る。 The present invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to separate the grain flow, which is divided into front and back directions in the drying passage, after passing through the drying passage. Even if the so-called cross-flow method, in which the flow changes in one direction, improves the fluidity of high-moisture grains and performs efficient drying, the dust contained in the grains can be removed from the hot air blowing chamber. The grains are quickly sorted and removed by the wind selection action of the dry hot air that flows through the extraction chamber to the dust collection room, and the clean dry hot air that flows parallel to the grains flowing vertically in the tempering tank is actively sprayed. , it is an object of the present invention to provide a grain dryer that can quickly accomplish a more uniform drying operation.

に順次排出される。 Then, the dry hot air generated in the hot air blowing chamber 103 passes through the hot air blowing chamber 103, the extraction chamber 119, and the dust collection chamber 104 into the plurality of hot air chambers 105 due to the negative pressure action in the dust exhausting chamber 102. The dust then exits from the hot air chamber 105, crosses the drying passage 109, enters the exhaust chamber 107, is further sucked into the dust exhaust chamber 103 from the exhaust chamber, and is then concentratedly exhausted to a far distance outside the machine. On the other hand, a part of the dry hot air is blown from the dust collection chamber 104 into the plurality of rows of blowing bodies 130 . Therefore, the grains that are vertically flowed down inside the tempering tank 110 by the grain feeding action are ejected from the plurality of rows of ejection bodies 1.
30... After being dried by being exposed to drying hot air flowing in parallel, it is divided into a hot air chamber 105 and an exhaust chamber 107, enters a front-back drying passage 109, and then is sequentially flowed down vertically in the drying passage 109. In the process, it is exposed to the circulating dry hot air and is then dried in the drying passage 109.
After passing through the grain, the grain passes through the chevron partition wall 11.
1, the particles are deposited in the cross-flow feed-out chamber 112 while exhibiting a so-called cross-flow state in which the flow changes in the left-right direction, and then sequentially discharged into the take-out chamber 119 by the feed-out action.

う。 Therefore, the flow direction of the grains, which have been somewhat dried by the dry hot air flowing in parallel in the tempering tank 110, when they flow down the drying passage 109 changes to a direction perpendicular when they fall into the cross-flow feed-out chamber 112. Therefore, grains with different initial moisture contents are effectively stirred and mixed when they fall into the cross-flow feed-out chamber 112, and even grains with different initial moisture contents can be mixed by drying hot air by multiple circulation flow operations. The grains are dried uniformly without uneven drying, and at the same time, the fluidity of the grains is improved due to the cross-flow condition, and the grains are evenly flowed down without uneven drying. The dried grains containing a large amount of dust discharged in a scattered state into the take-out chamber 119 pass from the hot air blowing chamber 103 through the ventilation passage 128, cross the inside of the take-out chamber 119, and further pass through the ventilation passage 129 to the dust collection chamber. The dust is separated from the dried grains by being exposed to the dry hot air flowing towards the dust collection chamber 104.
04, where it collects dust and performs dust removal work.

らしめる等の効果を奏する。Effects of the invention In short, the present invention has the above-mentioned technical means, so that the area of the drying passage 109 is made as wide as possible, and even if the amount of hot air generated is the same, a large amount of hot air can be delivered into the hot air chamber 105 without blowing loss. It is possible to improve the drying capacity by supplying a small amount of grain to each other, even if the grain has a high moisture content and has a different initial moisture content. Even if the grain dryer is capable of uniformly drying all grains without causing drying unevenness by flowing down in a crosswise manner so that the flow changes from side to side after passing through the passage 109 and agitating and mixing the grains, the hot air By configuring the ventilation chamber 103, the extraction chamber 119, and the dust collection chamber 104 to be connected to each other, the extraction chamber 119 is connected to the hot air ventilation chamber 103.
A large amount of dust contained in the dried grains discharged in a scattered state into the take-out chamber 119 is removed with high efficiency by the dry hot air flowing across the inside and toward the dust collection chamber 104. Not only can the separated dust be automatically collected in the dust collection chamber 104, but also drying can be further promoted by blowing dry hot air again in the extraction chamber 119. Also in the grain tank 110, dry hot air that has been removed and cleaned in the dust collection chamber 104 is made to flow in parallel against the vertically flowing grains from multiple rows of jetting bodies 130... to prevent dust from entering. It is possible to prevent uneven flow as much as possible, improve uniformity of drying and promotion of drying, and at the same time surround the tempering tank 110 with a dust exhaust air chamber 102 and a dust collection chamber 104 to create a double structure. This has the effect of preventing dew condensation and further eliminating uneven flow.
