Comment on Why don't we have cool vending machines in the US?
fine_sandy_bottom@lemmy.federate.cc 4 days agoI don’t understand the question.
You have a vending machine in a train station cooking greasy popcorn all day. Is there a machine that can clean that ?
Baked on greasy-buttery-ness is very difficult to clean.

Pretty sure a machine that can be built to make popcorn can also.be engineered to self clean. Human maintenance one per week to swap out parts and re-top corn.

I’m sure it’s possible but I suspect it’s simply not cost effective.
Removing grease requires hot water, harsh solvents, and scrubbing. If you’ve ever cleaned an oven or bbq or whatever I’m sure you’d agree that it would be very difficult to automate.
