Calculating Grain Weight Shrinkage in Corn Due to ...

shrinkage occurs, due to water loss alone, if the 1,000 lb. of grain is dried to 15.5% moisture? We can calculate it. The dried corn still contains 750 lb. of dry matter, but now the dry matter is 84.5% (100% minus 15.5%) of the total weight. Therefore, the total weight of the dried grain is 750 lb. divided by 0.845, or 887.57 lb.

Grain Shrinkage Calculator - Alberta

Shrinkage occurs whenever wet grain is dried. As grain is dried, moisture is removed from the grain by evaporation, which results in a loss of volume (fewer bushels) and a weight loss (fewer lbs or tonnes of grain). This calculator may be used with any type of grain including wheat, barley, corn beans sunflowers, canola and flax.

How To Calculate Corn Moisture Shrink - No-Till Farmer

Oct 29, 2014  When shelled corn is dried from 25% to 15.5% total weight reduction is 11.24% of the original weight. When handling loss is added the total weight reduction would be greater than 11.24%. To estimate the total shrink or total weight loss grain buyers generally use a constant shrink factor, which can range from 1.2% to 1.5%.

Weight loss during drying. 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.

Understanding Corn Shrink. - Farms

Oct 20, 2014  Corn shrink occurs whether the grain is stored on-farm or at a commercial facility. Shrink is a reduction of grain weight (mass) and results when corn is dried to a moisture content that is safe for storage. When corn buyers apply a constant shrink factor to estimate shrink (e.g. 1.4), they are accounting for moisture and handling losses.
