Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of seed drying equipment, specifically a drying device for large-diameter seeds. Background Technology
[0002] Seed drying primarily aims to reduce seed moisture content, facilitating long-term storage and maintaining seed viability. Excessive seed moisture content can lead to increased respiration, depleting nutrient reserves and potentially causing mold, pests, and other problems, negatively impacting germination rate and quality. Appropriately reducing seed moisture content through drying inhibits seed metabolism, inducing dormancy, reducing nutrient consumption, and extending seed lifespan—a crucial technology for modern agricultural enterprises. In practice, for large-diameter, shelled seeds such as sunflowers, pumpkins, and zucchini, the drying temperature should not be too high, ideally around 40-50℃. Furthermore, because the seed coat is more easily broken, turning or other actions during drying should be avoided. Therefore, a drying device suitable for large-diameter seeds needs to be developed. Utility Model Content
[0003] To address the above technical problems, this utility model provides a drying device for large-diameter seeds.
[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a drying device for large-diameter seeds, including a drying trough and a hot air furnace, and a mixing chamber. The hot air furnace is connected to the mixing chamber through a hot air pipe, and the mixing chamber is connected to the drying trough through a mixing pipe. A horizontal pipe is connected to the end of the mixing pipe, and multiple heat dissipation pipes are connected to the horizontal pipe. Several air holes are opened on the heat dissipation pipes, and the heat dissipation pipes are fixedly connected to the inside of the drying trough. A cold air pipe is also connected to the mixing chamber. A conveyor is rotatably connected inside the drying trough. The conveyor is a breathable conveyor belt. The heat dissipation pipes are located in the middle of the conveyor. A discharge port is fixedly connected to the front of the drying trough. A baffle plate is fixedly connected inside the drying trough, and a through hole is spaced between the baffle plate and the upper surface of the conveyor.
[0005] Furthermore, the control motor of the conveyor is fixedly connected to the drying tank.
[0006] Furthermore, a support roller is rotatably connected inside the drying tank, the support roller supports the conveyor, and the heat dissipation pipe is located between two adjacent support rollers.
[0007] Furthermore, a first fan is installed on the hot air duct, a second fan is installed on the cold air duct, and a third fan is installed on the heat mixing duct.
[0008] Furthermore, a baffle is movably connected to the first end of the discharge port.

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] like Figures 1-2The drying device for large-diameter seeds shown includes a drying trough 1 and a hot air furnace 15, wherein the hot air furnace 15 is either an electric hot air furnace or a fuel-fired hot air furnace. It also includes a mixing chamber 9. The hot air furnace 15 is connected to the mixing chamber 9 via a hot air pipe 13. The mixing chamber 9 is connected to the drying trough 1 via a mixing pipe 7. A horizontal pipe 6 is connected to the end of the mixing pipe 7. The horizontal pipe 6 is fixedly connected to the side plate of the drying trough 1 using clips. Multiple heat dissipation pipes 18 are connected to the horizontal pipe 6, and each heat dissipation pipe 18 has several air holes. The heat dissipation pipes 18 are fixedly connected... Inside the drying trough 1, a cold air duct 10 is connected to the mixing box 9. The end of the cold air duct 10 is located outside the working room wall. A conveyor 3 is rotatably connected inside the drying trough 1. Flat plates are fixedly connected to the drying trough 1 at both ends of the conveyor 3. The conveyor 3 is a breathable conveyor belt. A heat dissipation pipe 18 is located in the middle of the conveyor 3. A discharge port 2 is fixedly connected to the front of the drying trough 1. A baffle plate 5 is fixedly connected inside the drying trough 1. There are through holes between the baffle plate 5 and the upper surface of the conveyor 3. The height of the through holes is 3-7cm.
[0019] To facilitate control and transmission, the control motor 16 of the transmission machine 3 is fixedly connected to the drying tank 1. Based on the configuration of the transmission machine 3, the control motor 16 can be either an external motor or an internal motor.
[0020] To facilitate the support of the conveyor 3, a support roller 17 is rotatably connected inside the drying tank 1. The support roller 17 supports the conveyor 3, and the heat dissipation pipe 18 is located between two adjacent support rollers 17.
[0021] To facilitate airflow, a first fan 14 is installed on the hot air duct 13, a second fan 11 is installed on the cold air duct 10, and a third fan 8 is installed on the heat mixing duct 7.
[0022] To prevent seeds from leaking out, a baffle 4 is movably connected to the first end of the discharge port 2. The discharge port 2 is tilted downward and narrows towards the middle. There is a groove at the first end of the discharge port 2, which is engaged with the baffle 4.
[0023] To control the air temperature, a first temperature probe is installed inside the hot air duct 13, and a second temperature probe is installed inside the mixing chamber 9.
[0024] To prevent the intake of impurities, a filter screen 12 is fixedly connected to the air inlet end of the cold air duct 10.
[0025] The specific working process of this utility model is as follows:
[0026] During operation, baffle 4 is placed at the beginning of the discharge port 2, and seeds are poured into one end of the drying trough 1. At the same time, the control motor 16 is turned on to rotate, and the rotation of the conveyor 3 is used to spread the seeds evenly. During this process, baffle 5 blocks the seeds so that they can be spread evenly. At this time, the hot air furnace 15 is turned on, and hot air enters the mixing chamber 9 from the hot air pipe 13. During this process, the first fan 14 is turned on, and the first temperature probe monitors the temperature inside the hot air pipe 13. If the temperature is within 40-50℃, the third fan 8 is turned on. The hot air is accelerated by the third fan 8, enters the horizontal pipe 6 from the mixing pipe 7, and is then blown out from the air hole on the heat dissipation pipe 18 to dry the seeds. When the first temperature probe detects that the temperature inside the hot air pipe 13 is higher than 50℃, the second fan 11 is turned on to draw in cold air from the outside and mix the hot air temperature in the mixing chamber 9 to about 45℃ before drying the seeds.
[0027] When removing the seeds, remove the baffle 4, turn on the control motor 16, drive the conveyor 3 to rotate, and discharge the seeds from the outlet 2.
