Praxair Inc. has added the newest design of its ColdFront ultra-performance spiral freezer to its other cryogenic freezing and chilling systems in the Praxair Food Laboratory. This improvement allows customers to test their food products on full-sized equipment using ideal production parameters for efficient cryogen usage, achieving maximum productivity. The ColdFront ultra-performance spiral freezer will also be on display in booth 5631 at the International Production and Processing Expo (IPPE) in Atlanta this January.
The newly designed ultra-performance spiral freezer utilizes direct cryogen injection of either N2 or CO2 for maximizing heat transfer. Enhanced horizontal vapor flow provides additional cooling potential that would otherwise be under-utilized. The improved vapor-balance system minimizes air and moisture infiltration into the system reducing cryogen consumption. These features, combined with wider belts than those found on similarly sized freezers, result in efficient utilization of cryogen while providing for maximum production capacity in a minimal footprint. In addition, all Praxair freezing and chilling systems designs include enhanced sanitation features, making clean-up quick and thorough.
