Chapter 427 The Method of Filtering Bitter Salt

……………………………………

Seeing Li Erwa hurriedly running closer, Liu Hanshao asked, "Tell me, why is the salt we usually eat different from this?" ”

Hearing the master shouting at himself in such a hurry, he thought something big had happened, so he asked this.

Li Erwa said very generously: "Master, what we eat is tribute salt, how can there be mud and sand in it?" Then you have to turn this coarse salt into water, and after clarifying, only the top clear part is taken, and then boiled into salt and ground into small grains. ”

Burst...... Liu Hanshao suddenly felt that he was so stupid, so stupid...... It's so naïve!

Since he ascended the throne, Liu Hanshao has not asked others to pay tribute to himself, and the food and clothing of the Yong'an Palace, which is the family, are all purchased by Yun Eighteen Cavalry, and it is certain that things are bought better, but the difference is that other people's families buy a piece of eight, and our family buys three pieces of six, who will let our wife make money.

Therefore, when he was a "dead monkey", the salt that Liu Han rarely saw was small particles, and the salt he saw after the emperor was still small particles, so he thought that the salt in the world was like this, and the difference between "fine salt" and "coarse salt" was the difference between smaller particles and larger particles.

But salt is the thing...... Eat, Eat, Slow!

In the past and later lives, it was rumored that the little devil was leaking, and she also followed the trend to buy a lot of salt, and she couldn't eat it all later, let alone the palace inventory?

You're digging a pit together, waiting to see your brother embarrassed, right?

It seems that no one else is to blame for this.

Fortunately, fine salt is not minced meat, and it should be normal for the emperor to not know the difference, right? And now no one dares to laugh at Liu Hanshao, or if he wants to laugh, he has to hold it all in his stomach.

Finally, in front of the romantic "Rose Lake", Liu Hanshao let go of Yun Liuniu's little hand and walked along the "ridge" towards the salt field. Seeing this, the others wanted to follow up, but the ridge was narrow and couldn't accommodate so many people, Yun Liuniu stopped others, but she ran towards Liu Hanshao quickly, and then Xu Chu asked Dian Wei to follow.

There were a few ordinary salt workers in the salt fields who were drying salt, of course, they were all carefully selected "Aihan people", and when they saw Liu Hanshao actually walking towards his group, they were all at a loss, because there was no such project at all during the "rehearsal" in advance.

Then, an elderly salt worker seemed to be the first to react, and he knelt on the ground in the salt field, and said tremblingly: "Little old man knocks on my emperor!" ”

Seeing this, the rest of the salt workers followed suit. Liu Hanshao walked a few steps, jumped into the salt pan, hugged the old salt worker and said, "Old man, get up, get up!" Hurry up, everybody. ”

It was not appropriate to stand in the salt field and speak, Liu Hanshao helped the old salt worker to walk up the ridge, and did not forget to turn back and say to the other salt workers: "Everyone hurry up and take a rest." ”

This move not only flattered a few salt workers, but also the officials in Hedong who were far away on the bank were also stunned, especially the moment Liu Hanshao jumped into the salt field, thinking that His Majesty the Emperor had an accident. However, what made everyone feel even more incredible was that after Liu Hanshao went up to the ridge, he sat down casually, took off his soaked shoes, and talked with the salt workers, but they were a little far away, and everyone didn't know what His Majesty and an old salt worker could say.

"What's the old man's surname?"

"Ouch...... In front of my emperor, I can't do it, I can't do it! small

Lao Er's surname is Niu, you just call Lao Niu. ”

"Oh...... How many years has Lao Niu been in this business? ”

"Back to my emperor, the little old man has followed my family to learn to dry salt since he was a child, and when he was fourteen years old, the head of the family gave me a salary, and now it has been more than 30 years."

Fourteen plus thirty.

Xuezhu calculated a little, and then said, "Well, then you're not old." ”

Maybe because he said a few words, Lao Niu was not so restrained, and waved his hand at Liu Hanshao again and again and said: "Old, old, my legs and feet are getting worse and worse." ”

Following Lao Niu's words, he looked at his legs and feet, but he didn't expect it to make Liu Hanshao's heart tense for a while. Salt workers work barefoot in the water, and even if they soak in fresh water for a long time, their skin will wrinkle, let alone salt water. When you soak it, it will be wrinkled, and when you don't soak it, the skin will be dry, peeling, or even cracked. If there is a crack in the foot and then soaked in salt water, the sourness is not something that ordinary people can imagine, and it is not an exaggeration to say that it is a punishment. But this is the case with the old cow's feet, no matter how good they are cracked, no matter how good they are, they are cracked again, and the scars are layered on top of each other, densely packed, like the bark of an old tree. If it weren't for the toe propping scene, I really wouldn't have seen that it was a foot. TVmobile/

Then, through a conversation with Lao Niu, Liu Hanshao finally figured out that although there are now salt pans piece by piece, which belongs to the "reclamation and watering method", the brine has not been filtered, let alone diluted with fresh water, so it is not difficult to understand why there are so many impurities in the salt blocks, and they are bitter.

After that, Liu Hanshao did not go to the place where Wang Yi prepared for himself, but asked Xu Chu and them to set up a camp next to the salt pond, planning to think carefully about how to solve the problem of salt being bitter.

Teacher, what did you say back then?

Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon. Sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chloride...... Donkey...... Oh, teacher, is it too late to make up the lesson? Brother gives you gold cakes!

…………

In the days that followed, Liu Hanshao embarked on a bold experiment.

First of all, the lake water has to be filtered before it is poured into the salt pans, and a large net of bamboo chips is sandwiched between straw rows to intercept the materials in the lake water. When the lake water evaporates and the salt in the water rises to brine, it is filtered through bamboo slices and layers of mats, and then flows through the ditch to another salt pan, where fresh water is added and waiting for evaporation and crystallization.

"Oh, this muddy ditch must not work, otherwise we will filter so many times in front of us, and we will all be blind? We have cement, build it into a cement trough. We are now using two salt pans together, the former one is called "brine pool", the latter one is called "crystallization pool", there should be a "purification pool" in the middle of them, of course, it doesn't need to be too big, let's just put a few layers of straw rows and mats here, so that the brine can seep through here. Yes, this purification tank should also be built with cement and connected to the sink. ”

The experimental team with Liu Hanshao as the main and Li Erwa as the auxiliary worked for several days, and finally was about to see the results of the experiment, but unfortunately it is now close to the Mid-Autumn Festival, and there is still some heat around noon, which is not a good season for drying salt. And Liu Hanshao couldn't delay here any longer, there were still many places waiting for him to go, so he told Li Erwa to stay for the time being and wait for the results of the experiment.

Li Erwa asked with some complaints: "Master, the brine that was finally dried, why do you have to add it to it if you don't wait for the salt to come out...... Add fresh water? ”

"You don't understand, do you?"

Liu Hanshao was afraid that he would not be able to say it well, so he would deny Li Erwa first,

Then he continued: "There is not only salt in this brine, but also many other impurities, such as magnesium sulfate and sodium sulfate, and the salt tastes bitter because of them. The temperature of fresh water is low and the temperature of brine is high, so that the original temperature of the brine can be adjusted, and these impurities can be decomposed to form a nitrate plate. When you look back, you have to pay attention to sink down to the bottom first, the bitter taste is the nitrate plate, and the salty top is the salt, you don't scrape it all back. ”

"Oh, just the top, not the bottom."

Then Li Erwa asked again: "That master, the nitrate ...... down there Nitrate, even if you don't want it, do you have to scrape it out and throw it away? Otherwise, the next time you dry salt, won't it be more bitter? ”

Liu Hanshao hurriedly said, "Don't." Just leave it at the bottom of the pool! ”

"Why?"

"Because in the future, whether you can easily dry the salt that is not bitter is all on this nitrate!"

Li Erwa asked with a sad face: "Didn't the master say that this nitrate plate is an impurity?" It's bitter, why do you have to rely on it to make salt that isn't bitter? ”

This one...... With Liu Hanshao's knowledge and Li Erwa's comprehension ability, I'm afraid it's hard to say clearly.

"Erwa, have you ever paid attention to the oil flowers floating in the vegetable soup when you cook, what will happen if they touch each other?"

"If you bump together, you can bump together, what else can you do?"

Li Erwa thought about it, and said again uncertainly: "Will it become a large oil flower?" ”

"Yes, that's it!"

Liu Hanshao patted Li Erwa's shoulder appreciatively, and said solemnly: "The nitrate plate is like an oil flower, it will form a piece when it touches it." Therefore, the more times you dry the salt in the future, the nitrate board will become bigger and bigger, and slowly smooth the salt pan, as if a layer of floor tiles has been laid. Drying salt on a nitrate board can absorb the impurities in the brine, and secondly, it can also isolate the sediment, so the salt is clean and not bitter. ”

Li Erwa nodded seriously as if she understood, and then said, "Master, then you have to walk slower on the road, and when I have dried the salt here, I will chase you immediately." ”

You are such a big fat man, and you still have a seven-star treasure knife pinned to your waist, can you not be so reluctant to talk to your brother? Brother is not your family!

Liu Hanshao really wanted to kick Li Erwa, but he smiled and said kindly: "Go, make something delicious for the master, let's add a meal." ”

As soon as she heard this, Yun Liuniu, who had been sitting next to her for a long time, immediately said, "Second baby, make one for my sister too." ”

"And me."

"Do more."

"Count me in."

This up-and-down voice finally made the "abandoned" Li Erwa regain her confidence, and she responded again and again, happily jumping out of Liu Hanshao's big tent.

Looking at this fat back, who would have thought that it would be a talent closely protected by the military government? The big cook, no matter how big he is, he is still a fat cook!

…………

Whether it is possible to make salt that is not bitter, in fact, Liu Hanshao is not worried, even if it doesn't work, at most it is to eat less bitter salt, anyway, he has eaten it for so many years before. But even if it is bitter salt, can the poor people afford it?

Before, Liu Hanshao's biggest wish was to let the people be fed and clothed, this is really not "thinking about the world", but thinking that everyone will not make trouble when they are full, and his position as emperor can be a little more stable.

However, even if you are full, what is the meaning of a tasteless meal?
