On June 8, the weather was getting hotter and hotter, and after lunch, Su Ming took Ma Xingwang and Chen Jian to the salt factory.

Ma Xingwang saw that there was no one inside and outside the salt field of the Nuoda salt factory, only two people were on duty at the gate of the salt fort, and everyone was busy in the fort, which felt very strange.

"Eighth master, didn't the salt farm boil salt today?" Ma Xingwang asked.

"It's supposed to be cooking! Calculate the timeToday should be the day when the salt pan No. 3 is boiling, and you see the smoke on the salt fort. Su Ming pointed to the sky above the salt castle and said.

"Boil salt, why don't you see workers picking brine? Your salt pans are quite large, but the roads between them are too narrow. In this way, if there is a leak, it will affect the entire salt pan. Ma Xingwang said from a professional point of view.

"Master Ma, Master Chen, I'll take you to see our salt pans!

We have renovated the salt pans today, and the small salt pans along the coast are our old salt pans, and this year we are building new salt pans with cement in the back, you can see..."

"The brine from these nine old salt fields can enter this new salt field through a special channel, and the purity of the brine in the new salt field is enough, we enter the third-level salt field outside the salt fort through this channel, and the third-grade salt field is directly connected to the salt boiling room in the salt fort, and the workers can directly take the salt water in the fort to boil, so that the labor intensity is reduced by half." Su Ming didn't hide it in the slightest, and said to Ma Xingwang.

"This cement is really powerful, it can lead the salt water directly to the salt boiling room, but the eighth master, in order to set up another big salt field behind these salt fields, and finally set another salt field after these five big salt fields, is there anything special about this?" Ma Xingwang asked if he didn't understand.

"I'm so much! The salt content in our seawater is probably less than half of it. Su Ming said and looked at Ma Xingwang, who nodded.

"All the small salt pans in front of this, because of the direct connection with the sea water, when the tide rises and falls, new sea water is often mixed in, and the purity of salt in the salt pan is generally very good, and the time is at least half a month.

We know that the longer the salt is dried, the worse the water quality will be, and the worse the quality of the boiled salt will be, and using the two-stage salt drying method, we generally only dry the first-level salt field for seven days, even if its purity is only one percent, we will send it to the second-class salt field to dry.

The salt water in the second-class salt pans is necessarily much thicker than the seawater, and because it is only seven days, it is much clearer than the ordinary salt pan water.

When it comes to the second-grade salt pan, the bottom here is all cement, which is very clean, so it is impossible to increase the impurities, only to precipitate to make the brine clearer, so that in another seven days, the purity of the brine will reach 30% or even very high. Su Ming said.

"More than thirty percent? Doesn't the brine crystallize in this way? Ma Xingwang said in surprise.

"Yes, we usually let the salt pans start to crystallize before we take the brine, so that it will be easier to boil the salt.

After the brine of this secondary salt field is taken, we will clean up the sediment at the bottom in time, so that the quality of the brine can be guaranteed. Look at the last third-level salt pan! ”

Su Ming brought everyone to the gate of the salt castle, these salt fields are not big, only more than two acres in size, Chen Jian and his subordinates don't know anything about what Su Ming said, they don't know how to boil salt, the second horse is prosperous and can't look seriously, and anyone can see the excitement in their hearts.

"Even if the salt pan starts to crystallize, not all the brine is the same. In order to improve the efficiency of boiling salt, we have established a tertiary salt pan, which is this small salt pan.

Because this salt pan is small, the salt water mix is much better than the large salt pans. Do you see the salt crystallized here? If there is no crystallization, it means that the brine concentration here has not yet reached saturation. If there are too many crystals, it may affect the flow of brine into the salt boiling shed, and then you need to put some low-purity brine in, so that these crystals are almost dissipated, and then you can continue to take brine. Su Ming explained to Ma Xingwang.

"Wonderful, wonderful, really wonderful, this is really a genius idea, so that the efficiency of salt drying in the salt pan will reach the limit, the labor intensity of the workers will be reduced, and the consumption of firewood will be reduced to a minimum." Ma Xingwang understood Su Ming's new Yantian principle and clapped his hands happily.

Chen Jian and his subordinates didn't know why Ma Xingwang was so excited, didn't he just build a new salt pan, flow salt water here, build a few more canals, and give them cement and they could get it out.

"Eighth Master, can we take a look at the salt boiling room?" Ma Xingwang asked, pointing to the gate of the salt fort.

"Let's go!" Su Ming led Ma Xingwang and the others into the salt castle, and many people here greeted him when they saw him.

The salt fort has been built so far, a circle of houses 36 are now inhabited by workers, the central three areas of the fort, the first salt water filtration area, all the salt water must be filtered first, a total of four large filter screens are six layers, there are about more than ten workers working here, because the terrain in the fort is reasonable, the workers have been simplified to the limit.

The second area is the Ming Salt Boiling Room, which I call the No. 1 Salt Boiling Room, which is a large transparent factory, in which more than 40 cauldrons are half used, and the workers pick out the filtered salt water from the snowflake salt shed to boil.

The third area is the Snow Salt Shed (the second salt cooking room), which is also a large factory, but the surrounding area is not open, and it is blocked by some white cloth. Su Ming originally built a wall here, but it turned out that everyone boiled salt in it too hot, and finally dismantled it and used a white cloth to block it.

The fourth area is the salt collection area, where all the salt crystals are transported, crushed, filtered, and sieved out the required particles, and there is also a warehouse where the collected salt is placed.

"Su Xiucai, Master Ma, you are busy with me, go to the beach outside the fort and take a look!" Chen Jian felt bored after following for a while, he couldn't understand the salt boiled here, and it was very uncomfortable to stay here.

Chen saw that he was leading people to protect the salt factory, and he didn't know anything about technology, and when he heard the conversation between the two, Chen Jian felt very bored and went out of the salt fort to patrol.

Chen saw that he was gone, and Ma Xingwang came to a cauldron, looked at the salt crystals in the pot and paused for a breath.

"Eighth Master... You also salt doesn't seem to be the right color, why is it so white? Ma Xingwang came to the salt, which was almost cooked, turned his head and asked.

"Ah! This is snowflake salt, in addition to boiling enough salt for Yao Qianhu every month, the rest are boiled into snowflake salt, so that you can make more money, otherwise how to raise so many people in Erweibao, how to build Erweibao? Su Ming said lightly.

"Snow... Snowflake salt? Can this snowflake salt be boiled out of seawater? Ma Xingwang's two eyes glared at the boss, looked at Su Ming and asked.

"I was given a secret recipe to boil snowflake salt by special filtration of seawater. In this No. 2 salt shed, there is something specially filtered. Su Ming said and walked towards the No. 2 salt boiling room.

Ma Xingwang looked at Su Ming, his face changed drastically, why did Su Ming tell himself such an important secret, he let himself see the secret of filtered salt water turning into snowflake salt, would he kill himself?

But at this time, the other party lets himself in, is it okay if he doesn't enter? If you don't enter, doesn't it mean that you have a ghost in your heart? With apprehension, Ma Xingwang entered the No. 2 salt boiling room at the heaviest.

Fortunately, in addition to the normal pot stove here, there are rows of large water tanks behind it, some workers pour salt water into the water tank, salt water flows out from a bamboo space under the water tank, along a bamboo, flows into a cement tank, and the workers directly take water at the other end of the cement tank and pour it into the pot.

Seeing this new equipment, Ma Xingwang also figured it out, when he came to the Erweibao Salt Factory, Su Ming would never let him go, if he had to leave, it could only be a corpse.

I know the secret of Erweibao cement, this is nothing, I know the secret of the new salt field, Su Ming can pass this matter a little bit, but I know the secret of Erweibao snowflake salt, this is a big deal.

Since it has reached this point, then what should be done, anyway, Su Ming has no intention of killing him now, Yao Qianhu must not reveal the matter of Xuehua Salt, saying that Yao Qianhu may really tell others about this, and when the time comes, Xuehua Salt will be secretly leaked, if Jin Shanwei sends a large army to kill him, he will be the first to die.

"Eighth master, Erweibao salt factory is really unexpected, there is a craft in making snowflake salt, this must be not bad silver, I don't know how much snowflake salt this salt field can produce in a month?" Ma Xingwang thought that he already knew so much, and it was nothing to ask, he was really curious.

"The weather is good these days, 7 percent of the pots in the salt factory are open, and 35 stone of snowflake salt was boiled yesterday, and it is about more than 1,000 stone in a month!" Su Ming thought for a moment and said.

"What? How much? Ma Xingwang couldn't help but raise his voice, and the surrounding workers couldn't help but turn their heads to look at it.

"More than a thousand stones, isn't it?" Su Ming asked with a smile.

"Eighth Master, do you know how much a thousand stone snowflake salt is? No matter how cheap the snowflake salt on the market is, it will not be less than 700 wen a catty, one stone is more than 100 taels of silver, and 1,000 stones is 100,000 taels of silver!

The entire Songjiang Mansion does not have more than 100,000 taels of silver a year, and the 5,000 elite soldiers of Jinshanwei spend only 70,000 or 80,000 taels of silver a year. Ma Xingwang looked at Su Ming and said.

Su Ming smiled and said nothing, he felt that the salt cooking room was still too hot in this summer, so he walked to the yard, Ma Xingwang's mood didn't seem to have calmed down, and he followed him and stopped talking.

"Master Ma has something to say?" Su Ming saw Ma Xingwang come out and asked.

"Erweibao can't sell it even if it can produce so much snowflake salt, and there are few forces in Jiangnan that can eat so much private salt." Ma Xingwang said behind Su Ming.

"Yes, the salt can't be bad, just build a bigger warehouse, Erweibao can't use so much money every month now, but this salt will be bought sooner or later, isn't it?" Su Ming said.

Ma Xingwang knew the meaning of Su Ming's words, Erweibao would become strong sooner or later, whether he would choose Wang Zhi, these maritime merchants, or the family, or the imperial court is still uncertain, but as long as Erweibao has these snowflake salts, he will inevitably become stronger and stronger.
