본 고안은 오일버어너와 송풍기가 구비된 농산물의 건조기에 있어서, 열풍통로와 열풍 분배실이 교호로 구분 형성된 열풍 분배판을 건조실의 내부에 상하 일정한 간격의 병열로 송풍로와 연관되게 형성하고 열풍 분배판 사이에 농산물 건조 상자를 재치할 수 있게 구성하여 건조실의 상하 좌우 전체공간의 온도분포를 균일하게 유지시키어 건조상자를 상하 교체함이 없이 능률적으로 농산물을 고품질로 건조할 수 있게한 농산물 건조기의 열풍 송풍장치에 관한 것이다.The present invention is a dryer of agricultural products equipped with an oil burner and a blower, the hot air distribution plate formed by alternating hot air passage and hot air distribution chamber is formed in the drying chamber in parallel with the vertically spaced intervals in parallel with the blower and hot air The agricultural product drying box can be placed between the distribution boards so that the temperature distribution of the entire space of the upper, lower, left and right sides of the drying room is maintained uniformly so that the product can be dried at high quality efficiently without replacing the upper and lower drying boxes. It relates to a hot air blower.

종래의 농산물 건조기는 상하 여러층으로 건조상자를 재치하게 된 건조실의 하부측에서 열풍을 송풍하여 건조실의 상부로 배출하게 된 단순 순환구조로 되어 있어 건조실의 상부와 하부 측의 온도 편차가 커서 수시로 건조실의 상부측과 하부측의 건조상자를 상하로 교체하면서 건조해야 하기 때문에 건조작업에 인력이 많이 들고 능률적으로 건조하기 어려울뿐 아니라 건조과정에서 농산물의 품질이 저하될 우려가 있는 문제점이 있었다.The conventional agricultural product dryer has a simple circulation structure in which hot air is blown from the lower side of the drying chamber where the drying box is placed in several layers above and below and discharged to the upper part of the drying chamber. Since the drying box of the upper and lower sides of the upper and lower sides should be dried while drying, it is difficult to dry a lot of work efficiently and efficiently, and there is a problem that the quality of agricultural products may be degraded during the drying process.

또한 건조실 내부에서 건조상자가 무단 회동되는 체인에 의하여 내부적으로 자동 순환되는 순환식 건조기가 있으나 건조상자를 동력으로 순환하기 위한 구동장치와 순환기구등의 부수장치의 건조기의 값이 경제적으로 높게되는 문제점이 있었다.In addition, there is a circulating dryer that automatically circulates internally by a chain in which the drying box is rotated in the drying chamber, but the value of the dryer of the auxiliary device such as the driving device and the circulation device for circulating the drying box by power is economically high. There was this.

또한 건조기의 좌우에 다공성의 측벽으로된 건조실을 형성하여 건조실의 중간부에서 송풍기에 의하여 건조실의 사방 측면내부로 열풍을 공급하게 된 것도 있으나 열풍의 비중관계로 건조실 내부 깊숙히 전달되지 못하고 건조실의 상부측으로 열이 집중되는 폐단이 있었다.In addition, the drying chamber is formed on the left and right sides of the dryer and the hot air is supplied from the middle of the drying chamber to the four sides of the drying chamber by the blower. However, due to the specific gravity of the hot air, the drying chamber is not transmitted deeply to the upper side of the drying chamber. There was a congestion of heat.

도면중 미설명 부호 14는 재치대, 15는 농산물 건조상자이다.In the figure, reference numeral 14 denotes a mounting table, and 15 denotes a agricultural product drying box.

본 고안의 실시에 있어서 건조실(8)은 한칸으로 형성할수도 있고 2칸 이상의 여러칸으로 형성할수도 있으며 각 건조실의 칸을 분리 결합 되게 형성할수도 있다.In the practice of the present invention, the drying chamber 8 may be formed in one compartment or may be formed in two or more compartments, or may be formed to separate the compartments of each drying chamber.

이와 같이된 본 고안은 건조할 농산물을 담은 상자(15)을 건조실(8)의 재치대(14)에 일정한 간격으로 재치하고 오일버어너(3a)와 송풍기(2a)를 가동하면 공기흡입구(4)를 통하여 흡입된 공기는 가열실(3)에서 오일버어너(3a)의 열에 가열되는 동시 송풍기(2a)에 의하여 송풍실(2)에서 송풍로(7)로 송풍된다.According to the present invention, the box 15 containing the agricultural products to be dried is placed on the mounting table 14 of the drying chamber 8 at regular intervals, and the oil burner 3a and the blower 2a are operated. The air sucked through) is blown from the blower chamber 2 to the blower 7 by a simultaneous blower 2a which is heated to the heat of the oil burner 3a in the heating chamber 3.

송풍로(7)에는 안내판(7a)에 의하여 하부에서 상부로 순차적으로 적은 풍량으로 열풍이 각각 나누어 건조실(8)에 설치된 열풍 분배판(9)의 유입구(9a)로 유입된다. 이때 건조실(8)의 가장 하단부의 열풍통로(11a)로 유입된 1차 열풍은 안내판(13a)에 의하여 건조실의 좌우가 거의 균일하게 다공성 분배판(12c)을 통하여 상승된다. 또한 각 열풍통로(11)의 유입구(9a)로 유입된 1차 열풍은 열풍통로(11)에 형성된 안내판(13)에 의하여 좌우 균일한 분포로 분배하여 다공성 상판(12b)을 통하여 상승된다. 이때 하부에서 상승되는 2차 열풍은 다공성 밑판(12a)을 통한 후 다공성 상판(12b)을 통하여 상승하여 분배판(9)의 열풍통로(11)에서 상판(12b)으로 분산된 1차 열풍과 혼합되어 건조실 상부측으로 이동하면서 건조상자(15)에 담은 농산물을 건조한다. 이때 각 열풍 분배판(9)이 설치된 공간마다 동일 온도의 1차 열풍이 공급분배되므로 건조실(8)내부 공간은 상하구분 없이 균일한 온도분포를 유지하게 되어 건조과정에 상하측의 건조상자를 상호 교체하지 않고 제자리에서 동일한 온도조건으로 건조하게 된다.Hot air is divided into the air blower 7 by the guide plate 7a sequentially from the lower part to the upper part, and flows into the inlet port 9a of the hot air distribution plate 9 installed in the drying chamber 8. At this time, the primary hot air introduced into the hot air passage 11a at the bottom end of the drying chamber 8 is elevated through the porous distribution plate 12c by the guide plate 13a almost evenly. In addition, the primary hot air introduced into the inlet (9a) of each hot air passage 11 is distributed in a uniform left and right distribution by the guide plate 13 formed in the hot air passage 11 is raised through the porous top plate (12b). At this time, the secondary hot air rising from the lower portion is raised through the porous base plate 12a and then mixed through the porous top plate 12b and mixed with the primary hot air dispersed from the hot air passage 11 of the distribution plate 9 to the top plate 12b. Then, the agricultural products contained in the drying box 15 are dried while moving to the upper side of the drying chamber. At this time, since the primary hot air of the same temperature is distributed to each space where the hot air distribution plates 9 are installed, the interior space of the drying chamber 8 maintains a uniform temperature distribution without the upper and lower divisions. It is dried in the same temperature condition in place without replacement.

농산물의 건조에 따라 발산된 습기를 함유한 공기는 일부는 건조실(8)의 상부를 통하여 송풍로(7)의 상단부측 배출구(6)로 배출되고 일부는 배출조절구(6a)의 조절에 따라 공기 흡입구(4)에서 흡입되는 외부공기와 함께 송풍실(2)로 환류되어 재가열된 다음 재 공급되는 것으로 건조실의 상하 공간에 일정한 간격의 병열로 열풍 분배판을 설치하고 이 분배판은 열풍 통로와 분배실이 교호로 형성되어 있기 때문에 건조실의 상하공간에서는 병열로 설치된 여러개의 각 열풍 분배판에서 분배된 1차 열풍에 의하여 상하 균일한 온도분포를 이루고 또한 건조실의 평면 공간에서는 열풍 분배판의 일정한 좌우 간격으로 형성된 열풍통로에서 공급된 1차 열풍에 의하여 전후 좌우 평면적으로 균일한 온도분포를 이루어 건조실의 어느 부위에서나 온도분포가 동일하게 유지되어 건조실 내의 모든 건조상자의 농산물이 상하 교체 없이 동일한 온도조건에서 고품질로 건조되고 또한 건조과정에서 건조상자의 상하 교체 작업이 생략됨으로 그만큼 인력이 절감되어 보다 경제적으로 다량의 농산물을 양호하게 고품질로 건조할 수 있는 효과가 있다.The air containing moisture emitted by the drying of the agricultural products is discharged to the outlet 6 of the upper end of the air blower 7 through the upper part of the drying chamber 8, and part of the air is controlled by the discharge regulator 6a. It is refluxed to the blower chamber (2) and reheated together with the outside air sucked from the air inlet (4), and then re-supplied. The hot air distribution plates are installed in parallel spaces at upper and lower spaces of the drying chamber. Since the distribution chambers are formed alternately, uniform temperature distribution is made up and down by the primary hot air distributed in several hot wind distribution plates arranged in parallel in the upper and lower spaces of the drying chamber. The uniform temperature distribution is made in the front, rear, left and right planes by the primary hot air supplied from the hot air passages formed at intervals so that the temperature distribution is the same in any part of the drying chamber As the agricultural products of all drying boxes in the drying room are dried in high quality under the same temperature condition without changing up and down, and the upper and lower replacement work of the drying boxes is omitted during the drying process, manpower is saved so that a large amount of agricultural products are made in high quality. It has the effect of drying.
