Abstract
An apparatus and method for the pneumatic conveyance of bulk material and like products in a horizontal or inclined feed pipe which is filled with the product and is supplied with a gas along its length. The feed pipe has an elongated single chamber with an inlet and an outlet. The inlet is constructed so that the product will continuously flow into the inlet under the force of gravity. A plurality of individual percolation inlets are provided and which communicate with the lower region of the feed pipe. Each of the percolation inlets is connected to a gas supply. The pressure level of the gas supply and the size of the percolator inlets are dimensioned such that the gas is permitted to be continuously supplied to the feed pipe slowly and without turbulence in such quantity that the product is permeated beyond its capacity with the gas and thus undergoes an expansion in its volume which progressively increases along the length of the feed pipe from the inlet to the outlet while the feed pipe remains in communication with the hopper.
