Description

Technical Field

[0001] This utility model relates to the field of beer production technology, specifically to an automatic beer yeast addition and mixing device. Background Technology

[0002] Beer is a fermented beverage made primarily from malt and water, with the addition of hops (including hop products), and fermented with yeast. It contains carbon dioxide and can form foam. In the beer production process, yeast is required. The yeast is mixed with wort, and the mixture is fermented in a fermentation tank. When mixing yeast and wort, an automatic yeast addition and mixing device is required.

[0003] When using yeast, add yeast powder to sterile water to activate it. After slowly stirring, form a yeast suspension. Then add the yeast suspension to the wort to allow the yeast and wort to mix and come into contact fully. When the yeast and wort come into contact, inject sterile air to improve the mixing effect.

[0004] Traditional brewer's yeast addition involves directly adding the yeast suspension and wort into the fermentation tank. Although the mixture is stirred inside the fermentation tank, it is difficult to achieve both yeast activity and uniformity. To address this, we propose an automated brewer's yeast addition and mixing device. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic beer yeast addition and mixing device, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an automatic brewing and mixing device for beer yeast, comprising: A fermenter, wherein a stirring assembly is provided inside the fermenter and a discharge pipe is provided on the lower outer side of the fermenter; The mixing and adding mechanism includes a mixing tank fixedly connected to the top of the fermentation tank. A transmission rod is movably connected to the inner side of the mixing tank via a bearing. A fan blade is provided on the outer side of the transmission rod. A wort delivery pipe and a yeast suspension delivery pipe are provided on the outer side of the mixing tank. A diversion valve is provided in the middle of the yeast suspension delivery pipe. A diversion pipe communicating with the wort delivery pipe is installed at the diversion port of the diversion valve. The gas delivery mechanism includes a gas delivery pipe extending into the interior of the fermenter, with multiple branch pipes fixedly connected to the outside of the gas delivery pipe and communicating with the interior of the gas delivery pipe, and gas outlets opened on the outside of the branch pipes.

[0007] Preferably, a stirring rod is fixedly connected to the outside of the transmission rod, and the stirring rods are evenly distributed on the outside of the transmission rod.

[0008] Preferably, a fixed rod distributed in a ring is fixedly connected to the outside of the transmission rod, and the fan blade is fixedly connected to the fixed rod in an inclined shape.

[0009] Preferably, the bottom of the mixing tank is fixedly connected to a connecting pipe that communicates with the inside of the mixing tank, and the other end of the connecting pipe passes through the outside of the fermentation tank and extends into the inside of the fermentation tank.

[0010] Preferably, a filter is installed at the end of the gas supply pipe away from the fermenter, and the air inlet of the filter is fixedly connected to an air inlet pipe.

[0011] Preferably, the top of the fermenter is provided with an exhaust port for venting the fermenter.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, through the setting of the mixing and adding mechanism, allows the yeast suspension and wort to be mixed in the mixing tank before entering the fermentation tank. As the wort is injected, the fan blades can drive the transmission rod to rotate, and the external stirring rod can be used to stir the yeast suspension and wort, so that they are quickly mixed.

[0013] 2. This utility model, through the setting of a wort delivery pipe, a diversion valve, a diversion pipe and a yeast suspension delivery pipe, allows yeast to be injected into the wort delivery pipe and directly into the mixing tank in a certain proportion during yeast injection. This allows a small portion of the yeast suspension to be mixed with the wort in advance to accelerate fermentation, while the majority of the yeast suspension is directly injected into the mixing tank. By adopting the above-mentioned segmented addition method, the contradiction between yeast activity protection and mixing efficiency can be effectively balanced.

[0014] 3. Through the setting of the gas delivery mechanism, after the yeast suspension and wort enter the fermentation tank, the filtered sterile gas can be injected into the fermentation tank in a timely manner from different depths of the mixed liquid, ensuring that the sterile gas is in uniform contact with the mixed liquid, which helps to improve the fermentation quality and efficiency of the mixed liquid.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments. Example 1:

[0020] Reference Figure 1-3 This is the first embodiment of the present invention, which discloses an automatic brewing and mixing device for beer yeast, comprising: Fermentation tank 1, with a stirring component 2 inside for stirring the mixed liquid during fermentation, and a discharge pipe 3 on the lower outer side of fermentation tank 1 for discharging materials after fermentation. The mixing and adding mechanism 5 includes a mixing tank fixedly connected to the top of the fermentation tank 1 for mixing yeast suspension and wort. A transmission rod is movably connected to the inside of the mixing tank via a bearing. A fan blade is provided on the outside of the transmission rod. A wort delivery pipe and a yeast suspension delivery pipe are provided on the outside of the mixing tank. A diversion valve is provided in the middle of the yeast suspension delivery pipe. A diversion pipe connected to the wort delivery pipe is installed at the diversion port of the diversion valve, so that a small portion of the yeast suspension (about 30%) can be pre-injected into the wort delivery pipe through the diversion pipe for preliminary mixing with the wort.

[0021] Specifically, a fixed rod 509 arranged in a ring is fixedly connected to the outside of the transmission rod 507, and the fan blade 508 is fixedly connected to the fixed rod 509 in an inclined manner.

[0022] During operation, the wort flow, which has been premixed with some yeast and discharged from the wort delivery pipe 506, impacts the inclined fan blade 508 under its own potential energy, driving the fan blade 508 to rotate.

[0023] Specifically, a stirring rod 510 is fixedly connected to the outside of the transmission rod 507, and the stirring rods 510 are evenly distributed on the outside of the transmission rod 507.

[0024] The rotation of the fan blade 508 drives the transmission rod 507 to rotate, which in turn drives the stirring rod 510 to rotate inside the mixing tank 501, powerfully agitating the liquid inside. At the same time, the combined effect of the rotation of the fan blade 508 and the agitation of the stirring rod 510 creates a turbulent flow in the liquid inside the mixing tank 501, significantly improving the uniformity and efficiency of mixing approximately 70% of the yeast suspension that subsequently enters the mixing tank 501 with the wort.

[0025] Specifically, a connecting pipe 503 is fixedly connected to the bottom of the mixing tank 501 and communicates with the inside of the mixing tank 501. The other end of the connecting pipe 503 passes through the outside of the fermentation tank 1 and extends into the inside of the fermentation tank 1.

[0026] The yeast-wort mixture, after being efficiently mixed, flows through the connecting pipe 503 into the fermentation tank 1 below, ready for fermentation. Example 2:

[0027] Reference Figure 1-2 and Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The gas delivery mechanism 4 includes a gas delivery pipe 404 extending into the fermenter 1. Multiple branch pipes 405 that communicate with the inside of the gas delivery pipe 404 are fixedly connected to the outside of the gas delivery pipe 404. Gas outlets 406 are opened on the outside of the branch pipes 405.

[0028] This mechanism is used to deliver sterile air or other process gases to different locations within the fermenter 1 during the fermentation stage. The gas is distributed to each branch pipe 405 via the gas supply pipe 404, and finally blown evenly and at multiple points into the mixed liquid at the bottom of the fermenter 1 through the gas outlet 406 on the branch pipe 405.

[0029] Specifically, a filter 403 is installed at the end of the gas supply pipe 404 away from the fermenter 1 to sterilize and filter the incoming gas, ensuring that the gas entering the fermenter 1 is sterile and preventing contamination of the fermentation liquid. The air inlet of the filter 403 is fixedly connected to an air inlet pipe 402 for connecting to an external sterile gas source.

[0030] Specifically, the top of the fermenter 1 is provided with an exhaust port 401 for venting the fermenter 1.

[0031] It is used to maintain a suitable pressure inside the tank during gas introduction and fermentation gas production, and to discharge gases such as carbon dioxide produced.

[0032] The remaining structure is the same as that in Example 1.

[0033] The workflow of this utility model is as follows: During the beer brewing process, when yeast is added, the yeast suspension is transported through the yeast suspension delivery pipe 502. Under the action of the diversion valve 504, the yeast suspension is divided into 30 / 70. A small portion of the yeast suspension enters the wort delivery pipe 506 through the diversion valve 504 and the diversion pipe 505 to be pre-mixed with the wort inside. Most of the yeast suspension is directly transported to the mixing tank 501 through the yeast suspension delivery pipe 502. When the pre-mixed yeast and wort are discharged from the wort delivery pipe 506, their potential energy drives the fan blade 508 to rotate. The rotation of the fan blade 508 drives the transmission rod 507 to rotate, and the rotation of the transmission rod 507 drives the stirring rod 510 to rotate, thus stirring the mixed liquid in the mixing tank 501. When the mixed liquid impacts the fan blade 508 and the drive rod 507 rotates, turbulence is formed inside the mixing tank 501, which achieves the purpose of improving the mixing effect of yeast suspension and wort. After mixing, the liquid mixture enters the fermenter 1 through the connecting pipe 503 for fermentation. At this time, sterile gas enters through the air inlet pipe 402. After being filtered by the filter 403, it is blown into the fermenter 1 from different positions through the delivery pipe, branch pipe 405, and air outlet 406. This, together with the stirring component 2, allows the liquid mixture to come into uniform contact with the sterile air, thereby improving the fermentation quality and efficiency of the liquid mixture.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
