Alcohol lamps, as the name suggests, are lamps that use alcohol as fuel.

Come to think of it, I first saw this kind of lamp when I was in junior high school. I remember very clearly that I saw this strange lamp in a chemistry experiment class.

Li Mengxi still remembers the precautions for using alcohol lamps. The important point is that the flame temperature of the alcohol lamp and the burning efficiency of alcohol are too high. It burns much more violently than ordinary oil lamps and candle flames. Therefore, it cannot be blown out.

Extinguish the alcohol lamp, because the air blown out also contains oxygen, which will promote combustion.

The correct method is to use a lampshade to cover the alcohol lamp.

Because he was looking for lamps for Tian Bu, Li Mengxi suddenly thought that since alcohol was being made, he could also make alcohol lamps.

How difficult can it be to make an alcohol lamp? One is alcohol and the other is lamp twisting. The lamp twisting may require cotton thread. Other than that, what is the difficulty?

Li Mengxi couldn't wait to go back to the city to see if the wine steamer was ready.

When I returned to the city, I found the craftsmen who were burning a kiln. The craftsmen built a small kiln to make pottery temporarily.

Another technology that made Li Mengxi very curious was how pottery was fired.

But because I arrived late, I didn't see the key kiln building process, so I didn't see the complete process.

The pottery still hadn't been fired yet, so Li Mengxi couldn't help it, so he had to offer a few words of comfort and kind words, and then went back and sat on the threshold of Zhang Fei's house, waiting boredly.

Although Li Mengxi did not urge him, the potter and the blacksmith were very discerning. When people came over to see it, they made it clear that they were in a hurry to use it, so the potter and the blacksmith filled the kiln with firewood more diligently.

In the afternoon, when the sun was about to set, Li Mengxi heard the sound of gongs and noises outside the alley. A vicious voice was beating the gongs while cursing. He listened attentively, and it seemed that he was shouting about the food requisition and the suppression of the Yellow Turbans.

, whoever dares to refuse to surrender will be put in jail.

Li Mengxi listened for a while and smiled.

The county magistrate is indeed as Liu Xuande expected. How can he have the courage to recruit the powerful and powerful people, but he will eventually fall on the people. Everything is as expected.

Ah.

After a while, two craftsmen who had been busy for a long time came to visit and said that the things were ready.

Li Mengxi followed the craftsmen to see the pottery that had just been fired. It was pink in color. When water was poured on it to cool it down, it smoked. The moment the water touched the pottery, it turned into steam.

After another moment, when the pottery cooled down, Li Mengxi reached out to touch it, but it was already cold.

Li Mengxi found that the wine-holding part was a large pottery jar. It looked like a kimchi jar. That is to say, the rim of the jar was relatively large, and some water could be poured into it. Then a bowl was placed on top of the water.

It can be sealed with water to prevent alcohol vapor from escaping.

The difference is that the kimchi jar is sealed with a bowl or a bowl-shaped lid, while the wine steamer has a flat lid.

In fact, it might be better to use a bowl.

Then, there is a long guide tube that is curved like a teapot, and the guide tube and the condenser are connected together.

As the most important part of the entire wine distiller, the condensation structure. Li Mengxi looked at the small clay pot with thin copper sheets inserted all over it. The more he looked at it, the more it looked like a seismograph, or perhaps Taishang Laojun's alchemy furnace.

If the copper leaves used for heat dissipation on the tank are replaced by some things like gourd leaves, dragons and phoenixes, it will look more like it.

Li Mengxi could already predict what the distillation process would be like. Judging from the volume of the wine container, it was as big as a bucket. It was estimated that seven or eight jars of wine could be poured. Then, the bottom of the wine container was heated. After the water and wine were heated, the boiling point was low.

The alcohol evaporates first. Along the pipe, the alcohol flows into the condenser. The hot alcohol vapor hits the cold copper sheet inside the condenser and immediately liquefies into alcohol liquid and drips. Then, at the bottom of the condenser, the craftsmen add

It is made into a structure that cannot store wine. If there is a drop of wine, it will flow out directly. In this way, the wine head can be removed very cleanly.

Then, the alcohol vapor continues to flow into the condenser and is continuously liquefied. At this time, the copper sheet absorbs heat and will slowly become hot.

The copper sheet inside generates heat, and the heat is conducted to the copper sheet outside. This is why craftsmen smash the copper sheet into a shape like a bamboo dragonfly blade, thin in the middle and wide at both ends. This is because the contact area with the air is large and heat dissipation is possible.

Large area, faster heat dissipation.

What to do when the condenser heats up? Take cold water and pour it directly to cool it down.

This is the original condensation structure designed by Li Mengxi. Its inspiration came directly from the military camp that day, when copper arrows and other objects were used to condense. The inspiration came from that time.

Looking closer, Li Mengxi was surprised to find that the copper sheet of the condenser looked purple.

Copper seems to be yellow.

Li Mengxi was confused.

The whole set of utensils is completely sufficient, "very good!" Li Mengxi praised, this can be regarded as an evaluation of the busy half-day work of the craftsmen.

Then, Li Mengxi said that the work was done and asked the craftsmen to go back first.

The craftsmen said goodbye, saying that if there was any work, they would come back to us.

Li Mengxi smiled and said, "Okay! I'll help you two next time." He said goodbye to the two craftsmen with his hands.

After the two craftsmen finished their work, they were in a happy mood. The employer did not press or make things difficult for them, nor deduct wages from their work. They also spoke nicely, which made the two craftsmen feel very good.

The wine steamer was ready, and Li Mengxi couldn't wait to start the business of steaming wine.

He went to see Zhang Fei's servant, "Where is the wine your master prepared for me?" Li Mengxi asked.

The servants brought the wine over one by one.

I thought there would be four or five jars of wine. However, when people came in an endless stream, one jar after another, without stopping, and when they brought the jars over and stacked them up in rows, Li Mengxi felt that things were not as expected.

Simple.

Damn it, Zhang Fei is so careless, he won't get all the wine in the house, let me distill it for him, Li Mengxi's eyes widened, extremely surprised.

As Li Mengxi expected, in the end, there were two large piles of wine jars, one pile six or seven stories high.

A mathematical problem, a very classic mathematical problem, that is, there are a bunch of wine jars. There are eleven wine jars on the bottom layer, ten on the next layer, and nine on the next layer.

By analogy, there are five wine jars on the top floor. How many wine jars are there in total?

To find the sum of an arithmetic sequence, right? Li Mengxi counted, rolled his eyes, tilted his head and thought, and calculated, fifty-six altars.

If the two piles are the same, there are a total of 112 jars of wine. If they are different, don't worry, it's a waste of time to count them.

The difficulty in placing the still is that it is inconvenient to heat it when placed on the ground. It is also inconvenient to hang it with a rope and have to find a wooden shelf.

What to do? Li Mengxi thought of watching the craftsmen use bricks to back up the planks when building the stove.

Very good, the method I just saw came into use immediately.
Chapter completed!
