The design principle of the box is very simple. The bottom is iron. It is the same as the principle of the pot. It is used to be heated. The iron frame inside is heat-conducting, which introduces the heat absorbed from the bottom into the internal circulation relatively quickly.

As for the use of wood and a large amount of cotton and linen, it is the insulation measure under the original method, which is very critical, and even the first key.

As for temperature control, only manual intervention is allowed.

Zhao Ping'an trained a group of graduate students to do this. Compared with others, they were the first batch of technicians in the agricultural and animal husbandry industry in the Song Dynasty.

Speaking of later generations, in the era before the smart rice cooker was available, don’t laugh. Even cooking was a technical job. It is necessary to study where the heat should be stopped and how long it should be stopped before heating.

Therefore, when this first generation of graduate students finds a mature and useful temperature control method, it will be simple in the future. Workers can recite mantras such as "burn one and two, and then burn two and five". By following the table, the temperature of the incubator can be maintained at a range that the chicks can produce.

Of course, there will be different technical advantages and disadvantages of each person. So those with high hatching rates will be rated as advanced, rewarded, and shared technical experience. Each group will conduct technical competitions.

This is a certain extent a variant interpretation of evolution theory, so the research institutes can quickly dig up efficiency to the extreme under the framework of Zhao Ping'an, for example, the current feed is.

“Custom stove is here.”

The stove suitable for boxes and heating rooms is finally here.

A group of graduate students couldn't wait to squeeze in.

"You guys are so rude!"

When he saw that the magistrate was squeezed to the back, his official hat was squeezed to the ground, and he was stained with some chicken poop.

The students couldn't help but laugh.

Zhao Ping'an felt that they were too much, so he had to act awkwardly and said, "Be arrogant and let the county master leave first. Sir, I think you understand this etiquette?"

"Forehead……"

After looking at it, there was no need to wear a hat inside. Lu Shijie laughed dryly, handed the hat to Song Aisi, and walked in with his hands behind his back.

Then the rest followed...

"Sir, how long does it take to burn?"

A student asked after the stove caught fire.

Zhao Ping'an shook his head and said, "I don't know. Remember to tell me after you research it."

“…”

Everyone looked at each other.

Uncle Lu Shijie leaned closer and whispered, "Is it really OK? Did you deliberately set up a bureau to deceive me in order to cheat the county's funds?"

Zhao Ping'an looked strange, "It's certain that it's OK, and the funds really depend on fraud. There is no secret, it's just a process of trial and error and summary. For example, this time, burn three breaths, and excessive heating causes the egg to be wasted, so next time you have to breathe two breaths, and then make repeated adjustments. The funds are used to buy eggs and firewood, and then burn them constantly until the scholar, I hatch life on behalf of the old hen."

A few moments.

Zhao Ping'an molded the iron skeleton inside and said, "Okay, yes, the heat conductivity of the iron is not ideal. If you stop enough, you will have too much. You need to make a good measurement in advance. You try again and again according to this principle."

Waited for a few more moments.

Zhao Ping'an said: "Okay, heat it. When you feel it is cold, the chicks will definitely be in an environment that is not suitable for life to be bred for a while. Maybe it will get cold. You still have to take the pre-test. Don't always wait for me to call me. Learn from one example and use different methods to test the two groups."

So the graduate students carried the boxes away again.

The clever ghost Zhou Qing complained: "Sir, if you continue like this all night, at least two people will have to wait for you."

Zhao Ping'an said: "How many chicks are there now?"

"One Hundred and Sixty Months! I can't even buy it, I'm really crazy!"

This time it was Lu Shijie's excited answer.

Zhao Ping'an nodded and said, "That's good. If this is the case, as long as the shell rate is 50, six people will be asked to work in three shifts, and give full overtime and high temperature subsidies. We have made a lot of money. This is simply a huge profit. In addition to the improvement of productivity, my education office will soon become the first place to solve employment. Do you believe it?"

"Borrow a step to speak!"

Hearing this, Lu Shijie could no longer hold on to the air, and he pulled Zhao Pingan to the corner, "I can get 300 trump cards after being squeezed out. If you like it, you will take it away. I know, even if you use the county school territory, I can't do anything about you, but if you have a conscience..."

Zhao Ping'an interrupted: "Then it is the starting capital of 300 guan. The industry is the county government industry. I am responsible for the operation and find subsequent funds to pay their interest, but it is not counted as shares. Scholar, I insist that this is a state-owned asset, but you are not allowed to use glass during your term of office. It must continue to be under the jurisdiction of the Education Office?"

"!"

Lu Shijie wondered if he heard it wrong, "You smart guy is so good? If you don't talk about any conditions, what's the difference between this and giving it for free?"

Zhao Ping'an smiled and said, "There is a difference. First, I repay the county master's kindness for his kindness. Second, I want to do this and let those familiar people in the street eat more nutritious food. Third, after doing this, it will be your political achievements, but it will also be my resume and people's expectations. It will definitely not harm my life. By the way, when the county master is free, write more "Letter to the Ministry of Revenue" and other hypes to the court, and mention my name a few times by the way. This is the additional condition."

"..." This is of course too simple.

So Lu Shijie was skeptical and looked at him for a long time and said, "Then, this county will treat you as serious, it's not someone who forces you."

Zhao Ping'an waved his hand and said, "Don't force it, let's leave it alone. I may lose this time. Once I lose, the county magistrate's money, political achievements, and my reputation will bet together."

Lu Shijie said embarrassedly, "You are not that lucky, are you so many useless scholars, but you met me and were praised by me. Can you say you are not lucky? This county wants to win just like you!"

"Okay, I'm going home to sleep later. Please trouble the county master here to suppress them and not let them be lazy." Zhao Ping'an said.

Of course this is no problem.

Lu Shijie likes to do things like squatting and supervising, which is not very brain-using. At that time, he really stayed at Liu Meng's house for a few days.

Of course, it is not ruled out that he likes his aunt...

"Bastard, you are distracted and burned for half an extra breath!"

Unexpectedly, Professor Zhao was not here, but the students were even more miserable because there was a more nitpicious Lu Shijie guarding him.

"Damn official!"

"Is this guy a mentally retarded?"

"We are graduate students, and the process is still under development, so what he calls breathing, what is the anchor point?"

"By his brain capacity."

While recording the data, the students also used low-key discussions on Lu Shijie as a pastime for overtime work.

After all, students are students. They accept new things quickly, but they are easily distracted.

At some point, Lu Shijie went over and opened the box to check it out.

Because the room is a special greenhouse design, the impact of unpacking in a short time is limited.

This is the lifeblood of Jinling County. Lu Shijie molded the eggs one by one and found that the temperature was not too even.

"It's time to turn the ball over, why are you still standing there? If you cheat your little chicken in this county, you will never be able to study and career."

As a result, the students were really scared by the fainted official and rushed over to check.

Zhou Qing, who usually likes to find fault with sophistry, reached out and touched the egg and immediately changed his expression: "Hurry, artificial eggs, you can't wait."

There were three people next to him who cooperated with Zhou Qing and turned the balls according to Zhao Ping'an's instructions.

The other two students used their pens to quickly record the situation and recorded the handling methods of Zhou Qing and others.

After all, the equipment is very poor, and the reason why Zhao Ping'an asked them to turn over every time was: the temperature difference.

That is, the temperatures in various parts of the box are limited to uneven thermal conductivity and unevenness, which can easily form two or three sides of the egg, resulting in unqualified temperature differences.

Today's Song Dynasty can only have such equipment, so there is only the experience of using people and the multiple manual feeding of eggs to make up for the shortcomings of equipment.

In fact, it’s the same principle as cooking. Turn the hot ones up and the cold ones down to get heat.

As for how often they will turn it over, Zhao Ping'an doesn't know, so he can only let them try and make mistakes.

This is R&D. With the framework of Supervisor Zhao Da, the process is nothing more than the process of burning funds, statistics, and screening.

"Oh... these chicks are probably still in the womb."

After Zhou Qing checked the two incubators one by one, yin and yang eggs had already appeared on a large area, that is, one side was cold and the other was hot.

The originally joyful scene suddenly became silent.

"Come and record all the details quickly. When Zhao Ping'an comes tomorrow morning, he must let him see all the reports."

After Lu Shijie said that, he turned around and went out without even looking.

The students looked at each other for a while, and Zhou Qing said in confusion: "Is it because I was illusion that the last two sentences of this stupid official seemed to be... a little sad and choked?"

"No, this is not his egg!"
