Dit vergroot het risico op broei en kwaliteitsverlies.<\/p>\n<p>De beluchtingsspeer van Jansen en Heuning is ontwikkeld om dit snel en gericht te verhelpen. De speer brengt koudere lucht in het graan en kan bij broei precies in de kern van de broeiplek worden geplaatst.<\/p>\n<p>De speer is eenvoudig inzetbaar als zelfstandig hulpmiddel voor koelen en drogen. Door de combinatie van gebruiksgemak en technische capaciteit is deze geschikt voor toepassing in loodsen en silo\u2019s.<\/p>\n<h2 data-start=\"955\" data-end=\"1246\">Hoe werkt de beluchtingsspeer<\/h2>\n<p>In de onderstaande video wordt getoond hoe men de speer in het graan brengt.<\/p>\n<p data-start=\"955\" data-end=\"1246\"><iframe src=\"https:\/\/www.youtube.com\/embed\/nU_hmZMuQNk\" width=\"560\" height=\"315\" frameborder=\"0\" data-mce-fragment=\"1\"><\/iframe><\/p>\n<h3 data-start=\"1248\" data-end=\"1578\"><strong data-start=\"1248\" data-end=\"1287\">Testresultaten uit een Deens onderzoek<\/strong><\/h3>\n<ul>\n<li>Koelt circa 100\u202fton graan per positie<\/li>\n<li>Op 3\u202fm afstand nog 30\u202fm\u00b3\/luchtdoorvoer per uur per m\u00b2 oppervlak<\/li>\n<li>In een silo van 7,5\u202fm daalde de temperatuur binnen 22\u202fuur van 18\u202f\u00b0C naar 17\u202f\u00b0C in de bovenlaag en van 28\u202f\u00b0C naar 20\u202f\u00b0C onderin.\n<p>In de presentatie hieronder ziet u hoe de warme lucht wordt verdreven<\/li>\n<\/ul>\n<p><iframe src=\"https:\/\/www.youtube.com\/embed\/_8dAjRwwWz8\" width=\"560\" height=\"315\" frameborder=\"0\"><\/iframe><\/p>\n<h2 data-start=\"1900\" data-end=\"1935\">Waarom deze beluchtingsspeer?<\/h2>\n<ul>\n<li data-start=\"1939\" data-end=\"2033\">Gericht te gebruiken in kritische zones waar vocht en temperatuur boven de veilige norm zijn<\/li>\n<li data-start=\"2036\" data-end=\"2114\">Verhoogt de effectiviteit bij bewaring van graan en voorkomt kwaliteitsverlies<\/li>\n<li data-start=\"2117\" data-end=\"2210\">Te gebruiken naast of zonder een bestaande beluchtingsinstallatie<\/li>\n<li data-start=\"2117\" data-end=\"2210\">Eenvoudig systeem, wat niet voorafgaand aan het storten van het graan hoeft te worden ge\u00efnstalleerd<\/li>\n<li data-start=\"2213\" data-end=\"2291\">Technisch op niveau dankzij gecontroleerde luchtstroom en een solide performance<\/li>\n<\/ul>\n<h3 data-start=\"1580\" data-end=\"1893\"><strong data-start=\"1580\" data-end=\"1598\">Specificaties beluchtingsspeer\u00a0<\/strong><\/h3>\n<ul>\n<li>Ventilator 1,1\u202fkW, 2.800\u202fRPM \u2013 luchtcapaciteit 1.500\u20131.700\u202fm\u00b3\/uur<\/li>\n<li>Perforatie 1,5\u202fmm<\/li>\n<li>Compleet geleverd met boorhulpmiddelen \u2013 optioneel met kabel en stekker<\/li>\n<li>Gewicht 23,9\u202fkg<\/li>\n<li>Standaard lengte 2\u202fm<\/li>\n<\/ul>\n<h3 data-start=\"1871\" data-end=\"1968\"><strong data-start=\"1871\" data-end=\"1882\">Contact <\/strong><\/h3>\n<p data-start=\"1871\" data-end=\"1968\"><span style=\"font-size: 16px;\">Heeft u vragen over graanbeluchting in uw opslag?
