A grain cake baking machine having an upper mold, a ring mold and a lower mold, with the upper and lower molds sliding in the ring mold and defining a mold cavity, a first drive for moving the lower mold relative to the ring mold between a vent position and an intermediate baking position, and an unload position extending to the upper end of the ring mold for discharging the cake, a second drive for moving the upper mold relative to the ring mold between a load position out of the ring mold for loading grain and unloading a cake, and a baking position within the ring mold, a third drive for loading a charge of grain into the ring mold when the upper and lower molds are in the load positions, with the first drive moving the lower mold to the load position for venting the mold cavity, and heaters for the upper and lower molds. The first drive may include a shaft carrying the lower mold, a brake bar carried on the shaft, a brake for clamping the brake bar in a fixed position in the housing, a spring between the shaft and the housing for urging the shaft and lower mold away from the ring mold, a drive for moving the shaft and lower mold to the baking position, and a brake control to clamp the brake bar, shaft and lower mold in the baking position, with the spring means moving the lower mold to the vent position when the brake is actuated to release the brake bar. The brake mechanism also may be used with the upper mold alone and with both upper and lower molds as desired. A method of baking is also disclosed. |
