The construction of the Changlu Salt Farm is in full swing, because the salt-drying method is very simple. The core are two types of pools. The evaporation pool should be closer to the seaside, and there should be a place where seawater waves can enter. When building a dam, the height of the dam must be
Calculate it well.
Normal small waves of sea water cannot come in. Sea water can only come in when the tide is high. In this way, there is no need to work hard to attract sea water.
Of course, you can also build a special diversion canal, open the diversion canal when needed, and seawater will enter with the waves, and close the diversion canal when not needed. In the final analysis, the law of the rise and fall of sea water is actually used to build evaporation ponds.
As for the crystallization pond, it is even simpler. You only need to dig lower next to the evaporation pond to build a crystallization pond. When necessary, the evaporated brine in the evaporation pond can be introduced into the crystallization pond for crystallization.
It can be said that the sea salt method is not difficult at all. Even without Liu Jin, someone would have come up with this thing in half a century.
Because of the sea water, it was not easy to build salt pans on the beach. But with cement, there are no such problems, so the construction speed is very fast.
Especially since Liu Jin is willing to invest capital, the wages are high, food is included, and meat is provided for every meal. Where can I find such working conditions?
What's more, it's the winter season when farming is slack, and everyone has nothing to do. Staying at home during the winter, there are naturally a lot of opportunities to make money, and a lot of people are willing to come over and do things.
Large tracts of tidal flats turned into square salt pans at an extremely fast speed. The salt pans are so continuous that you can't even see the end of them at a glance along the beach.
And with the decree from Emperor Hongzhi coming, and with the guarantee of the emperor's imperial decree, the recruitment of workers in Changlu Salt Field finally became more attractive. Attracted by the benefits, these poor people in the coastal areas began to wear long trousers.
The uniform work uniform of the Lu Salt Field has become a new era of salt workers as they get busy on the salt fields.
"Let the water go~"
On the ridge of a salt field, the ridge is paved with cement, and the sea water is constantly lapping on the ridge. Liu Jin, Tong Yuan, Li Jiye and others stood on the ridge, watching the salt workers open the diversion channel, accompanied by the fluctuation of the sea water.
, a large amount of seawater entered the evaporation pond along the diversion channel.
There was no need to bother diving into the water at all, just wave after wave, and in less than a stick of incense, the evaporation pool covering the face was filled with sea water.
The next thing to do is to give it to time, just wait slowly, wait for the sun and wind.
"In this winter, the temperature is too low, the efficiency is too slow, and the wind is strong, otherwise I doubt whether salt can be produced in the winter."
Liu Jin stretched out his hand that was shrunk inside his thick cotton-padded jacket and carefully felt the cold outside. It was already November of the eleventh year of Hongzhi, and the Chinese New Year was coming very soon. The weather was very cold, and the temperature had already dropped.
It's already over 0 degrees Celsius.
It is definitely difficult to dry salt in such a temperature, but the wind here is strong, and wind is also an important magic weapon for drying salt.
A few days later, Liu Jin took people to the evaporation pond again. After several days of exposure to wind and sun, it could be clearly seen that the water in the crystallization pond had dropped a lot.
"Teacher, the water has dropped by half, but it will still take a long time to produce salt."
Tong Yuan looked at a cement column next to the evaporation pond. There were specially carved length units on the cement column. Everything must have scientific data. This is also the style that has been continued here in Xishan.
The same is true when it comes to the Changlu Salt Field. All salt fields are built according to unified specifications to facilitate calculation of salt field production. The same evaporation ponds and crystallization ponds have a large number of scales used to calculate water levels and introduce
How much sea water has evaporated.
When can the water in the evaporation pond be introduced into the crystallization pond? When the water level in the crystallization pond reaches that level, chemical reaction materials need to be added to remove impurities, etc.
These things are impossible without accurate data. Liu Jin has always had extremely strict requirements in this regard. Whether it is Xishan Coal Industry or the many industries under his command, he has strict requirements in this regard.
Because there are many strict requirements, Liu Jin can calculate many things easily. It is not so easy for the stewards under him to conceal 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 require standardized mass production, it will definitely not work without unified and scientific management. Just like the Tianjin Shipyard, the requirements in this regard are almost harsh.
Both masters and apprentices in the shipyard must take professional studies in mathematics. If they do not meet the standards, they will not be able to survive in the shipyard.
Tong Yuan looked at the evaporation pond in front of him. Although the water was half gone, there was still no trace of salt.
"Don't worry, let's introduce this water into the crystallization pond. After a few days, we can start harvesting. Even though we can't see a little salt now, soon, our salt will be piled up like a mountain."
Liu Jin said very confidently.
Looking at the evaporation pond in front of him, he did not expect that even though it was winter and the temperature was very low, the seawater in the evaporation pond would evaporate greatly in a few days due to the wind and sun.
This is indeed the famous Changlu Salt Field in later generations. This unique natural condition is really unparalleled. 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 the salt field again, a thin layer of snow-white salt could be clearly seen in the crystallization pond, and the sea water was still there.
Not all of it has evaporated completely, but the salt that comes out can be clearly seen.
"Teacher, the salt is out~"
Tong Yuan excitedly went down to the crystallization pond and tasted the salt produced by the sun-dried salt method. Because Liu Jin added steps to remove impurities in it, the salt obtained was much better than the coarse salt produced by boiling salt.
, not only is the color 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 ~ it tastes pure and has no bitter taste."
Li Jiye also made a conclusion about the salt, and then looked at the salt fields stretching to the end of the seaside. He couldn't help but widen his eyes. He was already imagining how much salt this could produce.
"This output~"
Tong Yuan seemed to have discovered this. He carefully looked at the salt layer at the crystallization pool, and then looked at the endless huge salt fields. His mind was suddenly covered with countless salts, and then his eyes were filled with tears.
It's white money.
"It's not a big deal now. When spring starts and the weather gets warmer, especially in summer, if the temperature rises, hey, then you can really make money."
Liu Jin looked at the expressions of the two of them, smiled with satisfaction and said.
Although it is winter, it seems that the sun can still produce salt, but the speed is a bit slow.
After a few days, the seawater in the crystallization pond has basically dried, and a layer has been laid on the bottom of the crystallization pond. The salt workers began to shovel out the salt and pile it together.
These salts also contain a lot of water, so they need to be dried. In addition, there are some solid impurities in them, which also need to be removed.
At the place where the salt was piled, Tong Yuan, Li Jiye and others watched the piles of salt being picked over, and soon a snow-white mountain of salt was piled up in front of them. They couldn't help but open their mouths.
"This sun-salting method is really amazing, the yield is so high~"
Li Jiye couldn't help but sigh. During the previous experiment, he didn't realize how powerful this salt-drying method was, and the salt produced was not much. But who knows now, when these salt fields begin to be built one after another and put into use?
, the salt produced is quite considerable.
In less than ten days, the salt produced in 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, the output will be very terrifying. It is estimated that
At that time, mountains of salt were exposed every two days.
"My mentor is great and my students admire him~"
Tong Yuan immediately expressed his admiration for Liu Jin. The salt-drying method was really feasible, and the yield was surprisingly high. So much salt was produced in the winter, which would be unimaginable in the summer.
