PURPOSE:To obtain expanded cakes having uniform qualities, without loss of the nutrients, in a short time, by heating the raw grains such as cereal grains in the chamber of a grain expander, and at the same time, introducing hot compressed air into the chamber. CONSTITUTION:The lid 6 of the main body of the chamber 3 contained in the container cylinder 4 is opened, the raw grains such as rice, barley, macaroni, dried noodles, etc. are charged into the chamber 3, the lid 6 is closed, and the chamber 3 is heated under rotation with the motor 10. At the same time, the compressor 15 is energized, the compressed air pressurized to 1-15kg/cm<2>G is introduced into the heat exchanger 15 through the air filter 28 and the pipe 16, heated at about 100 deg.C, sent to the assistant heater 2 placed above the container cylinder 4 through the pipe 17, heated at about 120 deg.C by the heat source for heating the chamber 3, introduced through the pipe 21, the stop valve 22, the rotary swivel joint 23 and the connecting pipe 24 to the chamber 3 until the pressure in the chamber 3 reaches 3-10kg/cm<2>G, when the lid 6 is opened to cause the instantaneous pressure reduction and the expansion of the raw grains. |
