る。Operation If the grains to be dried are now supplied into the dryer main body 101, the grains are filled into the drying passage 109, the cross-flow feed-out chamber 112, and the dryer main body 101 above the drying passage 109, and are filled into the drying passage 109 and the cross-flow feed-out chamber 112. And the entire exhaust chamber 107 is closed with grains.

以上のようにして所定量の穀物が乾燥機本体１
０１内に充填されたら、その供給を停止し熱風送
風室１０３内において乾燥熱風を起成せしめると
同時に排塵風室１０２内を負圧状態ならしめる。 As described above, a predetermined amount of grain is delivered to the dryer body 1.
01 is filled, the supply is stopped, dry hot air is generated in the hot air blowing chamber 103, and at the same time, the inside of the dust exhausting air chamber 102 is brought into a negative pressure state.

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 enters the dust chamber 102, exits from the hot air chamber 105, crosses the drying passage 109, enters the exhaust chamber 107, is sucked into the dust exhaust chamber 102 from the exhaust chamber 107, and is concentratedly discharged far outside the machine. Ru. Therefore, the grains flowing down inside the dryer main body 101 due to the grain feeding action are first divided into the hot air chamber 105 and the exhaust chamber 107, enter the front-back drying passage 109, and then enter the drying passage 109.
The grains are dried by being exposed to the circulating dry hot air as they are sequentially flowed vertically down the inside, and then after passing through the drying passage 109, the grains exhibit a so-called cross-flowing state in which the flow changes from side to side due to the chevron partition wall 111. After being deposited in the cross-flow downward dispensing chamber 112, it is sequentially discharged into the unloading chamber 119 by the dispensing action.

これが塵埃を集積せしめ除塵作業を行う。 Therefore, the flow direction of the grains when they flow down the drying passage 109 is changed to an orthogonal direction when they fall into the cross-flow dispensing chamber 112, so that grains with different initial moisture contents are transferred to the cross-flow dispensing chamber. 11
2, the grains are effectively stirred and mixed, and even grains with different initial moisture contents are dried uniformly by the drying hot air through multiple circulation flow operations without causing uneven drying. Depending on the condition, the fluidity of the grain is improved and the grain is flowed down evenly without uneven flow. 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 path 108, cross the inside of the take-out chamber 119, and further pass through the ventilation path 108.
Only dust is air-separated from the dried grains by being exposed to the dry hot air flowing towards the dust collection chamber 104 through 29, and the dust is carried to the dust collection chamber 104 by the circulating dry hot air, where the dust is accumulated and the dust removal work is performed.

それ故、取出し室１１９内に排出された乾燥穀

通する乾燥熱風でさらに乾燥が促進されるので、
これが乾燥穀物を複数回に亘り循環返流させれ
ば、穀物は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 119 contain less dust, and the drying hot air flowing across them accelerates the drying process.
If the dried grains are circulated and returned several times, the grains will be dried to a desired moisture content.

交差流下繰出し室１１２と接続せしめてある。 At a position above the space between the dust exhaust air chamber 102 and the dust collection chamber 104, a plurality of end-stopped holes are connected at one side to the dust collection chamber 104 through a ventilation window 106, facing in a direction perpendicular to the horizontal direction. Hot air chamber 105 consisting of
and a plurality of air exhaust chambers 107 connected on one side to the dust exhaust air chamber 102 through an air exhaust window 108.
are installed alternately so that a drying passage 109 is formed between the hot air chamber 105 and the exhaust air chamber 107, and the upper end side of the drying passage 109 is connected to the air conditioner formed above the hot air chamber 105 and the exhaust air chamber 107. In addition to being connected to the pawn tank 110, the lower end thereof is connected to a plurality of cross-flow downstream feeding chambers 112 formed by chevron-shaped partition walls 111 arranged in a plurality of rows along the horizontal direction directly below the hot air chamber 105 and the exhaust chamber 107. It is connected. The hot air chamber 105 and the exhaust chamber 107 both have sides facing the drying passage 109 as ventilation surfaces 113 and 1.
14 and open the lower part 115 and 11

防止できる。 Therefore, the lengths of the hot air chamber 105, the exhaust chamber 107, and the drying passage 109 can be made short, and at the same time, the number of them can be increased, so that even if the deposition pressure of the grains filled in the tempering tank 110 is high, , the ventilation window 106 and the ventilation window 1 may be able to increase their durability without causing the hot air chamber 105 and the ventilation chamber 107 to curve.
08 is also increased, the blowing resistance of the dry hot air blown from the hot air blowing chamber 103 is reduced, and the amount of air blown from the hot air blowing chamber 103 can be increased. In addition, the lower portions of the hot air chamber 105 and the exhaust chamber 107 are opened 115 and 1.
16, even if part of the dust mixed into the grain flowing down the drying passage 109 enters the hot air chamber 105 and the exhaust chamber 107 from the ventilation surfaces 113 and 114, the dust and the like will be removed from the hot air chamber 105. The dust is not deposited on the inner bottom of the exhaust chamber 107 and flows smoothly down to the lower cross-flow dispensing chamber 112, thereby preventing a fire accident in the grain dryer due to ignition and combustion of accumulated dust and the like.

ることができる効果を奏する。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 efficiently removed by dry hot air flowing across the interior toward the dust collection chamber 104. This not only allows the separated dust to be automatically collected into the dust collection chamber 104, but also further accelerates drying by blowing dry hot air again in the take-out chamber 119. be effective.
