🍫 Cocoa Bean Sun Drying: Fickian Moisture Diffusion and Drying Time (2D)

Cross-section of fermented cocoa beans drying on a sunny terrace. Set bean half-thickness, air temperature, solar heating and relative humidity, and watch moisture leave the bean through the day and night. The moisture-ratio curve, the Arrhenius diffusivity and the time to reach the storage moisture come from Fick diffusion in a slab, with four in-page numerical checks. A food-physics companion to the 3D cocoa-processing courtyard.
