👉 "Roughdry" is a term used in the field of environmental science and energy efficiency. It refers to a type of drying process that involves using a heat source, such as a fire or a gas, to dry materials. In this context, "roughdry" means that the material being dried has a low surface tension or friction coefficient, which can cause it to become more easily drier than other materials. This process is often used in industrial settings and may be beneficial for reducing the energy
