Apparatus for transporting pneumatically suspended particulates from a source to a plurality of receivers

A vacuum conveying system for transporting pneumatically suspended particulates from an upstream particulate source to a plurality of downstream particulate receiving means comprising:

• a continuous primary material transport conduit having a plurality of elongated generally horizontally extending conduit portions with each downstream extent of said conduit portions being spaced below the adjacent upstream extent of the downstream adjacent one of said conduit portions;
• said primary material transporting conduit having adjacent ones of said conduit portions connected by transition conduit portions, respectively, a plurality of particulate receiving means, branch conduits communicating between said particulate receiving means and said conduit portions downstream of the upstream section of said transition conduit portions, respectively;
• vacuum producing means for obtaining a vacuum in a selected one of said particulate receiving means whereby pneumatically suspended particulate from such a source are transporatable by suction to said selected one of said particulate receiving means;
• and each of said transition portions extending at an upward acute angle with respect to the central axis of the downstream conduit portion of said conduit portions connected thereby to inhibit the flow of particulate therethrough when said vacuum producing means discontinues the vacuum to said selected one of said particulate receiving means.
