Description

Technical Field

[0001] The present application relates to the technical field of beer production, and in particular to a beer bottle internal pressure testing device and a bottle internal pressure detection method. Background Art

[0002] In the beer production process, in order to ensure the safety of beer drinking, beer is generally pasteurized after canning to kill the microorganisms inside. Since beer is a gas beverage mainly rich in carbon dioxide, during the sterilization process, as the temperature rises, carbon dioxide gas overflows from the beer, Brownian motion intensifies, and the pressure in the container rises sharply; when the temperature drops, part of the carbon dioxide dissolves in the beer, and the Brownian motion slows down, the pressure in the container drops, and the changes in temperature and pressure put forward new requirements for the quality of packaging containers. In order to avoid the damage, leakage, explosion, etc. of the packaging container during the beer sterilization process, which affects the quality of the beer or causes safety problems, it is necessary to study the relationship between the changes in pressure and temperature during this process.

[0003] The relationship between pressure and temperature during beer sterilization is an important indicator for evaluating the production adaptability of packaging containers. It not only affects the quality of the beer, but also has an early warning effect on potential production safety.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0049] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

[0052] See also Figure 1 As shown, Figure 1 The schematic diagram of the structure of the beer bottle internal pressure test device provided in the embodiment of the present application includes a beer bottle internal pressure test device, including: a beer bottle simulation tank 1, a first pipe 2, a second pipe 5 and a third pipe 9 connected to the beer bottle simulation tank 1. A pressure sensor 8 is provided at the end of the third pipe 9, and a temperature sensor 12 for detecting the temperature of the beer liquid inside the beer bottle simulation tank 1 is provided on the beer bottle simulation tank 1.

[0053] The interior of the wine bottle simulation tank 1 is used to contain wine. The wine bottle simulation tank 1 simulates the bottle shape of a conventional beer bottle, thereby equivalently simulating the pressure inside an actual wine bottle and the state of the wine liquid it carries.

[0054] The first pipe 2 is connected from the bottom of the wine bottle simulation tank 1 to the inside thereof, and the other end is open to the outside. A first flow control element 3 is provided on the first pipe 2, and the first flow control element 3 is used to control the flow and closure in the first pipe 2. In the first pipe 2, a first transition space 4 is formed between the first flow control element 3 and the wine bottle simulation tank 1. The first transition space 4 is equivalent to the additional transportation flow space generated by the first pipe 2 on the wine bottle simulation tank 1, and the first transition space 4 can also accommodate wine and gas. Therefore, when calculating the pressure and volume in the wine bottle simulation tank 1, it is inevitable to add the data in the space together for calculation. The first transition space 4 is set between the first flow control element 3 and the wine bottle simulation tank 1 in order to accurately limit the scope of the first transition space 4. In actual use, after the first flow control element 3 closes the first pipe 2, the part located inside the first pipe 2 and outside the first transition space 4 will not be included in the calculation of the internal volume of the wine bottle simulation tank 1.

[0055] The second pipe 5 is connected from the top of the wine bottle simulation tank 1 to the interior thereof, and the other end of the second pipe 5 is connected to the outside of the wine bottle simulation tank 1 .

[0056] Similarly, a second flow control element 6 is provided on the second pipe 5, and the second flow control element 6 is used to control the flow and closure in the second pipe 5. A second transition space 7 is formed between the second flow control element 6 and the wine bottle simulation tank 1. The second transition space 7 is equivalent to the additional transportation flow space generated by the second pipe 5 on the wine bottle simulation tank 1, and the second transition space 7 can also accommodate wine and gas. Therefore, when calculating the pressure and volume in the wine bottle simulation tank 1, it is inevitable to add the data in this space together for calculation. The second transition space 7 is set between the second flow control element 6 and the wine bottle simulation tank 1 in order to accurately limit the scope of the second transition space 7. In actual use, after the second flow control element 6 closes the second pipe 5, the part located inside the second pipe 5 and outside the second transition space 7 will not be included in the calculation of the internal volume of the wine bottle simulation tank 1.

[0057] The pressure sensor 8 is connected to the interior of the wine bottle simulation tank 1 through the third pipe 9, and the pressure sensor 8 is used to detect the pressure inside the wine bottle simulation tank 1 in real time. The temperature sensor 12 is also connected to the interior of the wine bottle simulation tank 1 but does not occupy the internal space and is not included in the internal pressure calculation.

[0058] Similarly, a third flow control element 10 is provided on the third pipe 9, and the third flow control element 10 is used to control the flow and closure in the third pipe 9. When the third pipe 9 is closed, the pressure sensor 8 cannot detect the internal pressure of the wine bottle simulation tank 1.

[0059] A third transition space 11 is formed between the third flow control element 10 and the wine bottle simulation tank 1. The third transition space 11 can also generate additional transport circulation space to accommodate wine and gas. Therefore, when calculating the pressure and volume in the wine bottle simulation tank 1, it is inevitable to add the data in this space together for calculation. The third transition space 11 is set between the third flow control element 10 and the wine bottle simulation tank 1 in order to accurately limit the scope of the third transition space 11. In actual use, after the third flow control element 10 closes the third pipe 9, the part located inside the third pipe 9 and outside the third transition space 11 will not be included in the calculation of the internal volume of the wine bottle simulation tank 1. In theory, there should be no additional space between the third flow control element 10 and the pressure sensor 8 inside the third pipe 9, so as to avoid affecting the internal calculation accuracy. However, if there is additional space, the deviation value caused by it can also be calculated in the actual calculation process.

[0060] Among them, the third flow control element 10 can limit the wine to be connected with the pressure sensor 8 after completing various preliminary preparations in the wine bottle simulation tank 1, thereby reducing the soaking time of the wine in the pressure sensor 8 and reducing the degree of wear of the pressure sensor 8 during daily use.

[0061] The temperature sensor 12 is connected to the interior of the wine bottle simulation tank 1 and is used to detect the temperature of the wine inside the wine bottle simulation tank 1. During the process of the temperature sensor 12 being connected to the interior of the wine bottle simulation tank 1, no additional space capable of carrying liquid and gas is generated.

[0062] The beer bottle internal pressure testing device also includes a temperature control system, which needs to be arranged on the outside of the wine bottle simulation tank 1 to adjust the temperature of the wine inside the wine bottle simulation tank 1. The first transition space 4, the second transition space 7 and the third transition space 11 are all used to carry the wine and gas. The three transition spaces are provided to reserve transportation space for the wine and gas to be poured into the wine bottle simulation tank 1. The internal space of the wine bottle simulation tank 1 plus the first transition space 4, the second transition space 7 and the third transition space 11 are used to carry liquid and gas. For the convenience of description, the combined space is referred to as a cavity in this article, and the cavity is used to refer to the overall space hereinafter.

[0063] In one embodiment of the present application, the third flow control element 10 is closed, the first flow control element 3 and the second flow control element 6 are opened, and the wine is slowly pumped into the first flow control element 3 to fill the cavity from bottom to top until the wine flows out of the second flow control element 6 and the pumping of the wine is stopped.

[0064] Then, high-purity CO2 (carbon dioxide) gas is connected to the second flow control element 6, and a liquid measuring container is placed at the first flow control element 3. CO2 gas is slowly introduced until the volume of the wine flowing out of the first flow control element 3 is the discharge volume of the wine bottle of the same bottle type, and then the ventilation is stopped; the first flow control element 3 is closed, and the third flow control element 10 is opened, so that the pressure sensor 8 detects the pressure inside the cavity of the above-mentioned wine bottle simulation tank 1 in real time, and the ventilation continues slowly until the pressure inside the cavity reaches the filling pressure of the wine bottle of the same bottle type, and then the ventilation is stopped and the second flow control element 6 is closed. Subsequently, the temperature of the wine inside the wine bottle simulation tank 1 is regulated by the temperature control system, and the pressure value in the cavity formed by the wine bottle simulation tank 1 at each constant temperature is recorded. This equipment has the advantages of real-time monitoring, accurate measurement, simple operation, etc., and has strong versatility and is suitable for promotion.

[0065] In one embodiment of the present application, the first flow control element 3, the second flow control element 6 and the third flow control element 10 are all configured as valve elements. The valve elements are used to realize the opening and closing control of the inside of the pipeline, and the boundaries of the first transition space 4, the second transition space 7 and the third transition space 11 can be clearly separated after the valve elements close the pipeline.

[0066] In one embodiment of the present application, the temperature control system is set as a thermostatic box, and the wine bottle simulation tank 1 is set in the thermostatic box. By adjusting the temperature of the thermostatic box, the wine bottle simulation tank 1 is placed in a constant temperature environment, so that the wine inside changes the pressure in the simulated bottle with the change of temperature. By detecting the change of the pressure in the simulated bottle under each constant temperature state, the relationship curve between the internal pressure and temperature change of the actual beer bottle is equivalently calculated.

[0067] It can be foreseen that the temperature control system can be set to any constant temperature control device equivalent to a constant temperature box, such as a water bath, etc., as long as it can meet the above-mentioned technical effect of stably controlling the temperature of the wine bottle simulation tank 1, and this article will not elaborate on it.

[0068] Reference Manual Attached Figure 2 , Figure 2 The method flow chart of the method for detecting the pressure inside a bottle provided in the embodiment of the present application includes a method for detecting the pressure inside a bottle, which is applicable to the above-mentioned beer bottle pressure testing device, and the method includes:

[0069] S1, confirm the wine bottle of the bottle type corresponding to the above-mentioned wine bottle simulation tank 1, obtain the filling pressure of the wine bottle of the corresponding bottle type after filling with wine as the actual filling pressure P0, and obtain the nominal capacity V and full mouth capacity V0 of the wine bottle of the corresponding bottle type.

[0070] Specifically, the wine bottle corresponding to the bottle type of the wine bottle simulation tank 1 mentioned above means that the wine bottle simulation tank 1 of the present application is essentially set in the shape of a conventional applicable wine bottle, so that the simulated environment in the wine bottle simulation tank 1 can be consistent with the state in the actual wine bottle. Further, the size, bottle type, material, weight and other data of the wine bottle simulation tank 1 should be consistent with the specification data of the wine bottle to be tested. This article is to test the relationship between temperature and pressure in the wine bottle, so only the internal pressure and volume related content are explained. It is foreseeable that, ideally, all production data of the wine bottle simulation tank 1 should be set in accordance with the actual wine bottle.

[0071] On the other hand, a small amount of carbon dioxide will also be dissolved in the wine. The actual filling pressure P0 is formed by the carbon dioxide gas in the wine bottle of the corresponding bottle type. A part of the carbon dioxide gas will be dissolved in the wine until the carbon dioxide dissolved in the wine is reached, and the remaining gas forms the actual filling pressure P0. Different wines can fully dissolve different amounts of carbon dioxide under different conditions. Therefore, the wine loaded in the bottle can be preset, and the carbon dioxide content of the wine in the bottle can be tested to ensure that the carbon dioxide content in the wine is at a saturated fixed value each time it is tested, so as not to affect the test results.

[0072] S2, calculating the effective volume rate R of the wine bottle of the corresponding bottle type according to the above nominal capacity V and the above full mouth capacity V0.

[0073] Specifically, the effective volume rate R of a wine bottle refers to the proportion of the actually available storage space or fluid flow space in the entire container volume. According to different bottle types and different bottling standards, the effective volume rate R of each wine bottle can be calculated separately.

[0074] S3 , obtaining a first volume V1 of the first transition space 4 , a second volume V2 of the second transition space 7 , and a third volume V3 of the third transition space 11 .

[0075] Specifically, the first transition space 4 , the second transition space 7 and the third transition space 11 can all be used for the circulation of wine, and the three are connected to the internal volume of the wine bottle simulation tank 1 .

[0076] S4, calculating and obtaining the actual filling volume V4 and the discharge volume V5 according to the effective volume rate R, the first volume V1, the second volume V2 and the third volume V3.

[0077] Specifically, the actual filling volume V4 and the discharge volume V5 are calculated for the transition space of the three pipes and the internal volume of the wine bottle simulation tank 1 as a whole.

[0078] S5, close the third flow control element 10, open the first flow control element 3 and the second flow control element 6, pump the wine from the first flow control element 3 into the wine bottle simulation tank 1, and stop pumping the wine after it overflows from the second flow control element 6.

[0079] Specifically, this operation can evacuate the interior of the cavity while injecting the wine, thereby avoiding the presence of gas in the cavity.

[0080] S6, placing a liquid measuring container at the opening of the first flow control element 3, and introducing carbon dioxide gas into the wine bottle simulation tank 1 from the second flow control element 6, so that the wine is discharged from the first flow control element 3 into the liquid measuring container, and the introduction of carbon dioxide gas is stopped after the volume of the wine in the liquid measuring container is equal to the discharged volume V5.

[0081] Specifically, the carbon dioxide gas is slowly introduced from the second flow control element 6 to control the carbon dioxide gas to always maintain high purity. The wine is discharged from the first flow control element 3 to the liquid container by the carbon dioxide gas, and the amount of wine retained in the cavity can be equivalent to the amount of wine in a bottle of the same bottle type.

[0082] S7, close the above-mentioned first flow control element 3, open the above-mentioned third flow control element 10, and continue to introduce carbon dioxide gas until the above-mentioned pressure sensor 8 detects that the simulated filling pressure P inside the wine bottle simulation tank 1 is equal to the above-mentioned actual filling pressure P0, then stop introducing carbon dioxide gas and close the second flow control element 6.

[0083] Specifically, the interior of the wine bottle simulation tank 1 is continuously pressurized in the above manner until the simulated filling pressure P is equal to the actual filling pressure P0 in a wine bottle of the same type, thereby simulating the scene inside the actual bottle.

[0084] S8, adjusting the temperature of the wine in the wine bottle simulation tank 1 by the temperature control system, and detecting the simulated filling pressure P data inside the wine bottle simulation tank 1 at various temperatures by the temperature sensor 12.

[0085] In one embodiment of the present application, in step S5, the third flow control element 10 is closed, the first flow control element 3 and the second flow control element 6 are opened, and the wine is pumped from the first flow control element 3 into the wine bottle simulation tank 1 until the wine overflows from the second flow control element 6 and the pumping is stopped, and the process also includes: precooling the wine to be filled in a low temperature environment for at least four hours; the temperature range of the low temperature environment is between 2 degrees Celsius and 6 degrees Celsius.

[0086] Specifically, the pre-cooling operation of the wine can control the variables during the detection, and the interior of the wine after the pre-cooling operation is more stable, avoiding the outflow of carbon dioxide gas from the high-temperature wine.

[0087] In one embodiment of the present application, with respect to step S2, the effective volume rate R of the wine bottle of the corresponding bottle type is calculated according to the nominal capacity V and the full mouth capacity V0, including:

[0088] The above-mentioned effective volume ratio R is equal to the percentage of the above-mentioned nominal capacity V to the above-mentioned full mouth capacity V0.

[0089] That is, R=V / V0*100%.

[0090] In one embodiment of the present application, for step S4, the actual filling volume V4 and the discharge volume V5 are calculated according to the effective volume rate R, the first volume V1, the second volume V2 and the third volume V3, including:

[0091] The actual filling volume V4 is equal to the full mouth capacity V0 plus the sum of the first volume V1, the second volume V2 and the third volume V3 multiplied by the effective volume rate R.

[0092] That is, V4=V0+V1+V2+V3.

[0093] In one embodiment of the present application, for step S4, the actual filling volume V4 and the discharge volume V5 are calculated according to the effective volume rate R, the first volume V1, the second volume V2 and the third volume V3, including:

[0094] The above-mentioned discharge volume V5 is equal to the above-mentioned full mouth capacity V0 plus the sum of the above-mentioned first volume V1, the above-mentioned second volume V2 and the above-mentioned third volume V3 minus the above-mentioned actual filling volume V4.

[0095] That is, V5=V0+V1+V2+V3-V4.

[0096] In one embodiment of the present application, for step S6, a liquid measuring container is placed at the first flow control element 3, and carbon dioxide gas is introduced into the wine bottle simulation tank 1 from the second flow control element 6, so that the wine is discharged from the first flow control element 3 into the liquid measuring container, and the introduction of carbon dioxide gas is stopped after the volume of the wine in the liquid measuring container is equal to the discharge volume V5, including: the liquid measuring container is set as a measuring cylinder. The measuring cylinder is convenient for checking the volume of the discharged liquid in real time. It is foreseeable that a liquid measuring container with the same effect as the measuring cylinder is also applicable, which will not be elaborated in this article.

[0097] In one embodiment of the present application, with respect to step S8, the temperature of the wine in the wine bottle simulation tank 1 is adjusted by the temperature adjustment system, and the internal pressure data of the wine bottle simulation tank 1 at various temperatures is detected by the temperature sensor 12, including:

[0098] The temperature control system adjusts the wine bottle simulation tank 1 to various constant temperature states, records the internal pressure data of the wine bottle simulation tank 1 under various constant temperature states, and draws a temperature-pressure relationship curve.

[0099] In one embodiment of the present application, a device for testing the internal pressure of beer bottles filled according to the above method is set to different temperatures as needed. After the temperature of the beer is stabilized, the corresponding pressure is read and a temperature-pressure curve is plotted based on the pressures at different temperatures.

[0100] The following are the data measured by the beer bottle internal pressure test device of the present application after taking 500 milliliters (ml) of each of the two bottled beers. Specifically,

[0101] The experimental data chart of the first bottled beer can be referenced Figures 3 to 5 :

[0102] Figure 3 The table shows various data of taking 500 ml of the first bottled beer into the bottle provided in the embodiment of the present application. It shows the nominal capacity V, full capacity V0, actual filling pressure P0, effective volume rate R, first volume V1, second volume V2, third volume V3, actual filling volume V4 and discharge volume V5 of the first bottled beer (equivalent to the first bottle simulation tank 1) after 500 ml of beer is placed.

[0103] At the same time, the first type of wine added to the wine bottle is selected, and the carbon dioxide content of the first type of wine is determined to be 2.05 g / L (grams per liter), accounting for 0.205% of the total liquid. At this time, the carbon dioxide content of the wine in the embodiment is a value that varies according to the type of wine, and is only used here as data support to improve the data of the embodiment. It is foreseeable that when different amounts of carbon dioxide are dissolved in the wine, the amount of carbon dioxide injected when high-concentration carbon dioxide is subsequently introduced for emptying is different. Further, the step of introducing high-concentration carbon dioxide to simulate the pressurization in the tank may also be affected. Therefore, the content of the wine is quantitatively obtained in advance to avoid parameter changes. Here, only the data when the carbon dioxide content of the wine is 2.05 g / L (grams per liter) and accounts for 0.205% of the total liquid are displayed.

[0104] Figure 4 The pressure data display table of the first bottled beer at different temperatures provided by the embodiment of the present application shows the corresponding data of the temperature in the first bottled beer and the simulated filling pressure P at different temperatures.

[0106] The experimental data chart of the second bottled beer can be referenced Figures 6 to 8 :

[0107] Figure 6 The table shows various data of taking 500 ml of the second bottled beer into the bottle provided in the embodiment of the present application. It shows the nominal capacity V, full capacity V0, actual filling pressure P0, effective volume rate R, first volume V1, second volume V2, third volume V3, actual filling volume V4 and discharge volume V5 of the second bottled beer (equivalent to the second bottle simulation tank 1) after 500 ml of beer is placed.

[0108] At the same time, the wine added to the wine bottle is selected, and the carbon dioxide content of the wine is determined to be 2.05g / L (grams per liter), accounting for 0.205% of the total liquid. At the same time, the second wine added to the wine bottle is selected, and the carbon dioxide content of the second wine is determined to be 2.05% of the total amount. At this time, the carbon dioxide content of the wine in the embodiment is a value that varies according to the type of wine, and is only used here as data support to improve the data of the embodiment. It is foreseeable that when the wine dissolves different amounts of carbon dioxide, the amount of carbon dioxide injected when high-concentration carbon dioxide is subsequently introduced for emptying is different. Further, the step of introducing high-concentration carbon dioxide to simulate the pressurization in the tank may also be affected. Therefore, the content of the wine is quantitatively obtained in advance to avoid parameter changes. Here, only the data when the carbon dioxide content of the wine is 2.05g / L (grams per liter) and accounts for 0.205% of the total liquid are displayed.

[0111] The above-mentioned temperature and pressure test experiment is essentially to simulate the performance state of bottled beer during the heating and sterilization process. The above-mentioned two embodiments are used to demonstrate that the beer bottle internal pressure testing device of the present application can accurately reflect the change of the pressure inside the bottle with the temperature during the heating process of beer. Through the accumulation of data, the safety indicators of the packaging container can also be specified according to this change to ensure the quality of the beer and the safety of production.

[0112] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
