Methods for flowably dispensing dry powders from a hopper having a dispensing port and a dry powder flow path can include: (a) generating a first non-linear vibration input signal, the first non-linear input signal comprising a plurality of different selected frequencies that correspond to a first dry powder formulation; (b) applying the first non-linear vibration input signal to a dispensing hopper having at least one dispensing port while the first dry powder formulation is flowing therethrough; and (c) dispensing a first meted quantity of the first dry powder through the dispensing port to a receiving member. Related devices and computer program products for dispensing dry powders are also described.
L'invention concerne des procédés de distribution de poudre sèche depuis une trémie à orifice de distribution et trajet d'écoulement de poudre sèche, selon les étapes suivantes: (a) production d'un premier signal d'entrée d'énergie vibratoire non linéaire, qui comprend plusieurs fréquences différentes données correspondant à une première formulation de poudre sèche; (b) application de ce signal à une trémie de distribution ayant au moins un orifice de distribution tandis que la première formulation s'écoule dans la trémie; et (c) distribution d'une première quantité mesurée de poudre sèche via l'orifice, aux fins de réception dans un élément de réception. L'invention concerne également des dispositifs et des programmes informatiques connexes pour la distribution de poudre sèche.
