Description

Technical Field

[0001] The present invention relates to the technical field of fermentation equipment, and more particularly to a birch sap fermentation device with antibacterial function. Background Art

[0002] During the birch sap fermentation process, in order to ensure the fermentation effect, the birch sap needs to be stirred regularly. However, when the existing fermentation equipment stirs the birch sap, the birch sap will cause it to swirl and splash onto the inner wall of the fermentation barrel. As the fermentation progresses, the viscosity of the birch sap increases (such as bacterial proliferation and accumulation of metabolites), and the splashing materials are more likely to adhere and form solid residues, which are inconvenient to clean. Over time, mycelium will grow on this part of the residue. If it falls into the birch sap, cross contamination will occur, thereby interfering with the fermentation operation.

The motor 203 drives the circular rod 204 to rotate, and the circular rod 204 drives the circular ring 205 to rotate on the cylinder cover 1; the circular rod 204 is slidably connected to the connecting rod 10; four stirring blades 2 11 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 circular rod 204; four avoidance grooves 98 are opened on the circular rod 204, and the avoidance grooves 98 are aligned with the corresponding stirring blades 2 11.

[0021] It also includes a collecting component, which includes a cover 206 and a second pipe 207; four transparent grooves 2 92 are opened on the cylinder 1; the cover 206 is fixedly connected to the outside of the cylinder 1; a cavity 1 93 is formed between the cover 206 and the cylinder 1, and the cavity 1 93 is connected to the second transparent groove 92; the second pipe 207 is fixedly connected to the cover 206, and the second pipe 207 is connected to the cavity 1 93.

[0022] The lower portion of the cover 206 is tilted to guide the impurities inside it toward the second pipe 207, thereby improving the efficiency of collecting impurities.

[0023] It also includes a flushing component, which includes a connecting plate 208 and a pipe three 209; the connecting plate 208 is fixedly connected to the inner side of the cylinder 1; the pipe three 209 is fixedly connected to the connecting plate 208, and the pipe three 209 passes through the cylinder cover 1 3; a cavity 2 94 is opened in the connecting plate 208, and the cavity 2 94 is connected to the pipe three 209; a plurality of water holes 96 are opened on the connecting plate 208, and the water holes 96 are connected to the cavity 2 94, and the pipe three 209 transports clean water to the cavity 2 94, and the clean water is sprayed out from the water holes 96.

[0024] First, manually connect the external sewage pipe to the second pipe 207, connect the external water inlet pipe to the third pipe 209, then open the cylinder cover 24, inject the birch sap mixture into the cylinder 1, make the birch sap mixture liquid level lower than the transparent tank 2 92, then close the cylinder cover 24, and let it ferment. During the fermentation process, stir the birch sap regularly to make the birch sap fully fermented. The specific operation is as follows: the multi-stage hydraulic rod 201 drives the connecting block 202 to move upward, and the connecting block 2 02 drives the motor 203 and the round rod 204 to move upward, and the round rod 204 slides upward in the ring 2 205, and the round rod 204 drives the stirring blade 7 and the ring 18 to move upward, so that the upper part of the ring 18 extends to the surface of the birch sap, and the motor 203 is started. The motor 203 drives the round rod 204 to rotate, and the round rod 204 drives the ring 2 205 to rotate on the cylinder cover 3, and the round rod 204 drives the stirring blade 7 to rotate on the ring 18. The stirring blade 7 is used to stir the birch sap. The upper part of the sap mixture is stirred, and at the same time, the round rod 204 drives the connecting rod 10 and the stirring blade 2 11 to rotate, and the stirring blade 2 11 stirs the lower part of the birch sap mixture. During the stirring process, the birch sap mixture that is swirling is intercepted by the trumpet-shaped ring 18 to prevent it from adhering to the position above the liquid level on the inner wall of the cylinder 1. After the stirring is completed, the motor 203 is turned off, the stirring blade 1 7 and the stirring blade 2 11 stop rotating, and then the multi-stage hydraulic rod 201 drives the connecting block 202 and the parts thereon to move downward back to their original position. After the fermentation is completed, the external collection bucket is manually placed under the pipe 1 5, and then the lid 6 is opened to discharge the fermentation product in the cylinder 1 from the pipe 5 to the external collection bucket; when in use, the birch sap mixture that is swirling is intercepted by the ring 1 8 to prevent it from adhering to the position above the liquid level on the inner wall of the cylinder 1, thereby avoiding the problem of mycelium growing on the residue on the inner wall of the cylinder 1 interfering with the fermentation of birch sap.

[0025] During the fermentation process, some microorganisms (such as yeast and filamentous fungi) have the property of adhering to the wall and can form a biofilm on the inner wall of the cylinder 1. Such biofilms will cause metabolic interference and pollution diffusion problems to the fermentation of birch sap. Therefore, before the fermentation operation, the multi-stage hydraulic rod 201 drives the connecting block 202 and the parts thereon to move downward, so that the connecting rod 10 and the stirring blade 2 11 contact the inner bottom of the 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 2 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 1 8 both contact the inner bottom of the cylinder 1, and then the fermentation operation is carried out. During this process, the avoidance groove 98 is used to provide avoidance space for the stirring blade 2 11. During stirring, the multi-stage hydraulic rod 201 drives the connecting block 202 and the parts thereon to move downward. The upward movement causes the ring 18 to move upward along the inner wall of the cylinder 1 to scrape off the biofilm remaining on the inner wall of the cylinder 1. After the stirring is completed, the stirring blade 17 is controlled to rotate by the motor 203 so that the stirring blade 17 is staggered with the transparent groove 1 91. Then, the multi-stage hydraulic rod 201 drives the connecting block 202 and the parts thereon to move upward, causing the ring 18 to continue to move upward until the lower part of the ring 18 is aligned with the lower part of the transparent groove 2 92. During this process, the birch sap mixture passes through the transparent groove 1 91 and flows back into the cylinder 1. The scraped impurities are intercepted by the filter 9, and the impurities will flow obliquely outward along the surface of the ring 18 into the transparent groove 2 92, and then flow into the cavity 1 93 through the transparent groove 2 92 for collection. When in use, the ring 18 used to intercept the birch sap mixture can also be used to scrape off the biofilm on the inner wall of the cylinder 1, which is beneficial to reduce interference with the fermentation of birch sap to ensure the fermentation effect.

[0026] The scraped impurities have a certain degree of adhesion, which makes it impossible for the impurities to be completely discharged into the cavity 1 93. When the ring 1 8 moves back to its original position, some impurities will fall back into the cylinder 1, causing interference with the fermentation of the birch sap mixture. Therefore, when the lower part of the ring 1 8 is aligned with the lower part of the transparent groove 2 92, the upper part of the ring 1 8 just fits the connecting plate 208. At this time, a closed space is formed between the cylinder 1, the ring 1 8 and the connecting plate 208. The stirring blade 1 7 is controlled by the motor 203 to rotate, so that the stirring blade 1 7 blocks the transparent groove 1 91, and then, clean water is transported to the pipe 3 209 through the external water inlet pipe. The clean water flows into the cavity 2 94 through the pipe 3 209, and then It is sprayed downward from the water hole 96 into the enclosed space, then flows through the transparent groove 2 92 into the cavity 1 93, and then flows into the external sewage pipe through the pipe 2 207. During this process, the clean water can flush the impurities into the external sewage pipe to complete the cleaning operation. When in use, the impurities scraped off by the ring 1 8 are flushed away by clean water to prevent the impurities from falling back into the cylinder 1 and interfering with the fermentation of the birch sap. At the same time, the stirring blade 7 can also be used to block the transparent groove 1 91 to form a enclosed space between the cylinder 1, the ring 1 8 and the connecting plate 208, that is, the impurities are enclosed in the enclosed space and then the flushing operation is performed, which can prevent clean water and impurities from flowing into the birch sap mixture and interfering with the fermentation.

[0027] When cleaning the cylinder 1 after fermentation is completed, clean water is injected into the cylinder 1, and the stirring blade 7 is controlled by the multi-stage hydraulic rod 201 to contact the inner bottom of the cylinder 1, and then the stirring blade 7 is controlled to rotate by the motor 203, so that the impurities adhering to the inner bottom of the cylinder 1 are scraped off by the stirring blade 7, and then the ring 8 is controlled to move upward by the multi-stage hydraulic rod 201, and the impurities adhering to the inner wall of the cylinder 1 are scraped off by the ring 8, which is beneficial to improving the cleaning efficiency. When in use, the stirring blade 7 used for stirring and blocking the transparent groove 91 can also be used to scrape off impurities adhering to the inner bottom of the cylinder 1, which is beneficial to improving the cleaning efficiency.

[0028] Example 2, based on Example 1, Figure 4-Figure 8 As shown, it also includes a pipe four 2010; the pipe four 2010 is fixedly connected to the connecting plate 208, and the pipe four 2010 passes through the cylinder cover 3; a cavity three 95 is opened in the connecting plate 208, and the cavity three 95 is connected to the pipe four 2010; a plurality of vent holes 97 are opened in the connecting plate 208, and the vent holes 97 are connected to the cavity three 95, and the pipe four 2010 transports gas to the cavity three 95, and the gas is ejected from the vent holes 97.

[0029] It also includes a pipe five 2011; four pipes five 2011 are fixedly connected to the connecting plate 208, and the pipe five 2011 passes through the cylinder cover 1 3.

[0030] It also includes a pipe six 2012; four pipes six 2012 are fixedly connected to the cylinder 1, and the pipes six 2012 are aligned with the corresponding filter screens 9.

[0031] The opening of pipe six 2012 is configured to be in a constricted shape, which can pressurize the ejected air flow.

[0032] The stirring blade 7 and the ring 8 are both made of wear-resistant materials to reduce wear and increase service life.

[0033] First, manually connect the external air inlet pipe to the pipe 4 2010. When using clean water to flush out the impurities scraped off by the ring 18, the ring 18 needs to contact the connecting plate 208. After the ring 18 passes through the birch sap mixture, some birch sap mixture will remain on the upper end of the ring 18. After the ring 18 contacts the connecting plate 208, the birch sap mixture on the ring 18 will adhere to the connecting plate 208. The birch sap mixture remaining on the connecting plate 208 will grow hyphae and interfere with the fermentation of the birch sap. Therefore, when the ring 18 moves upward and approaches the connecting plate 208, it passes through the external An air inlet pipe is provided to convey air to the pipe four 2010. The air flows into the cavity three 95 through the pipe four 2010, and is then blown downward from the vent hole 97 to the upper end of the ring one 8, blowing away the birch sap mixture remaining on the upper end of the ring one 8. The pipe four 2010 stops conveying air, and the ring one 8 continues to move upward to fit the connecting plate 208, thereby avoiding the residue problem. During use, the air conveyed through the pipe four 2010 blows away the birch sap mixture remaining on the upper end of the ring one 8, which can effectively prevent the birch sap mixture from remaining on the connecting plate 208, thereby avoiding interference with the fermentation operation.

[0034] First, manually connect the external air inlet pipe to the pipe 5 2011. After using clean water to flush out the impurities scraped off by the ring 1-8, water droplets will remain in the closed space between the cylinder 1, the ring 1-8 and the connecting plate 208. If the ring 1-8 is controlled to move directly back to the bottom of the cylinder 1, the water droplets will flow into the birch sap mixture and interfere with the fermentation operation. Therefore, after using clean water to flush out the impurities scraped off by the ring 1-8, air is delivered to the pipe 5 2011 through the external air inlet pipe. The air passes through the pipe 5 2011. 011 flows into the enclosed space, then flows into the cavity 1 93 through the transparent groove 2 92, and then flows into the external sewage pipe through the pipe 2 207, so that the water droplets remaining in the enclosed space are blown away cleanly to prevent them from falling into the birch sap mixture and interfering with fermentation. When in use, air is transported to the enclosed space between the cylinder 1, the ring 1 8 and the connecting plate 208 through the pipe 5 2011, and the water droplets therein are blown away by the air to prevent them from falling into the birch sap mixture and interfering with fermentation.

[0035] First, the external air inlet pipe is manually connected to the pipe six 2012. When the water droplets remaining in the enclosed space between the cylinder 1, the ring 18 and the connecting plate 208 are blown away by air, some clean water will gather in the transparent groove 191, and it is difficult for the air flowing in the enclosed space to blow it away. Therefore, air is transported to the pipe six 2012 through the external air inlet pipe, and the pipe six 2012 blows the air into the transparent groove 191, thereby blowing out the clean water gathered in the transparent groove 191, effectively avoiding residue. When in use, the air transported through the pipe six 2012 will blow away the clean water gathered in the transparent groove 191, avoiding interference with the fermentation operation due to incomplete cleaning of the clean water.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
