The submarine works underwater for a long time, how does the crew inside solve the problem of eating

In an enclosed space, if human beings want to live, there must be two conditions, the first is food and water, and the second is air, and air is crucial, that is, how the oxygen in the air is obtained. In a closed space, food and water can be prepared in advance and maintained for a certain length of time, this can be calculated, but air can also be calculated and manufactured, this is in a closed space, and it is also a common way of thinking in submarines.

Air and water: Air and water are already brought inside the submarine when the submarine is diving, and there are special tools for conversion, so it can be solved.

The nuclear submarine is equipped with oxygen and water storage, so the crew can stay alive for more than 10 days underwater.

It will be stored, and the amount of water that each crew member can drink will be strictly limited, and their domestic water will be limited.

They eat, sleep, relax, be on duty on the submarine every day, and are very planned; They can't cook over an open flame in a submarine, so they usually eat some quick food products, including canned food, or can cook some simple meals in an electric oven.

The daily life of submariners is very hard, and they need to use some electric ovens or electric cookers to make their own meals when they eat underwater, but the ingredients in them are relatively complete.

Although it is reported that their meals are very rich, in fact, under the water they prefer to eat canned food, because cooking over an open flame consumes a lot of oxygen, because the food is made on an electric stove and is not delicious.

The amount of fresh food required for the voyage is loaded in advance, which is basically military food, packaged in composite film and does not need to be heated. There are strict restrictions on the use of water, and the amount of water used is quantitative, after all, the water tank of the submarine can't bring much fresh water, and the submarine also has a seawater desalination device, but it is basically used to flush toilets and the like, which is not very useful. There are very few fresh fruits and vegetables, and there are still a few days before the voyage, and then vitamins are the main ones.

Supplies loaded by submarines before they go to sea.

The food in the submarine is all supplied from the shore, and it is all brought with its own food

Submarines generally go to sea for at least one or two months, and the fresh vegetables and fruits brought with them cannot be stored for a few days, so in addition to eating fresh vegetables just a few days before going to sea, other times can only eat dehydrated vegetables + processed vacuum-preserved meat + water + rice, and take vitamins to supplement the nutrients that are lacking due to insufficient light.

There is a water machine on the submarine, which can make drinking water, but the power is very small, so it is extremely luxurious to take a bath on the submarine, unless it is hot to jump into the sea to swim, however, the submarine that performs military tasks always releases the crew to swim, is this a submarine.

Before and after the submarine is launched, the air inside can be used up in a while, and the sodium peroxide medicine plate needs to be unsealed and reacted with the carbon dioxide exhaled from the boat to produce oxygen.

There is always spare food on the submarine, and the logistics of the army are quite good.

They always prepare food before going to sea, and usually prepare some compressed biscuits and the like.

Personally, I think that there must be a restaurant in the submarine, or the soldiers will bring the compressed food they need for travel.

It's that there are special cooks on the submarine to cook for the people on board, after all, rice is very important.

Revealing the real underwater life of submariners is unbearable for ordinary people, but the salary is very attractive.

The space is small, the supply is not good, the mental pressure is high, and there is noise trouble.

Claustrophobic spaces can be devastating, and prisons can occasionally let off steam.

Stay in a slap place for a few months, and keep focusing.
