How do you dry grain?


Natural air drying is the preferred — and most cost-effective — method of drying grain.

The strength of your fans, however, determines your success, as do environmental conditions.

A higher airflow rate of one to two cubic feet per minute per bushel (cfm/bu) is required to dry most grains

How do farmers dry grain?


Grain drying is process of drying grain to prevent spoilage during storage.

The grain drying described in this article is that which uses fuel- or electric-powered processes

supplementary to natural ones, including swathing/windrowing for drying by ambient air and sunshine.

Why do farmers dry grain before storing it?


Farmers also dry grain for another reason.

Sometimes grain is stored for several months after harvest but before it is sold or used. ... 

Grain like any plant or food has the potential to spoil. If the grain has a high moisture content when it is put into the bin it might develop a mold resulting in crop loss

What is the importance of grain drying?


promotes the development of insects and molds that are harmful to the grain.

lowers the germination rate of rice that is intended for seed.

Therefore, drying of rice is very important to prevent insect infestation and quality deterioration of grain and seed.

 Grain that has changed color because of deterioration.

How much does a grain dryer cost?


The dryer itself may run as high as $100,000.

To know whether you can justify it, divide the total annual cost by the number of bushels per year you plan to dry, advises Minnesota s Wilcke.

That will give you a cost per bushel.

How much does it cost to dry grain?


According to recent Alberta Agriculture surveys, grain drying costs ranged from $45-75/hr, or $10-12/T, or $0.15-0.24/bu.

These costs will vary from year to year as energy costs fluctuate.

The amount of moisture that needs to be dried out of the grain will also affect the total costs.

Why do farmers let corn die?


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. ...

Some of that corn is saved to provide seed for the next season s corn crop.

Why do farmers harvest corn at night?


Corn is harvested at night due to the conditions of the corn stalks.

They are approximately six to eight feet tall, and as the workers are 

harvesting in an area where the temperature can get up to 100°F

during the harvesting season, it is preferable to harvest at night when it is cooler.

What is the importance of drying?


In seed production, moisture content and therefore drying,

often forms a critical component of a seed s quality and potential longevity.

In essence, the drying process is a key step in the supply chain

from paddock to plate for a wide range of commodities.



How can you determine the proper moisture 14 content of rice grain for storing?


Moisture content of grain can be measured by using either:

  1. primary method, based on weight measurements like the (a) oven method or an (b) infrared moisture balance or.
  2. secondary method, using an electronic instrument that uses electrical characteristics of the grains.

What percent moisture should corn be?


The standard moisture for corn is 15.5 percent, so when grain is delivered at greater than 

  1.  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 does a grain dryer work?


Typically a round bin is used that has a perforated floor and a sweep auger.

Heated air is pushed up through the grain while the sweep auger removes grain as

the control system indicates the grain has reached the desired moisture.

Hot grain is moved to a cooling bin when it is discharged from the dryer.

How much does it cost to dry corn per bushel?


Determine the estimated energy cost to dry corn per bushel by multiplying

 the cost per point of moisture removed by the points removed.

The energy cost per bushel to dry corn from 25 percent to 15 percent (10 points) is 

42 cents per bushel (10 points x 4.2 cents per bushel per point of moisture).

What is considered dry for canola?


While canola may be graded “dry” at 10% moisture, 8% moisture or less is preferred for long-term storage. 

Dry canola as soon as possible.

If you can t dry tough or damp canola immediately,

aerate continuously and move canola between bins to prevent spoilage.
