Dissolved water is water that has been dissolved into the oil. Think of humidity, which is the measure of the amount of water dissolved in
the air, or of sugar being dissolved into tea. As the temperature of the air or tea rises, the capacity for more dissolved water or sugar
increases. With dissolved water the visual appearance of the oil looks hazy.
Similarly, when the temperature of oil rises, the capacity to absorb water rises, but to a point. Any extra water cannot be dissolved and
is free floating with the oil. We then call this water free water. After all free and emulsified water is removed, the vacuum dehydrator
then focuses solely on dissolved water. By this time, the vast majority of water in the system has already been removed. Removing dissolved
water is a slower process.
