Description

Technical Field

[0001] This utility model relates to the field of beer storage equipment, and in particular to an inner bag type beer storage device. Background Technology

[0002] After beer fermentation matures, the fermentation liquid contains yeast, solidified matter, and other turbid substances, which need to be removed by filtration. The filtered beer is clear and transparent; this stage of the liquid is called "sake." Before being supplied to the packaging workshop or bottling, the sake needs to be stored and preserved in sake storage containers. These storage containers serve as transitional equipment before the sake becomes the finished product. To prevent the taste of the sake from being compromised, existing sake storage containers require a large amount of carbon dioxide for pressurization. During bottling, the pressure inside the container is increased to about 1 bar. Furthermore, the sake storage containers must be cleaned and sterilized according to regulations before and after use.

[0003] Using existing sake storage containers for storing and storing sake has at least the following drawbacks:

[0004] 1. The carbon dioxide used to pressurize sake tanks may affect the carbon dioxide content in the sake, thus affecting its taste.

[0005] Second, a large amount of carbon dioxide is needed to pressurize the tank, and after the liquid is emptied, the carbon dioxide needs to be released, which greatly increases the cost and has a significant impact on the environment.

[0006] Third, sake jars need to be cleaned and disinfected with a large amount of CIP solution before and after each use. If there is any CIP solution residue, it will be harmful to the human body and increase the cost significantly.

[0007] Fourth, sake jars have a complex structure and many hard-to-clean areas, which can easily lead to bacterial growth.

[0008] 5. The sake jar cannot be moved and is only suitable for specific scenarios. Summary of the Invention

[0009] In view of this, the technical problem to be solved by this utility model is to provide an inner bag type beer storage device, which at least solves one of the problems existing in the background art. The pressurized air inside the storage device does not come into contact with the beer, ensuring that the standard carbon dioxide content in the beer is maintained, the taste of the beer is not affected, and the temperature and quality of the beer are guaranteed.

[0010] To solve the above-mentioned technical problems, the technical solution of this utility model is: an inner bag type beer storage device, the inner bag type beer storage device comprising: an inner cylinder body disposed on a frame, an inner bag disposed in the inner cavity of the inner cylinder body for holding beer, a compressed air system for supplying compressed air to the inner cavity of the inner cylinder body, and a refrigeration system for adjusting the temperature of the beer in the inner bag.

[0011] The following are several further improvements to the inner bag type beer storage device of this utility model:

[0012] The inner bag is provided with an inlet / outlet interface for wine, and the bottom of the inner cylinder is fixedly provided with a cylinder inlet / outlet pipe. One end of the wine valve passes through the cylinder inlet / outlet pipe and is connected to the inlet / outlet interface for wine in the inner bag, and the other end of the wine valve is used to connect to the wine delivery pipe.

[0013] The refrigeration system includes a refrigeration unit mounted on the frame and a refrigerant jacket mounted on the outer periphery of the inner cylinder. The refrigerant jacket is connected to the refrigeration unit via refrigerant piping.

[0014] The inner cylinder is equipped with a temperature sensor, which is electrically connected to the refrigeration unit.

[0015] The compressed air system includes an intake valve, an exhaust valve, and an air compressor. The intake valve and the exhaust valve are located at one end of the inner cylinder and are connected to the inner cavity of the inner cylinder. The intake valve is connected to the air compressor through an air supply pipeline. The air compressor is mounted on the frame.

[0016] The compressed air system also includes a mechanical pressure regulating valve and a pressure gauge located at one end of the inner cylinder.

[0017] A manhole is provided at one end of the inner cylinder.

[0018] A viewing mirror is provided at one end of the inner cylinder.

[0019] The frame is equipped with casters at the bottom.

[0020] The inner cylinder is horizontally arranged with one unit; or, the horizontally arranged inner cylinder is arranged with two or more units vertically.

[0021] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0022] This utility model's inner-bag beer storage device includes an inner cylinder, an inner bag disposed within the inner cavity of the inner cylinder for holding the beer, a compressed air system for supplying compressed air to the inner cavity of the inner cylinder, and a refrigeration system for regulating the temperature of the beer in the inner bag. When storing and holding sake, since the beer is stored in the inner bag and does not come into contact with outside air, the inner cavity of the inner cylinder can be pressurized using compressed air, which greatly saves costs and produces no carbon dioxide emissions, thus having no environmental impact and being more environmentally friendly, in line with current technological development trends. Because the beer is stored in the inner bag and does not come into contact with outside air, the inner cylinder can be pressurized using compressed air, greatly saving costs and producing no carbon dioxide emissions, thus having no environmental impact and being more environmentally friendly, in line with current technological development trends. The air contact between the inner bag and the outside ensures the standard carbon dioxide content in the beer, without affecting its taste. The refrigeration system can regulate and maintain the beer within a set temperature range, ensuring taste and quality. After the beer is emptied, the inner bag can be replaced directly without the need to clean and disinfect the inner cylinder with CIP solution, preventing contact between harmful liquids and the inner cylinder, making it safer and more hygienic. This utility model of an inner bag-type beer storage device has a simple structure, is easy to clean, has no dead corners, and is not prone to bacterial growth. When equipped with casters at the bottom of the frame, it can be moved and is suitable for various scenarios. Attached Figure Description

[0028] It should be noted that, in this description, unless otherwise specified or limited, the terms “connected,” “linked,” “interconnected,” etc., should be interpreted broadly, and can refer to a direct connection between two components or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] The embodiments of this utility model will now be described in further detail and without limitation, with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown in the figure, the inner bag type beer storage device of this utility model includes: a frame (for ease of manufacturing and assembly, the frame specifically includes a lower support 2 and an upper support 11 that are fixed together by bolts to form an upper and lower stack, saving space), an inner cylinder 17 arranged horizontally on the frame (optimized design is that the bottom of the inner cylinder 17 is set on the lower support 2 through a saddle 15 to ensure the stability of the structure), an inner bag 19 for holding beer is provided in the inner cavity of the inner cylinder 17, and the inner bag type beer storage device also includes a compressed air system for supplying compressed air to the inner cavity of the inner cylinder 17, and a refrigeration system for adjusting the temperature of the beer in the inner bag 19.

[0032] The inner bag 19 is provided with an inner bag inlet / outlet wine interface (not specifically marked in the figure). The bottom of the inner cylinder 17 is provided with a cylinder through hole. The bottom of the cylinder through hole is welded with a cylinder inlet / outlet wine pipe 4. One end of the wine valve 3 passes through the cylinder inlet / outlet wine pipe 4 and is connected to the inner bag inlet / outlet wine interface. The other end of the wine valve 3 is used to connect to one end of the wine delivery pipe 20. The other end of the wine delivery pipe 20 can be connected to the wine column 18, where wine can be collected.

[0033] The refrigeration system includes a refrigeration unit 13 mounted on a frame (preferably an upper support 11) and a refrigerant jacket 16 disposed on the outer periphery of the inner cylinder 17. The refrigerant jacket 16 is connected to the refrigeration unit 13 via a refrigerant pipeline 21. A temperature sensor 14 is disposed in the inner cylinder 17 and is electrically connected to the refrigeration unit 13.

[0034] The compressed air system includes an intake valve 5, an exhaust valve 6, and an air compressor 12. The intake valve 5 and exhaust valve 6 are located on the end cap of one end of the inner cylinder 17 (defined as the operating end) and are connected to the inner cavity of the inner cylinder 17. The intake valve 5 is connected to the air compressor 12 through an air supply pipeline 22. The air compressor 12 is mounted on a frame (preferably an upper support 11). The compressed air system further includes a mechanical pressure regulating valve 10 and a pressure gauge 8 located on the end cap of the operating end of the inner cylinder 17.

[0035] The inner cylinder 17 is equipped with a manhole 7 on the operating end cap, which is optimized to be an elliptical manhole for personnel to enter and exit the equipment for installation, maintenance and safety inspection. The inner cylinder 17 is also equipped with a sight glass 9 on the operating end cap to facilitate observation of the liquid in the inner bag 19 inside the inner cavity of the inner cylinder 17. The sight glass can be made of glass or transparent plastic.

[0036] In this embodiment, a movable caster 1a can also be installed at the bottom of the frame (i.e., the bottom of the lower bracket 2) to facilitate the movement of the entire device, which is very suitable for various scenarios such as outdoor picnics and dining.

[0037] The process of storing and holding sake using the inner bag type beer storage device of this utility model embodiment is as follows:

[0038] First, open the oval manhole 7 and disinfect it by spraying alcohol on the manhole 7 and its surroundings, the inner surface of the inner cylinder 17, and the welded joint between the inlet / outlet wine connector 4 and the cylinder. Next, place the inner bag 19 inside the inner cylinder 17, insert the inner bag's inlet / outlet wine connector into the cylinder's inlet / outlet wine connector 4, insert one end of the wine valve 3 through the cylinder's inlet / outlet wine connector 4 into the inner bag's inlet / outlet wine connector and secure it, close the manhole 7, adjust the mechanical pressure regulating valve 10 to the required pressure inside the cylinder, open the air inlet valve 5, and use the air compressor 12 to pressurize compressed air through the air supply line 22 into the space between the inside of the inner cylinder 17 and the outside of the inner bag 19 until the required pressure is reached, then close the air inlet valve 5. This completes the preparation work before adding the wine. When filling the container with liquor, open the liquor valve 3 to force the liquor into the inner bag 19. At this time, the air in the inner cylinder 17 is slowly discharged through the mechanical pressure regulating valve 10. When discharging the liquor, the air inlet valve 5 must be kept open. As the liquor is discharged through the liquor column 18, the pressure inside the cylinder decreases. When the air compressor 12 detects that the pressure inside the cylinder is lower than the set pressure, the air compressor 12 will pressurize the cylinder with compressed air to maintain dynamic balance inside the cylinder. When the liquor in the inner bag 19 is emptied, close the air inlet valve 5 and open the exhaust valve 6 to discharge the air inside the cylinder until the pressure inside the cylinder drops to atmospheric pressure. Open the manhole 7, remove the liquor valve 3 and clean it. Finally, remove the inner bag 19 from the inner cylinder 17.

[0039] When the wine enters or exits the inner bag 19, the condition of the wine inside can be observed through the sight glass 9; the pressure gauge 8 can detect the pressure inside the cylinder in real time; the temperature sensor 14 can sense the temperature of the wine in the inner bag 19 in real time, and adjust the temperature of the wine by introducing refrigerant through the refrigeration unit 13 and the refrigerant jacket 16, so as to maintain the wine within the set temperature range and ensure the taste and quality.

[0040] Example 2

[0041] like Figure 3 As shown, the inner bag type beer storage device of Embodiment 2 is basically the same in structure and principle as that of Embodiment 1. The difference is that there are two horizontally arranged inner cylinders 17, one above the other, which can share one air compressor (not specifically shown in the figure) and one refrigeration unit (not specifically shown in the figure). Of course, depending on actual needs, while ensuring the stability and ease of use of the device, there can be more than two inner cylinders 17, such as three or more. The arrangement of multiple inner cylinders 17 vertically can greatly save floor space.

[0042] An adjustable foot 1b is provided at the bottom of the lower bracket 2, which is mainly used in bars and other places where it is not necessary to move the equipment.

[0043] Obviously, the adjustable foot 1b can also be replaced with a movable caster, so that the device can be moved to meet the need for mobility.

[0044] In summary, the inner bag beer storage device of this utility model embodiment can use compressed air for pressurization, saving carbon dioxide and causing no environmental impact; the beer does not come into contact with carbon dioxide, ensuring the standard carbon dioxide content in the beer and not affecting its taste; the refrigeration system can adjust and maintain the beer within a set temperature range, ensuring taste and quality; the inner bag can be replaced directly after the beer is emptied, making it safer and more hygienic; the structure is simple, easy to clean, has no dead corners, and is not prone to bacterial growth; it can be moved and is suitable for various scenarios.
