Otaku Engineer in Great Tang Dynasty

　　 Li Mansion, West Yard.

　　In a makeshift simple workshop, the iron eggs are burning, and Li Zexuan is pouring white wine into the distilling pot and paying attention to the temperature in the pot.

　　 "Master, can you get stronger wine by heating this wine?"

　　 Tie Dan asked curiously.

　　 Li Zexuan sees that there is just time now, so he popularizes scientific knowledge for his cheap apprentice.

　　 "Just heating, of course, you can't get stronger wine, iron eggs, have you ever boiled water before?"

　　 "Well, of course it was burned."

　　 "Then have you found that after boiling the water, if it continues to boil, the water in the pot will become less and less?"

　　 "Well, Master, that's true."

Li Zexuan nodded and continued: "In fact, the reason why the wine we drink now is not strong is because there is too much water in it and too little alcohol. Oh, the intoxicating things in the wine are called alcohol. Master now wants What you do is to steam out the water in the wine to make the wine more concentrated, do you understand?"

　　 Tiedan nodded thoughtfully, and then wondered again: "Then Master, would you steam out the alcohol?"

　　 Li Zexuan exclaimed: "Tiedan, you have a good question. This is the most important part of distilled wine. In fact, compared to water, alcohol is easier to volatilize at lower temperatures.

　　 Uh, in other words, if they are steamed together, the alcohol will be steamed out first, and then we will add a tube flushed with cold water at the back, and the alcohol will become liquid when it is cold, do you understand? "

　　 The boiling point of alcohol is about 75 degrees. The temperature must fall below 75 degrees to liquefy. The evaporation rate is very fast at about fifty degrees, so at least the condensed alcohol should be cooled to below fifty degrees in the condenser tube. Generally, it will be cooled to about 30 degrees. Flow out. Of course, there are also lower cooling temperatures.

　　 Tiedan shook her head in confusion, and said, "Master, you understand what you said earlier, but later you said that the volatilized alcohol went into the tube and turned into liquid. This iron egg didn't quite understand it."

　　 Li Zexuan patted his forehead, but he could only explain to Tiedan the knowledge of junior high school physics that the solution vaporized when heated and the steam liquefied when cold, and Tiedan understood.

　　 "Okay, don't be distracted, you have a lot to learn in the future, now concentrate on burning the fire, pay attention to the heat."

　　 "Yes, Master!"

　　............

　　 Two quarters of an hour later, the thin tube of the condenser finally began to slowly flow out the concentrated liquor, and suddenly a strong aroma of wine filled the whole room.

　　 "Wow, it smells so good, Master, this is much more fragrant than my father usually drinks."

　　 Tie Dan vigorously sniffed his nose and said excitedly.

　　 Li Zexuan smiled slightly and couldn't comment.

　　 "Xiao Xuan, what kind of wine is this fragrant?"

Cheng Chumo outside the room, smelling the strong aroma of wine, he couldn't bear it, and immediately rushed in. This guy didn't know how to write the word polite, and he was about to come up and take the condenser while he was talking. Jars for wine.

　　Li Zexuan quickly stopped:

　　 "Stop, this new head wine is poisonous, you can't drink it!"

This product is really terrible. Although the freshly distilled top wine has a high alcohol concentration and smells very good, it contains a lot of low-boiling substances such as aldehydes, esters and ketones. If you drink these things, you will become blind. If it is heavy, it will die.

　　 Cheng Chu did not believe, "How can there be poison in the wine, don't lie to me, don't you kid, give me a taste, don't be so stingy!"

　　 Li Zexuan didn't bother to take care of this rambling, he saw that the top wine flowing out was more than two catties, so he changed the top of an empty wine jar, lifted the jar containing the top wine, and prepared to dump it.

　　 Cheng Chu silently saw his intentions and jumped anxiously behind him. If he couldn't beat Li Zexuan, he would definitely grab it.

　　 Li Zexuan poured the first wine into the yard, Cheng Chu stood silently and reluctantly stood there, sniffing the scent of wine remaining in the air, and muttered with regret: "Prodigal, prodigal!"

　　 Li Zexuan ignored him, turned around and returned to the house.

　　 An hour later, Li Zexuan brought out a jar of high-concentration wine, put it on the table next to Han Yuxi, looked at Han Yuxi and asked, "Yuxi, how is it, have you figured out the ratio of the ingredients?"

　　 Han Yuxi nodded, pushed a glass of red wine, and said, "Master, after I tried it many times, I found that this paired wine is easier to drink. You can try it!"

　　 Li Zexuan looked at the wine and hesitated, Han Yuxi smiled and said, "Master, don't worry, this wine is not intoxicating."

Li Zexuan just picked up the wine glass and took a sip. The entrance has the sweet and sour of shanguo. After a careful tasting, there is a hint of wine, mellow and sweet. Li Zexuan nodded with satisfaction. Han Yuxi is indeed a genius in making wine. After giving her a list of ingredients, she actually figured out the ratio of various ingredients by herself, which is really amazing.

　　 "Well, it's not bad, Yuxi, you are really amazing, just adjust it according to this ratio!"

　　 Han Yuxi heard Li Zexuan's praise, and immediately felt that her hard work was worth it, and she quickly agreed in a low voice, and then continued to mix the drinks.

　　 At this time, Cheng Chu came in silently and glanced at Li Zexuan with a pity, then he suddenly caught a glimpse of the cocktail prepared by Han Yuxi, and he immediately became energetic, he shouted:

　　 "Miss Han, is this the new wine you made? Let me, the master wine taster, help you taste it!"

　　 Han Yuxi couldn’t help but smile, Li Zexuan couldn’t help this cheeky~www.ltnovel.com~ Cheng Chumo poured a cocktail on his own, and then put it in his hand and exclaimed:

　　 "Well, it's not bad just to look at it, girl Han, Xiao Xuan is really lucky to be able to find you."

　　 This is a bit ambiguous, Han Yuxi's face blushed, Li Zexuan glared at him, and said in a bad mood: "Quickly drink, the wine can't stop your mouth!"

　　 Cheng Chumo laughed, picked up the wine, took a sip, smashed his mouth, then drank it again, and saw Cheng Chu silently sighed:

　　 "Miss Han, the taste of your wine is very novel. I have never drank such a wine before. Well, it tastes very good anyway. But it's a bit boring, not as good as the wine that Xiaoxuan poured out just now."

　　Han Yuxi smiled and said, "Master Cheng, this wine can also be served with strong, wait a moment."

　　 Li Zexuan saw that Han Yuxi was starting to drink again, so he pulled Cheng Chu out silently and said, "Ugly cow, come and help me move something!"

　　 "Uh, you won't ask the servants in your house to help you?"

　　 "Eat people's mouth is soft, take a short hand, have you ever heard of it, come with me if you want to drink good wine."

　　 Cheng Chumo could only follow in surprise, dare to make Lu Guogong's son the servant, Li Zexuan is no one.

　　 Li Zexuan asked Cheng Chumo to come here to help him carry a bag of saltpeter. Although this thing is not heavy, there is no need to use this free labor, lest the goods are spared there again.

　　 Last night, Li Zexuan asked his father to help him buy a few saltpeter mines, and he didn't know what happened to him.

　　 Li Zexuan just wanted to make some ice cubes, a strong cocktail. If you don’t add ice cubes, it will be too stomach-burning to drink. If you have ice cubes, it will be more refreshing to drink.
