A dishwasher mixes a weaker chlorine solution in the 25 to 49 mg/L range. What minimum water temperature does the Food Code set for it?
a.120°F, regardless of whether the pH is 8 or 10
b.100°F, because the solution is below 50 mg/L
c.75°F, the same as a quaternary ammonium solution
d.55°F, the same as a 100 mg/L chlorine solution
解析
The chlorine chart pairs weaker solutions with hotter water: 25 to 49 mg/L needs at least 120°F at either pH, 50 to 99 mg/L needs 100°F at pH 10 or less and 75°F at pH 8 or less, and 100 mg/L needs only 55°F. The less chlorine there is, the more heat the solution needs to do the same work.
