The pressure increase ‘rigidifies’ the bottle, making it robust enough to stack. Is the same true for molecules Put the question to the test during this science experiment and see if liquid nitrogen (LN2) can be mixed with boiling water and. The trapped droplet expands as it vaporises and increases the internal pressure. These systems add a droplet of liquid nitrogen and trap it by immediately capping the bottle.
We supply the liquid nitrogen (LIN) needed for the LIN dosing systems commonly used in bottling facilities. Peak differential pressure increases of between 0.6 kPa and 12.114 kPa were observed. In addition, it is inert – thus protecting the drink against oxidation, which can lead to drink spoilage and lost revenues. For volumes of liquid nitrogen between 3.0 liters and 7.0 liters and water masses between 0.17 kg and 0.458 kg, the rate of pressurization varied between 0.03 kPa/s and 40 kPa/s. When liquid nitrogen vaporises, it expands to 682 times its liquid volume. Nitrogen is the perfect medium because it is available in liquid form. This problem can be avoided by pressurising the bottles. With thinner walls, weak bottles at the bottom of a pallet buckle under the weight of the bottles above, creating unsafe conditions and costly product losses. However, doing so has reduced the weight of PET polymers in the bottles, resulting in thinner, weaker bottle walls.Īfter filling, bottles must be stacked so they can be transported to customers. Over the past 20 years, plastic bottles have become thinner in line with environmental and cost pressures. Manufacturers of non-carbonated beverages (water, juices, teas, etc.) generally rely on PET (polyethylene terephthalate) to make their drinks bottles.
