What is the purpose of maintaining low vapor pressure in drying?

Maintaining low vapor pressure is essential in the drying process because it creates an environment where moisture can escape more readily from the materials being dried. When the vapor pressure in the room is low, the moisture present in the wet surfaces has a greater driving force to evaporate into the air. This helps to speed up the overall drying process, allowing for more efficient evaporation of water from the affected materials.

In drying applications, it's critical to enhance this moisture removal to achieve optimal drying conditions, hence effectively lowering the humidity and vapor pressure supports the goal of expediting the drying process. In contrast, higher vapor pressure would hinder evaporation, prolonging the drying duration and potentially leading to more extensive damage or mold growth.
