Brew vessels, yeast and fermentation tanks as well as filtration systems must be cleaned during the brewing procests to ensure sterility. To avoid disassembly, the cleaning of the entire pipeline system is regularly done in place (Cleaning In Place).
The treatment agents for the flushing processes include caustic soda and various acids (usually phosphoric acid, nitric acid) with their respective additives; disinfectants such as hydrogen peroxide or peracetic acid are also used. The use of tenside free detergents in modern flushing processes can help save time and water.
The process is largely fully automatic exerting equally high requirements on the dosing system.
The structure of the system is marked by absolute corrosion resistance, leak-tightness and reliability in handling the very aggressive chemicals. Last not least, economy ensured by the great dosing accuracy and durability of the pumps is also an important factor.
The design of the dosing equipment used for CIP cleaning requires the pumps and the necessary accessories to be wall-mounted on respective mounting panels. The pumps then suck the chemicals directly from the supply containers erected next to or below the dosing system. To further enhance the safety standard, the dosing systems can be equipped with additional splash guards.
