Compressed air is a dairy processor's fourth utility
High-quality compressed air, which can be considered the fourth utility (after gas, water and electricity), is critical for providing food products that are not only cost-effective to process but safe to eat. Compressed air may be used in multiple operations throughout a typical dairy plant.
Safe Quality Food (SQF) is the first certification scheme under the Global Food Safety Initiative (GFSI) that has officially started mandating the testing of compressed air used in the food manufacturing process in the United States. GFSI and the SQF Code state that compressed air used in the manufacturing process shall be clean and present no risk to food safety. Compressed air used in the manufacturing process shall be regularly monitored for purity.
