Liquid Nitrogen Dosing
Liquid Nitrogen Dosing (LN2): Why is it used?
The process of liquid nitrogen dosing serves various essential purposes, contributing to enhanced packaging quality and cost-efficiency. Here are the primary reasons for dosing with liquid nitrogen:
- Improved Rigidity and Weight Reduction: Liquid nitrogen dosing enhances the structural integrity of packaging materials, making them more robust and rigid. This, in turn, reduces packaging costs by requiring less material.
- Extended Shelf Life: The incorporation of liquid nitrogen can significantly extend the shelf life of various products by reducing the oxidization of the product, ensuring that they maintain their quality for extended periods. This preservation benefit is particularly vital for food and beverages.
- Enhanced Product Quality: Nitrogen dosing can improve the overall quality of products. In particular, nitro-infused beverages acquire a luxurious, thick, and creamy texture that enhances the drinking experience and intensifies flavor.
LN2 Dosing Applications:
- Liquid nitrogen dosing is particularly well-suited for pressurizing various types of containers, including PET and PP bottles, aluminum cans & and bottles, and non-carbonated beverages.

How Does a Liquid Nitrogen Dosing Machine Work?
A Liquid Nitrogen Dosing Machine introduces a controlled quantity of liquid nitrogen into a compatible container as part of the packaging process.
The dosing operation is positioned at the required stage of the packaging line according to the application. After dosing, the container continues through subsequent packaging operations such as capping, sealing or other downstream processes.
The actual dosing configuration depends on factors such as:
- Product characteristics
- Container type
- Container format
- Packaging process
- Required production rate
- Intended LN2 application
This allows the LN2 Dosing Machine to be incorporated into different packaging line configurations.
LN2 Dosing Machine for Container Pressurization
Container pressurization is an important application of liquid nitrogen dosing.
When a controlled quantity of liquid nitrogen is introduced into a suitable container, the nitrogen transitions and creates pressure inside the package. This can help improve container rigidity and packaging performance.
Spheretech identifies PET and PP bottles, aluminium cans and bottles, and non-carbonated beverage applications for LN2 pressurization.
Liquid Nitrogen Dosing for Food & Beverage
Liquid nitrogen dosing can support different food and beverage packaging applications where controlled nitrogen dosing is required.
Spheretech identifies applications including edible and cooking oils, coffee, tea, beer, nuts, wine, fruit juice, vitamins, soft drinks, sauces, snacks and coffee seeds.
The appropriate dosing application depends on the product characteristics, packaging format and production requirements.
Liquid Nitrogen Dosing for Inerting
Inerting is an application where nitrogen is introduced into a suitable packaging environment to reduce oxygen exposure.
For products that are sensitive to oxidation, controlled nitrogen dosing can support packaging processes designed around product protection and quality preservation.
The appropriate dosing process should be determined according to the product and packaging requirements.
Liquid Nitrogen Dosing for Nitro-Infused Beverages
LN2 dosing can also be used for suitable nitro-infused beverage applications.
Nitrogen can contribute to the characteristic texture and sensory properties associated with nitro-infused beverages. Spheretech identifies nitro-infused beverages as one of its liquid nitrogen dosing applications.
Liquid Nitrogen Doser for Automated Packaging Lines
A Liquid Nitrogen Doser can be integrated with other packaging equipment to create a continuous automated packaging process.
A typical packaging workflow may include:
FILLING → LN2 DOSING → CAPPING → SEALING → LABELLING → CODING → CASE PACKING
