いた。 Moreover, in the case of conventional grain dryers of this type,
Normally, tempering tanks for temporarily storing dried grains do not allow drying hot air to flow through them, but only allow moisture to diffuse and move within the grains themselves. This had the problem that the acceleration of drying could not be further improved.

ようとするものである。 The present invention has been made in view of the problems of the conventional technology, and its purpose is to separate the flow of grains into the 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 from left to right, improves the fluidity of high-moisture grains and performs efficient drying, it is necessary to use a suction exhaust system to remove the dust contained in the grains. The suction action of the dust exhaust air chamber passes through the take-out tank, and the exhaust hot air is discharged to the outside.The wind selection action of the exhaust hot air quickly separates and removes the grain, and the grain flows in parallel with the grain flowing down the tempering tank. The purpose of the present invention is to provide a grain dryer that can rapidly achieve more uniform drying work by actively spraying hot drying air.

へ向け集中排塵せしめる。 Therefore, the grain flow direction when the grains, which have been dried to some extent by the dry hot air flowing in parallel in the conditioning tank 109, flows down the drying passage 108 changes to a direction perpendicular to the grains when they fall into the cross-flow feed-out chamber 111. Therefore, grains with different initial moisture contents are effectively stirred and mixed when they fall into the cross-flow feed-out chamber 111, 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 118 are exposed to the exhaust hot air flowing from the dust-exhausting air chamber 103 across the inside of the take-out chamber 118 toward the suction exhaust fan 125. Only dust is air-separated from the dried grains, and the dust is then centrally discharged to a distant place outside the machine by a suction exhaust fan 125.

所要の含水率に乾燥されるものである。 Therefore, the dried grains discharged into the take-out chamber 118 contain less dust, and the drying hot air flowing across the grains further accelerates drying.
By circulating and returning the dried grains several times, the grains can be dried to a desired moisture content.

防止できる。 Therefore, the lengths of the hot air chamber 104, the exhaust chamber 106, and the drying passage 108 can be shortened, and at the same time, the number of them can be increased to increase the pile pressure of the grains filled in the tempering tank 109. Also, in order to increase the durability of the hot air chamber 104 and the ventilation chamber 106 without curving, the number of the ventilation windows 105 and the ventilation windows 107 is also increased so that the dry hot air blown from the hot air ventilation chamber 102 can be increased. By reducing the blowing resistance, the amount of air blown from the hot air blowing chamber 102 can be increased. In addition, by opening the lower portions 114 and 115 of the hot air chamber 104 and the exhaust chamber 106, some of the dust mixed in the grain flowing down the drying passage 108 is transferred to the ventilation surface 112.
Even if the dust enters the hot-air chamber 104 and the exhaust chamber 106 from the hot-air chamber 104 and the exhaust chamber 106 from the hot-air chamber 104 and the exhaust chamber 106, the dust and the like do not accumulate on the inner bottom of the hot-air chamber 104 and the exhaust chamber 106, and all of them smoothly flow into the lower cross-flow discharge chamber 111. It is possible to prevent fire accidents in grain dryers due to ignition and combustion of accumulated dust etc. by flowing down.

させることができる。 Moreover, the hot air chamber 104 and the exhaust air chamber 106
Since the cross-flow feed-out chamber 111 is formed directly under the drying passage 108, after passing through the drying passage 108, the flow of grain is changed to the left-right direction and made to cross-flow. It is possible to efficiently stir and mix grains having different initial moisture content values, improve the fluidity of the grains, eliminate uneven drying and uneven flow of the grains, and dry the grains uniformly.

その上、さらに、交差流下繰出し室１１１内に

ラを皆無な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 108 is made as large as possible, and even if the amount of hot air generated is the same, a large amount of hot air is blown into the hot air chamber 104 with less air loss. In order to improve the drying ability by supplying the grains to the same source, even if the grains have high moisture contents with different initial moisture contents, the flow of grains divided into the front and rear directions in the drying passage 108 is divided into two directions. Even if the grain dryer is capable of uniformly drying all the grains without causing uneven drying by flowing the grains down in a crosswise manner so that the flow changes from side to side after passing through 108, and stirring and mixing the grains,
By connecting the dust exhaust air chamber 103 and the extraction chamber 118 equipped with a suction/exhaust fan 125, the exhaust hot air is directed from the extraction chamber 118 toward the suction/exhaust fan 125 by the suction action of the suction/exhaust fan 125, and the exhaust air flows into the extraction chamber. 1
A large amount of the dust contained in the dried grains discharged in a scattered state inside the machine can be efficiently removed by wind separation, and the separated dust can be centrally discharged far outside the machine. At the same time, exhaust hot air is extracted from the extraction chamber 118.
Of course, it is possible to accelerate drying by spraying the grains discharged into the tank, and also in the tempering tank 109, a plurality of rows of spouting bodies 12 are applied to the grains flowing vertically down.
8... By making the drying hot air flow in parallel, drying can be made more uniform and the acceleration of drying can be further improved. By surrounding it with a double layer structure, it is possible to prevent condensation from occurring and eliminate uneven flow.
