When the lifting ring sleeve 501 goes up, the length between the first turning plate 504 and the second turning plate 505 will become shorter, and drive the grain to move upward, so that the grain is turned out to the periphery. When the lifting ring sleeve 501 goes down, the length between the first turning plate 504 and the second turning plate 505 will gradually become longer, and enter the grain, and continue to turn the internal grain out to the periphery, so that the grain can be effectively cooled down, and the stability of the enzyme in low temperature can be better maintained.

Through the elastic force of the reset spring 306, the sliding wheel 302 can be lowered and prevented from detaching from the starting block 301, so that the material turning component 5 can achieve the effect of reciprocating motion.
[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The top of the adapter ring 304 is symmetrically fixed with a guide slide rod 305, which passes through and is slidably arranged on the bottom end of the motor carrier 307, the top of the fixing block 301 is symmetrically provided with a concave portion 3011 and a convex portion 3012, the outer side of the fixing block 301 is symmetrically fixed with a side bracket 3013, the outer side of the motor carrier 307 is symmetrically fixed with a fixed stand 402, the bottom ends of the side bracket 3013 and the fixed stand 402 are fixedly provided with a top end cover 101, and the top end cover 101 is fixedly provided on the top of the low-temperature fermentation cylinder 1.
[0033] When the adapter ring 304 moves up and down, the guide slide rod 305 will move up and down to stabilize the movement of the adapter ring 304, and when the sliding wheel 302 reaches the concave part 3011, the reciprocating carrier plate 303 and the material turning assembly 5 are in a descending state, and when the sliding wheel 302 reaches the convex part 3012, the reciprocating carrier plate 303 and the material turning assembly 5 are in an ascending state, so that the material turning assembly 5 can move up and down to perform the material turning work.

The setting of the slide groove 4011 facilitates the lifting ring sleeve 501 to slide up and down along its trajectory.
[0036] Example 2: Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 , and also includes a scraper structure 6, which is provided with two groups. The scraper structure 6 is symmetrically arranged on the outside of the lifting ring sleeve 501, and the scraper structure 6 includes a fixed sleeve 601, and a return spring 602 is fixedly arranged at one end of the fixed sleeve 601, and an extension rod 603 is fixedly arranged at the other end of the return spring 602, and a resistance reducing inclined surface 607 is fixedly arranged at the other end of the extension rod 603. The fixed sleeve 601 is fixedly arranged on the outside of the lifting ring sleeve 501, and a material passing groove 605 is penetrated on one side of the scraper plate 604, and a notch 606 is arranged on the side of the scraper plates 604 away from each other, and a resistance reducing inclined surface 607 is arranged on the side of the scraper plates 604 away from each other.
[0037] After two cycles of turning the material, the rotation speed of the middle bearing shaft 401 can be increased in the third cycle, so that the scraper plates 604 in the scraper structure 6 move away from each other under the action of centrifugal force, and the scraper plates 604 can fit the inner wall of the low-temperature fermentation cylinder 1. At this time, the pull-back spring 602 will be in an extended state. With the rotation of the middle bearing shaft 401, the scraper plates 604 will fit the inner wall of the low-temperature fermentation cylinder 1 and move, thereby scraping off the grain attached to the inner wall of the low-temperature fermentation cylinder 1, so that the grain can continue to ferment, thereby improving the material utilization rate. Among them, the setting of the material chute 605 is convenient for the material to pass through, and the setting of the resistance reducing slope 607 is convenient for the scraper plates 604 to pass through the material, thereby reducing the resistance of the scraper plates 604 during movement.
[0038] Example 3: Reference Figure 1 , Figure 2 and Figure 8 , also includes an oxygen intake structure 7, the oxygen intake structure 7 includes an external sleeve 701 and an oxygen intake pipe 707, the external sleeve 701, the external sleeve 701 is fixedly arranged on the outer side of the middle bearing shaft 401, the other end of the external sleeve 701 is fixedly arranged with a first magnet 702, a second magnet 703 and a blocking piston 704 are slidably arranged on the inner side of one end of the oxygen intake pipe 707, the second magnet 703 is fixedly arranged on one end of the blocking piston 704, the other end of the blocking piston 704 is fixedly arranged with a return spring 705, the other end of the return spring 705 is fixedly arranged with a fixing ring 706, the fixing ring 706 is fixedly arranged on the inner side of the oxygen intake pipe 707, the oxygen intake pipe 707 passes through the low-temperature fermentation cylinder 1, the other end of the oxygen intake pipe 707 is located on the outer side of the low-temperature fermentation cylinder 1, an air outlet pipe port 708 is arranged on the outer side of one end of the oxygen intake pipe 707, the air outlet pipe port 708 is located on the inner side of the low-temperature fermentation cylinder 1, and the first magnet 702 is a magnet of different polarity.
[0039] Every time the middle bearing shaft 401 rotates one circle, the first magnet 702 in the oxygen inlet structure 7 will approach the second magnet 703 once, and the second magnet 703 will be attracted by the magnetic force of the first magnet 702. The movement of the second magnet 703 drives the blocking piston 704 to move, and the return spring 705 will be stretched. The movement of the blocking piston 704 makes the air outlet pipe 708 and the oxygen inlet pipe 707 connected, so that external oxygen can enter the low-temperature fermentation cylinder 1, increase the oxygen content inside the low-temperature fermentation cylinder 1, maintain the activity of the enzyme, and improve the fermentation quality of the grain.
[0040] Furthermore, when the first magnet 702 leaves the magnetic range of the second magnet 703, the second magnet 703 and the sealing piston 704 will return to their original positions through the elastic force of the return spring 705, preventing excessive oxygen from entering, and the excess gas produced by grain fermentation can be discharged to the outside through the outlet valve 104.
[0041] It should be noted that the stacking height of the grain does not exceed the scraping wall structure 6, which is convenient for air intake and grain fermentation.
[0042] Reference Figure 1 , Figure 2 and Figure 3 A material discharge channel 102 is arranged on the outer side of the top end of the low-temperature fermentation cylinder 1, a material discharge valve 103 is arranged on the bottom end of the low-temperature fermentation cylinder 1, a mechanism protection shell 2 and an air outlet valve 104 are fixedly arranged on the top end cover 101, and the mechanism protection shell 2 is arranged on the outer side of the vertical lifting module 3 and the servo motor 4.
[0043] Excess gas generated by grain fermentation can be discharged to the outside through the gas outlet valve 104, and the fermented grain can be discharged from the discharge valve 103. The mechanism protection shell 2 is used to protect the vertical lifting module 3 and the servo motor 4.
[0044] Working principle: After the grain inside the low-temperature fermentation cylinder 1 has been fermented at low temperature for a period of time, the servo motor 4 is started, and the servo motor 4 drives the middle bearing shaft 401 to rotate. The rotation of the middle bearing shaft 401 is suitable for driving the turning component 5 to move through the vertical lifting module 3. The turning component 5 can drive the grain in the middle to surge outward, thereby reducing the internal heat of the grain; Among them, the vertical lifting module 3 can drive the lifting ring 501 in the material turning component 5 to slide up and down on the outside of the middle bearing shaft 401. When the lifting ring 501 moves up and down, it will drive the first turning plate 504 and the second turning plate 505 to rise and fall through the lifting guide plate 503. When the lifting ring 501 goes up, the length between the first turning plate 504 and the second turning plate 505 will become shorter, and drive the grain to move upward, so that the grain is turned out to the periphery. When the lifting ring 501 goes down, the length between the first turning plate 504 and the second turning plate 505 will gradually become longer, and enter the grain, and continue to turn the internal grain out to the periphery, so that the grain can be effectively cooled, and the stability of the enzyme in low temperature can be better maintained; It should be noted that the rotation of the middle bearing shaft 401 can drive the lifting ring 501, the first turning plate 504 and the second turning plate 505 to rotate together, thereby stirring the grain inside the low-temperature fermentation cylinder 1, thereby helping to distribute oxygen and nutrients more evenly in the grain in the low-temperature fermentation cylinder 1, which helps the microorganisms to better perform respiration and metabolic activities, thereby improving the fermentation efficiency; When the middle bearing shaft 401 rotates, it will drive the sliding wheel 302 in the vertical lifting module 3 to roll on the top of the starting block 301. When the sliding wheel 302 is at the concave part 3011, the material turning component 5 will move downward. When the sliding wheel 302 reaches the convex part 3012, the material turning component 5 will move upward, and the reciprocating carrier plate 303 will change with the height change of the sliding wheel 302. When the reciprocating carrier plate 303 rises, it will lift the transfer ring 304, and the reset spring 306 will be compressed. Through the elastic force of the reset spring 306, the sliding wheel 302 can be lowered and prevented from being separated from the starting block 301, so that the material turning component 5 can achieve the effect of reciprocating motion. The above-mentioned turning process is all carried out at a low speed, and each turning process is one cycle. After two cycles, the third cycle can increase the rotation speed of the middle bearing shaft 401, so that the scraping plates 604 in the scraping structure 6 move away from each other under the action of centrifugal force, and the scraping plates 604 can fit the inner wall of the low-temperature fermentation cylinder 1. At this time, the pull-back spring 602 will be in an extended state. With the rotation of the middle bearing shaft 401, the scraping plates 604 will fit the inner wall of the low-temperature fermentation cylinder 1, and move, thereby scraping off the grain attached to the inner wall of the low-temperature fermentation cylinder 1, so that the grain can continue to ferment, thereby improving the material utilization rate. Among them, the setting of the material chute 605 is convenient for the material to pass through, and the setting of the resistance reducing slope 607 is convenient for the scraping plates 604 to pass through the material, thereby reducing the resistance of the scraping plates 604 during movement; When the middle bearing shaft 401 rotates one circle, the first magnet 702 in the oxygen inlet structure 7 will approach the second magnet 703 once, and the second magnet 703 will be attracted by the magnetic force of the first magnet 702. The movement of the second magnet 703 drives the blocking piston 704 to move, and the return spring 705 will be stretched. The movement of the blocking piston 704 makes the air outlet pipe 708 and the oxygen inlet pipe 707 connected, so that external oxygen can enter the low-temperature fermentation cylinder 1, increase the oxygen content inside the low-temperature fermentation cylinder 1, maintain the activity of the enzyme, and improve the fermentation quality of the grain. When the first magnet 702 leaves the magnetic range of the second magnet 703, the second magnet 703 and the blocking piston 704 will return to their original positions through the elastic force of the return spring 705, preventing excessive oxygen from entering, and the excess gas produced by the fermentation of the grain can be discharged to the outside from the air outlet valve 104.
