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.

Characteristics :

1. Nitrogen positive pressure protection-the nozzle is protected by dry nitrogen positive pressure to prevent frost and ice blocking inside the nozzle 2. The exhaust port is excluded from the top and connected to the outdoor through a vacuum tube (optional) 3. Adopt differential pressure liquid level gauge-high liquid level accuracy, tank has gas-liquid separation function, realize pressureless filling 4. Accurate nitrogen injection-provides stable and accurate nitrogen injection 5. Individual filling-interval filling mode below 300CPM 6. Individual filling or continuous filling-the speed can be set by the user 7. Vacuum insulation technology-improve the use efficiency of liquid nitrogen 8. Soft filling compatible-suitable for hot filling, powder, and granular, edible oil products 9. Micro-filling technology-the consistency and accuracy of nitrogen injection cover all line speeds
