The invention relates to motionless mixers and baffles thereof and includes a baffle having a pair of substantially symmetric opposing major surfaces generally helically twisted along a central longitudinal axis of the baffle and a first pair of substantially planar surfaces connecting the pair of major surfaces at one end of the baffle, one of the first pair of planar surface extending both substantially transversely and substantially parallel to the central longitudinal axis. The intersection of the first planar surface and one of the major surfaces forms an edge at the one end of the baffle. Such geometry enables a plurality of the baffles to be formed as a single insert unit by conventional injection molding techniques using only a pair of mold halves. The major surfaces are concave in cross-section normal to the longitudinal axis to form with a housing a pair of passages of generally ovoid (or elliptical) cross-section.

A motionless mixer baffle member, said baffle member being helically twisted symmetrically about a longitudinal axis and being defined by opposed major surfaces, which in a cross-section of the baffle normal to the axis are concave, extending along said axis from a first end to a second end of said baffle, said concavity of said major surfaces defining, when said baffle is installed in a tubular housing, with said housing, a pair of generally ovoid passages devoid of sharp corners one on either side of the baffle.
