To prevent foam powder from cake, it must be occasionally what?

• A. Circulated
• B. Heated
• C. Shaken
• D. Filtered

Answer: (A)

Keeping the foam powder in motion prevents it from settling and forming a hard cake. When powder sits, particles settle and can clump together, making re-dispersion difficult and potentially clogging lines or impairing foam performance. Occasional circulation keeps the material suspended, maintains a uniform mixture, and ensures the foam concentrate can be used effectively when needed. Heating, shaking, or filtering don’t address the tendency of the powder to settle and cake in storage, so circulating is the best way to keep it ready for use.
