Does accumulating dough in the freezer create a shiur for separating challah?

Does accumulating dough in the freezer create a shiur for separating challah?

One of the rules of hafrashas challah is that if different batches of dough are placed in the same bowl, even if each individual portion is less than the shiur (requisite amount) for separating challah, hasal metzarfan (the ‘basket’ [or receptacle] combines them) into one large dough;by virtue of the fact that they are in the same bowl, challah must now be separated. A tanur (oven), on the other hand, does not combine the batches of dough placed inside it; if each batch placed in the oven is less than the shiur, they remain exempt from challah.

A related, oft-asked question is whether storing different batches of dough, or even baked goods,  in a fridge or freezer—whether for mishloach manos, for Shabbos, or for whatever reason—would serve to halachically combine those batches of dough in the manner described above. The common custom is that different batches of dough in the same freezer are not considered cumulative for separating challah. There are a number of reasons to justify this practice: the fridge and freezer are mechubar l’karka (connected to the ground by virtue of being plugged in); the portions of dough weren’t placed there with the intention to combine them; they’re in separate bags, and many other reasons. Although each of these factors on its own is not sufficient, these factors collectively serve to exempt the dough from becoming obligated in challah. #503
