The liquid nitrogen dosing system machine is an intelligent industrial device specifically designed to quantitatively and precisely inject liquid nitrogen (LN2) into packaging containers of food and beverages. It combines the ultra-low temperature (-196°C) properties of liquid nitrogen with automated control technology, and is widely used in various fields such as food, beverages, pharmaceuticals, and industrial manufacturing.
The liquid nitrogen doser machine primarily consists of core components such as the liquid nitrogen storage tank, filling control system (PLC, touch screen), metering device (flow meter), conveying pipeline (vacuum insulated pipe), and filling head (nozzle).
The liquid nitrogen injection machine injects liquid nitrogen before filling and sealing food packaging containers (such as cans, PET bottles, and aluminum cans). Upon vaporization and expansion, the liquid nitrogen displaces oxygen inside the packaging, reducing residual oxygen levels and extending product shelf life. It also generates internal pressure to maintain the packaging's round shape and prevent collapsed cans. The liquid nitrogen filling machine from Sichuan Aosituo is particularly suitable for the food and beverage industry for nitrogen injection, pressurization, oxygen removal, and preservation of packaged products.
