Grain Production Efficiency

Most grains typically require drying to achieve a moisture content between 8-15% before storage and further processing can take place. Given that grains usually start with a moisture content between 15-32%, the use of grain dryers is essential in any food manufacturing operation involving grains such as corn, wheat, soybean, rice, sorghum, barley, canola, oats, sunflower seeds, and more.

Drying is crucial to ensure safe storage by preventing microbial growth and facilitating production efficiency during subsequent processing stages. Maintaining proper grain moisture levels and storage temperatures is also key to preventing infestations by insects, rodents, birds, and mites to comply with regulatory standards. Bulk grain drying demands significant time and energy investment. Knowing the initial moisture level is vital for accurately determining drying duration and required heat input.

Additionally, monitoring the temperature of stored grain is critical to prevent kernel damage from excessive heat. For example, seed corn in a production facility should not exceed 110-120°F (43-49°C). Higher temperatures are acceptable for livestock feed purposes. Inadequate drying of grains can lead to kernel or seed cracking, fractures, and splitting, causing issues in storage and processing. Stress cracking makes the product susceptible to insect and mold damage, resulting in re-work, increased labor, energy consumption, product loss, and customer as well as regulatory complaints. The primary expenses associated with grain drying before food production include fuel costs (LP or natural gas), electricity, and labor. Moisture content also impacts dust pollution, affecting both occupational health and environmental air quality, necessitating compliance with OSHA, EPA, USEPA  and other air quality regulations.
