Dear all, I am having a dilemma of changing the biological control CCP from 'holding tank' to 'spray dryer'. My argument is that the holding tank temperature won't be able to kill all the microorganisms which the spray dryer could reduce the moisture to <5%, which is the water activity that microorganisms that they couldn't survive. Is it valid for such argument? I could prove that the spray dryer works well.
Btw, I am in a dairy industry.
