[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0029] like Figure 1 As shown, the embodiment of the present application provides an aerobic solid-state fermentation barrel, which includes a barrel body 101 and a barrel cover 301. The barrel body 101 is used to contain aerobic solid-state fermentation raw materials. A large amount of oxygen is required during the fermentation process of the raw materials. The sterile air system outside the barrel body 101 transports the output sterile air along the barrel body 101 to the inside of the fermentation barrel to meet the fermentation requirements of the raw materials.
[0030] Furthermore, as sterile air continuously enters the barrel body 101, in order to ensure the stability of the air pressure inside the barrel body 101, the air needs to be discharged from the barrel body 101. Specifically, the air can be discharged from the barrel body 101 along the barrel cover 301. At the same time, the unsterilized air in the external environment may also enter the barrel body 101 along the barrel cover 301. In order to prevent the air from bringing bacteria into the barrel body 101, the barrel cover 301 is provided with an air filter structure 302, thereby isolating the bacteria outside the fermentation barrel to ensure the normal aerobic fermentation of the raw materials.
[0031] In some examples, the barrel 101 is provided with an air intake assembly, which is used to introduce external sterile air into the barrel 101. The air intake assembly is arranged at the bottom of the barrel 101, and the sterile air enters from the bottom of the barrel 101 and is discharged from the barrel cover 301 at the top of the barrel 101. It can be understood that one end of the air intake assembly is connected to the sterile air system, and the other end is connected to the internal space of the barrel 101.
[0032] like Figure 2 As shown, in some examples, the air intake assembly includes an air distributor 201. When sterile air is introduced into the barrel body 101, the sterile air enters the barrel body 101 along the air distributor 201. The air distributor 201 facilitates the sterile air to be evenly distributed throughout the barrel body 101.
[0033] Furthermore, the air distributor 201 is provided with a plurality of channels, one end of the channel is connected to the internal space of the air distributor 201, and the other end of the channel is connected to the internal space of the barrel body 101, so that the sterile air is first transported to the interior of the air distributor 201, and then enters the barrel body 101 along the channel, thereby contacting the aerobic solid fermentation raw materials.
[0034] The channels include hollow structures such as through holes, and the channels are approximately evenly distributed on the air distributor 201 to ensure that the amount of sterile air entering the barrel 101 from each position of the air distributor 201 is approximately equal. At the same time, the air distributor 201 is fixedly connected to the bottom of the barrel 101 so that the air distributor 201 and the barrel 101 form a whole, thereby preventing the air distributor 201 from frequently touching the inner wall of the barrel 101 during transportation of the fermentation barrel, resulting in structural damage.
[0035] Specifically, the air distributor 201 at the bottom of the barrel 101 is configured as a spiral tube structure. When the barrel 101 is roughly formed as a cylinder, the bottom of the barrel 101 is circular, and the spiral shape can be approximately evenly distributed at various positions of the circular bottom. Combined with the uniform layout of the channels, it can better ensure that sterile air evenly enters the barrel 101. One end of the tube structure is closed and located at the center of the bottom of the barrel 101. The tube structure gradually expands outward from the center of the bottom of the barrel 101 in a rotating manner.
[0036] In addition, in order to prevent the air distributor 201 from rusting in a relatively humid environment, the air distributor 201 is made of stainless steel.
[0037] It is worth noting that during the fermentation of the raw materials, a certain amount of liquid may be formed. In order to prevent the liquid from entering the air distributor 201 along the channel and affecting the entry of sterile air, a positive pressure is maintained in the air distributor 201.
[0038] In some examples, in order to allow sterile air to enter the air distributor 201, the air intake assembly further includes an air intake pipe 202, one end of which is connected to the sterile air system, and the other end is connected to the air distributor 201. The sterile air enters the air distributor 201 along the air intake pipe 202, and then enters the barrel 101 from the air distributor 201.
[0039] Among them, the air distributor 201 is inside the barrel body 101, and the sterile air system is outside the barrel body 101, so the air inlet pipe 202 needs to pass through the barrel body 101 to achieve the connection between the two. On this basis, the barrel body 101 is provided with a sealing connection structure 203, and the sealing connection structure 203 defines a hole structure on the barrel body 101 for the air inlet pipe 202 to be inserted. When the air inlet pipe 202 is inserted into the barrel body 101 along the hole structure, the sealing connection structure 203 blocks the gap between the air inlet pipe 202 and the barrel body 101, preventing the sterile air from escaping along the gap, and also preventing the external air from bringing in miscellaneous bacteria along the gap.
[0040] Furthermore, the air inlet pipe 202 is made of soft material, and there is no need to limit the relative position between the sterile air system and the fermentation barrel, thereby improving versatility. Specifically, the air inlet pipe 202 is made of silicone material.
[0041] In some examples, the inner wall of the barrel body 101 is provided with a mixing structure 102. When the raw materials in the barrel body 101 clump during the fermentation process, the mixing structure 102 can cause the raw materials to form a loose state, making it easier for air to contact the raw materials evenly, which is beneficial to the fermentation process.
[0042] Furthermore, the mixing structure 102 is a rod-shaped structure and extends from the inner wall of the barrel body 101 to the middle of the barrel body 101. The barrel body 101 is made of thermoplastic fluoroplastic. Thermoplastic fluoroplastic is soft. When the raw materials in the barrel body 101 agglomerate, the barrel body 101 can be deformed inward by squeezing the barrel body 101 with external force. At this time, the mixing structure 102 contacts the raw materials and breaks up the raw materials.
[0043] In some examples, the outer wall of the barrel body 101 is provided with a recessed portion 103, and the recessed portion 103 forms a step structure on the outer wall of the barrel body 101. When the fermentation barrel is large in size and needs to be transported by a handling device, the handling device can be embedded in the recessed portion 103 and support the step structure to prevent the handling device from slipping on the outer wall of the barrel body 101. When the fermentation barrel is small in size and needs to be transported manually, the staff's hand extends into the recessed portion 103 and applies a supporting force to the step structure to prevent slipping.
[0044] It is understandable that a protrusion may also be provided on the outer wall, and the protrusion may also form a step structure on the outer wall of the barrel body 101, which is beneficial for the transportation of the fermentation barrel.
[0045] The barrel cover 301 is connected to the top opening of the barrel body 101, and the barrel cover 301 and the barrel body 101 are detachably connected. Since the gas inside the barrel body 101 needs to be discharged from the fermentation barrel along the barrel cover 301, a hollow structure 305 is provided on the barrel cover 301. It can be understood that the hollow structure 305 connects the internal space of the barrel body 101 with the external space, and the gas inside the barrel body 101 is discharged from the fermentation barrel along the hollow structure 305. Specifically, the barrel cover 301 is made of high temperature resistant and cost-effective polypropylene material.
[0046] Among them, the barrel body 101 and the barrel cover 301 are both resistant to high temperature and high pressure. Before the aerobic fermentation process of the raw materials, the barrel body 101 and the barrel cover 301 can be sterilized by high temperature and high pressure to avoid residual bacteria and ensure the smooth progress of the aerobic fermentation process.
[0047] Furthermore, external air may enter the barrel body 101 along the hollow structure 305, thereby bringing in miscellaneous bacteria and affecting the fermentation process of the raw materials. Therefore, the hollow structure 305 needs to be always within the range of the air filter structure 302, and at this time, the position of the air filter structure 302 on the barrel cover 301 needs to remain constant. In order to maintain the position of the air filter structure 302, an accommodating space is provided inside the barrel cover 301, and the air filter structure 302 is arranged in the accommodating space.
[0048] like Figure 3 As shown, in some examples, the barrel cover 301 includes an inner cover 303 and an outer cover 304 that are stacked, the inner cover 303 is connected to the top of the barrel body 101, and the outer cover 304 is connected to the top of the inner cover 303, so that the inner cover 303 is between the barrel body 101 and the outer cover 304. The area between the inner cover 303 and the outer cover 304 forms an accommodating space for arranging the air filter structure 302. Furthermore, the inner cover 303 and the outer cover 304 are detachably connected to facilitate the replacement of the air filter structure 302.
[0049] like Figure 5 As shown, in order to achieve a detachable connection between the inner cover 303 and the barrel body 101 , a first folded edge 306 is provided on the edge of the inner cover 303 . The first folded edge 306 extends toward the barrel body 101 and surrounds the outer wall of the barrel body 101 .
[0050] The inner edge of the first folded edge 306 is provided with a first internal thread 307 , and the outer wall of the barrel body 101 is provided with a first external thread. The first internal thread 307 and the first external thread are meshed with each other to form a detachable connection in a threaded connection manner.
[0051] like Figure 4 and Figure 5 As shown, in some examples, in order to achieve a detachable connection between the inner cover 303 and the outer cover 304, a second folded edge 309 is provided on the edge of the outer cover 304, and the second folded edge 309 extends toward the barrel body 101, and the size of the outer cover 304 is larger than that of the inner cover 303. When the outer cover 304 and the inner cover 303 are stacked, the second folded edge 309 surrounds the outside of the first folded edge 306.
[0052] The outer edge of the first folded edge 306 is provided with a second external thread 308, the second external thread 308 is located at the top of the first internal thread 307, the inner edge of the second folded edge 309 is provided with a second internal thread 310, the second internal thread 310 and the second external thread 308 are meshed with each other to form a detachable connection in a threaded connection. At this time, the air filter structure 302 is clamped between the inner cover 303 and the outer cover 304.
[0053] In some examples, a first sealing structure is provided between the inner cover 303 and the outer cover 304, and the first sealing structure blocks the gap between the inner cover 303 and the outer cover 304 to prevent external air from passing through the air filter structure 302 along the gap and entering the barrel body 101, thereby affecting the fermentation process of the raw materials.
[0054] At the same time, a second sealing structure is provided between the inner cover 303 and the barrel body 101, and the second sealing structure blocks the gap between the inner cover 303 and the barrel body 101 to prevent external air from entering the barrel body 101 along the gap through the air filter structure 302, thereby affecting the fermentation process of the raw materials.
[0055] It is worth noting that the first sealing structure and the second sealing structure cannot affect the gas inside the barrel 101 from being discharged to the fermentation barrel. Therefore, the first sealing structure and the second sealing structure need to avoid the hollow structure 305 on the premise of blocking the gap between the solid structures to ensure that the gas is unobstructed along the hollow structure 305 to be discharged from the barrel 101.
[0056] Specifically, the first sealing structure and the second sealing structure are made of silicone material, and the first sealing structure and the second sealing structure are both substantially formed in a ring shape.
[0057] In some examples, the air filter structure 302 includes a filter membrane, which is laid in the accommodating space. Further, when the first sealing structure is formed into a ring shape, the filter membrane extends to the inner edge of the first sealing structure and contacts it. This prevents external air from entering the barrel 101 through the gap between the filter membrane and the first sealing structure, causing raw material contamination.
[0058] In the description of this specification, if the reference terms "one embodiment", "some examples", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" appear, it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0059] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
