Chapter 323 Manifesting God, Sun Xin Boils Refined Salt

After receiving Jie Bao’s complaint letter in Dengzhou, Sun Xin recalled that in his previous life, he seemed to have heard a friend from the salt industry company say: the Baumé degree of seawater in the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea is the difference in salt content. Not small, among which the East China Sea and the Yellow Sea are the lowest.

Therefore, drying salt in Haizhou must be done on a large scale to be profitable.

With the current size of Sunjiazhuang in Haizhou, it is obviously impossible to achieve such a level, but Sun Xin never planned to rely on large quantities of low-priced private salt to support the Niugang Village Supervisory Committee from the beginning.

Since there are few people here, it is natural to make high-end refined salt.

There is also pure sea salt in this era, and that is the unique skill of salt workers in Zhejiang-Wu Yan.

The production method of Wu salt is also very simple, which is to crystallize seawater once to make coarse salt, then dissolve the coarse salt in clean water again, and boil it until dry again, because the solubility of sodium chloride and its metal salts in sea salt is different at different temperatures , Skilled employees can judge according to the state of the brine when the amount of salt precipitation is the largest, and when most of the salt is precipitated, the remaining brine is poured out.

This goes on and on, every time it is dissolved and recrystallized, the proportion of sodium chloride in the obtained salt will be higher. After repeating this for more than ten times, the "pure white Shengxue" Wu salt can be produced.

This method of recrystallization, thinking about how much labor will be consumed, so the price of Wu Yan can be sold at three hundred yuan per catty or even higher. At this time, it is sold as a good gift or even a health care product.

For Sun Xin, it is too simple to precipitate the metal ions in the salt.

The purpose of adding sulfuric acid to the brine first is to make the calcium, silver, and barium ions in the brine form sulfates. These three sulfates are almost insoluble in water and will precipitate directly.

In order to ensure that there are no sulfate residues, Sun Xin asked the farmers to add some snail shells to the brine. The main component of the snail shells is calcium carbonate, and the calcium ions in it will react with sulfate radicals until the snail shells are no longer there. Bubbling means that the sulfate radicals in the water have been consumed.

Sun Xin left the brine to let the sediment fall to the bottom of the salt pond, then opened the passage leading to the next salt pond, and put a piece of bamboo at the bottom of the passage, the clear brine on the upper layer slowly flowed down and the sediment on the lower layer The brine was kept in the salt pond.

Sun Xin then added caustic soda to the brine entering the next salt pond.

The remaining calcium ions in the brine will react with caustic soda to form calcium hydroxide and precipitate.

Change to another salt pond, filter out the precipitate, and finally adjust the acid-base balance. The brine that is ready to dry directly makes the eyes of several salt workers shine.

The brine in the salt pond in front of them was clearer than the best brine they had ever seen.

In the past, this kind of brine had to be dissolved and dried at least seven or eight times before it could be produced, and the best staff had to be at the helm to scrape off the sea salt when it was the purest, but Sun Xin only took one afternoon Just made a pool full!
Sun Xin looked at the pool of brine, but he was not so happy. It was his first time to use chemical methods to make salt, and the purity of sulfuric acid and sodium chloride produced by Sunjiazhuang's small workshop was really not high, although several employees had already looked at each other. Surprised, but Sun Xin still has some doubts about the quality of the salt he made.

He directly asked the farmer to scoop out a pot of brine and boil it out to have a look. Several salt workers did not let their children do it. A few gray-haired old people carefully scooped out the brine and poured it into the iron prison basin. They thought the brine was too precious. , wasting a drop seems to be a great blasphemy.

Several old men personally guarded the fire and burned it for three hours, scraping off the salt in time. When the hot sea salt was scraped off, the eyes of the salt households, young and old, were all red.

"White!"

"How can it be so white?"

"So this is Wu Yan Shengxue!"

Although I haven't had time to taste it, the first thing I can tell is that the salt is really white, as white as snowflakes in the twelfth lunar month of winter, so clean that people can't bear to touch it.

An old salt worker even shed tears unconsciously. He has never seen such beautiful salt in his whole life as a salt farmer.

When Sun Xin and Xie Bao came to look at the iron prison basin, they saw an old salt farmer asking his grandson to fetch things from the work shed.Soon his grandson came running back with a bamboo tube in his hand.

The old salt household opened the bamboo tube and poured it out. Only then did Sun Xin realize that it was the salt they had brought from Dengzhou to make themselves.

Those white salts are the good salt left by the Yan family. They make a little on a small scale and are reluctant to sell it. But grab a handful of the good salt they made and a handful of freshly cooked Sun Xin. When Haiyan was compared, everyone was surprised to find that the white salt they had brought was thrown away in front of Sun Xin's salt.

It's obviously gray and yellow, and it's disgusting to look at.

A salt worker couldn't help but put a pinch of hot salt into his mouth.

"hiss!"

In an instant, a pure salty taste without bitterness spread on his tongue.

That taste made him nostalgic, and he was even reluctant to swallow the saliva.

Seeing that Yanto's expression, the people next to him couldn't help reaching out to pinch a little salt into their mouths in surprise, and then all of them showed wonderful expressions on their faces.

"good to eat!"

"It's not bitter at all..."

"It turns out that this is the taste of salt."

Sun Xin also tried to put a few grains of salt into his mouth, and tasted it slowly. To be honest, it was saltier than the table salt he remembered from his previous life. This should be because some potassium ions in sea salt were not absorbed. The reason was removed, but there was no sour or bitter taste. Sun Xin also sighed in his heart. After coming to this time and space for so long, he finally ate salt with only salty taste.

At this time, all the salt workers looked at Sun Xin as if they were looking at a fairy.

It only took one afternoon to produce such a bowl of good salt, which is something that is not even in a dream, not to mention that it is far more than this pot, and there is a whole pool of brine next to it.

The salt from these brines must be of such quality!
In an instant, all the regrets these salt workers had about coming to Niugang Village disappeared. If they could make such salt in the future, they would not even dare to think about the future of Niugang Village!

Xie Bao finally settled down when he saw the bowl of white salt, he knew that Master would definitely not leave him in Haizhou and leave him alone!
Sun Xin said to Xie Bao: "The port of Niugang Village is too small. It is impossible for our big ships to Haizhou to detour to Niugang Village, and only small boats can come. Therefore, each ship can carry The caustic soda and sulfuric acid are not too much, and the salt production of your Niugang Village in the future is estimated to be on this scale, but try to be as refined as possible.”

Sun Xin never thought of getting involved in the private salt business in Dengzhou. Although this business is highly profitable, it cannot be made bigger.

Moreover, most of the profits of the salt industry are due to monopoly rather than the result of industrialization. The idea of ​​cultivating a group of monopoly capitalists is inconsistent with Sun Xin's supervisory committee.

However, the fine private salt in Niugang Village is the only way to make a fortune here.

Xie Bao nodded, "Of course I know this. Master, don't worry, I will definitely build this place. In the future, we will be the first-class refined salt production area in Haizhou."

A smile finally appeared on Xie Bao's face, and Sun Xin patted him on the shoulder as an encouragement.

Sun Xin had no time to wander here, so he stayed for one night and returned to Dengzhou with the fleet the next day.

Seeing Master's boat heading north, Xie Bao felt a little empty in his heart, but when he thought of the salt-making method left by his master, he felt that his subordinates had the confidence. If the Supervisory Committee of Niugang Village cannot be set up, then it really cannot be justified!
He turned around and organized the farmer to expand production. Seeing that the next batch of salt merchants would come again, he had to fulfill the original promise of self-sufficiency for two months.

Xie Bao didn't even want to let go of the brine in the small salt pond, so he directly asked people to mix sulfuric acid and caustic soda into the brine in the small salt pond, experimenting with a simpler method of salt production.

On the other hand, iron prison pots were set up. He felt that it was too late just to dry the salt. He even took a few mouthfuls of the iron pots and rice cookers used for cooking in the village, and set them up to cook by the sea.

Li Cai went back to Huairen after collecting salt last time, and this time he also returned to Lanshan with the salt dealer.

He took those private dealers together to collect the salt from their Lijiazhuang. Li Cai thought that he and Xie Bao might not see each other for a long time, so he came to Niugang Village with the salt merchants.

He originally thought that Jie Bao, who was full of anxiety before he left, should have been tormented by the heavy and hopeless labor at the moment, and his farmer was probably as dead as his farmer in Lijiazhuang.

So when he saw the radiant faces of everyone in Niugang Village, he couldn't help but feel a little puzzled.

Xie Bao took out a pack of salt as white as snow, and the salt merchant and Li Cai were all stunned.

"You guys did this? How is it possible?"

Li Cai knew before that all the people in Niugang Village came from Dengzhou, and they felt uncomfortable after drying the salt here. He originally wanted to observe the neighbors with the mentality of watching fun, but now he wants to do it no matter what. I don't understand how Jiebao and the others came up with such a bag of fine white salt.

Could it be that they made this bag of salt during this period of time?

But no matter how you look at it, none of his dealers are in this state, doesn't it make sense?

They are all people in the industry, and everyone naturally knows how much work it takes to make such salt.

"How do you sell this salt?" The salt merchant suddenly showed an interested expression on his face.

Xie Bao opened his mouth and said, "It's the same price, one hundred coins per catty."

The salt merchant and Li Cai who heard this price were all tongue-tied.

There were three salt merchants who came, and one of them directly shook his head and said, "This price is too high, only pure Wu salt dares to sell at this price, your salt is good, but I'm afraid it's not as good as that Wu salt, right? "
