A Combined Solar Tunnel Dryer and Desiccant-Bead Store for Village Seed Saving: Design, Budgets, and Failure Floor
Year: 2026
Type: preprint
Abstract: Design study (SIMULATED, NOT MEASURED) of a combined village seed station: a solar tunnel dryer held to a 40 C seed temperature ceiling dries one tonne of seed from 20% to 12% moisture, then desiccant beads in sealed drums finish drying to 9% and hold it for 180 days, with a solar regeneration loop for the beads. All budgets are computed by the deposited script. The station fails below an insolation floor of 3.74 kWh/m2/day.
