Patent ID: 7407345

Claim:
A method for distributing a fluidizable powder material with assistance of gravity from a reservoir to a plurality of individual material receiving units through separate outlets arranged in at least one fluidizable conveying device, a first of the plurality of material receiving units being located upstream of a second of the plurality of material receiving units, the at least one fluidizable conveying device having a decline and further including a first fluidizing element and a second fluidizing element, at least one of the first and second fluidizing elements being activatable separately from another of the first and second fluidizing elements, the method comprising: activating only the first fluidizing element of the at least one fluidizable conveying device having the decline when transporting the fluidizable powder material with the assistance of gravity to the first material receiving unit via a first of the outlets; and activating both the first and second fluidizing elements of the at least one fluidizable conveying device having the decline when transporting the fluidizable powder material with the assistance of gravity to the second material receiving unit via a second of the outlets, wherein the transporting of the fluidizable powder material to the first material receiving unit does not transport the fluidizable powder material through the second material receiving unit and the transporting of the fluidizable powder material to the second material receiving unit does not transport the fluidizable powder material through the first material receiving unit.
