To achieve the best results in grain drying, it is essential to pay attention to:<\/p>\n<ul>\n<li>The <strong>moisture level of the grain<\/strong> at the time of its harvest. Also, consider that some grains are more sensitive to mechanical and thermal effects. In fact, too high temperatures can cause it to crack or crack on the surface. This can make the grain more susceptible to contamination and spoilage, as well as reduce its commercial value.<\/li>\n<li>The <strong>final destination<\/strong> of the dried product (human food, animal feed, seeding or fermentation). The temperature used for drying must be adjusted to preserve the specific characteristics required for the end use of the grain-human and animal feed-while ensuring a high-quality product.<\/li>\n<\/ul>\n<p>For optimal drying, in order not to expose the grain to excessive thermal shock, it is recommended that an <strong>increasing temperature trend be applied in the initial drying phase<\/strong> and <strong>a decreasing temperature trend be applied before cooling begins<\/strong>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion%E2%80%A6\"><\/span>Conclusion\u2026<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Before <strong>investing in the purchase of a dryer<\/strong> consider two aspects.
