Q. I work on a Shemurah Matza factory and we use a hand metal roller to punch the holes in the flattened dough round pieces. We recently acquired a new one. Does it need Tevila?
What happens if it wasn’t done, does that affect the matzos?
A. Horav Shlomo Miller’ Shlit’a opinion is that since the roller does not touch the food when it is ready to eat,it does require tevila but without a brocho. If that wasn’t done yet, the matzos after the fact can still be used.
See similar ruling on sefer Tevilas Kelim.
