CIP Optimization of Your Brewery Cellar Through Use of Mixed-Peracids in Cold Sanitation & Washes

In a cold sanitizing process, temperate water is circulated through the CIP circuit with the addition of an EPA (Environmental Protection Agency) approved sanitizer. Mixed-peracid sanitizers (e.g. peroxyacetic acid [PAA], peroxyoctanoic acid [POOA], etc.) offer benefits beyond traditional peracetic acids in the brewing operation that make them a great choice for use in a cold-sanitizing process.

Benefits of using a peracid or mixed-peracid sanitizer in place of hot water as a sanitizer include:

• Simplified CIP Process - Single-step cleaning process eliminates the need for a separate acid wash rinse step.
• Energy & Water Reduction - The shorter CIP process requires less rinse water and reduces the total amount required to be heated.
• Reduced Chemical Concentration - In many cases, the total concentration of the chemistry required for cleaning is decreased, leading to less acid in the effluent stream.
• Reduced Venting - For vessels using an alkaline wash program with a CO₂ venting step a mixed-peracid product can allow for washing under CO₂ conditions, saving CO₂ consumption and time.
• Flavor Carryover - Leverage as a hard surface cleaner to eliminate flavor carryover when changing tanks between various products. This can shorten your normal CIP program required for changeovers. This is often most impactful when switching between products beyond beer, such as flavored seltzers.

In the case of Synergex™ Sanitizer & Disinfectant, this mixed-peracid blend incorporates a mineral acid which lowers the overall pH of the use solution and improves mineral solubility. This can be beneficial in reducing the need for separate acid washing steps in your wash schedule.
