This study created a mathematical model to simulate softgel drying rates and determine optimal drying conditions. The model divides the softgel into nodes and uses Fick's law of diffusion and mass transfer equations to calculate water concentration and temperature changes over time based on humidity, air velocity, and temperature. Simulation results showed that drying is optimized at low relative humidity (<50%) and low air velocity to allow water to leave the gelatin surface while avoiding case hardening. The model can help determine conditions that yield the proper final fill and shell moisture for good capsule quality without extensive experimentation.
