[0038] The first aspect of the utility model provides a spiral ribbon jet type bio-enzymatic hydrolysis tank, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, including:

[0039] A tank body 1 having a feed inlet 2 at the top;

[0040] A discharge pipe 3 is provided at the bottom of the tank body 1, and the discharge pipe 3 is communicated with the interior of the tank body 1;

[0041] A first switch valve 5 provided on the discharge pipe 3;

[0042] The ribbon jet bio-enzymatic hydrolysis tank also includes:

[0043] A rotating shaft 9 having one end rotatably connected to the top of the tank body 1, wherein a first passage 17 is provided inside the rotating shaft 9;

[0044] A driving member for driving the rotating shaft 9 to rotate;

[0045] A connecting plate 11 and at least one screw belt 12 arranged in the tank body 1, one end of the connecting plate 11 is fixed to the side surface of the rotating shaft 9, and the interior of the connecting plate 11 is provided with a second channel 15 communicating with the first channel 17; the side of the screw belt 12 is fixed to the other end of the connecting plate 11, and the interior of the screw belt 12 is provided with a third channel 16 communicating with the second channel 15; the side of the screw belt 12 is also provided with a first air hole 13 communicating with the third channel 16;

[0046] An air compression pump is used to introduce air outside the tank body 1 into the first passage 17 .

[0047] In this embodiment, after the rice is placed in the tank body 1 through the feed port 2, a sufficient amount of water is added, and the driving member drives the rotating shaft 9 to rotate. The stirring by the spiral belt 12 is continuous, and the rice in the tank body 1 moves upward along the inclined surface of the spiral belt 12, and quickly forms a circulation inside, and the stirring uniformity is better. At the same time, the continuity encounters less resistance, and the damage to the material is very small. At the same time, the air compression pump is started. During stirring, as the spiral belt 12 rotates, air is continuously ejected from the first air hole 13, and contacts with water and rice over a large area, so that the air can be evenly distributed in the tank body 1, thereby enhancing the respiration of the rice and providing sufficient oxygen. The air dissolves in the water. Therefore, the utility model can greatly reduce the resistance during stirring. At the same time, the air can be evenly distributed in the tank body 1. Here, a method of connecting an air compression pump to the rotating shaft 9 is introduced. Generally, the air outlet of the air compression pump is connected with a conduit. One end of the conduit is connected with a guide block through a flange. The guide block is provided with an air guide hole. The air guide hole is connected with the conduit. A rotating ring is provided on the inner wall of the air guide hole. The rotating ring is rotatably connected with the annular groove provided on the top side of the rotating shaft 9, and the two are sealed by a sealing ring. In this way, when the rotating shaft 9 rotates, the air compression pump can also continuously supply air to the first channel 17.

[0048] Here, if Figure 1 , Figure 2 As shown, the driving member is a reduction motor 8, which is arranged on the top of the tank body 1, and the output shaft of the reduction motor 8 is connected to the rotating shaft 9 for driving the rotating shaft 9 to rotate.

[0049] In addition, since the length of the rotating shaft 9 is relatively long, it may be unstable during long-term rotation. Figure 5 As shown, the spiral ribbon jet bio-enzymatic hydrolysis tank also includes a stabilizing plate 21 fixed to the inner wall of the tank body 1 , the stabilizing plate 21 is provided with a rotating hole, the rotating shaft 9 is rotatably connected to the rotating hole, and the stabilizing plate 21 makes the rotating shaft 9 more stable.

[0050] In order to improve the stirring effect, Figure 2 , Figure 5 As shown, two spiral belts 12 are provided, and the two spiral belts 12 have the same shape.

[0051] In order to make the air ejected from the first air hole 13 more uniform and prevent the first air hole 13 from being blocked by impurities, the first air hole 13 is protected, such as Figure 8 , Fig. 9 As shown, the central axis of the first air hole 13 is inclined in the normal direction of the curved surface of the spiral ribbon 12 where it is located, and the inclination angle is between 30 and 60 degrees. In the actual fermentation process, the closer the tank body 1 is to the bottom, the greater the pressure. Therefore, in order to make the air more uniform in the tank body 1, the distribution density of the first air hole 13 on the spiral ribbon 12 gradually increases from top to bottom.

[0052] Here, if Figure 8 As shown, the spiral belt 12 is a waist-shaped flat tube, or as shown in Fig. 9 As shown, the spiral belt 12 is a semicircular tube.

[0053] As an implementation method, Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the spiral ribbon jet bio-enzymolysis tank also includes a stirring plate 10 located on the spiral ribbon 12, and the stirring plate 10 is arranged on the side surface of the rotating shaft 9. The interior of the stirring plate 10 is provided with a fourth channel 18 connected to the first channel 17, and the outer side surface of the stirring plate 10 is provided with a second air hole 14 connected to the fourth channel 18. This stirring plate 10 plays a role in auxiliary stirring. The width of the stirring plate 10 is very small, so that the resistance will not be too large.

[0054] As an implementation method, Figure 1 , Figure 2 , Figure 5 , Figure 7 As shown, the spiral ribbon jet bio-enzymolysis tank also includes a through pipe 4 and a second switch valve 6 arranged on the through pipe 4. An interlayer 19 is provided near the bottom of the tank body 1. The through pipe 4 is connected to the interlayer 19. The inner wall of the tank body 1 is provided with a plurality of through holes 20, which are connected to the interlayer 19. Here, when water needs to be added, the second switch valve 6 is opened, and water is passed into the through pipe 4 so that the water enters the tank body 1 through the through holes 20. When draining, the second switch valve 6 can be opened. When carbon dioxide needs to be discharged, air can be pumped through the through pipe 4. The provision of the interlayer 19 can prevent rice from being discharged from the through pipe 4 when draining or exhausting.

[0055] In addition, if Figure 1 As shown, a manhole 7 is also provided on the top of the tank body 1 to facilitate subsequent maintenance or inspection.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
