Food grade lubricants are used in various parts of the brewing process, from grain handling to product packaging. Most breweries used low-pressure compressed air to move grain from the delivery truck to the storage silo, and from the silo to the brewing kettle. The compressed air used to move the grain should be produced in a compressor that uses a food grade compressor fluid. That assures that no trace of a non-food grade lubricant gets into the product from the grain. The bearings in any augers used to convey other components must be lubricated with food grade grease to prevent contamination of the components with non-food grade lubricants.
The pumps used to transfer the water that goes into the brewing process should have food grade oil or grease in their bearings. This will prevent any trace of non-food grade lubricant from entering the product with the water.
Once the product is finished, it must be packaged. Although kegs are typical for bars or large parties, the most common packaging is bottles or cans. In either case, the conveying of the empty containers must be done with equipment lubricated with food grade lubricants. The equipment used to move the empty cans or bottles from pallets to the packaging line typically has many grease-lubricated bearings. Those bearings should be lubricated with food grade grease to avoid possible contamination of the containers with a non-food grade lubricant. Even the process of boxing and stretch-wrapping the filled cans or bottles should use food grade lubricants in order to avoid any possibility of contamination of the filled containers.
