The present invention relates to a roller to be used as part of an apparatus for spreading and flattening dough, in the context of an industrial bread making line. The dough spreading roller of the present invention is comprised of multiple offset discs installed on a shaft, which accords the roller with an undulating surface. The dough spreading roller of the invention provides a massaging and kneading force to the dough from underneath the conveyor belt. The dough spreading roller also includes end nuts which serve to level the edges of the conveyor belt level during use. The conveyor belt is also provided with a calendar roller located above which provides an opposing and flattening force to said dough spreading roller. The dough is therefore processed between the calendar roller, conveyor, and underlying spreading roller. The invented configuration provides a gentler, less vigorous treatment of the dough which facilitates industrial manufacture of a softer, less processed dough.

A food dough extrusion machine (10). The machine has a platform (2) and at least one extrusion unit (1) supported by the platform (2). The extrusion machine (10) has a guidance (3) by which the at least one extrusion unit (10) is supported on the platform (2) and by which the at least one extrusion unit (10) is adjustable relative to the platform (2) and/or removable from the platform (2).
