Carbonated beverages
Quality inspection of carbonated beverages
Gasporox offers solutions for quality inspection of beverages so that you can safely say that the beverage is up to best standard.
Gasporox has worked for many years with developing the non-destructive and non-intrusive special technique called TDLAS, Tunable Diode Laser Absorption Spectroscopy. This technique allows for beverage manufacturers to have 100 % precise inline control of their beverage packages. The result is that producers can increase their production output and efficiency by not having to do destructive and time-consuming testing, but also to be able to control 100% of the packages without throwing away the inspected and cleared packages. The sensors represent a range of high-performance inspection sensors for machines such as bottling and filling machines and are capable of measuring packs of almost any shape, size, material, or application. With their easy to operate design, speed, size, and capacity, the Gasporox GasSpect and LeakSpect series offer new levels of quality inspection.
Application description
The transmitted laser light is sent through the headspace of the container and the signal is picked up by the detector. This can be done either in static mode when the bottle is standing still or in dynamic mode when the beverage package is moving on a conveyor belt.
Below we are providing some examples of measurements done of different bottle types with different transmission levels and these tests have been done on three different concentrations in headspace 20%, 40% and 100% and measuring pressure at the same time. For specific bottle-applications measurements are optimized according to customer specifications, bottle type and machine speed.
| Parameters | |
|---|---|
| Bottle material: | PET, glass (transparent, blue, green, amber) |
| Gas: |
Oxygen concentration 0,1-100% Carbon dioxide 0,1-100%, pressure 0,5-8 bar. |
| Transmission: | > 1% of the laser light |
| Example | Size | Material | Neck Diameter | Transmission | Internal Pessure | Headspace concentration | Measuring time | Accuracy |
|---|---|---|---|---|---|---|---|---|
| Carbonated water | 500 ml | PET | 30 mm | 25% (high) | 1-2 bar | 20 – 40 -100% CO2 | 300 ms | +/- 100 mbar (25 bar) +/- 2% CO2 |
| Beer | 500 ml | Glass | 25 mm | 8% | 2-3,5 Bar | 40-100% CO2 | 300 ms | +/- 100 mbar (30 bar) +/- 1% CO2 |
| Sparkling wine | 500 ml | Dark Glass | 28 mm | 5% | 2-4 Bar | 20-40-100% CO2 | 300 ms | +/- 100 mbar +/- 3% CO2 |
Technology
The Gasporox optical gas sensors are built on more than 25 years of development and refinement in industrial laser-based gas measurement. The system uses Tunable Diode Laser Absorption Spectroscopy (TDLAS), a highly reliable and precise method for non-destructive headspace gas analysis.
Developed by Gasporox in collaboration with its technology partners, this laser sensor technology is widely used in demanding industries such as pharmaceuticals, petrochemicals, and energy.
Gasporox’s laser-based headspace analysis has been successfully deployed for over a decade in pharmaceutical manufacturing. It is integrated into fully automated inspection systems and benchtop instruments for 100% in-line and laboratory testing of vials, ampoules, and other parenteral packaging formats. The performance and robustness of the system have been validated through extensive real-world use.
