A multi-path fresh beer filling system

Abstract

This invention discloses a multi-channel fresh beer bottling system, comprising a sealed container for holding the beer, a bottling assembly, and a control center. A storage tank is disposed between the sealed container and the bottling assembly. The sealed container, storage tank, and bottling assembly are all connected to gas supply pipelines. The control center adjusts the pressure of the sealed container, storage tank, and bottling assembly by controlling the connection status of each gas supply pipeline, creating a pressure difference between them. Under the influence of this pressure difference, the beer flows from the sealed container through the storage tank and then into the bottling assembly. During the beer settling process, the gas pressure inside the storage tank remains stable. This invention uses a storage tank between the bottling bottle and the sealed container to temporarily store a portion of the beer before it enters the bottling process. The stable gas pressure inside the storage tank allows for the dissolution of gas on the surface of the beer, eliminating foaming caused by insufficient pressure. It also ensures that liquid near the liquid outlet of the sealed container can be fully utilized, thereby reducing waste and lowering operating costs.

Description

Technical Field

[0001] This invention relates to the field of automated vending equipment technology, and more specifically, to a multi-channel fresh beer bottling system. Background Technology

[0002] As living standards improve, people increasingly seek better-tasting and more diverse drinking experiences. Beer, as one of the most widely consumed beverages, boasts a large customer base. To meet these rising demands, craft beer is gradually entering commercial operation. To maintain the taste and flavor advantages of craft beer, its operation requires a certain amount of manpower, which increases operating costs. Therefore, with the rapid development of automation and intelligence, various automated beer vending machines are being installed at various locations. This significantly reduces manual operation to simply changing the brewed beer in the machines, ensuring both freshness and taste while providing convenience for customers and merchants. This technology is gradually being adopted by various craft beer vending machines.

[0003] However, in existing vending machines, craft beer is placed in sealed containers and drawn out through a dispensing tube for bottling. As the liquid level in the sealed container decreases, the internal pressure drops, and the gas dissolved in the craft beer gradually precipitates out, forming hop foam at the liquid surface. When the liquid level in the sealed container drops to near the bottom of the dispensing tube, the liquid-gas mixture in the part of the container that the dispensing tube contacts becomes severely mixed. If the dispensing tube directly draws out this portion of liquid for bottling, on the one hand, the actual liquid content in this portion is insufficient, resulting in substandard craft beer; on the other hand, the excessive pressure inside the bottling bottle during the bottling process can easily cause overflow, contaminating the bottling equipment and increasing cleaning and equipment costs. Therefore, in existing equipment, the dispensing section of the bottling equipment is generally no lower than the bottom of the dispensing tube, directly causing a significant waste of craft beer. Furthermore, some dispensing tubes are angled at the bottom for easy dispensing, further increasing waste. According to statistics, the final wasted liquid volume in a sealed container is 20%-25%, resulting in huge social waste and increased operating costs.

[0004] The above shortcomings need to be improved. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a multi-channel fresh beer bottling system.

[0006] The technical solution of this invention is as follows: A multi-channel fresh beer bottling system includes a sealed container for holding the beer, a bottling assembly, and a control center. A storage tank is disposed between the sealed container and the bottling assembly. The sealed container, the storage tank, and the bottling assembly are all connected to a gas supply pipeline. The gas in the gas pipeline propels the wine in the sealed container into the storage tank. After the wine is left to stand in the storage tank, it is filled into bottles by the filling assembly. The control center adjusts the pressure of the sealed container, the storage tank, and the filling assembly by controlling the connection status of each section of the gas pipeline, so that there is a pressure difference between the sealed container, the storage tank, and the filling assembly. Under the action of the pressure difference, the wine flows from the sealed container into the filling assembly after standing in the storage tank. When the wine is standing, the gas pressure in the storage tank is stable.

[0007] In the aforementioned multi-channel fresh beer bottling system, the storage tank is connected to a venting pipe equipped with a venting valve, an inlet pipe equipped with an inlet valve, and an inlet pipe equipped with a beer inlet valve. When the venting valve and the inlet valve are opened, the pressure inside the storage tank decreases, and the beer flows into the storage tank under the push of gas from the gas supply pipe.

[0008] Furthermore, the storage tank has a built-in level gauge, which sends a level signal to the control center. The wine flows from the sealed container into the storage tank under the gas push of the gas pipeline. When the liquid level in the storage tank rises to the upper set height, the control center closes the vent valve, and the wine stops flowing into the storage tank. The wine flows from the storage tank into the filling assembly under the gas push of the air inlet pipe. When the liquid level in the storage tank drops to a lower set height, the control center opens the vent valve, and the wine in the sealed container flows into the storage tank. The wine then stops flowing into the filling assembly.

[0009] Furthermore, the storage tank is equipped with an upper position sensor and a lower position sensor, both of which are connected to the control center. The wine flows from the sealed container into the storage tank under the gas push of the gas pipeline. When the liquid level in the storage tank rises to the sensing range of the upper position sensor, the control center closes the vent valve, and the wine stops flowing into the storage tank. The wine flows from the storage tank into the filling assembly under the gas push of the air inlet pipe. When the liquid level in the storage tank drops to the sensing range of the lower position sensor, the control center opens the vent valve, and the wine in the sealed container flows into the storage tank. The wine then stops flowing into the filling assembly.

[0010] Furthermore, the storage tank is made of a transparent material. Preferably, the storage tank is made of glass.

[0011] The aforementioned multi-channel fresh beer bottling system includes a bottling assembly comprising a bottling pipeline, a bottling head, and multiple vent valves. The bottling pipeline is connected to different sealed containers via multiple different pipelines. A storage tank and a bottling valve are provided between the sealed containers and the bottling pipeline. One end of the bottling head is connected to the bottling pipeline, and the other end of the bottling head is connected to multiple vent valves. The bottling pipeline is connected to the vent valves via the bottling head and a bottling bottle located below the bottling head.

[0012] Furthermore, the control center controls the opening of the exhaust valve and the filling valve, allowing the wine to flow from the storage tank into the filling bottle via the filling head; the control center also controls the closing of the exhaust valve and the filling valve, stopping the flow of the wine into the filling bottle.

[0013] Furthermore, as the wine flows from the storage tank into the bottling bottle, the control center controls the opening states of multiple exhaust valves to form various control combinations. The changes in the control combinations continuously alter the air pressure inside the bottling bottle, and simultaneously, the speed at which the wine flows into the bottling bottle changes with the air pressure inside the bottling bottle.

[0014] Furthermore, a flow meter is installed between the storage tank and the filling pipeline. The flow meter is connected to and sends a flow signal to the control center. The control center has a built-in unit filling volume control index. When the flow signal reaches the unit filling volume, the control center controls the exhaust valve and the filling valve to close.

[0015] Furthermore, a waste liquid tank is provided between the filling head and the exhaust valve, the waste liquid tank is connected to the waste liquid pipeline via a drain valve, and the drain valve is connected to the control center.

[0016] Furthermore, the filling pipeline is connected to the clean water tank via a clean water valve, and a pump body is installed between the clean water valve and the clean water tank. Both the clean water valve and the pump body are connected to the control center.

[0017] Furthermore, the filling pipeline is connected to two gas supply pipelines, one of which is equipped with a large flow valve, and the other is equipped with a small flow valve and a pressure regulating valve.

[0018] The above-mentioned multi-channel fresh beer bottling system is installed in a refrigerator, which has a built-in water-cooled box. Multiple sealed containers are connected to the storage tank via cooling steel pipes installed in the water-cooled box, and the storage tank is placed inside the water-cooled box.

[0019] Furthermore, the inner surface wall of the water-cooled box is provided with a surrounding copper tube, the copper tube contains coolant, and the copper tube is connected to the compressor.

[0020] Furthermore, the cooling steel pipes connecting the different sealed containers are all arranged in a surrounding manner, and multiple cooling steel pipes form a multi-layer structure placed inside the water-cooled box, with a water pump installed at the center of the water-cooled box.

[0021] In the aforementioned multi-channel fresh beer bottling system, the gas supply pipeline is connected to a gas tank and a deaerator, and the gas tank and the deaerator output gas through the gas supply pipeline.

[0022] According to the above-described solution, the beneficial effects of this invention are as follows: a storage tank is set between the filling bottle and the sealed container to temporarily store a portion of the wine before it enters the filling bottle. The storage tank is connected to an inlet and outlet gas pipeline to stabilize the gas pressure inside the storage tank. Under stable pressure, the gas on the surface of the wine in the storage tank redissolves, causing defoaming. At the same time, the inlet and outlet gas pipeline continuously replenishes gas to ensure the taste of the wine. This process can eliminate the foaming phenomenon caused by insufficient pressure. Liquid near the liquid dispensing pipe of the sealed container can also be fully utilized, thereby reducing waste and lowering operating costs.

[0023] 1. Fully Automated Filling Process. The equipment's control center receives sensor signals from various locations, such as air pressure and liquid level signals. The control center controls the connectivity of each pipeline by controlling the valves located at various points, thereby controlling the flow of liquid or gas in different pipelines. The pressure difference generated in the pipelines creates a driving force, causing the liquid or gas to move to the desired location, thus allowing the wine in the sealed container to enter the filling bottle, achieving a fully automated filling effect.

[0024] 2. The storage tanks allow for advance detection of situations such as insufficient liquid in sealed containers. The control center can then urge suppliers to replenish the liquid and provide a certain degree of marketing buffer. Attached Figure Description

[0029] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] It should be noted that when a component is referred to as "fixed," "set," or "connected" to another component, it may be located directly or indirectly on that other component. The terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or position based on the orientation or position shown in the accompanying drawings, and are for ease of description only, and should not be construed as limiting the scope of this technical solution. "More" means two or more, unless otherwise explicitly specified.

[0031] A multi-channel fresh beer bottling system, such as Figure 1 , Figure 2 , Figure 3 As shown, the system includes a sealed container for holding the liquid, a filling assembly, and a control center. A storage tank is installed between the sealed container and the filling assembly. The sealed container, the storage tank, and the filling assembly are all connected to gas supply pipelines. The gas in the gas supply pipelines pushes the liquid in the sealed container into the storage tank. After the liquid settles in the storage tank, it is filled into bottles by the filling assembly. The control center adjusts the pressure of the sealed container, the storage tank, and the filling assembly by controlling the connection status of each section of the gas supply pipeline, so that there is a pressure difference between the sealed container, the storage tank, and the filling assembly. Under the action of the pressure difference, the liquid flows from the sealed container into the filling assembly after settling in the storage tank. The gas pressure in the storage tank is stable when the liquid settles.

[0032] The process of storing wine from its sealed container to its bottling involves passing through an inlet valve, cooling steel pipe, storage tank, outlet valve, flow meter, filling valve, and filling head. All of these processes are completed within food-grade stainless steel piping. The driving force for the flow of wine in the piping is the pressure difference between the containers. This pressure difference originates from the continuous supply of carbon dioxide gas through the gas supply pipe connected to the piping. By adjusting the amount of carbon dioxide gas input, pressure differences are created between the containers, promoting the flow of wine and maintaining a certain level of dissolved carbon dioxide in the wine to ensure its flavor.

[0033] In the equipment, the stored liquor is a liquid provided by the supplier and placed in a sealed container. The liquor contains sufficient gas. When the staff replenishes the liquor, they close the inlet valve of the cooling steel pipe and connect the port of the sealed container to the connecting pipe in the equipment. After the connection is completed, the inlet valve is reconnected to make the inlet pipe open.

[0034] The wine inlet pipeline is connected to the gas supply pipeline. Under the action of continuously entering carbon dioxide, the gas pressure at one end of the wine inlet valve is relatively high, and the wine in the sealed container enters the cooling steel pipe set in the water-cooling box through the wine inlet valve.

[0035] A water-cooled chamber is installed in the freezer. A ring-shaped copper tube is wound around the inner wall of the water-cooled chamber, containing coolant. A compressor is connected to the copper tube, keeping the coolant inside at a low temperature. Simultaneously, the water in the water-cooled chamber near the copper tube is constantly exchanging heat with it, causing the water near the copper tube to freeze into ice, forming a layer of ice of a certain thickness. This maintains the heat exchange effect and keeps the liquid inside the water-cooled chamber at a low temperature. In one embodiment, the ice layer thickness near the copper tube is 7 cm, and the liquid temperature inside the water-cooled chamber is 0-5°C. To maintain the ice layer thickness, an ice layer sensor is installed 7 cm away from the copper tube. The ice layer sensor is connected to the compressor. When the ice layer thickness is less than 7 cm, the compressor is activated to lower the coolant temperature, increase the heat exchange rate, and allow the ice layer to return to a thickness of 7 cm or more.

[0036] In the liquid section of the water-cooled tank, the cooling steel pipes for bottling, located in the middle, are coiled in a ring shape, similar to copper pipes, forming layers of cooling loops. This allows the wine passing through these cooling steel pipes to exchange heat with the liquid in the water-cooled tank, achieving cooling and maintaining the output wine at a low temperature of 7°C. The number of cooling steel pipe layers in the water-cooled tank is the same as the number of different types of wine, ensuring that each type of wine is adequately cooled before dispensing, maintaining sufficient internal gas content and a pleasant taste. A water pump is installed in the middle of the liquid section of the water-cooled tank to agitate the coolant, increasing the heat exchange rate within the tank.

[0037] After being cooled by cooling steel pipes, the liquor enters the storage tank for short-term storage. The storage tank is also housed in a water-cooled box, ensuring the liquor entering the tank maintains the low temperature achieved through the cooling steel pipes. The storage tank is also connected to a gas supply pipeline, with an inlet and a venting pipeline between them. The inlet pipeline has an inlet valve, and the venting pipeline has a venting valve. Both pipelines connect to the storage tank via a shared connecting pipe. A pressure sensor is installed in the venting pipeline, which is connected to the equipment's control center and sends a corresponding pressure signal to it. The control center controls the opening degree of the inlet and venting valves. The pressure signal from the pressure sensor triggers the control, causing it to adjust the opening degree of the inlet and venting valves, ensuring the gas pressure inside the storage tank is lower than the pressure in the liquor supply pipeline, allowing the liquor to flow into the storage tank driven by the pressure difference.

[0038] In one embodiment, the storage tank is a transparent glass jar, with a level gauge inside and two pairs of infrared beam detectors on the outside. Both the level gauge and the infrared beam detectors are used to sense the liquid level inside the storage tank and are connected to the control center of the equipment. The level gauge and the infrared beam detectors send liquid level signals to the control center, causing the control center to control the operation of the air inlet valve and the air outlet valve, maintaining a certain volume of liquid in the storage tank. When the control center opens the air outlet valve, the air pressure inside the storage tank is lower than the air pressure in the inlet pipe. Driven by the input carbon dioxide gas, the liquid flows into the storage tank, causing the liquid level to rise until it touches the upper infrared beam detector. The upper infrared beam detector and the level gauge send liquid level signals to the control center. Simultaneously, a pressure sensor located in the air outlet pipe also sends a pressure signal to the control center. Based on the received liquid level and pressure signals, the control center adjusts the opening degree of the air outlet valve, gradually increasing the air pressure inside the storage tank until it matches the air pressure in the inlet pipe, thus stopping the flow of liquid in the sealed container.

[0039] Preferably, the air intake pipe is equipped with a one-way valve with a screen to prevent the wine and gas in the storage tank from flowing back.

[0040] The lower part of the storage tank is connected to a wine outlet pipeline, which is equipped with a wine outlet valve, a flow meter, and a filling valve in sequence. The wine outlet valve controls the connection status of the wine outlet pipeline, or in other words, the port connecting the storage tank and the wine outlet pipeline. The other end of the wine outlet pipeline is equipped with a flow meter and a filling valve. After the customer completes payment, the filling bottle is in place, and the equipment's control center activates the filling valve of the pipeline corresponding to the wine type, while simultaneously opening the wine outlet valve at the wine outlet pipeline port. This allows the wine stored in the storage tank to flow out through the wine outlet valve, flow meter, and filling valve, and then into the filling bottle along the filling head of the filling pipeline.

[0041] Preferably, the level gauge is a stainless steel float level gauge.

[0042] During filling, the bottle is positioned so that it becomes part of the filling pipeline, with one end of the filling head connected to the other end of the filling head via the bottle.

[0043] One end of the filling head is connected to a water pipeline, an airflow pipeline, and a wine outlet pipeline via filling pipelines. The water pipeline connects to a water tank containing water, and a diaphragm pump draws water from the tank into the water pipeline. A water valve controls the connection between the water pipeline and the filling pipeline. The airflow pipeline is divided into a large airflow pipeline and a small airflow pipeline. The large airflow pipeline connects to the gas supply pipeline to provide the driving force for wine filling. The small airflow pipeline connects to the gas supply pipeline via a pressure regulating valve, thereby reducing the pressure within the small airflow pipeline, creating a smaller airflow pipeline with lower pressure than the larger one, which provides the driving force for water to flow into the filling pipeline. Both the large and small airflow pipelines are equipped with large and small airflow valves at their connections to the filling pipeline to control the airflow status. One end of the filling head is connected to the dispensing lines of various types of alcoholic beverages. That is, alcoholic beverages that were originally in different lines all enter the filling head and flow into the filling bottle through the same filling line. Each dispensing line and filling line is equipped with a flow meter and a filling valve at the connection port. The flow meter is used to count the amount of alcohol dispensed from each line, and the filling valve is the final control valve for filling.

[0044] The other end of the filling head is connected to a waste liquid tank, which is connected to multiple vent valves. A waste liquid pipeline is connected to the bottom of the waste liquid tank, and a drain valve is installed on the waste liquid pipeline. The vent valves connect to the filling bottle through the waste liquid tank. Therefore, when the vent valves are open, the gas in the waste liquid tank and the filling bottle decreases, and the gas pressure drops. At this time, if the large airflow valve at one end of the filling head and the filling valve of any wine outlet pipeline are opened, the wine from that outlet pipeline will flow from the storage tank into the filling bottle. Similarly, if the clean water valve and the small airflow valve are opened in this state, clean water from the clean water tank can also flow along the filling pipeline into the rinsing cup.

[0045] The waste liquid tank is connected to a pressure sensor, which senses the pressure inside the tank. This pressure is equivalent to the pressure inside the filling bottles connected to the waste liquid tank. The pressure inside the filling bottles is controlled by multiple vent valves connected to them. Therefore, by changing the state of these vent valves, the pressure inside the filling bottles can be altered, changing the pressure difference between the bottles and the filling pipeline. This changes the flow rate of the liquor into the bottles, ultimately reducing foaming during filling, preventing spillage, and improving the taste. Different types of liquor, such as their carbonated content, affect this foam-reducing effect. Therefore, the combination of vent valve states varies depending on the type of liquor and the filling time. By using different combinations of vent valves, the desired foam-reduction effect can be achieved.

[0046] During the filling process, the control center connects to and controls the water valve of the water pipeline, the large airflow valve of the large airflow pipeline, the small airflow valve of the small airflow pipeline, the filling valves of each wine outlet pipeline, the drain valve of the waste liquid pipeline, and multiple vent valves connected to the waste liquid tank. After the customer completes payment, the control center confirms that the bottle is ready to be filled under the filling head and that all pre-filling actions have been completed by sensing signals sent by sensors. It then opens the vent valve connected to the waste liquid tank and the wine outlet valve and filling valve of the corresponding wine outlet pipeline, while simultaneously opening the large airflow valve. In this way, the gas inside the bottle is discharged through the vent valve along the pipeline, the pressure inside the bottle decreases, and the gas flowing through the large airflow valve carries the wine in the wine outlet pipeline into the bottle.

[0047] During this process, the control center has two filling methods, and the triggering mechanisms for the two filling methods are shown above. The difference lies in the filling stop mechanism.

[0048] One type of filling method is quantitative filling, where the filling volume is the storage capacity of the storage tank. The filling stop signal is triggered when the liquid level in the storage tank drops to a set level. Specifically, before filling, the control center controls the air inlet valve and the air outlet valve to store a fixed amount of liquor in the storage tank, causing the liquid level in the storage tank to rise to the set level. This level is detected by a level gauge and an upper infrared beam sensor. At this point, the volume of liquor in the storage tank between the upper and lower infrared beam sensors is equivalent to the standard filling volume of a single bottle. When the filling process begins, the liquor inlet valve in the storage tank is closed, the air outlet valve is closed, and the air inlet valve is open, pushing the liquor in the storage tank into the bottle. The liquid level in the storage tank drops. When the liquid level in the storage tank is within the sensing range of the lower infrared beam sensor, the lower infrared beam sensor sends a stop signal to the control center. The control center then closes the air outlet valve, the filling valve, and the dispensing valve, stopping the filling process. This filling method ensures that the amount of wine flowing into the bottle each time is equal, and that it is always the volume between the upper and lower infrared beam detectors on the storage tank. Similarly, this control method can also be implemented using a level gauge. The level gauge sends a real-time level signal to the control center. When the liquid level in the storage tank drops to a set height, the control center determines to stop filling based on the received level signal. Using a level gauge for filling increases the storage capacity of the storage tank.

[0049] Another filling method is equal-volume filling, where the filling volume is set by the control center. The trigger signal to stop filling is the count of the flow meter installed in the dispensing pipeline. Specifically, when the filling process begins, the inlet valve in the storage tank opens, the vent valve closes, and the air inlet valve opens. The liquid in the storage tank flows into the filling bottle through the flow meter and filling valve. The flow meter measures the liquid flowing through and sends the measurement value to the control center in real time. When the control center determines that the measurement value has reached the set value, it closes the vent valve, filling valve, and dispensing valve, stopping the filling process. This filling method fills the same volume each time, but because it relies on the flow meter for counting, some liquid containing bubbles will still be counted when it flows in, which may ultimately lead to an unqualified filling volume in the bottle, causing filling errors.

[0050] At the end of filling, the bottles containing the liquor are removed, and the cleaning cup is moved to the bottle position, positioned below the filling head. At this time, the water valve opens, and the diaphragm pump starts, drawing water from the water tank into the filling pipeline and allowing it to flow into the cleaning cup. The cleaning cup is connected to a waste liquid tank, and a small water pump moves the liquid in the cleaning cup to the waste liquid tank, completing the cleaning of the filling pipeline. Cleaning the filling pipeline serves two purposes: firstly, it cleans pipelines that have not been used for a long time, ensuring the hygiene of the liquor flowing into the pipeline; secondly, when continuously filling different types of liquor using the same filling pipeline, cleaning the pipeline before each filling is necessary to prevent mixing of liquors and affecting the product taste. Of course, the water valve, diaphragm pump, and water pump are all controlled collaboratively by a central control unit. Therefore, when the control unit receives multiple consecutive filling tasks for the same type of liquor, it automatically identifies the task, eliminating the need for cleaning the filling pipeline before each filling.

[0051] In one embodiment, the gas pipeline is connected to a carbon dioxide tank and an oxygen deaerator, respectively. When the staff changes the sealed container of the wine, they also change the carbon dioxide tank. At the same time, the oxygen deaerator can also generate carbon dioxide using air as raw material.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
