When I was making my way through college I spent a few years washing dishes at a local diner. I was amazed at the industrial dishwasher we had. With a lip resting on a sink, you filled a small box cart, put them into the device, pulled the handle down, and after ~1 minute the machine stopped, you pull the handle up, and push the cart through to the other side where the dishes sit drying. The water was so hot that it dried amazingly fast.
Even better, I prefer to hand-scrub my dishes, but would love something like this just to give them a quick, sanitary rinse. It doesn’t have to be super-heated - just tap water hot would be fine.
Part of the amazing drying time is due to the chemicals used by commercial dish washers. Most utilize a rinse agent that lowers the surface tension of the water, causing it to sheet off the dishes during the final rinse. This makes the droplets of water run off, as opposed to remaining on the surface of the dishes to be set’set’ by the heat of the drying cycle, forming spots and film.
This is also helpful in obtaining dry dishware via air drying.
A home use commercial unit would be pretty pricey, as well as the chemicals it uses. If you’re looking for a fairly cost effective sanitizing solution for hand washing that’s not temperature dependent, there are many iodine based products for the rinse water available.
I have one of those at my firehouse hall, not the pass through ones, but a commercial DW that runs the same way.
It uses no detergent or rinse, just water. There are ones that use detergent and/or rinse agents, at the time that we looked they cost less but require the additional consumables.
It takes a long time to be ready to run it’s first load once started, it needs that time to heat up the water. The water’s ‘clarity’ is monitored, and if it gets too dirty it is exchanged for clean water, and there is a delay when that exchange happens. If the water cools too much, again a delay as the water is heated. This delay does not happen often however, but it does sometimes happen.
I believe the wash cycle complete is about minute, so once it gets going it goes very fast and can get practically 5 or so ‘single shelf’ loads every 10 minutes - allowing for exchanging the dish ‘shelves’
Size is about the same as a household DW, I expect it may fit the conventional space for a DW.
IIRC it cost $5000.
Due to the cost and the initial heat up time I don’t see it practical for household use.
