Traditional sun drying methods under open sun for
preserving low value fishery as well as agricultural
products have several disadvantages such as
contamination of food products by dust, dirt, birds,
animals and insects and spoilage due to rain |
| Bad Practices: |
|
| Suggestions Given: |
|
| To overcome the disadvantage of
open sun drying, a solar dryer with alternate
energy backup of electricity was designed and
developed for drying fishes and fish products
hygienically in hot and humid climatic conditions.
