## Abstract

The present invention provides a method of manufacturing packaged completely cooked rice or a packaged completely cooked mixed rice, comprising a steaming process of sterilizing and primarily cooking the contents in the opened container by filling the controlled steam having high pressure and high temperature in the steaming unit; a cooking process of additionally sterilizing the contents in the opened container by filling the controlled steam having high pressure and high temperature in the steaming unit, and supplying water in the contents, and then completely cooking the contents; and a sealing process of supplying clean nitrogen gas to the completely cooked contents in the sealing unit and sealing the upper end of the opened container with the lid film, wherein the steaming unit, cooking unit and the sealing unit are connected in turn in the one container so that the opened container can be input into and output from each of the units. Therefore, the contents selectively combined from various cereal crops including rice, nuts and other additives including powders of the cereal crops, the nuts or the like are provided in a completely cooked state so that a user can eat instantly without a separate heating process.

## Claims

### Claim 1

An apparatus for manufacturing completely cooked rice or completely cooked mixed rice, in which multiple processing units are provided in one chamber that desired high pressure and high temperature steam is supplied, comprising:
a steaming unit which is filled with controlled steam having high pressure and high temperature in order to sterilize and primarily cook contents in an opened container;
a cooking unit which is filled with the controlled steam having high pressure and high temperature in order to additionally sterilize the contents in an opened container and in which water is supplied to the contents and the contents is completely cooked; and
a sealing unit in which clean nitrogen gas is supplied to the completely cooked contents and an upper end of the container is sealed with a lid film,
wherein the steaming unit, cooking unit and the sealing unit are connected in turn in the one chamber so that the opened container can be input into and output from each of the units.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the steaming unit and cooking unit are respectively provided with a high pressure steam controlling part in which the desired high pressure and high temperature steam generated from the steam chamber is adjusted to a proper pressure and then introduced into each of the steaming unit and cooking unit.

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein a damping unit which can control the pressure is disposed among the units, and a steam pressure controlling part which can remove a pressure difference from the rear unit by introducing or discharging the high pressure steam is disposed at each of the damping units.

### Claim 4 (depends on 3)

The apparatus according to claim 3, wherein the cooking unit further comprises a water shower system in which multiple nozzles are arranged in order to supply a desired amount of water necessary for the primarily cooked contents in the opened container, and the nozzles are arranged so as to be corresponding to a size and arranged type of each opened container and operated in a piston manner so that a precise amount of water is uniformly sprayed on the cooked contents.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein the cooking unit further comprises an extra insert system which additionally supplies a solid matter comprising various spices, seafood and edible ingredients or the solid matter mixed with a liquid matter to the contents in the opened container transferred from the previous steaming unit.

### Claim 6 (depends on 1)

A method of manufacturing packaged completely cooked rice or packaged completely cooked mixed rice by using the apparatus according to claim 1, comprising:
a steaming process of sterilizing and primarily cooking the contents in the opened container by filling the controlled steam having high pressure and high temperature in the steaming unit;
a cooking process of additionally sterilizing the contents in the opened container by filling the controlled steam having high pressure and high temperature in the steaming unit, and supplying water in the contents, and then completely cooking the contents; and
a sealing process of supplying clean nitrogen gas to the completely cooked contents in the sealing unit and sealing the upper end of the opened container with the lid film,
wherein the each process is performed by the steaming unit, cooking unit and the sealing unit in turn which are provided in the one chamber during the opened container can be input into and output from each of the units.

### Claim 7 (depends on 6)

The method according to claim 6, wherein, in the steaming process, an inner pressure of the steaming unit by the steam is kept in 1.2˜3.0 kg/cm2, and a process time is carried out for 2˜5 minutes.

### Claim 8 (depends on 6)

The method according to claim 6, wherein, in the cooking process, an inner pressure of the cooking unit by the steam is kept in 0.5˜2.0 kg/cm2, and the process time is carried out for 15˜40 minutes.

### Claim 9 (depends on 6)

The method according to claim 6, wherein, in the sealing process, an inner pressure of the sealing unit by the steam is kept in 0.1˜1 kg/cm2 so that external air is prevented from being contacted with the sterilized and completely cooking contents.

### Claim 10 (depends on 6)

The method according to claim 6, wherein the cooking process further comprises an extra insert process step of supplying a mixture selectively combined from various spices, seafood and edible ingredients to the contents in the opened container.

### Claim 11 (depends on 2)

The apparatus according to claim 2, wherein a damping unit which can control the pressure is disposed among the units, and a steam pressure controlling part which can remove a pressure difference from the rear unit by introducing or discharging the high pressure steam is disposed at each of the damping units.

### Claim 12 (depends on 11)

The apparatus according to claim 11, wherein the cooking unit further comprises a water shower system in which multiple nozzles are arranged in order to supply a desired amount of water necessary for the primarily cooked contents in the opened container, and the nozzles are arranged so as to be corresponding to a size and arranged type of each opened container and operated in a piston manner so that a precise amount of water is uniformly sprayed on the cooked contents.
