High heat drying. Cooking the house. Baking the moisture out. These descriptions all tend to create a fear of the subject of using energy in drying. The fact is that we use energy application in drying every structure that we dry. Unfortunately as a result of overuse or perhaps due to a lack of understanding, heat has been misused as indicated by the first descriptions.
The fact is that an exchange of energy is required for water molecules to go through a phase change. Let’s just say that you have a lot of ice. Perhaps you were in Boston during the record snow storms this winter. The first approach was to shovel and plow the snow out of the way. Unfortunately there was so much snow that eventually there was nowhere to put it. Besides wanting that blasted snow to quit falling, what did Boston need to get rid of all of that snow? They needed some heat energy! When the temperature rose above freezing all that snow started to melt. That’s the phase change from ice to liquid.
