It is understandable that the salt produced by Wu is not as competitive as the salt produced by Qi, but in Qingji's view, this situation must be reversed.

First and foremost, the yield and quality of salt!

Therefore, this method of salt production must be changed, it must be produced in large quantities, and it can ensure high quality!

Immediately, Qingji asked the chief official of the workshop again, and said, "In addition to the decoction salt method, can't the workshop use other salt making methods?" ”

The official in charge replied: "My lord, there are several methods of salt production throughout the ages, none other than the method of frying salt, the method of sun drying, and the method of making brine from seawater. ”

"Haven't you considered any other means? Innovative salt production methods? ”

The official in charge smiled dumbly and said: "Your Majesty, this method of frying salt, drying in the sun, and making brine from seawater are all handed down by our ancestors, and they have been thousands of years old, and it seems that there is no other way to filter salt. ”

Hearing this, Qingji shook his head, these officials are really too step-by-step.

But it's no wonder that the source of ideas comes from life, and the ancients were able to have such wonderful ideas.

In the final analysis, it is actually to meet the needs of the times, just like the Taoist way of going with the flow, but it still needs to be improved.

As far as Qingji knows, the sun drying method is sun-dried, without going through the stage of decoction with firewood.

Its early production methods were: sun exposure, natural crystallization, and collective mining.

However, this method is obviously not suitable for mass production, and the quality of the salt produced is worrying.

At this time, Fan Li next to him asked tentatively: "King, could it be that the king has a better way to make salt?" ”

"Widows know a five-step salt production method that may be very suitable for salt production today."

Qingji was a vigorous and resolute person, he did what he said, he gathered a group of craftsmen in the salt workshop, and taught them the method of reclamation and drying, that is, the "five-step salt production method" that did not appear until the Tang Dynasty.

This five-step salt production method first appeared in Jindi, and was later extended to the production of sea salt.

In other words, this salt production method is suitable for the production of a series of edible salts such as sea salt, well salt, and pool salt!

The five-step salt production method, as the name suggests, is to produce salt in five steps: brine evaporation, removal of impurities, brine storage, crystallization, and shoveling.

Guy Qingji is not a professional saltsmith, so he only guides from the sidelines.

According to Qingji's instructions, the first step for the craftsmen to do is to collect brine and evaporate.

They lead the brine (water with high salt content) to the evaporation furrow, evaporate several sections, "one step at a time", and naturally evaporate with the power of the sun and wind.

When the brine is evaporated, it becomes a coarse salt with large granules.

Craftsmen began to remove impurities through the "basket", that is, the use of the salt plate crystallized in the process of salt production as a "basket", called the nitrate plate, which can remove impurities and purify the salt brine.

The third step is to store halogen.

The craftsmen will carry the brine after four to six "baskets" to the storage of brine and storage.

Then the brine was completely crystallized.

The bottom of the crystallization tank is a flat nitrate plate.

Before the brine is delivered, a small amount of fresh water is added to the pool to save manpower for shoveling salt, so that the combination of crystallized pool salt and nitrate plate is looser.

The craftsmen poured the brine from the storage brine into the crystallization pond to continuously precipitate the full and bright white salt.

This final step is to shovel out the salt and you're done!

The salt produced by this five-step salt production method has large particles, pure white color, and a bitter taste. It's definitely much better than the sea salt of Qi and the pool salt of Jin!

Qingji taught the method of pouring and drying the salt to the chief official of the workshop, and asked him to instruct the salt workers to operate.

As a superior person, it is naturally impossible to do it yourself. As the saying goes, there is a specialization in the art industry.

Let a person who knows nothing do this kind of technical work, and the whole work may not be as good as someone else's work for ten minutes!

The official in charge of the letter was suspicious and ordered the salt workers in the workshop to operate in accordance with the method of reclamation and drying salt taught by Qingji.

Less than two days later, a dish filled with large, pure white salt was placed in front of Qingji and the ministers.

Qingji immediately dipped in a little salt, tasted it, and immediately smiled and said, "Good! That's what it tastes like! ”

As the king of Wu and the king of a country, the salt he eats on weekdays is all high-quality refined salt, carefully selected salt.

And now, using the method of reclamation and drying salt taught by Qingji, it is completely possible to produce refined salt in large quantities!

After tasting a little salt, he suddenly looked flattering and praised: "King, this method of reclamation and drying salt is really extraordinary!" It is enough to sing the praises of the ages! ”

Hearing this, Qingji waved his hand and said: "The widow is determined to benefit the people, and the merits are evaluated by future generations, so why should the widow care?" ”

Qingji's words are quite hypocritical.

Gai Yin Qingji moved out of this method of reclamation and drying salt, in order to allow the salt produced by Wu to fully crush the salt produced by Qi in the market, so that Wu could make profits from it and make a lot of money!

"The king's invention of this method of making salt is a merit for the present and a move for the future! I'm afraid that Yao Shun can't do it, just this reclamation and drying method of salt, the king is enough to compete with Shennong's family! ”

I have to say that Bo Yan's kung fu has grown a lot.

Catching the shining point of the celebration is a burst of flattery!

However, Bo Yu is convinced by the reclamation and drying method invented by Qingji, except for a little bit of whiskers and horses, more worship!

Just imagine, salt is an indispensable condiment in every life.

Qingji improved the method of making salt, so that salt can be produced in large quantities without removing the bitter taste, thereby lowering the price of salt, so that more laboring people can eat enough salt.

Isn't that a great merit?

Qingji was a little fluttering by Bo Yan, and his old face was red, but he could still restrain himself.

Qingji immediately asked: "Second and third sons, how do you think the original salt frying method compares with the current reclamation and drying salt method?" ”

"This is a huge improvement!"

The official in charge lowered his hand and said, "My lord, the salt frying method in the past was time-consuming and laborious, and with the production capacity of salt making workshops in various places, the amount of salt that could be produced in a day was less than 600 stones. ”

"However, if you use this method of reclamation and drying to make salt, you can guarantee that the salt mills in various places can produce 1,000 stone of salt per day."

"And it's a conservative estimate!"

In this era, one stone is ten kilograms for the posterity.

Normally, a person should consume six grams of salt and two grams a meal, but in ancient times, they only had two meals a day, which may be a little less.
