[0025] 2. By installing the main air outlet pipe and the air outlet branch pipe, the air outlet branch pipe is equipped with an opening and closing mechanism. When the maturation tank is transferred to the maturation and sterilization section, the opening and closing mechanism opens, and the steam pipe supplies air to the corresponding air outlet branch pipe, and then the air evenly enters the maturation tank through multiple air outlet holes, which can evenly and quickly mature and sterilize the feed.

[0026] 3. By installing the main air blowing pipe, air blowing branch pipe and air blowing branch pipe, when the maturation tank is transferred to the cooling section, the opening and closing mechanism on the air blowing branch pipe is opened, and the air blowing pipe is connected to the blower to blow air to the corresponding air blowing branch pipe, and then blow air into the maturation tank through multiple air blowing holes, which can cool the feed and pass impurities through the gaps between the feeds, and then pass through the annular filter to achieve the filtering process.

[0039] A mounting port 30 is provided in the middle of the turntable 8, and an air intake main pipe 14 extending into the mounting port 30 is installed on the rear side plate 1. The rear end of the air intake main pipe 14 is connected to the steam pipe through a rotary joint, and the front end of the blowing main pipe 25 is connected to the blast pipe through a rotary joint. The extended end of the air intake main pipe 14 is fixedly connected to a plurality of air outlet branch pipes 15, and the plurality of air outlet branch pipes 15 extend into the corresponding maturation tank 7 respectively. A plurality of air outlet holes 17 are evenly distributed on the side wall of a section of the air outlet branch pipe 15 located in the maturation tank 7. The steam in the steam pipe enters the connected air outlet branch pipe 15 through the air outlet main pipe 14, and is finally evenly blown into the maturation tank 7 through the plurality of air outlet holes 17, so as to quickly and evenly mature and sterilize the feed.

[0040] The front side plate 31 is provided with a main air blowing pipe 25 extending into the installation opening 30. The extended end of the main air blowing pipe 25 is connected to the annular pipe 24 via a connecting pipe. The side wall of the annular pipe 24 is circumferentially connected with a plurality of air blowing branches 23 that can extend into the corresponding maturation tanks 7. Both ends of the air blowing branches 23 are connected to the air blowing branch pipes 16. The side wall of the air blowing branch pipes 16 is provided with a plurality of air blowing holes that extend into the maturation tanks 7.

[0041] The blowing branch pipe 23 and the air outlet branch pipe 15 are both equipped with an opening and closing mechanism, which includes a partition box 13 installed on the blowing branch pipe 23 and the air outlet branch pipe 15, and a partition plate 27 is elastically installed in the partition box 13 by a spring 26. The bottom of the partition plate 27 is fixedly connected to a push rod 28 extending from the partition box 13, and a magnetic block 29 is installed at the lower end of the push rod 28. The front side of the rear side plate 1 is fixedly installed with a first arc-shaped magnetic plate 18 that cooperates with the magnetic block 29, and the rear side of the front side plate 31 is fixedly installed with two second arc-shaped magnetic plates 32 that cooperate with the magnetic block 29. The wind generated by the blower enters the blowing branch pipe 23 through the blowing main pipe 25, the connecting pipe and the annular pipe 24, and then enters the corresponding blowing branch pipe 16, and finally is blown into the maturation tank 7 through multiple blowing holes. On the one hand, the feed can be cooled, and on the other hand, impurities in the feed can be filtered through the gaps between the feeds and then filtered through the annular filter 4.

[0042] A stirring mechanism is installed in the maturation tank 7, which includes two stirring components and a transmission component. The two stirring components include stirring plates 9 that are rotatably connected to the opposite inner walls of the maturation tank 7 through a rotating shaft. A circular cavity 10 is provided on both sides of the maturation tank 7. The end of the rotating shaft extends into the circular cavity 10. The rear inner wall of the circular cavity 10 is rotatably connected to a rotating rod 12 extending out of the circular cavity 10. The rotating rod 12 is connected to the rotating shaft through a bevel gear pair 11. The transmission component includes a transmission gear 21 fixedly connected to the extended end of the rotating rod 12. An arc-shaped rack 22 that cooperates with the transmission gear 21 is fixedly installed on the front side of the rear side plate 1. When the maturation tank 7 rotates to the maturation and sterilization section, the cooling and screening section, the discharging section and the cleaning section, the transmission gear 21 engages with the arc-shaped rack 22, and drives the stirring plate 9 to rotate through the bevel gear pair 11 to stir the internal feed, thereby improving the maturation and sterilization and cooling and screening effects.

[0043] The feed is loaded into the upper hopper 5, the steam pipe is externally connected to the steam generator, the blast pipe is externally connected to the blower, the starting motor drives the driving gear 20 to rotate, and the turntable 8 is driven to rotate through the gear ring 19. When the maturation tank 7 rotates to the discharge port of the upper hopper 5, the feed automatically falls into the maturation tank 7. When the maturation tank 7 rotates to the maturation and sterilization section, the outlet branch pipe 15 rotates to the first arc-shaped magnetic plate 18. Since the first arc-shaped magnetic plate 18 and the magnetic block 29 repel each other with the same poles, the partition plate 27 is driven upward by the push rod 28, so that the outlet branch pipe 15 is in a conductive state. The steam in the steam pipe enters the conductive outlet branch pipe 15 through the outlet main pipe 14, and is finally blown evenly into the maturation tank 7 through multiple outlet holes 17, which is beneficial to the feed. The feed is quickly and evenly matured and sterilized, and the maturation tank 7 turns away from the maturation and sterilization section and enters the cooling and screening section. At this time, the magnetic block 29 breaks away from the first arc-shaped magnetic plate 18, and the partition plate 27 is reset under the action of the spring 26, closing the air outlet branch 15. At the same time, the opening and closing mechanism on the blowing branch 23 turns to the second arc-shaped magnetic plate 32, and the blowing branch 23 is turned on. The air generated by the blower enters the blowing branch 23 through the blowing main pipe 25, the connecting pipe and the annular pipe 24, and then enters the corresponding blowing branch pipe 16, and finally blows into the maturation tank 7 through multiple blowing holes. On the one hand, it can cool the feed, and on the other hand, it can pass the impurities in the feed through the gaps between the feeds and then pass through the annular filter 4 to realize the filtering process.

[0044] After cooling, the maturation tank 7 moves to the discharge channel 2 position to realize the automatic discharge process. When it continues to move to the cleaning section, the blowing branch pipe 23 passes through another second arc-shaped magnetic plate 32, and then the opening and closing mechanism opens, which can blow the feed remaining in the maturation tank 7 to the collection cover 3 to prevent the feed residue from going through the maturation process again and being over-matured.

[0045] When the maturation tank 7 rotates to the maturation and sterilization section, cooling and screening section, discharging section and cleaning section, the transmission gear 21 engages with the arc rack 22, and drives the stirring plate 9 to rotate through the bevel gear pair 11 to stir the feed inside, thereby improving the maturation and sterilization and cooling and screening effects.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
