How can I better understand my nitrogen usage?

Chris Johnson
Food Technology Specialist

Measuring the quantity of liquid nitrogen (LIN used during food freezing and chilling is vital to remaining operationally competitive. Unlike other materials, LIN can be troublesome to measure continuously, so it’s important to implement a daily LIN use tracking program. This data provides a benchmark against which to measure your LIN use. The amount of LIN used continuously is less telling than the changes in use as time progresses. Did the new startup operating procedure make the freezing process more efficient? Did changing from an insulated pipe to a vacuum-jacketed pipe really save costs this year? Questions like these can be answered in pursuit of continuous improvement if LIN is tracked daily.

How do you get started on tracking your LIN usage? Air Products’ Food Technology Specialists connect customers to the cost side of using LIN with daily tracking tools while providing the support and training to improve usage. Air Products’ Freshline® solutions reflect our continuing commitment to the food industry, providing a single point of reference for customers. For more information, call 800-654-4567.
