For the uninterrupted functioning of the drying process through adsorption, it's necessary to have two vessels connected side by side. These vessels are packed with desiccants that serve as the medium for drying. The use of high-efficiency silica gel in heated desiccant dryers, which can endure high temperatures for extended periods, enables the achievement of significantly low pressure dew points.
A vacuum system offers a distinct advantage over other heated drying methods due to its ability to lower the evaporation temperature. In a vacuum, water turns into vapor at a reduced temperature compared to conditions of higher pressure. This reduction in the temperature required for evaporation shortens heating times, making it more energy-efficient and cost-effective.
