As a result, heat can build up in certain zones and increase the risk of spoilage. The aeration spear by Jansen&amp;Heuning is specifically designed to address this quickly and effectively. The spear can be used as a complementary tool alongside existing aeration systems, but also functions as a stand-alone solution for cooling and drying grain. It combines practical usability with solid technical performance and is suitable for use in both silos and flat storage.<\/p>\n<h2 data-start=\"881\" data-end=\"922\"><strong data-start=\"885\" data-end=\"922\">How does the aeration spear work?<\/strong><\/h2>\n<p data-start=\"924\" data-end=\"1008\">The video below provides a visual explanation of how the spear operates in practice.<\/p>\n<p><iframe src=\"https:\/\/www.youtube.com\/embed\/nU_hmZMuQNk\" width=\"560\" height=\"315\" frameborder=\"0\"><\/iframe><\/p>\n<h3 data-start=\"1015\" data-end=\"1076\"><strong data-start=\"1019\" data-end=\"1076\">Test results from official Danish research institute<\/strong><\/h3>\n<ul>\n<li data-start=\"1080\" data-end=\"1149\">The spear can cool approximately 100 tons of grain per position<\/li>\n<li data-start=\"1152\" data-end=\"1240\">At a distance of 3 metres, the aeration level remains 30 m\u00b3 of air per hour per m\u00b2<\/li>\n<li data-start=\"1243\" data-end=\"1484\">In a silo of 7.5 metres high, it was shown that after 22 hours the temperature dropped from 18\u202f\u00b0C to 17\u202f\u00b0C at the top, and from 28\u202f\u00b0C to 20\u202f\u00b0C at the bottom.
