Research Article Geometry-aware Analysis of Wheat Grain Hydration Prior to Milling
Keywords:
Grain, grain moisture,, grain characteristics, computer modeling, hydration kinetics, conditioning, diffusion modelsAbstract
This study analyzes geometry and short-time hydration of two wheat varieties from Uzbekistan, “Asr” and “Alekseevich.” Grain dimensions were measured by digital caliper, microstructure examined microscopically, and surface/volume reconstructed from 3D scans. Hydration kinetics were recorded gravimetrically at 5-min intervals for 30 min under 20–25 °C and 40–50 °C. “Asr” grains were larger and showed faster water uptake, with higher mass gain than “Alekseevich.” An ellipsoidal multi-layer diffusion model confirmed geometry-dependent moisture penetration. Results indicate that geometry-aware conditioning enhances millability and flour quality while minimizing repeated wetting–drying cycles.
