The construction of Changlu Salt Farm is in full swing, because the salt drying method is very simple, the core is two kinds of pools, the evaporation pond should be closer to the sea, there must be a place where seawater waves can enter, and when building the embankment, the height of the embankment should be calculated.

Generally, the sea water in small waves cannot enter, and the sea water can only come in at high tide, so there is no need to drain the sea water.

Of course, you can also build a special aqueduct, open the aqueduct when needed, the sea water enters with the waves, and close the aqueduct when you don't need it, in the final analysis, it is actually the use of the law of sea water rise and fall to build an evaporation pond.

As for the crystallization pool, it is simpler, you only need to dig lower next to the evaporation pond to build a crystallization pond, and when necessary, the evaporated brine in the evaporation pond can be introduced into the crystallization pond for crystallization.

It can be said that there is no difficulty in the Haiyan Law at all, even if there is no Liu Jin, in another half a century, someone will come up with this thing.

Because of the seawater, it was not easy to build salt pans on the tidal flats by the sea, but with cement, these problems did not exist, so the construction speed was very fast.

Especially Liu Jin is willing to give up the capital, the salary is high, the food is also included, and there is meat for a meal, where can I find such working conditions?

What's more, now is the winter of farming, everyone is idle and has nothing to do, stay at home and cats winter, there are opportunities to make money, naturally a lot of people are willing to come over to do things.

Large, large expanses of tidal flats have been transformed into square salt pans at such rapid speed that there is no end in sight as far as you can see along the beach.

With the will of Emperor Hongzhi handed over, with the guarantee of the holy decree of today's son, the recruitment of workers on the side of Changlu Yantian is finally colorful, and under the attraction of treatment, these poor people in the coastal areas began to wear the uniform of Changlu Salt Field, and became busy on the salt field, becoming salt workers in the new era.

"Discharge water~"

On the ridge of a salt pan, the ridge is paved with cement, and the seawater is constantly beating on the ridge, Liu Jin, Tong Yuan, Li Jiye and others stand on the ridge, watching the salt workers open the aqueduct, with the fluctuation of the seawater, a large amount of seawater enters the evaporation pond along the aqueduct.

There is no need to dive into the water at all, just wave after wave, and in less than a stick of incense, the evaporation pond with a piece of face has been filled with seawater.

The next thing you need to do is to hand over to time, just wait slowly, waiting for the sun and the wind.

"In this winter, the temperature is too low, the efficiency is too slow, that is, the wind is strong, otherwise I doubt that I can dry the salt in winter."

Liu Jin stretched out his hand shrunk in the thick cotton jacket, and carefully felt the cold outside, at this time it was November of the eleventh year of Hongzhi, and it was very fast to celebrate the New Year, the weather was very cold, and the temperature had already dropped to zero degrees and more than ten degrees.

It must be difficult to dry salt at such a temperature, but the wind here is strong, and the wind is also an important magic weapon for drying salt.

A few days later, Liu Jin brought people to the evaporation pond again, and after a few days of wind and sun, he could clearly see that the water in the crystallization pool had dropped a lot.

"Master, the water has dropped by half, but it will take a long time to dry the salt."

Tong Yuan looked at a cement pillar next to the evaporation pond, the cement pillar has a specially carved length unit, and there must be a scientific data for everything, which is also the style that has been continued on the Xishan side.

The same is true for the Changlu Salt Field, all the salt pans are built according to uniform specifications, which is convenient for calculating the yield of the salt pans, and there are a large number of scales in the same evaporation ponds and crystallization ponds to calculate the water level, how much seawater is introduced, and how much seawater is evaporated.

When the water in the evaporation pond can be introduced into the crystallization pool, the water level in the crystallization pond needs to start adding chemical reaction things to remove impurities and so on.

These things are not good without accurate data, Liu Jin has always been extremely strict in this regard, whether it is Xishan Coal Industry, or many industries under his command, he has strict requirements in this regard.

Because there are many strict requirements, Liu Jin can easily calculate many things, and it is not so easy for these stewards under his hands to hide their words, of course, it is more important to cultivate a scientific spirit.

Now it is very extensive, but in the future, when the industry involved needs to be standardized and mass-produced, it will definitely not work without unified and scientific management, just like Tianjin Shipyard, which has almost harsh requirements in this regard.

Masters and apprentices in the shipyard must study mathematics, and if they don't meet the standards, they don't want to mix in the shipyard.

Tong Yuan looked at the evaporation pond in front of him, although the water was half less at this time, there was still no trace of salt.

"Don't worry, introduce this water into the crystallization pool, wait a few more days, we can start the harvest, don't look at the salt you can't see now, but soon, our salt will be piling up."

Liu Jin said very confidently.

Looking at the evaporation pond in front of him, he didn't expect that although it was a cold winter and the temperature was very low, the wind and sun were blowing, and in a few days, the seawater in the evaporation pond would evaporate badly.

This is indeed worthy of the famous Changlu Salt Field in later generations, this unique natural conditions, it is really not to say, even in winter, the temperature is low, there is the presence of wind, the evaporation of this salt field is still considerable.

In fact, as Liu Jin expected, a few days later, when Liu Jin, Tong Yuan, Li Jiye and others came to Yantian again, a thin layer of snow-white salt could be clearly seen in the crystallization pond, and the seawater had not yet evaporated, but the salt that came out could be clearly seen.

"Teacher, the salt is out~"

Tong Yuan excitedly went down to the crystallization pool and tasted the salt from the salt drying method, because Liu Jin added the steps to remove impurities in it, and the salt obtained was much better than the coarse salt boiled by boiling salt, not only the color was snow-white, but the particles were also finer, although it could not be compared with the snow salt that Liu Jin made the first pot of gold, but it was still a good salt in this era.

"This salt is definitely the best good salt ~ the taste is pure, there is no bitterness and astringency."

Li Jiye also made up his mind about these salts, and then looked at the salt pans that stretched to the end of the sea, and suddenly couldn't help but widen his eyes, and his mind was already imagining how much salt could be produced.

"This yield~"

Tong Yuan also seemed to have discovered this, carefully looked at the salt layer at the edge of the crystal pool, and then looked at the endless huge salt pan, and suddenly his mind was covered with countless salts, and then his eyes were full of white flowers and silver.

"It's not much now, wait until the beginning of spring, the weather will warm up, especially in the summer, if the temperature rises, hehe, at that time, when you really make money."

Liu Jin looked at the expressions of the two of them, smiled very satisfied, and said.

Although it's winter, it seems that the salt can still be dried, but the speed is a bit slow.

After a few days, the sea water in the crystallization pond has basically been dried, and the bottom of the crystallization pond has been paved with a layer, and the salt workers have begun to shovel out the salt and pile it up.

These salts also contain a lot of water, so they also need to be dried, and there are some solid impurities in them, which also need to be removed.

Where the salt was piled up, Tong Yuan, Li Jiye and others watched a load of salt continue to pick it up, and soon a snow-white salt mountain was piled up in front of them, and the whole person couldn't help but open his mouth wide.

"This salt drying method is really amazing, and the yield is so high~"

Li Jiye couldn't help but sigh, when I was experimenting before, I didn't think how powerful this salt drying method was, and the salt produced was not much, but who knew that now, when these salt pans began to be built one after another and put into use, the salt produced would be quite considerable.

It's just less than ten days, the salt produced in this salt field in front of you is piled up, this is still winter, if it is summer, the temperature is high, the sun is exposed, this yield will be very terrifying, it is estimated that by then, these three days are two ends of the salt mountains to dry out.

"The teacher is amazing, and the students admire~"

Tong Yuan directly threw himself into the ground for the five bodies that Liu Jin admired, the salt drying method is really feasible, and the yield is surprisingly high, so much salt is dried in the winter, if it is summer, I can't imagine it.
