Ethanol Distiller drops tiny packets of polluted dirt

The "ethanol distiller" doesn't store any polluted dirt internally, so it's constantly dropping tiny amounts of polluted dirt on the ground, every second. It should probably store and then drop in 10kg increments, like the water sieve, etc. Save attached in case you'd like to see an endless parade of dupes picking up tiny amounts of dirt.
