A Solar Dryer System is used to dry food products like fruits, vegetables, grains, and spices using solar energy.

Process:

  1. Loading: Fresh food material is cleaned and placed on drying trays.
  2. Solar Heating: Sunlight heats the air inside the solar collector/dryer.
  3. Hot Air Circulation: The heated air passes over the food material.
  4. Moisture Removal: Heat removes moisture from the food in the form of water vapour.
  5. Air Outlet: Moist air moves out through the ventilation opening.
  6. Drying: The product becomes dry and suitable for storage.
  7. Unloading: After reaching the required dryness, the dried product is removed and packed.

Flow:
Sunlight → Solar Collector → Hot Air → Drying Chamber → Moisture Removal → Dried Product
