The principle of the fractionator is the process of cooling and separating water and alcohol into relatively pure alcohol due to the different boiling points of two liquids. Pen, fun, pavilion www. biquge。 info

The two kinds of steam enter the fractionator at the same time to be condensed, and the subsequent steam will reheat the descending condensed liquid to make it vaporize again, the boiling point of alcohol is lower than the boiling point of water, and it is easier to vaporize when heated again, and the boiling point of water is high, and it will continue to fall, so as to obtain relatively higher purity alcohol. This is a complex process of physical change, but the principle is very simple, in fact, it is a multiple distillation process.

After Wang Mai explained, Song Laosan was dumbfounded.

"Don't understand?"

Song Laosan shook his head like a rattle.

"Then I'll say it again, because ......"

"No need to ......" Song Laosan grabbed his hand, "No need to explain, my head is almost big." As long as this thing is easy to use, I'm a rough person, and I don't understand if you say too much. ”

Wang Mai opened his mouth. Forget it, it can be a bit difficult to get a mud-legged big-headed soldier to understand this physical process.

"Just tell me how strong the wine is?" Song Laosan begged for mercy.

"I wasn't sure before it came out of the pot, but it was very strong anyway." Wang Mai said.

"Stronger than the best sake in Linluolou in West City?"

Wang Mai tilted his head and snorted disdainfully. Linluolou is named because it was built next to Luoshui, last time in order to celebrate Wang Mai's "release from prison", but also to celebrate the victory of "hunger marketing", Song Laosan invited Wang Mai to rub it alone.

When Dr. Jiu introduced, he said that the sake in Linluolou was the first in Luoyang in terms of taste and strength, and the two of them asked for three liters. As soon as he entered Wang Mai, he smiled, this wine is indeed much stronger than ordinary turbid wine, but at most about 20 degrees, in later generations, even the threshold of medium wine can not be stepped into. Three hundred wen a liter, it is still in short supply, and after a meal, it cost more than two yuan, Wang Mai felt that it was not worth it.

Song Laosan's eyes lit up: "Then tell me what kind of martyr's law it is?" ”

"Let's put it this way, if the wine is medium, the average person will faint after drinking half a catty." Wang Mai thought for a while and said.

"What?" Song Laosan looked at Wang Mai in disbelief.

Wang Mai nodded: "With the amount of alcohol you drink, at most one pound will be poured." "Song Laosan is relatively able to drink, he plays well, and he can fight with Wang Mai to lose both.

"Wait for me!" Song Laosan couldn't help but say, turned his head and went into the house, and after a while, he took off the armor on his body.

"You're not worth it?"

"Just find someone to replace me." Song Laosan said nonchalantly. As the saying goes, money can be channeled, and since he opened a store to do business, he has asked for leave for three days and two ends, so he has already taken care of the upper and lower levels.

It would be a hell if this kind of army's combat effectiveness could beat Li Tang, Wang Mai sighed.

After Song Laosan arranged everything in the barracks, the two of them found a blacksmith's house that had built a coal stove before.

"This ......," the blacksmith looked at the blueprints by the still bright light outside, and looked embarrassed.

"If there is any difficulty, just say that money is not a problem." Song Laosan asked anxiously on the side.

"It can be done, but this iron bucket is so thin, I'm afraid it won't be strong even after it's done." The blacksmith shook his head and pointed to the blueprint, "And you see this long pipe, it's so long and thin, it's bumpy, and it can easily break." ”

Wang Mai looked at the cooling pipe that the blacksmith was referring to in the design drawing, and his brows furrowed. The ancient smelting technology was too backward, and this person was just a folk blacksmith with good craftsmanship, which was indeed a bit difficult for him. In ancient times, there was no stainless steel, and even if this fractionator was made, it would be quickly corroded by water vapor.

"Then you can see if you can make it out of copper?" Wang Mai said helplessly. Last night, he only thought about the use of this thing, but he didn't expect to be limited by materials now.

Materials science is an indispensable discipline in modern industry, and many things, even if they can be made theoretically, are often limited by materials. Even if a prototype is made, it is still a difficult question whether it can be mass-produced.

"The government has long stipulated that people are not allowed to cast bronze privately, and I am just a blacksmith, which ......" The blacksmith looked embarrassed.

After hearing this, Song Laosan could see that this guy still wanted to process money. After the last big sale of coal stoves, the blacksmiths in Luoyang City have made a fortune one by one, and now they have tasted the sweetness.

Thinking of this, he sneered: "You are a shabby, Lao Tzu is custom-made things for you, I look up to you, the coal stove made money last time, and I can't look down on Lao Tzu's business, right?" You inquire throughout Luoyang City, Lao Tzu is a dignified general of the forbidden army, although the tiger has fallen in Pingyang now, it is not difficult to make you a stinky blacksmith. ”

"The third master has something to say," the blacksmith hurriedly said to him, "I didn't mean that." ”

Wang Mai also grabbed Song Laosan: "Old Song, you are also a dignified general of the forbidden army, why bother to have general knowledge with him." ”

Song Laosan smiled coldly: "Brother Wheat, you don't know, last time it was this guy who leaked the coal stove drawings you worked so hard to draw." He glared at the blacksmith, "I didn't embarrass you last time, and Hugh is going to find these people to prevaricate." What is forbidden by the government? Now there are not 10,000 but 8,000 people in Luoyang who privately cast copper, and they have not seen the government pursue it. You are lost in money, and you don't know whether you are dead or alive. Turn around and smash your blacksmith stall, see if you are still sloppy with the two of us? ”

When the blacksmith heard this, he hurriedly said to him: "Third master, I don't want to give them the drawings either." You know those merchants in the South City and the West City, they come to the house every day to block the door, if you don't give them to them, my family will not be able to live a life. ”

Looking at the blacksmith kneeling on the ground, Wang Mai was a little unbearable: "Old Song, forget it." Even if he doesn't give these people a blueprint, they will buy our coal stove and go back, and it won't take long to study it thoroughly. ”

Song Laosan nodded when he heard this, and looked at the blacksmith: "My brother is a scholar, and he is kind-hearted and doesn't care about you, so I will spare you for this matter." You have a good word, can you do it? The money will not be short of yours. ”

"Yes, yes." The blacksmith stood up, and the chick pecked at the rice.

"If it's done this time, if Lao Tzu finds out that you gave the drawings to others again......," Song Laosan smiled, "Don't blame me." "Don't look at Song Laosan's usual conversation and laughter with Wang Mai, the size is also a soldier's head, this stare is also quite deterrent.

"You can rest assured. I won't dare anymore......" the blacksmith hurriedly patted his chest and assured.

When the two of them left the blacksmith's house, Wang Mai looked at Song Laosan with a smile: "I didn't expect that you kid would scare people and be a bit of a general." ”

"Alas......" Song Laosan sighed, "I was also born in poverty, and I died early when I beat my little father." Fortunately, being in the military, he can mix a mouthful of food and not starve to death, and this poor man also understands his thoughts. It's not that he's bullied him as a blacksmith, it's just that in these days, people are good and are bullied. Brother Wheat, you are a scholar, you have never suffered much, and you have never seen people starving to death. Back then, I was still a big soldier, just in time for the conquest of Liaodong, so I was promoted by cutting off the heads of a few Goguryeo people. The million-strong army, seeing that it was about to level Liaodong City, gave an order from the Emperor of Daye, and retreated like a tide, and he didn't even have time to bring food. He was talking about Emperor Yang of Sui's second expedition to Goguryeo.

In the ninth year of the Great Cause, Emperor Yang Guang of the Sui Dynasty launched the second war against Goguryeo after the failure of the first expedition to Goguryeo. The army besieged Liaodong City for more than 20 days, and in order to climb the city wall, all kinds of military equipment for attacking the city were like a high mountain. Emperor Yang of the Sui Dynasty also brought more than one million sacks with the army, and planned to use these more than one million sacks to build a "Yuliang Avenue" that leads directly to the top of the city wall under the city of Liaodong on the day of the general attack. But just before the general offensive was launched, news of Yang Xuangan's rebellion in China was received. Emperor Yang of Sui, who was afraid that the back road would be cut off, ordered a retreat, abandoned all military resources, and fled the whole army.

"On the way to escape, because the rebels discarded the grain, they robbed the counties along the road, you didn't see it, it was called a miserable." Song Laosan said sadly, "The army has robbed all the food of the people, and there is still not enough to eat, and there are dead corpses everywhere along the way, and some people even ......."

Needless to say, Wang Mai also knew that the tragedy of cannibalism in history textbooks happened next to Song Laosan.

"For a bite to eat, man is not a man, he is fiercer than a wild beast, he is very hungry, and his eyes are green when he looks at people, like a wolf. I slept with a knife on my pillow at night, afraid of being killed, and cooked and eaten. Song Laosan breathed a sigh of relief, "Fortunately, I have a big life, and I can always find some grass roots and bark when I am hungry, so I survived." ”

Song Laosan shook his head: "What are you talking to you about?" Alas...... Just thinking about those days makes my scalp tingle. Later, I finally understood that people live this life just to be able to eat. ”

Wang Mai patted Lao Song on the shoulder and comforted him: "Don't worry, you won't starve in this life." ”

"That's nature. Fortunately, I met you, Brother Wheat, and I don't dislike that my brother is a big boss, and this bitter day has only recently become sweet. Song Laosan had a smile on his face, "Anyway, this method of brewing wine can make us earn a lot, right?" After two years, it is better to wait for the girl to get married, buy more dowry, and find a good family. You also marry a few more ladies and give birth to a few more big fat boys to make the old man in the family happy. ”

"Alas......" mentioned the topic of marrying, Wang Mai couldn't help but think of the Rou Niang who set up a stall.

"What are you sighing for?"

"I'll tell you the truth, I really have a heart for a woman, but it's a pity that ......" Wang Mai told him about Rou Niang.

"You ......" Song Laosan shook his head, "I'm also an official, who can't do it, and I think about a married woman." A woman's family, when she comes out to show her face, she is definitely not a serious person. You want to marry and want to get lost, turn around and ask your sister-in-law to find a good girl quickly. ”

"Don't talk about it......," Wang Mai smiled bitterly, "Let's talk about this winemaking." ”

"Except for that...... What else do you need for a fractionator? Song Laosan asked.

"A cauldron is needed...... Not only the grain, but also koji, and good charcoal. Wang Mai thought for a while and said.
