Washing Dishes in Mineral Water?

This may sound like the bottled water craze had gone too far, but hold on, this might not be as inane as it sounds.  This is an innovation featured in the new Siemens speedMatic dishwasher designed to make the drying cycle faster and more efficient by heating up faster than regular H2O.

According to Greenlaunches.com, Siemens have come up with an environment friendly and green zeolitic drying system that has won the Award for Climate Protection and the Environment. Together with the Siemens speedMatic dishwasher, the system is around 20% more efficient than others in the highest energy-efficient category. It uses just 10 liters of mineral water instead of 14 liters per cycle and this technology will now be mass produced. The technology will also find its place in mid-range models and not just high-end ones. Minerals that generate supplementary heat that help shorten the program to less than two hours at 50 degrees Celsius makes it more efficient than other dishwashers around.

This heat is supplied by zeolites that are aluminosilicate minerals with a very large surface area and microporous structure. They absorb 40% of their dry weight in water and give of heat and also the absorbed water.  Conversely, they release the water they stored when they were heated. During the drying cycle, the warm, moist air is channeled into a container under the dishwasher interior space, where there are 1.15 kilograms of zeolites. The mineral absorbs the moisture and releases hot, dry air, making the drying cycle much faster. In the next washing cycle the minerals are regenerated when the moisture is removed from them as the dishwasher is heated up.

At 50 degrees Celsius, for example, the standard program is reduced to just under two hours, about 30 minutes less than is needed by conventional dishwashers. The speedMatic is thus the fastest dishwasher in the AAA (highest-efficiency) class. And thanks to its energySave function, the machine consumes about 20 percent less electricity than the previous best dishwasher in its class. Further attractive features are higher spray pressure for hard-to-clean pots and a clever device for improved dissolution of dishwasher tabs.  And for maximum hygiene, like the level required for baby bottles and cutting boards, the speedMatic’s rinse temperature can be set at over 70 degrees Celsius, which will kill 99.99 percent of all bacteria and germs.
