DETAILED DESCRIPTION

[0025] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] This embodiment provides a device for detecting the alcohol content in an alcohol mixture, such as Figure 1 and Figure 2 As shown, it includes a pipeline mixer 1, a wine container 2, a mass flow meter 3, a first regulating valve 4 and a digital processor (not shown in the figure).

[0027] The wine holding part 2 is used for containing various raw materials for manufacturing the alcohol-liquid mixture. The wine holding part 2 in this embodiment includes a first container 21 and a second container 22. The first container 21 and the second container 22 are arranged in parallel. Pure water is arranged in the first container 21, and alcohol is arranged in the second container 22. Both are connected to the inlet of the pipeline mixer 1, so that the pure water in the first container 21 and the alcohol in the second container 22 can be mixed into an alcohol-liquid mixture in the pipeline mixer 1, and the concentration of alcohol in the alcohol-liquid mixture can be controlled by controlling the flow rate of pure water and alcohol.

[0028] The inlet and the outlet of the mass flow meter 3 are connected to the outlet of the pipeline mixer 1 and the third container 5 respectively. The mass flow meter 3 is used to detect the density of the fluid in the pipeline mixer 1 .

[0029] The first regulating valve 4 is arranged between the mass flow meter 3 and the third container 5 . When the first regulating valve 4 is closed, the mass flow meter 3 is not connected to the third container 5 . When the first regulating valve 4 is opened, the mass flow meter 3 is connected to the third container 5 .

[0030] In this embodiment, the alcohol content is analyzed with density and temperature, and the concentration, temperature and density are in a certain relationship, specifically:

[0031] The relationship between alcohol content, density and temperature can be described in points:

[0032] 1. Relationship between alcohol content and density:

[0033] At a certain temperature, the concentration of alcohol is positively correlated with its density. This means that the higher the concentration, the greater the density. For example, the comparison table provided in Reference 1 shows that as the mass percentage of ethanol increases, its density (g / cm 3 ) also increases accordingly.

[0034] 2. Relationship between alcohol density and temperature:

[0035] The density of ethanol is inversely proportional to temperature. That is, as the temperature rises, the density of ethanol decreases. This is because the increase in temperature weakens the interaction between ethanol molecules and increases the space between molecules, resulting in a decrease in density. For example, at 45°C, the density of ethanol is 0.824 g / cm 3 , lower than the density at room temperature.

[0036] 3. The relationship between alcohol content and temperature:

[0037] For pure alcohol, its concentration will not change due to temperature changes. However, for alcohol solutions containing water (such as liquor), the water will evaporate when heated, which may lead to a relative increase in alcohol content. This is because after the water evaporates, the ethanol concentration in the solution increases relatively.

[0038] According to Appendix A of "Analysis Method of Liquor GB / T 10345-2007", the relative density and alcohol content comparison table of alcohol solution at different temperatures can be obtained. According to Appendix A and the required alcohol content, the preset range of density of alcohol mixture can be obtained. At the same time, the range of alcohol content can also be obtained through the preset range. As an example, the method of obtaining is as follows:

[0039] Based on Appendix A, the mathematical relationship between temperature, alcohol content and density can be obtained through fitting and other methods. Based on the mathematical relationship and the required alcohol content, a preset range can be obtained. At the same time, the required alcohol content can also be derived based on the required preset range.

[0040] Therefore, by measuring the density, solution and temperature of the alcohol liquid mixture, the alcohol content can be calculated. Therefore, when it is detected that the density of the alcohol liquid mixture is within the preset range, it means that the alcohol content meets the requirements. If it is not within the preset range, it means that the alcohol content does not meet the requirements and should be discarded.

[0041] Therefore, in this embodiment, the digital processor electrically connected to the first regulating valve 4 is electrically connected to the mass flow meter and the first regulating valve, and is used to detect whether the density of the alcohol liquid mixture in the pipeline mixer is within a preset range. When the density is within the preset range, the first regulating valve 4 is controlled to open, and the outlet of the mass flow meter 3 is connected to the third container 5, and the alcohol liquid mixture that meets the requirements will flow into the third container 5 to store the alcohol liquid mixture that meets the requirements. Otherwise, the first regulating valve 4 is controlled to be closed, so that the mass flow meter 3 is not connected to the third container 5, and the alcohol liquid mixture that does not meet the requirements cannot enter the third container 5.

[0042] In at least one embodiment, the digital processor is used to process the digital signal, in which a preset range is set, and when the density measured by the mass flow meter 3 is collected, if the density is within the preset range, a high level signal is issued, and after the first regulating valve 4 receives the high level signal, the state is set to open. Otherwise, a low level signal is issued, and after the first regulating valve 4 receives the low level signal, the state is set to closed.

[0043] In this embodiment, a first ball valve 6 is provided between the mass flow meter 3 and the first container 21. The first ball valve 6 is electrically connected to the digital processor. When the density is within a preset range, the first ball valve 6 is controlled to be closed, and the mass flow meter 3 is not connected to the first container 21, so that the alcohol liquid mixture that meets the demand will not flow into the third container 5. Otherwise, the first ball valve is controlled to be opened, so that the mass flow meter 3 is connected to the first container 5, and the alcohol liquid mixture that meets the demand flows into the first container 21, thereby avoiding waste of alcohol.

[0044] In this embodiment, after the first ball valve 6 receives a high-level signal, the state is set to be closed, and after receiving a low-level signal, the state is set to be open.

[0045] In this embodiment, a second regulating valve 7 is provided between the first container 21 and the pipeline mixer 1, and a third regulating valve 10 is provided between the second container 22 and the pipeline mixer 1. By adjusting the opening of the second regulating valve 7 and the third regulating valve 10, the flow rates of the two are controlled, and then by controlling the opening time, the alcohol and pure water are gathered in the pipeline mixer 1 to form an alcohol liquid mixture of the desired concentration.

[0046] In this embodiment, a second ball valve 8 and a third ball valve 9 are provided between the second regulating valve 7 and the first container 21 to control the opening and closing of the first container 21 .

[0047] In this embodiment, a feed pump 11 is provided between the third regulating valve 10 and the second container 22, which is used to pump alcohol into the pipeline mixer 1. The liquid in the first container 21 can flow into the pipeline mixer 1 by gravity, so there is no need to provide a pump body. A fourth ball valve 12 is provided between the feed pump 11 and the third regulating valve 10. When the fourth ball valve 12 is opened, it is used to control the opening and closing of the pipeline between the feed pump 11 and the second regulating valve 10.

[0048] The process of implementing wine dispensing based on the device proposed in this embodiment is as follows:

[0049] 1. Set process control parameters and start;

[0050] 2. Set the process frequency of the feed pump 11 as required and fully open the third regulating valve 10;

[0051] 3. Then open the second regulating valve 7, and the alcohol and pure water are mixed through the pipeline mixer 1 through the above valve;

[0052] 4. The density of the mixed liquid is measured by the mass flow meter 3. If it is not within the preset range, the first regulating valve 4 is automatically closed, the first ball valve 6 is opened, and the liquid is sent into the first container 21. If it is within the preset range, the first regulating valve is opened, and the second regulating valve 7 is used to fine-tune the concentration of the mixed liquid as required.

[0053] The above description is only an embodiment of the present application and is not intended to limit the protection scope of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
