Liquid nitrogen filling machine is specially designed for medium and low speed production lines (edible oil, drinking water,food,etc)
A multi-functional nitrogen injection system designed to accurately inject liquid nitrogen into each container. The injected liquid nitrogen is then vaporized to form an internal pressure, which increases the stacking load rate of the container, and at the same time pushes out the oxygen in the container for the purpose of inerting and oxygen isolation.

Operating Principle :
Liquid nitrogen (LN2) is first transferred from the storage tank to the nitrogen injection head through the vacuum insulation tube.
The first sensor detects the line speed, the second sensor senses the container, and calculate the required liquid nitrogen injection volume based on the container speed.
Once the container is sensed, the filling valve is opened and a fixed amount of liquid nitrogen is injected.
The entire process is controlled by the programmable logic controller ,sensor and human-machine interfac
