Abstract

Est divulgué un système et un procédé d'applicateur de produit destinés à des applications agricoles pour la manipulation et la distribution uniforme de micro-quantités de produits sensibles, tels que des micro-organismes, des produits chimiques, des produits biologiques et/ou des sous-produits. Le procédé consiste à fournir un réservoir de transporteur contenant un transporteur liquide et un réservoir de produit contenant un produit liquide, tous deux reliés par l'intermédiaire d'un chemin d'écoulement de liquide à une sortie d'évacuation. Des quantités de transporteur liquide et de produit sont introduites dans le chemin d'écoulement, et le système règle automatiquement la quantité de transporteur pour maintenir un débit d'évacuation constant. Le système comprend un réservoir de transporteur, un réservoir de produit, une sortie d'évacuation, un chemin d'écoulement de liquide reliant les réservoirs à la sortie, et une dérivation à l'intérieur du chemin d'écoulement. La dérivation régule la quantité de transporteur liquide en fonction du produit introduit, en assurant une distribution uniforme du mélange. Ledit système permet un déploiement en temps opportun et une application constante de produits agricoles sensibles.
