[0029] Specifically, the production line 100 for room temperature boxed rice provided by the present application comprises, in sequence, a rice cooking area 1, a metering and filling area 2, an aseptic packaging area 3, a sterilization area 4, and a testing area 5. The rice cooking area 1 breaks away from the previous process of directly placing rice into the packaging box for steaming. Instead, the rice washing module 11, the rice mixing module 12, the rice steaming module 13, and the rice dehumidification module 14 are rationally arranged. That is, the rice washing module 11 and the rice mixing module 12 are located on one side of the rice steaming module 13, and the rice dehumidification module 14 is located on one side of the rice washing module 11, the rice mixing module 12, and the rice steaming module 13. This allows the conveying device 17 to deliver the steamed rice to the metering and filling area 2 for packaging. Compared with the previous steaming method of boxed rice, this avoids the problem of rice in the steam box being burnt or undercooked due to uneven steam. In addition, the present application sterilizes the rice after packaging. Compared with the previous method of directly adding antibacterial agents to the rice in the packaging box, no antibacterial related contents are added in the present application, ensuring the safety of the rice.
[0030] The rice washing module 11 in the rice cooking area 1 is used to wash the rice grains, that is, to remove impurities in the rice grains. In addition, the rice washing module 11 is also provided with a rice washing and soaking device for fully absorbing water after the rice grains are soaked. In a preferred embodiment provided in the present application, the rice washing module 11 uses a rice washing machine for washing.
[0031] The rice preparation module 12 is equipped with a water injection unit 121, which is used to mix rice grains and water in a certain ratio, so that the rice grains cooked in the rice cooking module 13 are clearly separated. A stirring unit 122 is also provided behind the water injection unit 121, which is used to evenly mix the rice grains and water and position them in the inner container of the cooking pot 131. In a preferred embodiment provided in this application, the rice preparation module 12 is generally integrated into a rice washing machine, and is used to prepare the rice after washing through the water injection unit. Of course, the rice preparation module can also be a separate device.
[0032] In addition, the rice preparation module 12 is also provided with a seasoning unit for improving the taste of rice, preventing it from sticking to the pan, and enhancing the aroma.
[0033] The rice cooking module 13 heats the cooking pot 131 by electromagnetic control. It is understood that electromagnetic heating for cooking rice can ensure uniform heating and precise control, ensuring that the cooked rice grains are evenly heated to avoid overcooking or half-cooking.
[0034] The rice cooking module 13 includes at least two cooking pots 131 for cooking rice. It is understood that the rice cooked in the rice cooking module 13 can be a variety of rice types, such as white rice and black rice. Using multiple cooking pots 131 allows for the cooking of a variety of rice varieties in small batches. In a preferred embodiment provided herein, the cooking pots of the rice cooking module 13 are IH pressurized rice cookers.
[0035] The rice dehumidification module 14 includes at least a pouring unit 141 for pouring out the rice cooked in the inner pot of the cooking pot 131 and a loosening unit 142 for loosening the poured rice to remove moisture. It is understandable that after the rice is cooked, it is necessary to dissipate heat to ensure that it can be stored in the packaging box for a long time after subsequent packaging. The rice dehumidification module 14 also includes a washing unit 143, which is used to wash the inner pot after pouring out the rice and transport it to the rice washing unit. In a preferred embodiment provided in the present application, the pouring unit is specifically a reversing machine, and the loosening unit 142 is specifically a rice loosening machine.
[0036] It should be noted that, during the process of transferring the rice from the rice steaming module 13 to the rice desiccant module 14 , a vinegar adding device is provided for spraying vinegar on the cooked rice to make the rice softer.
[0037] It should also be noted that the conveying device 17 can convey the inner pot in the rice washing module 11, rice preparation module 12, rice steaming module 13, and rice dehumidification module 14 by either a robot or a conveyor belt 171. A conveyor belt 171 is provided behind the rice dehumidification module 14 to return to the rice washing module 11. After conveying the cooked rice to the rice dehumidification module 14, the inner pot returns to the rice washing module 11 for the next conveyance.
[0038] The metering and filling area 2 is used to quantitatively fill the packaging box with rice. Metering and filling involves placing a quantitative amount of heat-dissipated rice into the packaging box, which is then sealed in the sterile packaging area 3. The sterilization area 4 is used to heat, sterilize, and cool the sealed packaging box, rather than directly placing an antibacterial agent inside the box. In a preferred embodiment provided herein, the metering and filling area 2 is equipped with a rice metering machine, and the sterile packaging area 3 is equipped with a packaging machine for gas displacement sealing.
[0039] The detection area 5 includes at least a seal detection module 51 and a weight detection module 52. The seal detection module 51 is used to detect whether the package is completely sealed, and the weight detection module 52 is used to detect whether rice is placed in the sealed package. In a preferred embodiment provided in this application, the seal detection module 51 is equipped with a seal detection device, and the weight detection module 52 is equipped with a weight detection machine to perform gas displacement sealing.
[0040] The specific working principle of the production line 100 of room temperature boxed rice provided by the present application is as follows: rice, black rice, or millet is placed in the inner pot on the conveying device 17, then washed by the rice washing module 11. After washing, it is soaked to fully absorb water. Then, water is added to a certain ratio through the water injection unit 121 of the rice blending module 12. During this process, seasonings such as sesame oil can also be added through the seasoning unit to enhance the taste of the steamed rice. Then, the inner pot is transported to the rice steaming pot 131 of the corresponding type in the rice steaming module 13 for steaming. After steaming, the rice is poured out from the inner pot by the pouring unit 141 of the rice dehumidification module 14, and the rice is loosened by the loosening unit 142 to facilitate heat dissipation. The rice is then added to the packaging box in a fixed amount through the metering and filling area 2. Next, the packaging machine in the sterile packaging area 3 performs gas displacement sealing. The packaging box and the film are constructed of oxygen-isolating materials to prevent the growth of bacterial colonies. The process is carried out in a sterile environment to reduce contact with fungi. The sealed boxed rice is heated, sterilized, and cooled in the sterilization zone 4, and then the entire product is inspected in the inspection zone 5. The sealing detection module 51 detects whether the package box is completely sealed. Finally, after confirmation by the weight detection module 52, it is shipped to ensure that the product maintains its taste while being conveniently stored at room temperature. It can be seen that the working principle of this production line avoids directly adding antibacterial agents to the rice in the package. Instead, it sterilizes the rice after packaging, ensuring that the rice is delicious while avoiding the consumption of rice with antibacterial agents that poses a potential risk to the user's health. Moreover, after the rice is steamed in the cooking zone 1, it is filled in the metering and filling zone 2 to avoid uneven steam distribution during the steaming process of the rice in the package, which may cause the rice in some areas to be burnt or undercooked.
