Zeolith drying
Have such a system in my DW running here right now.
This technology is 100% not anything you guys are thinking.
Far smarter, far more efficent, far better at drying.
Been over here for what has to be a decade already...
Zeolith is a mineral with a huge surface area.
Like, insanely huge.
Incredibly porous that stuff.
At the begining of a dry cycle, dishes are allowed to drip dry and to saturate the air with moisture for about 5 minutes.
Then the fan starts and blows the air through the mineral back into the dishwasher interior.
The moisture condenses onto the mineral.
Because of the huge surface area, water condenses onto the mineral even if the mineral gets pretty warm.
When ever moisture condenses a lot of energy gets transfered.
Like, a lot.
That's the reason why steam scalds so quickly.
That heat is taken away from the mineral by the moving air that is now dry.
Rinse repeat from there on basicly.
While heat transfer is pretty efficent, the temperature won't increase much if even any.
Now the mineral is wet once the cycle ended.
And here is where it gets really genius.
There is a heater embeded in the mineral container.
At the beginning of the next wash cycle, the fan and that heater are engaged while the prerinse is running.
The water evaporates from the mineral and is condensed back into the wash water.
Thus, the heat used to dry the mineral is used to up the wash temp.
Basicly, it is just recycling the energy.
The heating power for that heater is something like 200W or so if I am not mistaken (I think I read somewhere that it's 30 Ohms at 50V).
Bashing technology before knowing anything about it, I thought we all learned what prejudice yields smh...
