Context & Assumptions

Boiling drying is a vital unit operation for dehydrating high-moisture food slurries by spreading them onto heated surfaces. This model estimates the residence time required for moisture removal while accounting for both the initial sensible heating of the product and the subsequent constant-rate evaporation phase.
