Chapter 231 Grain Processing, Rubber Tires, Telephones

Zhang Zhimu was very stimulated by Zhang Bingchen's sentence "human life is a matter of heaven", he felt that it was time to make up his mind to solve this problem, and the foundation of the kiln gang has become more and more perfect, and there are more and more means to solve the problem, "Bingchen is right, the matter of human life must be solved first." I'll straighten out the penicillin matter and I'll go back to you to look into it. ”

Zhang Bingchen also wanted to talk about smallpox, Zhang Zhimu said: "I won't say anything today, I promise the children to go home tonight to cook for them, and I can't break my promise." I'll talk about the rest tomorrow. ”

Zhang Bingchen and Qin Peng were stunned when they heard Zhang Zhimu's words, they didn't expect that a fairy-like person like Zhang Zhimu would go home to cook, and the two of them got up and walked out with Zhang Zhimu. Only Yang Yulin was left outside.

After sending Zhang Bingchen and Qin Peng away, Yang Yulin asked, "Why don't you go and see our house?" ”

Zhang Zhimu smiled bitterly and asked, "Do you think I have time this year?" Almost too busy? If I hadn't said I was going home to cook, I wouldn't have been able to get out of it now! ”

Yang Yulin had no choice but to sigh and say, "Only my people can help me in those houses." Everyone else is busy, as if no one of us is not busy. ”

Zhang Zhimu knew that the "my people" Yang Yulin said were actually the children of the eight businessmen in Zhangjiakou, and after they came to Yaogang, they had been taken care of by Yang Yulin personally, and Yang Yulin also regarded them as his own people.

Zhang Zhimu said: "You have to take care of the son of King Zhou." The few who came from Zhangjiakou went to school easily. The couple who gave birth to a child had to arrange a suitable job for them and a house for them. ”

Yang Yulin said: "Don't worry, I treat them as my own relatives, and they also treat me as relatives." They come to me no matter how big or small, and now they feel much more free than when they were in Zhangjiakou. If you let them go back and be young masters, they may not be able to do it. Pretty much all of my money was spent on them. ”

Zhang Zhimu said as he walked out: "You person, you make a list of the cost of this matter, just go to Mr. Lu to report the account, and rely on your own money." ”

When Zhang Zhimu returned home, Xiaoqing and Xiaohu were waiting a little anxiously. Seeing Zhang Zhimu's Xiaoqing, his eyes were a little moist and said to Zhang Zhimu: "I thought you were busy today and forgot to go home to cook and eat?" ”

"Gee, it's been so busy today. But no matter how busy you are, you have to keep your word, and I promised to come back to cook and I will definitely come back. Zhang Zhimu said.

Huang Yukun heard the voice and came out and said, "If you're too busy, I'll take them to the cafeteria for a bite." ”

"What's the line? Xiaoqing and Xiaohu are willing to eat what I made, this can't be helped, is it Xiaoqing and Xiaohu. He said as he looked at the contents of the kitchen.

"Yes, we are all willing to eat what my uncle made." Xiaoqing and Xiaohu should know that they cooperated.

Huang Yukun pointed to the fish in the barrel and said, "This is what they caught today, I asked them to send two, and they are still alive." ”

Xiaohu said: "I also want to eat steamed fish and fish soup. ”

Zhang Zhimu saw that there was still a piece of fresh mutton in the kitchen and said, "Steamed fish is our repertoire, and we must have it." But how about we change the way we make the fish soup today? ”

As soon as Xiaoqing heard that there was a new method, he said, "Okay, let's change the method." ”

Xiaohu asked with some hesitation: "Uncle, is the new method delicious?" ”

Zhang Zhimu asked: "Is there anything bad for my uncle to make?" ”

Xiaohu was also happy and said, "Then change the approach." ”

Zhang Zhimu's method this time is actually similar to making fish soup before, which is to put the freshly slaughtered fish in the pot with cold water, boil the pot for a while, put the mutton slices into the pot, and then season it after boiling the pot, and put some vinegar and pepper.

Of course, this dish will be served last. Zhang Zhimu quarreled with a few more ingredients that Xiaoqing and Xiaohu liked to eat, and mixed a small cold dish.

Xiaoqing and Xiaohu have been accompanying Zhang Zhimu in the kitchen, watching Zhang Zhimu busy. Zhang Zhimu also knew that the two children wanted to stay with him for a while, because Zhang Zhimu was too busy now and had very little time with them. Zhang Zhimu also deliberately assigned tasks to their sister and brother, one would pick up onions and one would pick garlic. The young lady and brother saw that there was a job, and they worked very hard.

Huang Yukun watched the three of them busy in the kitchen, his eyes a little moist. Xiaoqing and Xiaohu feel like the happiest people in the world now, and they know that there is one of the strongest people who spoils them.

The meal was served, and Xiaoqing said before he could eat: "Oops, it smells good." ”

Xiaohu is a bit of a gourmet, he didn't speak, he scooped a spoonful of soup with a spoon and slowly put it in his mouth, tasted it, scooped another spoonful and drank it, and then said: "Uncle, today's soup is indeed different from before." Very delicious! ”

Zhang Zhimu and Huang Yukun laughed at the same time, and Huang Yukun said: "Look at it, you are used to the two of them, but don't eat them in the future." ”

Zhang Zhimu said: "To be honest, it's not easy to eat. Now, there are really not many of us Yaogang people who can eat like Xiaoqing and Xiaohu. ”

Xiaoqing said: "The same fish soup, why is it not as delicious as my uncle's cooking?" ”

Huang Yukun said: "The fish soup in your school is made from frozen fish in the cold storage, can it be compared with live fish?" ”

Xiaoqing pouted and said, "It's hard to drink anyway, but my classmates still say it's delicious." ”

Huang Yukun said: "You are all letting your uncle you, and you forgot to drink wild vegetables, and the paste is very fragrant." ”

Xiaoqing heard Huang Yukun say this, stuck out his tongue at Zhang Zhimu, and didn't dare to speak again.

Zhang Zhimu said: "You should organize a fishing team to fish in the West Mountain bubble in the north." Build a few houses next to the bubbles, we have more people now, this is also a logistical support, and we don't need to spend money to buy fresh live fish. ”

"I'll tell Sister-in-law Xu tomorrow and let her arrange it." Huang Yukun said.

"Don't tell her, it's inconvenient, I'll just let Yang Yulin notify her. If only there was a telephone. Zhang Zhimu said.

Xiaoqing asked, "What is a phone call?" Can electricity still talk? ”

Zhang Zhimu said: "Of course, electricity can speak, and electricity can not only speak, but also transmit people's images. What are you doing at school in the future, I can see it in the office? ”

Xiaoqing asked, "Then do I see you too?" ”

Zhang Zhimu said: "Of course you can. But things have to be slow. ”

"When will I have a phone, can I play?" Xiaohu remembered it.

Zhang Zhimu touched Xiaohu's head and said, "I'll start arranging for them to make phone calls tomorrow, and I'll be the first to let Xiaohu play." ”

Lying in bed at night, Zhang Zhimu said to Huang Yukun: "Tomorrow afternoon's meeting is very important, if you can move, go and listen to it!" ”

"What's so important, why don't you fly me?" Huang Yukun asked.

Zhang Zhimu said: "We must be prepared to face Li Zicheng directly. When I came back from Tongguan, I heard that the imperial court forced Sun Chuanting to go south to fight Li Zicheng, and if the battle was defeated, Tongguan would be lost. After the loss of Tongguan, it was difficult for Shanxi to hold on to the current situation. We must be prepared to hold the kiln post and then counterattack and occupy the whole of Shanxi. ”

Huang Yukun said: "I knew that your heart was bigger than the sky, and sooner or later there would be such a day." Now that we have silver and food, we can recruit more men and horses to help the imperial court defend Shanxi. ”

Zhang Zhimu replied: "If we recruit people now, it will be a rebellion." Not only Li Zicheng wants to deal with us, but the imperial court will also deal with us. Then we will die without a place to bury. If we take back the city from Li Zicheng, the imperial court will not say anything. As long as we don't fall out with the imperial court, the imperial court will feel that these places are better in our hands than in the hands of Li Zicheng. ”

Huang Yukun sighed and said, "Alas! I just want to live a few days of peace, just like this, how good it is, every day without worrying about food and clothing. ”

Zhang Zhimu hugged Huang Yukun and said, "It would be good if we occupied Shanxi." At that time, I will take the initiative and live without looking at anyone. Survive this time, and good days are still to come. ”

Huang Yukun suddenly remembered something and asked Zhang Zhimu: "Alas! I said that if you can make this machine and that machine, you can't make a machine for grinding rice and flour? Those of us are tired of grinding rice and flour every day. ”

Zhang Zhimu said: "Oh, you have mentioned a good business, and the quality of the flour we eat now is too poor." We can make a flour mill to process wheat into different grades of flour, and with this alone, we can sell the same flour for a lot of silver. Besides, the bran we use to make MSG must also be properly separated by equipment. As for the rice mill you mentioned, it's much easier. Your reminder is so good, I'll arrange for Li Yunhe and them to do this tomorrow. It seems that she is still a good wife and wise! ”

"You're just sweet-mouthed!" Huang Yukun pinched Zhang Zhimu's ear and said.

As soon as he arrived at the office in the morning, Zhang Zhimu asked Yang Yulin to send someone to find Li Yunhe, Lu Qi, and Yang Chang.

As soon as Li Yunhe entered the door, he said: "Look at it, I haven't finished explaining what you finished talking about yesterday, and today you are here again." ”

Zhang Zhimu said: "We have developed to this point, so let's do a lot of things together, the sooner the better." The first thing is to bring Qingfengzi and his few graphite people over and ask them to set up a new materials laboratory. First of all, it is necessary to carry out the vulcanization test of rubber, and strive to make rubber tires as soon as possible. In this case, your steel spring carriage can be reeled with rubber. ”

After listening to this, Li Yunhe laughed and said, "Is it the soft rubber that makes the wheel?" ”

Zhang Zhimu knew that Li Yunhe couldn't accept the use of rubber tires all of a sudden. He took out a pen and drew a diagram of the structure of a tire with inner and outer tubes, and then said, "Every time your hard wheel is stressed, what point does the wheel contact with the road surface, right?" ”

Li Yunhe nodded and said, "That's right." ”

Zhang Zhimu said: "Our rubber tire, if the inner tube is full of gas, the pressure at any point will be distributed to the whole tire through the principle of uniform pressure conduction, that is to say, the rubber wheel is the whole tire at the same time at any time, and the load on the tire as a whole is borne as a whole." Such tires not only have cushioning elasticity, but also have a load-bearing capacity far greater than your current steel wheels. ”

Li Yunhe looked at the drawings and nodded, "The outer tires of this wheel must be hard enough, otherwise they will wear out soon." ”

Zhang Zhimu listened to Li Yunhe's point all of a sudden, and was very happy about Li Yunhe's habit of using his brain when he encountered trouble, and said: "Let them come specifically to work on this thing, that is, to add something to the rubber and improve the characteristics of the rubber." Not only to strengthen the strength, but also to resist aging and many other things. ”

"Okay, I'll wait for Qingfengzi's people to come, and then I'll match them with a few more people, and let them specialize in rubber and graphite." Li Yunhe said.

Lu Qi came in, and after Zhang Zhimu poured him tea, he said, "I invite you and Li Yunhe to come over today, because I have a task to give to you." It took a lot of time for Lu Qi's people to finish building the weaving machine, although it took a lot of effort, but they also brought out a lot of people, I don't think you can use so many people to build a sewing machine. You can take out some people to make rice mills and flour grinders. ”

Lu Qi said: "Do you still need me for this?" Wouldn't it be enough to bring up the stone mill and grinder with an electric motor? ”

Li Yunhe smiled beside him and said, "Hehe, if it were so simple, I wouldn't have called you here." ”

In the previous life, when military products were sluggish, Zhang Zhimu and his team once carried out projects for a grain depot and a large grain processing plant, where they came into contact with grain processing equipment, and they still had some impressions of those equipment. Zhang Zhimu said: "Grain processing is a promising thing. Rice processing is simpler than wheat processing, as long as the husk is cleaned and the rice is not broken too much. The more difficult thing is wheat processing. ”

Zhang Zhimu first relied on the impression of his memory to draw a structural diagram of the rice milling machine for Lu Qi. This rice mill is mainly composed of fixed wrench, tightening nut wrench, brush, hopper, grinding wheel, wire brush, etc.

Its principle is that when the rice flows into the whitening chamber from the hopper, due to the internal pressure of thallium and the promotion of mechanical force, the rice is squeezed in the whitening chamber, and after self-friction and the mutual friction between the brown rice and the grinding wheel, the cortex of the brown rice can be quickly removed, and then the determined grinding time is adjusted to make the milled rice reach the measured grade of whiteness.

Li Yunhe and Lu Qi probably understood the structure of this rice mill at a glance.

Lu Qi said: "This rice mill is indeed much faster than grinding with a mill, and I don't think it's difficult." ”

Zhang Zhimu said: "Some of the difficulties are the flour grinder. The process of wheat grinding into flour includes removing impurities, moistening wheat, peeling (drawing), grinding, screening, adding, clearing and packaging. Each of these processes requires some effort on your part to experiment and study. The milling process of wheat is also called the flour road, generally there are four systems of grinding, sifting, cleaning and brushing, each system generally has a lot of processes composed of roller mills and sieves, grinding and sieving in order, and gradually grinding wheat into flour. By adjusting the process, we can produce different qualities of flour. Unlike nowadays the flour I eat is all whole. The difficulty lies in the roller mill. ”

Zhang Zhimu gave a general introduction to the principle of the roller mill, and he didn't know anything too fine.

The roller mill is composed of two grinding rollers that move in opposite directions at different speeds, and the wheat is crushed by the relative movement of the grinding rollers and the extrusion and shearing of the grinding teeth between the two rollers. Grinding rollers, toothed rollers and smooth rollers.

The toothed roller is a grinding tooth that is cut with a scraper on a cylindrical surface and is used to crush grain and peel the germ on the bran flakes.

The smooth roller is sandblasted after polishing to obtain a slightly rough surface for grinding high-grade flour systems.

After introducing these, Zhang Zhimu said: "I can only introduce these general situations to you, and you have to form a group to continuously experiment and improve the details." My request is to get the bran skin out for me, and I want to produce the bran skin for MSG. ”

After listening to this, Li Yunhe said: "It seems that the task given to us by Mr. Zhang is becoming more and more complicated. ”

Lu Qi said: "I think this matter is a little troublesome, but it won't be too difficult." I think that after they finished building the loom, they didn't think it was difficult to do anything. ”

Li Yunhe saw that Lu Qi was very confident, and said: "In this way, I will send you a few more people, and you will also draw out two people to set up a team, and you will personally be responsible for leading the flour machine as soon as possible." I'd like to taste MSG as soon as possible. ”

"Okay, let's do it." Lu Qi nodded and said.

Lu Qi saw that his affairs were almost over, and there was still Yang Chang in the house, knowing that Zhang Zhimu must have something to do, so he left.

At this time, there were Li Yunhe and Li Di in the house, Zhang Zhimu got up and moved his legs and feet, sat down and drank a little tea, felt a little better in spirit, and asked Yang Chang: "Yang Chang, you said that we are now communicating with people, which way is the most convenient?" ”

Listening to Zhang Zhimu's question, Li Dile said: "Of course, it is most convenient to speak, do you still need to talk about it?" ”

Zhang Zhimu said: "That is to say, if we can communicate through speech, it is much better than using telegraphs, right?" ”

Yang Chang snorted and didn't answer, he knew that Zhang Zhimu must have something to say.

Zhang Zhimu said: "I came to you this time to study and solve the problem of using wires to make calls. ”

Yang Chang and Li Di looked at Zhang Zhimu with wide eyes at the same time, they were shocked by Zhang Zhimu's statement, if this was said by someone else, they would definitely laugh, but this is what Zhang Zhimu said, and Zhang Zhimu would never joke about such a thing.

Zhang Zhimu looked at them a little funny, and asked, "What are you staring at with big eyes?" Isn't it just a matter of talking on the phone? In the future, you will have to go through the image and see the real person, and you still don't want to stare out your eyes? ”

Yang Chang asked: "Mr. Zhang, is what you said true?" ”

Zhang Zhimu did not answer this question, and said: "In fact, the sound of our speech is a vibration of the air. If we convert the vibration of the air into the fluctuation of the electric current and transmit it to a distant place, and then convert the fluctuation of the electric current into the vibration of the air in the distance, will the sound be transmitted to the distant place? ”

After listening to this, Yang Chang nodded slowly and said, "The truth is like this, but..."

Without waiting for him to finish, Zhang Zhimu drew a circuit diagram with a voltage on both sides of the resistor, and said: "Look, this voltage is certain, if the resistance value of this resistance changes, according to Ohm's law, will the current also change?" ”

Yang Chang nodded and said, "Yes."

"I'm telling you there's a thing where the value of a resistor changes with the sound." Zhang Zhimu continued: "When the people who are engaged in graphite come, we ask them to squeeze out some small graphite particles for us, put these graphite particles in a small box, and after the two ends are energized, its resistance value will change with the change of pressure." If we cover the carbon crystal with a thin film, the vibrational pressure generated by our voice will change the resistance of the carbon crystal, and the current will also change. ”

Yang Chang understood a little this time, and asked, "Then how can you change the current back into a sound?" ”

Zhang Zhimu said: "There are many ways to do this, and we will use the simplest one now." We use a U-shaped battery iron, put a coil in the middle, if the current flowing through the coil changes, the coil produces a change electromagnetic field, under the action of magnetic force, it will vibrate, and this coil will drive a diaphragm to make a sound. ”

Yang Chang thought for a while and said, "Mr. Zhang, it stands to reason that this principle is not too difficult to understand, but I don't know how it will work?" ”

Zhang Zhimu said: "You do some experiments first, and then study practical things when you are mature." Now this is your main task. ”

After Yang Chang took a few sketches drawn by Zhang Zhimu and left, Li Yunhe asked Zhang Zhimu: "I have too many things to do, just hold the afternoon meeting with your leaders, why do you want me to participate?" ”

Zhang Zhimu replied very seriously: "This year's afternoon meeting will be a meeting that will decide the life and death of our kiln gang people, and you must go to it." ”
