This system will accurately calculate the liquid nitrogen, and inject the liquid to Can or Bottle. Once the liquid nitrogen been injected into Can or Bottle will quickly absorb the heat and turns into gas nitrogen, the volume will expand 700 times larger. The gas nitrogen not just displace the remain oxygen inside the Can, also generate the Can inner pressure to prevent the sink Can.
