Drying
Drying is a crucial industrial process where moisture or liquid is removed from materials to make them suitable for use, storage, or further processing. This is similar to how a clothes dryer works, but on an industrial scale. Chemical engineers use various drying methods depending on what's being dried - it could be anything from food products to pharmaceuticals to chemicals. Understanding drying processes is important because incorrect drying can damage products, waste energy, or create safety hazards. When you see this term in resumes, it usually refers to experience with industrial drying equipment and processes.
