<p>There is shown a roller (10, 30, 40) for pressing and working a dough ball (D) into a pizza shell (P). In its preferred form, the roller (10, 30, 40) is in the form of a spherical cluster (30, 40) of balls (32, 46), which are molded or otherwise formed on a polygonal core (44). The spherical cluster (30, 40) is rotatably contained within a complementary spherical shell (14) carried on the lower end of a fluid duct (20). Olive oil or other material flowing through the duct (20) will flow ports (22, 24, 28) in the shell (14) to be carried by the cluster (30, 40) of balls (32, 46) and distributed over (14) the dough ball (D). Ports (24) in the side of the duct (20) allow the oil to flow around the shell (18) to drip directly onto the dough ball (D) near the outer edges thereof. A conical hood (18) round the cluster (30, 40) of balls (32, 46) and the carrier block and retain any olive oil vapors that otherwise may be inhaled by bakery workers.</p> |
