Advertisements
Solution
Drying of food grains is a vital protective measure before storing them as food grains contain moisture between 15% and 35%, and for safe storage, the moisture content should be below 14%.
The harvested food grains are dried by spreading them over plastic sheets or on cemented floor. Sun-dried food grains are allowed to cool at room temperature. Commercially, mechanical driers are used for this purpose.
