What are the three basic methods of drying?

1. Convective drying: This method involves using a hot gas (like air) to remove moisture from the material. The hot gas transfers heat to the material, evaporating the water. This is the most common method used in industrial settings.

2. Conductive drying: This method relies on direct contact between the material and a heated surface to transfer heat and evaporate moisture. Examples include drying clothes on a heated radiator or using a hot iron to press damp fabric.

3. Radiant drying: This method uses infrared radiation to directly heat the material, causing the moisture to evaporate. This method is often used for drying thin materials like paper or textiles, as it provides a more even and localized heat application compared to convection drying.

These are the three primary methods, but there are many variations within each category. Ultimately, the best drying method depends on the specific material being dried, its properties, and the desired outcome.
