Description

Technical Field

[0001] The utility model relates to the technical field of rice drying equipment, and particularly relates to an efficient rice dehydration and drying device. Background Art

[0002] Rice, a plant of the genus Oryza in the family Poaceae, also known as paddy, is one of the important food crops for humans. Rice is not only an important food source for humans but also has a profound impact on human society in various aspects such as society, economy, culture, and politics. With the development of technology and the global emphasis on sustainable development, the cultivation and utilization of rice will play a more important role in ensuring food security and promoting an environment-friendly society.

[0003] At present, when the existing rice drying equipment is in use, it is necessary for workers to put the rice into the drying box for drying. The rice is stacked on the drying tray. Since the stacking thickness of the rice at different positions is different, the drying speed of the rice at different positions is different, thus affecting the overall drying efficiency of the rice.

[0024] Please refer to Figures 1-3, the utility model provides a high-efficiency rice dehydration and drying device, including a drying box 1. One side of the outer wall of the drying box 1 is fixedly connected with a first motor 2. The driving shaft of the first motor 2 penetrates through the drying box 1 and is fixedly connected with a connecting frame 3. The middle part of the connecting frame 3 is fixedly connected with a central frame 4. Side frames 5 are arranged at both the top and bottom of the connecting frame 3. Both sides of the central frame 4 and the side frames 5 are smoothly attached to the inner wall of the drying box 1. By driving the central frame 4 and the side frames 5 to rotate through the first motor 2, the two can be flipped. When set in a vertical state, rice can fall and be discharged from the bottom ends of the two.

[0025] Wire meshes 6 are embedded and fixedly connected at the centers of the central frame 4 and the side frames 5. Among them, rectangular grooves corresponding to the wire meshes 6 are opened inside the central frame 4 and the two side frames 5. The distance between the top of the wire mesh 6 and the top plane of the rectangular groove is one centimeter, and the thickness of the rice that can be accommodated is also about one centimeter. After the rice is flattened, it is convenient for the drying warm air to better contact the rice, greatly reducing the drying effect of some rice affected by the accumulation of rice.

[0026] One side of the central frame 4 is fixedly connected with a second motor 7. The driving shaft of the second motor 7 is fixedly connected with a threaded rod 8. A sliding seat 9 is threadedly connected to the outer side wall of the threaded rod 8. Connecting plates 10 are fixedly connected to both the top and bottom of the sliding seat 9. One side of the connecting plate 10 is fixedly connected with a scraper 11.

[0027] Among them, the sliding seat 9 is slidably connected to the outer wall of the central frame 4. There are three scrapers 11. The three scrapers 11 are respectively located at the tops of the central frame 4 and the two side frames 5. By scraping the tops of the central frame 4 and the two side frames 5 with the scraper 11, it is convenient to flatten the rice to be dried.

[0028] A warm air blower 12 is fixedly connected to the outer side wall of the drying box 1 near the bottom. The warm air outlet of the warm air blower 12 penetrates through the drying box 1 and is connected to its interior. There are two warm air blowers 12. The two warm air blowers 12 are respectively located on both sides of the outer wall of the drying box 1. By providing drying hot air through the two warm air blowers 12 on both sides, it is convenient to dry the rice in the drying box 1. The hot air rises, which is convenient to take away the moisture.

[0029] A pressure relief plate 13 is arranged at the pressure relief port at the top of the drying box 1. An absorbent filter element 19 is arranged on the inner wall of the pressure relief port at the top of the drying box 1. Wing plates 14 are fixedly connected to both sides of the top of the drying box 1. A spring group 15 is fixedly connected between the wing plates 14 and the pressure relief plate 13. When the air pressure in the drying box 1 is too high, the gas can be discharged through the pressure relief plate 13 to balance the air pressure.

[0030] A discharge door 16 is provided at the bottom of the drying oven 1. An access door 17 is provided on the side of the drying oven 1 away from the first motor 2. Both sides of the outer wall of the drying oven 1 are fixedly connected with a pump body 18. The air suction end of the pump body 18 penetrates through the top of the drying oven 1 and is connected to its interior. The air exhaust end of the pump body 18 penetrates through the drying oven 1 and the exhaust port is located at the bottom of the side frame 5. Before the hot air is discharged, part of the hot air can be re-pumped into the drying oven 1 by the pump body 18 and sprayed onto the rice at an accelerated speed, which is convenient for recovering the hot air and improving the drying efficiency of the rice.

[0031] During use, first connect the first motor 2, the warm air blower 12 and the pump body 18 to an external power supply. The second motor 7 is equipped with a battery for easy power supply. Open the access door 17 and spread the rice to be dried on the tops of the central frame 4 and the side frame 5.

[0032] Start the second motor 7 to drive the threaded rod 8 to rotate, drive the sliding seat 9 to move on one side of the central frame 4, and synchronously drive the three scraping plates 11 to scrape on the tops of the central frame 4 and the side frame 5, which is convenient for leveling the rice on the wire mesh 6, making the rice on the wire mesh 6 more flat and uniform, and filling the space between the wire mesh 6 and the rectangular groove.

[0033] Subsequently, start the warm air blower 12 to introduce warm air at about 40 °C into the drying oven 1, and dry the rice in the central frame 4 and the side frame 5 from bottom to top. The hot air rises and is discharged through the pressure relief plate 13. At the same time, during the drying process, start the pump body 18 to re-pump part of the hot air into the drying oven 1 from the pressure relief port and accelerate it to spray onto the central frame 4 and the side frame 5, so that the hot air circulates and the utilization rate is improved.

[0034] When the drying is completed, start the first motor 2 to drive the connecting frame 3 to rotate, and then drive the central frame 4 and the side frame 5 to rotate from the horizontal state to the vertical state. At this time, under the action of gravity, the rice falls from the wire mesh 6 and is quickly discharged through the discharge door 16 at the bottom of the drying oven 1, eliminating the need for manual material collection by workers and greatly improving the discharging efficiency of the rice.

[0035] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention.
