B17 and other powder coating strippers must be stored in an HDPE container with a lid. I suggest a container that is as big as your oven (if you are using a household oven or smaller). Since you cannot powder coat things larger than your oven, there is no reason to have a stripping tank larger than your oven. If you do have a large oven, I suggest a stripping tank that accommodates your biggest, most-frequently coated item.

This will work, it is just more labor intensive and takes longer.
