Description

Technical Field

[0001] This utility model belongs to the technical field of brewing equipment, specifically relating to an oak barrel flavor compensation device. Background Technology

[0002] Oak barrels are a core tool in the brewing and aging process of wine, whiskey, brandy and other spirits. Their history can be traced back thousands of years, and they represent a perfect combination of brewing techniques and wood science.

[0003] In traditional winemaking, the flavor contribution of oak barrels has always been a challenge for winemakers. During aging, oak barrels gradually lose their ability to release flavor compounds into the wine, typically reaching a state of equilibrium after 3-4 years of use, at which point they no longer add flavor to the wine.

[0004] Traditional repair methods usually require disassembling the barrel lid, reworking the inner wall of the barrel, or replacing some of the boards. However, this method is not only cumbersome, but may also cause the barrel wall to become thinner, eventually rendering the oak barrel unusable. Utility Model Content

[0005] The purpose of this invention is to provide an oak barrel flavor compensation device that avoids the limitations of traditional maintenance methods, is easier to operate, can significantly extend the service life of oak barrels, and ensures flavor replenishment during the brewing process.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An oak barrel flavor compensation device includes several oak planks stacked in parallel. The ends of adjacent oak planks are alternately connected by hinge shafts, allowing them to extend in a straight line. Each of the stacked oak planks has a weight fixedly installed at the same end to allow it to sink in the wine.

[0008] As a preferred option, the oak planks need to be air-dried in the open air and lightly baked before being made into strips.

[0009] As a preferred embodiment, the oak board is capable of rotating 360° around the hinge axis, and the hinge axis is made of stainless steel or oak.

[0010] As a preferred embodiment, the weight plate has an integrally formed threaded rod that is threaded to the end of the oak board, or the weight plate has a hole and is bolted to the end of the oak board by a flexible connector.

[0011] As a preferred embodiment, the density of the pendant is greater than that of the liquor, and it is made of stainless steel. The pendant is spherical or other cubic shape.

[0012] As a preferred embodiment, one end of the compensation device is provided with a flexible connector for connecting to the barrel plug on the oak barrel, the flexible connector being a stainless steel chain or a steel wire rope.

[0013] As a preferred embodiment, the oak board is provided with uniformly distributed through holes, which are circular or other regular polygons.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention connects several oak planks sequentially using hinges, allowing them to extend and straighten in a straight line during use. They are then gradually placed into the oak barrel and folded back, making storage convenient. Furthermore, multiple compensation devices can be placed in a single oak barrel, avoiding the limitations of traditional repair methods. The operation is also simpler, significantly extending the service life of the oak barrel.

[0016] This invention, by incorporating a weighted support, allows the compensation device to sink into the wine after being placed inside the oak barrel, ensuring full contact with the wine. A flexible connector at the end of the compensation device facilitates easy removal from the barrel when needed and prevents it from detaching during use. Therefore, installation and removal of the device can be completed without opening the barrel end cap, simply by using the flexible connector on the barrel stopper, making operation simple and convenient. Even in confined spaces, operation can be easily accomplished. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] Example 1:

[0025] like Figures 1-3 As shown, an oak barrel flavor compensation device consists of several oak planks 1, which are stacked in parallel and then connected at both ends by a hinge shaft 2 in an alternating rotation, so that it can be folded or extended and straightened in a straight line.

[0026] Each oak plank 1 is meticulously designed in size and shape. In this embodiment, the oak is air-dried in the open air for 18-36 months after felling to reduce the wood's moisture content to approximately 16%. During this process, hydrolyzable tannins such as ellagitannins are gradually degraded under the action of oxygen and microorganisms, generating soluble small-molecule tannins and reducing bitterness. Simultaneously, the oxidative decomposition of lignin produces acetaldehyde and phenolic substances, promoting an increase in vanillin content (especially within the plank), ensuring the even release of flavor compounds in the wine. The surface of the oak plank 1 undergoes this special treatment, allowing for better contact with the wine and the release of flavor components such as tannins and vanillin.

[0027] By replenishing flavor compounds, the oak barrel 5 can continue to function after 3-4 years of use, preventing it from becoming unusable due to thinning of the barrel walls. This device can significantly extend the lifespan of the oak barrel 5 and reduce brewing costs.

[0028] Secondly, the flavor compounds from the oak plank 1 are evenly released into the wine, enhancing its color stability, smoothness, and aroma harmony. Compared to traditional methods, this device can add flavor to the wine more efficiently.

[0029] It should be noted that the dimensions of each oak plank 1 need to be designed according to the diameter of the oak barrel 5, generally not exceeding its inner diameter, and can also be designed in a rod shape as needed. This allows the device to be scientifically configured according to the inner surface area of ​​the oak barrel 5, meeting the needs of oak barrels 5 of different capacities. It is suitable for both small and large oak barrels 5.

[0030] Please refer to the appendix for details. Figure 1 The oak planks 1 are connected by a hinge shaft 2 perpendicular to the oak planks 1, allowing the oak planks 1 to rotate 360° around the shaft. This design allows the compensation device to be straightened when entering the oak barrel 5, and to be folded and retracted inside the barrel, facilitating the placement of multiple devices and reducing the space occupied inside the barrel.

[0031] Furthermore, in this embodiment, the hinge shaft 2 is made of 316 stainless steel to ensure its structural strength and connection stability. Of course, in other embodiments, other food-grade stainless steel or oak can be used, as long as the oak board 1 can rotate 360° around the shaft; if oak is used, the overall integrity of the compensation device is stronger, and its main body can be fully utilized to supplement the flavor of the wine.

[0032] Please refer to the appendix for details. Figure 3 To ensure the compensating device is stably submerged in the wine, each oak plank 1 has a weight 3 at one end. This weight 3 has a density greater than that of the wine and is typically made of 316 stainless steel (though other materials with a density greater than that of the wine can also be used). The purpose of the weight 3 is to ensure that the compensating device stands vertically inside the oak barrel 5, thereby allowing the oak plank 1 to better contact the wine and release flavor compounds evenly.

[0033] It should be noted that the end of the sinker 3 is the same end where the oak planks 1 are stacked, and it is also the end of the compensation device. In this way, when the oak planks 1 are placed into the oak barrel 5, the sinker 3 can sink them by its own weight and thus place them vertically and stably inside the oak barrel 5.

[0034] Furthermore, in this embodiment, the pendant 3 has a threaded rod integrally formed on it and threadedly connected to the end of the oak board 1, and the pendant 3 is spherical. Of course, in some other embodiments, holes can be made in the pendant 3, and then it can be fastened to the end of the oak board 1 by a flexible connector (stainless steel chain or wire rope); at the same time, the pendant 3 can be other cubic shapes.

[0035] Please refer to the appendix for details. Figure 3 One end of the compensation device is connected to the barrel plug 6 via a flexible connector (such as a 316 stainless steel chain or wire rope). The flexible connector is designed to facilitate pulling the device out of the barrel and also prevents the device from falling off during use. This allows the device to be installed and removed without opening the barrel end cap, simply by using the flexible connector on the barrel plug 6, making operation simple and convenient. Even in confined spaces, operation can be easily completed.

[0036] It should be noted that the flexible connectors are connected to the oak board 1 and the barrel plug 6 in two ways: either by direct bolting or by bolting to screws and then fixing them.

[0037] Example 2:

[0038] like Figures 1-4 As shown, an oak barrel flavor compensation device is basically the same as that in Embodiment 1, except that:

[0039] The oak board 1 has uniformly distributed through holes 4, and the through holes 4 are regular hexagons. The through holes 4 allow the interior of the oak board 1 to better contact the wine, increase the contact area, and thus improve the release efficiency of flavor substances. At the same time, it can reduce the impact of the compensation device placed in the oak barrel 5 on the flow of the wine and reduce the flow resistance.

[0040] The specific usage method is as follows:

[0041] I. Installation Steps:

[0042] 1. Inspection device

[0043] Before installation, carefully inspect the quality of each oak plank to ensure its surface is free of defects and that the baking or carbonization treatment meets requirements. Replace any damaged oak planks promptly if any problems are found to ensure the performance of the installation.

[0044] It is worth noting that this installation method allows for direct observation of the quality of each oak plank, facilitating the removal of defective planks and ensuring the quality of the installation. Furthermore, the device's simple structural design makes it easy to maintain and replace parts.

[0045] 2. Straightening device

[0046] Straighten the compensation device so that all the oak planks 1 are unfolded and form a straight line. Ensure that the device is not stuck or deformed when straightened so that it can be smoothly inserted into the bucket.

[0047] 3. Insertion device

[0048] Slowly insert the straightened device into the opening of oak barrel 5 until it is fully inside. Handle with care to avoid damaging the oak plank 1.

[0049] 4. Folding device

[0050] Once the device is inside the barrel, the oak plank 1 automatically folds and contracts to form a compact structure, facilitating the placement of multiple devices inside the barrel. At this point, the device should stand vertically at the bottom of the barrel, with the weight 3 ensuring its stability.

[0051] 5. Sealed wine barrels

[0052] After adding the alcohol, install the barrel plug 6 at the opening, ensuring a good seal. At this point, the flexible connector has connected the barrel plug 6 to the device, securing the device in place. The flexible connector prevents the device from shifting or falling off during use.

[0053] II. Usage process:

[0054] 1. Pour the wine into

[0055] After placing the compensating device inside oak barrel 5, pour the wine into the barrel. Due to the weights 3, the oak planks will stand vertically in the wine, ensuring full contact. Ensure the device is completely submerged for optimal flavor enhancement.

[0056] 2. Flavor Release

[0057] When oak planks are soaked in the wine, the flavor compounds on their surface (such as tannins and vanillin) gradually dissolve into the wine, enhancing its flavor and aroma. The effect of this flavor enhancement varies depending on the type of wine and the aging time, and usually becomes apparent within a few weeks.

[0058] It is important to note that during use, avoid shaking the oak barrel 5 violently, as this may affect the stability of the device. If you need to move the oak barrel 5, please remove the device first.

[0059] 3. Regular inspections

[0060] During use, periodically pull out the device via the flexible connector to check the condition of the oak board 1 and ensure it is functioning properly. It is recommended to check monthly, including the integrity of the oak board 1, any surface damage, and whether the device is loose. Also, ensure the barrel plug 6 is properly sealed to prevent leakage. If the barrel plug 6 is found to be leaking, replace the seal immediately.

[0061] III. Demolition Steps

[0062] 1. Pull-out device

[0063] Open stopper 6 and slowly pull the device out of the container using the flexible connector. Maintain a steady hand during operation to avoid damaging the device or the container.

[0064] 2. Cleaning device

[0065] Clean the liquid off the apparatus and inspect the oak plank 1 for damage or if it needs to be replaced. If the oak plank 1 is damaged, replace it promptly to ensure the performance of the apparatus.

[0066] 3. Storage device

[0067] Store the device properly in a dry, clean environment for future use. It is recommended to store the device on a dedicated storage rack to prevent moisture or damage from external forces.

[0068] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
