Grain Shrinkage Calculator

What is grain shrinkage?

Grain shrinkage is the loss of weight that occurs during the drying and storage of grain. It can be caused by several factors, including moisture loss, insect damage, and mechanical handling.

Grain shrinkage calculation Formula

There are several methods for calculating grain shrinkage, but one common method is as follows:

  1. Weigh a sample of the grain before drying. This is the “wet weight.”
  2. Dry the grain to a constant weight at a specified temperature.
  3. Weigh the dried grain. This is the “dry weight.”
  4. Calculate the shrinkage as a percentage of the wet weight. The formula for this is:

Shrinkage (%) = (wet weight – dry weight) / wet weight x 100

For example, if the wet weight of the grain sample is 1000 grams and the dry weight is 900 grams, the shrinkage would be:

Shrinkage (%) = (1000 – 900) / 1000 x 100 = 10%
