Früchte trocknen mit Ionenwind

Der Ventilator hat ausgediehnt

(PresseBox) (Dübendorf, )
Nach der sommerlichen Ernte gelangen Früchte als Trockenobst saisongerecht in den Verkauf. Wird Obst oder Gemüse durch Wärme getrocknet, können jedoch Nährstoffe zerstört werden und Aromastoffe verloren gehen. Deshalb ist das nichtthermische Trocknen von Lebensmitteln – also ohne Erwärmen –, in der Industrie besonders beliebt. Dabei kommen unter anderem Ventilatoren zum Einsatz. Ein neues, an der Empa entwickeltes Trocknungsverfahren mittels Ionenwind verspricht nun ein energieeffizienteres, schnelleres und erst noch schonenderes Trocknen von Lebensmitteln.

Wenn sich die Rotorblätter eines Ventilators drehen, entsteht ein gleichmässiger Wind. Dieses Phänomen kennt man aus dem Alltag, und so nutzen wir den Ventilator an heissen Sommertagen, ym bgw Vnxdbctzs ea tfhczaransh.
