  • a conventional grain puffing apparatus has a structure of heating and cooking grains which have been input into a closed space, heightening the inner pressure of the closed space by vapor exhausted from the cooked grains, and extruding and puffing the grains to the outside at the state where the inner pressure of the closed space has been heightened.
  • ⁇ puffing apparatus as an apparatus for making foods good for health.
  • an energy efficiency drops because the conventional grain puffing apparatus should be heated by a special heating source.
  • the conventional grain puffing apparatus is complicated due to the special heating source.
  • a separate circuit for controlling the temperature of the conventional grain puffing apparatus should be essentially added.

  • the screw 20 has a double spiral structure of the first screw spiral 21 and the second screw spiral 22. The reason why the screw 20 has a double spiral structure is to intercept heat which is generated when grains gl are transferred from one end of the screw 20 to the other end thereof from flowing backward, that is, toward the one end of the screw 20 from the other end thereof.
  • At least one thread hitch 23 that connects threads forming the first screw spiral 21 and the second screw spiral 22 is formed on the other end of the screw 20.

  • the outer diameter of the screw groove 24 is preferably formed a , little smaller than the outer, diameter of the screw vale portion of the screw 20.
  • the cylinder 30 compresses the grains gl that is transferred by the screw 20 in a form of surrounding the outer circumferential surface of the screw 20, and makes the grains gl self-generate heat by themselves and changes the grains gl in a gel state by the compression action.
  • a first cylinder spiral 31 and a second cylinder spiral 32 are formed on the inner circumferential surface of the cylinder 30, in correspondence to the first screw spiral 21 and the second screw spiral 22, respectively.
  • the pitch of the first screw spiral 21 equals the pitch of the first cylinder spiral 31
  • the pitch of the second screw spiral 22 equals the pitch of the second cylinder spiral 32.
  • a grain inlet 33 is formed at one end of the cylinder 30, that is, at the end of the motor 10. Accordingly, grains gl are input into a space that is formed by the screw 20 and the cylinder 30 through the grain inlet 33.
  • the inner diameter of the cylinder 30 becomes smaller as it goes from the motor 10 to the puffing unit 40. Accordingly, distances dl, d2, d3, and d4 between the screw spirals 21 and 22 and the cylinder spirals 31 and 32 become gradually smaller. This is, dl is bigger than d2, d2 is bigger than d3, and d3 is bigger than d4.
  • the minimum inner diameter of the portion where the threads on the inner circumferential surface of the cylinder 30 are formed is larger than the outer diameter of the thread portion of the screw 20.
  • the puffing unit 40 includes a main body 41, a cover 42 and a clamp 43.

  • the other end of the motor 10 is opened.
  • the cover 42 closes the opened portion of the main body 41.
  • a grain outlet 421 through which puffed grains are discharged is formed on the cover 42.

  • the cutter 50 rotates at a given speed at the outside of the cover 42, and cuts the puffed grains g2 in desired size.
  • a reference numeral 55 in FIG. 1 denotes a motor for making the cutter 50 rotate.
  • a fixed amount of grains gl per unit time is input into a space that is formed by the screw 20 and the cylinder 30 through a hopper "H" and through the grain inlet 33 of the cylinder 30.
  • grains gl are input through the hopper "H" and through the grain inlet 33 of the cylinder 30, the grains gl are moved to the puffing unit 40 while the screw 20 rotates by the motor 10.
  • the grains gl make a friction with one another during the process that grains gl move to the puffing unit 40, and the grains gl make a friction with the outer circumferential surface of the screw 20 and the inner circumferential surface of the cylinder 30, to thereby generate frictional heat.
  • the grains gl are changed into a gel state by the frictional heat, as the grains gl moves from the grain inlet 33 to the puffing unit 40.
  • a puffing space a space which is formed by the screw 20 and the cylinder 30 increases together.
  • Grains gl move toward the puffing unit 40 continuously at the high temperature and high pressure state.

  • the temperature in the puffing space is a certain temperature or high
  • vapor that is evaporated from the grains gl flows backward, and heats the grains gl which are input into the grain inlet 33. Accordingly, as soon as the grains gl are input, the grains gl are changed into a gel state. As a result, there is a problem that it is difficult to make the grains gl transferred. Since the temperature of grains is lower than that of the puffing space, the grain puffing apparatus is cooled by the grains. Thus, if input grains are immediately heated, there is a problem that a cooling effect of the grain, puffing apparatus by grains cannot be expected.
  • a screw groove 24 is formed. Since grains of a gel state is engaged with the screw groove 24 in a ring shape, a kind of a wall is formed to prevent vapor from flowing backward toward the grain inlet 33.
  • the puffing unit 40 includes a main body 41, a cover 42 and a clamp 43. As described above, the main body 41 and the cover 42 are fixed by the clamp 43, and the clamp 43 is of a mechanically deformable structure.

  • the grains gl which have been transferred toward the cover 42 through the puffing space are discharged through the grain outlet 421.
  • the atmospheric pressure is relatively smaller than the pressure in the puffing space, the puffing space is expanded.
