Daming Town Haiwang

Chapter 320, Salt Mountain

The construction of Changlu Salt Field is in full swing, because the method of drying salt is very simple. The core is two kinds of pools. The evaporation pool should be closer to the sea, and there must be a place where sea waves can enter. When building a dam, the height of the dam should be To calculate well.

Ordinary small waves of sea water cannot enter, only when the tide is high, sea water can enter, so that there is no need to work hard to attract sea water.

Of course, special diversion canals can also be built. When necessary, the diversion canals can be opened, and the seawater can enter with the waves.

As for the crystallization pool, it is even simpler. You only need to dig a little lower next to the evaporation pool to build a crystallization pool. When necessary, introduce the evaporated brine in the evaporation pool into the crystallization pool for crystallization.

It can be said that the sea salt method is not difficult at all. Even if there is no Liu Jin, someone will come up with this thing in half a century.

Because of the sea water, it was not an easy task to build a salt pan on the tidal flats, but with cement, these problems did not exist, so the construction speed was very fast.

In particular, Liu Jin is willing to spend capital. The wages are high, meals are included, and there is meat every day. Where can I find such working conditions?
What's more, it's the winter of slack farming, everyone has nothing to do, stay at home, cat winter, there are opportunities to make money, naturally a lot of people are willing to come and do things.

Large, large areas of tidal flats turned into square salt pans at an extremely fast speed. The salt pans are endless. If you look along the beach, you can't see the end at all.

With the decree issued by Emperor Hongzhi, with the guarantee of today's imperial decree, the recruitment of workers in Changlu Salt Field has finally become attractive. Attracted by the treatment, these poor people in the coastal areas began to wear long clothes. The uniform work uniform of the Luyan Field has become busy in the salt field, and has become a salt worker in the new era.

"Let the water~"

On the field ridge of a salt field, the field ridge is paved with cement, and the sea water is constantly beating on the field ridge. Liu Jin, Tong Yuan, Li Jiye and others stood on the field ridge, watching the salt workers open the diversion channel, accompanied by the fluctuation of sea water , a large amount of seawater entered the evaporation pond along the diversion channel.

There is no need to strenuously dive into the water. It is just a wave after wave. In less than a stick of incense, the evaporation pool that is full of faces has been filled with sea water.

The next thing to do is to give it to time, just wait slowly, waiting for the sun and the wind.

"It's winter, the temperature is too low, the efficiency is too slow, that is, the wind is strong, otherwise I doubt whether the salt can be produced in winter."

Liu Jin stretched out his hand shrunk inside the thick padded jacket, and carefully felt the cold outside. It was already November of the eleventh year of Hongzhi, and the New Year was coming soon. The weather was very cold, and the temperature had already dropped. It's more than ten degrees below zero.

It must be difficult to dry salt in 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 pool again. After several 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 out the salt."

Tong Yuan looked at a cement pillar next to the evaporation pool. There are specially drawn units of length on the cement pillar. There must be a scientific data for everything. This is also the style that has continued on the Xishan side.

The same is true for the Changlu Salt Field. All the salt fields are built according to uniform specifications, which is convenient for calculating the output of the salt fields. The same evaporation ponds and crystallization ponds have a large number of scales to calculate the water level. How much seawater, how much seawater evaporated.

When can the water in the evaporation pool be introduced into the crystallization pool, when the water level in the crystallization pool reaches that position, it is necessary to start adding chemical reaction things into it to remove impurities and so on.

These things are impossible 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. It is not so easy for the stewards under him to hide themselves. Of course, the more important thing is to cultivate a scientific spirit.

It is very extensive now, but when the industries involved in the future need standardized mass production, it will definitely not work without unified and scientific management, just like Tianjin Shipyard, which has almost strict requirements in this regard.

Both masters and apprentices in the shipyard must take professional studies in mathematics, and if they fail to meet the standards, they will not be able to get along in the shipyard.

Tong Yuan looked at the evaporation pool in front of him. Although the water was reduced by half at this time, there was still no trace of salt.

"Don't worry, bring the water into the crystallization pond. After a few more days, we can start harvesting. Although we can't see a little salt now, our salt will pile up like a mountain soon."

Liu Jin said confidently.

Looking at the evaporation pool in front of him, he didn't expect that even though it was cold winter and the temperature was very low, the seawater in the evaporation pool would evaporate violently within a few days due to the wind and sun.

This place is indeed worthy of being the famous Changlu Salt Field in later generations. This unique natural condition is really undeniable. Even in winter, when the temperature is low and there is wind, the evaporation of this salt field is still considerable.

In fact, just 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 layer could be clearly seen in the crystallization pool, and the seawater was still there. Not all evaporated completely, but the salt that came out can be clearly seen.

"Master, the salt is out~"

Tong Yuan excitedly went down to the crystallization pool, and tasted the salt produced by the sun-dried salt method, because Liu Jin added the step of removing impurities in it, and the salt obtained was much better than the coarse salt obtained by boiling salt , not only the color is white, but the particles are also finer. Although it cannot be compared with the snow salt that Liu Jin made his first pot of gold, it is still a good salt in this era.

"This salt is definitely the best salt~ the taste is pure, without bitterness."

Li Jiye also came to a conclusion on the salt, and then looked at the salt fields stretching to the end of the sea, he couldn't help but widen his eyes, and he was already imagining in his mind how much salt could be produced.

"This yield~"

Tong Yuan seemed to have noticed this too. He carefully looked at the salt layer near the crystallization pond, and then at the huge and endless salt fields. His mind was immediately covered by countless salts, and his eyes were filled with tears. It is white silver.

"It's not a big deal right now. When the weather warms up after the beginning of spring, especially in summer, if the temperature rises, hehe, then it's time to really make money."

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

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

A few days later, the seawater in the crystallization pool was basically dried up, and a layer had been laid on the bottom of the crystallization pool, and the salt workers began to shovel out the salt and pile it up.

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

At the place where the salt was piled up, Tong Yuan, Li Jiye and others watched loads of salt being picked up continuously, and soon a snow-white mountain of salt was piled up in front of them, and they couldn't help opening their mouths.

"This sun-dried salt method is really amazing, and the yield is so high~"

Li Jiye couldn't help but sighed. During the previous experiments, he didn't realize how powerful this sun-dried salt method is, and the salt produced is not much, but who knows now, when these salt fields start to be built one after another and put into use , the salt produced is quite considerable.

In less than ten days, the salt produced by the salt field in front of me has piled up like a mountain. It is still winter. If it is summer, the temperature is high and the sun is exposed to the sun, the output will be very scary. It is estimated that At that time, mountains of salt were exposed to the sun at both ends of these three days.

"The teacher is amazing, the students admire~"

Tong Yuan directly expressed his admiration to Liu Jin. The sun-dried salt method is really feasible, and the yield is surprisingly high. So much salt can be sun-dried in the winter, which is unimaginable if it comes to summer.

　It seems that I can't do anything tomorrow, I can only code words with salted fish~
