To achieve consistent drying and maintain high food safety standards when using solar dryers, operators should follow these instructions:

  • Pre-Drying Preparation: Complete all sorting, washing, peeling, slicing, or blanching before loading the dryer. Clean all drying trays thoroughly before and after every use.
  • Loading: Spread clean drying nets over the trays and arrange the sliced produce evenly across the racks. Keep the dryer doors tightly closed during operation to prevent heat loss.
  • Post-Drying Care: Allow the dried products to cool completely before packaging them. This step prevents condensation from forming inside the bags, which can cause the food to re-absorb moisture and spoil.
