Clean-in-place (CIP) is an automated method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings, without disassembly. Repeatable, reliable, and effective cleaning is of the utmost importance in the distillery process, which is effectively a food grade environment. In order to adequately clean processing equipment, the equipment is designed with smooth stainless-steel surfaces and interconnecting piping that has cleanable joints. The chemical properties of the cleaning agents must properly interact with the chemical and physical properties of the residues being removed. Each of our vessels has a stainless-steel spray head suspended inside. We put pressurised liquid through this, which sprays the inside of each vessel. First, we pre-rinse with purified water to wet the interior of the vessel and remove residue. It also provides a non-chemical pressure test of the CIP flow path. Then a caustic solution is passed through to clean the vessel. A second rinse is performed before a mild acidic solution is passed through to remove mineral precipitates and protein residues. Lastly, a final rinse flushes out residual cleaning agents. Air is then blown through to remove moisture remaining after the CIP cycle.
