Technical Field

[0001] This invention relates to the field of fermentation technology, and more specifically to a grain fermentation device and method based on probiotics. Background Technology

[0002] Grain microbial fermentation is widely used in the food industry. Foods prepared through grain fermentation are rich in amino acids and can change the taste of food, enhancing its richness.

[0003] Existing fermentation equipment has difficulty cleaning up floating impurities formed during the initial stirring of grains during fermentation. If the floating matter is mold spores or bacterial clumps, it will contaminate the raw materials and affect the fermentation quality. Summary of the Invention

If the floating matter is mold spores or bacterial clumps, it will cause contamination of the raw materials and affect the fermentation quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a probiotic-based grain fermentation device, comprising a fermentation tank, and further comprising:

[0006] The impurity removal mechanism includes a first drive shaft rotatably connected inside the fermenter, a sliding sleeve installed outside the first drive shaft, and multiple filter components installed outside the sliding sleeve. A key pin is fixedly connected to the outer wall of the first drive shaft along its length direction, and a keyway is opened inside the sliding sleeve along its length direction. The key pin is slidably connected inside the keyway. The filter components include a filter frame fixedly connected to the outer wall of the sliding sleeve and a filter screen installed on one side of the outer wall of the filter frame.

[0007] The linkage plate is rotatably connected to the inside of the fermentation tank. The interior of the linkage plate has multiple through-holes, and the filter frame is adapted to the through-holes.

[0008] The extension mechanism includes a guide plate mounted at the bottom of the filter frame and an adjustment assembly for driving the guide plate to rotate.

[0009] Furthermore, a feeding cylinder is installed on the outer wall of one side of the fermentation tank, a discharge pipe is installed at the bottom of the fermentation tank, and a solenoid valve is installed on the discharge pipe.

[0010] Furthermore, the fermenter is also equipped with a stirring mechanism, which includes a linkage shaft rotatably connected inside the first drive shaft, a second drive shaft fixed to the bottom end of the linkage shaft, and a plurality of stirring blades fixedly sleeved outside the second drive shaft. The top end of the second drive shaft abuts against the bottom end of the first drive shaft.

[0011] Furthermore, a bracket is installed on the top of the fermentation tank, and a first motor is installed on the top of the bracket. The output end of the first motor is fixedly connected to the top of the linkage shaft.

[0012] Furthermore, the bracket is also equipped with a drive assembly for driving the first drive shaft to rotate. The drive assembly includes a second motor mounted on the top of the bracket and a first one-way gear mounted outside the first drive shaft.

[0013] The output end of the second motor is fixedly connected to a drive gear, which meshes with the first one-way gear.

[0014] Furthermore, the impurity removal mechanism also includes a lifting assembly installed inside the fermenter. The lifting assembly includes a driven shaft rotatably connected to the inner wall of the top of the fermenter, a reciprocating screw fixedly sleeved outside the driven shaft, and a lifting block threadedly connected to the outside of the reciprocating screw.

[0015] The driven shaft extends to the inner side of the bracket and is rotatably connected to the inner wall of the top of the bracket. A second one-way gear is installed on the outside of the driven shaft, and the second one-way gear meshes with the driving gear.

[0016] The lifting block is also rotatably sleeved on the outside of the sliding sleeve.

[0017] Furthermore, a scavenging pipe is installed on the outer wall of the other side of the fermentation tank, and the scavenging pipe is located at the top of the linkage plate.

[0018] Furthermore, the adjustment assembly includes multiple fixed cylinders hinged to the bottom of one side of the filter frame and a slide rod slidably connected inside the fixed cylinders;

[0019] The top of the guide plate is hinged to the bottom of the other side of the filter frame;

[0020] The bottom end of the slide bar is hinged to the bottom of the guide plate;

[0021] A spring is fixedly connected to the inner wall of the top of the fixed cylinder, and the bottom end of the spring is fixedly connected to the top end of the slide rod.

[0022] A probiotic-based grain fermentation method, employing the aforementioned probiotic-based grain fermentation apparatus, includes the following steps:

[0023] S1. Add the raw materials required for fermentation into the fermentation tank through the feeding cylinder;

[0024] S2. The raw materials inside the fermentation tank are driven to rotate counterclockwise by the stirring mechanism to stir the raw materials and make the impurities float to the surface.

[0025] S3. By driving the filter frame and guide plate to move down, the upper edge of the filter frame is above the liquid level. After the guide plate moves out of the inlet, it is in an inclined state. When the stirring mechanism drives the raw material to rotate counterclockwise, the raw material in the top area will enter the filter frame along the guide plate and filter the impurities in the filter frame through the filter screen.

[0026] S4. By driving the filter frame to move upward and reset, and then driving the filter frame to rotate counterclockwise synchronously, the impurities filtered inside the filter frame are discharged in the opposite direction to the top of the linkage plate through reverse centrifugal force, and the linkage plate then throws the impurities to its edge.

[0027] S5. Remove impurities from the edge of the linkage disk through the impurity extraction tube;

[0028] S6. Repeat steps S3-S4 to process the floating impurities multiple times. After fermentation is complete, open the solenoid valve to discharge the material inside the fermentation tank through the discharge pipe.

[0029] Compared with the prior art, the grain fermentation device and method based on probiotics provided by the present invention have the following beneficial effects:

[0030] 1. By repeatedly cleaning the impurities floating in the raw materials through the impurity removal mechanism, the interference of impurities on the fermentation process is reduced, and the problem of contamination caused by impurities such as mold spores and bacterial clumps is avoided, thereby improving the fermentation quality;

[0031] 2. By reverse-discharging the impurities filtered inside the filter frame to the top of the linkage plate, the impurities on the top of the linkage plate are thrown to its edge during the rotation of the linkage plate. Combined with the impurity removal pipe, the problem of the difficulty in further removing impurities after the raw materials are put into the fermentation tank is solved.

[0032] 3. When the guide plate moves out of the inlet, the spring's rebound force drives the slide rod to move out of the fixed cylinder, thereby driving the guide plate to rotate around its top, making the guide plate tilted. When the stirring mechanism drives the raw material to rotate counterclockwise, the raw material in the top area will enter the filter frame along the guide plate, increasing the range of raw material filtration and impurity removal, and improving the thoroughness of impurity removal.

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] Example: Please refer to Figures 1-6 A probiotic-based grain fermentation device includes a fermentation tank 1, a feeding cylinder 9 installed on the outer wall of one side of the fermentation tank 1, a control valve installed on the feeding cylinder 9, a discharge pipe 10 installed at the bottom of the fermentation tank 1, and a solenoid valve 11 installed on the discharge pipe 10.

[0044] The raw materials required for fermentation are added into the fermentation tank 1 through the feeding cylinder 9. After fermentation is completed, the control solenoid valve 11 is opened to discharge the material inside the fermentation tank 1 through the discharge pipe 10.

[0045] The fermentation tank 1 is also equipped with a stirring mechanism. The stirring mechanism includes a linkage shaft 12 rotatably connected inside the first transmission shaft 2, a second transmission shaft 13 fixedly connected to the bottom end of the linkage shaft 12, and multiple stirring blades 14 fixedly sleeved outside the second transmission shaft 13. The top end of the second transmission shaft 13 abuts against the bottom end of the first transmission shaft 2. A bracket 15 is installed on the top of the fermentation tank 1, and a first motor 16 is installed on the top of the bracket 15. The output end of the first motor 16 is fixedly connected to the top end of the linkage shaft 12.

[0046] By controlling the first motor 16 to drive the linkage shaft 12 to rotate counterclockwise, the second transmission shaft 13 rotates synchronously, thereby driving each stirring blade 14 to stir the raw materials inside the fermentation tank 1.

[0047] Also includes:

[0048] The impurity removal mechanism includes a first drive shaft 2 rotatably connected inside the fermenter 1, a sliding sleeve 3 mounted outside the first drive shaft 2, and multiple filter assemblies mounted outside the sliding sleeve 3. A key pin is fixed to the outer wall of the first drive shaft 2 along its length. A keyway is formed inside the sliding sleeve 3 along its length, and the key pin is slidably connected inside the keyway. Therefore, when the first drive shaft 2 rotates, it drives the sliding sleeve 3 to rotate synchronously. The filter assembly includes a filter frame 6 fixed to the outer wall of the sliding sleeve 3 and a filter screen 7 mounted on one side of the outer wall of the filter frame 6. A drive assembly for driving the first drive shaft 2 is also mounted on the support 15. The drive assembly includes a second motor 17 mounted on the top of the support 15 and a first one-way gear 18 mounted outside the first drive shaft 2. A drive gear 19 is fixed to the output end of the second motor 17. Engaging with the first one-way gear 18, the impurity removal mechanism also includes a lifting assembly installed inside the fermentation tank 1. The lifting assembly includes a driven shaft 20 rotatably connected to the inner wall of the top of the fermentation tank 1, a reciprocating screw 21 fixedly sleeved outside the driven shaft 20, and a lifting block 22 threadedly connected to the outside of the reciprocating screw 21. The top end of the driven shaft 20 extends to the inner side of the support 15 and is rotatably connected to the inner wall of the top of the support 15. A second one-way gear 23 is installed outside the driven shaft 20, and the second one-way gear 23 meshes with the driving gear 19. The lifting block 22 is also rotatably sleeved outside the sliding sleeve 3. The linkage disk 4 is rotatably connected inside the fermentation tank 1. Multiple through-holes 5 are opened inside the linkage disk 4. The filter frame 6 is adapted to the through-holes 5. Therefore, after the filter frame 6 and the filter screen 7 move upward, the raw materials remaining on their outer walls can be scraped off.

[0049] In the initial stage of fermentation, during the counterclockwise stirring of the raw materials, the stirring mechanism controls the second motor 17 to drive the drive gear 19 to rotate counterclockwise. Through the meshing action between the drive gear 19 and the second one-way gear 23, the driven shaft 20 rotates. At this time, the first one-way gear 18 also rotates, but the first transmission shaft 2 does not rotate. When the driven shaft 20 rotates, it drives the reciprocating screw 21 to rotate synchronously, causing the lifting block 22 to move from the top to the bottom of the reciprocating screw 21. This causes the sliding sleeve 3 to move synchronously downwards along the outer wall of the first transmission shaft 2. The filter frames 6 then move downwards along the inner wall of the opening 5, causing the lower edge of the filter frames 6 to fall below the liquid level, while the upper edge remains above the liquid level. Thus, when the stirring mechanism drives the raw materials to rotate counterclockwise, impurities rise to the top of the liquid level during the stirring process. When these impurities pass through the filter frames 6, they are filtered by the filter screen 7. The filter is inside the filter frame 6. By controlling the second motor 17 to drive the reciprocating screw 21 to continue rotating, the lifting block 22 moves from the bottom end of the reciprocating screw 21 to its top end. This causes the filter frame 6 to move upward and reset through the sliding sleeve 3, so that the inner wall of the bottom of the filter frame 6 is at the same level as the top of the linkage disk 4. Then, the second motor 17 drives the drive gear 19 to rotate clockwise. Through the meshing action between the drive gear 19 and the first one-way gear 18, the first transmission shaft 2 rotates counterclockwise. This causes each filter frame 6 to rotate counterclockwise synchronously through the sliding sleeve 3. Through reverse centrifugal force, the impurities filtered inside the filter frame 6 are discharged in the opposite direction to the top of the linkage disk 4. Since the bottom of the filter frame 6 is still inside the opening 5, the linkage disk 4 rotates accordingly. During this process, the impurities on the top of the linkage disk 4 are thrown to the edge of the linkage disk 4. The above operation is repeated to process the floating impurities multiple times.

[0050] The extension mechanism includes a guide plate 8 installed at the bottom of the filter frame 6 and an adjustment assembly for driving the guide plate 8 to rotate. The adjustment assembly includes a plurality of fixed cylinders 25 hinged to the bottom of one side of the filter frame 6 and a slide rod 26 slidably connected inside the fixed cylinders 25. The top of the guide plate 8 is hinged to the bottom of the other side of the filter frame 6. The bottom end of the slide rod 26 is hinged to the bottom of the guide plate 8. A spring 27 is fixedly connected to the inner wall of the top of the fixed cylinder 25, and the bottom end of the spring 27 is fixedly connected to the top end of the slide rod 26.

[0051] When the guide plate 8 is located inside the opening 5, the guide plate 8 is in a vertical state due to the limiting effect of the opening 5. As the filter frame 6 moves downward, the guide plate 8 moves out of the opening 5. Through the rebound force of the spring 27, the slide rod 26 moves towards the outside of the fixed cylinder 25, thereby driving the guide plate 8 to rotate with its top as the center, so that the guide plate 8 is in an inclined state. When the stirring mechanism drives the raw material to rotate counterclockwise, the raw material in the top area will enter the filter frame 6 along the guide plate 8, increasing the range of raw material filtration and impurity removal, and improving the thoroughness of impurity removal.

[0052] When the filter frame 6 moves upward, it drives the guide plate 8 to move upward simultaneously. When the guide plate 8 comes into contact with the lower edge of the opening 5, the guide plate 8 gradually rotates back to a vertical state and enters the interior of the opening 5.

[0053] A dust extraction pipe 24 is installed on the outer wall of the other side of the fermentation tank 1. A control valve is installed on the dust extraction pipe 24. The dust extraction pipe 24 is located on the top of the linkage plate 4 and is connected to the dust collection equipment.

[0054] After the impurities at the top of the linkage disk 4 are thrown to the edge of the linkage disk 4, the impurities at the edge of the linkage disk 4 are sucked away through the impurity suction pipe 24.

[0055] A probiotic-based grain fermentation method, employing the aforementioned probiotic-based grain fermentation apparatus, includes the following steps:

[0056] S1. Add the raw materials required for fermentation into the fermentation tank 1 through the feeding cylinder 9;

[0057] S2. By controlling the first motor 16 to drive the linkage shaft 12 to rotate counterclockwise, the second transmission shaft 13 rotates synchronously, thereby driving each stirring blade 14 to stir the raw materials inside the fermentation tank 1, where lighter impurities will float to the surface.

[0058] S3. By controlling the second motor 17 to drive the drive gear 19 to rotate counterclockwise, the meshing action between the drive gear 19 and the second one-way gear 23 drives the driven shaft 20 to rotate. When the driven shaft 20 rotates, it drives the reciprocating screw 21 to rotate synchronously, causing the lifting block 22 to move down from the top end of the reciprocating screw 21 to its bottom end. This causes the sliding sleeve 3 to move down synchronously along the outer wall of the first transmission shaft 2, and each filter frame 6 moves down along the inner wall of the opening 5, so that the lower edge of the filter frame 6 moves down below the liquid level, and the upper edge of the filter frame 6 moves down to the bottom. Above the liquid level, and simultaneously, after the guide plate 8 moves out of the interior of the inlet 5, the spring 27 rebounds and drives the slide rod 26 to move towards the outside of the fixed cylinder 25, thereby driving the guide plate 8 to rotate with its top as the center, so that the guide plate 8 is in an inclined state. When the stirring mechanism drives the raw material to rotate counterclockwise, the raw material in the top area will enter the interior of the filter frame 6 along the guide plate 8, increasing the range of raw material filtration and impurity removal, and improving the thoroughness of impurity removal. When impurities pass through the interior of the filter frame 6, they are filtered inside the filter frame 6 by the filter screen 7.

[0059] S4. By controlling the second motor 17 to drive the reciprocating screw 21 to continue rotating, the lifting block 22 is moved from the bottom end of the reciprocating screw 21 to its top end, thereby driving the filter frame 6 to move up and reset through the sliding sleeve 3, so that the inner wall of the bottom of the filter frame 6 is at the same level as the top of the linkage disk 4. Then, the second motor 17 is controlled to drive the drive gear 19 to rotate clockwise. Through the meshing action between the drive gear 19 and the first one-way gear 18, the first transmission shaft 2 is driven to rotate counterclockwise, thereby driving each filter frame 6 to rotate counterclockwise synchronously through the sliding sleeve 3. Through the reverse centrifugal force, the impurities filtered inside the filter frame 6 are discharged in the reverse direction to the top of the linkage disk 4. Since the bottom of the filter frame 6 is still inside the opening 5, the linkage disk 4 rotates accordingly. In this process, the impurities on the top of the linkage disk 4 are thrown to the edge of the linkage disk 4.

[0060] S5. After the impurities at the top of the linkage disk 4 are thrown to the edge of the linkage disk 4, the impurities at the edge of the linkage disk 4 are sucked out through the impurity suction pipe 24.

[0061] S6. Repeat the operations of S3-S4 to process the floating impurities multiple times. After fermentation is completed, control the solenoid valve 11 to open and discharge the material inside the fermentation tank 1 through the discharge pipe 10.
