Description

Technical Field

[0001] This invention relates to the technical field of fermentation equipment. More specifically, this invention relates to a fermentation device for birch sap with antibacterial function. Background Technology

[0002] During birch sap fermentation, the sap needs to be stirred regularly to ensure fermentation effectiveness. However, when existing fermentation equipment stirs the birch sap, it causes the sap to slosh and splash onto the inner wall of the fermentation tank. As fermentation progresses, the viscosity of the birch sap increases (due to bacterial proliferation and accumulation of metabolic products), making the splashes more likely to adhere and form solid residues that are difficult to clean. Over time, mycelia will grow on these residues, and if they fall into the birch sap, cross-contamination will occur, thus interfering with the fermentation process.

[0003] In summary, this application proposes a fermentation device for birch sap with antibacterial function, which improves the aforementioned technical problems. Summary of the Invention

[0008] Furthermore, the aforementioned birch sap fermentation device with antibacterial function also includes a collection component, which includes a cover and a second pipe; a number of permeable grooves are opened on the cylinder; the cover is fixed to the outside of the cylinder; a cavity is formed between the cover and the cylinder, and the cavity communicates with the second permeable groove; a second pipe is fixed to the cover, and the second pipe communicates with the cavity.

[0009] Furthermore, in the aforementioned birch sap fermentation device with antibacterial function, the lower part of the casing is inclined.

[0010] Furthermore, the above-mentioned birch sap fermentation device with antibacterial function also includes a flushing component, which includes a connecting plate and a pipe three; the connecting plate is fixedly connected to the inner side of the cylinder; the pipe three is fixedly connected to the connecting plate and passes through the cylinder cover one; a cavity two is opened in the connecting plate and communicates with the pipe three; a number of water passage holes are opened on the connecting plate and communicate with the cavity two.

[0011] Furthermore, the aforementioned birch sap fermentation device with antibacterial function also includes a pipe four; the pipe four is fixedly connected to the connecting plate and passes through the cylinder cover one; a cavity three is opened in the connecting plate and is connected to the pipe four; a number of vent holes are opened in the connecting plate and are connected to the cavity three.

At the same time, the stirring blade can also be used to block the permeable trough, so as to form a closed space between the cylinder, the circular ring, and the connecting plate. That is, impurities are wrapped in the closed space before rinsing, which can prevent water and impurities from flowing into the birch sap mixture and interfering with the fermentation. In addition, the stirring blade used to stir and block the permeable trough can also be used to scrape off impurities adhering to the bottom of the inner side of the cylinder, which helps to improve the cleaning efficiency.

[0018] Second, the air supplied through pipe four blows away the birch sap mixture remaining on the upper end of ring one, effectively preventing the birch sap mixture from remaining on the connecting plate and thus avoiding interference with the fermentation process. At the same time, air is supplied through pipe five to the sealed space between the cylinder, ring one, and connecting plate, blowing away water droplets and preventing them from falling into the birch sap mixture and interfering with the fermentation. Furthermore, the air supplied through pipe six blows away the clean water that has accumulated in the permeable tank one, preventing interference with the fermentation process due to incomplete removal of clean water.

[0029] Example 1: A fermentation device for birch sap with antibacterial function, such as... Figures 1-8 As shown, the assembly includes a cylinder 1 and supports 2; three supports 2 are welded to the lower side of the cylinder 1, and the supports 2 are made of alloy material; it also includes a cylinder cover 3, a cylinder cover 4, a pipe 5, a cover 6, a stirring blade 7, a ring 8, a filter screen 9, and auxiliary components; the cylinder cover 3 is bolted to the upper side of the cylinder 1; the cylinder cover 4 is screwed onto the cylinder cover 3; the pipe 5 is connected and welded to the lower side of the cylinder 1; the cover 6 is screwed onto the pipe 5; the auxiliary components are connected to the cylinder cover 3; four stirring blades 7 are connected to the auxiliary components, and the stirring blades 7 are located inside the cylinder 1; the ring 8 is slidably connected to the inner side of the cylinder 1, and the ring 8 is rotatably connected to the stirring blades 7; four through grooves 91 are opened on the ring 8; four filter screens 9 are fixed to the ring 8, and the filter screens 9 are located in the corresponding through grooves 91, through which impurities are intercepted.

[0030] The auxiliary components include a connecting rod 10, a second stirring blade 11, a spring 12, a multi-stage hydraulic rod 201, a connecting block 202, a motor 203, a round rod 204, and a second ring 205; two multi-stage hydraulic rods 201 are bolted to the cylinder cover 3; all the telescopic ends of the multi-stage hydraulic rods 201 are fixedly connected to the connecting block 202, which is made of alloy material; the motor 203 is bolted to the connecting block 202; the output end of the motor 203 is fixedly connected to the round rod 204, which is rotatably connected to the connecting block 202; each stirring blade... All components 1 and 7 are fixedly connected to the round rod 204; a second ring 205 is rotatably connected to the cylinder cover 3, and the second ring 205 is slidably connected to the round rod 204. The motor 203 drives the round rod 204 to rotate, and the round rod 204 drives the second ring 205 to rotate on the cylinder cover 3; a connecting rod 10 is slidably connected to the round rod 204; four stirring blades 21 are welded to the connecting rod 10; a spring 12 is fixedly connected to the connecting rod 10, and the spring 12 is fixedly connected to the round rod 204; four clearance grooves 98 are opened on the round rod 204, and the clearance grooves 98 are aligned with the corresponding stirring blades 21.

[0031] It also includes a collection component, which includes a cover 206 and a pipe 207; four through slots 92 are provided on the cylinder 1; the cover 206 is fixed to the outside of the cylinder 1; a cavity 93 is formed between the cover 206 and the cylinder 1, and the cavity 93 communicates with the through slots 92; the pipe 207 is fixed to the cover 206, and the pipe 207 communicates with the cavity 93.

[0032] The lower part of the cover 206 is inclined, which can guide the impurities inside to the pipe 207, thereby improving the impurity collection efficiency.

[0033] It also includes a flushing assembly, which includes a connecting plate 208 and a pipe 209. The connecting plate 208 is fixedly connected to the inside of the cylinder 1. The pipe 209 is fixedly connected to the connecting plate 208 and passes through the cylinder cover 3. A cavity 94 is opened inside the connecting plate 208 and is connected to the pipe 209. Several water holes 96 are opened on the connecting plate 208 and are connected to the cavity 94. The pipe 209 delivers clean water to the cavity 94 and the clean water is sprayed out from the water holes 96.

[0034] First, manually connect the external sewage pipe to pipe 207 and the external water inlet pipe to pipe 209. Then, open the cylinder cover 24 and inject the birch sap mixture into the cylinder 1, ensuring the liquid level of the birch sap mixture is below the permeable tank 292. Then, close the cylinder cover 24 and allow it to ferment. During the fermentation process, stir regularly to ensure the birch sap is fully fermented. Specifically, the multi-stage hydraulic rod 201 drives the connecting block 202 upward, and the connecting block 202... 02 drives motor 203 and round rod 204 to move upward, and round rod 204 slides upward within ring 205. Round rod 204 drives stirring blade 7 and ring 8 to move upward, so that the upper part of ring 8 extends to the surface of birch sap. Motor 203 is started, and motor 203 drives round rod 204 to rotate. Round rod 204 drives ring 205 to rotate on cylinder cover 3. Round rod 204 drives stirring blade 7 to rotate on ring 8. Stirring blade 7 stirs the birch sap. The upper part of the birch sap mixture is stirred, while the round rod 204 drives the connecting rod 10 and the stirring blade 11 to rotate. The stirring blade 11 stirs the lower part of the birch sap mixture. During the stirring process, the funnel-shaped ring 8 intercepts the floating birch sap mixture to prevent it from adhering to the liquid surface above the inner wall of the cylinder 1. After stirring is completed, the motor 203 is turned off, and the stirring blades 7 and 11 stop rotating. Then, the multi-stage hydraulic rod 201 drives the connecting block 202 and its parts to move downward back to their original position. After fermentation is completed, the external collection tank is manually placed below the pipe 5, and then the cover 6 is opened to allow the fermentation products in the cylinder 1 to be discharged from the pipe 5 into the external collection tank. In use, the ring 8 intercepts the floating birch sap mixture to prevent it from adhering to the liquid surface above the inner wall of the cylinder 1, thus avoiding the problem of mycelium growth due to residue on the inner wall of the cylinder 1 interfering with the birch sap fermentation.

[0035] During fermentation, some microorganisms (such as yeast and filamentous fungi) have the characteristic of adhering to the wall and can form a biofilm on the inner wall of cylinder 1. Such biofilms can cause metabolic interference and pollution spread in birch sap fermentation. Therefore, before fermentation, the multi-stage hydraulic rod 201 drives the connecting block 202 and its parts downward, so that the connecting rod 10 and the stirring blade 11 contact the bottom of the inner side of cylinder 1. The multi-stage hydraulic rod 201 drives the connecting block 202 to continue downward, while the connecting rod 10 and the stirring blade 11 are blocked by the cylinder 1 and remain stationary, so that the circular rod 204 moves downward relative to the connecting rod 10 and compresses the spring 12 until the lower side of the stirring blade 7 and the lower side of the ring 8 both contact the bottom of the inner side of cylinder 1. Then the fermentation operation is carried out. During this process, the clearance groove 98 provides clearance space for the stirring blade 11. During stirring, the multi-stage hydraulic rod 201 drives the connecting block 202 and its parts to move downward. The upward movement causes the ring 8 to move upward along the inner wall of the cylinder 1, scraping away the biofilm remaining on the inner wall of the cylinder 1. After stirring, the stirring blade 7 is rotated by the motor 203, so that the stirring blade 7 is misaligned with the permeable groove 91. Then, the multi-stage hydraulic rod 201 drives the connecting block 202 and its parts to move upward, causing the ring 8 to continue to move upward until the lower part of the ring 8 is aligned with the lower part of the permeable groove 92. During this process, the birch sap mixture flows back into the cylinder 1 through the permeable groove 91. The scraped impurities are intercepted by the filter screen 9, and the impurities will flow obliquely outward along the surface of the ring 8 into the permeable groove 92, and then flow into the cavity 93 for collection. In use, the ring 8, which is used to intercept the birch sap mixture, can also be used to scrape away the biofilm on the inner wall of the cylinder 1, which helps to reduce interference with the fermentation of birch sap and ensure the fermentation effect.

[0036] The scraped impurities have a certain degree of adhesion, preventing them from being completely discharged into cavity 93. When ring 8 returns to its original position, some impurities fall back into cylinder 1, interfering with the fermentation of the birch sap mixture. Therefore, when the lower part of ring 8 aligns with the lower part of permeable groove 92, the upper part of ring 8 is just touching connecting plate 208. At this time, a sealed space is formed between cylinder 1, ring 8, and connecting plate 208. Motor 203 controls the rotation of stirring blade 7, causing stirring blade 7 to block permeable groove 91. Then, clean water is supplied to pipe 209 through external water inlet pipe. The clean water flows into cavity 94 through pipe 209. Water is sprayed downwards from the water inlet 96 into the sealed space, then flows through the permeable channel 2 92 into the cavity 1 93, and then through the pipe 207 into the external drain pipe. During this process, clean water can flush impurities into the external drain pipe, completing the cleaning operation. When in use, clean water is used to rinse away the impurities scraped off by the ring 8, preventing impurities from falling back into the cylinder 1 and interfering with the birch sap fermentation. At the same time, the stirring blade 7 can also be used to block the permeable channel 91, so that a sealed space is formed between the cylinder 1, the ring 8 and the connecting plate 208. That is, the impurities are covered in the sealed space before the rinsing operation, which can prevent clean water and impurities from flowing into the birch sap mixture and interfering with the fermentation.

[0037] After fermentation, when cleaning cylinder 1, clean water is injected into cylinder 1. The stirring blade 7 is controlled by the multi-stage hydraulic rod 201 to contact the bottom of the inner side of cylinder 1. Then, the stirring blade 7 is controlled by the motor 203 to rotate, thereby scraping off the impurities adhering to the bottom of the inner side of cylinder 1. Then, the ring 8 is controlled by the multi-stage hydraulic rod 201 to move upward, and the ring 8 scrapes off the impurities adhering to the inner wall of cylinder 1. This helps to improve cleaning efficiency. In use, the stirring blade 7, which is used to stir and block the through groove 91, can also be used to scrape off the impurities adhering to the bottom of the inner side of cylinder 1, which helps to improve cleaning efficiency.

[0038] Example 2, based on Example 1, such as Figures 4-8 As shown, it also includes a pipe 2010; the pipe 2010 is fixedly connected to the connecting plate 208, and the pipe 2010 passes through the cylinder cover 3; a cavity 95 is opened in the connecting plate 208, and the cavity 95 is connected to the pipe 2010; a number of vent holes 97 are opened in the connecting plate 208, and the vent holes 97 are connected to the cavity 95. The pipe 2010 delivers gas to the cavity 95, and the gas is ejected from the vent holes 97.

[0039] It also includes pipe 52011; four pipes 52011 are fixed on the connecting plate 208, and pipes 52011 pass through the cylinder cover 13.

[0040] It also includes pipe six 2012; four pipes six 2012 are fixed on the cylinder 1, and pipes six 2012 are aligned with the corresponding filter screens 9.

[0041] The opening of pipe 62012 is designed as a constricted opening, which can pressurize the ejected airflow.

[0042] Both the stirring blade 7 and the ring 8 are made of wear-resistant material to reduce wear and increase service life.

[0043] First, the external air intake pipe is manually connected to pipe 4 2010. When using clean water to rinse away the impurities scraped off by ring 8, ring 8 needs to contact the connecting plate 208. After ring 8 emerges from the birch sap mixture, some birch sap mixture will remain on the upper part of ring 8. After ring 8 contacts the connecting plate 208, the birch sap mixture on ring 8 will adhere to the connecting plate 208. Subsequently, the birch sap mixture remaining on the connecting plate 208 will grow mycelium, interfering with birch sap fermentation. Therefore, when ring 8 moves upwards and approaches the connecting plate 208, through the external... Air is supplied through the air inlet pipe to pipe 4 2010. The air flows into cavity 3 95 through pipe 4 2010 and then blows downwards from the vent 97 to the upper end of ring 1 8, blowing away the birch sap mixture remaining on the upper end of ring 1 8. Pipe 4 2010 stops supplying air, and ring 1 8 continues to move upwards and fits against connecting plate 208, avoiding the problem of residue. In use, the air supplied through pipe 4 2010 blows away the birch sap mixture remaining on the upper end of ring 1 8, which can effectively prevent the birch sap mixture from remaining on connecting plate 208, thereby avoiding interference with the fermentation operation.

[0044] First, the external air intake pipe is manually connected to pipe 2011. After rinsing away the impurities scraped off by ring 8 with clean water, water droplets remain in the sealed space between cylinder 1, ring 8, and connecting plate 208. If ring 8 is controlled to move directly back to the bottom of cylinder 1, the water droplets will flow into the birch sap mixture, interfering with the fermentation process. Therefore, after rinsing away the impurities scraped off by ring 8 with clean water, air is supplied to pipe 2011 through the external air intake pipe. The air then flows through pipe 2011... 011 flows into the sealed space, then through the second permeable channel 92 into the first cavity 93, and then through the second pipe 207 into the external drain pipe, thereby blowing away the water droplets remaining in the sealed space and preventing them from falling into the birch sap mixture and interfering with fermentation. In use, air is supplied to the sealed space between the cylinder 1, the first ring 8 and the connecting plate 208 through the fifth pipe 2011, and the air blows away the water droplets in it, preventing them from falling into the birch sap mixture and interfering with fermentation.

[0045] First, the external air intake pipe is manually connected to pipe six 2012. When air is used to blow away the water droplets remaining in the sealed space between cylinder 1, ring one 8 and connecting plate 208, some water will accumulate in the permeable groove one 91. The air flowing in the sealed space is difficult to blow it away. Therefore, air is supplied to pipe six 2012 through the external air intake pipe. Pipe six 2012 blows the air into the permeable groove one 91, thereby blowing out the water that has accumulated in the permeable groove one 91, effectively avoiding residue. During use, the air supplied through pipe six 2012 blows away the water that has accumulated in the permeable groove one 91, avoiding interference with the fermentation operation due to incomplete removal of water.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
