Disclosed herein is a machine for producing expanded-grain cakes. The machine includes a frame, a mold unit, a grain supply unit, a grain transfer unit, a mold pressure arm, a drive unit, an open cam, a control unit and a cover unit. A precise charge of cereal grain is metered at the grain supply unit and in synchronism with the mold open cycle, distributed evenly over the mold cavity. Then with the mold unit clamped closed, the charge is heated and, at the end of the baking cycle, a preform is produced with gases at high pressure entrained therewithin. Upon release from the mold, the preform expands to a grain cake of the desired size. The machine controls the thermal energy input, the cycle frequency, the size of the grain charge, and the ejection trajectory. Several interrupts are used to ensure conformance to the control parameters and to enhance operator safety. |
