Abstract
A method for pneumatically handling material having a slurry-like consistency such as chicken hatchery waste material includes a hopper for accepting the waste material, a receiver for accumulating the waste material and duct work which is connected between the hopper and the receiver. The system also includes a blower for creating reduced pressure in the receiver with respect to the hopper whereby the waste material is drawn from the hopper to the receiver. The system also includes a valving arrangement whereby a volumn of reduced pressure is maintained within the receiver above the accumulated waste material, the pressure being reduced with respect to the outside ambient, thereby causing air from the outside ambient to enter into a discharge aperture in the bottom of the receiver, through the accumulated waste material to the volumn of reduced pressure, thereby agitating, loosening and effecting the rapid discharge of the accumulated waste material through the discharge aperture.
