Technical Field
[0001] This application relates to the technical field of rice seed drying equipment, and in particular to a rapid drying device for rice seeds. Background Technology
[0002] Drying rice seeds is a crucial step in seed storage, processing, and breeding. Rapid drying devices can efficiently remove moisture while preserving seed viability, preventing mold or germination. A patent document with authorization publication number CN220793659U discloses a rice seed drying device, including a shell and a drying mechanism. The top of the shell has a slotted feed hopper, and the outer side of the shell has a slotted discharge plate. The drying mechanism is located inside the shell. During operation, heating wires installed on the inner wall of the shell heat the interior, thereby drying the rice seeds. Power generated by a drive motor is transmitted through a gearbox to a drive shaft, rotating blades to ensure even heating of the rice seeds during drying. Air inlets and exhaust fans are installed on both sides of the shell, and the air duct design ensures smooth airflow, effectively removing moisture from the surface of the rice seeds. Temperature and humidity sensors accurately detect temperature and humidity, and a controller prevents temperature and humidity fluctuations during the drying process, ensuring the drying effect and quality of the rice seeds.
[0003] The above-mentioned solution still has at least the following shortcomings in actual use: In the process of drying rice seeds, there is a lack of effective impurity screening function. Since rice seeds are often mixed with unqualified rice seeds (shriveled and broken rice seeds) and dust particles, in order to ensure the cleanliness and quality of rice seeds, an additional cleaning process is required after drying, which increases processing costs and time.
[0004] Therefore, we propose a rapid drying device for rice seeds to solve the above problems. Utility Model Content
[0005] The purpose of this application is to provide a rapid drying device for rice seeds, which can perform uniform and comprehensive heating and drying treatment on rice seeds. Moreover, during the drying process, it can comprehensively and efficiently remove unqualified rice seeds and dust particles from the rice seeds, effectively improving the drying efficiency of rice seeds and enhancing the cleanliness and quality of the rice seeds.
[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a rapid drying device for rice seeds, comprising a support base and a heat insulation cylinder fixedly mounted on the top of the support base. Rotary shafts are rotatably mounted on both sides of the heat insulation cylinder, with one end of each shaft extending into the heat insulation cylinder.

[0036] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0037] See Figures 1-5This application provides a rapid drying device for rice seeds, including a support base 1 and a heat insulation cylinder 2 fixedly mounted on the top of the support base 1. Rotating shafts 3 are rotatably mounted on both sides of the heat insulation cylinder 2, with one end of each shaft 3 extending into the heat insulation cylinder 2. A mesh-shaped drying cylinder 4 is fixedly mounted on the same end of each shaft 3. The mesh-shaped drying cylinder 4 is used to hold rice seeds. The aperture size of the mesh-shaped drying cylinder 4 is smaller than the particle size of qualified rice seeds, thus preventing qualified rice seeds from leaking out of the mesh-shaped drying cylinder 4 and preventing unqualified seeds from leaking out. Rice seeds and dust particles can pass through the aperture of the mesh-shaped drying cylinder 4 and escape. An electric heating plate 5 is fixedly installed on the inner top wall of the heat insulation cylinder 2. A motor 23 is fixedly installed on the outer right side wall of the heat insulation cylinder 2 via a bracket. The output shaft of the motor 23 is fixedly connected to the right end of the rotating shaft 3 located on the right side. Driven by the motor 23, the mesh-shaped drying cylinder 4 rotates, causing the rice seeds inside the mesh-shaped drying cylinder 4 to turn evenly. At the same time, combined with the heat radiation from the top electric heating plate 5, the heating area of the rice seeds can be greatly increased, and the drying can be fully and evenly distributed. The heating and drying process enables uniform evaporation of moisture in a short time, effectively protecting the activity of rice seeds, reducing the risk of germination damage, and improving drying efficiency. A dust collection box 6 is fixedly installed on the support base 1, located below the heat insulation cylinder 2. An air pump 7 is fixedly installed on the left outer wall of the dust collection box 6. A dust filter 8 is fixedly installed inside the dust collection box 6. An air suction pipe 9 is fixedly connected to the suction end of the air pump 7. One end of the air suction pipe 9 extends into the dust collection box 6 and is located to the left of the dust filter 8. A dust suction pipe 10 is fixedly installed on the top of the dust collection box 6, and the bottom end of the dust suction pipe 10 extends into the dust collection box 6. Located to the right of the dust filter 8, the top of the suction pipe 10 extends into the heat insulation cylinder 2. The air pump 7 can extract the air from the dust collection box 6 through the suction pipe 9, creating a negative pressure inside the dust collection box 6. Then, the suction pipe 10 sucks the unqualified rice seeds and dust particles from the heat insulation cylinder 2 into the dust collection box 6. The dust filter 8 can intercept and filter the unqualified rice seeds and dust particles, keeping them inside the dust collection box 6. This achieves both maintaining a clean drying environment and improving the cleanliness and quality of the rice seeds.
[0038] In this embodiment, an air dehumidifier 11 is fixedly installed on the left outer wall of the heat insulation cylinder 2. An air inlet pipe 12 is fixedly connected to the air inlet end of the air dehumidifier 11. One end of the air inlet pipe 12 is fixedly connected to the discharge end of the air pump 7. A return pipe 13 is fixedly connected to the air outlet end of the air dehumidifier 11. One end of the return pipe 13 extends into the heat insulation cylinder 2. The air dehumidifier 11 is used to dehumidify and dry the air entering it. The return pipe 13 is used to transport the dried air back to the heat insulation cylinder 2, forming a closed loop system. This design can not only reduce heat loss and energy consumption, but also continuously maintain a low humidity environment inside the heat insulation cylinder 2, accelerate the evaporation of water from rice seeds, and further improve drying efficiency.
[0039] In this embodiment, the diameter of the grid-shaped drying cylinder 4 gradually decreases from the middle to both sides, so that all the dried rice seeds can be discharged from the grid-shaped drying cylinder 4.
[0040] In this embodiment, a feeding hole is provided at the center of the top of the heat insulation cylinder 2, and an upper sealing plug 14 is installed in the threaded part of the feeding hole. A discharge hole is provided at the center of the bottom of the mesh drying cylinder 4, and a lower sealing plug 15 is installed in the threaded part of the discharge hole. An inlet and outlet pipe 16 is fixedly connected to the center of the top of the mesh drying cylinder 4. An end cap 17 is installed at the top of the inlet and outlet pipe 16, which facilitates the pouring of rice seeds into the mesh drying cylinder 4 and the discharge of the dried rice seeds from the mesh drying cylinder 4.
[0041] In this embodiment, the diameter of the end cap 17 is smaller than the inner diameter of the discharge hole. The inner diameter of the discharge hole is the same as the inner diameter of the feeding hole, so as to facilitate removing the end cap 17 from the heat insulation cylinder 2 and to facilitate reinstalling the end cap 17 on the inlet and outlet pipes 16.
[0042] In this embodiment, two symmetrically arranged annular seats 18 are fixedly installed inside the heat insulation cylinder 2. Annular guide grooves 19 are provided on the inner ring walls of the two annular seats 18. Multiple guide blocks 20 are fixedly installed on the outer wall of the mesh drying cylinder 4. The multiple guide blocks 20 are arranged in two rows with equal spacing in annular distribution. The multiple guide blocks 20 are slidably installed in the corresponding annular guide grooves 19, which can ensure the stability of the mesh drying cylinder 4 during rotation.
[0043] In this embodiment, high-temperature resistant elastic rubber rods 21 are fixedly installed on the inner walls of both sides of the heat insulation cylinder 2. High-temperature resistant elastic rubber balls 22 are fixedly installed at the ends of the two high-temperature resistant elastic rubber rods 21 that are close to each other. The side of the high-temperature resistant elastic rubber balls 22 away from the high-temperature resistant elastic rubber rods 21 extends into the annular seat 18 and is located between two adjacent guide blocks 20. The vibration force generated by the intermittent collision between the high-temperature resistant elastic rubber balls 22 and the guide blocks 20 can be transmitted to the grid-shaped drying cylinder 4, which can improve the screening efficiency and screening effect of unqualified rice seeds and dust particles in rice seeds, and further improve the quality of rice seeds.
[0044] In this embodiment, the high-temperature resistant elastic rubber rod 21 and the high-temperature resistant elastic rubber ball 22 are integrally molded, which can enhance the reliability of the connection between the high-temperature resistant elastic rubber rod 21 and the high-temperature resistant elastic rubber ball 22.
[0045] In this embodiment, an indicator arrow 24 is fixedly installed on the left end of the rotating shaft 3 located on the left side. The direction of the indicator arrow 24 makes it easy for the staff to determine the position of the inlet and outlet pipes 16. When the indicator arrow 24 points vertically upward, the inlet and outlet pipes 16 are at the top and aligned with the feeding hole. When the indicator arrow 24 points vertically downward, the inlet and outlet pipes 16 are at the bottom and aligned with the discharge hole.
[0046] In this embodiment, a cleaning port located to the right of the dust filter 8 is provided on the inner front wall of the dust collection box 6, and a sealing cover 25 is fixedly installed on the outer front wall of the dust collection box 6 by screws. The sealing cover 25 is adapted to the cleaning port so as to clean out the unqualified rice seeds and dust particles collected in the dust collection box 6.
[0047] In this embodiment, the electric heating plate 5 is a temperature-adjustable constant temperature electric heating plate. The electric heating plate 5, the air pump 7, the air dehumidifier 11 and the motor 23 can all be purchased on the market. Their wiring connection method and control method are mature technologies in this field and have been fully disclosed. Therefore, they will not be described in detail here.
[0048] Based on the above structure, the operating principle of the rapid drying device for rice seeds provided in this application is as follows:
[0049] First, the operator observes the indicator arrow 24 on the left rotating shaft 3 and controls the motor 23 to run. When the indicator arrow 24 rotates to a vertical position, the motor 23 is stopped. At this time, the inlet and outlet pipes 16 of the grid-shaped drying cylinder 4 are aligned with the feeding hole at the top of the heat insulation cylinder 2. The upper sealing plug 14 and the end cap 17 of the inlet and outlet pipe 16 are opened in sequence. The rice seeds to be dried can be poured into the grid-shaped drying cylinder 4 through the feeding hole and the inlet and outlet pipe 16. After feeding is completed, the end cap 17 and the upper sealing plug 14 are screwed back in sequence.
[0050] Then, the motor 23 is started and runs. The motor 23 drives the right rotating shaft 3 to rotate, which drives the mesh drying cylinder 4 to rotate synchronously. At the same time, the electric heating plate 5 is turned on to generate heat (adjusted to a suitable temperature according to the characteristics of the seeds). The heat generated creates a suitable high-temperature environment in the heat insulation cylinder 2. When the mesh drying cylinder 4 rotates, the rice seeds inside it are evenly turned over and fully contacted with the hot air. The heating area is greatly increased, so as to achieve rapid and uniform evaporation of moisture in the rice seeds and carry out the drying process.
[0051] During the drying process, the mesh-shaped drying cylinder 4's aperture design prevents qualified rice seeds from leaking out, while unqualified rice seeds (shriveled and broken rice seeds), dust particles, and impurities leak out through the mesh holes as the mesh-shaped drying cylinder 4 rotates. At the same time, the guide block 20 on the outer wall of the mesh-shaped drying cylinder 4 rotates along with it and intermittently collides with the high-temperature resistant elastic rubber ball 22. The vibration force generated by the collision is transmitted to the mesh-shaped drying cylinder 4, further causing unqualified rice seeds (shriveled and broken rice seeds), dust particles, and impurities to detach from the seeds and leak out, thereby improving the screening efficiency and effect of removing unqualified rice seeds and dust particles from the rice seeds.
[0052] During the rice seed drying process, the air pump 7 and the air dehumidifier 11 are started. The suction force generated by the air pump 7 is used to draw air from the dust collection box 6 through the suction pipe 9, creating a negative pressure in the dust collection box 6. Then, the unqualified rice seeds (shriveled and broken rice seeds), dust particles and impurities in the heat insulation cylinder 2 are sucked into the dust collection box 6 through the dust suction pipe 10. These impurities are intercepted by the dust filter 8 and retained in the box. The air discharged by the air pump 7 enters the air dehumidifier 11 through the air inlet pipe 12. After being dehumidified and dried, it is sent back to the heat insulation cylinder 2 through the return air pipe 13, thus forming a closed circulation of air. This process not only recovers heat and reduces energy consumption, but also maintains a low humidity environment in the heat insulation cylinder 2, accelerates the evaporation of moisture from the rice seeds, and improves the drying efficiency of the rice seeds.
[0053] After drying is completed, stop the operation of the air pump 7 and the air dehumidifier 11, turn off the electric heating plate 5, and when the indicator arrow 24 points vertically downward, turn off the motor 23. At this time, the inlet and outlet pipes 16 are aligned with the discharge hole. Then, unscrew the lower sealing plug 15 of the discharge hole and the end cap 17 of the inlet and outlet pipes 16. The qualified rice seeds dried inside the grid-shaped drying cylinder 4 are all discharged outside the heat insulation cylinder 2 under the action of gravity.
