According to the present invention, the method of dry storage of grain in a hopper bin repeats the re-injection of the stored grain through the lower portion of the hopper bin so as to prevent deterioration of the stored grain and re-injected onto the grain stored in the hopper bin through the transfer means and the lifting means. The upper and lower grains are circulated, and forced air is blown into the inside of the hopper bin by a blowing means so that air is discharged to the outside through the outlet through the grain particles, and the grains are stored at room temperature ventilation circulation drying.

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in more detail the present invention.

The grain dry storage device 1 of the present invention shown in FIGS. 1 to 3 includes a hopper bin 3 installed at a position raised from the ground by a plurality of supports 2 and having a lower portion formed as a funnel. do. One side of the hopper bin (3) is provided with a hopper (5) is fixed to the bucket elevator (4) for feeding the grain into the hopper bin and the grain is loaded in the bucket to be elevated at the lower end. The grain outlet 6 formed at the bottom of the hopper bin is provided with a screw conveyor 7 as a grain conveying means so that the grain discharged from the outlet is returned to the hopper bin 3 by the space at the bottom of the bucket elevator 4. The grains stored in the hopper bin with the bucket elevator are circulated to dry.

The bucket elevator 4 is configured to move a plurality of buckets connected to each other inside the tubular housing, such a bucket elevator itself is conventional. A driving means 8 is provided at the upper end of the bucket elevator to lift the buckets containing the grains from the hopper 5 to the top, while unloading from the top and then descending again. In addition, the upper portion of the bucket elevator (4) is in communication with the input pipe (9) for re-injecting the grain lifted by the bucket back to the hopper bin (3) and the discharge pipe (10) for discharging the outside to unload the grain. In addition, the direction changer 11 is provided to selectively open and close the input pipe and the discharge pipe to selectively automate grain unloading operations and grain circulation drying operations, thereby reducing labor and improving work efficiency and improving energy. Can be saved. When the grains are stored in the hopper bin 3 for a long time by circulating and uniformly drying the grains stored in the hopper bin 3 by the screw conveyor 7, the bucket elevator 4, and the input pipe 9. It prevents the deterioration of the grain and keeps the high quality.

The hopper bin (3) is forcibly blown outside air to prevent the deterioration of the grain stored therein, for this purpose, a blower (12) is mounted on the outer middle portion of the hopper bin and the blower tube (13) is connected to the discharge port, the blower tube Extends into the interior space of the hopper bin 3 and is perforated with holes 14 having a smaller diameter than the grain to draw the outside air blown by the blower 12 into the grain contained in the hopper bin 3 and to the grain. By passing between the particles and gathering into the empty space at the top of the hopper bin, the moisture is removed from the grain, thereby uniformly drying the inner and outer grains in the hopper bin.

In addition, the support (2) fixed to support the hopper bin (3) consists of a tubular body, the upper end of which communicates with the internal space of the hopper bin, while the discharge port (14) is formed at the lower side, the hopper by the above-described blower The air that is blown into the bin passes through the grain particles and collects into the upper space of the hopper bin to allow the air to exit outside the hopper bin. The hopper bin may be formed of a glass fiber reinforced plastic material to reduce the burden of the installation cost, wherein the plurality of spaced annular metal frame to connect to the support to be fixed, and also using a connector so that the bucket elevator is supported by the support can do.

4 is an improved structure to improve the ventilation drying effect than the embodiment of FIG. Unlike the hopper bin 3 of FIG. 1, the lower part of the hopper bin 3 ′ does not have a hopper shape, but a hopper shape therein, so that the diameter of the hopper bin 3 is narrowed toward the outlet 6 and smaller than the grain particles. A perforated plate element 15 is provided in which a plurality of holes 16 of diameter are formed so that air can be drawn in. Therefore, the air blown from the blower 12 mounted near the ground flows into the empty space between the bottom surface of the hopper bin 3 'and the drilling plate element 15, thereby opening the holes 16 of the drilling plate element 15. The air drying effect is improved in the embodiment of FIG. 1 because the grains are uniformly dried while moving upwardly through the pores between the grain particles accumulated in the hopper bean 3 '. In addition, in the present embodiment, a small hopper 17 is mounted on one side of the hopper bin 3 'for loading and temporarily storing grains discharged from the discharge pipe 10 for loading and unloading. Even during the replacement time, the bucket elevator 4 can be temporarily stored in the hopper 17 without stopping the container 4, and in the embodiment shown in FIG. 1, when the container is replaced, grains discharged from the discharge pipe fall to the ground and are wasted. There is an effect that can be prevented.

There are two methods for dry storing the grains of the hopper bins 3 and 3 'by the grain dry storage device configured as described above.

The first is to dry the grains by blowing air at room temperature into the hopper bin (3, 3 ') while continuously circulating the grains for rapid drying of the grains. In this case, the diverter 11 provided at the top of the bucket elevator 4 is switched so that the grain lifted from the bucket elevator is introduced into the hopper bins 3 and 3 ', and the outlet 6 at the bottom of the hopper bin is opened. Open and operate the screw conveyor (7) to direct the grain discharged from the outlet to the bucket elevator (4) and start the bucket elevator to fill the bucket with the grain discharged from the hopper (5) while holding the grain at its bottom. Lifting and re-inserting into the hopper bin (3, 3 ') is carried out repeatedly, wherein the air blower 12 is operated to blow the outside air into the hopper bin, in particular below the middle position through the grain particles Gathered and discharged to the outlet 14 of the support (2) to uniformly mix the grain stored in the upper and lower portions of the hopper bin, and the drying speed is fast and uniform grain dry storage It is.

In the second method, the grains are intermittently circulated and air is continuously supplied into the hopper bins 3 and 3 'to dry and store the grains. At this time, only the blower 12 is operated first so that the outside air flows into the inside of the hopper bin through the porous blower tube 13 or the perforated plate element 15 installed inside the blower and the hopper bins 3 and 3 'and passes through the gap between the grains. Dehydration from the grains, and then through the outlet 14 of the support 2 in communication with the top of the hopper bins 3, 3 '. In this case, the grain at the bottom of the hopper bin (3,3 ') dries faster than the grain at the top of the hopper bin, so the screw conveyor (7) and the bucket elevator (4) are operated over time to allow the grain in the hopper bin to The hopper is repeatedly circulated, that is, discharges the grain at the bottom of the hopper bin, puts it back into the top of the hopper bin, and sends the grain at the top of the hopper bin (3, 3 ') to the bottom of the hopper bin at regular intervals. Ensure the grain drying in the bins is uniform.

This method can be carried out intermittently over a period of time in the long term storage of grain. For example, when long-term storage of grain has a long day of high humidity, such as the rainy season, or when there is a possibility that condensation may appear inside the hopper bin due to a large crossover, operate the blower on a good day to operate the inside of the hopper bin. The outside air is blown out to prevent moisture from being deteriorated during storage.

According to the present invention, using a hopper bin having a funnel shape in the lower part, there is no residue when discharging grains and there is no limitation in the installation height so that it can be installed in a narrow space, thereby minimizing the installation area, and by a blower and a porous ventilation pipe The air is forced into the middle of the hopper bin to pass through the stored grains to dry the grains. Drying is uniformized, and thus, by using a combination of air-ventilated drying and grain circulation by a blower as needed, the grain quality is not degraded even during long-term storage and the drying and loading and unloading operations are automated to save labor. And energy savings.
