Grain stores are an integral part of the infrastructure of a farm. It is therefore essential to make sure that the right products are used to construct bins and the right management techniques are used to ensure that grains stay in good condition. Drying grains before they are stored is just as important as monitoring their moisture content after they are stored. Grains can also be dried after they are stored in bins.
At the beginning of planting season, most farmers concentrate on planting crops. However, they should not fail to monitor the produce they have stored. This applies especially to people who have stored corn that has moisture content of 16 percent or higher. Through grain bin monitoring, farmers can keep stored produce in the best condition.
One way to monitor stored produce is to sample the cereals to see if they are spoilt and check their moisture content. Farmers should check if the produce at the surface of bins as well as the produce that is six feet deep is spoilt. They cause utilize a grain probe to check the produce in the deeper layers of a bin. If the relative humidity in bins is less then seventy five percent and ambient temperatures average at about forty to sixty degrees Fahrenheit, the fans should be left to run continuously.
Farmers who look forward to storing their produce through the summer months should avoid warming their produce at a temperature that is higher than sixty degrees Fahrenheit. They should also ventilate the headspaces of their bins at night so make sure that seed that is on the surface does not condense. Condensation can cause grains to get spoilt or crusted. Cooling cereals down is essential because it helps prevent condensation.
The main thing that causes stored grains to go out of condition is failing to control temperatures. Grains are good insulator and they therefore do not cool in a uniform manner when the temperatures outside a bin drop. Air close to the walls of bins cools and settles towards the bottom of the bins to create convection currents.
The cool air the rises through the warm grain. During this process, the stored produce absorbs moisture in the form of water vapor. It continues to move towards the cooler grain that is closer to the surface. The moisture then condenses making the produce to get spoilt. To monitor temperature effectively, you can turn the stored produce or aerate the bins regularly.
If the produce is stored with a moisture content that is above grade requirements, it can create an environment that is conducive to fungal growth and insect infestation. In order to determine the moisture content of stored produce, you should take samples from bins every three to four weeks after storage, if the produce is not aerated or turned. Take samples from a number of areas of the bulk and keep them in a sealed plastic container before testing.
As farmers think about drying or aerating their produce, they should also think about the physical characteristics if the grains. Some factors like grain class affect the static pressure and in turn, this affects the fan requirements for effective aeration. Typically, as static pressure rises, the time required to effectively aerate grains also changes. Farmers can seek advice from the suppliers who sold the aeration system to them to know the amount of time it takes to aerate or dry the produce they have stored.
