I'm currently setting up a brewery and have been sorting through the equipment that was purchased for this brew pub before I came on-board. In doing so, I've only identified a single-vessel CIP system (with 80L tank & skid-mounted pump) for cleaning, rather than a double-vessel CIP system, which is what I've always used (one for acid rinsing & one for caustic cleaning solutions). To my knowledge, caustic solutions are more beneficial at 70?. That being said, what's most optimal for this type of setup? Is using a cold caustic solution acceptable and, if so, should I increase both the time and concentration of the caustic for this process? Alternatively, should I purchase an additional tank equipped with temperature control (including a heating element) for caustic use only?
