A device for altering a feed stock comprising an extruded unibody structure for passage of a feed stock therethrough, the structure comprising an interior and an exterior section, and a longitudinal axis, and walls defining two sets of open-ended passages which are essentially parallel to the longitudinal axis, one set of passages being primary channels, and the other set of passages being egress conduits, each primary channel lying adjacent to an egress conduit or to the exterior of the structure. The passages of one set can be manifolded together. The device can have means for isolating the egress conduits from the feed stock. A method for making the device which involves extruding a plasticized raw material mixture through a die to form a unibody structure, followed by heat-treating. A method of altering a feed stock which involves passing a feed stock into the device through the primary channels to cause an altering of the fees stock, and thereafter passing the output stream into and through the egress conduits to the exterior of the device.
