中排塵される。By the negative pressure, the dry hot air is jetted downward in the drying passage along the grain flow direction from the jet window opening at the lower end of the hot air jet duct, and is uniformly applied to the grain. Then, the dry hot air that has flowed in parallel in the same direction as the grain flow direction along the drying passage is circulated in the cross flow delivery chamber by negative pressure, and then is exhausted into the ventilation extraction chamber. Therefore, the first co-current drying is appropriately performed in the process in which the grain is rectified by the action of the hot air blowing duct and is flowed down toward the cross flow feeding chamber along the drying passage. Then, when the grain falls into the cross-flowing feeding chamber through the drying passage, it is deflected in a direction orthogonal to the drying passage by a plurality of rows of mountain-shaped perforated partition walls arranged along the lateral direction and simultaneously dried. The dry hot air that flows in parallel in the passage smoothly flows toward the air extraction chamber in the cross-flow delivery chamber, so that the second drying is performed by the dry hot air that flows downward while being effectively stirred and mixed. In addition, the grain discharged by the feeding operation into the ventilation extraction chamber is subjected to the third drying by being exposed to the dry hot air that is sucked and distributed from the cross-flow feeding chamber to the dust extraction chamber through the ventilation extraction chamber. Dust contained in a large amount of grains is separated and sorted by the hot exhaust air that is sucked and distributed from the air extraction chamber through the ventilation window toward the exhaust air chamber, and this dust is exhausted together with the exhaust hot air from the exhaust air chamber to the outside of the machine. Be dusted.

ける。By the way, the lower part of the dust exhaust chamber is divided into a side close to the suction / exhaust device and a side far from the suction / exhaust device by a standing wall, and the near side becomes a dust accumulation suction chamber with an open upper surface, and also a far side. Is installed in the bottom of the ventilation extraction chamber along the front-rear direction by a ventilation slant plate that is installed obliquely toward the lower conveyor gutter, so the suction action of the suction and exhaust device causes the dust accumulation suction chamber through the ventilation window. The dust that was about to enter and accumulate is blown out with a strong suction force and is discharged outside the machine along with the exhaust hot air.At the same time, it passes through the ventilation window and is placed on the ventilation inclined plate located farther from the suction and exhaust device. A part of the discharged dust is sucked into the dust accumulation suction chamber by the suction air flowing toward the air exhaust device on the ventilation inclined plate from the ventilation window, and the other slides on the ventilation inclined plate toward the lower conveyor gutter. Bottom conveyor without falling down and accumulating Receiving the selected action is conveyed again by the.

を長期に亘り継続することができる。Therefore, even during the grain drying operation as described above,
Since the accumulation of dust in the dust exhaust chamber located farther than the suction / exhaust device is prevented as much as possible, the smooth grain drying operation can be continued for a long period of time.

After the grain flow divided in the front-rear direction in the drying passage 7 has passed through the drying passage 7, this time the flow is changed to the left-right direction so that it cross-flows down, and grains with different initial moisture contents are efficiently stirred and mixed, and at the same time, the grains are mixed. Improve the liquidity of
The grain can be dried uniformly without unevenness in drying and unevenness in flowing. In addition, in the cross-flowing delivery chamber 8,
Since the grain that has been deflected downwards through the drying passage 7 is always filled, the grain is evenly exposed to the dry hot air flowing in the crossflow feeding chamber 8 through the drying passage 7 from the hot air jet duct 6 to damage the grain. It is dried uniformly without being processed.

置。1. A hot air blower chamber having a burner device on one side and a dust blower chamber having a suction / exhaust device on one side are provided at opposing positions on both left and right sides in a dryer main body which is long in the front-rear direction. Between the hot air blowing chamber and the dust exhaust chamber, a ventilation drying unit, a cross-flow downflow chamber, and a ventilation extraction chamber connected to the dust ventilation chamber through a ventilation window were sequentially arranged three-dimensionally from the upper stage to the lower stage. In the dust exhaust air chamber, the lower half portion is divided into a side closer to the suction and exhaust device and a side farther by the standing wall, and the near side is a dust accumulation suction chamber whose upper surface is open, and the far side. Is a grain dryer equipped with an inclined ventilation plate that is installed obliquely toward the lower conveyor gutter that is installed along the front-rear direction at the bottom of the ventilation extraction chamber.
