As described above, the supply module 100 includes a container feeding device for feeding one or more standardized containers to a pallet 10 of a predetermined size, and a metering device for feeding rice or various materials to the container put in the pallet . Meanwhile, the supply module 100 may include various input devices for supplying various materials, but the present invention is not limited thereto.

The pallet 10, on which the material and container fed through the supply module 100 are placed, is guided to the cooking module 200.

Meanwhile, the pallet 10 may be conveyed by a predetermined conveying module 400, and the conveying module 400 may include a conveying device such as a conveyor belt. The delivery module 400 may be responsible for transporting the pallet 10 throughout the instant rice production apparatus 1 according to the present invention. 2, the pallet 10 may be passed through the inside of the high-pressure chamber 2, which will be described later.

The cooking module 200 is configured to perform the cooking of the rice and the material throughout the instant rice producing apparatus 1 according to the present invention and is not limited to the one constituted by any one of the apparatuses, And scope of the present invention. Also, the cooking process need not be continuous and other processes may intervene in the middle. That is, the material that has passed through the high-pressure chamber in the cooking process described later is introduced into the boiling chamber 270 again after passing through the sealing module 300. In this process, the sealing by the sealing module 300 is intervened in the middle of cooking , Whereby the cooking process by the cooking module 200 and the cooking module 200 is limited to any one of before and after the sealing process.

1, the cooking module 200 includes a primary water supply chamber 210, a pressurization chamber 220, a sterilizing chamber 230, a secondary water supply chamber 240, a cooking chamber 250, A chamber 260, a boiling chamber 270, and a cooling device 280. The respective portions are not limited to being continuously disposed or performing a continuous process.

The pallet 10 into which the container is introduced is first transferred to the primary water supply chamber 210. The primary water supply chamber is a device for injecting a predetermined amount of water into the container, and may include a predetermined water supply device.

The pallet 10 passing through the first water supply chamber 210 and having undergone the first water supply is transferred to the pressurization chamber 220. The pressurizing chamber 220 may block the external atmospheric pressure atmosphere and the subsequent cooking atmosphere and may be constructed of a sealed high pressure steam chamber. The pressurizing chamber 220 is provided with a high-pressure atmosphere of 1.5 to 2.5 kg / cm 2 to maintain a high-pressure atmosphere in the subsequent cooking process. That is, the pressurizing chamber 220 interrupts the pressure exchange between the sterilizing chamber 230 at the downstream end and the outside atmosphere.

The pallet 10 is then transferred to the sterilization chamber 230. The sterilizing chamber 230 is constituted by a high-pressure steam chamber, and the palette 10 is provided with a high-temperature atmosphere of a high temperature of several minutes and a high pressure of 1.5 to 2.5 kg / cm 2 to kill various bacteria in the material placed in the container. The sterilization chamber 230 maintains the pressure despite the introduction of the pallet 10.

At this time, the steam sterilizing chamber 230 is provided with a steam injector to spray hot steam to the rice and the material. The steam injector includes an upper nozzle 16 and a lower nozzle 18. The upper nozzle 16 injects steam at an upper portion of the pallet 10 and the lower nozzle 18 injects steam at a lower portion of the pallet 10. [ The steam can be sprayed in. Accordingly, the material contained in the container is injected in a three-dimensional manner, so that steam penetrates deeply and more reliable sterilization can be achieved.

On the other hand, for more effective sterilization, the steam can be supplied in a state of maintaining a high temperature by using various heating means. At this time, the heating means may be an electric heating device or various kinds of heating media, but is not limited thereto.

The pallet 10 having passed through the sterilization chamber 230 is transferred to the secondary water supply chamber 240. In the second water supply chamber 240, water of 60 ° C to 90 ° C is supplied again to the pallet 10, and the high temperature of the atmosphere in which the bacteria are not generated is maintained for several minutes so that the supplied water is sterilized As shown in Fig. Here, the water may have a waiting time for a predetermined time such that the water can be sufficiently absorbed into the material, and the waiting time may be about 2 to 5 minutes. At this time, as the temperature atmosphere is kept as described above, the water supplied may not boil over the pallet 10. The second water supply chamber (240) blocks pressure exchange between the sterilization chamber (230) and the cooking chamber (250).

As described above, since the first water supply chamber 210 and the second water supply chamber 240 are separately provided, the second water supply can be separately performed after the first water supply sterilization process. In the course of the water being absorbed by the rice passing through the sterilization chamber (230) after the first water supply, the water is partially steamed together with the hot steam, the sterilization is promoted in the process, and then the water is moved to the water supply chamber Insufficient water can be replenished. Therefore, moisture control of the material is facilitated, sterilization is promoted, and the reliability of the product can be improved.

The material to which the secondary water supply is made moves to the cooking chamber 250.

The material transferred to the cooking chamber 250 is subjected to a cooking process at a temperature of about 100 ° C to 120 ° C and a pressure of 0.5 to 1.2 kg / cm 2 for about 10 to 30 minutes. As the cooking process is performed, cooking of the material can be performed. As a result, the process from sterilization to the cooking process can increase the elasticity of the manufactured product by repeatedly raising and lowering the temperature, so that the texture of the finished product can be improved.

The material that has been cooked through the cooking chamber moves to the decompression chamber 260 so that it can be taken out to the outside. The decompression chamber 260 functions as a buffer for decompressing the internal pressure atmosphere so that the material can be taken out to the outside, and blocks the pressure circulation between the pressure in the high pressure chamber and the atmospheric pressure outside. That is, the decompression chamber 260 blocks pressure exchange between the outside atmosphere and the cooking chamber 250.

The pressure chamber 220, the sterilizing chamber 230, the secondary water supply chamber 240, the cooking chamber 250, and the decompression chamber 260 are connected to the high-pressure chamber 2 where a predetermined temperature and pressure atmosphere can be maintained, As shown in FIG. That is, as described above, in order to provide a proper cooking atmosphere for the material, a high-temperature and high-pressure atmosphere must be maintained.
