Abstract
An apparatus and method for continuously dispensing particulate material utilizes a transfer vessel which may be placed at a location spaced below and apart from a dispensing vessel. Particulate material may be transferred from the transfer vessel to the dispensing vessel by aerating the particulate material and pneumatically transferring the material to the dispensing vessel through a suitable pipeline. Valving on the dispensing vessel and the transfer vessel prevents loss of pressure from the system during operation. The air supply for transfer and dispensing may be provided by one source. The dispensing unit may continuously dispense material through repeated cycles of transfer of material from the transfer vessel.
