[0002] In order to prevent the moldy deterioration of the dehulled corn during storage, drying is needed to reduce the moisture content before storage.

[0003] The dryer is a device that uses machinery to reduce the moisture content of corn kernels to a safe range for packaging and safe storage, thereby maintaining the vitality and activity of corn, greatly improving productivity, enhancing the quality of corn, reducing post-production losses, ensuring high yields, and speeding up the circulation of corn, which is of great significance.

[0004] The current common corn drying equipment is divided into: 1) cross-flow grain drying technology, which makes wet grains flow from the top of the bin to the drying section by gravity, hot air passes through the grain layer transversely through the heating section, and cold air passes through the grain layer transversely through the cooling section. 2) Downstream grain drying technology, which keeps the direction of hot air and grain flow the same, the hottest air always contacts the wettest grain first, so a very high hot air temperature can be used. 3) Counter-flow grain drying technology, which makes the flow direction of hot air and grain opposite, so the hottest air always contacts the driest grain first, the grain temperature approaches the hot air temperature, the hot air temperature cannot be too high, the grain and hot air movement trajectories are parallel, and all grains are subjected to the same drying treatment during flow. 4) Mixed-flow grain drying technology, which makes the drying equipment versatile, adopts a building block structure, and is designed as a standardized tower section; the grain layer is thin, the tower is arranged with staggered exhaust and intake angular boxes, the grains flow in an "S" shape, and are alternately subjected to high-temperature and low-temperature air flow, which can use a higher hot air temperature.

[0005] Most of the above drying equipment has the problems of uneven heating of corn, slow evaporation of water, insufficient utilization of drying waste heat, waste of energy, and no corn preheating program, so that the corn will explode when it encounters high temperature instantaneously, therefore, the present application provides a corn drying device that can heat corn evenly, reduce the explosion rate, and effectively utilize the drying waste heat, which has a positive significance for the field of agricultural product processing technology.

[0006] Therefore, the present application provides a corn drying system capable of fast and uniform drying. SUMMARY

[0014] The fallen corn falls on the upper side of the upper grid, and in the inclined state of the upper grid, slides along the helical strip on the upper grid to the center of the upper grid, which can greatly increase the path of the corn falling, increase the falling and drying time by increasing the falling path, so that the corn can be fully dried, and the falling path of each corn is the same, thereby increasing the drying effect and achieving uniform drying.

[0015] The present application also has a leak hole on the inner side of the helical strip, and for some small diameter corn, because the moisture content of small diameter corn is relatively small, the drying time required is also relatively small, the small diameter corn in the present application can directly pass through the inner side of the helical strip, thereby reducing the drying time and path of small diameter corn, avoiding excessive drying of small diameter corn, and further increasing the uniformity of the moisture content of the dried corn.

[0016] In the present application, the helical strip can also be in sliding connection with the upper grid, and the helical strip is fixedly connected with the upper rotating ring to keep synchronous movement, and when the upper rotating ring and the helical strip rotate, the corn is forced to slide on the inner diameter of the helical strip, preventing the corn from being blocked due to excessive friction on the inner diameter of the helical strip, and the blocking can also be realized by increasing the downward inclination of the upper grid;

[0027] Under the above settings, the rotating mode of the upper and lower rotating rings in the application is that the motor rotates, the motor drives the gear to rotate, and the rotation of the gear drives the upper rotating ring to rotate.

[0033] Compared with the prior art, the application has the following advantages:

[0034] 1. The corn drying system capable of fast and uniform drying, when the application is used, the corn to be dried is first placed in the pre-storage space between the preheating cone and the inner side of the top end of the drying cylinder, then the heating cylinder is worked to make the air outlet disc blow out hot air, the hot air goes upwards in the inner side of the drying cylinder, and the hot air preheats the preheating cone after passing through the spiral channel in the inner side of the preheating cone, so that the preheating cone preheats the corn in the pre-storage space, thereby preventing the corn from exploding when it instantaneously encounters high temperature, and the preheating process can be parallel to the subsequent drying process.

[0035] 2. This corn drying system, capable of rapid and uniform drying, controls the rotation of a motor. When the motor rotates, it drives the upper rotating ring to rotate. As the upper rotating ring rotates, when the through hole on the upper rotating ring connects with the feeding hole at the edge of the preheating cone, the corn moves downward under the action of gravity. Initially, the through hole on the upper rotating ring is offset from the preheating cone to allow the corn to be placed in the pre-storage space. The falling corn will land on the upper grid. With the upper grid tilted, it slides along the spiral inner radial direction of the upper grid to the center of the upper grid. This setting can greatly increase the path that the corn takes when falling, thereby increasing the time for falling and drying, so that the corn can be fully dried. Each corn has the same falling path, thus increasing the drying effect and achieving uniform drying.

[0036] 3. In this invention, a corn drying system that can dry corn quickly and evenly is provided with a perforation on the inner side of the spiral. For some small-diameter corn, since the moisture content of small-diameter corn is relatively low, the required drying time is also relatively short. In this invention, small-diameter corn can pass directly through the inner side of the spiral, thereby reducing the drying time and path of small-diameter corn, avoiding over-drying of small-diameter corn, and further increasing the uniformity of moisture content after corn drying.

[0037] 4. In this invention, a corn drying system that can dry corn quickly and evenly, the spiral strip can also be slidably connected to the upper grid and the spiral strip can be fixedly connected to the upper rotating ring to maintain synchronous movement. When the upper rotating ring and the spiral strip rotate, they force the corn to slide on the inner diameter of the spiral strip, preventing the corn from getting clogged due to excessive friction on the inner diameter of the spiral strip. Clogging can also be prevented by increasing the downward tilt of the upper grid.

[0038] 5. This corn drying system can dry corn quickly and evenly. Corn falling from the upper grid will fall onto the upper side of the lower grid, and then fall into the inner side of the discharge space through the discharge gap at the edge of the lower grid. The dried corn in the discharge space can be discharged by opening the discharge pipe.

[0039] 6. The present invention provides a corn drying system that can dry corn quickly and evenly. An inclined ring is fixedly connected to the inside of the pre-storage space. The inclined ring causes the corn in the pre-storage space to pass through and approach the preheating cone when it is fed, thereby ensuring the uniformity of preheating.

[0040] 7. The corn drying system capable of fast and uniform drying, in order to prevent the through hole on the upper rotating ring from being communicated with the discharging hole on the edge position of the preheating cone when the hot air with moisture enters into the pre-storing space through the gap between the through hole on the upper rotating ring and the discharging hole, the lower rotating ring synchronously rotating with the upper rotating ring is further arranged, the through hole on the lower rotating ring is staggered with the through hole on the upper rotating ring, and the storage cylinder is arranged between the upper rotating ring and the lower rotating ring, when the through hole on the upper rotating ring is communicated with the discharging hole on the edge position of the preheating cone, the corn enters into the inside of the storage cylinder, at this time, the through hole on the lower rotating ring is not communicated with the bottom end of the storage cylinder, namely, the bottom end of the storage cylinder is closed at this time, with the continuous rotation of the upper rotating ring and the lower rotating ring, when the through hole on the lower rotating ring is communicated with the bottom end of the storage cylinder, the through hole on the upper rotating ring will not be communicated with the top end of the storage cylinder, at this time, the corn in the storage cylinder is discharged, the storage cylinder plays a role of temporary storage, and the hot air with moisture is prevented from entering into the inside of the pre-storing space, and the drying effect on the corn is further ensured.

[0041] 8. The corn drying system capable of fast and uniform drying, the preheating cone is a heat accumulating element, the heat accumulating element can be iron sheets arranged in an interval and stacked, which is used for temporarily storing heat energy and transferring the heat energy into the pre-storing space to realize preheating.
