Choosing the correct liquid nitrogen (LN2) doser is one of the most critical decisions you'll make for your canning or bottling operation. The right system not only ensures container rigidity and a pristine package but also protects product quality by displacing oxygen.
At JoyCan, we offer a range of models, including the UltraDoser 150S, UltraDoser 2KA, CryoDoser Flex Craft Custom, and CryoDoser Flex Pack Premier, designed to integrate with different production speeds, filler types, and nitrogen supply setups.
This detailed guide will help you select the ideal doser for your specific needs, referencing technical specifications and industry best practices.

1. Start with production line speed
The first and most fundamental question is: What's the maximum speed of your filler in containers per minute (CPM)? This metric is the primary filter for selecting a doser, as each model is engineered for a specific speed range.
- UltraDoser 150S: Built for lower-speed operations, this doser handles up to 150 CPM. It's a robust entry-level solution perfect for small-scale operations, craft brewers, or pilot lines.
- CryoDoser Flex Craft Custom: This model is designed for a higher range, capable of up to 200 CPM. It's a popular choice for growing craft beverage companies and linear filling lines with multiple fill heads.
- UltraDoser 2KA and CryoDoser Flex Pack Premier: Both of these are high-speed solutions, accommodating up to 2,000 CPM. They are engineered for large-scale, high-throughput packaging lines where efficiency and reliability are paramount.
2. Evaluate your filler type & functionality
Once you've determined your speed requirements, the type of filler—whether it’s a rotary or linear system—and specific required features will further narrow your choice.
- Rotary fillers: These fillers are common in high-speed bottling and canning lines.
- For speeds up to 150 CPM, you have a choice between the UltraDoser 150S or the CryoDoser Flex Craft Custom.
- For speeds between 150-200 CPM, the CryoDoser Flex Craft Custom is your best option.
- For high-speed rotary lines (between 200-2200 CPM), the UltraDoser 2KA is specifically designed for seamless integration and high-performance, with its advanced PLC and control features.
- Linear fillers: These are often used for lower-speed and specialized filling operations.
- For single or dual-head linear fillers, the UltraDoser 150S is typically sufficient.
- For linear fillers with three or more fill heads, the CryoDoser Flex Craft Custom is required. This is due to its Variable Dosing capability, a crucial feature that allows for different dose durations for each container, which is often necessary to compensate for slight variations in fill heads or line flow.
3. Consider your liquid nitrogen supply setup
The final major factor is your nitrogen supply. Dosing systems operate based on inlet pressure, which varies depending on whether you're using a mobile dewar or a bulk storage system.
- Mobile dewars: The UltraDoser models (150S and 2KA) are designed to work with lower-pressure systems, typically accepting up to 22 psi. This makes them an ideal match for mobile liquid nitrogen dewars (e.g., Dura-Cyl) commonly used in smaller operations.
- Vacuum Insulated Piping (VIP) systems: The CryoDoser Flex models (Craft Custom and Pack Premier) can accept a higher inlet pressure of up to 100 psi. If your facility is connected to a bulk storage tank via a vacuum insulated piping system, these models are the most efficient and reliable choice. This higher pressure capability minimizes LN2 loss and ensures a continuous, steady flow for consistent dosing.
4. Fine-tune with essential accessories
Once you've selected the core doser model, you can optimize its performance with a range of accessories.
- Sensor types: Different sensor types (e.g., electronic or pneumatic) can be selected for container detection and line speed synchronization.
- Mounting hardware: Customizable mounting brackets and stands ensure the doser head is perfectly positioned over your filling line for maximum dosing accuracy.
- Purge options: Gaseous nitrogen purge systems are critical for preventing frost and ice buildup around the dosing nozzle, which can disrupt operation.
- Nozzle sizes: A variety of nozzle sizes are available to fine-tune the dose volume, allowing you to achieve the precise amount of LN2 needed for your container and product type.
What is a Liquid Nitrogen Doser?
A liquid nitrogen doser is a device that injects a small, precise amount of liquid nitrogen into a container just before it is sealed. The liquid nitrogen then rapidly vaporizes into a gas, creating pressure to add rigidity to the container and purging oxygen to extend shelf life.
What are the benefits of using a liquid nitrogen doser?
Using a liquid nitrogen doser provides several key benefits for packaging, including improving the structural integrity of thin-walled containers, reducing oxygen content to extend a product's shelf life, and creating a nitrogen-infused product with a unique mouthfeel.
How does a liquid nitrogen doser work?
A liquid nitrogen doser works by using sensors to detect the presence of a container and the line speed, then opening a valve to dispense a precise drop of liquid nitrogen into the container before it is capped or seamed. This process takes advantage of liquid nitrogen expanding to approximately 700 times its volume when it vaporizes, which then displaces oxygen and pressurizes the container.
