Jiang De looked at the few people who were ignorant, and sighed, what he just said, if he was to the junior high school students of later generations, I believe they would all understand it as soon as they heard it, but to these villagers, these villagers would only feel that the second monk was confused.

Jiang De said more simply: "Everyone, recall, is there a phenomenon that boiling water at home will produce white water vapor? ”

"Yes, yes, yes, but so." As soon as he said this, some villagers immediately reacted and said.

Jiang De saw that he understood this, so he continued: "So does the white water vapor turn into water again when it touches something cold?" Think about it, will there be water condensed from the lid of the pot where the water is usually boiled? ”

"Yes, yes, yes! Well, I used to wonder why this was happening, but I couldn't figure it out, so I stopped thinking about it. A young villager said.

"Haha, have you thought about it? I never thought about it. Another villager smiled and said, "What do you want to do with these useless things?" ”

Jiang De frowned, pointed to the person who said why he had thought about it before, and said, "What's your name?" This is not a useless thing, and it should be rewarded to think of such a thing. ”

The young villager touched his head and said, "My name is Wang Xiang." ”

Jiang De nodded to show that he remembered, and continued, "You remember, wine is more likely to become white vapor than water, so we only need to boil the wine, and then collect the white water vapor that evaporates from it to get pure wine, I call this kind of thing alcohol, which means the essence of wine, this instrument!" Jiang De patted the huge steel utensil and said, "It is something used for steaming wine, since this is to collect wine gas, then it needs to be sealed to prevent wine leakage, the gap in the wood is too large, and the iron is easy to rust, the material of this utensil is made through a special process, which is extremely precious, you should cherish it when you use it, understand?" ”

"Got it!" Several villagers responded.

Jiang De pointed to the next few vat of wine and said, "It's better to say this a hundred times than to do it again, Wang Xiang, you take two people to carry the wine over, you pay attention to here, this is the feeding port, next to the feeding port is the observation port, come, pour the wine from the feeding port, pay attention to turn on the switch first, that is, this handle." ”

Jiang De is like teaching children, little by little to guide the villagers to use this wine steamer, several villagers carefully carried the wine, with the yellow-white wine poured from the feeding port, the glass observation port next to it can be seen that the wine is slowly full, seeing this transparent observation port, all the villagers are stunned, in their memory, have never seen such a transparent and visible thing, only feel that this must be a peerless treasure.

In fact, it is not bad, such a long piece of glass, at this time, the price is probably really worthy of the title of this peerless treasure.

When the water level reached the red line, Jiang De shouted, "It's okay, you see, when you get to this red line, it means that it is full, the wine in it is about one stone, and now you can start steaming wine, this steamed wine has a long staying power of fire, so you must choose coal, that is, black stone, but burning black stone will produce poisonous gas, this poisonous gas will not poison you immediately, but it will make you slowly unable to breathe, so be sure to open the window." ”

Jiang De is really afraid that these villagers will be suffocated in the house because they don't know the power of carbon monoxide, not to mention this era, even in the future, there will be news that students or migrant workers will die in the house because of burning coal every winter.

In fact, coal burning was already very common in the Song Dynasty, so I also had a certain understanding of gas killing, although I don't know why this happened, but I also knew that as long as ventilation could keep peace.

The fire was lit, and it took a lot of time to boil a hundred kilograms of wine, so Jiang De hurried to explain the next operation to these villagers

"This wine will be burned for a period of time, I will continue to say later, you see, there is a pipe above this steaming barrel, and the thick pipe that he leads to is the condenser tube, and the last barrel is the secondary condenser pipe, in order to speed up the condensation, there is a water inlet here, you have to keep adding cold water, so that the temperature of the condenser tube is reduced, you can first add cold water and wait for the steamer water to boil." Jiang De pointed to the water inlet of the large bucket behind him and said.

Everyone hurriedly filled the water inlet with water, and there was also an observation hole in it to see the situation inside.

Jiang De has always believed that if you want to do a good job, you must first understand its principle, only know it, don't know why it is, at most it is just a skilled craftsman, it is impossible to become a real everyone.

And these villagers are all candidates for the owners of wineries that may be all over the country in the future, others can not understand, but they must understand.

Temperature, concentration, boiling point, one by one nouns slowly explained, time flies, and in the blink of an eye, the steaming barrel begins to boil.

Looking at the boiling steaming barrel, Jiang De said to the villagers, "Then let's talk about it first, you have to digest it well when you go back, I have to ask a question tomorrow, if anyone can't answer, don't blame Xiao Langjun, I turned my face and didn't recognize people!" ”

The eyes of several villagers were already a little glazed, and although what Jiang De said was something that they had seen every day, it was completely beyond their comprehension. It is difficult for some strong people to accept it at once, but Jiang De has no choice, he can't train those children now, and when those children grow up, he can only let these villagers learn how much first.

Compared with the learning theory, the villagers are obviously more interested in practice, everyone watched the wine boiling at the observation mouth, they were a little excited, only to see the steam slowly passed through the condenser tube, and then quickly turned into liquid under the cooling of cold water, Jiang De took the opportunity to instill the principle of liquid and gas change again, this time combined with reality, but it made the villagers understand much better.

"Quick! The head of the wine is coming out, go and get the jar of wine! Jiang De shouted, Wang Xiang was really the most clever among the people, and hurriedly brought a clean wine jar over, Jiang De put the wine jar at the wine outlet, and said, "Go and get a jar again, you remember, this steamed wine is divided into three kinds, respectively called the first wine, the middle wine, and the tail wine." This wine is the first wine to be steamed, and this wine contains methanol, aldehydes, fusel oils.... Anyway, it's some bad things in the wine, so it has to be packed separately, but this wine is not useless, this wine has a high degree and high purity, and it is best to use it to make disinfectant alcohol, and the head wine is about two percent of the previous one... How so? It is about two catties of head wine in a hundred catties of wine. ”

Looking at the transparent head wine flowing out of the water, a rushing aroma of wine also came out, smelling the aroma of the wine, everyone showed an intoxicated expression, this is a taste that no one has smelled, Wang Xiang looked at the wine like a sweet spring, and only felt that it was the most beautiful existence.
