Combining air pressurization technology with distribution design, the IJ White auto pressurization system automatically balances the pressure differential at theAuto Pressurization system infeed and discharge openings on spiral blast freezers. It is PLC controlled and monitored to reduce the amount of cold freezer air spilling from the low opening while controlling the amount of warm, moist air entering into the blast freezing system. With the APS system, blast freezers can increase the production time between coil defrosts.
