Description

[0002] Beer is a low-alcohol fermented wine containing carbon dioxide, which is brewed from malt, hops, water and yeast. Beer can quench thirst, relieve fatigue, be beneficial to heart health, and help improve immunity. In beer production, a storage fermentation device is needed to provide a suitable environment for yeast to effectively ferment to produce alcohol and carbon dioxide. Currently, a fermentation tank is needed when fermenting beer. In particular, wort and yeast are added to the fermentation tank for fermentation. During the fermentation process, the temperature and pressure in the fermentation tank need to be adjusted adaptively.

DETAILED DESCRIPTION

[0049] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0050] As shown in Figures 1 to 11 the present application, a beer production fermentation device, comprising a fermentation tank 1, the top end of the fermentation tank 1 is connected and fixed with a first valve 11, the bottom end of the fermentation tank 1 is connected and fixed with a second valve 12, the output end of the second valve 12 is connected and fixed with a discharge pipe 13;

[0051] The inner wall of the fermentation tank 1 is fixedly connected with a support 2, the top end of the support 2 is rotationally connected with a receiving pipe 21, the top end of the receiving pipe 21 is in a blocked state; a plurality of exhaust pipes 3 are annularly and communicatively fixedly connected to the side surface of the receiving pipe 21, a plurality of exhaust holes 31 are formed in the top end of the exhaust pipe 3, a first blocking block 32 is inserted into the exhaust hole 31, a plurality of first grooves 321 are annularly formed in the bottom end of the first blocking block 32, a first spring 33 is fixedly connected between the first blocking block 32 and the inner wall of the exhaust pipe 3, and a plurality of first inclined baffles 4 are fixedly connected to the side surface of the receiving pipe 21 and located directly above the exhaust pipe 3;

[0052] The bottom end of the receiving pipe 21 is rotationally connected with a receiving cylinder 22, and the side surface of the receiving cylinder 22 is communicatively fixedly connected with a lead pipe 23, which penetrates to the outside of the fermentation tank 1 and is in communication with a carbon dioxide gas tank;

[0053] At present, when fermenting wort, it is necessary to increase the pressure in the tank body during the fermentation process. Increasing the pressure in the tank body can reduce the generation of acetaldehyde, diacetyl and other undesirable flavor substances, and can also accelerate the dissolution of carbon dioxide, reduce the artificial carbonation time. The specific operation is to inject carbon dioxide into the tank body through the externally connected carbon dioxide gas tank. The pressure gauge of the tank body will display the pressure condition in the tank body. When the pressure in the tank body reaches a predetermined size, the air inlet valve of the tank body can be closed. In actual operation, the speed of carbon dioxide dissolving into the wort is limited. For the case of relatively short construction period, it is necessary to improve the carbonation speed to shorten the overall fermentation time. In order to solve the above problems, the present application is provided with a plurality of structures such as the exhaust pipe 3 and the receiving cylinder 22. The specific use process is as follows: when the fermentation tank 1 needs to be pressurized, the carbon dioxide gas tank connected to the lead pipe 23 is opened. There is a gas pump on the carbon dioxide gas tank. Carbon dioxide is injected into the lead pipe 23 through the gas pump. Carbon dioxide gas is injected into the receiving cylinder 22 through the lead pipe 23. The receiving cylinder 22 injects carbon dioxide into the receiving pipe 21. Then carbon dioxide is injected into the exhaust pipe 3 through the receiving pipe 21. As the carbon dioxide content in the exhaust pipe 3 increases, the gas pressure in the exhaust pipe 3 gradually increases. Under the action of the gas pressure, the first blocking block 32 is lifted upwards, stretching the first spring 33. When the first blocking block 32 moves upwards, the first grooves 321 are driven to move upwards synchronously. When the top end of the first grooves 321 moves above the exhaust pipe 3, the exhaust pipe 3 is in communication with the fermentation tank 1 through the first grooves 321. The carbon dioxide gas in the exhaust pipe 3 enters the fermentation tank 1 through the first grooves 321 and directly enters the wort in the fermentation tank 1, fully contacts with the wort, and then moves upwards in the form of bubbles, and finally is discharged to the area above the liquid level of the wort in the fermentation tank 1;

[0054] The carbon dioxide gas content gradually increases in the area above the wort liquid level in the fermenter 1, so the gas pressure in this part gradually increases, thereby accelerating the dissolution rate of carbon dioxide in this part. During the upward movement of carbon dioxide in the form of bubbles from the wort, the contact area between carbon dioxide and wort is large, and the wort exerts pressure on the carbon dioxide, so part of the carbon dioxide will dissolve into the wort during the upward movement, thereby increasing the dissolution rate of carbon dioxide, i.e. the carbonation rate of the wort is increased, thereby shortening the fermentation time and improving the production efficiency of beer in the case of a shorter construction period. Then the staff observes the pressure gauge on the fermenter 1, and when the pressure in the area above the wort liquid level in the fermenter 1 reaches a predetermined size, the injection of carbon dioxide gas into the guide pipe 23 is stopped, and the carbon dioxide gas in the inner part of the exhaust pipe 3 is extracted, so that the gas pressure in the exhaust pipe 3 is reduced, and under the action of the first spring 33, the first blocking block 32 is reset to block the exhaust hole 31. Then after the wort fermentation is completed, the second valve 12 is subsequently opened, the wort in the fermenter 1 is discharged through the second valve 12 and introduced into an external receiving container through the discharge pipe 13, and then subsequent processing is performed. Further, when the carbon dioxide gas moves upward in the form of bubbles, the bubbles will squeeze the first inclined baffle 4, the first inclined baffle 4 will generate a torsional moment under the thrust of the bubbles, and then the first inclined baffle 4 will drive the receiving pipe 21 to rotate, thereby achieving automatic stirring of the wort, which is beneficial to uniform fermentation of the wort.

[0055] The end of the exhaust pipe 3 away from the receiving pipe 21 is provided with a liquid inlet hole 35, the inside of the liquid inlet hole 35 is inserted with a second blocking block 36, a pair of second grooves 361 is formed on the side of the second blocking block 36 away from the receiving pipe 21, a second clamping plate 39 is sleeved on one end of the second blocking block 36 inside the exhaust pipe 3, a second spring 37 is fixedly connected to one side of the second blocking block 36 inside the exhaust pipe 3, and a positioning frame 38 is installed in the exhaust pipe 3 away from the end of the second blocking block 36;

[0056] The end of the first blocking block 32 outside the exhaust pipe 3 is sleeved with a first clamping plate 34;

[0057] During the fermentation of wort, part of the yeast needs to be recovered for later use, and the yeast at the bottom of the fermenter 1 is mixed with sediment and dead yeast, so the yeast discharged through the opening of the second valve 12 needs to be further screened, which is relatively inconvenient; therefore, the structure for obtaining the middle layer yeast in wort is arranged, and the specific operation is as follows: the guide pipe 23 is connected to the liquid pump, and then the liquid pump is started, the liquid pump draws gas through the guide pipe 23 connected to the receiving pipe 21 connected to the receiving cylinder 22, the exhaust pipe 3 connected to the receiving pipe 21 is synchronously drawn by the gas, the gas in the exhaust pipe 3 is drawn out, the gas pressure in the exhaust pipe 3 is reduced, and then negative pressure is generated, under the action of the negative pressure, the first blocking block 32 moves downward, driving the first clamping plate 34 to move downward, and when the first clamping plate 34 is clamped at the top end of the exhaust pipe 3, it stops moving, and at the same time, the second blocking block 36 moves in the direction of the receiving pipe 21 under the action of the negative pressure, and when the second recess 361 moves to the intersection with the liquid inlet hole 35, the exhaust pipe 3 is connected to the fermenter 1 through the second recess 361, and the wort in the fermenter 1 carries the yeast into the exhaust pipe 3, and then is discharged to the outside through the receiving pipe 21, the receiving cylinder 22 and the guide pipe 23, and is received by the container outside, and the exhaust pipe 3 is located at the middle layer position of the wort, and after a certain amount of wort is drawn, the second blocking block 36 is reset under the action of the second spring 37, and the liquid inlet hole 35 is re-sealed, the above process can accurately extract the yeast in the middle layer of the wort, the middle layer yeast has high activity and does not need to be screened, which is convenient for later use;

[0058] It should be noted that during the process of filling carbon dioxide gas into the exhaust pipe 3, the second blocking block 36 is pushed by the gas to move outward from the exhaust pipe 3, and is clamped by the second clamping plate 39 during the movement, so that the liquid inlet hole 35 is continuously blocked when the carbon dioxide gas is injected into the exhaust pipe 3.

[0059] The receiving pipe 21 comprises a base 211, an extension pipe 212 and a top pipe 213; the base 211 is connected to the top end of the receiving cylinder 22, the bottom end of the extension pipe 212 is fixedly connected to the top end of the base 211, the top end of the extension pipe 212 is fixedly connected to the bottom end of the top pipe 213, and the exhaust pipe 3 is fixedly connected to the side surface of the extension pipe 212; the upper and lower ends of the exhaust pipe 3 are symmetrically fixedly connected to a limiting rod 30, the end of the limiting rod 30 away from the exhaust pipe 3 is sleeved with a plug-in cylinder 301, and the end of the plug-in cylinder 301 away from the exhaust pipe 3 is fixedly connected to the side surface of the top pipe 213 and the base 211;

[0060] A pair of supporting plates 302 are fixedly connected to the top end of the exhaust pipe 3 and located on both sides of the limiting rod 30, a brake block 303 is plugged into the top end of the supporting plate 302, one end of the brake block 303 is attached to the side surface of the plug-in cylinder 301, the other end of the brake block 303 is fixedly connected to a pressing spring 304, and a receiving frame 305 is fixedly connected between the end of the pressing spring 304 and the supporting plate 302;

[0061] For the different wort liquid level height, the middle layer position height of wort is different, so the telescopic pipe 212 is arranged, the height of the exhaust pipe 3 can be adjusted by stretching the telescopic pipe 212, and when the height is adjusted, the insertion barrel 301 cooperates with the limiting rod 30 to limit the exhaust pipe 3 to move vertically, and when the height is adjusted, the brake block 303 continuously presses the side of the insertion barrel 301 under the action of the spring 304, and a friction force is generated between the insertion barrel 301, the insertion barrel 301 is kept stable in position height by the friction force.

[0062] As shown in Figures 12 to 17 The side of the receiving pipe 21 is fixedly connected with a pair of connecting rods 5, the end of the connecting rod 5 away from the receiving pipe 21 is fixedly connected with a scraper 51, the scraper 51 is in contact with the inner wall of the fermentation tank 1; when the receiving pipe 21 rotates, the receiving pipe 21 drives the scraper 51 to rotate through the connecting rod 5, the scraper 51 rotates to scrape the inner wall of the fermentation tank 1, and the yeast on the inner wall of the fermentation tank 1 is scraped off, so that the yeast is mixed in the wort, which is beneficial to the uniform fermentation of the wort.

[0063] The fermentation tank 1 includes a cylinder and a cone, the top end of the cone is fixedly connected with the bottom end of the cylinder, the scraper 51 is in contact with the inner wall of the cylinder, the bottom end of the scraper 51 is provided with a drainage groove 53, and the side of the scraper 51 is provided with a through hole 52 penetrating the drainage groove 53;

[0064] The inside of the drainage groove 53 is fixedly connected with a fixing frame 55, the top end of the fixing frame 55 is rotatably connected with a rotating shaft 56, a plurality of liquid blocking plates 57 are annularly fixedly connected to the side of the rotating shaft 56 and located at the same height as the through hole 52, and a plurality of second inclined blocking plates 54 are annularly fixedly connected to the side of the rotating shaft 56 and located below the liquid blocking plates 57;

[0065] When the scraper 51 moves, part of the wort enters the drainage groove 53 through the through hole 52, and then is sprayed downward to the inner wall of the cone through the bottom end of the drainage groove 53, the cone is a conical structure, the yeast deposited on the inner wall of the cone is impacted by the wort sprayed by the drainage groove 53, so that the yeast is prevented from continuously depositing on the inner wall of the cone and hardening and clogging the outlet; further, when the wort enters the inside of the drainage groove 53, the wort impacts the liquid blocking plates 57 on the side of the rotating shaft 56, the liquid blocking plates 57 drive the rotating shaft 56 to rotate, the rotating shaft 56 drives the second inclined blocking plates 54 on the side to rotate, and the second inclined blocking plates 54 rotate to accelerate the downward movement of the wort in the drainage groove 53, thereby improving the impact effect of the wort sprayed by the drainage groove 53 on the inner wall of the cone, and further preventing the yeast from depositing and clogging; it should be noted that the vertical boundary of the rotating shaft 56 and the through hole 52 is aligned, so that the wort entering the drainage groove 53 can only impact the liquid blocking plates 57 on one side of the rotating shaft 56, and the liquid blocking plates 57 at different positions on the rotating shaft 56 are prevented from being simultaneously impacted by the wort, so that the rotating shaft 56 is difficult to rotate due to force cancellation.

[0066] A spray head 6 is fixedly connected to the inner top wall of fermentation tank 1. A water pipe is connected to the outside of the spray head 6. A connecting spring 60 is fixedly connected to the bottom end of the spray head 6. A water spray cylinder 61 is fixedly connected to the bottom end of the connecting spring 60. The bottom end of the water spray cylinder 61 has multiple spray holes 611 arranged in a ring shape. The bottom end of the water spray cylinder 61 is at the same height as the top end of the receiving pipe 21. A sealing block 62 is inserted into the top end of the receiving pipe 21. A buffer spring 63 is fixedly connected to the bottom end of the sealing block 62. A mounting bracket 64 is fixedly connected to the bottom end of the buffer spring 63. The mounting bracket 64 is fixed to the inner wall of the receiving pipe 21. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) At this time, the water pipe connected to the spray head 6 is connected to the water pump. The water pump draws cleaning solution and injects it into the spray head 6. Then, it is sprayed out through the spray head 6 to flush the inside of the fermentation tank 1. The cleaning solution sprayed out by the spray head 6 will act on the surface of the first inclined baffle 4, causing the first inclined baffle 4 to drive the receiving pipe 21 to rotate. The receiving pipe 21 drives the scraper 51 to rotate through the connecting rod 5. The rotation of the scraper 51 scrapes off the residue on the inner wall of the fermentation tank 1, improving the cleaning effect. In addition, the cleaning solution sprayed out by the spray head 6 will impact the water spray cylinder 61, driving the water spray... The cylinder 61 is stretched and connected to the spring 60, moving downwards and pressing the sealing block 62 downwards. Then, the bottom end of the spray cylinder 61 is inserted into the receiving pipe 21. The cleaning fluid entering the spray cylinder 61 is sprayed out through the spray hole 611, flushing the inner wall of the receiving pipe 21. Simultaneously, the inlet pipe 23 is intermittently blocked, causing the cleaning fluid to intermittently fill the receiving pipe 21 and the vent pipe 3. The cleaning fluid pushes up the first blocking block 32 at the top of the vent pipe 3, opening the vent hole 31, and the cleaning fluid is sprayed out through the vent hole 31, along with the inlet pipe 23... Intermittent sealing of the pipe opening allows the cleaning solution to be discharged from either the inlet pipe 23 or the vent hole 31, thus cleaning the inside of the receiving pipe 21, the vent pipe 3, and the receiving cylinder 22. Furthermore, a sealing ring 7 is fixedly connected to the top of the receiving pipe 21, and the bottom end of the spray pipe 61 passes through the sealing ring 7 and blocks the spray hole 611. During the wort fermentation process, the sealing ring 7 blocks the spray hole 611 at the bottom of the spray pipe 61, preventing carbon dioxide from entering the spray hole 611 inside the fermentation tank 1 and affecting the fermentation process, such as the pressurization process of the fermentation tank 1.
