Solar dryer

Traditional methods of food drying is to place the foodstuffs in the sun in the open air This method called sun drying is effective for small amounts of food The area needed for sun drying expands with food quantity and since the food is placed in the open air it is easily contaminated Therefore one major reason why sun drying is not easily performed with larger quantities of food is

Generally farmers dry their agricultural products and food stuffs in open sun In open sun drying the products were sprayed under sun and moisture evaporates from it This open sun drying is having so many drawbacks such as dust contamination insect contagion microbial attack Decadence due to rain etc To overcome these drawbacks the new technology emerged in market is Solar Air Dryer

In comparison to the conventional method of open sun drying the designed solar dryers enhanced both the drying rate and the overall quality of the final product In the designed solar dryer over three days of consecutive drying (30 h of drying) the moisture content of tomato wedges was reduced from 19 to less than 1 kg [H2O] kg−1 [dry matter]
