    "Bah~"

    "It still doesn't work. Although the salt has become thinner and no longer lumps, the taste is still very bad. This shows that there are still many impurities. How can we remove the remaining insoluble impurities?"

    A few days later, Liu Jin spit out a mouthful of bitter water. The freshly cooked salt still tasted bad. Liu Jin knew that the insoluble impurities in it were still there and had not been removed.

    But these days, Liu Jin has done nothing. He has been staying at home, researching and experimenting with many methods.

    "Lime water contains alkaline, so it should be able to react with some impurities in it and remove some of the impurities. Is it because both parties are very stable and no chemical reaction occurs?"

    Liu Jin touched his chin, a little crazy. He really regretted that he didn't study hard. This chemical effect is very powerful. If he had studied chemistry more seriously, purifying coarse salt would not be the same as Zhang Fei eating beans.  , a piece of cake.

    "It seems that I can only try the last method. I don't know if the China on the tip of my tongue is a lie."

    Soon, Liu Jin started experimenting again.

    The reason why he was confident that he could purify coarse salt was because he had watched China on the Bite of the Tongue while watching TV. One of the episodes talked about the mining of Zigong well salt in Sichuan. One of the details was about grinding soybeans into soy milk and adding  Boil it in the salt brine. In this way, the impurities in the brine are removed, thereby obtaining extremely pure salt.

    This method is a method summed up by the working people who have mined well salt in the Zigong area for 2,000 years. The quality of Zigong¡¯s well salt has always been very high, especially after the middle and late Qing Dynasty, the well salt here has been processed through various methods.  After purification, the purity has almost reached over 99%, and it is no different from the salt eaten by future generations.

    But Zigong Well Salt uses brine collected from the ground, and the sea brine he uses from the seaside. The impurities contained in the two may be different. Liu Jin is also very worried about whether this method is useful for sea salt.

    ¡°No matter what, let¡¯s give it a try first.¡±

    Liu Jin is a man of action. He took the soybeans bought by Zhao Erhu to the stone mill nearby and started grinding soy milk.

    "There should still be calcium in the soy milk. After the soy milk is ground, it must undergo a chemical reaction with the brine in a boiling state."

    While grinding the soy milk, Liu Jin carefully recalled the documentary episode he had watched in his mind. Although the Zigong well salt is well salt, in the end, the salt is boiled out through the process of boiling. There are many things in it.  They are all worth learning.

    "Brother Jin, what's been going on with you these past few days? Why have you been messing around at home and not reading? Is there something wrong with you?"

    While Liu Jin was grinding soy milk, Mrs. Wang walked in. Seeing Liu Jin starting to mess around again, she couldn't help but ask.

    She is very worried now. Doctor Zhang said last time that although Liu Jin is recovering, he is very likely to have some sequelae due to his head injury, so he may behave abnormally.

    "Mom, I'm fine."

    "Didn't I tell you that I'm studying boiling salt?"

    Liu Jin smiled and said.

    "What else do you need to study about boiling salt? Just go to the beach and see if it's enough. You've cooked it in the past few days and poured it into the water. You've also added some weird things to it. I don't know what you're messing with.  Well, if I have the time, I might as well read a few more books and try to go to high school next autumn."

    Mrs. Wang shook her head as she spoke. Although her son's behavior was a bit weird, she loved Liu Jin very much, so she let Liu Jin mess around here.

    "The salt I cook is different from other people's salt. You will know when the time comes. This is how our family will get rich in the future."

    "As for Qiu Wei, it's still early, so I can read the book slowly."

    Liu Jin didn't take it seriously and told himself to read ancient books. It was still the Four Books and Five Classics. They were really boring. After reading them for a few times, he felt like sleeping. It was probably impossible to take the imperial examination path.

    However, Liu Jin did not dare to tell Wang directly like this, otherwise Wang would definitely pick up a broom and beat Liu Jin severely no matter how much she loved Liu Jin. She had always worked hard to raise Liu Jin and provide for her.  When he studied, he didn't expect Liu Jin to be able to get ahead by studying.

    ¡°She will never give in on the matter of studying.

    "It's up to you, you make your own arrangements, I'm going to work in the fields."

    Mrs. Wang looked at Liu Jin, shook her head, and didn't care.??, the name is just nice to hear.  "

    Zhao Erhu looked at the salt in the pot and said in a naive manner.

    "Huzi, this snow salt is related to our future fortune plans. You can't say anything to anyone without my permission."

    Liu Jin nodded, then thought about it and warned Zhao Erhu.

    Although the snow salt has been boiled, Li Jin also knows that the benefits are attractive and he has no roots and power. If he wants to make a fortune, he must keep this secret.

    Of course, only Liu Jin himself knows how to purify coarse salt into refined salt. Even Hu Zi next to him can't figure it out.

    "To expand production capacity in the future, we will definitely need more manpower, and we must have trustworthy people. We must also separate these steps. Each one is only responsible for one step. It is best to add some useless links to increase the number of others.  The difficulty of spying on secrets.¡±

    Soon, Liu Jin's mind began to think of some things to do later. There was no way. Liu Jin was now relying on this method of purifying coarse salt to make a fortune. Of course, he had to take good care of his way to make a fortune.  Keep.  (Remember the website address: www.hlnovel.com
