<p>Parallel pairs of waffle irons (7, 9) are carried on a wheel (6) turning about an axis (4). Their alignment radiates away from the axis. Each iron is associated with a heat exchanger (14, 15). Fluid from a heater (22) is passed through these (14, 15), at a pressure below 12 bar. When closed, pairs of irons each lie together in a plane intersecting the wheel axis (4) radially. The wheel is spoked (5) and the irons are attached remotely from the axis. The fluid is supplied by an annular line (21) to which a radial feed line is connected via a rotary joint. Branches are provided to feed each heat exchanger, and similarly-configured return pipework is included. The heater is electrical, solar, geothermal or fired with solid, liquid or gaseous fuel. The fluid is a thermal medium, especially a food-compatible oil. Further details of the irons, their mountings and locking arrangements are provided. Their hinges lie parallel to the wheel axis. A cam system causes opening and closure of the irons, as the wheel rotates. The wheel includes a moving batter dispenser, to fill opened pairs of irons. More than 30 pairs of irons are included, preferably about 50 of them.</p> |
