How do you shrink a corn?

How much does corn shrink per point of moisture?

Moisture Shrink, Shrink Factor And Total Shrink

For example: Corn with 25% initial moisture and 15.5% after drying has a moisture shrink of 11.24%. Moisture Shrink Factor is determined as: From the example above, water shrink is calculated as 1.18% for each point of moisture removed when the final moisture is 15.5%.

How do you adjust corn yield for moisture?

Follow these steps:

  1. If initial grain moisture is 20%, initial dry matter content is 80% (100 minus 20).
  2. If desired final moisture content is 15%, ending dry matter content is 85% (100 minus 15).
  3. Multiply weight of wet grain by initial percent of dry matter; then divide by desired ending percent dry matter.

Why did my corn shrink?

The handling loss is found by subtracting the water shrink from the total shrink. 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.

What is grain shrink?

Grain Information

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).

Why do farmers let corn dry out?

The fresher the corn, the more sweet it will taste. … Field corn, also sometimes called “cow corn,” stays in the fields until the ears dry because corn is very high in moisture and must be dry to be processed. That is why farmers leave stalks in the field until they are golden brown in the fall.

Why do farmers dry corn?

Corn harvested for grain will typically be stored for several months and sometimes even more than a year before it is either sold or fed to their dairy cattle. In order for it to be stored for these long periods of time, it must be dried in order to prevent spoiling.

Is dry corn heavier than wet corn?

In addition, the dry corn will weigh less so there will be fewer bushels. … Assuming a dry matter loss equal to 1 percent of the wet bushel weight results in 560 fewer pounds of dry corn, leaving 51,816 pounds. At 56 pounds per bushel, the dry volume is now 51,816 / 56 = 925 bushels of number 2 corn.

How much does a bushel of corn weigh at 20 moisture?

100,000 lbs of grain at 20% moisture = 80,000 lbs of absolute dry matter (i.e., 100,000 x 0.80). 80,000 lbs of absolute dry matter = 94,118 lbs of grain at 15% moisture (i.e., 80,000 / 0.85). 94,118 lbs of grain at 15% moisture = 1681 bu of grain at 15% moisture (i.e., 94,118 / 56).

What is considered dry corn?

The standard moisture for corn is 15.5 percent, so when grain is delivered at greater than 15.5 percent grain moisture, the weight is adjusted down. (This reflects the remaining weight when the grain is dried to 15.5 percent moisture, losing water weight in the process.)

How do you remove moisture from corn?

Start cooling immediately after transferring the corn from the dryer to the storage bin to reduce the condensation potential. To further reduce condensation, cool the corn to about 90 degrees in the dryer before placing it in storage. 10. Remove debris that accumulates during drying.

How is grain moisture calculated?

The most accurate method of determining grain moisture content is the standard scale and oven-based test which uses published standardized procedures to dry a sample in a laboratory oven. The moisture content is then calculated using an equation based on the weight lost during the oven drying.

How many gallons of water must be added per ton of 15.5% moisture corn to bring the total moisture content of the corn up to 30 %?

If corn is too dry, add water to bring the moisture to the proper level. The amount of water required to increase forage moisture content 1% is approximately 5 to 6 gallons per ton of ensiled material.

How do you calculate clay shrinkage?

Math to find shrinkage; (Dry measurement – fired measurement) divided by Dry measurement X 100 = % shrinkage.
