Daming One Piece

Chapter 62 I gave the rice (Second update, please recommend, please collect)
The location of the salt field is by the sea, about [-] miles away from the estuary. This is because the seawater in the estuary is fresh, so a certain distance is kept.

After the fleet exited the estuary, it sailed south along the coast.

When the boat sails by the sea, it looks very bumpy.
This was Shi Yiwen's first time sailing on the sea in such a small boat, feeling the impact of the waves, standing by the side of the boat, looking into the distance, he couldn't help but start thinking about the future.

When that ship is built, it must go to sea.

Go to sea, go to sea to get riches!

Like the Europeans in this age, go to sea to get riches, land...

……

More than an hour later, at the temporary noon, the fleet finally arrived at the salt field, which is actually an open space by the sea, where there are still the waste stove and grass shed left by Zheng Zhifeng's cooking last time.

However, because Yang Tiansheng and others came here earlier, there are dozens of simple bamboo houses on the beach.However, after disembarking, Shi Yiwen did not go to rest, but went to the nearby mud flat with Yang Tiansheng and others.

"Young Master Shi, look, this is the salty soil beach. The reason why Zheng Laosan chose to cook salt here earlier is because of the salty soil here..."

Yang Tiansheng pointed to the mudflat by the sea and said.

"Those glowing white spots are salt. We only need to dig out these salty soils and rinse them with sea water to make brine..."

In fact, there is no need for Yang Tiansheng's explanation. Shi Yiwen also knows what's going on. The ancients discovered a long time ago that after the sea tide ebbs, the surface water on the beach gradually evaporates, and salt crystals will precipitate out, especially when the sun is shining and the sea breeze is blowing. On a sunny day with more obvious transpiration, large salt crystals form on the dried beach. At a glance, it looks like it has just snowed.

Although the salt crystals formed on this beach are not that exaggerated, they are indeed quite a lot.Zheng Zhifeng and the others scrape up the salt crystals on the surface of the coastal beaches and the wet sediment rich in seawater below, and use salty soil to make brine.This is the experience summed up by the ancients, which is more time-saving than directly using seawater to make brine.

"Well, then what?"

Shi Yiwen asked.

"Then it's natural to burn the fire and boil the salt."

Yang Tiansheng said quite proudly.

"When I was young, I went to the salt field. I saw how they used sea water to wash the salt soil. We can build a salt pan here, pile up salt soil in the salt pan, and then divert seawater and salt soil, and then close the gate to block the water and re-pile the soil. Exposure to the sun, building a dam to irrigate the tide, and closing the gate to block the water. After repeating this several times, we can get the most concentrated brine, and then we can drain the brine away with ditches. He Zheng Laosan uses a local method, which is definitely not as good as ours. This method, I dare say, with this method, we can make at least ten thousand catties of salt a day, and then we can just harvest grass and cook salt..."

In order to emphasize his ability, Yang Tiansheng specially emphasized.

"Young Master, I have also heard that the lotus is tested for this brine, that is, the lotus seeds are used to test the brine. The thicker the brine, the more firewood will be saved. Saving firewood means saving labor and time..."

In fact, Yang Tiansheng is definitely a layman when it comes to making salt, but he did sell illegal salt when he was young, and he also saw some worldly things in the salt field, but he just heard about some methods of making salt, but even so, he thinks Others may not know as much as he does.

As for Zheng Zhifeng's method, it is nothing more than a "local method".

"Save labor and trouble?"

Shi Yiwen didn't pay attention to the pride on Yang Tiansheng's face, but said directly.

"Why use firewood if you want to save labor and time?"

"How do you cook salt without firewood?"

Yang Tiansheng was surprised.

"Boil the salt? Why boil it?"

Shi Yiwen continued.

"Even if you use salty soil to make brine in this way, you can make a thick brine, and then cook the salt with firewood, how long does it take to cook a pot of salt? How much firewood do you need?"

"this?"

After thinking about it, Yang Tiansheng said.

"You have to try it to find out. By the way, my lord, we have a few guys who cooked salt with Zheng Laosan. They may know how much firewood to use."

Then he pointed to the endless trees and weeds in the distance and said.

"Besides, we have so many trees here, and the grass is as tall as a person, so we don't have to worry about firewood. My son doesn't know that there are tens of thousands of acres or even 10,000+ acres of reeds planted beside the salt field, which are specially used for cooking pots and boiling salt. , it doesn’t need to be so troublesome here.”

"Isn't it troublesome to cut grass and trees?"

Glancing at him, Shi Yiwen said.

"Since we can get strong brine out of the sun, why can't we put it in the sun for a few more days, for ten days, ten days, if this continues, the brine will be dried, and the rest will be salt!"

In an instant, Yang Tiansheng was dumbfounded, he looked at Shi Yiwen in astonishment, and murmured.

"But, can this be done? This, can salt be produced in this way?"

"Why not?"

Shi Yiwen replied casually.

"It's that simple?"

After thinking for a while, Yang Tiansheng realized that what Shi Yiwen said made sense. Since he can dry out the salty soil, he must also be able to get out the salt.
"It's not that simple, there are still some small details in it, but right now..."

Pointing at the mud flat, Shi Yiwen smiled.

"The most important thing is that we have to build a salt pan for drying salt. This salt pan is similar to the one you just mentioned, but it has a larger area, and it is a cascaded salt pan with different heights. The sea water is first borrowed from the tide. In the salt field at the base, after being dried into brine, it is led to the second layer of salt field through the gate..."

Recalling the salt fields he visited, Shi Yiwen has almost formed the concept of a salt field in his mind, and he even observed the topography of this area specifically, the topography is high in the north and low in the south.

"Look, there is a drop of one or two meters from the north to the south. Let's use this terrain to build the salt field, but we need to build a dam over there. I don't know how high the tide is here. If the tide is suitable, we can directly use it to build a salt field. The sea tide fills the salt fields..."

For an engineering student, even if drying salt is not Shi Yi’s major, many principles can be understood at a glance. Moreover, the tour guide explained all this when visiting the salt field, so it is naturally easy to understand now. , but he did not expect that Yang Tiansheng and others were astonished by his own explanation in return. They were even a little stunned, and could not accept such a salt-making method for a long time.

"This, this sea water is brought in by the tide, and then let down layer by layer by the terrain, until the end..."

The dumbfounded Yang Tiansheng said in astonishment.

"Doesn't it mean that we can even make this salt with just a few people? This is a gift from God!"

Shi Yiwen rolled his eyes.

What God sent food to eat, obviously I sent it!
