The study of the detoxification treatment of cotton oil is relatively simple.
The craftsmanship is improved on the basis of tradition.
The hulling stage is all manual, milled with a mill, and then screened.
Before the general stir-frying, an extra process of steaming the cottonseed embryo with high moisture is added.
After steaming, add a certain amount of lime and stir-fry to make oil cakes.
Squeeze out the crude oil.
Filter, alkali and heating to separate the soap feet.
After getting the clear oil, add water and warm it and wash it several times.
The cottonseed oil becomes clear, without much smell and odor.
The general cotton oil is cloudy with a distinct odor.
So the rich don't eat it.
However, the refined cottonseed oil looks good, the gossypol detoxification is very clean, and the safety is still guaranteed.
The market is difficult to say, because there is a habit of useful oil, the rich do not buy it, and the poor have extremely poor purchasing power.
Cottonseed husks are directly used for cattle, cottonseed cake is used as fertilizer, soap feet support soap, and sewage is stored to make farm fertilizer. finally met Zhang Chun's environmental requirements, and there was really not much waste.
The chemical experiment work in the laboratory was mainly completed by Zhou Xinlai, and it went very smoothly.
After the completion of the theoretical research work of detoxification, it is a problem of the design of production equipment and production process.
Wang Zili and his students majoring in mechanical and electrical engineering originally wanted to design a set of equipment by themselves, but it was too difficult.
Behind the ginning plant, an oil mill was initially built using the traditional pressing process, but it was only for research purposes.
After the oil mill was built, it was not much different from the general oil mill, except for the addition of a huge steamer.
The workers used long-term workers invited by Yunlong Town.
Each process is separated, and eight orphans in the Cotton Oil Research Institute are in charge of each process.
The Zhang family's oil mill started, and half of the income from the oil mill was given to Wang Zili to continue his research, in addition to paying the workers' wages.
The Wu family in Qinghe had a direct monopoly on the cotton oil and soap produced by the Zhang family.
These things were shipped directly to Hankow.
You must know that this is the soap of the times, and it has become a foreign soap, which is very expensive.
It's just that the yield is too low, and the process continues to improve.
In the Cotton Oil Research Institute, Zhou Xin took the chemistry students to continue the improvement of the cotton oil process.
Gossypol extraction is also done by Zhou Xin, but it is still being tested, and it is not possible to do animal experiments with gossypol alone for the time being, but the oil squeezed by the two methods is very easy.
Comparative tests are done in the clinic.
The girls in the hospital refused to feed the guinea pigs they bought from Hankow, they were only responsible for observing and recording the feeding by the barbarian girls of the Agricultural Research Institute.
Wang Zili took three young men, plus He Jun, who did septic tank environmental research at the Agricultural Research Institute, and began to study sewage treatment.
In fact, it is the study of the living environment and population reproduction of biogas digester organisms and bacteria, and by the way, the taxonomy and environmental research in the farm compost are also done.
Because Wang Zili wanted to improve the machinery and equipment for oil extraction, rather than adopting this primitive traditional pressing process, he planned to invite a few mechanics from the machinery manufacturing of the cave to come and assist in the research.
Of course, Zhang Chun knew the importance of machinery, in the past, it was because he didn't have this ability and demand, but now that he has it, he naturally has to get it together, otherwise he can't call out the students of the engineering school with Hu Dengping's two knives.
Gu Ming was even more anxious than Zhang Chun, but Gu Ming was thinking about military manufacturing.
Zhang Chun just mentioned it, and Gu Ming quickly got two mechanics from the Jiangnan Shipyard through his family relationship, and asked Zhang Yang to invite a senior technician from the Hanyang Gun Factory named Liu Guangli to come over, and at the same time brought over some mechanical processing equipment from the Hanyang Gun Factory.
Turning, drilling, milling, planing, grinding and a complete set of measuring instruments are available, as well as a batch of steel and ingots.
This year, the Hanyang Gun Factory suffered a flood, and a batch of new equipment was replaced, so the old equipment was eliminated.
Wu Sicheng had some business connections with the gun factory, so most of the small and sophisticated equipment he made was usable for both manual and steam power transmission.
Wu Sicheng said that you don't open a factory, you don't have a large generator and no steam engine, these things are enough.
Zhang Chun is quite satisfied with these equipment, because he attaches importance to people, as long as there are talents, the equipment will always be slowly made.
Gu Ming's ambition was **.
On the surface, Gu Ming seems to cooperate with Wang Zili to make a set of advanced pressing equipment, but no matter how Zhang Chun looks at it, he has the consciousness of making guns by himself.
Even the kiln built in Luyuan Mountain has changed, and there are one or two more blacksmiths, saying that they want to build their own farming tools.
But what do you do when you build your own farming tools and build an earthen stove for making iron?

Because of the good weather in recent years, the planting area and output of Zhangjialing have continued to increase, and the grocery store and grain and oil store at Nanzhangcun Wharf have actually become the only place where the mountain people can change their grain in the open and honest way.
Therefore, in addition to his own consumption every year, there is also an income of several thousand taels of silver, which can support Gu Ming to toss so much, so Zhang Chun has no objection.
But whether it is Liu Guangli, Wang Zili and Zhou Xin, they can't just engage in research, they all have to teach students.
Since he wants to teach students, Zhang Chundu requires a high level.
Zhang Chun doesn't have that much professional knowledge, but he has the vision, and he still has the equipment vision of the top research institute in later generations.
Every time, they can force Wang Zili, and they are in a cold sweat.
Therefore, after coming to Mengxuetang, I worked harder than my previous studies and research.
Liu Guangli studied in Germany and has the rigor of a German.
But the first thing he faced was Zhang Chun's dislike for the low precision of these machines and equipment, and rejected their proposal to buy a steam engine.
"We don't have the ability to make big things, small things are still okay, you improve your own tools first, and then talk about other things.
Also, the health center has a generator, but it's too noisy in the school, so let's see if you can improve the mill's waterwheel and let it generate electricity.
The generator of the health center will be given to you, and you will see if you will dismantle the research, or make your own internal combustion engine, or electric motor.
In addition, the engine or generator can not only fuel oil, but also gas.
Mr.
Wang is now working on biogas, and you can try to build gas turbines.
I'll draw a sketch for you, in fact, it's the same as a watermill and a windmill.
You'll see by looking at it.
In addition, you can improve the textile machine of the textile mill to be efficient and meet our textile process needs. ” Zhang Chun directly delayed Gu Ming's ** to build guns, but the proposed projects are all difficult, and they are by no means as simple as Zhang Chun's mouth said.
Because of Zhang Chun's request, Wang Zili divided the Oil Research Institute into two and changed it to the Chemical Research Institute and the Seiko Institute, positioning machinery manufacturing as fine machining.
When Zhang Chun left, he said: "You have finely processed machinery and equipment, and you can help the Self-Defense Forces repair guns and sharpen knives without cutting wood." ” Gu Ming, Liu Guangli and the others laughed when they heard it.
Zhang Chun said with a smile: "I am here in the school, to teach students well, research is the most important thing, fine and standardized is a must, otherwise it will not be good to teach students."
Talents are cultivated by you, tools are made by yourself, and when the time comes, you can make whatever you want. ” A few people were happy.
Relative to radical in education and research.
Gu Ming always felt that Zhang Chun was too conservative in his approach to the revolution.
Gu Ming and Yuan Dingguo were so suppressed that they found Zhang Chun and said that Zhang Chun was too conservative and did not dare to revolutionize.
"The two gentlemen should not think about the revolution for the time being.
In fact, all these things I do are revolutionary.
Electricity will change the world, and biogas can solve the energy problem.
Any technological improvement will bring about a revolution in society.
The reason why the West is now stronger than us is because they completed the Industrial Revolution.
I know you want to build guns, but technology is first and foremost for our lives and production.
The second is to improve weapons and equipment, and it is necessary to improve them in an orderly and gradual manner.
This is a systematic engineering problem.
Lord Jang Zhidong's Hanyang Arsenal should be considered very advanced.
But what benefits did the common people get?
The common people are poor, the common people are backward, no matter how advanced the weapons are, people will not be able to use them, and no matter how small the war, there is no economic strength to support it, this is the consequence of quick success and quick profit. ” "Isn't the imperial court good enough to be overthrown?"
Zhang Chun thought for a while and said, "**." ” Zhang Chun stretched out his hand to stop Gu Ming's words: "You listen to me."
However, the Qing Dynasty was not as good as the townships, and the reason why the common people were so miserable was because the imperial court allowed land annexation and exploitation by the landlords.
But don't forget that it is the landlord class, including you and me, who really makes the common people suffer.
Are these things I did in Zhangjialing cleared?
He didn't care, it was not the court that he was afraid of, but the gentry.
That's the fundamental. ” I saw two people bowing their heads in contemplation.
Zhang Chun continued: "I don't believe Mr.
Liang, I don't believe Mr.
Sun.

Why?
Because neither of them has solved the problem fundamentally, they will still be reduced to the gentry class and become exploiters.
The people are suffering and the people are suffering, because the people who are fighting are the exploiting strata, and the common people are just their tools. ” Yuan Dinghua is still thinking.
Gu Ming had already realized his problem, sighed and said, "Who doesn't want to do it."
The young master is good to the people, but what about the young master a hundred years later?
We're going to be 100 years from now.
It will always be reduced to the gentry class. ” Zhang Chun smiled: "Maybe, but I don't want to become a tool for them to compete for power now."
A good system and a good method are not something that we come up with at the moment, but we have slowly explored them in practice.
That's why I attach so much importance to education, and I want everyone to be literate and understand the truth, and be able to explore slowly through practice.
Hope is always in the next generation. ” Zhang Chun said what he said from his heart.
If you want to talk about high technology, Zhang Chun can make a bunch of them himself, but does it matter?
Important, but even more important, is the ability to develop students' ability to explore in the dark.
Cultivate students' ability to seek truth and be pragmatic.
So Zhang Chun would rather let them explore slowly, and he was just a guide.
