[0002] In recent years, microbial fermented feed has developed rapidly in livestock breeding feed. Microbial fermented feed ferments a variety of mixed raw materials by adding beneficial bacteria, and utilizes the synergistic effect of different bacteria to degrade large molecular proteins in the raw materials and reduce the content of anti-nutritional factors.

[0033] Embodiment 1:

[0034] Reference Figure 1 An automated fermentation machine shown includes a fixed frame 100 and a first rotating bin 200 rotatably connected to the fixed frame 100, a bearing is provided between the fixed frame 100 and the first rotating bin 200, a rotating motor is provided outside the fixed frame 100 to drive the first rotating bin 200 to rotate, a first feeding device 110 is provided at one end of the first rotating bin 200, and the first feeding device 110 is used to transport the fermentation material into the first rotating bin 200. Specifically, in the present embodiment, the first feeding device 110 is a spiral feeding device, and the first feeding device 110 is dynamically sealed with the first rotating bin 200; both ends of the first rotating bin 200 are rotatably sealed and connected to a discharge bin 130, and the discharge bin 130 is fixed to the ground.

[0035] like Figure 3 As shown, the first rotating bin 200 is a cylinder containing a cavity a210 inside, and the first rotating bin 200 can rotate around the axis of the cylinder and the axis is arranged horizontally; the inner wall of the first rotating bin 200 is provided with a spiral baffle a220, and the spiral baffle a220 is continuously distributed on the inner wall of the first rotating bin 200 along the right spiral line direction. When the first rotating bin 200 rotates, the solid fermentation material in the bin rolls on the inner wall of the first rotating bin 200 according to its own weight. Due to the existence of the spiral baffle a220, some solid fermentation materials move forward along the spiral baffle to one end of the first rotating bin 200. It should be noted that: Figure 6As shown, in this embodiment, the spiral baffle is integrally formed. Of course, under the premise of satisfying the same effect, multiple baffles 221 can be used, such as Figure 7 shown.

[0036] A second rotating bin 300 is disposed in the cavity a210 , and the second rotating bin 300 , the first rotating bin 200 and the first feeding device 110 are coaxially arranged.

[0037] like Figure 4 As shown, the second rotating bin 300 is a cylinder containing a cavity b inside, and the second rotating bin 300 can rotate around the axis of the cylinder and the axis is horizontally arranged; the cavity b passes through the top and bottom surfaces of the second rotating bin 300, and a plurality of through holes a320 passing through the bin wall are arranged on the bin wall of the second rotating bin 300, and the through holes a320 are used to leak out materials, and the inner wall of the second rotating bin 300 is provided with a spiral baffle b310, and the spiral baffle b310 is continuously distributed on the inner wall of the second rotating bin 300 along the left spiral line direction, and the second rotating bin 300 is connected to the first rotating bin 200 by a connecting rod 180. Specifically, in this embodiment, as shown in Figure 8 As shown, the connecting rod 180 is a hollow rod and a small ball 181 is provided inside; the rotation of the first rotating bin 200 drives the second rotating bin 300 to rotate together. On the one hand, the solid fermentation material in the second rotating bin 300 rolls on the inner wall of the second rotating bin 300 according to its own weight. Due to the existence of the spiral baffle b310, some solid fermentation materials move along the spiral baffle to one end of the second rotating bin 300. Since the spiral baffle a220 and the spiral baffle b310 are set in opposite directions, the stacking end of the second rotating bin 300 is opposite to the stacking end of the first rotating bin 200. It should be noted that the spiral baffle b310 can also be integrally formed or composed of multiple baffles 221; on the other hand, the small ball 181 in the connecting rod 180 moves up and down and hits the second and first rotating bins 200 driven by the rotation of the second rotating bin 300 to provide vibration; promotes the solid fermentation to leak out through the through hole a320 in the second rotating bin 300, and reduces the possibility of the fermentation material sticking to the bin wall.

[0038] Reference Figure 1 As shown, the other end of the first rotating bin 200 is provided with a second feeding device 120, and the second feeding device 120 extends into one end of the second rotating bin 300, referring to Figure 1 , as shown in FIG3 , a material baffle a230 is provided in the vertical direction of the second feeding device 120, and the material baffle a230 is fixedly connected to the first rotating bin 200 to block the material inside the first rotating bin 200, change its landing surface, and make the solid fermentation material in the first rotating bin 200 fall from the air; the second feeding device 120 is used to receive the material blocked by the material baffle a230 and transport the material into the second rotating bin 300, refer to FIG3 for details. Figure 5As shown, the second feeding device 120 includes: an arc-shaped material trough 121 and a screw rod 122. The arc-shaped material trough 121 is fixedly connected to the discharge bin 130, and the screw rod 122 is connected to a rotating motor located outside the first rotating bin 200. The screw rod 122 rotates relative to the arc-shaped material trough 121. The arc-shaped material trough 121 is used to receive the solid fermentation material blocked by the material baffle a230. The screw rod 122 is used to send the solid fermentation material in the arc-shaped material trough 121 into the second rotating bin 300 to complete the material exchange from the first rotating bin 200 to the second rotating bin 300. At the same time, the second feeding device 120, the first rotating bin 200 and the second rotating bin 300 should be coaxially arranged to ensure that no excess centrifugal force is generated when the cylindrical first rotating bin 200 rotates. Of course, it should be noted that other second feeding devices 120 can also be used while satisfying the effect of material exchange from the first rotating bin 200 to the second rotating bin 300. Fig.10 The third feeding device 450 shown in the figure can be fixedly connected to the first rotating bin 200, and can also be connected to the motor connected to the rotating rod. It is a horizontally arranged truncated cone containing a cavity c. The cavity c passes through the top and bottom surfaces of the truncated cone. A notch 451 passing through the top and bottom surfaces is provided along the side of the truncated cone. The solid fermentation product blocked by the material baffle a230 is received through the notch 451, and then the solid fermentation product is sent into the second rotating bin 300 by utilizing the height difference.

[0039] The solid fermentation material in the second rotating bin 300 re-enters the first rotating bin 200 due to the left and right movement of the spiral baffle b310 to complete a cycle of stirring. At the same time, a plurality of through holes a320 for material leakage are provided on the inner wall of the second rotating bin 300, thereby ensuring the material exchange rate and uniform stirring efficiency in the two barrels.

[0040] Specifically, in this embodiment, if Figure 1 As shown, the first rotating chamber 200 further includes a humidifying pipe 140 for increasing the humidity of the fermented product, a hot air pipe 150 for increasing the temperature, and an oxygenating pipe 160 for increasing oxygen, as shown in FIG. Figure 2 As shown; in order to dynamically detect the temperature, humidity and oxygen content in the automatic fermentation machine, a temperature sensor 151, a humidity sensor 141 and an oxygen detection device 161 are also provided in the first rotating bin 200, and the three are directly connected to the terminal for inspection personnel to observe.

[0041] Specifically, in this implementation, if Figure 1 As shown, in order to ensure the fermentation temperature, a heat preservation layer 170 is further provided on the inner wall of the first rotary bin 200 .

[0042] Embodiment 2:

[0043] This embodiment is further provided with a third rotating chamber 400 installed in the second rotating chamber 300 on the basis of the first embodiment. Fig. 9 As shown, the third rotating bin 400 is a cylinder containing a cavity d420 inside, and the third rotating bin 400 can rotate around the axis of the cylinder, and the axis is arranged horizontally; the cavity d420 passes through the top and bottom surfaces of the third rotating bin 400, and a plurality of through holes b430 passing through the bin wall are arranged on the bin wall of the third rotating bin 400, and a spiral baffle c410 is arranged on the inner wall of the third rotating bin 400, and the spiral baffle c410 is continuously distributed on the inner wall of the third rotating bin 400 along the right spiral line direction; the third rotating bin 400 is fixedly connected to the second rotating bin 300;

[0044] A third feeding device 450 is provided at the other end of the second rotating bin 300. The third feeding device 450 can be fixedly connected to the second rotating bin 300, and can also be connected to the motor outside the first rotating bin 200. A material baffle b440 is provided in the vertical direction of the third feeding device 450. The material baffle b440 is fixedly connected to the second rotating bin 300 to block the material inside the second rotating bin 300 and change its landing surface; the third feeding device 450 is used to receive the material blocked by the material baffle b440 and transport the material into the third rotating bin 400.

[0045] Specifically, refer to Fig.10 The third feeding device 450 is a horizontally arranged truncated cone containing a cavity c. The cavity c passes through the top and bottom surfaces of the truncated cone. A notch 451 passing through the top and bottom surfaces is provided along the side of the truncated cone. The solid fermentation product blocked by the material baffle b440 is received through the notch 451, and then the solid fermentation product is sent into the third rotating bin 400 by utilizing the height difference.

[0046] It should be noted that the working principle of the third rotating bin 400 is consistent with that of the second rotating bin 300, and the rotation direction of the spiral baffle c410 is opposite to that of the spiral baffle b310, ensuring that when the third rotating bin 400 rotates following the second rotating bin 300, the solid fermentation material moves in the opposite direction.

[0047] By setting up the third rotating bin 400, the efficiency of material exchange and contact in the automatic fermentation machine is increased. It should be noted that, according to this principle, a fourth rotating bin located in the third rotating bin 400 can also be added.
