(170)를 거쳐 배출되는 열풍은 히터(170) 앞에 설치된 블레이드부(250)에 의해 건조실 내부로 넓게 확산되게 된다. 블레이드부(250)는 도 10에 도시된 바와 같이 블레이드(255)에 의해 히터를 통해 나오는 열풍의 송풍 방향을 변경시키게 된다. 본 발명의 농수산물 건조기는 종래의 농수산물 건조기와 달리 열풍이 건조실(130) 내부의 히터(170)에 의해 생성되므로 격실 등을 통과하며 발생하는 열손실이 없어 에너지를 절약할 수 있다. 또한 발열 송풍부(240)가 건조실 후방으로 함몰된 반사갓 형태를 이루고 있기 때문에 히터 가열시 생성되는 원적외선 역시 건조실 내부로 넓게 확산되게 되며, 원적외선이 건조실 벽 등에 흡수되어 손실되지 않고 피건조물에 조사되게 된다. 원적외선은 피건조물의 표면 아래 부분으로 침투하여 피건조물을 가열하게 되므로, 표면만을 열풍에 의해 건조하는 종래의 건조기보다 낮은 온도에서 건조가 가능하여 건조 효율이 높고, 피건조물 역시 표면만 높은 온도로 과도하게 건조되는 일 없이 표면과 내부의 건조도에 차이가 적게 되므로건조품질이 우수하게 된다. The hot air discharged through the heater 170 is widely diffused into the drying chamber by the blade 250 installed in front of the heater 170. The blade unit 250 changes the blowing direction of the hot air flowing through the heater by the blade 255 as shown in FIG. Since the hot air is generated by the heater 170 inside the drying chamber 130 unlike the conventional agricultural and aquatic product drier of the present invention, energy can be saved because there is no heat loss generated through the compartment and the like. In addition, since the heat releasing part 240 is formed as a reflection gutter which is recessed toward the back of the drying room, the far-infrared rays generated when the heater is heated are also diffused widely into the drying chamber, and far infrared rays are absorbed into the drying room . Since the far infrared rays penetrate into the lower part of the surface of the object to be dried, the object to be dried is heated, so that the drying efficiency can be higher than that of the conventional dryer in which only the surface is dried by hot air, So that the difference in the degree of drying between the surface and the inside is reduced, and thus the drying quality is excellent.

또한 히터(170)가 피건조물 가까이에 설치되므로 건조시간이 단축되며, 이에 따른 에너지의 절약이 가능하다. 또한 발열 송풍부(240)가 다층으로 배치되어 피건조물을 건조시킨 후, 채반이 설치된 건조실(130) 측벽의 통공(190)으로 피건조물의 수분을 함유한 공기가 빠져나가기 때문에 건조실(130) 상단 채반에 거치된 피건조물이 눅눅해지지 않게 되며, 건조실 상단으로부터 하단까지 각 배치된 발열 송풍부의 히터를 각각 제어하여 균일한 건조 조건을 형성하거나, 피건조물에 따라 서로 다른 건조조건도 형성할 수 있어, 피건조물의 건조품질을 향상시킬 수 있다.(도 4,6 참조) In addition, since the heater 170 is installed near the object to be dried, the drying time is shortened and energy can be saved accordingly. Since the air containing the moisture of the drying object escapes through the through hole 190 in the side wall of the drying chamber 130 in which the tray is installed after the drying of the drying object by arranging the heating airflow portions 240 in multiple layers, It is possible to form uniform drying conditions by controlling the heaters of the heating and blowing units arranged from the upper end to the lower end of the drying chamber respectively or to form different drying conditions depending on the objects to be dried , Drying quality of the object to be dried can be improved (see Figs. 4 and 6)

히터를 각각 제어하기 위해서는 건조실 상단에서 하단 사이의 정해진 위치에 온도 센서(도시하지 않음.)를 복수 개 설치하는 것도 가능할 것이다. In order to control each of the heaters, it is also possible to provide a plurality of temperature sensors (not shown) at predetermined positions between the upper end and the lower end of the drying chamber.

건조실(130) 내에 공급된 열풍은 피건조물을 건조시킨 후, 건조실(130) 측벽의 통공(190)을 통해 격실(180)로 공급된 후, 덕트(260)를 거쳐 팬(160)으로 이동하게 된다. (도 7,8 참조)The hot air supplied into the drying chamber 130 is dried and then supplied to the compartment 180 through the through hole 190 in the side wall of the drying chamber 130 and then moved to the fan 160 through the duct 260 do. (See Figs. 7 and 8)

본체(110) 상측에 구비되는 덕트(260)의 일측 단부에 격실(180)이 연결되어 건조실 내의 공기를 흡입하게 되며, 덕트(260)의 다른 측 단부에는 열교환기(300)가 설치된다. 열교환기(300)는 도 11과 같이 서로 직교하는 제 1,2 통로(310,320)를 구비한 것이다. A compartment 180 is connected to one end of the duct 260 provided on the main body 110 to suck air in the drying chamber and a heat exchanger 300 is installed on the other side of the duct 260. The heat exchanger 300 includes first and second passages 310 and 320 which are perpendicular to each other as shown in FIG.

열교환기(300)의 제 1 통로(310)는 제 1 입구부(311)를 통해 덕트 내의 공기가 유입되어 제 1 출구부(312)를 통해 농수산물 건조기 외부로 배출하도록 이루어져 있으며, 열교환기의 제 2 통로(320)는 제 2 출구부(322)가 팬(160)에 연결되어 팬(160)의 작동에 따라 제 2 입구부(321)를 통해 덕트(260) 내의 공기가 유입되도록 이루어져 있다.(도 8 참조) The first passage 310 of the heat exchanger 300 is configured such that air in the duct flows through the first inlet 311 and is discharged to the outside of the agricultural and seawater dryer through the first outlet 312, The second outlet 322 of the second passage 320 is connected to the fan 160 so that the air in the duct 260 flows through the second inlet 321 according to the operation of the fan 160. (See Fig. 8)

또한, 열교환기(300) 상류지점의 덕트(260)에는 개폐가능한 급기구(200)가 설치되어 있다. The duct 260 at a point upstream of the heat exchanger 300 is provided with a feed mechanism 200 that can be opened and closed.

급기구(200)를 닫으면 덕트(260) 내의 공기는 모두 제 2 입구부(321)로 유입되어 제 2 출구부(322)를 통해 팬(160)에 공급되는 순환 건조방식으로 건조가 이루어진다(도 8의 화살표 ①). When the air supply mechanism 200 is closed, the air in the duct 260 flows into the second inlet portion 321 and is then supplied to the fan 160 through the second outlet portion 322 to be dried 8 arrow ①).

급기구(200)가 열려있을 경우에는 덕트(260) 내를 흐르는 공기와의 압력 차에 의해 급기구(200)를 통해 덕트(260) 내로 외부 공기가 유입되게 된다. When the air supply mechanism 200 is open, external air flows into the duct 260 through the air supply mechanism 200 due to a pressure difference between the air flowing through the duct 260 and the air supply mechanism 200.

덕트(260) 내의 공기 중 일부는 제 2 입구부(321)로 유입되어 제 2 출구부(322)를 통해 팬(160)에 공급되며(도 8의 화살표 ①), 덕트(260) 내의 공기 중 급기구(200)로 유입된 공기의 양만큼 제 1 입구부(311)를 통해 제 1 통로(310)로 유입된 후 제 1 출구부(312)를 통해 건조기 외부로 배출되게 되는(도 8의 화살표 ②) 배기 건조 방식으로 건조가 진행되게 된다. A part of the air in the duct 260 flows into the second inlet portion 321 and is supplied to the fan 160 through the second outlet portion 322 The air is introduced into the first passage 310 through the first inlet 311 and discharged to the outside of the dryer through the first outlet 312 by the amount of air introduced into the air supply mechanism 200 Arrow ②) Drying will proceed by exhaust drying method.

배기 건조 방식에서 제 1 통로(310)를 통해 외부로 배출되는 열풍은 제 1 통로(310)에 열을 전달하면서 외부로 배출되게 되고, 이러한 열은 제 1 통로(310)와 서로 직교하며 적층된 제 2 통로(320)에 전달되어 급기구(200)에서 유입되어 제 2 통로(320)를 통과하게 되는 외부 공기의 온도를 올려주는 작용을 하게 되므로 열풍의 온도를 올리기 위한 에너지를 더욱 절약할 수 있게 해준다. In the exhaust drying method, hot air, which is discharged to the outside through the first passage 310, is discharged to the outside while transferring heat to the first passage 310. This heat is orthogonal to the first passage 310, The temperature of the outside air that is transferred to the second passage 320 and flows in the air supply mechanism 200 and passes through the second passage 320 is increased. Therefore, the energy for raising the temperature of the hot air can be further saved I will.

건조실 내의 공기를 흡입하여 팬으로 공급하며 선택적으로 배기가 이루어질 수 있도록 한 상기 덕트 및 열교환기의 연결구조는 당업자라면 종래의 농수산물 건조기에도 적용가능함은 물론일 것이다. The connection structure of the duct and the heat exchanger, in which the air in the drying chamber is sucked and supplied to the fan and selectively discharged, can be applied to a conventional agricultural and marine products dryer.
