    摘要： A device for altering a feed stock is made of a structure for passage of a feed stock. The structure can be either an extruded unibody structure, or a nested structure. The structure has an interior and an exterior section, and a longitudinal axis, and walls defining two sets of open-ended passages which extend along the longitudinal axis. The two sets of passages have different cross sectional shapes or dimensions with respect to each other. When the structure is nested, at least one set of channels have a cross section in the shape of truncated arcs. A method for making the unibody structure involves extruding a plasticized raw material mixture through a die, followed by heat-treating. A method of altering a feed stock which involves passing a feed stock into the device through one set of passages to cause an altering of the feed stock, and thereafter passing the output stream into and through the other set of channels to the exterior of the device.
