Chapter 581: Multi-Layered Salt Ponds, Producing A Million Pounds Of Salt In One Day [Please Subscri
Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, who were also standing on the coastal embankment, followed the direction pointed by Yan Changqing and looked into the distance.
What caught their eyes were patches of red, yellow, green, pink, blue, brown...the overall display of colorful salt pools.
Seeing this scene, Prince Zhu Biao asked with curiosity:
“Why do these salt ponds show such colorful colors?!”
Yan Changqing smiled and said:
"This is because in the process of extracting sea salt crystallization, the concentration of salinity and crystallization speed of each salt pond are different, so different colors are formed.
"For example, when the sea water is just introduced and has not changed color, it is a blue salt pond."
"After drying, the algae in the seawater turn green after multiplying, and it becomes a green salt pond."
"As the concentration of salt in the salt pond increases, the algae die and the bodies rot, turning into a yellow salt pond."
"As the concentration of salinity further increases, it contains a large amount of calcium and magnesium ions, and with the reproduction of salt worms, it will turn into a red salt pool." 193"
"In addition, the oxidation of metal ions, the reproduction of microorganisms, and the angle of sunlight will also cause the salt pond to show different colors."
Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes all nodded in confusion after hearing Yan Changqing's explanation.
Although I don’t understand it very well, just know that this is normal.
Yan Changqing continued:
"After the multi-layer salt pond is repaired, it is time to proceed to the final steps of brine production, crystallization and collection."
"Seawater flows into the reservoir through submarine pipelines, and then passes through seven layers of salt ponds for layer-by-layer sedimentation, evaporation and concentration."
"Finally, after evaporation and concentration in the first five layers of evaporation pools, it flows into the sixth layer and begins to crystallize, and finally forms salt on the seventh layer!!!"
"And this process is also called the 'seven-step water' method of making sea salt."
"If there are continuous sunny or windy days, then seawater will be released from the reservoir to the multi-layer salt pond, and finally dried to make salt."
"The whole process usually takes three to four days, or even two to three days to complete the drying of sea salt.'
"If there is a persistent cloudy day, then seawater will be released from the reservoir to the multi-layer salt pond, and finally dried to make salt."
“The whole process only takes about five to seven days, which is enough to complete the drying of sea salt.
"If there is continuous heavy rain, then seawater will be released from the reservoir to the multi-layer salt pond, and finally dried to make salt."
"The whole process takes about seven days to half a month to complete the drying of sea salt."
"If it is only temporary, such as a cloudy or rainy day that only lasts for a day or half a day, and then it is sunny again.'
"Then the whole process usually takes three to four days to complete the drying of sea salt."
"In general, the drying of sea salt is closely related to the weather."
"The better the weather and the stronger the wind, the faster the sea salt will be dried, and vice versa."
"Whether it is covering the multi-layered salt pond with a glass cover or using foot-operated windmills on both sides of the multi-layered salt pond, the high-concentration seawater in the multi-layered salt pond is often blown."
“The purpose is to eliminate as much as possible the adverse weather effects on the production of sea salt and expand the favorable weather and environmental effects on the production of sea salt.
Normally, if it is an ordinary multi-layer salt pool without a magnifying glass to focus and heat up.
If the weather is good, it will take about seven to ten days to dry it into salt.
If the weather is bad, it will take about half a month to a month to dry it into salt.
The glass cover he laid out and the use of a magnifying glass to focus the heat increased the efficiency of drying into salt by nearly half.
However, this method can only be used in this era and under the leadership of the national court.
Otherwise, if it were in the past life, let alone the method of making salt that was better, more efficient, and more productive than drying salt in salt ponds in many counties.
Just for the glass cover covering the entire salt pond and the tens of thousands of glass magnifying glasses, the cost of glass consumed is beyond the reach of ordinary people.
And in this day and age, what is glass?!
Isn’t that made of sand?
How much is the sand worth, not to mention that the sea sand used is locally sourced!!!
Therefore, in the eyes of Zhu Yuanzhang, the water was in the eyes of the ten princes including Crown Prince Zhu Di, Zhu Di, Zhu Nan, and Zhu Di.
Liuli is equal to sand, and sand is equal to worthless, so we come to the conclusion that colored glaze is equal to worthless.
Although this conclusion of value recognition is wrong, it can be regarded as wrong or wrong.
At least under this misunderstanding, Zhu Yuanzhang, as well as the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes were willing to use colored glaze.
In their view, even if the entire multi-layered salt pool on the seashore is covered with a glass cover, it will only be a waste of labor costs and a small amount of other raw materials to assist in firing the glass.
The money required is not much, so there is no feeling of distress in the process of using or wasting the colored glaze.
This is why Yan Changqing in this era was able to use the sea salt drying method that would have been considered extravagant, wasteful, and even mentally ill in later generations.
The princes Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes on the side all nodded after listening to what Yan Changqing said.
At this point, they have a general and clear understanding of the entire process of drying sea salt.
Then, King Qin Zhu Di asked the question they were most concerned about:
“How much sea salt can these multi-layered salt ponds produce now?!!”
After all, whether the Ming Dynasty can realize the freedom of eating salt depends on how much sea salt this seaside salt pond can produce...
As long as this seaside salt pond produces a huge amount of salt, the Ming Dynasty will quickly build similar seaside salt ponds in other coastal areas.
"Nowadays, the last layer of sea salt in multi-layer salt ponds can produce at least 10,000 kilograms of sea salt per mu of land every day on average!!!"
"The sea salt salt formation pool covers an area of ten acres, and can produce at least 100,000 kilograms of salt in one day!!!"
"And there are a total of twelve multi-layered salt pond sea salt production units like this in the entire sea salt drying area [which means that at the end of the day, at least ten acres of land and ten square meters of land can produce salt!!"
Yan Changqing said with a faint smile.
After hearing the amount of salt produced in one day reported by Yan Changqing, Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes immediately made calculations in their hearts:
[At least 1.2 million kilograms of salt can be produced in one day. In other words, at least 36 million kilograms of salt can be produced in one month?!!]
[Then wouldn’t it be possible to produce at least 432 million kilograms of salt in a year?!!]
[If I remember correctly, the total amount of salt cooked by all the kitchen households in the Ming Dynasty in a day and night is only over 1.6 million!!!]
[The salt quota set by the imperial court is more than 459.94 million kilograms of salt per year!!!]
[Then doesn’t it mean that even if the imperial court abolishes all kitchen households now, just relying on the sea salt produced in Haizhou City will be enough to supply the current needs of the people of the Ming Dynasty?!!]
[And this is just the sea salt production in Haizhou City in one year!!!]
[If nine such sea salt production areas were built in other coastal areas of the Ming Dynasty, wouldn’t the Ming Dynasty really be able to produce 12 million kilograms of salt a day in the future?!!3.5]
[Tens of millions of kilograms of salt can be produced in one day. The gentleman was indeed not lying!!!]
Looking at the shocked expressions of Crown Prince Zhu Biao, Zhu Xi, Zhu Fan, Zhu Di and other princes, Yan Changqing added in a leisurely tone:
"According to future plans, the sea salt drying area will be further expanded to 6,000 acres next year, and then twelve more multi-layered salt ponds like the current one will be built."
"This means that if the plan goes well, Haiyan will double its current amount by this time next year!!!"
As soon as these words came out, Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes all widened their eyes, with only one thought in their minds:
[His grandma produces nearly one billion kilograms of salt in one year?!!]
