Description

Technical Field

[0001] The present invention relates to the technical field of fermentation equipment, in particular to microbial fermentation equipment and a fermentation process. Background Art

[0002] Microbial fermentation is a biotechnological process that uses the metabolic activity of microorganisms to convert raw materials into useful products. It is widely used in a variety of fields, including food, beverages, pharmaceuticals, chemicals, and biofuels. The core of microbial fermentation is the utilization of microbial metabolic activity. Under suitable environmental conditions, microorganisms break down organic matter to generate energy and synthesize metabolic products. Fermentation equipment provides a suitable environment for microbial fermentation.

[0003] When existing fermentation equipment stirs multiple raw materials, waste residue will be generated during the stirring and fermentation process because the raw materials of the fermented product include multiple solid and liquid raw materials.

This not only increases the entire production process, but also reduces the fermentation efficiency of the fermented product. Summary of the Invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. First, the gap between the moving ring and the truncated pedestal is opened by the blocking mechanism, and the blocking mechanism and the stirring mechanism are moved upward, so that the raw materials flow into the gap between the moving ring and the inner bottom surface of the fermentation tank body. Then, the moving ring, the truncated pedestal, and the blocking mechanism are combined to form a piston and moved downward, and the raw materials below it are pressed into two filter boxes for filtration. This can separate the waste residue generated during the fermentation process, reduce the subsequent procedures, and improve the fermentation efficiency of the fermented products.

[0023] 2. When the raw materials enter the water inlet pipe, filter box and outlet pipe, the increase in pressure will accelerate the mixing of various raw materials. As the raw materials fall into the fermentation tank again, the raw materials will vibrate and generate water columns to break up the solid raw materials in the raw materials, which will also accelerate the mixing of the raw materials, thereby further improving the fermentation efficiency.

[0024] 3. Connect the metal tube to the air pipe of the external air pump through a rotary joint, and inflate the metal tube and spray it out from multiple nozzles to generate air columns. This can separate the waste residue and residual solid raw materials adsorbed on the filter plate from the filter plate to avoid clogging the filter plate, and can accelerate the mixing of the residual solid raw materials with the raw materials in the filter box;

[0025] 4. The metal tube can be rotated by the drive of motor 1, which can make the air column clean the filter plate intermittently, thereby intermittently impacting the filter plate and extending the service life of the filter plate;

[0026] 5. The elastic rope provides tension to the water outlet pipe. Under the elastic action of the elastic rope itself, the tension of the elastic rope will decrease and begin to shrink during the upward movement of the cylindrical shell, so that a part of the water outlet pipe is still suspended high by the elastic rope, thereby preventing the rotation of the stirring blade from winding up and tearing the water outlet pipe.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1 - Figure 9In an embodiment of the present invention, a microbial fermentation device includes a fermentation tank body 1 and a stirring mechanism 2. The stirring mechanism 2 is arranged inside the fermentation tank body 1, and a blocking mechanism 3 is provided on the inner side of the stirring mechanism 2. Two symmetrical filtering mechanisms 4 are fixedly connected to the top of the outer wall of the fermentation tank body 1. The stirring mechanism 2 includes a stirring rod 21 that rotates through the top surface of the fermentation tank body 1, and a plurality of stirring blades 22 are fixedly connected to the bottom end of the outer wall of the stirring rod 21 at equal angles. A movable ring 23 is fixedly connected between the bottom ends of the plurality of stirring blades 22. The bottom end of the stirring rod 21 is fixedly connected to a truncated table seat 24. The outer wall of the stirring rod 21 is rotatably connected to a cylindrical shell 25. A cavity is opened inside the stirring rod 21 and corresponds to the cylindrical shell 25. The cylindrical shell 2 5 is communicated with the interior of the cavity, and a plurality of circular tubes 26 fixedly connected to the stirring blades 22 at corresponding positions are fixed at an annular and equiangular position on the outer wall of the stirring rod 21 at corresponding positions. The outer wall of the circular tube 26 is penetrated by a plurality of through holes, and the filtering mechanism 4 includes a filter box 41 fixedly connected to the outside of the fermentation tank body 1, and a filter plate 42 is detachably connected to the inside of the filter box 41. The top surface of the filter box 41 is penetrated by a water inlet pipe 411 fixed to the bottom surface of the fermentation tank body 1, and the bottom surface of the filter box 41 is penetrated by a water outlet pipe 412 fixed to the top of the side surface of the fermentation tank body 1 and fixed to the inside of the cylindrical shell 25. An anti-blocking component 43 for cleaning the filter plate 42 is provided inside the filter box 41 and below the filter plate 42.

[0039] Specifically, first, a variety of raw materials are poured into the fermentation tank body 1 in a certain proportion, and then the stirring rod 21 drives the multiple stirring blades 22 and the blocking mechanism 3 to rotate. The rotating stirring blades 22 can stir the multiple raw materials so that the multiple raw materials are mixed. After stirring for a period of time, the gap between the movable ring 23 and the pedestal seat 24 is exposed by the driving of the blocking mechanism 3. At the same time, the stirring rod 21 moves upward, so that the movable ring 23, the pedestal seat 24, the stirring blades 22 and the blocking mechanism 3 move upward and away from the inner bottom surface of the fermentation tank body 1. At this time, the multiple raw materials originally above the movable ring 23 flow downward from the gap between the movable ring 23 and the pedestal seat 24 under the action of their own gravity until the movable ring 23 moves up to The highest position (the moving ring 23 is located above the various raw materials), and then the gap between the moving ring 23 and the pedestal seat 24 is blocked by the driving of the blocking mechanism 3, and the moving ring 23, the pedestal seat 24, the stirring blade 22 and the blocking mechanism 3 are moved down until they are restored to their original positions. At this time, the moving ring 23, the pedestal seat 24 and the blocking mechanism 3 form a structure similar to a piston, and the various raw materials are respectively introduced into the filter box 41 at the corresponding positions through the two water inlet pipes 411, and are filtered through the filter plate 42 to separate the waste residues generated by the various raw materials during the fermentation process from the various raw materials. As the moving ring 23, the pedestal seat 24, and the blocking mechanism 3 move downward, the pressure in the filter box 41 will increase, and then enter through the outlet pipe 412 The raw materials in the fermentation tank body 1 are compressed and discharged from the exhaust system of the fermentation tank body 1, so that the raw materials in the fermentation tank body 1 can be normally pressed into the filter box 41. At this time, the rotation of the stirring blade 22 can continue to stir the raw materials above it, and as more and more raw materials fall on the moving ring 23, the pedestal seat 24 and the blocking mechanism 3, a part of the circular tubes 26 will be located in the plurality of raw materials. The raw materials are then ejected from the through-holes, and the generated water column can break up the solid raw materials in the various raw materials (since the solid raw materials become loose after being soaked in liquid, when the water column washes over the loose solid raw materials, the loose solid raw materials will be impacted and broken, such as rainwater washing the soil to produce mudslides), so that the various raw materials can be mixed together more quickly. Since part of the solid raw materials will be separated together with the waste residue in the process of filtering the waste residue, the waste residue and solid raw materials adsorbed on the filter plate 42 can be separated from the filter plate 42 by driving the anti-blocking component 43. Moreover, when the movable ring 23, the pedestal seat 24 and the sealing mechanism 3 move downward, the filter box 41 will be continuously filled with raw materials.Therefore, the solid raw materials remaining on the filter plate 42 will be mixed with the raw materials poured into the filter box 41 (due to the fermentation of multiple raw materials, the multiple raw materials used can be dissolved in each other, similar to sugar and salt dissolving in water. After complete dissolution, there will be no solid raw materials, but waste residue will be produced after the fermentation reaction of multiple raw materials). Therefore, only fermented waste residue will remain on the filter plate 42. After the multiple raw materials are completely fermented, the staff can stop the equipment and discharge the fermented raw materials through the discharge pipe on the fermentation tank body 1, and then remove the filter plate 42 from the filter box 41 at the corresponding position and clean up the waste residue (according to, Figure 1 and Figure 2 It can be seen that the filter box 41 is similar to a cabinet with a door. The device first opens the gap between the movable ring 23 and the truncated pedestal 24 through the sealing mechanism 3, and moves the sealing mechanism 3 and the stirring mechanism 2 upward, so that the raw materials flow into the space between the movable ring 23 and the inner bottom surface of the fermentation tank body 1. Then, the movable ring 23, the truncated pedestal 24, and the sealing mechanism 3 are combined to form a piston and moved downward, and the raw materials below it are pressed into the two filter boxes 41 for filtration. The waste residue generated during the fermentation process can be separated, the subsequent procedures can be reduced, and the efficiency of fermentation of the fermented material can be improved. As the raw materials enter the water inlet pipe 411, the filter box 41 and the water outlet pipe 412, the increase in pressure will accelerate the mixing of multiple raw materials. As the raw materials fall into the fermentation tank body 1 again, the raw materials will vibrate, and a water column will be generated to break the solid raw materials in the raw materials, which will also accelerate the mixing between the raw materials, thereby further improving the fermentation efficiency.

[0040] Example 1

[0041] like Figure 7-Figure 9 As shown, in this embodiment, the interior of the filter box 41 is fixedly connected to two symmetrical stabilizing frames 413, the anti-blocking component 43 includes a metal tube 431 rotatably connected between the two stabilizing frames 413, the outer wall of the metal tube 431 is fixedly connected to multiple nozzles 432 at equal intervals, the top of the outer wall of the fermentation tank body 1 is rotatably connected to the ring gear 11, the outer wall of the fermentation tank body 1 is fixedly connected to a fixing plate, the top surface of the fixing plate is fixedly connected to a motor 12, the output end of the motor 12 is fixedly connected to a spur gear 13 meshing with the ring gear 11, the metal tube 431 is fixedly connected to the outer wall of the fermentation tank body 1 One end passes through the side of the filter box 41 and is fixedly connected to bevel gear three 433. The side of the filter box 41 is fixedly connected to a connecting block 414. The top surface of the connecting block 414 passes through a connecting shaft 434 for rotation. The bottom end of the outer wall of the connecting shaft 434 is fixedly connected to a bevel gear four 435 that meshes with the bevel gear three 433 at the corresponding position. The top end of the outer wall of the connecting shaft 434 is fixedly connected to a spur gear two 436 that meshes with the ring gear 11. The top surface of the filter box 41 passes through an air outlet pipe that passes through the fermentation tank body 1, and the outer wall of the air outlet pipe is fixedly connected to a pressure relief valve.

[0042] In this embodiment, the metal tube 431 is first connected to the air pipe of the external air pump through a rotary joint, and the ring gear 11 can be rotated by the drive of the motor 12. The rotating ring gear 11 can rotate the two spur gears 2 436, and the rotating spur gears 2 436 can rotate the metal tube 431 at the corresponding position through the bevel gear 3 433 and the bevel gear 4 435 at the corresponding position. At the same time, the operation of the air pump can inflate the metal tube 431 and spray it from the multiple nozzles 432 to generate an air column (inert gas or oxygen gas can be injected into the metal tube 431 according to the fermentation environment in the fermentation tank body 1). The waste residue and residual solid raw materials adsorbed on the filter plate 42 are separated from the filter plate 42 to avoid clogging the filter plate 42, and the residual solid raw materials can be accelerated to mix with the raw materials in the filter box 41 (the generation of the air column can accelerate the flow of the raw materials in the filter box 41). Through the rotation of the metal tube 431, the filter plate 42 can be intermittently cleaned, thereby intermittently impacting the filter plate 42, thereby extending the service life of the filter plate 42. The gas in the filter box 41 can be injected into the fermentation tank body 1 through the outlet pipe and the pressure relief valve, and then sprayed out from the air outlet of the fermentation tank body 1, thereby relieving the pressure in the filter box 41.

[0043] Example 2

[0044] like Figure 2 、 Figure 3 and Figure 7 As shown, in this embodiment, the water outlet pipe 412 is a hose, and two symmetrical L-shaped plates 15 are fixedly connected to the top of the outer wall of the fermentation tank body 1. The inner top surface of the L-shaped plate 15 is fixedly connected to the elastic rope 16, and the elastic rope 16 is connected to the water outlet pipe 412 at the corresponding position through a ring.

[0045] In this embodiment, since the water outlet pipe 412 is connected to the cylindrical shell 25, when the stirring rod 21 moves, it will drive the cylindrical shell 25 to move together. In order to prevent the rotation of the stirring blades 22 from rolling up the water outlet pipe 412 when multiple stirring blades 22 move to the highest point, the end of the water outlet pipe 412 will also move up when the stirring rod 21 drives the cylindrical shell 25 to move upward. At this time, the tension of the elastic rope 16 will decrease and begin to shrink, so that a part of the water outlet pipe 412 is still suspended high by the elastic rope 16, thereby preventing the rotation of the stirring blades 22 from rolling up the water outlet pipe 412 and tearing it apart.

[0046] Example 3

[0047] like Figure 4 and Figure 5As shown, in this embodiment, the top end of the outer wall of the stirring rod 21 is fixedly connected to a bevel gear 1 211, the top surface of the fermentation tank body 1 is provided with a motor 27, the output end of the motor 27 is fixedly connected to a bevel gear 271 meshing with the bevel gear 1 211, the outer wall of the fermentation tank body 1 is fixedly connected to a fixed ring 14, the top surface of the fermentation tank body 1 is provided with a movable plate 28 fixedly connected to the bottom surface of the motor 27 and rotating through the stirring rod 21, an electric push rod 1 281 is fixedly connected between the two ends of the bottom surface of the movable plate 28 and the fixed ring 14, the top surface of the movable ring 23 is an inverted frustum structure inclined toward the middle, and the top surface of the cylindrical shell 25 is fixedly connected to two symmetrical sliding rods 251 that slide through the top surface of the fermentation tank body 1.

[0048] In this embodiment, the two electric push rods 281 drive the movable plate 28 to drive the motor 27 and the stirring rod 21 to move, so that the raw materials can flow under the movable ring 23, and then the movable ring 23, the pedestal seat 24 and the blocking mechanism 3 are moved downward to apply pressure to the raw materials, so that the raw materials enter the filter box 41 for filtration.

[0049] Example 4

[0050] like Figure 6 As shown, in this embodiment, the inner side surface of the stirring blade 22 is fixedly connected with a vertically downward sliding rod 1 221, the top surface of the movable plate 28 is fixedly connected with an L-shaped plate 282, the bottom end of the stirring rod 21 is provided with a groove, and the outer wall bottom end of the stirring rod 21 is provided with a plurality of sliding holes connected to the inside of the groove at an annular equal angle. The blocking mechanism 3 includes a round rod 31 that slides through the stirring rod 21, and the corresponding sliding holes at the bottom end of the outer wall of the round rod 31 are fixedly connected with a fixing frame 32 that slides through the sliding holes at the corresponding positions. The bottom ends of the multiple fixing frames 32 are fixedly connected with a plug 33, and the inner top surface of the L-shaped plate 282 is fixedly connected with an electric push rod 2 34. The round rod 31 is rotatably connected to the output end of the electric push rod 2 34 through a connecting piece.

[0051] In this embodiment, the movement of the plug 33 can be controlled by driving the electric push rod 23. The upward movement of the plug 33 can expose the gap between the movable ring 23 and the pedestal seat 24, so that the raw materials can flow between the movable ring 23 and the inner bottom surface of the fermentation tank body 1. By blocking the gap with the plug 33, the raw materials can be prevented from overflowing from the gap between the movable ring 23 and the pedestal seat 24 and releasing pressure when the raw materials are pressed into the filter box 41.

[0052] A fermentation process comprises the following steps:

[0053] Step 1: Loading and starting the equipment: Pour a certain proportion of various raw materials into the fermentation tank body 1, set the internal fermentation environment through the fermentation tank body 1, and stir the various raw materials through the stirring mechanism 2;

[0054] Step 2, filtration stage: Through the cooperation of the blocking mechanism 3 and the stirring mechanism 2, the various raw materials in the fermentation tank body 1 are pressed into the two filtering mechanisms 4 for filtration. The pressure in the filtering mechanisms 4 increases, causing the raw materials to flow back into the fermentation tank body 1 and generate oscillations. This step is repeated multiple times.

[0055] Step 3, discharging stage: the equipment is powered off and stopped, and the raw materials after fermentation are discharged through the discharge pipe on the fermentation tank body 1.
