The liquid nitrogen injector from liquid Packaging Solutions is ideal for the pressurization of both plastic containers and aluminum cans.
In addition, the injector can be used for inserting headspace in containers such as wine bottles.
The injector is designed to be quickly installed and removed from a filling line. The compact unit is self contained in two attached control boxes housing the electrical and nitrogen dosing components respectively. The system uses a sensor and a series of valves and nozzles to inject a preset volume of liquid nitrogen into the container at a given speed. The sensor detects the presence of a container and a PLC calculates the container speed, which in turn directs the proper time of valve to open.
As the line speeds up, more time of valve opening to ensure proper pressurization or blanketing.
