First, the submarine soldiers' meals.
First of all, the submarine soldiers shoulder the national mission, and we want to praise them. The meals of submarine soldiers are generally based on various quantitative meat, vegetables, eggs and naval rations. There are also some canned drinks, fruits and so on. But these are also principled, because submarines can't cook with naked fire, and they can only use some special cooking methods, such as steaming or roasting. In this case, the submarine soldier's food is relatively simple. Don't eat some ingredients with strong flavor, in order to avoid worsening the air. In addition, don't eat natural ingredients such as beans, sweet potatoes and radishes to avoid farting.
Second, the space is narrow.
The space in the submarine is very small. Although there are officers' canteens and officers' canteens, they are not spacious. Simply put, it is to set up a dining table where the soldiers sleep, and then clean the dining table after eating. Some leftover food, avoid cooking and eating too much residue to take up space. Kitchen garbage and residual garbage need to be classified, and solid and liquid need to be subdivided. If the liquid is discharged to treat solids, it needs to be discharged or crushed and brought back to the port for treatment. This practice is to avoid the exposure of floating objects at critical moments. In some emergencies, you can only eat canned food or cold rice instead of hot food. Sometimes eating is a task. If there is a task, there is a time limit, and it must be completed within the specified time.
The submarine itself is not ventilated, which will lead to a bad appetite and a person may get stomach trouble. Generally speaking, submarine soldiers are very distressing.
