Description

Technical Field

[0001] The present invention relates to the technical field of craft beer brewing, and particularly to a high-efficiency fermentation device and operation method for craft beer. Background Art

[0002] Beer is an alcoholic beverage brewed mainly from wheat malt and barley malt, with the addition of hops. It undergoes liquid gelatinization and saccharification, and then liquid fermentation. The main equipment for beer fermentation is a fermentation tank. During the fermentation process, the fermentation temperature is controlled by circulating coolant through a cooling jacket. Different beer styles require different fermentation temperatures, generally between 10°C and 25°C. Precise temperature control helps the growth and metabolism of yeast, ensures the smooth progress of the fermentation process, and also affects the flavor and taste of beer.

[0003] To ensure the fermentation quality and efficiency of craft beer, inoculated yeast is generally added into the fermentation tank. In the initial stage of fermentation, the ventilation system introduces an appropriate amount of sterile air into the wort to meet the oxygen demand for the growth and reproduction of yeast. As fermentation progresses, the ventilation volume is gradually reduced until ventilation stops, allowing the yeast to ferment under anaerobic conditions to produce alcohol. A stirrer is used to evenly mix the wort, enabling the yeast to fully contact the wort, preventing yeast precipitation, and improving fermentation efficiency.

[0004] However, in actual use, the method of directly adding inoculated yeast into the fermentation tank requires opening the fermentation tank, which will cause changes in the temperature and pressure inside the tank, allowing carbon dioxide to escape and oxygen to enter, thereby affecting the activity of the inoculated yeast and fermentation efficiency, and reducing the efficiency of beer fermentation.

[0015] An operation method of a high-efficiency fermentation device for craft beer, including a high-efficiency fermentation device for craft beer, the method includes the following steps:

[0016] S1: When it is necessary to add inoculated yeast and additives into the fermenter, the stirring shaft inside the fermenter rotates and contacts the arc-shaped block, which will push the arc-shaped block to move to the right. Then, the arc-shaped block drives the blocking block one to move to the right, squeezing the elastic part one to deform elastically. Consequently, the blocking block one no longer blocks the outlets of the two storage tanks, enabling the inoculated yeast and additives inside the two storage tanks to enter the placement groove respectively and stay on the left side of the blocking block one. When the stirring shaft no longer contacts the arc-shaped block, the elastic part one performs a reset movement, thereby pushing the blocking block one to move to the left, causing the blocking block one to squeeze the inoculated yeast and additives to enter the fermenter through the through groove. Thus, it is possible to add inoculated yeast and additives without opening the fermenter.

[0017] S2: When the inoculated yeast inside the fermenter ferments, the generated carbon dioxide containing water vapor enters the exhaust pipe and then flows to the other end of the exhaust pipe. A large amount of carbon dioxide containing water vapor is filtered by the screen one, allowing the relatively dry carbon dioxide to enter the installation cover and then enter the collection tank through the connecting pipe. At this time, the limiting block is snapped into the limiting groove, causing the blocking block one to pull the pull rope one to move through the pull rope two. Then, the pull rope two drives the push plate to move. When the push plate moves to the right, it squeezes the elastic part three to deform, and the carbon dioxide on the right side inside the collection tank squeezes the movable piece, causing the upper and lower movable pieces to rotate to the left and squeezing the elastic part four to deform. At this time, the carbon dioxide on the right side inside the collection tank enters the left side of the push plate. When the blocking block one moves to the left, the blocking block one no longer pulls the pull rope two. At this time, the elastic part three performs a reset movement, thereby pushing the push plate to move to the left, and the elastic part four performs a reset movement, causing the elastic part four to push the movable piece to close. Thus, the movement of the push plate to the left is sealed. Under the movement of the push plate to the left, the carbon dioxide on the left side inside the collection tank enters the fermenter through the exhaust hole to add carbon dioxide to the fermenter and reduce the oxygen content inside the fermenter.

[0018] S3: When the first blocking block moves to the right, the first blocking block can push the connecting rod to move to the right, and then the connecting rod can push the connecting piece to move to the right, and then the connecting piece can slide on the inner wall of the first screen. Under the continuous movement of the connecting piece, the knocking block gradually contacts the arc-shaped ring, causing the knocking block to move inward when contacting, and then the knocking block can squeeze the second elastic member to deform, and then the second elastic member can perform a reset movement. As the connecting piece continues to move, when the knocking block is no longer in contact with the arc-shaped ring, the second elastic member performs a reset movement, and then can push the knocking block to knock the inner wall of the first screen, causing the first screen to vibrate, and then a large amount of condensed water adhering to the inner wall of the first screen can drip, so as to improve the collection efficiency of carbon dioxide;

[0019] S4: When the inoculated yeast or additive inside the storage tank needs to be added, by pulling the clamping member, the clamping member can be deformed, and then the clamping member can be disengaged from the inside of the clamping groove. Then, by pulling the baffle, the baffle can be rotated counterclockwise. At this time, pull the extension tube to the right, so that the extension tube can pull the second blocking block to move to the right through the pull rod, and then the pull rod can block the hole on the lower side of the inner wall of the storage tank, so that the inoculated yeast and additive inside the storage tank will not enter the inside of the placement groove. At this time, the inoculated yeast and additive can be added to the storage tank by using the path formed between the extension tube and the baffle.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the present invention, by designing a chemical addition passage on the inner wall of the fermentation tank, and then using the rotation of the stirrer to control the movement of the arc-shaped block, so as to control the quantitative addition of inoculated yeast and additive to the inside of the fermentation tank. And a screen and a mounting cover are installed inside the exhaust pipe for collecting the discharged carbon dioxide, and a push plate is used to pressurize it into the fermentation tank, so as to prevent excessive oxygen content, so that the inoculated yeast will not be over-oxidized, and then help to maintain the chemical stability and microbial stability of beer brewing, so as to ensure the beer fermentation quality and make the use economy relatively high.

Detailed implementation manner

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1: Please refer to Figures 1 to 17, the present invention provides a technical solution: a high-efficiency fermentation device for craft beer, including a fermentation tank 1. A discharge pipe 7 is fixedly connected to the right side of the fermentation tank 1. The fermentation tank 1 is the main part of the fermentation device, and heaters, sensors, controllers, etc. are installed inside it. The fermentation temperature is controlled by circulating coolant through the cooling jacket. Precise temperature control helps the growth and metabolism of the inoculated yeast, ensures the smooth progress of the fermentation process, and also affects the flavor and taste of the beer. A placement groove 2 is opened inside the fermentation tank 1. The placement groove 2 is used for the circulation of the inoculated yeast and additives. The additives can be divided into nitrogen sources, carbon sources, and vitamins, which can provide energy for the inoculated yeast, promote the activity, growth, and metabolic activities of the inoculated yeast, and improve the stability and efficiency of fermentation. A blocking block 3 is slidably connected inside the placement groove 2. The placement groove 2 plays a limiting role on the blocking block 3, so that the blocking block 3 will not shift when sliding. An arc-shaped block 4 is fixedly connected to the left side of the blocking block 3. A plurality of through grooves 5 are opened on the outer side of the arc-shaped block 4. The through grooves 5 provide a space for the inoculated yeast and additives to enter the inside of the fermentation tank 1. Two storage grooves 6 are opened on the upper side of the inner wall of the placement groove 2. One of the storage grooves 6 is used for storing the inoculated yeast, and the other storage groove 6 is used for storing additives. A first screen 8 is detachably connected to the left side of the outer part of the discharge pipe 7. The first screen 8 is made of polydimethylsiloxane and its modified membrane, which can block oxygen and water vapor and allow carbon dioxide to pass through. A connecting piece 21 is slidably connected inside the first screen 8. The connecting piece 21 is used to scrape the inner wall of the first screen 8 to prevent the condensate from blocking the first screen 8 and ensure that carbon dioxide can pass through the first screen 8 smoothly. An installation cover 9 is sleeved on the outer part of the first screen 8. The top end of the installation cover 9 is fixedly connected to a connecting pipe 10. The other end of the connecting pipe 10 communicates with a collection tank 11. The installation cover 9 is used to guide the carbon dioxide passing through the first screen 8 into the inside of the collection tank 11 through the connecting pipe 10, and its condensate can pass through the connecting part of the first screen 8 to the lower side of the inside of the installation cover 9. Then, installing a valve at the bottom of the installation cover 9 can complete the collection of the condensate to improve the economic efficiency of the device. A push plate 12 is slidably connected inside the collection tank 11. The collection tank 11 provides an environment for the pressurization of carbon dioxide. A plurality of exhaust holes 13 are fixedly connected to the left side of the inner wall of the collection tank 11. The push plate 12 is used to push carbon dioxide into the inside of the fermentation tank 1 through the exhaust holes 13, so as to ensure the balance of oxygen and carbon dioxide inside the fermentation tank 1. A waterproof filter membrane is installed at the part where the exhaust holes 13 are in contact with the fermentation tank 1 to prevent the liquid inside the fermentation tank 1 from entering the inside of the collection tank 11.

[0042] Embodiment 2: On the basis of Embodiment 1, in order to achieve a convenient movable connecting piece 21, a connecting rod 18 is fixedly connected to the right end of the first plugging block 3. The first plugging block 3 is used to push the connecting rod 18 to move. An elastic member 19 is sleeved outside the connecting rod 18. The connecting rod 18 plays a limiting role on the elastic member 19, so that the elastic member 19 will not shift when deforming. One end of the connecting rod 18 away from the first plugging block 3 is fixedly connected to the connecting piece 21. A fixing piece 20 is slidably connected to the outside of the connecting rod 18. The fixing piece 20 plays a limiting role on the connecting rod 18, so that the connecting rod 18 will not shift when sliding. And the fixing piece 20 is used to seal the placement groove 2, so that the gas inside the exhaust pipe 7 inside the placement groove 2 will not enter the inside of the placement groove 2. One end of the elastic member 19 is fixedly connected to the fixing piece 20, and the other end of the elastic member 19 is fixedly connected to the first plugging block 3. The fixing piece 20 is fixedly connected to the inner wall of the exhaust pipe 7.

[0043] Embodiment 3: On the basis of Embodiment 2, in order to ensure that the condensate water will not block the aperture of the first screen 8, a plurality of arc-shaped rings 37 are fixedly connected inside the first screen 8. An installation groove 22 is formed inside the connecting piece 21. The connecting piece 21 is slidably connected to the inner side of the arc-shaped ring 37, so that the connecting piece 21 can be not blocked by the arc-shaped ring 37 and can scrape the inner wall of the first screen 8, so as to scrape off the condensate water. An elastic member 23 is fixedly connected to the inner wall of the installation groove 22. One side of the elastic member 23 away from the installation groove 22 is fixedly connected to a knocking block 24. The knocking block 24 slides with the arc-shaped ring 37. Under the deformation of the elastic member 23, the knocking block 24 can be pushed by the arc-shaped ring 37 and slide into the inside of the installation groove 22. And under the reset action of the elastic member 23, the knocking block 24 can knock the first screen 8, so that the condensate water not scraped off by the connecting piece 21 falls off through vibration. The knocking block 24 is slidably connected to the inner wall of the installation groove 22. The installation groove 22 plays a limiting role on the knocking block 24, so that the knocking block 24 will not shift when moving.

[0044] Embodiment 4: On the basis of Embodiment 3, in order to conveniently transport the carbon dioxide inside the collection tank 11 to the inside of the fermentation tank 1, a plurality of movable pieces 35 are hinged inside the push plate 12. Two elastic members four 36 are fixedly connected to the left side of the movable piece 35. The other end of the elastic member four 36 is fixedly connected to the inner wall of the push plate 12. The elastic members four 36 are evenly distributed on the push plate 12 and the movable piece 35, enabling the movable piece 35 to rotate conveniently. Then, when the two movable pieces 35 are not in contact, the carbon dioxide on the right side inside the collection tank 11 can enter the left side inside the collection tank 11 through the push plate 12. Then, after the movable pieces 35 on the upper and lower sides are attached to each other, a sealed space is formed between the push plate 12 and the collection tank 11. Then, when the push plate 12 moves to the left, the push plate 12 can push the carbon dioxide into the inside of the fermentation tank 1. A plurality of elastic members three 34 are fixedly connected to the side of the push plate 12 close to the first pull rope 14. The other end of the elastic member three 34 is fixedly connected to the inner wall of the collection tank 11. The elastic members three 34 are used to assist the movement of the push plate 12. Two first pull ropes 14 are fixedly connected to the right side of the push plate 12. The first pull ropes 14 are slidably connected inside the collection tank 11. The collection tank 11 plays a limiting role on the first pull ropes 14, so that the first pull ropes 14 will not deviate when sliding. A limiting groove 15 is provided at the end of the first pull rope 14 away from the push plate 12. A limiting block 16 is slidably connected inside the limiting groove 15. The end of the limiting block 16 away from the limiting groove 15 is fixedly connected to a second pull rope 17. The other end of the second pull rope 17 is fixedly connected to the first blocking block 3. The second pull rope 17 is slidably connected inside the placement groove 2. After the limiting block 16 is slid into the limiting groove 15, the second pull rope 17 and the first pull rope 14 can be connected. Both the second pull rope 17 and the first pull rope 14 are steel wires. Then, when the first blocking block 3 moves, it can drive the push plate 12 to move synchronously. Since the limiting groove 15 and the limiting block 16 can be separated from each other, carbon dioxide can be selectively added according to the carbon dioxide and oxygen content inside the fermentation tank 1.

[0045] Example 5: On the basis of Example 4, in order to selectively add inoculated yeast or additives into the interior of the fermentation tank 1, two feeding pipes 25 are fixedly connected to the right side of the inner wall of the storage tank 6. A baffle 29 is hinged to the upper side inside the feeding pipe 25. A clamping groove 30 is formed inside the right side of the baffle 29. A clamping member 28 is clamped inside the clamping groove 30. The right side of the clamping member 28 is fixedly connected to an extension pipe 27, so that the baffle 29 and the extension pipe 27 can close the feeding channel of the storage tank 6 after being connected. Two pull rods 33 are fixedly connected to the left side of the extension pipe 27. Two limiting strips 31 are fixedly connected to the inside of the storage tank 6. A second blocking block 32 is slidably connected to the lower side of the limiting strip 31. A sliding groove 26 is formed inside the lower side of the feeding pipe 25. The extension pipe 27 is slidably connected inside the sliding groove 26. The sliding groove 26 plays a role in limiting the extension pipe 27, so that the extension pipe 27 will not break away from the inside of the feeding pipe 25. The right side of the baffle 29 is in contact with the left side of the extension pipe 27. The bottom end of the second blocking block 32 is slidably connected to the lower side of the inner wall of the storage tank 6. The pull rod 33 is slidably connected to the inside of the fermentation tank 1. The fermentation tank 1 plays a role in limiting the pull rod 33, so that the pull rod 33 will not deviate during movement. The pull rod 33 is used to connect the second blocking block 32 and the extension pipe 27, so that the extension pipe 27 can pull the second blocking block 32 to move. Since the two feeding pipes 25 are designed separately, the corresponding pipes can be selected to be opened according to the fermentation time to add inoculated yeast and additives, thereby improving the fermentation efficiency.

[0046] Example 6: On the basis of Example 5, an operation method for an efficient fermentation device for craft beer is proposed, including an efficient fermentation device for craft beer. The method includes the following steps:

[0047] S1: When it is necessary to add inoculated yeast and additives into the fermentation tank 1, the stirring shaft inside the fermentation tank 1 rotates and contacts the arc-shaped block 4, which will push the arc-shaped block 4 to move to the right. Then, the arc-shaped block 4 drives the first blocking block 3 to move to the right, and squeezes the first elastic member 19 to make an elastic deformation. Then, the first blocking block 3 no longer blocks the outlets of the two storage tanks 6. Then, the inoculated yeast and additives inside the two storage tanks 6 enter the inside of the placement groove 2 respectively and stay on the left side of the first blocking block 3. When the stirring shaft no longer contacts the arc-shaped block 4 at this time, the first elastic member 19 makes a reset movement, and then pushes the first blocking block 3 to move to the left, so that the first blocking block 3 squeezes the inoculated yeast and additives to enter the fermentation tank 1 through the through groove 5. Therefore, inoculated yeast and additives can be added without opening the fermentation tank 1.

[0048] S2: When the inoculated yeast inside the fermenter 1 ferments, the carbon dioxide containing water vapor is able to enter the inside of the exhaust pipe 7, and then flows towards the other end of the exhaust pipe 7. A large amount of carbon dioxide containing water vapor is filtered by the first screen 8, so that relatively dry carbon dioxide can enter the inside of the mounting cover 9 and enter the inside of the collection tank 11 through the connecting pipe 10. At this time, the limiting block 16 is clamped inside the limiting groove 15, and then the first blocking block 3 is able to pull the first pull rope 14 to move through the second pull rope 17, so that the second pull rope 17 drives the push plate 12 to move. Then, when the push plate 12 moves to the right, it is able to squeeze the third elastic member 34 to deform, and the carbon dioxide on the right side inside the collection tank 11 is able to squeeze the movable piece 35, so that the upper and lower movable pieces 35 rotate to the left, and squeeze the fourth elastic member 36 to deform. At this time, the carbon dioxide on the right side inside the collection tank 11 enters the left side of the push plate 12. Then, when the first blocking block 3 moves to the left, the first blocking block 3 no longer pulls the second pull rope 17. At this time, the third elastic member 34 makes a reset movement, and then is able to push the push plate 12 to move to the left, and the fourth elastic member 36 makes a reset movement so that the fourth elastic member 36 is able to push the movable piece 35 to close. Then, the movement of the push plate 12 to the left is airtight. Under the movement of the push plate 12 to the left, the carbon dioxide on the left side inside the collection tank 11 is able to enter the inside of the fermenter 1 through the exhaust hole 13, so as to add carbon dioxide to the inside of the fermenter 1 and reduce the oxygen content inside the fermenter 1;

[0049] S3: When the first blocking block 3 moves to the right, the first blocking block 3 is able to push the connecting rod 18 to move to the right, and then the connecting rod 18 is able to push the connecting piece 21 to move to the right, and then the connecting piece 21 is able to slide on the inner wall of the first screen 8. Under the continuous movement of the connecting piece 21, the knocking block 24 gradually contacts the arc-shaped ring 37, so that the knocking block 24 moves inward when contacting, and then the knocking block 24 is able to squeeze the second elastic member 23 to deform, and then the second elastic member 23 makes a reset movement. With the continuous movement of the connecting piece 21, when the knocking block 24 no longer contacts the arc-shaped ring 37, the second elastic member 23 makes a reset movement, and then is able to push the knocking block 24 to knock the inner wall of the first screen 8, so that the first screen 8 generates vibration, and then a large amount of condensed water attached to the inner wall of the first screen 8 drips, so as to improve the collection efficiency of carbon dioxide;

[0050] S4: When the inoculated yeast or additives inside the storage tank 6 need to be added, by pulling the card 28, the card 28 is deformed, so that the card 28 can be disengaged from the inside of the card slot 30. Then, by pulling the baffle 29, the baffle 29 can be rotated counterclockwise. At this time, the extension tube 27 is pulled to the right, so that the extension tube 27 can pull the second blocking block 32 to move to the right through the pull rod 33. As a result, the pull rod 33 can block the hole on the lower side of the inner wall of the storage tank 6, so that the inoculated yeast and additives inside the storage tank 6 will not enter the inside of the placement tank 2. At this time, the inoculated yeast and additives can be added into the storage tank 6 through the path formed between the extension tube 27 and the baffle 29.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.

10. An operating method of an efficient fermentation device for craft beer, characterized in that, Including the high-efficiency fermentation equipment for craft beer according to any one of the above claims 1-9, the method includes the following steps: S1: When it is necessary to add inoculated yeast and additives into the fermentation tank (1), the stirring shaft inside the fermentation tank (1) rotates and contacts the arc-shaped block (4), which will push the arc-shaped block (4) to move to the right. Then, through the arc-shaped block (4), the first blocking block (3) is driven to move to the right, and the first elastic member (19) is squeezed to undergo elastic deformation. Consequently, the first blocking block (3) no longer blocks the outlets of the two storage tanks (6). Then, the inoculated yeast and additives inside the two storage tanks (6) respectively enter the inside of the placement groove (2) and stay on the left side of the first blocking block (3). At this time, when the stirring shaft no longer contacts the arc-shaped block (4), the first elastic member (19) undergoes a reset movement, and then it can push the first blocking block (3) to move to the left, enabling the first blocking block (3) to squeeze the inoculated yeast and additives to enter the inside of the fermentation tank (1) through the through groove (5). Thus, it is possible to add inoculated yeast and additives without opening the fermentation tank (1). S2: When the inoculated yeast inside the fermentation tank (1) ferments, the carbon dioxide containing water vapor generated enters the inside of the exhaust pipe (7), then flows towards the other end of the exhaust pipe (7). A large amount of carbon dioxide containing water vapor is filtered by the first screen (8), enabling relatively dry carbon dioxide to enter the inside of the installation cover (9) and enter the inside of the collection tank (11) through the connecting pipe (10). At this time, the limiting block (16) is snapped into the limiting groove (15), so that the first blocking block (3) can pull the first pull rope (14) to move through the second pull rope (17), enabling the second pull rope (17) to drive the push plate (12) to move. Then, when the push plate (12) moves to the right, it squeezes the third elastic member (34) to deform, and the carbon dioxide on the right side inside the collection tank (11) squeezes the movable piece (35), causing the upper and lower movable pieces (35) to rotate to the left and squeezing the fourth elastic member (36) to deform. At this time, the carbon dioxide on the right side inside the collection tank (11) enters the left side of the push plate (12). Then, when the first blocking block (3) moves to the left, the first blocking block (3) no longer pulls the second pull rope (17). At this time, the third elastic member (34) performs a reset movement, thereby driving the push plate (12) to move to the left, and the fourth elastic member (36) performs a reset movement so that the fourth elastic member (36) drives the movable piece (35) to close. Thus, the movement of the push plate (12) to the left is sealed. Under the movement of the push plate (12) to the left, the carbon dioxide on the left side inside the collection tank (11) enters the inside of the fermentation tank (1) through the exhaust hole (13) to add carbon dioxide to the inside of the fermentation tank (1) and reduce the oxygen content inside the fermentation tank (1); S3: When the first blocking block (3) moves to the right, the first blocking block (3) drives the connecting rod (18) to move to the right, so that the connecting rod (18) drives the connecting piece (21) to move to the right, and the connecting piece (21) slides on the inner wall of the first screen (8). Under the continuous movement of the connecting piece (21), the knocking block (24) gradually contacts the arc-shaped ring (37), causing the knocking block (24) to move inward when contacting, so that the knocking block (24) squeezes the second elastic member (23) to deform, and then the second elastic member (23) performs a reset movement. With the continuous movement of the connecting piece (21), when the knocking block (24) no longer contacts the arc-shaped ring (37), the second elastic member (23) performs a reset movement, thereby driving the knocking block (24) to knock the inner wall of the first screen (8), causing the first screen (8) to vibrate, and a large amount of condensed water attached to the inner wall of the first screen (8) drips, so as to improve the collection efficiency of carbon dioxide; S4: When the inoculated yeast or additive inside the storage tank (6) needs to be added, by pulling the buckle card (28), the card (28) is deformed, so that the card (28) can be detached from the inside of the card slot (30). Then, by pulling the baffle (29), the baffle (29) is reversely rotated counterclockwise. At this time, the extension tube (27) is pulled to the right, so that the extension tube (27) can pull the blocking block two (32) to move to the right through the pull rod (33). As a result, the pull rod (33) blocks the hole on the lower side of the inner wall of the storage tank (6), so that the inoculated yeast and additive inside the storage tank (6) will not enter the inside of the placement groove (2). At this time, the inoculated yeast and additive can be added into the storage tank (6) through the path formed between the extension tube (27) and the baffle (29).
