How to Clean Brewery Pipes

In a brewery, pipes are complex parts that require thorough cleaning. We have to take full advantage of mechanics to improve cleaning because flow conditions have a big impact. If the flow rate is too slow, the liquid tends to stratify, and then the flow rate starts to slow down from the center to the edges. In this case, it is difficult to remove the dirt. Therefore, when cleaning the pipeline, be sure to ensure high speed to generate eddy currents.

The relationship between pipe diameter and cleaning fluid flow.

Pipe diameter flow

DN<50 3-4m/s

50<DN<100 2m/s

100<DN<1.5m/s

Also, if the straight pipe has a T-joint, the flow rate should be increased to achieve the minimum cleaning intensity, which is 1.5 m/s. Therefore, it is best to remove the T-joint after quick pasteurization or sterilization filtration of the pipe. If a T-connector is required, the length of the connector should be as short as possible and close to the main line to avoid dead ends. Also, the flow of cleaning fluid and mash/wastewater/beer should be reversed for better cleaning.
