Question Statement:

In automated Clean-in-Place (CIP) systems for dairy sanitary piping, the four synergistic cleaning factors ('TACT' / 4-T) are:

Options:

  • (A) Time, Action (Turbulence/Mechanical shear), Chemical concentration (Titration), and Temperature
  • (B) Torque, Acceleration, Capacity, and Tension
  • (C) Total solids, Acidity, Chlorine, and Texture
  • (D) Thickness, Area, Conductivity, and Transparency

Answer Key:

A

Step-by-Step Solution & Explanation

Sinner's Circle of cleaning efficiency states that cleaning results depend on Time, Mechanical Action (pipe fluid turbulence, $Re > 100000$ or velocity
gt; 1.5\text{ m/s}$), Chemical concentration, and Temperature.
