Abstract: ABSTRACT A System and Method for Adaptive Multi-Zone Solar Drying Using Active Moisture-Response Interrogation and Reversible Airflow Control The present disclosure relates to a system and method for adaptive control of multi-zone solar drying of agricultural produce. The system comprises: a plurality of distributed environmental sensors, a plurality of product surface temperature sensors, a plurality of airflow and differential pressure sensors, a plurality of weighing assemblies, a reversible airflow assembly, a plurality of controllable vents, a heating unit, and a processor. The processor induces a controlled perturbation in the airflow and measures the resulting humidity, temperature, pressure, airflow and weight responses to assess internal moisture migration. Independent calculations of air side moisture removal and weight based moisture loss rates are reconciled to identify uneven drying, case hardening, condensation risk, leakage, sensor drift, actuator failure and false completion conditions. In response, the processor selectively controls airflow direction, fan speed, ventilation, recirculation and heat input. The drying is terminated when moisture-removal, spatial-uniformity, transient-response, measurement-confidence, and safety criteria are all concurrently satisfied, improving endpoint reliability, drying uniformity, product protection, energy utilization, and retrofit operation under variable environmental conditions while maintaining protected local operation during intermittent communication failures.
