i did the same thing for my engine, used a 1 gallon capacity airtight tupperware style container. I use the color changing desicant beads, they go from orange when new, to dark green when saturated. To my knowledge there is nothing in them that can harm an engine, provided no particles make it through the system into the crankcase. Some of the commercially available ones use similar style desicant. Been using it for 2 years now, no issues that i know of. 1 gallon of desicant will last several months here in humid Ohio.
