Grain moisture levels are important. Too much moisture and grains can become damaged, too little and they can have their value reduced. With so much riding on getting the moisture level of grain right, it's no wonder that many farmers utilize aeration systems for their grain bins. Though aeration systems are popular, many farmers still have questions about how they work and if there are any disadvantages to using a grain bin aeration system.

At Avonlea Farm Sales Ltd, we understand that protecting harvested grains during storage is important to farmers. That’s why we are proud to offer a variety of grain bin storage options and grain bin monitoring systems that help farmers protect their investment. We also know that aeration fans can play an important role in achieving and maintaining optimal moisture levels. In this post, we help answer some common questions about grain bin aeration fans and help you feel more confident when choosing an aeration system for your grain storage.

How Do Aeration Fans Work?

Grain bin aeration systems play an important role in maintaining the quality and longevity of stored grains. These systems work by circulating air through stored grain, controlling temperature and moisture levels. Aeration bins typically consist of a network of ducts installed beneath or above the grain surface. The process begins by pulling ambient air through ventilation fans, which are strategically placed to create a uniform airflow pattern. The air is then directed into the ducts, allowing it to permeate through the grain. As the air passes through, it absorbs excess moisture and removes heat, preventing spoilage, insect infestation, and mold growth.

Do Aeration Fans Blow Air into a Bin?

Some farmers wonder about how aeration systems function. From time to time, we have been asked, do aeration fans blow air into a bin? Though some aeration fan systems may function differently than others, most function by blowing air into the grain bin rather than pulling moisture out of the bin. Some aeration systems may utilize fans that pull moisture out of a grain bin. However, this is not the most common choice.

Are Temperature Monitors Needed When Using Aeration Fans?

Aeration fans can make managing grain moisture levels easier. However, it is important to note that a grain moisture monitoring system should still be considered. In some instances, aeration fans can put too much or too little air into a bin. If unmonitored, this can lead to issues with grain quality. Utilizing a grain bin monitoring system can help farmers stay in control of grain moisture levels and use aeration fans effectively.

Aeration fans are fantastic tools that farmers may wish to use when looking to optimize the moisture levels of stored grains. Although they are not a set-it-and-forget-it tool, they can make the management of grain storage easier.
