ABSTRACT:
A static device and method of making is disclosed for mixing matter flowing therethrough. The invention comprises a tube having a polygonic cross section defining a plurality of corners. The tube is spirally twisted with the plurality of corners forming a plurality of helixes for causing the matter flowing through the tube to rotate in accordance with the plurality of helixes. In a first embodiment of the invention, the static device provides a static mixing device. In a second embodiment of the invention, the static device includes a plurality of apertures defined in the helix for providing a static separating device.
