During drying, paddy grain will loose weight due to loss of moisture: W i = Initial weight [g] W f = Final weight [g] Example: 1000 kg of paddy is harvested at 25% MC, and dried down to 14% MC, what is the final weight of the dried grain? Final weight of grain = 1000* (100-25)/ (100-14) = 872 kg of paddy at 14 % MC.
