In the 20,000 acres of orchards, agricultural robots pollinate various fruits in the orchard "unmanned". Pineapples, sugar cane, peanuts, pears, lychees, nuts (fruits), mangoes, kiwis, loquats, apples, pomegranates, watermelons, strawberries, apricots, coconut, grapefruit, hazelnuts, cherries and other fruits are planted in the space. With this unmanned agricultural robot, the output has been greatly improved.

The time contrast in the jade pendant space is 365 times that of the outside. Now that nearly 10,000 people have migrated to the space, there will inevitably be a surplus of various crops and meat products. Thinking of this problem, Tianyi thought of compressed food.

Compressed food has high energy, small size, easy to carry, and is suitable for use in various environments such as tourism. So Tianyi discussed with the Hu sisters and started the plan to compress food.

Hu Yali said with a smile: "Now we have eight large ecological parks, and it is very cost-effective to sell finished products. We can develop some cost-effective products, and compressed food is a direction. Today's young people are enthusiastic about tourism and believe that there will be a good market for compressed food. ”

Hu Yafang nodded and said: "Compressed food is indeed a trend, but if it is the same variety as the market, it is difficult to reflect our advantages." We can write on taste and variety, and we can write on that. ”

"The compressed food we launched can be designed to be small in size, light in weight, high in nutrition, easy to eat, hunger-resistant, and prepared according to the customer's itinerary to provide customers with goods. Nutrition can meet the needs of the wild, easy to carry, and resistant to storage, these characteristics are what we need to solve. This product can be used to meet the physical needs of people working in the field. ”

"It can also be offered to families who can afford to be wealthy, and such products can be prepared even for ordinary families. In case of some accidents, such as earthquakes and floods, you can store some. ”

Tianyi listened to the two sisters of the Hu family and agreed with their own ideas. I was very happy and added: "In addition to compressed biscuits, we also launched compressed pastries, dried fruits, peach cakes, baked fruits, eight pieces, moon cakes, printed cakes, egg rolls, etc. You can also launch sugar, rice candy, cold cakes, etc. Varieties such as cold sorbets are easy to eat and save time. ”

"Another point is to compress the shelf life of food, which is generally 12-18 months on the market now. We can design a shelf life of 3-5 years, and although this will increase the cost, food is a strategic resource. This can serve as our strategic reserve once something happens. ”

At this time, Tianjia didn't know when he came over, and listened quietly when he heard the words of Tianyi and the others.

Finally, Tianjia added: "The production of compressed biscuits is very expensive because it requires a production machine for compression. But such machinery is rarely purchased on the market, and if it can be provided, such products are more abundant than military supplies. This is already up to the standard of military compressed food. In addition to the arsenal, there are very few civilian compressed biscuits that can be bought on the market.

Tianyi suddenly became interested, and hurriedly asked: "Yes, Tianjia is from a special forces, and you have the right to speak in this regard." How many pieces of military compressed biscuits are suitable for a meal?"

Tianjia replied: "In the general march, military compressed biscuits eat 62.5g ~ 125g at a time. It can meet the needs of normal people for one meal, and it is not advisable to eat too much. Because generally a piece of military compressed food is enough, if you take too much, it will cause indigestion. ”

"A piece of compressed food acts on 63 grams, and the calories are about 800-1000 kcal. Equivalent to two bowls of rice, or even higher than it. This is also the reason why compressed foods can quickly increase physical fitness. ”

Tianyi was like a hundred thousand whys, so he went on to ask: "Tianjia The army you knew before is suitable as a compression product for long-term reserves. What are the types of food, are there only compressed cakes?"

Tianjia smiled and said: "We are a special operations unit, and we generally need mixed individual rations that are high in calories and easy to carry. A big bag contains staple foods, meat, sugars, carbohydrates, and more, a bag of food rations for the day. It is divided into different combat missions and proportioned, and there are dozens of small packets in one can. ”

Tianjia added: "Now the compressed food is more abundant, and of course there will be a lot of canned food, pancakes, and ham. There is also a kind of fried noodles, which can be eaten directly in water for a long time. 5 kg of compressed biscuits, which can be eaten for half a year. ”

"5 kilograms of compressed biscuits, can you eat for half a year?" Tianyi's surprised mouth could be stuffed with eggs.

"The latest compressed dry food, 10 sachets per drum. Generally, there are two iron drums in a whole box. Navy soldiers are equipped with this compressed diet, and they are equipped with three staple foods. There are compressed dry food, dehydrated noodles, dehydrated rice.

"There are also new foods composed of canned luncheon meat, mixed mixed meat, and canned pork with sauce. In addition, there are pork egg rolls, refreshing mustard, instant solid drinks, ready-to-eat food, anti-fatigue cereal bars, and sausage fried rice. ”

"These products can achieve a high calorie of 5 kilocalories per gram in an emergency situation without fire or water. This new type of compressed food, 5 kg of individual field dry food, can provide a person with a minimum life support for half a year. Even 1 small package can support people for half a month, which is the minimum requirement for a special operations team. Tianjia said slowly.

Tianyi listened to the words of the two sisters of the Hu family and Tianjia, and lowered his head and thought: "It seems that Xu Lao still needs to invite several academicians, and these technical fields still need to find professionals." ”

At this time, the two sisters of the Hu family and Tianjia, these people chatted without a word. At this time, Yu Lao walked into the conference hall with Yin Xiao, Wang Tianran, Li Yongjian, Liu Baotong, and Lu Xinchen. Tianyi will compress the machinery and equipment of food, and Yu Lao consulted.

At this time, these mechanical experts each put forward their own suggestions. Yu Lao suggested: "The more advanced equipment for compressed food is the heat pump dryer. There are four components, heat exchanger (internal machine), flow restrictor, heat absorber (external unit, compressor and other devices) constitute a circulating system. ”

"The heat pump dryer uses the inverse Carnot principle to absorb the heat of the air and transfer it to the room, so as to increase the temperature of the drying room and cooperate with the corresponding equipment to realize the drying of materials. It has the advantages of low energy consumption, low environmental pollution, high drying quality and wide range of application. ”

"It's a problem with the equipment, and the equipment problem is solved. It's a question of how to package food after processing, how to improve shelf life, and how to open the packaging.

Tianjia raised a series of questions, and then Yu Lao wrote them down in a notebook, and then found a way to solve them when he went back.

Yin Xiao said slowly at this time: "For the packaging of compressed food, you can use fence technology and packaging technology. This technology can solve the problem that canned food is difficult to open. The insulation material used in self-heating cans, and the rehydration box used for dehydrated rice and dehydrated noodles. In order to meet the needs of floating, airdropping, etc., glass wool and foaming materials can be used. ”

"Canned packaging can be designed as flexible packaging, rigid packaging and semi-rigid packaging in between. To solve the problem of opening cans, you can use easy-open lid technology. For example, like the eight-treasure porridge pot technology, it just needs to solve the hardness aspect. ”

"We have now developed a new material that is resistant to sulfur and acids. The shelf life of the surface after coating can reach three to five years. The technique of adopting a two-piece tank consists of two parts: a bottom and a lid. Containing 3 kg of food, this can can be used as cooking utensils, which can be placed on a fire or placed on a steam table to heat and keep warm. Compressed food beef jerky has also been introduced, which is highly nutritious, easy to store and easy to carry. ”

Yin Lao said: "There are 16 flavors of compressed food: green onion, coconut, pepper and salt, meat floss, pineapple, lemon, etc., one of which contains meat. In addition, it has also launched dehydrated vegetables, fruit slices, instant noodles, beef jerky, dried fish, butcher shops, shrimp and other meat compressed foods, various fruits, nuts, fruit slices, beans, nuts, and vegetable products. Chinese herbal medicines, Chinese herbal decoction pieces, and other tablets and granular materials, 30 kinds of food, compressed food. ”

"The technology of two-piece cans can also be used as tableware, replacing dishes and bowls, improving the convenience of military food. At the same time, it is also a storage container. Rectangular flat cans with a shelf life of more than 3-5 years,"

Compressed foods are also equipped with a self-heating device, which can be rehydrated in cold water, also rehydrated in hot water, and can also be boiled. The product has launched four items: staple food series, non-staple food series, soup beverage series and canned rice porridge. There are three types of outer packaging, namely, edible packaging, water insulation and water vapor, and combination packaging.

The outer packaging is set up in two types: water insulation and water vapor, so the packaging material is relatively simple. The price is also relatively cheap, on the one hand, it can reduce the volume and quality of the package. Increase the edible portion of the whole set of foods. There are canned food, compressed dry food, seasonings, etc. The packaging used when these products are combined into meal foods or daily foods according to a certain nutritional composition is called combination packaging.

The outer packaging requires military food, which can withstand airdrops and umbrella drops, and can float on the water. A self-heating device is a flameless heater that can self-heat. This heater can heat the core temperature of canned food to about 60°C. In order to effectively improve the efficiency of the heating sheet, prevent heat loss, and prevent the temperature from burning the skin, it is necessary to use thermal insulation materials. This packaging material requires small size and good thermal insulation.

There are three Burgundy melons, Blancs and Pinot Grigis similar to those of the Loire Valley, and the three main white grape varieties grown here.

After the fruit was ripe, Professor Yu invented a picking robot. Like a toddler who doesn't want to spill the soup when he drinks it, the robot carefully picks it off and puts it in a small fruit basket after making sure that the raspberry in front of him is ripe, and the whole process lasts about a minute, but this robot can work continuously for forty-eight hours without stopping.

The robot is 1.8 meters tall and can be freely retracted, and can be extended up to 15 meters. The pincers use artificial intelligence to amplify the ripe fruit and then pick it. A single robot will be able to pick more than 25,000 fruits per day, much faster than the rate at which human workers can pick 15,000 fruits in eight hours a day.
