Description

Technical Field

[0001] The utility model belongs to the technical field of melon seed processing, in particular to a drying device for melon seed processing. Background Art

[0002] Melon seed processing involves putting freshly picked melon seeds through a series of processes to ensure they meet the standards for consumption or sale. This process covers key steps such as cleaning, drying, shelling, screening, and packaging, aiming to ensure the quality and taste of the melon seeds. First, the freshly picked melon seeds need to be initially cleaned to remove surface dirt and impurities. The seeds are then sent to the drying equipment to reduce the moisture content, prevent mold and extend their shelf life. The use of efficient drying equipment not only improves processing efficiency, but also ensures the integrity of the shelling process, thereby reducing the phenomenon of breakage caused by excessive moisture.

[0003] The existing drying equipment for melon seed processing has shortcomings: the drying equipment currently on the market generally uses drum heat transfer technology to dry melon seeds. However, the movement of melon seeds inside the drum lacks order, which may lead to melon seed accumulation and blockage during the drying process. These conditions cause some melon seeds to stay in the same position for a long time and cannot receive heat evenly, resulting in uneven heating. In addition, the dried melon seeds themselves contain a lot of heat. If they are not cooled immediately, it will have a negative impact on subsequent processing steps. When the melon seeds are transported to the next work area, due to the lack of a cooling mechanism in the current equipment, the high temperature of the melon seeds may cause deformation or deterioration of the packaging material, thereby affecting the packaging quality of the product.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 6 As shown, the utility model provides a drying device for melon seed processing, comprising a drying drum 1, a cooling structure 2 located on the left side and below the drying drum 1, and a drying structure 3 located outside and inside the drying drum 1;

[0023] The cooling structure 2 includes a cooling box 21 connected to one end of the drying drum 1, a cooling fan 22 mounted on the top of the cooling box 21, and a feeding pipe 23 connected to the cooling box 21 and located at the bottom of the cooling box 21. The bottom of the feeding pipe 23 is connected to a transmission pipe 24. The left end of the transmission pipe 24 is fixedly connected to a servo motor 25. The output end of the servo motor 25 is fixedly connected to an auger rod 26.

[0024] The drying structure 3 includes a lifting plate 31 assembled inside the drying drum 1, two transmission gears 32 fixedly connected to the outer wall of the drying drum 1, and a protective cover 33 sleeved on the outside of the transmission gear 32. The outer wall of the transmission gear 32 is meshed with a linkage gear 34, and the outer wall of the protective cover 33 is fixedly connected to a reduction motor 35. The output end of the reduction motor 35 extends to the interior of the protective cover 33 and is fixedly connected to the linkage gear 34.

[0025] The above scheme is adopted: through the cooperation of the cooling structure 2 and the drying structure 3, when the melon seeds are fed into the drying drum 1 for drying, hot air is introduced into the drum through the air inlet pipe 51, and the drying drum 1 rotates accordingly. The melon seeds are carried to the air by the lifting plate 31 and then scattered. In this process, the contact area between the melon seeds and the hot air increases, ensuring that the material is evenly heated. With the action of the hot air, the moisture in the material evaporates to achieve the purpose of drying. At the same time, the generated gas is discharged out of the drum through the exhaust fan 13. During the drying process, the melon seeds will continuously enter the cooling box 21. At this time, the air cooler 22 starts working and delivers cold air into the cooling box 21. The cold air and the melon seeds enter the transmission pipe 24 together. With the help of the transmission of the auger rod 26, the cooled melon seeds are taken out. This not only achieves uniform heating and drying of the melon seeds, but also has the function of efficient cooling.

[0026] like Figures 1 to 6 As shown, it also includes a support base 4 located in the middle of the transmission pipe 24 and the drying drum 1 and a blanking frame 5 connected to the drying drum 1 and located at the left end of the drying drum 1. The outer wall of the blanking frame 5 is provided with an air inlet pipe 51 connected thereto, and the other end of the transmission pipe 24 is plugged with a blocking block 241. The outer wall of the transmission pipe 24 is provided with a fixing plate 242, and the transmission pipe 24 is fixedly connected to the bottom of the support base 4 through the fixing plate 242.

[0027] The above scheme is adopted: During the drying process of melon seeds, the staggered arrangement and different angles of the lifting plates 31 play a vital role. This diversified design provides a solid foundation for the uniform drying of the melon seeds. When the melon seeds enter the drying drum 1, due to the staggered arrangement of the lifting plates 31, the movement trajectory of the melon seeds in the drum becomes more complex and diverse. The lifting plates 31 at different positions scoop up and push the melon seeds at different angles, ensuring that the melon seeds move and tumble in all directions in the drum. At the same time, the air inlet pipe 51 is connected to an external hot air blower. The hot air generated by the hot air blower continuously enters the interior of the drying drum 1, providing a stable and sufficient heat source for drying the melon seeds. The hot air blower can accurately adjust the temperature and flow rate of the hot air to meet actual needs. After entering the drying drum 1, the hot air will first fill the entire drum space, forming a uniform thermal environment. Thanks to the action of the lifting plates 31, the melon seeds can continuously exchange heat with the hot air during the continuous movement and tumbling process. The heat in the hot air is quickly transferred to the melon seeds, causing the moisture in the melon seeds to be efficiently vaporized, thereby achieving the drying effect.

[0028] like Figures 1 to 6As shown, the top of the support base 4 is provided with equidistantly distributed support columns 41, the outer walls of the support columns 41 are in contact with the outer wall of the drying cylinder 1, and a locking ring 11 is fixedly connected to the middle of the outer wall of the drying cylinder 1. A circular opening connected to the drying cylinder 1 is provided on the inner wall of the locking ring 11, and a blocking net 12 is installed on the inner wall of the circular opening, and an exhaust fan 13 is provided above the blocking net 12. The cooling box 21 and the blanking frame 5 are both rotatably connected to the two ends of the drying cylinder 1 through bearings and are fixedly connected to the two left sides of the support base 4.

[0029] The above solution is adopted: by providing the blocking net 12, the melon seeds can be effectively prevented from being thrown out from the circular opening, while allowing the gas generated by the evaporation of water to be discharged through the exhaust fan 13.

[0030] The working principle and use process of this utility model:

[0031] First, the melon seeds to be dried are fed into the drying drum 1, the reduction motor 35 is started, and the transmission gear 32 is driven to rotate through the linkage gear 34, so that the drying drum 1 starts to rotate. At the same time, the external hot air blower delivers hot air to the drying drum 1 through the air inlet pipe 51. The staggered and angled lifting plates 31 in the drying drum 1 continuously scoop up the melon seeds into the air and scatter them during the rotation process, ensuring that the melon seeds are fully in contact with the hot air and increasing the contact area, thereby ensuring that the material is evenly heated. With the action of the hot air, the moisture in the melon seeds is vaporized and dried, and the generated gas is discharged through the exhaust fan 13. During the continuous drying process, the melon seeds will gradually enter the cooling box 21. At this time, the cold air blower 22 is started to deliver cold air into the cooling box 21. The cold air and the melon seeds enter the transmission pipe 24 together, and the servo motor 25 is started to drive the auger rod 26 to rotate. The auger rod 26 pushes the cooled melon seeds to move in the transmission pipe 24. Finally, the cooled melon seeds can be taken out from one end of the transmission pipe 24.
