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).

A feed roller is formed with a generally cylindrical outer surface having raised portions arranged in a pattern that extends circumferentially around the surface. The raised portions are formed in distinct shapes. Preferably the distinct shapes are chevron shapes that retain dough between successive chevron shapes. The roller preferably has an annular ridge which prevents dough from escaping axially off the edge of the roller. In use, dough is feed between the feed roller and a mold roller. Some of the dough is retained on the outer cylindrical surface of the feed roller to provide a smooth surface for inserting the rest of the dough in mold cavities located in the mold roller.

A transfer apparatus for transferring a dough piece from a first processing station to the next, especially from a dough portioning device to a dough kneading device, includes a rotating dropping roller and a scraper. The rotating dropping roller is configured to release the dough piece from the first processing station. The scraper is associated with the dropping roller and is configured to support the dough piece released from the dropping roller. An oiling device is associated with the dropping roller and is configured to apply oil onto an outside surface of the dropping roller.
