Carbon dioxide is a key cryogenic agent in cooling, chilling and freezing applications, protecting the taste and texture of your food products by maintaining proper temperature control. Carbon dioxide also reduces the need for preservatives in packaged products, and is the essential ingredient for fizz in your carbonated beverages.
Nitrogen is a key cryogenic agent in cooling, chilling and food freezing. Because of its extremely cold temperatures, immersion freezing in liquid nitrogen is the fastest freezing method known for producing individually quick frozen (IQF) foods. Nitrogen also plays a key role in reducing spoilage, discoloration and off–flavors, while giving strength to retail packaging.
Critical for life, oxygen is used in aquaculture to deliver the dissolved oxygen levels that are needed for high production levels and fish health. Praxair oxygen is also key to providing increase dissolved oxygen levels for enhanced aeration and aerobic digestion in food wastewater streams.
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.
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.
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.
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.
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.
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.
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
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.
Our Food Technologies Lab is a full-time facility, staffed by dedicated and experienced food scientists who work with you to analyze your process, determine equipment specifications, recommend production parameters, and provide fact-based information to improve the quality and consistency of your product.
The Praxair Total System Approach focuses on getting your system designed, installed, tested, and quickly up and running to meet your operation needs.
At Praxair, we help you optimize every step of your process. From helping you install, monitor and manage your gas supply, to recommending applications to help you achieve the level of productivity and product quality you require.
