Praxair Inc. hosted the IQF (individually quick frozen products) Theater for attendees of the International Production & Processing Expo (IPPE), teaching attendees how to produce IQF products by using Praxair’s ColdFrontM Ultra Performance Flighted Freezer System. With more than 40 years of experience and knowledge built into the latest design of the Flighted Freezer System, processors are able to maximize yield and increase production capacity, while keeping quality high and freezing costs low.
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. This latest Flighted Freezer design has a track record of success at customer installations throughout the United States using either liquid carbon dioxide (CO2) or liquid nitrogen (N2). Either raw or cooked foods can be frozen into excellent quality IQF products using this system.
