　　Chengdu Zhuoda Yuntong - Easy Can Liquid Nitrogen Filling Machine

　　Currently, beverages on the market are mainly sold in the form of two-piece cans, three piece cans, PET bottles, and paper box packaging. Most two-piece cans are made of aluminum, which is lightweight and can effectively reduce transportation costs. The disadvantage is that they are prone to collapse, especially when filling non carbonated beverages. Most three piece cans are made of iron and are mainly used for filling non carbonated beverages. Their characteristic is that they are sturdy and not prone to collapsing. However, the weight of three piece cans is relatively heavy, and in recent years, the price of iron has increased, resulting in increased manufacturing costs.

　　When there are defects in the application, someone will always come up with ways to solve these problems. For example, how to reduce the cost of three piece cans and how to minimize the situation of two piece cans collapsing. Therefore, a method has emerged - liquid nitrogen drip technology.

　　If you want to reduce the cost of cans, you can change the three piece can to a two-piece can. Because aluminum cans are lighter than iron cans, a typical aluminum can weighs 13 grams, while an iron can of the same capacity requires 45 grams. If you want to reduce the occurrence of flat cans, you can use liquid nitrogen drip. Because the dripping of liquid nitrogen creates internal pressure inside the tank, the product can enter the sterilization pot and undergo long-term sterilization at 121 ° C, without collapsing the tank after cooling, and without deformation during packaging and handling. The specific operation is to use modern liquid nitrogen injection technology to accurately inject liquid nitrogen at -196 ° C before entering the sealing after filling. Then, immediately seal it, and liquid nitrogen absorbs heat in a short period of time, expanding its volume 700 times and becoming gaseous nitrogen. There are two benefits to doing this, which are to drive away the air (especially oxygen) inside the tank and prolong the shelf life of the product; Aluminum cans will not rust and are suitable for refrigeration.

　　In addition to packaging made of metal, liquid nitrogen dripping into PET bottles and flexible packaging also has a similar effect. Dropping liquid nitrogen into PET bottles produces gaseous nitrogen. One is to replace the air at the top of the bottle, which makes the quality of the product more stable and safer. The second is to generate internal pressure, increase strength, prevent bottle collapse, and reduce bottle weight. For example, cola, PepsiCo purified water, mineral water, an 18 gram bottle only requires 13 grams or less. The hand feel after nitrogen injection is no less than that of an 18 gram bottle. There are also the Meizhiyuan series, the 10 part V series, the Fruit and Milk Excellence series, and so on.

　　In flexible packaging, adding nitrogen and deoxygenation to the roof box can extend the shelf life of the product and make the packaging harder. Injecting nitrogen into seasonings, edible oils, red wine, and medical infusion products can generate gaseous nitrogen, control residual oxygen levels, and eliminate quality hazards.
