Chapter 1342 Canned Food
Chu Yun held a cuboid-like metal box in his hand, but it was very light, and it seemed that just squeezing it hard would dent the metal box.He is too familiar with this thing.

Nelson's face looked a little weird, and he tapped the cuboid metal box with his fingers: "It sounds like tinplate, but I don't know what it's used for?"

"We plated a layer of tin on the iron sheet, and after a series of processes, we have tinplate, which is a tin plate. We use this tinplate to produce tin cans for food preservation. A skilled worker can produce 60 tinplate cans." The general office replied.

"You mean to put food in such an iron box?! Will the food not spoil?" Nelson was surprised.

The general office said: "I only realized that the main cause of food spoilage is the growth and reproduction of microorganisms after I opened a canning factory. Bacteria effect, prolonging the shelf life of food. Please come with me.”

They saw the technology at the heart of the cannery—the airtight autoclave.This kind of large pot has complicated exhaust valves and detection instruments, which are precise to a certain extent.

"Steam is the gaseous form of water, it's non-toxic, easy to make, and relatively easy to control, and the pressure of steam in a retort can reach an astounding number. I've heard them say that the higher the pressure, the higher the boiling point of water, The temperature inside can reach 132 degrees Celsius to 134 degrees Celsius. I don’t know the specific principles. Xiaguan needs to manage many factories in the arsenal, and each arsenal has many machines. Their structures are complex. In fact, only their designers and Only the craftsmen in charge of maintenance can fully understand the principles." The general office replied.

His job is to coordinate the division of labor and cooperation in the arsenal, and to achieve the goals above, he only needs to know the functions of certain instruments, and it is not necessary and impossible to know the details of all the machines and equipment.

Chu Yun also has no idea how the so-called pressure sterilizer is used, only that it has a similar principle to high-temperature sterilization.

"Tinplate can mouths have unimaginable value, especially for military use, which can alleviate the problem of food shortage and rapid corruption to some extent. Compared with artillery, this thing may be more useful to your Admiralty. We can make fruit cans , canned fish and other food, to improve the poor diet of naval soldiers, and to avoid diseases caused by lack of fresh food when they are far away.” Chu Yun shook the tinplate can in his hand.

At this time, the fleet of the Kyushu Army can be said to be the first, and the production of more powerful artillery is just icing on the cake, and the combat effectiveness of the fleet is not only weapons, but also the lives of naval soldiers.Food is logistics. How to make sailors eat fresh food has been a difficult problem for thousands of years.

"Such cans can keep food from rotting for several months if the seal is good, and some foods may even be preserved for up to a year." Nelson learned that tinplate cans not only use incredible After steam sterilization technology and sealing technology, he was deeply aware of the future of food cans.

For sailors who cross the ocean, it is a blessing to be able to eat a little fresher food after drifting on the ocean for a month or two!

"After conducting the experiment, we will take the lead in producing a batch of canned fish and canned yellow peaches and deliver them to the Ministry of the Navy," said the director of the canning factory.

Hokkaido is a good place to set up a fish canning factory.Chu Yun thought of Hokkaido Prefecture in the Eastern Province, which is adjacent to the Hokkaido Fishing Ground, one of the four largest fishing grounds in the world. It happened to be able to build a canning factory when the Hokkaido Fishing Ground was being developed, and sell canned fish to the inland or the military.

"Although large-caliber artillery is very important, the training and care of soldiers must not be exhausted. No matter how powerful a weapon is, it is also a human being who uses it. We also need to ensure that ordinary naval soldiers have the space to be promoted to lieutenants. Soldiers Fight hard. And the conflict between operational officers and technical officers, the development of active duty officers..."

"I will organize the officers of each fleet to return to Tianjin Wei in turn for advanced training in the Navy Lecture Hall. They need to master the basic knowledge of iron-clad ships. Only the Fourth Fleet is currently in Europe, and it is undoubtedly necessary to arrange their officers to go to the Navy Lecture Hall for further training. It's a difficult thing."

"In the future, let the Fourth Fleet formulate a training plan within their own fleet, and regularly organize a group of naval officers to return to their homeland for study and assessment."

Chu Yun and Nelson walked out of the cannery while talking.

They still don't know that the Fourth Fleet is giving them a face to extort millions of taels of silver in the Mediterranean Sea. If the Fourth Fleet hand over the extorted money, building a Daqin-class steam ironclad ship is really not a big deal .

"Master, do you want to inspect other finished products in our arsenal?" the general office asked cautiously.

He dared not intervene in a discussion of the naval fleet.

"No need, this time I have seen what I want to see. Your arsenal is running well, and it is expected to complete the production target this year. You just need to continue to produce according to the instructions of the military department. The logistics department will not let the arsenal There is a shortage of funds," Chu Yun said.

"Master, please go slowly." The general office sent it to the door, seeing that Chu Yun's words had affirmative meaning for Tianjin Guard Factory, he couldn't help but secretly smug.

"Master, if you just want to see the new cannons and food cans, you don't have to come in person, you just need to have the food cans delivered to the capital." Nelson said after leaving the arsenal.

"Guess how I came to Tianjin Wei?"

"Steam locomotive?"

"No, I came here in a horse-drawn carriage through the official road. The third phase of the road from Beijing to Tianjinwei has been completed. This time I specially took a horse-drawn carriage from the capital to here to verify whether the third phase of the project has cut corners. Whether the construction is in line with my vision."

"How is the result?"

"The fact that I can stand here calmly shows that I am very satisfied with this section of the road."

Chu Yun saw the haze in the sky over Tianjin Wei, and it was probably going to snow in the cold winter.

"Would you like to have a glass of wine with me?" asked Nelson, whose temples were already graying.

Chu Yun originally planned to accept it, but Yu Cheng, the chief guard, received a telegram and forwarded it to Chu Yun.

"I'm afraid I won't be able to drink happily this time. Next time, I have to hurry back to the capital."

After reading the telegram, Chu Yun showed a trace of nervousness and anticipation.

The content of the telegram is very simple, Da Yuer is about to give birth.
