The outlet 15 is provided with a spiral blade 17 inside the isolation cylinder 14, and the spiral blade 17 is fixedly connected to the outer wall of the rotating shaft 7. The starting motor 8 drives the rotating shaft 7 to rotate, and the raw materials fall into the bottom of the mixing tank 1 and gradually accumulate together. At this time, the multiple stirring rods 13 fixed on the rotating shaft 7 will stir the raw materials to mix them. At the same time, the interior of the mixing tank 1 is separated into two spaces by the isolation cylinder 14. The spiral blade 17 inside the isolation cylinder 14 will drive the raw materials at the bottom to spiral upward to the top, and enter the outside of the isolation cylinder 14 through the outlet 15, thereby improving the mixing effect.

[0034] Combine Figure 4-5 A separation and flow-stopping assembly is provided inside the mixing tank 1. The separation and flow-stopping assembly includes two pipes 6. The two pipes 6 are fixedly connected to the inlet end of the mixing tank 1. The inlet end of the pipe 6 is fixedly connected to an entry bucket 5, and the entry bucket 5 is located at the top of the pipe 6. The bottom of the pipe 6 is fixedly connected to a reinforcing rib 3, and the reinforcing rib 3 is fixedly connected to the outer wall of the mixing tank 1. The raw materials to be puffed are put into the two entry buckets 5, and the raw materials will enter the interior of the mixing tank 1 through the pipe 6.

[0035] Combine Figure 4-5, a feed plate 11 is fixedly connected to the inside of the mixing tank 1, and the feed plate 11 is rotatably connected to the outer wall of the rotating shaft 7. The outer wall of the feed plate 11 is provided with evenly distributed slots 12. The top of the feed plate 11 is slidably connected to a scraper 10. The side of the scraper 10 away from the inner wall of the mixing tank 1 is fixedly connected to a fixed block 9. The fixed block 9 is fixedly connected to the outer wall of the rotating shaft 7. A feed plate 20 is provided at the bottom of the feed plate 11. The feed plate 20 is fixedly connected to the inner wall of the mixing tank 1. The outer wall of the feed plate 20 A uniformly distributed slot 21 is provided, and the slot 21 does not correspond to the slot 12.

The fixed block 2 18 is fixedly connected to the outer wall of the rotating shaft 7. The top of the mixing tank 1 is provided with uniformly distributed heat dissipation holes 4. The bottom of the mixing tank 1 is fixedly connected to uniformly distributed support legs 2. Because the rotating shaft 7 is in a rotating state, the fixed block 9 fixed on the rotating shaft 7 is rotated synchronously, and the corresponding The two scrapers 10 fixed to the fixed block 9 also rotate. Since there are multiple holes 12 for passing through on the outer wall of the feed plate 11, the raw materials will fall to the bottom of the feed plate 11 through the holes 12. Since the scraper 10 is in contact with the holes 12, it can drive the raw materials on the feed plate 11 to move, accelerate the passage of the raw materials, and prevent the raw materials from piling up. The raw materials passing through the holes 12 will fall to the top surface of the feed plate 20. At the same time, the feed plate 20 also has holes 21 for passing through, which can The raw materials can fall to the bottom of the feed plate 20. At the same time, the fixed block 18 fixed on the rotating shaft 7 will also drive the scraper 19 to move on the top surface of the feed plate 20, pushing the raw materials to accelerate through the hole slot 21. Since the feed plate 11 and the feed plate 20 are arranged above the outlet 15, they play a certain role in blocking the ejection, preventing the feed inside the mixing tank 1 from being ejected to the outside during the puffing and stirring. Since the hole slot 21 and the hole slot 12 do not correspond to each other, while having a heat dissipation function, it further prevents the ejection of the feed during the puffing process.

[0036] Working principle: Before use, the user should first check whether the device is damaged. After confirming that the device is not damaged, start the motor 8 to drive the rotating shaft 7 to rotate. At the same time, the raw materials that need to be expanded can be put into the two inlet buckets 5. The raw materials will enter the interior of the mixing tank 1 through the pipe 6 and fall onto the feeding plate 11. Because the rotating shaft 7 is in a rotating state, the fixed block 9 fixed on the rotating shaft 7 is rotated synchronously, and the two scrapers 10 fixed to the fixed block 9 are also rotated accordingly. Because there are multiple hole slots 12 on the outer wall of the feeding plate 11 for passing through, the raw materials will pass through the hole slots 12 and fall to the bottom of the feeding plate 11. Because the scraper 10 contacts the hole slots 12, it can drive the raw materials on the feeding plate 11 to move, accelerate the passage of the raw materials, and prevent the raw materials from piling up. The raw materials passing through the hole slots 12 will fall onto the top surface of the feeding plate 20. At the same time, the feeding plate 20 also has hole slots 2 for passing through. 21, which can make the raw materials fall to the bottom of the feed plate 20. At the same time, the fixed block 21 fixed on the rotating shaft 7 will also drive the scraper 21 to move on the top surface of the feed plate 20, pushing the raw materials to accelerate through the hole groove 21, and then the raw materials fall into the bottom of the mixing tank 1 and gradually accumulate together. At this time, the multiple stirring rods 13 fixed on the rotating shaft 7 will stir the raw materials to mix them. At the same time, the interior of the mixing tank 1 is divided into two spaces by the isolation cylinder 14. The spiral blades 17 inside the isolation cylinder 14 will drive the raw materials at the bottom to spiral upward to the top and enter the outside of the isolation cylinder 14 through the outlet 15, thereby improving the mixing effect. Because the feed plate 11 and the feed plate 20 are arranged above the outlet 15, they play a certain role in blocking the ejection, preventing the feed inside the mixing tank 1 from ejecting to the outside during puffing and stirring. Because the hole groove 21 and the hole groove 12 do not correspond, while having a heat dissipation function, it further prevents the ejection of the feed during puffing.
