Solar Fish Dryer for Seafood Processing | Rudra Solar Energy Project

Seafood drying involves a high-moisture raw material and requires careful control of product loading, airflow and drying conditions. For this project, Rudra Solar Energy planned a solar fish dryer system for seafood processing where the client required a defined, enclosed drying setup instead of relying only on direct open-sun exposure. The project was approached from the perspective of moisture removal and batch management. Fish and other suitable seafood products can differ considerably in size, preparation, thickness and initial moisture, so drying performance cannot be based on one fixed time or temperature. An enclosed tray-based solar drying system helps create a more organised drying environment while reducing direct exposure to dust, insects and outdoor handling conditions. ICAR-CIFT also documents solar and hybrid dryers specifically for hygienic fish drying, including backup-assisted configurations for unfavourable weather conditions. The system configuration was therefore planned according to the seafood-processing requirement, tray spreading area, loading quantity, airflow requirement and expected operating conditions.
