I've been wondering if something sitting on top of the beans in the hopper (eg a bag of rice) would stop new oxygen reaching the beans as their level drops. Ideally, the hopper would be cylindrical and the object a simple disk, but mine is the usual conical shape. Or am I over-thinking this?

Maybe just subdividing a little? I was thinking of, like instead of separating out each single dose, separate the bag into 4 day jars, so it's less work on the dividing side but also less oxidation of the beans overall? For you, I think you gotta just try it with the rice and report back. You gonna use a sealed bag on the rice like a ziploc? Or something stretchy but permeable and rely on the rice mass and displacement to slow the air?
