Extruding and cutting frozen confections containing edible particulates

An apparatus for manufacturing an extruded frozen confection, comprising;

• (a) a first conduit disposed to accept from suitable blender means, a first flow of a first material, and
• (b) a first diverter means opening into said first conduit is disposed to enable the extraction or injection of said first material into or out of said first conduit at a rate equal to or greater than said first flow, forming a first intermittent flow downstream in said first conduit, and,
• (c) a second conduit disposed to accept from suitable blender means, a second flow of a second material, and,
• (d) a confluence of said first conduit and said second conduit, downstream from where said first diverter means joins said first conduit, whereby when said first diverter means is extracting said first material from said first conduit at a rate greater than said first flow, said first material cessates its entry into said confluence and reverses direction to flow towards said first diverter means, thus allowing a transverse section of said confluence to be filled exclusively with said second material from said second conduit, and alternatively when said first diverter means is injecting said first material into said first conduit, a section of said confluence is filled with said first material from said first conduit.
