When we are making our batches of ice cream, we are mindful of the order in which they are made throughout the day to ensure that cross-contamination does not occur. For example, we start the day by making flavors with no allergen issues first (chocolate, vanilla, black raspberry etc.). Next, we do flavors that contain any gluten (cookies & cream, brownie flavors, etc.). Finally, we end each day making the flavors that contain nuts or nut products so these are the last flavors made out of our batch freezer. As we switch flavors the machine is cleaned between flavors and when we finish making ice cream for the day, the ice cream batch freezer is completely disassembled so that proper washing, rinsing, and sanitizing can happen to ensure that it is clean and ready to begin making more ice cream the next day.
