Industrial applications for the food & beverage industry


Freezing & Chilling

We offer a full product line of freezing and chilling equipment, and can design and build a custom system to meet your specific need. With Praxair, you can count on a system designed to maximize both yield and production.


Flour & Dough Cooling

Optimum dough temperature is critical to most bakery operations. Our flour and dough cooling systems provide precise, yet easy-to-operate, methods to achieve the desired temperature.


Meat Mixing

Heat generated during mixing and grinding accelerates bacterial growth and leads to off-flavors, decreased shelf life and spoilage. Our cryogenic meat mixing systems slow bacterial growth and assure uniformity of temperature, helping you maximize shelf life and product quality.


CO2 Snowing

Cool your food products with carbon dioxide snow. Our CO2 application systems are an economical and precise way to remove heat. With a wide range of snowing applications, you can determine the exact amount, pattern and shape you need to meet your cooling requirements.


Modified Atmosphere Packaging (MAP)

Extend the shelf life of your meat, baked goods and produce. With over 200 specialty gas blends for food packaging, we can help food processors and packers select the right option to fit their specific needs.


Beverage Applications

Praxair provides carbonation services and gases along with other processing systems to help reduce operating costs, improve operational efficiency and achieve higher quality products from your beverage lines. Learn more about our applications for beverage carbonation and dissolved oxygen control.


Greenhouse Growing

Improved greenhouse growth can be achieved with the effective use of carbon dioxide. Using liquid CO2 from Praxair offers many advantages to growers including purity of product, reduced crop damage, no heat or moisture production, better control of CO2 levels and the flexibility to introduce CO2 within the plant canopy at any time.



Praxair oxygen lets fish farmers increase tank capacity with enhanced growth rates and fish density. Our systems also provide great results for shrimp and fish farming — healthier ponds and greater yield even with an accelerated growth cycle.

After the harvest, the condition of the ponds can also be improved with Praxair oxygen systems for aeration to reduce BOD and carbon dioxide systems for buffered pH balance. Water & Wastewater Treatment


Controlled Atmosphere Stunning

Improving product quality, supporting your animal handling policies and enhancing the worker environment are all achieved with the Praxair CAS system for broiler and turkey processing.
