WebJan 2, 2024 · The Drying Curve When engineers refer to the design of a drying process or drying equipment, there is nothing more important or more challenging to obtain than the drying curve, the graphical representation of how a determined product will dry over time, under certain conditions. Following are stages of the drying curve. WebJun 6, 2024 · A drying curve test should include at least three constant inlet temperatures that are below any temperature limitation — except perhaps for products that require a phase change or dehydration. In each test, the inlet conditions (temperature, flow, humidity and pressure) should remain constant.
