A key cryogenic agent in the cooling, chilling and freezing of food products, carbon dioxide protects the taste and texture of your produce by maintaining proper temperature control.
Nitrogen is a key cryogenic agent in cooling, chilling and food freezing processes. Because of its extremely cold temperatures, liquid nitrogen is an essential part of immersion freezing, the fastest method known for producing individually quick frozen (IQF) foods.
From apples to zucchini, Praxair systems efficiently freeze and chill a wide variety of produce. Our individually quick frozen (IQF) freezing systems gently tumble individual food pieces to maximize cryogen exposure for a thorough and rapid freeze. If your product is more delicate, our cryogenic systems control temperatures so that fruits and vegetables are chilled to firm and cut cleanly with less damage.
Removing heat with carbon dioxide snow is an economical, precise way to cool your produce at any point in your production. Praxair snow dispensing devices are available in a wide range of sizes and types, and can stream CO2 snow from any orientation. Plus, the snow particles are much more consistent and uniform, allowing the most effective snow cooling available.
Extend the shelf life of fresh, pre-packaged produce using modified atmosphere packaging (MAP). Consumers continue to demand fresh, convenient products, and MAP helps ensure that your produce stays at its peak quality for longer.
CO2 in greenhouse growing increases productivity through improved stem strength, higher fruit yields and earlier flowering. Liquid CO2 is low-cost and easy to install, and can optimize your greenhouse growing.
At Praxair, we understand how cryogenic freezing systems affect your product, and how making changes to your current method could benefit your operations. We can analyze your process and provide you with recommendations to improve the quality and consistency of your food product.
We ensure that our customers get the right products, optimized for their operations. And we back them up with 24/7 support services that include total system review and start up, customized production and operator training.
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.
ColdFront™ Ultra Performance Tunnel Freezer
Increase throughput of your produce and boost productivity in the same or smaller footprint than existing cryogenic operations.
ColdFront™ Ultra Performance Spiral Freezer
With improved distribution control and vapor circulation, the ultra performance spiral freezer adds additional cooling power to extract more heat from your produce, faster.
ColdFront™ Ultra Performance Immersion Freezer
Prevent your produce from freezing together during the individually quick frozen (IQF) process. Our ultra performance immersion freezer helps you maintain precise product attributes while meeting the needs of your customers.
ColdFront™ Ultra Performance Flighted Freezer
Improve your individually quick frozen (IQF) capabilities with our flighted freezer. Flighted conveyors gently tumble produce pieces, keeping them separate and maximizing exposure to cryogen for quick and thorough freezing.
ColdFront™ Cryo-Saver Tunnel Freezer
The new ColdFront™ cryo-saver tunnel freezer approaches cryogenic freezing from an entirely new angle. The cryo-saver tunnel freezes and chills a wide variety of produce and minimizes the infiltration of processing area air improving the overall operational effectiveness.
ColdFront™ Continuous Rotary Chiller
