The Latest Grain Drying Techniques for Modern Farming

Grain drying techniques have been catapulted into the modern era over the last few decades. With the influx of technological advancements, where farmers used to rely on the prevailing weather conditions, they can now rely on remote digital technology to assist with the grain drying process.

In this article, we’ll share why you should invest in modern grain drying techniques, plus three of the leading techniques farmers are using.

Why Invest In Modern Grain Drying Techniques

Farmers can reap a variety of benefits by investing in modern grain drying techniques. These techniques can help improve the efficiency, speed, and accuracy of their operations. Modern grain drying will also deliver multiple advantages ranging from improved grain quality and yield to cost savings and increased agricultural competitiveness.

When farmers upgrade from traditional techniques to more modern equivalents they typically see a dramatic increase in speed, efficiency, and accuracy. That, in turn, means a faster and more consistent drying process that not only can be relied on to deliver results but also reduces energy costs and produces considerably less waste.

Alongside the process itself, the product sees benefits too. Both grain quality and overall yield see substantial improvements. This is, in part, because farmers can avoid grain damage during the drying process, maintain grain quality, and ultimately increase their overall yield by using advanced equipment and technologies.

There’s no hiding from the fact that the agricultural industry is constantly changing, and so are market demands. Farmers can stay ahead of the curve and remain competitive in the industry by investing in modern grain drying techniques that meet changing demands.

Grain drying is certainly not a modern technique, but the advancement in technology and understanding has created opportunities to improve and modernize the old ways. For example, it was a regular occurrence that drying grain in large bins would produce hot spots. These hot spots would lead to negative effects such as rot and germination. By using modern grain management techniques such as heat and moisture probes, heat and moisture spots can be detected before they cause any major issues.

Modern Grain Drying Techniques

The following three techniques are the most popular grain drying techniques currently in use in modern farming. Each is part of a rapidly evolving technological field, so we’d recommend regularly checking for developments.

Natural Air Drying

Natural air drying is a straightforward, low-cost method of drying grain that entails spreading the grain out in thin layers and allowing it to dry naturally in the open air. Using the ambient temperature and natural airflow, this process evaporates moisture from the grain, reducing its moisture content to an acceptable level for storage or further processing. Natural air drying is commonly performed on large open areas such as fields, storage yards, or drying platforms, and can take anywhere from a few days to several weeks, depending on the weather and the desired final moisture content.

This is one of the oldest and most traditional grain drying methods, and it is still widely used in many parts of the world today. So, you’d be forgiven for questioning why natural air drying is featured on this list. While it is not considered a "modern" technique in the sense of employing cutting-edge technology, it is still relevant and widely used in the agricultural industry.

Natural air drying can, however, be improved and optimized with modern techniques and technologies, such as improved airflow management and moisture monitoring. These modern additions increase the drying process's speed, efficiency, and accuracy. So, while it is not a modern technique in and of itself, it can certainly benefit from modern innovations.

While natural air drying is a simple and low-cost method of drying grain, it can be further optimized through the use of modern techniques and technologies. Improved airflow management and ventilation can dramatically speed up and improve the efficiency of the drying process. This lowers the risk of spoilage or insect damage. When combined with moisture monitoring systems, farmers receive real-time data on grain moisture content, allowing them to make informed decisions about when to harvest or store grain.

Batch Drying

Batch drying is a type of drying grain that involves placing grain in a dryer and drying it to a specified moisture content in a single cycle. This method is commonly used when drying small amounts of grain, different varieties, or different grades of grain that require different drying parameters. The batch drying process allows for precise control of drying conditions. That means greater control over temperature, airflow, and moisture level, delivering more flexible and efficient drying of various grain types.

The batch drying process is a step up from a natural air drying process. The precise control that farmers have over the drying process produces far more effective results, higher-quality grain, and a better financial yield. It is, however, a considerable investment both in initial costs and then ongoing maintenance and operational costs. Typically, farmers do see their investment returned within a matter of a few harvests, so technology should be seen as a long-term investment rather than a quick fix.

The most advanced technologies allow for real-time monitoring systems that track moisture content to a precise level. That means there are considerably reduced chances of over or under-drying happening. As technology has evolved so have the energy efficiency and emission rates for the equipment, further reducing costs and environmental impact. More and more grain storage bins are incorporating built-in batch dryers plus there are many portable batch dryers on the market. These can provide farmers with greater flexibility and convenience by allowing them to dry grain on-site without the need for transport or additional handling.

Continuous Flow Drying

Continuous flow drying is a drying process where grain is fed into a dryer on a continuous basis, typically via a conveyor or auger. The grain is then dried as it moves through the machine. It is commonly used for large-scale grain drying as high volumes can be processed rapidly while also reducing the need for manual grain handling and transfer. Because the grain is dried in a controlled and continuous process, continuous flow drying is typically faster and more efficient than other drying methods such as batch drying or natural air drying.

When a continuous flow drying process is used the grain is dried in a more controlled manner that typically results in more uniform moisture content in the dried grain. That said, there are some drawbacks to consider. The high capital and operational costs certainly can't be ignored, these are industrial-scale operations with a cost to match. There is also a higher requirement for specialized equipment and infrastructure once the initial dryer is in place. Advancements have been made to combat energy use and emissions but continuous flow drying is still more energy-intensive and environmentally damaging than other drying methods.

Key Takeaways

The various grain drying techniques that are available to farmers are certainly evolving as time progresses. We’re certainly in a time of technological advancement, the modern farmer should be ready to embrace these improvements, or risk being left behind.

Even though natural air drying is an old technique, there is modern equipment that can dramatically improve the efficiency and effectiveness of the process.
Batch drying is one of the most popular grain drying techniques, and often can be completed on-site.
Continuous flow drying, while incredibly effective, requires a large-scale operation.
