What is the recommended flow rate for pumping chemicals through beer lines for cleaning?

The recommended flow rate for pumping chemicals through beer lines for cleaning is 2 gallons per minute. This flow rate strikes a balance between effective cleaning and maintaining the integrity of the beer lines.

At this flow rate, the cleaning solution is adequately circulated through the lines, ensuring that all residues, biofilms, and deposits are thoroughly removed. It allows the cleaning chemicals to make contact with the inner surfaces of the lines long enough to dissolve and lift contaminants without causing excessive turbulence, which could potentially harm the lines or the fittings.

Using a flow rate that is too low may result in ineffective cleaning, as the chemicals might not reach all parts of the beer lines adequately. Conversely, a flow rate that is too high could lead to decreased contact time, preventing the cleaning agents from working effectively and risking damage to sensitive components of the system. Thus, a flow rate of 2 gallons per minute is ideal for achieving optimal cleaning results while maintaining the safety and longevity of the beer dispensing system.
