[0037] Example 1

[0038] like Figure 1-Figure 4 As shown, the present invention provides a microbial fermentation tank, including: a substrate barrel 2, which is rotatably arranged on a fermentation tank body 1, on which a first filter layer 201 is provided, and a substrate tank movable opening 202 is provided at an end thereof, and the interior of the substrate barrel 2 is connected with the interior of the fermentation tank body 1 through the first filter layer 201; a substrate tank 3, which can be slidably inserted into the substrate barrel 2 and rotates with the substrate barrel 2, on which a second filter layer 301 is provided, in which a fermentation substrate is contained, and the interior of the substrate tank 3 is connected with the interior of the substrate barrel 2 through the second filter layer 301; a rotation drive device 4, used to drive the substrate barrel 2 to rotate; a telescopic drive device 5, used to drive the substrate tank 3 to slide into or out of the substrate tank movable opening 202.

[0039] Specifically, the fermentation tank body 1 is placed vertically. The substrate cylinder 2 is arranged horizontally on the upper part of the fermentation tank body 1, penetrates the fermentation tank body 1 and extends outward at both ends. One end of the substrate cylinder 2 is closed and the other end is open. The open end is the substrate tank movable opening 202. The substrate tank 3 can be slidably inserted in the substrate cylinder 2. When the telescopic driving device 5 controls the substrate tank 3 to be pulled out of the substrate cylinder 2 (such as Figure 1 As shown), add or take out the fermentation substrate into the substrate tank 3. After the addition is completed, the telescopic drive device 5 controls the substrate tank 3 to be inserted into the substrate cylinder 2 (as shown in FIG. Figure 2 As shown in the figure, the substrate cylinder 2 is driven to rotate by the rotation drive device 4, thereby driving the substrate tank 3 to rotate, and the fermentation substrate in the substrate tank 3 is turned over accordingly, which has the effect of turning over the fermentation substrate. The fermentation tank body 1 contains fermentation liquid for soaking the fermentation substrate, and the height of the fermentation liquid at least exceeds the substrate cylinder 2, so as to enter the fermentation tank through the first filter layer 201 and the second filter layer 301 to soak the fermentation substrate in the substrate tank 3. The first filter layer 201 and the second filter layer 301 allow the fermentation liquid in the fermentation tank body 1 to enter the substrate tank 3 on the one hand, and prevent the fermentation substrate in the substrate tank 3 from being mixed into the fermentation tank on the other hand.

[0040] The rotation drive device 4 can be driven by a motor (gear meshing drive or pulley transmission drive, etc.) or a crank connecting rod drive, and the telescopic drive device 5 can be driven by a hydraulic drive, a screw drive, a worm drive, etc.

[0041] Since the device utilizes the dead weight of the fermentation substrate to turn over in the substrate tank 3, there is no need to use a stirring rod for vigorous stirring, so the fermentation substrate will not be broken up. Moreover, since the fermentation substrate with a larger volume cannot pass through the first filter layer 201 and the second filter layer 301, it will not enter the fermentation tank body 1 and mix with the fermentation liquid, causing the loss of the fermentation substrate, thereby saving production costs.

[0042] Example 2

[0043] This embodiment 2 specifically describes the technical solution of the substrate tank 3 to prevent the fermentation substrate from being compacted.

[0044] like Figure 1-Figure 3 As shown, a cross bar 302 is provided inside the substrate tank 3, a fixed portion of the telescopic drive device 5 is provided on one side of the fermentation tank body 1, and one end of the cross bar 302 extends out of the substrate tank 3 and is connected to the movable portion of the telescopic drive device 5. The cross bar 302 is hollow inside to form a cavity 303, and a plurality of protruding covers 304 are connected to the cross bar 302, the interior of the protruding covers 304 is hollow and communicates with the cavity 303, a plurality of through holes 305 are provided on the protruding covers 304 and the cross bar 302, and the protruding covers 304 and the cross bar 302 are covered with a third filter layer 306, and the interior of the protruding covers 304 and the cross bar 302 is communicated with the interior of the substrate tank 3 through the third filter layer 306.

[0045] Specifically, a cross bar 302 is fixedly passed through the substrate tank 3 along its sliding / extension direction, and one end of the cross bar 302 close to the substrate tank movable opening 202 extends out of the substrate tank 3 and is connected to a first connecting piece 501, while the other end of the first connecting piece 501 is connected to the movable end of the telescopic driving device 5. When the telescopic driving device 5 performs a telescopic action, the substrate tank 3 is driven to extend / retract into the substrate tube 2 through the first connecting piece 501 and the cross bar 302.

[0046] Compared with the method of turning the material by using a stirring rod, since the present device turns the material by using the dead weight of the fermentation substrate, the weight of all the fermentation substrates gradually accumulates from high to low, and the fermentation substrate at the bottom is subjected to the greatest pressure, and will be pressed more tightly, so that it cannot be well contacted with the fermentation liquid. When the present device sets a cross bar 302 in the middle of the fermentation tank, the cross bar 302 can share the pressure of a large amount of fermentation substrates to avoid material compaction. And because the cavity 303 in the cross bar 302 and the raised cover 304 on the cross bar 302 allow the fermentation liquid to enter therein, the central part of the fermentation substrate is also in contact with the fermentation liquid during the soaking process, thereby improving the fermentation effect.

[0047] Example 3

[0048] This embodiment 3 specifically describes the technical solution of how the fermentation tank body 1 drains liquid.

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, a bottom box 7 is provided below the fermentation tank body 1, a funnel-shaped discharge port 101 is provided at the bottom of the fermentation tank body 1, the bottom of the fermentation tank body 1 is liftably connected to the top of the bottom box 7, and a discharge port 701 is provided on one side of the bottom box 7. A lifting drive device 6 is provided between the bottom box 7 and the fermentation tank body 1, and the lifting drive device 6 is used to drive the fermentation tank body 1 to rise and fall relative to the bottom box 7. A sealing layer 102 is provided at the bottom end of the funnel-shaped discharge port 101, and the sealing layer 102 is sealed against the bottom box 7. A feed inlet 103 is provided on the fermentation tank body 1.

[0050] Specifically, a feed inlet 103 is fixedly provided at the top of the fermentation tank body 1, and a cover body 104 is threadedly connected to the feed inlet 103, and fermentation liquid is added to the fermentation tank body 1 through the feed inlet 103. A plug-in interface is provided at the middle of the top of the bottom box 7, and the lower part of the fermentation tank body 1 can be slidably plugged into the plug-in interface, and a rubber ring for sealing is provided between the fermentation tank body 1 and the plug-in interface; the bottom of the fermentation tank body 1 is a funnel-shaped discharge port 101, and the discharge bottom end of the funnel-shaped discharge port 101 is abutted and sealed with the inner wall of the bottom box 7 through a sealing layer 102, and the sealing layer 102 can be a rubber ring that fits the discharge bottom end edge of the funnel-shaped discharge port 101.

[0051] The two sides of the fermentation tank are respectively connected to the second connecting piece 601, and two telescopic drive devices 5 are respectively fixed to the two sides of the top of the bottom box 7, and the movable ends of the two telescopic drive devices 5 are respectively provided with the second connecting piece 601 to connect with the fermentation tank body 1. Figure 4 As shown in the figure, when the telescopic drive device 5 extends, the fermentation tank body 1 rises, and the discharge bottom end of the funnel-shaped discharge port 101 is separated from the bottom box 7, and the fermentation liquid in the fermentation tank body 1 is discharged into the bottom box 7 and discharged from the discharge port 701 provided on the bottom box 7. A valve 702 is provided on the discharge port 701 for control. Figure 1 and Figure 2 When the telescopic drive device 5 is retracted, the fermentation tank body 1 falls, and the discharge bottom end of the funnel-shaped discharge port 101 is abutted and sealed with the bottom box 7, and the fermentation liquid is stored in the fermentation tank body 1. The volume of the bottom box 7 is the same as that of the fermentation tank body 1.

[0052] Example 4

[0053] This embodiment 4 specifically describes the technical solution of how the substrate tank 3 rotates.

[0054] like Figure 2 As shown, the rotation driving device 4 includes a driving motor 401, which is fixedly arranged on the fermentation tank body 1. A driven member 403 is arranged outside the substrate cylinder 2. The driving motor 401 drives the substrate cylinder 2 to rotate by driving the driven member 403. The inner wall section of the substrate cylinder 2 is a polygon, and the outer wall section of the substrate tank 3 is a polygon matching the inner wall section of the substrate cylinder 2.

[0055] Specifically, the driving motor 401 is arranged on one side of the fermentation tank body 1, and is connected to a driving gear 402. The substrate barrel 2 is provided with a driven gear that meshes with the driving gear 402. The driving motor 401 drives the entire substrate barrel 2 to rotate through the driving gear 402 and the driven gear. During the rotation of the substrate barrel 2, the polygonal fitting structure between the substrate barrel 2 and the substrate tank 3 drives the substrate tank 3 to rotate, thereby realizing that the substrate tank 3 and the substrate barrel 2 can be slidably connected and can rotate synchronously. The inner wall section of the substrate barrel 2 is polygonal, and the outer section is circular.

[0056] On both sides of the substrate tank 3 are two polygonal blocks 307 that can fit into the substrate cylinder 2. The crossbar 302 runs through the two polygonal blocks 307 and fixes the distance between them. The distance between the two polygonal blocks 307 is the fermentation substrate volume of the substrate tank 3. The two polygonal blocks 307 include a rubber layer 308 for connection and sealing. The second filter layer 301 is arranged on the rubber layer 308 at a position corresponding to the substrate holding chamber formed between the two polygonal blocks 307, so that the fermentation liquid can enter the substrate tank 3. The distance between the two polygonal blocks 307 is greater than the length of the first filter layer 201.

[0057] Example 5

[0058] like Figure 1 As shown, a temperature control device 8 and a humidity control device 9 are provided on the fermentation tank body 1 .

[0059] Specifically, the temperature control device 8 and the humidity control device 9 are respectively located at both sides of the top of the fermentation tank body 1 and are connected to the inside of the fermentation tank body 1 to control the temperature and humidity in the fermentation tank body 1 to ensure the fermentation environment conditions.

[0060] The principle of this device:

[0061] When using (such as Figure 1 Then, the substrate to be fermented (e.g., tobacco leaves) is placed in the substrate tank 3, and then (e.g., Figure 2 The state shown in the figure) is shortened by the telescopic driving device 5, driving the substrate tank 3 to move toward the substrate cylinder 2 until one end of the cross bar 302 is in contact with the inner wall of the substrate cylinder 2. Figure 1The state shown in the figure is then added into the fermentation tank body 1 through the feed port 103. At this time, the bottom end of the fermentation tank body 1 effectively seals through the setting of the sealing rubber, so that the added water is stored in the fermentation tank body 1, and the added water needs to cover the substrate tube 2, so that the fermented substrate can be effectively soaked.

[0062] The temperature inside the fermentation tank body 1 is then controlled by the temperature control device 8 , while the humidity inside the fermentation tank body 1 is controlled by the humidity control device 9 .

[0063] After a period of time, the temperature reaches the required value, and then the microorganisms are added into the fermentation tank body 1 from the feed port 103. At this time, the cover body 104 is covered to replenish air at a constant temperature and humidity, and the fermentation substrate is stirred for fermentation. When the fermentation substrate is stirred, the rotation drive device 4 is started to operate, driving the substrate barrel 2 to rotate, and then the substrate tank 3 is driven to rotate synchronously through the polygonal structure of the substrate barrel 2 and the substrate tank 3. In this way, during the rotation of the substrate tank 3, the fermentation substrate placed inside the substrate tank 3 is shaken and loosened, which makes it easier for the microorganisms to penetrate into the middle of the fermentation substrate, and the multiple raised cover bodies 304 provided in the substrate tank 3 can effectively prevent the compaction of the fermentation substrate from affecting the fermentation, and the device is arranged in this way, which can not only effectively play a stirring role, but also effectively avoid the generation of a large amount of fermentation substrate debris during the stirring process.

[0064] After fermentation is complete, Figure 4 The lifting drive device 6 is started to extend and operate, driving the fermentation tank body 1 to move upward, thereby making the bottom end of the fermentation tank body 1 separate from the bottom surface of the bottom box 7. At this time, the liquid in the fermentation tank body 1 flows into the bottom box 7, and at the same time, the substrate tank 3 rotates, so that the fermentation substrate in the substrate tank 3 rotates synchronously. Under the action of centrifugal force, the liquid inside the fermentation substrate is thrown onto the inner wall of the fermentation tank body 1, and the liquid then rolls along the inner wall of the fermentation tank body 1 into the bottom box 7. This arrangement can effectively separate the fermentation substrate and the liquid.

[0065] Then, the telescopic driving device 5 is extended to make the substrate tank 3 slide out of the substrate tube 2 to clean out the substrate, and the liquid in the bottom box 7 is discharged through the discharge port 701 for collection.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
