Description

Far infrared grain drying device

The present invention is a far-infrared grain drying device, more specifically, a design in which a far-infrared rice husk furnace is installed in the grain drying part. In addition to utilizing waste rice husks as fuel to generate far-infrared heat energy by burning the far-infrared rice husk furnace, the far-infrared heat energy generated by the far-infrared rice husk furnace can be further used for drying grains, thereby achieving the effect of recycling waste and killing two birds with one stone.

The traditional rice drying method usually involves sending wet grains into the top of a drying chamber, letting the wet grains fall from the top of the drying chamber, and then introducing hot air from the hot air source into the drying chamber, using the hot air to blow towards the wet grains for drying until the wet grains are completely dried. The hot air blown out of the drying chamber causes the wet grains to be constantly exposed to the high-temperature hot air and continuously baked at high temperatures, which can easily cause the wet grains to crack during the drying process, that is, the wet grains burst, affecting the quality of the grains after drying.

In addition, the main improvement direction of the industry is usually aimed at the heat exchange drying method of hot air and wet grains, that is, to improve the direction of hot air flow and the direction of grain movement. According to the difference between the direction of hot air flow and the direction of grain movement, it can be roughly divided into four categories: the first is cross flow, which is a drying operation for grains when the direction of hot air flow and the direction of grain movement are perpendicular to each other. The second is counter flow, which is a drying operation for grains when the direction of hot air flow and the direction of grain movement are parallel to each other and the two move in opposite directions. The third is concurrent flow, which is a drying operation for grains when the direction of hot air flow and the direction of grain movement are parallel to each other and the two move forward synchronously. The fourth is mixed flow, which is a drying operation for grains in which the direction of the dry hot air flow is partly forward and partly reverse to the direction of grain movement. Regardless of which method is used, wet grains are usually prone to cracking during the drying process, that is, wet grains burst, which affects the quality of the grains after drying. Therefore, in practice, there is still room for continuous improvement in how to avoid grain cracking and improve grain drying quality.

This invention is a new invention mainly aimed at the shortcomings of the above-mentioned known grain drying equipment.

Under the double baking effect, the drying efficiency of the grains is accelerated, and the disadvantage of drying the grains purely with hot air, which is easy to cause over-drying and cracking of the grains, is avoided, thereby improving the quality of grain drying.

Another purpose of the present invention is a far infrared grain drying device, which utilizes a rice husk inlet, a combustion-supporting fan, a bellows, an ash discharge hole, an observation hole, a waste heat discharge hole, and a heat sink, and cooperates with the design of a first screen, a first guide plate, a second screen, a second guide plate, a grain discharge mechanism, an air inlet, an air outlet, and a suction device, so that the far infrared rice husk furnace can operate stably and efficiently, thereby improving the drying efficiency.

The invention discloses a far infrared grain drying device, please refer to FIG1 and FIG2 at the same time; FIG1 is a cross-sectional schematic diagram of the far infrared grain drying device; FIG2 is a three-dimensional schematic diagram of a far infrared rice husk furnace of the far infrared grain drying device. The far infrared grain drying device comprises: a far infrared rice husk furnace 10, a grain drying part 20, a rice husk hopper device 30, a grain lifting mechanism 40, and a grain scattering mechanism 50. The far infrared rice husk furnace 10 is provided with a rice husk inlet 11, a combustion-supporting fan 12, a wind box 13, an ash discharge hole 14, an observation hole 15, a waste heat discharge hole 16, and a heat sink 17. The rice husk inlet 11 is arranged at a predetermined position below the first surface 18 of the furnace body of the far infrared rice husk furnace 10, and serves as an inlet for rice husk or other biomass particles. By burning rice husk or biomass particles, the far infrared rice husk furnace 10 generates heat energy. The combustion-supporting fan 12 is arranged at a predetermined position below the far-infrared rice husk furnace 10, and its air outlet is connected to the wind box 13 through a pipeline penetrating the bottom of the grain drying part 20, and the combustion-supporting fan 12 is used to provide positive pressure wind force in the far-infrared rice husk furnace 10. The wind box 13 is arranged at the bottom of the far-infrared rice husk furnace 10 perpendicular to the first surface 18 of the furnace body, and is connected to the air outlet of the combustion-supporting fan 12. The wind box 13 provides a buffer between the positive pressure of the combustion-supporting fan 12 and the negative pressure of the suction force of the waste heat discharge hole 16, so as to avoid the combustion ash flying caused by the positive and negative pressures inside the far-infrared rice husk furnace 10. The ash discharge hole 14 is arranged at a predetermined position at the rear end of the bottom of the far infrared rice husk furnace 10 at the same position as the bellows 13, and is used to discharge the ash after the rice husk or other biomass particles are burned in the far infrared rice husk furnace 10. The ash discharge hole 14 extends from the far infrared rice husk furnace 10 to the bottom outer side of the grain drying part 20. The operator can collect the ash after the rice husk or biomass particles are burned through the ash discharge hole 14 to prevent the ash from flying everywhere and polluting the environment. The observation hole 15 is disposed at a predetermined position below the second surface 19 of the far infrared rice husk furnace 10. The second surface 19 of the furnace body is parallel to the first surface 18 of the furnace body, and both are perpendicular to the bottom of the far infrared rice husk furnace 10. The far infrared rice husk furnace 10 of this embodiment is illustrated by an octahedron, but it is not used to limit the present invention. Other geometric shapes, such as a hexahedron, a dodecahedron, etc., are also within the scope of the present invention. The observation hole 15 extends from the far infrared rice husk furnace 10 to the outer back side of the grain drying part 20. The operator can monitor the combustion status inside the far infrared rice husk furnace 10 through the observation hole 15, replenish rice husks or biomass particles in time, or properly adjust the positive and negative pressure inside the far infrared rice husk furnace 10, so as to make the far infrared rice husk furnace 10 produce the best combustion effect. The waste heat discharge hole 16 is set at a predetermined position above the second surface 19 of the furnace body of the far infrared rice husk furnace 10, located above the observation hole 15, and on the same surface of the far infrared rice husk furnace 10 as the observation hole 15. The waste heat discharge hole 16 extends from the far infrared rice husk furnace 10 to the outside of the grain drying part 20, and a suction mechanism (not shown) may be optionally provided to discharge the waste heat after combustion from the far infrared rice husk furnace 10. In addition, a spark destroyer 80 may be optionally provided behind the waste heat discharge hole 16. Sparks are often sucked out of the far infrared rice husk furnace 10 from the waste heat discharge hole 16, causing fire or other disasters at the rear. The spark destroyer 80 can be used to collect and destroy the sparks to prevent the occurrence of disasters. The heat sink 17 is disposed on the outer surface of the far infrared rice husk furnace 10. The heat sink 17 is disposed on all surfaces except the first and second surfaces 18 and 19 of the furnace body of the far infrared rice husk furnace 10 and the bottom perpendicular to the first and second surfaces 18 and 19 of the furnace body. The heat energy generated by the internal combustion of the far infrared rice husk furnace 10 is converted into far infrared rays by the heat sink 17, and radiates and conducts heat energy to all directions inside the grain drying part 20, thereby drying the grains.

The far infrared rice husk furnace 10 is placed at a predetermined position at the bottom of the grain drying part 20, and is further provided with a first screen 22, a first guide plate 21, a second screen 24, a second guide plate 23, a grain discharge mechanism 27, an air inlet 28, an air outlet 29, and a suction device 70. The far infrared rice husk furnace 10 is separated by the first screen 22 to prevent the grains in the grain drying part 20 from directly contacting the far infrared rice husk furnace 10. A first guide plate 21 is disposed above the first screen 22 to cover the far infrared rice husk oven 10. The first guide plate 21 is shaped like a roof and is tilted at a predetermined angle, and the angle is to avoid being perpendicular to the inner wall of the grain drying part 20. In addition to guiding the flow of grains, it can also prevent grains from falling into the space surrounded by the first screen 22 and prevent grains from directly contacting the far infrared rice husk oven 10. A second screen 24 is disposed at a predetermined distance from the first screen 22, and a second guide plate 23 is disposed above the second screen 24. One end of the second guide plate 23 is connected to the top of the second screen 24, and the other end is fixed to the inner wall of the grain drying part 20. The second guide plate 23 is tilted at a predetermined angle, which is sufficient to smoothly guide the flow of grains and avoid being perpendicular to the inner wall of the grain drying part 20. In addition to guiding the flow of grains, the second guide plate 23 can also prevent wet grains from falling directly without being baked by the far-infrared rice husk furnace 10. The space enclosed by the first and second screens 22 and 24 forms a far-infrared baking area 25 in the grain drying part 20, and the other space in the grain drying part 20 forms a baking homogenization area 26. The bottom of the first and second screens 22 and 24 are provided with a grain discharge mechanism 27 (e.g. a controllable valve mechanism) to discharge the grains dried to a predetermined degree in the grain drying section 20. The grain drying section 20 is used to receive wet grains and serves as a mechanism for drying the wet grains. The interior of the grain drying section 20 is divided into a far infrared baking area 25 and a baking homogenization area 26. The rice husk hopper device 30 is installed at one side of the bottom of the grain drying section 20, near a predetermined position of the rice husk inlet 11. The rice husk hopper device 30 is provided with a spiral conveying mechanism inside. The operator only needs to pour the rice husk or other biomass particles into the rice husk hopper device 30, and the spiral conveying mechanism can convey the rice husk to the rice husk inlet 11, and then convey the rice husk to the far infrared rice husk furnace 10 for combustion through the rice husk inlet 11. The grain lifting mechanism 40 is arranged at the side of the grain drying part 20, and can convey the grains or other grains to be dried to the top of the grain drying part 20, and then convey the grains to the grain scattering mechanism 50 through the conveying pipe. The grain scattering mechanism 50 is disposed at the top of the grain drying section 20. The grains transported by the grain lifting mechanism 40 are sprinkled down from the top of the grain drying section 20 by the grain scattering mechanism 50 to perform a drying operation.

Please refer to Figures 3 and 4 at the same time. Figure 3 is a partial three-dimensional schematic diagram of the air flow line of the far infrared grain drying device of the present invention; Figure 4 is a top view schematic diagram of the air flow line of the far infrared grain drying device of the present invention. An air inlet 28 is provided at a predetermined position of the front of the grain drying part 20 relative to the first surface 18 of the furnace body of the far infrared rice husk furnace 10, and an exhaust port 29 is provided at a predetermined position of the back of the grain drying part 20 relative to the second surface 19 of the furnace body of the far infrared rice husk furnace 10, and a suction device 70 is provided at the predetermined position of the exhaust port 29. Fresh air enters the far infrared rice husk furnace 10 in the grain drying section 20 through the air inlet 28, and is first preheated to hot air by the far infrared rice husk furnace 10. Then the hot air penetrates the first and second screens 22 and 24 to the left and right, and in addition to stirring the grains in the far infrared baking area 25 between the first and second screens 22 and 24, it also dries and heats the grains. Then the hot air is pumped by the suction device 70 of the exhaust port 29 and discharged through the exhaust port 29. Therefore, the wet grains in the far infrared baking area 25 between the first and second screens 22 and 24 are not only baked by far infrared rays, but also stirred and dried by hot air, so the drying efficiency of the grains can be accelerated.

Please refer to Figures 2, 4 and 5 at the same time. Figure 5 is a cross-sectional schematic diagram of the far infrared grain drying device of the present invention during operation. First, the operator pours rice husks or other biomass particles into the rice husk hopper device 30, and the spiral conveying mechanism (not shown) inside the rice husk hopper device 30 conveys them to the rice husk inlet 11, and then conveys them into the far infrared rice husk furnace 10 through the rice husk inlet 11 for combustion. The heat energy generated by the combustion heats the surface around the far infrared rice husk furnace 10 to form far infrared rays. At the same time, the heat sink 17 on the surface of the far infrared rice husk furnace 10 radiates the far infrared heat energy to all directions inside the grain drying part 20, transfers the heat energy, and dries the grains. The combustion-supporting fan 12 sends fresh air into the far infrared rice husk furnace 10 to help the combustion of rice husks or biomass particles. The suction mechanism (not shown) of the waste heat discharge hole 16 provides suction force to the far infrared rice husk furnace 10 to discharge the waste gas after combustion. The positive pressure provided by the combustion-supporting fan 12 and the negative pressure provided by the exhaust heat discharge hole 16 suction mechanism are likely to cause the combustion ash to fly due to the positive and negative pressures inside the far-infrared rice husk furnace 10. Therefore, by using the design of the wind box 13 connected to the air outlet of the combustion-supporting fan 12, a buffer between the positive and negative pressures inside the far-infrared rice husk furnace 10 can be provided to avoid the combustion ash flying caused by the positive and negative pressures inside the far-infrared rice husk furnace 10. The ash after burning inside the far infrared rice husk furnace 10 is discharged from the ash discharge hole 14. Since the ash discharge hole 14 extends from the far infrared rice husk furnace 10 to the bottom outer side of the grain drying part 20, the operator only needs to prepare an ash conveyor 60 at the bottom of the grain drying part 20 to collect and transport the burned ash, thereby preventing the ash from flying everywhere and polluting the environment. The operator can monitor the combustion status inside the far infrared rice husk furnace 10 through the observation hole 15, and replenish rice husks or biomass particles in time, or appropriately adjust the positive and negative pressures inside the far infrared rice husk furnace 10, so as to achieve the best combustion effect of the far infrared rice husk furnace 10. When the grains or other grains to be dried are transported to the top of the grain drying part 20 by the grain lifting mechanism 40, the grain scattering mechanism 50 sprinkles the grains from the top of the grain drying part 20, and the far infrared rice husk furnace 10 provides far infrared heat energy to dry the grains. Fresh air enters the far infrared rice husk furnace 10 in the grain drying section 20 through the air inlet 28, and is preheated by the far infrared rice husk furnace 10. Then, the hot air penetrates the first and second screens 22 and 24 to the left and right, stirring the grains in the far infrared baking area 25 between the first and second screens 22 and 24, and dries and heats the grains at the same time. Then, the hot air is extracted from the exhaust port 29 through the suction device 70, forming a smooth airflow line. Therefore, the wet grains in the far infrared baking area 25 between the first and second screens 22 and 24 are not only baked by the far infrared rays, but also stirred and dried by the hot air. Due to the double baking effect, the drying efficiency of the grains can be improved. The first and second screens 22 and 24 around the far infrared rice husk furnace 10 can restrain the wet grains in the far infrared baking area 25 to prevent the grains from falling into the far infrared rice husk furnace 10 or falling into other areas. If the grains are not dried to the predetermined degree, they are transported to the top of the grain drying section 20 by the grain lifting mechanism 40, and then sprinkled by the grain scattering mechanism 50, and the drying operation is repeated until the grains are dried to the predetermined degree.

In summary, the far-infrared grain drying device of the present invention, by means of the design of arranging a far-infrared rice husk furnace in the grain drying part, can not only utilize the waste rice husk as fuel to make the far-infrared rice husk furnace burn to generate far-infrared heat energy, but also further provide the far-infrared heat energy generated by the far-infrared rice husk furnace for drying grains, thereby achieving the effect of recycling waste and killing two birds with one stone, which is suitable for industrial utilization. In addition to being baked by far infrared rays, the wet grains in the far infrared baking area between the first and second screens of the present invention are also stirred and dried by hot air. Under the dual baking effect, the drying efficiency of the grains is improved, which is more effective than the conventional technology and is progressive. In addition, this invention has not been published before the application, and its novelty is beyond doubt. This invention complies with the provisions of the Patent Law, and an application for an invention patent is filed in accordance with the law. I pray that you will review it and grant it a patent. I am truly grateful for your kindness.
