[0019] Reference Figure 1 - Figure 2 A drying device for processing melon seeds, comprising a drying box 1, a feed pipe 2 and a discharge pipe 3 are fixedly installed on the top and bottom of the drying box 1 respectively, and a solenoid valve is arranged on the discharge pipe to control opening and closing, a drying plate 4 is fixedly arranged on both side walls inside the drying box 1, and an electric heating wire 5 is buried inside the drying plate 4, a fixing block 6 is fixedly arranged in the middle of the top of the drying box 1, and a cavity 7 is opened inside the fixing block 6, and a heat transfer component is arranged between one side of the drying plate 4 and the cavity 7, and the heat transfer component is used to transfer part of the hot air generated by the drying plate 4 to the cavity 7;

[0020] The bottom of the fixed block 6 is rotatably connected to a rotating tube 8 through a bearing, and one end of the rotating tube 8 is communicated with the cavity 7. A driving mechanism for driving the rotating tube 8 to rotate is provided on the outer wall of the drying box 1. The driving mechanism includes a motor fixed on the outer wall of the drying box 1, and a driving gear 16 is transmission-connected to the output shaft of the motor. A driven gear 17 is fixedly sleeved on the outer wall of the rotating tube 8, and the driven gear 17 is meshed with the driving gear 16.

[0021] A number of dispersing rods 9 are evenly fixed on the outer wall of the rotating tube 8. A number of first air outlet holes 10 are formed in the rotating tube 8. The number of dispersing rods 9 are all of hollow structure and communicate with the rotating tube 8. A number of second air outlet holes 18 are formed in each dispersing rod 9. Such a setting can further increase the contact area between the hot air and the melon seeds at different positions, so that all parts of the surface of the melon seeds can receive the same degree of heat, further optimizing the heat transfer and drying effect, and improving the efficiency and quality of melon seed processing.

[0022] The heat transfer assembly includes a plurality of air outlet pipes 11, an air inlet pipe 12, a connecting pipe 13, an air suction hood 14 and an air extraction fan 15. The air suction hood 14 is located on one side of the drying plate 4. The plurality of air outlet pipes 11 penetrate through the drying box 1 to the air suction hood 14. The other end of the air outlet pipe 11 communicates with the connecting pipe 13. The other end of the connecting pipe 13 is communicated with the air inlet end of the air extraction fan 15. One end of the air inlet pipe 12 is communicated with the air outlet end of the air extraction fan 15. The other end of the air inlet pipe 12 is communicated with the cavity 7. The air suction hood 14 is located on one side of the drying plate 4 and is used for collecting the hot air generated by the drying plate 4 and pumping the hot air into the cavity 7 through the air extraction fan 15. Through the design of the heat transfer assembly, the hot air can be effectively collected, extracted and reused, realizing the recycling and dispersion of heat, avoiding the situation of local overheating or overcooling, and ensuring that the melon seeds can be evenly dried.

[0023] A humidity sensor 19 is fixedly installed on the top of the drying box 1. By monitoring the humidity change inside the drying box 1 in real time through the humidity sensor 19, the precise control of the drying process can be realized more scientifically, ensuring that the melon seeds are discharged after being dried to an appropriate degree.

[0024] Working principle: When in use, the melon seeds are put into the drying box 1 from the feed pipe 2. Heat is generated inside the drying box 1 through the operation of the heating wire 5. Part of the generated heat is transferred to the rotating tube 8 through the heat transfer assembly and then released to the middle position of the drying box 1 through the first air outlet holes 10, so that the hot air can also quickly contact the melon seeds in the middle. At the same time, the driving mechanism drives the rotating tube 8 to rotate, and then drives the dispersing rods 9 to rotate. The multiple dispersing rods 9 stir the melon seeds, so that the melon seeds remain in a dispersed state during the drying process, preventing the melon seeds from sticking to each other during the drying process. The hot air can more fully cover the surface of the melon seeds, increasing the contact area between the hot air and the melon seeds, and distributing the hot air more evenly around the melon seeds, thereby realizing the uniform and rapid drying of the melon seeds. The dried melon seeds are discharged from the drying box 1 through the discharge pipe 3.

[0025] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
