Digester

Term from Paper Production industry explained for recruiters

A Digester is a large, specialized cooking vessel used in paper mills to turn wood chips into pulp for making paper. Think of it like a pressure cooker, but on an industrial scale. It breaks down wood using heat, pressure, and chemicals into a soft, fibrous material called pulp. This is a crucial first step in paper-making, similar to how flour needs to be processed before making bread. When you see this term in resumes, it usually indicates someone has experience with major paper production equipment.
