At this time, these workers surrounded Zhao Feng and asked Zhao Feng all kinds of questions.
"Sir, will our wages still be the same as before?"
"Yes, I heard that the Li family sold all their ancestral property to the Liu family. Is this true?"
"You won't be able to pay your wages by then, right?"
Zhao Feng smiled and waved his hand and said to them.
"Don't you know about your family's situation? With such a big industry, how can it be possible for it to fall down at the drop of a hat?"
"You can just work hard and steadily. When the time comes, your wages will only be more than before, not less!"
Hearing Zhao Feng's words, the workers looked at Zhao Feng doubtfully, but at this time they had no other choice. After all, if they were driven away from the salt mountain, they would lose their livelihood.
So some workers stood up and shouted to the remaining workers.
"I think we should just believe this little brother's words first. Anyway, we know the character of the Li family and will not leave us alone!"
"You're right, everyone should keep working. Only by working hard can we help the Li family overcome the difficulties!"
The workers said this and quickly returned to the salt mountain to continue their busy work.
Zhao Feng sighed and walked over to take a look at the salt mines excavated by these workers.
Salt mine is not the salt that is hardened together in the conventional sense, but a stone containing salt. You only need to crush these stones, extract the salt with water, and finally dry it to become a common product on the market. brown salt.
After Zhao Feng walked over and took a look at these salt mines, he couldn't help but frowned slightly.
No wonder the quality of the Li family's salt is so poor, mainly because there are many substances in these stones that can be dissolved in water. They use water to extract the salt, and of course they extract these things together to form the impurities in the salt.
According to Zhao Feng's naked eye judgment, these substances should contain ingredients such as calcium chloride, iron oxide, and potassium sulfide. It is precisely because of these ingredients that the quality of Li's salt is so low after it is made.
Zhao Feng sighed. The Li family has been using this kind of salt for sale for many years. Most people in this era eat this kind of salt. Even when he first came here, he was poisoned by these salts. After a while.
In fact, it is not particularly difficult to remove the impurities in it. You only need to master the method of precipitation of each thing, and you can use some chemical means to extract the sodium chloride inside.
Zhao Feng looked at the workshops that produced brown salt and found that they just smashed the rocks and threw them into the water. They waited until the salt in the rocks dissolved in the water, and then took out the remaining insoluble stuff and threw it away. , and finally put the water into the salt pond to dry it out.
This made Zhao Feng shake his head, walked over directly, and said to them.
"Is this how you extract the salt from this?"
"Let me tell you a way to better extract these salts!"
The workers in the workshops looked at Zhao Feng in disbelief, while Zhao Feng directly frowned and said to them.
"Why are you standing there stunned? I was specially invited by the Li family to help you!"
"If you don't listen to me, then leave now!"
Upon hearing this, the workers had no choice but to curl their lips and said to Zhao Feng.
"Well, since you were invited here by the Li family, then we will listen to you and see what clever tricks you have!"
Zhao Feng waved his hand and asked the workers to get some firewood and a large iron pot for cooking.
Then, he poured the very turbid salt water into the iron pot and began to heat it continuously below.
As Zhao Feng continued to heat it, the temperature of the water began to slowly rise, and some impurities began to precipitate.
Zhao Feng used a relatively fine mesh to remove the impurities inside, added some salt water to it, and then continued to heat it.
Seeing Zhao Feng boiling a pot of salt water here, many workers came over curiously to watch.
After Zhao Feng boiled it for a while, the water inside began to steam slightly. Zhao Feng tried to test the temperature with his fingers and found that the water had now reached more than 50 degrees.
It is very simple to test the temperature of water with your fingers. Generally, water around 50 degrees will make people feel hot just now. Water at 60 degrees can only last for a second or two at most. Water above 70 degrees will not last long as long as you put it in. Once inside, people will subconsciously take their hands out.
Since there was no thermometer, Zhao Feng could only try this way.
After Zhao Feng fished out all the impurities in the water, he went to search for the things they had fished out before. He quickly found some stones that contained more calcium, and then threw all the stones away. After entering the water, it begins to replace the iron in it.
After the iron was replaced, a layer of reddish brown appeared on the removed stone, but the pot of water became clearer and translucent.
Zhao Feng continued to heat up, and the calcium inside slowly precipitated. If there are acidic substances, it would be better to add some to it.
In fact, the way to purify brine is very simple. It is to use various elements that are easily produced by water-soluble elements to add other elements, so that they can form water-insoluble substances. After these substances are fished out, what is left in the end is It is relatively pure sodium chloride brine.
Zhao Feng extracted all the substances that could easily affect the taste, and the entire brine became very clear and translucent, which made the workers nearby look at this scene in shock.
Zhao Feng increased the firepower and continued to cook. Soon the water in the pot began to boil. As the water vapor continued to rise, more and more impurities were precipitated out.
Zhao Feng quickly fished out all the last impurities, leaving only a pot of salt water. As he continued to boil, some white salt appeared on the wall of the pot.
Zhao Feng continued to heat until the salt water became very thick, then he breathed a sigh of relief and slowly extinguished the fire, letting the remaining heat of the pot evaporate the water inside.
In the end, what was left at the bottom of the pot was a whole piece of snow-white salt!
Seeing the snow-white salt, the workers around them were amazed. They never thought that there was such a way.
"This, what is this?"
"Yeah, what on earth is this?"
Zhao Feng turned to look at them and said with a smile.
"This is very pure table salt. You can taste it and see if this salt has any other flavors!"
Zhao Feng's words made the workers widen their eyes in disbelief. They had never seen salt of this quality before!
Soon some unbelieving workers came over and wanted to have a taste.
