Why do domestic dishwasher cycles take hours instead of being extremely fast like commercial dishwashers?
In: 858
Commercial dishwashers are not dishwashers they are dish sanitizers. They can “wash” very lightly soiled dishes but they are not supposed to and are not designed to clean the dishes. The first step in washing the dishes in a commercial setting is to remove all visible “mess” from the dishes. This may require someone to scrub them with soap and a scouring pad or maybe just a quick rinse with the sprayer. After all the visible mess (food, dirt, ect.) is removed, the soap needs to be rinsed off (this is actually what the sprayer is for), then placed into the “washer” and the cycle started by closing the door. The “washer” uses either heat or a chemical to sanitize the dishes. When the cycle finishes the dishes are removed and should be placed to air dry.
