The means disclosed in Japanese Patent Application Publication No. 4 (1999) -1995 discloses that, when a grain drying operation is performed using the grain storage / drying device configured as described above, the grain initially loaded into the grain basin a is the full volume of the grain basin a. First, the grain is dried, and when the grain has dried to a certain extent, undried grains are added so as to be added. Proceed with the drying process while stirring and mixing with the grains whose drying is in progress.Additionally, successively adding undried grains so that the drying process proceeds, and perform the cumulative stirring. This is a means for drying the undried grains while storing the dried grains in the grain tank a by performing drying.

As shown in Fig. 2, when additional grains are added one after another and the drying operation is performed, the drying rate slightly decreases, but the drying capacity is reduced by drying the first one-fifth. The advantage is that the ability to dry the whole grain is maintained, while keeping it almost unchanged from its ability to do so.

Area Y just above the floor plate 20 within the range of the rotation locus of
Therefore, the area Y is a non-stirring area where the stirring and mixing of the grains are not performed, and the grains that are immovably deposited in the area Y are indicated by a dashed line in FIG. As shown in (1), there is a problem that it is excessively dried to a remarkably low moisture value, and that the whole is uniformly dried to a predetermined moisture value.

問題がある。Further, while drying the grains stuck in the grain tank a, the undried grains are successively added so as to be added and accumulated, and then blown up from the lower surface of the floor plate 20 of the grain tank a. Since the drying is promoted by the drying air, every time the grains are put into the grain tank a so that the undried grains are added,
The dust mixed in the grain rises into the grain tank a and becomes full, so that the exhaust discharged to the outside from the exhaust port 24 contains a large amount of dust, and is discharged together with the exhaust. There is a problem that processing of a large amount of dust is troublesome.

The present invention is directed to a discharge auger 3 disposed on a floor plate 20 below the lower end of a vertical auger 41. Since the grains in the area Y just above the floor plate 20 located in the orbit of the orbital rotation are kept in the stationary state during the drying process, the grains in the area Y are effectively removed. By using the new method, a large amount of dust that rises and fills the grain tank a every time the grains are added to the grain tank a so as to be added thereto can be removed from the exhaust gas. It is intended to provide a means.

は逆になる。The vertical cylindrical grain storage and drying apparatus A according to the present invention having the above-described structure is provided with a predetermined amount of grains smaller than the total capacity of the grain basin a in the grain basin a by the conveyer 5. , And the grains are dried by feeding dry air or natural outside air into the grain tank a while stirring and mixing by the operation of the vertical auger 41. At the point where the process has progressed, the drying process is continued by adding the undried kernels so as to be added, and by repeating the process, all of the kernels introduced into the cereal tank a by the cumulative stirring and mixing method are subjected to a predetermined process. With respect to the use of the grains dried to the moisture content and then dried out by the operation of the discharge conveyor 22 and the discharge auger 3, the conventional vertical cylindrical shape shown in FIG. Is the same as the grain storage and drying unit A But, it is opposite to the direction of the drying air or natural of the outside air flow feeds for Zhang elaborate grain in the Kokuso a.

By the operation of the suction blower 7 connected to 0, the grain layer deposited on the floor plate 20 and inserted into the grain tank a is first transmitted through the area W to be stirred and mixed by the vertical augers 41. Then, through the area Y just above the floor plate 20 where there is no movement of the grain, and flow out to the air guide passage b below the floor plate 20,
The light is transmitted downward from above.

When it is discharged to the outside together with the exhaust air of the dry air that has passed through the grain layer, by passing through the grain layer in the immovable area Y,
The grain layer in this section Y is used as a filter, filtered and removed from the exhaust air, and the exhaust air discharged from the air guide path b to the outside is kept in a dust-free state.

の処理を著しく容易にする。As described above, in the means of the present invention, the grain layer in the area Y just above the floor plate 20 which is not moved without being subjected to the stirring / mixing action is stored in the grain tank a. Each time a grain is thrown in, the dust generated in the grain tank a becomes a filter that adsorbs and separates, so that the exhaust air of the dry wind discharged to the outside through the air guide path b below the floor plate 20 removes the dust. As a result, the dust discharged to the outside together with the exhausted air can be effectively removed, and the processing of the dust and the exhausted air is significantly facilitated.

塵方法。1. An air-permeable floor plate 20 having a discharge port 21 at a center portion is provided on the bottom side of a lumen of a cylindrical bottle main body 2 whose axial direction is a vertical direction. A vertical auger that forms a grain trough a into which grains are inserted upward, and also forms an air guide path b below the floor plate 20, and agitates and flows the inserted grains vertically in the grain trough a. And the lower end of the vertical auger 41 and the floor plate 20
A discharge auger 3 is mounted between the upper surface of the bottle main body 2 for revolving and rotating around the upper surface of the floor plate 20 around the upper surface of the floor 21 to transfer the grains toward the discharge port 21. An air outlet c for supplying dry air is provided at the upper part of the inner cavity, and a suction port 70 of the suction blower 7 is connected to an air guide path b below the floor plate 20, so that the kernels are put into the grain tank a. The dry air supplied from the air supply port c at the top of the inner cavity of the bottle main body 2 is fed into the grain tank a while being stirred and mixed vertically by the vertical augers 41. Floor plate 20 from above the grain layer
Non-circulation characterized in that dust generated in the grain basin (a) at the time of grain input is removed from the exhaust air by flowing the grain toward the lower air guide path (b) to dry the grain. -A dust removal method in a vertical cylindrical grain storage and drying device of a cumulative stirring and mixing system.
