Description

Technical Field

[0001] This utility model relates to the field of rice drying technology, specifically a rice drying device with an upper and lower turning mechanism. Background Technology

[0002] Drying is a crucial step in the post-harvest processing of rice. Traditional rice drying methods often have many shortcomings. For example, some simple sun-drying methods are severely limited by weather conditions. If it rains, the rice is prone to mold and spoilage, leading to a decline in quality and economic losses.

[0003] However, some existing drying equipment tends to cause rice to pile up during the drying process, making it difficult for the rice inside to fully contact the hot air, resulting in uneven drying. This leads to some rice being over-dried while others are under-dried, affecting the overall drying quality. At the same time, the feeding and turning methods of traditional drying equipment are not efficient enough, making it difficult to ensure stable drying efficiency and good drying effect, and thus failing to meet the needs of large-scale rice drying.

[0004] Therefore, this utility model provides a rice drying device with top and bottom turning to solve the above problems. Utility Model Content

[0012] Beneficial effects

[0013] This invention provides a rice drying device with an upper and lower turning mechanism. Compared with the prior art, it has the following advantages:

[0014] 1. This rice drying device with top and bottom turning features a mesh cylinder with spiral blades inside the drying drum. Combined with an air inlet pipe, an air outlet pipe, and an air pump, it enables hot air to flow effectively inside the mesh cylinder. The spiral blades continuously transport the rice from left to right. As the mesh cylinder rotates, the rice rises due to friction and then falls back down, achieving a top and bottom turning effect. This greatly increases the contact area and contact time between the rice and the hot air, ensuring drying efficiency and quickly removing moisture from the rice, thus meeting the needs of large-scale rice drying operations.

[0015] 2. This rice drying device with top and bottom turning mechanism effectively avoids the accumulation of rice during the drying process by turning the rice inside the mesh cylinder and conveying it with spiral blades. This ensures that each grain of rice is evenly exposed to hot air, thereby ensuring the uniformity of drying, reducing the quality differences of rice caused by uneven drying, and improving the overall drying quality.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides a rice drying device with top and bottom turning mechanism, including a base plate 1. A drying assembly 2 and a conveying assembly 3 are disposed on the top of the base plate 1. The drying assembly 2 includes a drying cylinder 21. A second cylinder 27 and a first cylinder 26 are rotatably connected to the left and right ends of the drying cylinder 21. A mesh cylinder 28 is fixedly installed between the second cylinder 27 and the first cylinder 26, inside the drying cylinder 21. Spiral blades 29 are fixedly installed inside the mesh cylinder 28. An air inlet pipe 22 is fixedly installed at the bottom of the drying cylinder 21, and an air outlet pipe 23 is fixedly installed at the top of the drying cylinder 21. The air inlet pipe 22 is fixedly installed at the lower left of the drying cylinder 21 and communicates with the interior of the drying cylinder 21. The air outlet pipe 23 is fixedly installed at the upper right of the drying cylinder 21 and communicates with the interior of the drying cylinder 21. An air pump 24 is fixedly installed between the air outlet pipes 23.

[0025] A bracket 25 is fixedly installed at the bottom of the drying cylinder 21, and the bracket 25 is fixedly installed on the top of the base plate 1. The left side of the drying cylinder 21 is higher than the right side. A gear ring 210 is fixedly installed on the outer side of the second cylinder 27, and a first motor 212 is fixedly installed on the top of the drying cylinder 21. A gear 211 is fixedly installed at the output end of the first motor 212, and the gear 211 meshes with the gear ring 210.

[0026] In this embodiment, when drying rice, the rice is fed into the mesh cylinder 28 through the second cylinder 27. The drying hot air enters through the air inlet pipe 22, and after entering, it is absorbed by the air pump 24 and discharged through the air outlet pipe 23, thereby realizing the flow of hot air inside the mesh cylinder 28. The first motor 212 is started to drive the gear 211 to rotate. The rotation of the gear 211 drives the gear ring 210 to rotate, and the rotation of the gear ring 210 drives the second cylinder 27 to rotate, thereby driving the mesh cylinder 28 to rotate. When the mesh cylinder 28 rotates, the internal spiral blades 29 can move the rice inside the mesh cylinder 28 from left to right. During the movement, the rice rises along the side of the mesh cylinder 28 under the friction force, and falls under the action of gravity after rising to a certain height, thereby realizing the up-and-down tumbling of the rice. During the tumbling, the hot air blows through to take away the moisture inside the rice, thus achieving drying. The spiral blades 29 continuously transport the rice and continuously dry it, ensuring drying efficiency. The up-and-down tumbling of the rice makes the drying effect better.

[0027] Reference Figures 1 to 4 In one aspect of this embodiment, the conveying assembly 3 includes a spiral conveying cylinder 31, a discharge hopper 32 is fixedly installed on the side of the spiral conveying cylinder 31, the right end of the discharge hopper 32 is located inside the second cylinder 27, and a support frame 33 is fixedly installed at the bottom of the spiral conveying cylinder 31, and the support frame 33 is fixedly installed on the top of the base plate 1.

[0028] A feeding hopper 35 is fixedly installed on the left side of the spiral conveyor cylinder 31. Both the feeding hopper 35 and the discharge hopper 32 are connected to the inside of the spiral conveyor cylinder 31. A second motor 34 is fixedly installed at the bottom of the support frame 33. A spiral conveying rod is fixedly installed inside the spiral conveyor cylinder 31. The output end of the second motor 34 movably passes through the support frame 33 and the bottom wall of the spiral conveyor cylinder 31 and is fixedly connected to the spiral conveying rod.

[0029] In this embodiment, during the drying process, rice is placed inside the feeding hopper 35. The second motor 34 is started to drive the internal spiral conveyor to rotate. The spiral conveyor can transport the rice inside the feeding hopper 35 upwards. After being transported to the top, it is discharged through the discharge hopper 32. The discharge hopper 32 continuously supplies material, and the feeding rate of rice is adjusted by the rotation speed of the second motor 34, thereby ensuring the drying effect.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: During rice drying, the rice is fed into the mesh cylinder 28 through the second cylinder 27. Hot air enters through the air inlet pipe 22 and, after being absorbed by the air pump 24, is discharged through the air outlet pipe 23, thus achieving hot air flow inside the mesh cylinder 28. Starting the first motor 212 drives the gear 211 to rotate, which in turn drives the gear ring 210, which in turn drives the second cylinder 27, thereby rotating the mesh cylinder 28. As the mesh cylinder 28 rotates, the internal spiral blades 29 move the rice from left to right along the side of the mesh cylinder 28. During this movement, the rice rises along the side of the mesh cylinder 28 due to friction. After rising to a certain height, the rice falls under the influence of gravity, thus achieving the vertical rotation of the rice. During rotation, hot air blows through the rice to remove the internal moisture, achieving drying. The rice is continuously conveyed and dried by the spiral blades 29, ensuring drying efficiency. The vertical rotation of the rice improves the drying effect. When feeding the rice, it is placed inside the feeding hopper 35. The second motor 34 is started to drive the internal spiral conveyor to rotate. The spiral conveyor can convey the rice inside the feeding hopper 35 upwards. After being conveyed to the top, it is discharged through the discharge hopper 32. The discharge hopper 32 continuously conveys the rice, and the feeding rate of the rice is adjusted by the rotation speed of the second motor 34, thereby ensuring the drying effect.
