A continuous mixer (32) is disclosed which can be used for mixing of incoming product streams (22, 24) of different characteristics respectively to yield a final product stream (26) of predetermined, consistent characteristics. The mixer (32) includes an elongated housing (42) having a pair of product input ports (50, 52) and an output (64), with a pair of elongated, axially rotatable, mixing screws (44, 46) located within the housing (42). The screws (44, 46) include a series of outwardly projecting mixing elements (114) preferably of pyramidal design and arrayed in a helical pattern along the length of the screws (44,46). The mixer (32) may be used in a processing system (20,200) having individual product lines (28, 30, 204, 206) coupled to the mixer (32), and is especially useful for processing of incoming meat streams (22,24) of different fat/lean ratios, to give a final comminuted output stream (26) of an intermediate and essentially constant fat/lean ratio. Preferably, the product lines (204,206) are each equipped with a combined preblender and pumping device (202).

1. A screw set for a mixer, comprising: a pair of elongated, side-by-side, axially rotatable mixing screws each having a central section and a series of mixing elements each being generally pyramidal in shape projecting outwardly from said central section, said mixing elements each having a base
1. A screw set for a mixer, comprising: a pair of elongated, side-by-side, axially rotatable mixing screws each having a central section and a series of mixing elements each being generally pyramidal in shape projecting outwardly from said central section, said mixing elements each having a base which is generally diamond-shaped in plan configuration with four converging sidewall surfaces extending outwardly from said base terminating in an apex-like outer end having a surface area less than the surface area of the base, at least certain of said elements being oriented in a helical pattern along at least a portion of said central section. 2. The screw set of claim 1, each of said screws having an input section and presenting helical fighting along the length thereof, and an output section extending from the end of said input section, said mixing elements being located on said output section. 3. The screw set of claim 2, the fighting of said input sections of said screws being intermeshed, and the mixing elements of the output sections of said screws also being intermeshed. 4. The screw set of claim 1, the diamond-shaped base having two pairs of substantially parallel base surfaces, one of said base surface pairs having a length greater than the other of said base surface pairs. 5. The screw set of claim 4, the base surfaces of one of said base surface pairs lying along respective, parallel first helices of a first, substantially equal pitch, and the base surfaces of said other of said base surface pairs lying along respective, parallel, second helices of a second, substantially equal pitch, said second pitch being smaller than said first pitch.
