Anyone have this? If you do my question is, can the roller assembly, the rollers that you can remove from the machine, can those be put in the dishwasher, or do you have to hand was the rollers only?

im thinking about selling hot dogs on the side and was wondering how this machine works. how long do the hot dogs typically take to cook? how long can they stay on the rollers? where do you get your hot dogs/rolls/condiments to sell to your customers? any other comments/help would be much appreciated.
