Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide determination technology for carbonated orange juice beverages, and in particular to a distillation system for carbon dioxide determination of carbonated orange juice beverages. Background Technology

[0002] Carbonated orange juice contains carbon dioxide, which, in moderation, provides a stimulating sensation and rich foam, enhancing the drinking experience. However, excessive carbon dioxide content results in overly abundant and intense bubbles, leading to an overly irritating taste, even a burning sensation in the throat, and masking the beverage's natural flavor. Furthermore, consuming beverages with excessive carbon dioxide releases a large amount of carbon dioxide into the stomach, potentially causing bloating, stomach pain, and other discomfort. To facilitate the determination of carbon dioxide content in carbonated orange juice, our company's technical personnel have developed a carbon dioxide determination distillation system for carbonated orange juice, as described in this application. Utility Model Content

[0003] The purpose of this invention is to provide a distillation system for determining carbon dioxide in carbonated orange juice beverages. The carbonated orange juice beverage sample is treated with alkali and acid before distillation. The overflowing carbon dioxide is condensed by the cooling absorption unit and absorbed by the reaction vessel, thus facilitating the determination of the carbon dioxide content in the carbonated orange juice beverage.

[0004] To achieve the above objectives, this utility model provides a distillation system for determining carbon dioxide in carbonated orange juice beverages, comprising a distillation unit, a cooling absorption unit, and a reaction vessel; the distillation unit is connected to the cooling absorption unit via a first conduit, and the cooling absorption unit is connected to the reaction vessel via a second conduit; the distillation unit is equipped with an inlet tube, a third delivery tube, and a fourth delivery tube, and each of the inlet tube, the third delivery tube, and the fourth delivery tube is equipped with a metering pump and an inlet control valve; an exhaust device is installed on the upper part of the reaction vessel.

[0005] The distillation unit includes a first tank and a heating base located at the bottom of the first tank. A motor is installed in the middle of the heating base, with the output shaft of the motor extending upwards. A permanent magnet is fixedly installed on the output shaft of the motor. A heating coil is installed on the outside of the motor on the heating base. A magnetic stirrer is movably placed in the center of the first tank. The first conduit, the sample inlet tube, the third delivery tube, and the fourth delivery tube are respectively connected to the first tank.

[0006] The first tank is made of non-metallic material, and a metal ring is installed at the bottom of the first tank.

[0007] The cooling absorption unit includes a cooling tank and a second tank. The cooling tank is used to inject coolant, and the second tank is located inside the cooling tank. The first conduit and the second conduit are respectively connected to the second tank.

[0008] The second tank is provided in multiple ways. Adjacent second tanks are connected in series by connecting pipes. The first conduit is connected to the first second tank and the second conduit is connected to the last second tank.

[0009] The exhaust device employs a vacuum pumping system.

[0010] It also includes a first container and a second container. The first container is connected to the cooling absorption unit through a first delivery pipe, and the second container is connected to the reaction vessel through a second delivery pipe. A metering pump and a liquid inlet control valve are also installed on the first delivery pipe and the second delivery pipe, respectively.

[0011] The first container is connected to the reaction vessel via a sixth delivery pipe, which is also equipped with a metering pump and an inlet control valve.

[0012] It also includes a third container and a fourth container, with the third and fourth delivery pipes connected to the third and fourth containers respectively.

[0013] Compared with the prior art, this utility model has the following technical effects:

[0014] 1. With the system of this utility model, the carbonated orange juice beverage sample is treated with alkali and acid and then distilled. The overflowing carbon dioxide is absorbed by both the cooling absorption unit and the reaction vessel, which makes it easy to determine the carbon dioxide content in the carbonated orange juice beverage.

[0015] 2. This invention uses a motor to drive a permanent magnet block to rotate, which in turn drives a magnetic stirrer inside the first container to rotate. The rotation of the magnetic stirrer agitates the solution, facilitating the release of carbon dioxide. Simultaneously, a heating coil heats the first container, further promoting the release of carbon dioxide.

[0016] 3. This utility model uses multiple second tanks connected in series to make carbon dioxide more fully absorbed.

[0017] The exhaust system employs a vacuum pump. Before measurement, the vacuum pump is turned on, and nitrogen gas is drawn into the first tank, the second tank, and the reaction tank through the sample inlet tube to replace the air inside these tanks. Because air contains carbon dioxide, replacing it with nitrogen makes the measurement data more accurate. Attached Figure Description

[0032] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0033] Example 1:

[0034] See Figures 1-2 A distillation system for carbon dioxide determination in carbonated orange juice beverages includes a distillation unit 10, a cooling absorption unit 40, and a reaction vessel 50. The distillation unit 10 is connected to the cooling absorption unit 40 via a first conduit 18, and the cooling absorption unit 40 is connected to the reaction vessel 50 via a second conduit 44. The distillation unit 10 is equipped with an inlet tube 90, a third delivery tube 21, and a fourth delivery tube 31. A metering pump 22 and a liquid inlet control valve 23 are installed on the inlet tube 90, the third delivery tube 21, and the fourth delivery tube 31. An exhaust device 80 is installed on the upper part of the reaction vessel 50.

[0035] In this embodiment, sodium hydroxide solution is injected into the cooling absorption unit 40, and barium chloride solution is injected into the reaction vessel 50.

[0036] Insert the injection tube 90 into the container containing the orange juice beverage solution, turn on the metering pump 22 and the liquid inlet control valve 23 on the injection tube 90, and measure by the metering pump 22. After measuring to the preset value, turn off the metering pump 22 and the liquid inlet control valve 23 on the injection tube 90.

[0037] Subsequently, hydrogen peroxide solution is injected into the distillation unit 10 through the third delivery pipe 21. During the injection of hydrogen peroxide solution, the metering pump 22 and the liquid inlet control valve 23 on the third delivery pipe 21 are opened. The metering pump 22 measures the solution, and after the preset value is reached, the metering pump 22 and the liquid inlet control valve 23 on the third delivery pipe 21 are closed. The distillation unit 10 must not leak air.

[0038] The vacuum level is slowly increased by the exhaust device 80 until no air bubbles are present, and the vacuum state is maintained.

[0039] Then, an acidic phosphate solution is injected into the distillation unit 10 through the fourth delivery pipe 31. When the acidic phosphate solution is injected, the metering pump 22 and the liquid inlet control valve 23 on the fourth delivery pipe 31 are opened. The metering pump 22 measures the solution. After the preset value is reached, the metering pump 22 and the liquid inlet control valve 23 on the fourth delivery pipe 31 are closed.

[0040] The mixed solution is distilled by distillation unit 10 to fully remove carbon dioxide from the orange juice beverage solution.

[0041] The overflowing carbon dioxide enters the sodium hydroxide solution in the cooling absorption unit 40 through the first conduit 18, condensing the gas. Simultaneously, the carbon dioxide is absorbed by the sodium hydroxide to form carbonate. The gas then enters the reaction vessel 50 through the second conduit 44. The barium chloride in the reaction vessel 50 precipitates the carried-out carbonate, preventing carbonate overflow.

[0042] After the measurement time is up, the distillation unit 10 is turned off, and the solutions in the cooling absorption unit 40 and the reaction vessel 50 are mixed. The carbon dioxide content in the sample is then determined by the mixed solution.

[0043] In this embodiment, see Figure 3The distillation unit 10 includes a first tank 11 and a heating base 12 located at the bottom of the first tank 11. A motor 13 is installed in the middle of the heating base 12, with the output shaft of the motor 13 extending upwards. A T-shaped connecting plate is installed on the output shaft of the motor 13, and a permanent magnet block 14 is fixedly installed on the T-shaped connecting plate. A heating coil 15 is installed on the outside of the motor 13 on the heating base 12. A magnetic stirrer 16 is movably placed in the center of the first tank 11. A first conduit 18, a sample inlet tube 90, a third delivery tube 21, and a fourth delivery tube 31 are respectively connected to the first tank 11. The motor 13 drives the permanent magnet block 14 to rotate, which in turn drives the magnetic stirrer 16 inside the first tank 11 to rotate. The rotation of the magnetic stirrer 16 stirs the solution, facilitating the overflow of carbon dioxide. At the same time, the heating coil 15 heats the first tank 11, further promoting the overflow of carbon dioxide. In this embodiment, the magnetic stirrer 16 is a cylindrical permanent magnet.

[0044] Furthermore, when the first tank 11 is made of a non-metallic material, such as transparent plastic or glass, a metal ring 17 is installed at the bottom of the first tank 11 to facilitate heating. The heating coil 15 is an electromagnetic coil, which heats the metal ring 17 inside the first tank 11 using the principle of an induction cooker, thereby heating and distilling the mixed solution inside the first tank 11.

[0045] In this embodiment, the cooling absorption unit 40 includes a cooling tank 41 and a second tank 43. The cooling tank 41 is used to inject coolant, and the second tank 43 is located inside the cooling tank 41. The first conduit 18 and the second conduit 44 are respectively connected to the second tank 43. The coolant in the cooling tank 41 cools the second tank 43, thereby condensing the mixed gas entering the second tank 43.

[0046] It should be noted that, in combination Figure 1 , 2 In this process, one end of the first conduit 18, located inside the second tank 43, is inserted into the sodium hydroxide solution, while the other end, located inside the first tank 11, is away from the mixed solution. One end of the second conduit 44, located inside the reaction vessel 50, is inserted into the barium chloride solution, while the other end, located inside the second tank 43, is away from the sodium hydroxide solution. Specifically, a cooling seat 42 is provided at the bottom of the cooling tank 41.

[0047] Example 2:

[0048] Based on Example 1, see Figure 2 Multiple second tanks 43 are provided, and adjacent second tanks 43 are connected in series by connecting pipes 45. The first conduit 18 is connected to the first second tank 43, and the second conduit 44 is connected to the second tank 43 at the end. By connecting multiple second tanks 43 in series, carbon dioxide is absorbed more completely.

[0049] In this embodiment, there are two second tanks 43.

[0050] Example 3:

[0051] In this embodiment, the exhaust device 80 can be a vacuum device, such as a vacuum pump or an air pump.

[0052] Example 4:

[0053] Based on embodiment 1, 2 or 3, it also includes a first container 60 and a second container 70. The first container 60 is connected to the cooling absorption unit 40 through a first delivery pipe 61, and the second container 70 is connected to the reaction tank 50 through a second delivery pipe 71. A metering pump 22 and a liquid inlet control valve 23 are also installed on the first delivery pipe 61 and the second delivery pipe 71, respectively.

[0054] The first container 60 is used to hold sodium hydroxide solution, and the second container 70 is used to hold barium chloride solution. The metering pump 22 and the liquid inlet control valve 23 on the first delivery pipe 61 and the second delivery pipe 71 facilitate the precise addition of sodium hydroxide solution and barium chloride solution to the second tank 43 and the reaction tank 50, respectively.

[0055] Furthermore, the first container 60 is connected to the reaction vessel 50 through the sixth delivery pipe 62. The sixth delivery pipe 62 is also equipped with a metering pump 22 and an inlet control valve 23 to facilitate the addition of sodium hydroxide solution into the reaction vessel 50.

[0056] Furthermore, it also includes a third container 20 and a fourth container 30, with the third delivery pipe 21 and the fourth delivery pipe 31 connected to the third container 20 and the fourth container 30, respectively.

[0057] The third container 20 is used to hold hydrogen peroxide solution, and the fourth container 30 is used to hold acidic phosphate solution, so as to facilitate the addition of hydrogen peroxide solution and acidic phosphate solution into the first tank 11.

[0058] The method of use or principle of this utility model:

[0059] See Figure 1 Before use, this utility model contains hydrogen peroxide solution in the third container 20, acidic phosphate solution in the fourth container 30, sodium hydroxide solution in the first container 60, and barium chloride solution in the second container 70.

[0060] During the measurement, firstly, the metering pump 22 and the inlet control valve 23 on the first delivery pipe 61 and the sixth delivery pipe 62 are opened to inject sodium hydroxide solution into the second tank 43 and the reaction tank 50. The solution is measured by the metering pump 22, and after reaching the preset value, the metering pump 22 and the inlet control valve 23 on the first delivery pipe 61 and the sixth delivery pipe 62 are closed. Next, the metering pump 22 and the inlet control valve 23 on the second delivery pipe 71 are opened to inject sodium hydroxide solution and barium chloride solution into the reaction tank 50. The solution is measured by the metering pump 22, and after reaching the preset value, the metering pump 22 and the inlet control valve 23 on the second delivery pipe 71 are closed.

[0061] Insert the injection tube 90 into the container containing the orange juice beverage solution, turn on the metering pump 22 and the liquid inlet control valve 23 on the injection tube 90, and measure by the metering pump 22. After measuring to the preset value, turn off the metering pump 22 and the liquid inlet control valve 23 on the injection tube 90.

[0062] Then, hydrogen peroxide solution is injected into the distillation unit 10 through the third delivery pipe 21. When the hydrogen peroxide solution is injected, the metering pump 22 and the liquid inlet control valve 23 on the third delivery pipe 21 are opened. The metering pump 22 measures the solution. After the preset value is reached, the metering pump 22 and the liquid inlet control valve 23 on the third delivery pipe 21 are closed.

[0063] The vacuum level is slowly increased by the exhaust device 80 until no air bubbles are present, and the vacuum state is maintained.

[0064] Then, an acidic phosphate solution is injected into the distillation unit 10 through the fourth delivery pipe 31. When the acidic phosphate solution is injected, the metering pump 22 and the liquid inlet control valve 23 on the fourth delivery pipe 31 are opened. The metering pump 22 measures the solution. After the preset value is reached, the metering pump 22 and the liquid inlet control valve 23 on the fourth delivery pipe 31 are closed.

[0065] The mixed solution is distilled by distillation unit 10 to fully remove carbon dioxide from the orange juice beverage solution.

[0066] The overflowing carbon dioxide enters the sodium hydroxide solution in the second tank 43 through the first conduit 18, where the gas is condensed. Simultaneously, the carbon dioxide is absorbed by the sodium hydroxide to form carbonate. Afterward, the remaining gas enters the reaction tank 50 through the second conduit 44, where it further absorbs carbon dioxide and the carbonate is precipitated by barium chloride.

[0067] After the measurement time is up, the distillation unit 10 is turned off, and the solutions in the cooling absorption unit 40 and the reaction vessel 50 are mixed. The carbon dioxide content in the sample is then determined by the mixed solution.

[0068] It should be noted that, in order to facilitate the removal of the solution from the second tank 43 and the reaction tank 50, and to facilitate the cleaning of the first tank 11, the second tank 43 and the reaction tank 50, the first tank 11, the second tank 43 and the reaction tank 50 adopt an openable structure, such as a threaded sealing structure similar to a covered cup, or a flange cover sealing structure.
