CIP stands for "clean-in-place," which is a method of cleaning the interior surfaces of a brewery's equipment without disassembling it.
The entire CIP process is typically automated and controlled by a programmable logic controller (PLC) that regulates the flow and temperature of the cleaning solutions.
Here are the general steps involved in a CIP process in a brewery:
Pre-rinse: The equipment is first rinsed with water to remove any loose debris, such as grain or hops.
Alkaline cleaning: An alkaline cleaning solution, usually containing sodium hydroxide, is circulated through the equipment to dissolve any organic matter, such as yeast or protein, that has adhered to the surfaces.
Rinse: The equipment is then rinsed thoroughly with water to remove any remaining cleaning solution.
Acid cleaning: An acid cleaning solution, usually containing phosphoric acid, is circulated through the equipment to remove any mineral deposits, such as calcium or iron, that have accumulated on the surfaces.
Rinse: The equipment is again rinsed thoroughly with water to remove any remaining cleaning solution.
Sanitization: A sanitizing solution, usually containing a combination of hydrogen peroxide and peracetic acid, is circulated through the equipment to kill any remaining microorganisms that could contaminate the beer.
Final rinse: The equipment is given a final rinse with water to remove any remaining sanitizing solution.
Post-rinse: Finally, the equipment is inspected to ensure that it is clean and ready for use in the brewing process.
CIP (Clean-in-Place) systems are used in various industries, including food and beverage, pharmaceutical, and dairy, to clean and sanitize processing equipment without disassembling it.View More
These systems have a single tank that contains the cleaning solution, and the solution is circulated through the system using pumps and piping.View More
These systems have two tanks, one for cleaning solution and the other for rinse water. The cleaning solution is first circulated through the system, and then the rinse water is used to remove any remaining cleaning solution.View More
