Zhenguan Wenzong System

Chapter 291 Do you want the industrial Tang Dynasty?

"Sugar making."

Li Shimin was taken aback by Luo Yan's sonorous and forceful voice.After bragging for a long time, the co-author is talking about sugar making.How big is the contrast to make Li Shimin feel so hopeless right now.

"Jiangsu?" A suspicious voice spit out from Li Shimin's throat.

"That's right, it's sugar. What I make is not the brown sugar full of residues like today, nor the brown sugar from the Western Regions. When the time comes, Your Majesty will see the difference and know the difference. Oh , By the way, in the early stage, only five or six craftsmen are enough." Seeing Li Shimin's suspicious expression, Luo Yan could only tell his own plan.

Anyway, this big stick has already been put on Luo Yan's head, so he can make a fuss whatever he wants now.Li Shimin hurriedly wrote down the handwriting, stamped it with a big seal, and handed it to Luo Yan.

"Remember what you said, half a month's time, see the real chapter then."

Seeing that he had nothing to say staying here, Luo Yan took Li Shimin's handwritten letter and said, "Your Majesty will definitely not be disappointed. Your Majesty only needs to remember to give my minister a reward. If there is nothing wrong, Wei The minister retired."

"Okay, you go on your own." After finishing speaking, Li Shimin asked the left and right to send Luo Yan out of the palace.

"Father, can this Cheng Guogong really cure the queen mother's illness?" Princess Changle only opened her mouth to ask at this time.

At this time, Li Shimin finally lost the seriousness on his face just now, and said with a cheerful smile: "Changle, you don't understand, Luo Yan will never talk empty words. And any things that reach out to me for benefits will definitely make me happy in the end. "

Then he said: "And from what he said just now, you already have a draft in your chest, so we just don't want to believe it now. Well, it's only half a month, and it will be here soon, we just wait slowly .”

Not to mention the discussion of the three members of Li Shimin's family in the palace, Luo Yan couldn't help feeling a little excited as he held Li Shimin's warrant at the moment.

The ultimate goal of the sugar making I mentioned is to make rock sugar.The production process of this thing is quite simple to say, but in this day and age, it is impossible to manufacture it without using a lot of manpower and material resources.

Among other things, just a piece of white sugar can stump all the craftsmen in Datang.

Otherwise, brown sugar from the Western Regions would not be sold for hundreds of pennies per catty.The aforementioned caramel, which is the favorite of children, can only be bought for a catty of money, and there is no market for it.

The money-making thing that Luo Yan mentioned was this white sugar. If it could be produced, it would be sold to those merchants from the Western Regions along the Silk Road, not to mention the best-selling Tang Dynasty. It would definitely make a lot of money.

However, that is easier said than done.To make rock sugar, you must first solve the problem of white sugar.And to have white granulated sugar, the problem of decolorization must be solved.After much deliberation, under the current conditions, Luo Yan only thought of using the carbonization method.

The main advantage of this method is that raw materials are easy to find in Datang, and the only acid-base problem that needs to be solved can also be easily grasped by craftsmen through various physical characteristics.

After making up his mind, Luo Yan found the Ministry of Industry early the next morning.

Duan Lun, Shangshu of the Ministry of Industry, saw Li Shimin's handwriting and received Luo Yan very warmly.In addition to the craftsman written on the warrant, it is also promised but useful, and will definitely send people there at any time.Now, Luo Yan felt more at ease.

The Ministry of Industry also has a sugar cooking workshop appointed by the imperial court.Duan Lun took Luo Yan to the largest place under the control of the Ministry of Industry.The sugar used in the everything palace is basically from this workshop.

It was early spring at this time, far away from the sugar refining season, so when Luo Yan came, there was no one in the workshop except for a few craftsmen drinking and chatting.

Seeing their chief officer coming, these craftsmen panicked for a while, and the leader walked up to him, and hurriedly said: "Why is Shangguan free to come here today? I have no time for work, so I have some wine in the workshop." , and please forgive me, Shangguan.”

Duan Lun didn't want to blame this person for his clever words: "Okay, this is Cheng Guogong. By His Majesty's order, he came here to summon you to refine some things. During this time, you will follow Cheng Guo Your Majesty should reward you if you have achieved something."

"Shangguan, Your Majesty's reward is very good. However, we are only craftsmen who refine sugar, not pills. I am afraid that we will fail His Majesty's trust."

Duan Lun was about to scold, but Luo Yan stopped him: "Duan Gong, don't worry. That's it, I came here this time to refine some frosting sugar. You know the brown sugar from the Western Regions, I I found a way to make cleaner white sugar. So I need your help."

Several craftsmen all stood up at this time and exclaimed: "How is it possible?"

The method of making brown sugar was kept secret by the barbarians in the Western Regions. They didn't know it, so they thought the brown sugar was already amazing.Luo Yan actually said sugar at this time, how could they not be shocked.

"Is it true? You'll know if you try it. Well, let's not gossip, let's try it out today. Mr. Duan, I need twenty catties of brown sugar, lime, charcoal, sulfur, etc., please Duan Tolerance Give five catties each. Just before sunset today, I will let you make this white sugar yourself."

After hearing this, Duan Lun didn't dare to disobey his orders, but in just half an hour, he sent someone to deliver the corresponding materials.

With the detailed process of making white sugar by carbonization already in his mind, Luo Yan instructed the craftsmen to dissolve the brown sugar in water, and then filter out the residue in the brown sugar with fine gauze.Then began to use lime and burning charcoal to carry out preliminary precipitation in closed iron drums.

After repeating this three times, Luo Yan dipped his fingers into a trace of sugar water and rubbed it. He felt that it was almost done. Then he ordered the craftsman to start burning sulfur and continue to bleach in the closed iron bucket.As for the amount of sulfur, Luo Yan put it in strictly according to the data given by the system.

When the syrup is made, smoke it again with sulfur.Then officially start heating and boiling the syrup.

When making sugar for the first time, there was no material to help crystals, so that Luo Yan had to exchange a portion of powdered sugar from the system to add it.

Sure enough, at sunset, seven catties of refined white granulated sugar appeared in front of the artisans.

Although the white granulated sugar is slightly yellowed due to the crude manufacturing conditions, it is already many times whiter than the brown sugar sold by Hu merchants in the Western Regions.Those craftsmen carefully squeezed out a grain of sugar from the bowl, under the dim light, it was like looking at a rare gem.

"Now, are you convinced?" Luo Yan asked with a smile, looking at the craftsman in front of him.

"Grandpa is a strange person in the world, I am blessed in Tang Dynasty." After finishing speaking, these people actually knelt down in front of Luo Yan and kowtowed to him.

Help a few people, Luo Yan instructed. "You must have seen it today. Outside the gate are the Beiya Forbidden Army sent by the palace to guard the workshop. You must take good care of the sugar, and follow this method to make another hundred catties tomorrow. By the way, I will finally The powder placed here is made from this granulated sugar, so don’t forget it until the end. I’ll come to you the day after tomorrow to make the final thing to be refined.”

After saying this, seeing the craftsmen agreeing one by one, Luo Yan left with peace of mind.

Two days later, Luo Yan came to the workshop early, only to find that the craftsmen woke up earlier than him.Looking at the craftsmen gathered in front of several large iron pots, Luo Yan smiled and said, "Why, you still don't believe that sugar can be so white? Or, do you think that the boiled sugar is salt?"

"How dare I have such an idea. It's just that I did it again yesterday, and the effect is not as good as the one directed by my father-in-law. It's a pity."

"It's okay, it's just that there are some discrepancies in the various ratios. Maybe it's too much at one time, so the sulfur fumigation is uneven. Well, the things I'm going to trial today are very important, so we have to cheer up. "

Two conditions for making rock sugar, one is to add alum, and the other is to control the cooling temperature.After all, rock sugar is a small demand, and in Luo Yan's mind, only his eldest grandson Wugou can afford this thing, so what he needs is just a helper.

Melt the white granulated sugar and add the alum solution. When the syrup is boiled, it will be cooled and crystallized.This process takes about seven days, and it also needs to cool down in stages. With the current weather, it is definitely not something that ordinary workshops can do.

Fortunately, with the help of the system, Luo Yan finally got the rock candy out.And the price to pay is that I haven't slept well for several days in a row.When dozens of catties of rough rock sugar were placed in front of Luo Yan, he was already described as thin.Feeling that these were enough for the eldest grandson Wugou's needs for the next half a year or more, Luo Yan breathed a sigh of relief, called a Beiya imperial guard, put all these things into a bag, and then swaggered into the palace.

With this successful example, I don't have to suffer to continue refining after thinking about it.Just redeem it from the system.What I said before was actually just to find a suitable reason for Bingtang to appear.After all, this thing needs to let Li Shimin know that it is hard to come by.

Li Shimin summoned Luo Yan this time in the side hall of Tai Chi Hall.When he saw Luo Yan, whom he hadn't seen for ten days, looked haggard at the moment, he was shocked.

"Your Majesty was shocked. The humble minister lived up to his expectations and refined what he needed a few days ago. The detailed refining process was reported to His Majesty by the Imperial Army. This is the finished product and it is for the Empress. Prescription. Treat it according to the prescription. If you have any doubts, you can find someone who has the same symptoms as the Empress. However, this product is difficult to control. These are the dosages that the Empress has used for more than half a year. Please use it with caution."

After bowing to Li Shimin, Luo Yan looked sleepy, his eyes blinked twice from time to time, and his body shook twice.

Seeing this, Li Shimin didn't dare to ask more questions, so he hurriedly sent someone to send Luo Yan back to his residence.Along with them, there were also many nourishing treasures in the palace.

After doing all this, Li Shimin began to ask about the making process of this rock candy.
