    I've read about large industrial dryers, which don't use heat to dry what's inside, but which use vacuum pumps. The pump sucks all the air out, and the water inside boils away.

    HOWEVER

    I tried to reproduce this by placing a glass of water inside of a vacuum pump, and tuned it on. After 10 minutes, I checked, and the level of water didn't even move a mm.

    Do you know why that didn't happen ? Theoreically, water starts evaporating quickly when placed in a vacuum chamber, right

    Thank you
