Description

Technical Field

[0001] This utility model relates to the field of sunflower seed processing technology, and more specifically, it relates to a sunflower seed circulating drying and air separation device. Background Technology

[0002] The seeds of melons, specifically referring to roasted and edible seeds such as pumpkin seeds and watermelon seeds, are also called melon seeds or colloquially, "side fruit." There are many varieties, including sunflower seeds, sea cucumber seeds, hanging melon seeds, watermelon seeds, pumpkin seeds, cucumber seeds, and loofah seeds. Most melon seeds available can be roasted and eaten. To improve the taste, they are often dried and dehydrated before consumption.

[0003] A search revealed that Chinese utility model patent application number CN202221053797.8 discloses a sunflower seed circulating drying and air separation device, including a drying box. A vertically arranged partition is fixedly connected to the inner side of the drying box, and multiple horizontally arranged air spray pipes are fixedly connected to the partition. A feeding box is arranged on the upper outer side of the drying box, and a first connecting pipe is connected to the bottom of the feeding box. A circular adjusting sleeve is connected to the lower end of the first connecting pipe, and a motor is fixedly connected to one side of the adjusting sleeve.

[0004] In use, the motor drives the rotating disc to rotate, which causes the annular rubber ball on the outer surface of the disc to rotate inside the adjusting sleeve. This allows the sunflower seeds between the adjusting sleeve and the annular rubber ball to be fed evenly through the second connecting pipe into the inside of the drying chamber. The sunflower seeds then undergo free fall motion inside the drying chamber, and are dried by hot air sprayed from the air pipe, ensuring that each sunflower seed is dried evenly.

[0005] However, the diameter of the second connecting pipe is fixed, and the sunflower seeds can only fall from inside the second connecting pipe. The range of sunflower seed dispersion is also limited to the size of the inner diameter of the second connecting pipe, which makes the dispersion range of sunflower seeds relatively small and the drying effect of sunflower seeds relatively poor. In addition, the feeding box is located above the drying box. When people add sunflower seeds into the feeding box, they need to climb up to add the sunflower seeds, which increases the labor intensity of people and also poses a certain degree of danger.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a sunflower seed circulating drying and air separation device, which has the following beneficial effects:

[0019] 1. The sunflower seeds at the bottom of the drying chamber fall into the auger through the discharge pipe and the first connecting pipe. The auger then transports the sunflower seeds to the upper part of the drying chamber through the second connecting pipe. The sunflower seeds fall onto the first and second air boxes and slide evenly into the drying chamber, which facilitates the large-area dispersion of the sunflower seeds inside the drying chamber. At the same time, the hot air blown evenly through the multiple air outlets on the first and second air boxes facilitates the circulation and drying of the sunflower seeds, increases the drying area, improves the uniformity of drying, and enhances the drying effect.

[0020] 2. By setting up a feeding box and a third connecting pipe, people only need to add sunflower seeds into the feeding box. The sunflower seeds inside the feeding box fall to the bottom of the auger through the third connecting pipe. The auger then transports the sunflower seeds into the drying box. Since the height of the feeding box is lower than the height of the drying box, the height at which people add sunflower seeds is reduced, avoiding the need for people to climb to add sunflower seeds, thus reducing the workload and danger.

[0021] 3. The rotating shaft facilitates the rotation of the cylinder and the blocking plate, making it easy to adjust the position of the blocking plate. During the circulating drying process of sunflower seeds, the blocking plate is rotated to the position of the discharge pipe to seal the discharge pipe and prevent sunflower seeds from falling into the discharge pipe. When the dried sunflower seeds are discharged through the discharge pipe, the blocking plate is rotated to the position corresponding to the first connecting pipe to seal the first connecting pipe and prevent sunflower seeds from falling into the first connecting pipe.

[0031] Please see Figures 1-5A circulating drying and air-separation device for sunflower seeds includes a drying chamber 1. Two first air boxes 3 are fixedly connected inside the drying chamber 1 via multiple connecting rods 2. The top of each first air box 3 has a conical structure. Two second air boxes 4 are also fixedly connected inside the drying chamber 1. The top of each second air box 4 has a conical groove structure. A material discharge port 5 is located in the middle of each second air box 4. The two first air boxes 3 and two second air boxes 4 are staggered. Multiple air outlets 6 are located at the top of each of the first and second air boxes 3 and 4. Each of the two first air boxes 3 and two second air boxes 4 is connected to a blowing mechanism via ventilation pipes 7. The blowing mechanism includes a blower 13 and a heating box 14 containing heating wires. The blower 13 is mounted on the heating box 14. The air outlet is connected to an air outlet pipe 15, which is connected to multiple ventilation pipes 7. When the blower 13 is working, the air heated inside the heating box 14 is blown into the first air box 3 and the second air box 4 through the air outlet pipe 15 and multiple ventilation pipes 7. The bottom end of the drying box 1 is connected to a discharge pipe 8, which is also equipped with a valve 18. The discharge pipe 8 is connected to an auger 10 through a first connecting pipe 9. The auger 10 is fixedly connected to the drying box 1 through a connecting seat 26 to ensure the stability of the connection between the auger 10 and the drying box 1. The top of the drying box 1 is equipped with a box cover 11, which is connected to an exhaust pipe 25 to facilitate the exhaust of gas inside the drying box 1. The output end of the auger 10 is connected to the feed port on the box cover 11 through a second connecting pipe 12.

[0032] Specifically, the sunflower seeds at the bottom of the drying chamber 1 fall into the auger 10 through the discharge pipe 8 and the first connecting pipe 9. The auger 10 then transports the sunflower seeds to the upper part of the drying chamber 1 through the second connecting pipe 12. The sunflower seeds fall onto the first air box 3 and the second air box 4, and slide evenly from the first air box 3 and the second air box 4 into the drying chamber 1, which facilitates the large-area dispersion of the sunflower seeds inside the drying chamber 1. At the same time, the hot air blown evenly from the multiple air outlets on the first air box 3 and the second air box 4 facilitates the circulation and drying of the sunflower seeds, increases the drying area, improves the uniformity of drying, and enhances the drying effect.

[0033] Please see Figure 1 and Figure 4 A feed box 16 is placed on one side of the auger 10. The height of the feed box 16 is lower than that of the drying box 1. The bottom end of the feed box 16 is connected to the bottom of the auger 10 through a third connecting pipe 17. A valve 18 is installed on the third connecting pipe 17, and the opening and closing of the third connecting pipe 17 is controlled by the valve 18.

[0034] Specifically, by setting up a feeding box 16 and a third connecting pipe 17, people only need to add sunflower seeds into the feeding box 16. The sunflower seeds inside the feeding box 16 fall to the bottom of the auger 10 through the third connecting pipe 17, and the auger 10 transports the sunflower seeds into the drying box 1. Since the height of the feeding box 16 is lower than the height of the drying box 1, the height at which people add sunflower seeds is reduced, avoiding the need for people to climb to add sunflower seeds, thus reducing the workload and danger.

[0035] Please see Figure 1 and Figure 5 The discharge pipe 8 is connected to the discharge pipe 19, which facilitates the discharge of sunflower seeds after drying inside the drying box 1. A sealing plate 20 is installed at the bottom of the discharge pipe 8. A rotating shaft 21 is rotatably connected to the sealing plate 20. A cylinder 22 is fixedly connected to one side of the rotating shaft 21 inside the discharge pipe 8. A blocking plate 23 that matches the inner wall of the discharge pipe 8 is fixedly connected to the top of the cylinder 22. A handle 24 is fixedly connected to the bottom of the rotating shaft 21, which facilitates the rotation of the rotating shaft 21.

[0036] Specifically, rotating the shaft 21 facilitates the rotation of the cylinder 22 and the blocking plate 23, and makes it easy to adjust the position of the blocking plate 23. During the process of circulating and drying the sunflower seeds, the blocking plate 23 is rotated to the position of the discharge pipe 19 to block the discharge pipe 19 and prevent the sunflower seeds from falling into the discharge pipe 19. When the dried sunflower seeds are discharged through the discharge pipe 19, the blocking plate 23 is rotated to the position corresponding to the first connecting pipe 9 to block the first connecting pipe 9 and prevent the sunflower seeds from falling into the first connecting pipe 9.

[0037] In summary, when using the overall equipment:

[0038] Close valve 18 on discharge pipe 8, add the sunflower seeds to be dried into the feed box 16. The sunflower seeds inside the feed box 16 fall through the third connecting pipe 17 to the bottom of the auger 10. The auger 10 then transports the sunflower seeds into the drying chamber 1. After a certain amount of sunflower seeds have been added into the drying chamber 1, close valve 18 on the third connecting pipe 17 and simultaneously open valve 18 on discharge pipe 8. The sunflower seeds at the bottom of the drying chamber 1 fall through discharge pipe 8 and the first connecting pipe 9 into the auger 10. The auger 10 then transports the sunflower seeds through the second connecting pipe 12 to the upper part of the drying chamber 1. The sunflower seeds fall onto the first air box 3 and the second air box 4, and the seeds are evenly distributed from the first air box 3 and the second air box 4. The seeds slide into the drying chamber 1, while the blower 13 operates to blow the heated air inside the heating chamber 14 through the air outlet 15 and multiple ventilation pipes 7 into the first air box 3 and the second air box 4. The hot air is blown out evenly through the air outlets on the first air box 3 and the second air box 4, and the hot air comes into even contact with the scattered sunflower seeds to dry them. After the sunflower seeds are dried, the rotating shaft 21, the cylinder 22 and the blocking plate 23 are rotated to the position corresponding to the first connecting pipe 9, and the first connecting pipe 9 is sealed by the blocking plate 23. At the same time, the auger 10 operates to transport the sunflower seeds inside the first connecting pipe 9 and the auger 10 into the drying chamber 1. The sunflower seeds inside the drying chamber 1 are discharged through the discharge pipe 8 and the discharge pipe 19.
