Abstract

Le problème à résoudre dans le cadre de cette invention concerne un dispositif de désinsectisation à basse température classique qui, à la sortie du matériau traité d’un espace d’entreposage à basse température après une telle opération, entraîne parfois une mise en contact dudit matériau avec l’air ambiant, ce qui provoque une condensation de rosée sur sa surface, le matériau devenant alors humide avec pour résultat une altération de sa qualité. La solution proposée consiste en un dispositif de désinsectisation à basse température comprenant un espace d’entreposage à basse température (11) destiné à stocker un matériau à traiter contenant en son sein des insectes nuisibles ou risquant d’en contenir, une unité de refroidissement (12) qui refroidit l’intérieur dudit espace (11) pour abaisser la température, et une unité de chauffage (13) qui chauffe l’intérieur de l’espace (11). Le dispositif permet de refroidir l’intérieur de l’espace d’entreposage à basse température (11) stockant le matériau à traiter contenant en son sein des insectes nuisibles et de maintenir une basse température pendant une certaine durée à l’aide de l’unité de refroidissement (12). Après son maintien à basse température pendant une certaine durée, l’intérieur de l’espace d’entreposage à basse température (11) stockant le matériau à traiter ou le matériau lui-même est chauffé à une température proche de ou supérieure ou égale à la température de point de rosée de l’air ambiant à l’aide de l’unité de chauffage (13). Les insectes nuisibles que contient le matériau à traiter sont ainsi tués.
