The liquid nitrogen filling machine is mainly used to pressurize and reinforce thin-walled (aluminum, PET) containers such as mineral water, juice, iced tea and other beverages. Liquid nitrogen filling machines have a big market all over the world. It adopts a thinner container and is reinforced with liquid nitrogen pressure. On the one hand, it can generate internal pressure in the can/bottle to avoid shrinkage after cooling and deformation during packaging and handling.
Second, remove the air (especially oxygen) inside the jar/bottle, so that the product has a longer shelf life and better taste. Third, aluminum cans are not easy to rust, so they are suitable for refrigeration.
When this product is used, the vacuum liquid feeding pipe is connected with the liquid inlet of the filling machine. When filling with liquid nitrogen, the storage barrel is injected into the aluminum can through the thermal insulation infusion pipe and the thermal insulation filling head. The liquid nitrogen filling machine can be applied to the flexible packaging of food like nitrogen on the roof, which can remove oxygen, ensure the quality of goods, and make the packaging stronger.
Liquid nitrogen can replace the air at the top of non-carbonated beverage bottles by injecting liquid nitrogen into aluminum cans. Improve product quality stability and improve safety performance. Adding liquid nitrogen can increase the pressure in the bottle, prevent the bottle from being easily flattened, and reduce the weight of the bottle. This technology is widely adopted by many beverage production companies.
The main functional advantages of the liquid nitrogen filling machine are:
1. Improve the utilization rate of warehouse space - improve product stacking capacity and reduce the use area
2. Extend the shelf life - reduce the oxygen content to a lower level
3. Glass-to-plastic packaging—eliminates the personal hazard and weight of glass bottles
4. Maintain organic product quality - no preservatives to extend shelf life
5. Bottle sturdiness - maintains the original shape of the lightweight bottle
6. Hypoxic function - inert packaging to maintain product freshness
7. Eliminate flat bottles - increase the bottle pressure to eliminate the problem of flat bottles
8. Lightweight PET bottle--reduce the gram weight of PET to save cost and environmental protection
9. Reduce the use of oxygen - the saving performance of liquid nitrogen filling can be measured and replicated
10. Easy to label -- the hardness of the bottle wall is consistent, which improves the high labeling efficiency
In addition to the above, the liquid nitrogen filling machine is also widely used in condiments, edible oil, red wine, medicine, etc., for example, it injects liquid nitrogen into infusion products to generate gas nitrogen to control the residual oxygen content , to prevent explosion and eliminate hidden dangers of safety and product quality.
