Each is provided with an airtight door 20 which can be opened and closed so that the pallet 10 can be moved in or out.

The hermetic door 20 includes a front chamber chamber, a rear chamber chamber, a pressurization chamber 220, a sterilization chamber 230, a secondary water supply chamber 240, a cooking chamber 250, and a decompression chamber 260. ) Are placed between each. Accordingly, the hermetic door 20 is disposed at the front and rear ends of the main chamber 2, and between the pressurization chamber 220 and the sterilization chamber 230, the sterilization chamber 230 and the two inside the main chamber 2, respectively. It is disposed between the primary water supply room 240, between the secondary water supply room 240 and the cooking chamber 250, and between the cooking chamber 250 and the decompression chamber 260 to partition each space. On the other hand, each hermetic door 20 has essentially the same configuration.

Specifically, the hermetic door 20 has a predetermined thickness and area, and has a gate plate 22 having an opening portion 30 formed therein so that the pallet 10 can be introduced therethrough, and is displaced in an up and down direction so that the opening portion ( And a slide gate 27 for performing the opening and closing of the slide 30, and a predetermined opening and closing module for displacing the slide gate 27.

 The container containing the material and the material carried out from the main chamber 2 to the outside is transferred to the sealing module 300 to achieve a quick sealing. In this case, preferably, the cooked material is not sealed, and thus the transport device in charge of transporting the material may maintain a sealed state in order to prevent bacteria contamination by inflow of outside air.

The sealing module 300 may have a predetermined condensation removing device 310 to prevent condensation of water vapor generated from the cooked material. The condensation removing apparatus 310 has a double outer wall 14 structure, and provides the filtered dry air of 60 ° C. or more therein, and exhausts the condensation to remove condensation due to water vapor therein.

In addition, the sealing module 300 may include a vacuum pump 320 and a feeding device 330 for sealing the container containing the cooked material.

Materials that do not go through can be used directly in the process. Therefore, the pre-cooking process is unnecessary in the cooking process, thereby reducing the overall instant rice production cost. In addition, it is possible to prevent the mixing of foreign matters, breeding of bacteria, etc. in the preceding cooking process, thereby enabling a more reliable product production.

In addition, since the water supply is made a plurality of times through the first and second water supply process, it is easy to control the moisture of the material, and it is possible to flexibly cope with the change of absorption rate of the material according to the cooking process, so that the weight of the produced product is poor, Quality defects such as poor texture can be minimized.

3) Step 3 (Pallet 10 is introduced into the sterilization chamber 230 from the pressure chamber 220): When the pressure in the pressure chamber 220 is in equilibrium with the pressure in the sterilization chamber 230, the pressure chamber 220 The airtight door 20B between the sterilization chamber 230 and the pallet 10 is introduced into the sterilization chamber 230. At this time, by providing a pressure to the pressure chamber 220 in the step 2, the pressure inside the pressure chamber 220 is the same as the pressure of the sterilization chamber 230, the hermetic door 20B is opened to the sterilization chamber 230 and Despite the pressure distribution between the pressure chamber 220 is maintained pressure of 1.5 ~ 2.5kg / ㎠ without changing the pressure inside the sterilization chamber (230). Of course, at this time, the airtight door 20C between the sterilization chamber 230 and the secondary water supply chamber is kept closed, and as described above, the pressure chamber 220 serves as a pressure ballast to block a subsequent cooking atmosphere and an atmospheric pressure atmosphere. Will be performed.

[Revision 12.03.2015 under Rule 91]

5) Step 5 (Pallet 10 input from the sterilization chamber 230 to the secondary water supply chamber): When the pressure in the secondary water supply chamber 240 is in equilibrium with the pressure in the sterilization chamber 230, the secondary water supply chamber ( The airtight door 20C between the 240 and the sterilization chamber 230 is opened to inject the pallet 10 from the sterilization chamber 230 into the secondary water supply chamber 240. At this time, since the pressures of the sterilization chamber 230 and the secondary water supply chamber 240 are the same, the pressure of the sterilization chamber 230 is constant despite the pressure distribution due to the opening of the hermetic door 20C and the discharge of the pallet 10. Can be maintained. Of course, at this time, the hermetic door 20D between the secondary water supply chamber and the cooking chamber 250 and the hermetic door 20C between the sterilization chamber 230 and the pressure chamber 220 remain closed.

The pressure in the seal 250 can be kept constant. In more detail, the pressure of the sterilization chamber 230 maintains 1.5 ~ 2.5kg / ㎠, the pressure of the cooking chamber 250 maintains 0.5 ~ 1.2kg / ㎠.

If there is no secondary water supply room 240, the pallet 10 is directly put into the cooking chamber 250 from the sterilization chamber 230, the airtight type between the sterilization chamber 230 and the cooking chamber 250 When the door 20D is opened, the pressure in the sterilization chamber 230 flows into the cooking chamber 250 so that the sterilization chamber 230 and the cooking chamber 250 cannot maintain respective pressures.

However, according to the present invention, since the secondary water supply chamber 250 is located between the sterilization chamber 230 and the cooking chamber 250 and the airtight door 20 disposed between each is opened and closed as described above, 2 When the pallet 10 moves from the sterilization chamber 230 to the cooking chamber 250 via the primary water supply room 240, pressure distribution between the interior of the sterilization chamber 230 and the interior of the cooking chamber 250 is blocked. That is, when moving the pallet 10 from the sterilization chamber 230 to the secondary water supply chamber 240, only the airtight door 20C between the sterilization chamber 230 and the secondary water supply chamber 240 is opened and the secondary The pressure of the water supply chamber 240 is maintained like the sterilization chamber 230, and then the pressure of the secondary water supply chamber 240 is equal to the cooking chamber 250 while the secondary water supply chamber 240 is sealed. When the pallet 10 is moved from the secondary water supply chamber 240 to the cooking chamber 250, the sterilization chamber 230 is opened by opening only the airtight door 20D between the secondary water supply chamber 240 and the cooking chamber 250. ) And the pressure in the cooking chamber 250 can be maintained in a unique state, respectively. Accordingly, the secondary water supply room 240 may serve as a predetermined pressure ballast.

8) Step 8 (Pressure Reduction Chamber 260 Pressure Adjustment): In addition to performing cooking in the cooking chamber 250 in a closed state, the pressure inside the decompression chamber 260 is adjusted. At this time, the decompression chamber 260 is in a closed state, and both the hermetic door 20E between the pressure chamber and the cooking chamber 250 and the hermetic door 20F at the rear end of the decompression chamber 260 are kept closed. In a closed state, a pressure of 0.5 to 1.2 kg / cm 2, such as the cooking chamber 250, is applied to the inside of the decompression chamber 260.

[Revision 12.03.2015 under Rule 91]

9) Step 9 (Pallet 10 is introduced from the cooking chamber 250 to the decompression chamber 260): When the pressure inside the decompression chamber 260 is in equilibrium with the cooking chamber 250, the decompression chamber 260 and the cooking chamber The airtight door 20E between 250 is opened, and the pallet 10 is discharged | emitted to the pressure reduction chamber 260. FIG. At this time, since the pressure of the pressure reducing chamber 260 and the cooking chamber 250 is the same as described above, the pressure of the cooking chamber 250 may be maintained despite the opening of the hermetic door 20 for discharging the pallet 10. have. Of course, at this time, the hermetic door 20F behind the decompression chamber 260 remains closed, and the hermetic door 20D between the cooking chamber 250 and the secondary water supply chamber 240 is also in a closed state. Accordingly, the decompression chamber 260 serves as a pressure buffer or a pressure ballast for depressurizing the internal pressure atmosphere, and may block the pressure flow between the pressure in the main chamber 2 and the external atmospheric pressure.

[Revision 12.03.2015 under Rule 91]

10) Step 10 (Pallet 10 is discharged from the pressure reducing chamber 260 to the outside): Then, the pressure-sensitive door 20E between the pressure reducing chamber 260 and the cooking chamber 250 is closed to close the pressure reducing chamber 260. After the pressure in the decompression chamber 260 is equal to the external atmospheric pressure in one state, the pallet 10 is discharged through the hermetic door 20F behind the decompression chamber 260. Of course, at this time, the airtight door 20 between the decompression chamber 260 and the cooking chamber 250E is closed in spite of the opening of the airtight door 20F behind the pressure chamber 220 and the discharge of the pallet 10. And the pressure in the cooking chamber 250 can be kept constant.
