Description

농수산물 건조장치{Drying apparatus for agricultural and marine products}Drying apparatus for agricultural and marine products

본 고안은 농수산물 건조장치에 관한 것으로, 더욱 구체적으로는 건조실로 열풍공급을 하는 열교환기의 열풍효율이 높고 건조실은 전체공간에 균등한 열풍공급을 할수 있게 한 구성으로 건조효율이 크게 향상되도록 한 것이다.The present invention relates to an agricultural and aquatic product drying apparatus, and more specifically, the hot air efficiency of the heat exchanger for supplying hot air to the drying chamber is high, and the drying chamber is configured to greatly improve the drying efficiency by providing a uniform hot air supply to the entire space. .

일반적인 농수산물 건조장치에서는 다수의 연통관이 소정간격을 두고 상하좌우에 집합된 형태로 횡설된 열교환기로 구성되어 연소실의 연소열이 연통관을 순차적으로 거치면서 연통관을 가열하도록 되어 있고 그 가열된 연통관 외면에 유입되는 외부공기가 접촉되어 가열되는 열풍을 건조실에 공급되게 하였으나, 종래의 열교환기는 두개의 연통관이 한조가 되어 연소가스를 통과시키기 때문에 연소가스가 빨리대기로 방출되어 그만큼 열이 밖으로 많이 빠져나가게 되어 열효율이 크게 떨어지게 되었을 뿐만 아니라 그 연통관은 중공부로 되어 있어서 연소열이 통과하는 연통관의 중심부분에서는 온도가 높고 가장자리 쪽은 점차적으로 온도가 낮아지기 때문에 연통관 외면에 연소열이 효과적으로 전달되지 못하여 열풍효율이 떨어지게 되었다.In general agricultural and marine product drying apparatus, a plurality of communication tubes are arranged in the form of a heat exchanger arranged in the form of the top, bottom, left and right at a predetermined interval so that the heat of combustion in the combustion chamber passes through the communication tube sequentially to heat the communication tube and flows into the heated communication tube outer surface. The hot air that is heated by contacting the outside air is supplied to the drying chamber. However, the conventional heat exchanger has two communicating pipes in a pair and passes the combustion gas so that the combustion gas is released to the atmosphere quickly and the heat is drawn out much. Not only was it greatly dropped, but the communication tube was hollow, so that the temperature was high at the center portion of the communication tube through which the heat of combustion passes, and the temperature gradually decreased at the edge, so that the heat of combustion was not effectively transmitted to the outer surface of the communication tube, resulting in inferior hot air efficiency.

또한, 건조실은 하나의 수직통로로 부터 수평통로에 가열건조공기를 공급받기 때문에 열풍이 유입되는 입구쪽 건조공간은 열풍압력이 높아서 건조가 빠르게 되고 그 반대편에 위치한 건조공간은 열풍압력이 낮아 건조가 더디게 되는 등 건조실의 전체적인 공간의 압력편차가 심하여 농산물건조가 균등하지 못한 문제점이 있었다.In addition, since the drying chamber receives heating and drying air from the one vertical passage to the horizontal passage, the inlet drying space where hot air flows in has a high hot air pressure, so that drying is quick, and the drying space located on the opposite side has a low hot air pressure. There was a problem that the agricultural product drying is not even because the pressure deviation of the overall space of the drying room is so slow.

본 고안은 이러한 문제점을 해결하기 위하여 열교환기의 가열연소가스가 지나가는 경로를 연통하나하나씩 지나가도록하여 연소열의 체류기간을 길게함과 아울러 열교환기의 연통관내에 꽈배기 형태로 꼬인 와류생성편을 설치하여 연통관을 통과하는 연소열이 와류되도록한 구성으로 연통관 외면에 열전달이 효과적으로 이루어지도록 하며, 건조실은 건조공간에 건조채반을 다단으로 거치시키되 하단부채반에는 하부에서만 열풍공급이 되고 상단부채반에는 하부및 측부에서 각각 열풍을 공급받게 한 구성으로 채반에 공급되는 전체적인 건조공간의 열풍압력편차를 크게 줄일수 있도록 한 농수산물 건조장치이다.In order to solve this problem, the present invention communicates the heating combustion gas of the heat exchanger one by one so as to pass one by one to increase the residence time of the combustion heat and install a vortex forming piece twisted in the form of a pretzel in the communication tube of the heat exchanger. It is designed to make the heat of combustion passing through the communication pipe to vortex effectively to heat transfer to the outside surface of the communication pipe.The drying chamber is equipped with drying trays in multiple stages in the drying space, but the lower fan panel is supplied with hot air only from the lower part and the upper fan panel from the lower and side parts, respectively. It is a agricultural and aquatic product drying device that can greatly reduce the hot air pressure deviation of the overall drying space supplied to the tray by receiving the hot air.

이와같이 된 본 고안의 농수산물 건조장치는 연소실(16)의 연소열이 열교환기(12)에 설치된 다수의 연통관(13)을 순차적으로 거치는 수단으로 연통관(13)을 가열하게 되고 그 가열된 연통관(13)외면의 방열부(15)에는 송풍팬(11)으로 흡입구(10)를 통해 유입되는 외부공기가 접촉되어 가열건조되면서 발생한 열풍을 건조실(20)에 공급하게 된다.In this way, the agricultural and marine products drying apparatus of the present invention heats the communication tube 13 by means of sequentially passing a plurality of communication tubes 13 installed in the heat exchanger 12 by the heat of combustion of the combustion chamber 16 and the heated communication tube 13. The heat radiating part 15 of the outer surface is supplied to the drying chamber 20 with hot air generated while being heated and dried by contacting the external air introduced through the suction port 10 with the blower fan 11.

이때 본 고안의 연통관(13)은 가열연소가스가 지나가는 경로(a-l)를 연통하나하나씩 지나가게 되어 같은 크기의 열교환기에서 연도의 길이가 기존의 것보다 2배정도 길어지게 되므로 그 만큼 연소열의 체류기간이 길어지고 전열면적도 크게하는 효과가 있어 열효율을 높일수 있게 되며, 연통관(13) 내부에 꽈배기 형태로 꼬인 와류생성편(14)이 설치되어 있어서 연통관(13)을 통과하는 연소열이 와류되어 연통관(13)과의 접촉력이 좋아지고 연소열을 골고루 교반하는 작용으로 연통관(13)에 열전달이 잘되므로 연통관(13)외면의 방열부(15)에 접촉되어 열풍을 발생시키는 열교환기의 열풍효율이 크게 높아진다.At this time, the communication tube 13 of the present invention passes through the passage (al) through which the heating combustion gas passes one by one, so that the length of the flue in the heat exchanger of the same size is about twice as long as the existing one, so that the residence period of combustion heat The longer the heat transfer area is also effective to increase the thermal efficiency, the vortex generating piece 14 is twisted in the form of pretzel in the communication tube 13 is installed, the combustion heat passing through the communication tube 13 is vortexed communication tube ( The contact force with 13) is improved and the heat transfer to the communication tube 13 is well carried out by uniformly agitating the combustion heat, so that the hot air efficiency of the heat exchanger that is in contact with the heat radiating part 15 on the outer surface of the communication tube 13 to generate hot air is greatly increased. .

그리고 건조실(20)에 공급되는 열풍은 다단으로 건조채반(30)이 거치된 건조공간에 공급이 이루어지되 하부건조공간의 건조채반(30)은 다공수평판재(21)를 통해 하부로 유입되는 열풍을 공급받게 되고 상부건조공간의 건조채반(30)은 수평통로(22)의 수직통기부(26)와 수평통기부(27)를 통해 열풍을 공급받게 되는바 수직통기부(26)에서는 하부건조공간의 건조채반을 거쳐서된 열풍이 공급되고수평통기부(27)에서는 수직통로(28)에서 열풍이 각긱 공급되기 때문에 전체적인 건조공간의 열풍압력편차를 크게 줄여서 건조공간전체에서 농산물을 균등하게 건조시킬수 있게 된다.In addition, the hot air supplied to the drying chamber 20 is supplied to the drying space in which the drying tray 30 is mounted in multiple stages, but the drying tray 30 of the lower drying space is introduced into the lower portion through the porous horizontal plate 21. The drying tray 30 of the upper drying space is supplied with hot air through the vertical ventilation unit 26 and the horizontal ventilation unit 27 of the horizontal passage 22 and the lower drying unit in the vertical ventilation unit 26. Since hot air is supplied through the drying tray of the space and hot air is supplied from the vertical passage 28 in the horizontal passage part 27, it is possible to dry agricultural products evenly in the entire drying space by greatly reducing the hot air pressure deviation of the entire drying space. Will be.

즉, 상부건조공간은 하부에서 공급되는 열풍이 하부건조공간을 거치면서 점차적으로 낮아지게 되는바 이를 보완하는 수단으로 상부건조공간은 수평통로(22)가 설치되어 수직통기부(26)를 통해서는 하부열풍을 공급하게 되고 수평통기부(27)를 통해서는 관통된 수직통로(28)에서 건조실로 유입되는 열풍이 직접전달되어 공급되므로 상,하부 건조공간에 열풍압력을 균등하게 배분되는 역할이 이루어진다.In other words, the upper drying space is a hot air supplied from the lower is gradually lowered through the lower drying space as a means to compensate for this, the upper drying space is a horizontal passage 22 is installed through the vertical vent 26 The lower hot air is supplied and the hot air flowing into the drying chamber is directly transmitted through the horizontal passage part 27 so that the hot air pressure is evenly distributed to the upper and lower drying spaces. .

이와같이 본 고안의 농수산물 건조장치는 가열연소가스가 지나가는 경로를 연통하나하나씩 지나가도록 한 연통관으로 연소열의 체류기간을 길게하고 열교환기의 연통관내에 꽈배기형태로 꼬인 와류생성편이 설치되어 연통관에 열전달이 잘되게 한 구성으로 열풍효율이 높고, 건조실은 건조공간에 건조채반이 다단으로 거치된 상태에서 하단부채단에는 하부에서만 열풍이 공급되고 상단부채반에서는 하부및 측부에서 열풍을 공급받기 때문에 전체적인 건조공간의 열풍압력편차를 크게 줄일수 있게 한 구성으로 농수산물건조를 균등하게 건조시키는 등 건조효율이 크게 향상된다.In this way, the agricultural and marine products drying apparatus of the present invention is a communication tube that passes the passage of the heating combustion gas one by one to prolong the residence period of the heat of combustion, and the vortex generation pieces twisted in the form of preheating are installed in the communication tube of the heat exchanger to facilitate heat transfer to the communication tube. In one configuration, the hot air efficiency is high, and the drying chamber is supplied with hot air only from the lower part of the lower fan and the hot air is supplied from the lower part and the side of the upper fan, while the drying chamber is mounted in multiple stages in the drying space. The drying efficiency is greatly improved by drying the agricultural and marine products evenly.
