iqf food freezing using liquid Nitrogen or cryogenic Carbon Dioxide
Select the Best for IQF
Lock in moisture, preserve flavor and ensure proper texture with the right system for individually quick frozen (IQF) products. Ideal for small products or those that are wet, sticky or difficult to handle such as diced meats, produce and seafood, our ColdFront™ ultra performance flighted freezer provides maximum cryogen exposure — gently tumbling your products to produce excellent quality in IQF products. Our flighted freezer system helps processors maximize yield and increase production capacity while maintaining a high level of quality while lowering freezing costs.
Quick Crust Freeze
In order to produce the highest quality IQF product, the Praxair system exposes the product to cryogen at the freezer entrance ensuring a quick crust freezing. Short individual belt flights gently tumble foods for reduced fines and deliver even, quick freezing on all surfaces. Yield is also maximized through direct cryogen injection at key points throughout the freezer tunnel. Additionally, a wider belt width results in shorter tunnel lengths, allowing processors to maximize throughput while conserving valuable floor space.
Our latest flighted freezer design has a track record of success at customer installations throughout the United States using either liquid carbon dioxide (CO2) liquid nitrogen (N2). Either raw or cooked foods can be frozen into excellent quality IQF products using this system.
Sanitation is a Snap
The ultra performance flighted freezer, like all of Praxair’s temperature control systems, meets USDA sanitary guidelines. The freezer offers accessibility and a sanitary design allowing easy cleaning and maintenance. Inside the freezer, serpentine belt systems with cold belt capabilities provide excellent product release. For complete accessibility during clean-up and maintenance, vertical doors on both sides of the freezer swing out of the way to allow open access to the freezer interior. Product guides and scraper bars are also removable for cleaning and additional access. The user-friendly design allows the operator to see the entire interior floor of the freezer, making debris easier to locate and remove. Belt motors and drives are also located outside of the freezer for ease of maintenance and service.
Additionally, customers can customize their production to meet changing demands, economic conditions, product supply and type of cryogen used. Praxair food laboratory analyses ensure properly-sized equipment and offer recommended operational parameters to maximize product quality and meet production goals. The Praxair ColdFront™ ultra performance flighted freezer system is suitable for a wide variety of food products including most seafood, meat and poultry portions, diced foods, vegetables, berries, pizza toppings, processed foods, cheese and other similar items when individual, free flowing frozen food pieces are required.
