"Sugar. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Luo Yan's sonorous and powerful voice made Li Shimin stunned. After blowing for a long time, the co-author is talking about sugar making. How big does this contrast have to be to make Li Shimin feel so loveless at this time.

"Sugar?" The voice of doubt spat out from Li Shimin's throat.

"Yes, it's sugar. The things made by Weichen are not the brown sugar full of residues today, nor is it the brown sugar from the Western Regions. When His Majesty saw it, he knew how big the difference was. Oh, by the way, in the early stage, Weichen only needs five or six craftsmen. Luo Yan saw that Li Shimin was suspicious, so he could only put his plan together.

Anyway, this big stick has already been put on Luo Yan's head, no matter how he makes a fuss now. Li Shimin hurriedly wrote down a handwritten letter, stamped it with a big seal, and handed it to Luo Yan.

"Remember what you said, the half-moon period, and see the real chapter when the time comes."

Seeing that he had nothing to say about staying here, Luo Yan took Li Shimin's handwritten letter and said, "I will definitely not disappoint Your Majesty." At that time, His Majesty only needs to remember to give Weichen a cut. If nothing happens, Weichen will retire. ”

"Alright, you can go yourself." After finishing speaking, Li Shimin asked Luo Yan to be sent out of the palace.

"Father, can this Chengguo Gong really cure his mother's illness?" Princess Changle only opened her mouth to ask at this time.

Li Shimin finally lost the seriousness on his face at this time, and smiled happily: "Changle, you don't understand, Luo Yan definitely doesn't talk empty words." And anything that reaches out to me for a favor will definitely make me happy in the end. ”

Then he said: "And you have already had a draft in your chest when you listen to his words, so we just don't want to believe it now." Okay, it's only half a month, and it's coming soon, so we'll just have to wait. ”

Not mentioning the discussion of Li Shimin's family of three in the palace, Luo Yan was holding Li Shimin's warrant at the moment, and he couldn't help but feel a little excited.

The ultimate purpose of sugar production is to make rock sugar. The production process of this thing is quite simple, but in this day and age, it is impossible to make it without using a lot of manpower and material resources.

Not to mention anything else, just one white sugar can stump all the craftsmen of Datang.

Otherwise, I wouldn't let the brown sugar from the Western Regions sell for hundreds of dollars a pound. The children's favorite caramel mentioned before, a pound can only be bought for several dollars, and there is no market.

The thing that Luo Yan said to make money is this white sugar, if you can get it out, not to mention the best-selling Datang, you can definitely make a lot of money by selling it to those merchants in the Western Regions along the Silk Road.

Easier said than done, though. To make rock sugar, we must first solve the problem of white sugar. To have white sugar, the problem of decolorization must be solved. Thinking about it, under the existing conditions, Luo Yan only thought of using the carbonization method.

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

made up his mind, and early the next morning, Luo Yan found the Ministry of Industry.

Duan Lun, the secretary of the Ministry of Industry, saw Li Shimin's handwriting and received Luo Yan very warmly. In addition to the craftsmen written on the warrant, they are also promised but useful, and they will be dispatched at any time. At this moment, Luo Yan was even more relieved.

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

At this time, it was early spring, far from the season of sugar training, so when Luo Yan came, except for a few craftsmen in the workshop who were eating and chatting, there was no one in the workshop.

Seeing their chief official coming, these craftsmen panicked for a while, and the first person stepped forward and hurriedly bowed: "Why do Shangguan have time to come today, I don't have a construction period, so I will eat some wine in the workshop, and ask Shangguan to forgive me." ”

This person said smartly, and Duan Lun didn't blame much: "Okay, okay, this is the Duke of Chengguo, who was ordered by His Majesty to come here to summon you and others to refine some things." During this time, you will follow Cheng Guogong and do things. If you have achieved something, your majesty will reward you and so on. ”

"Shangguan, Your Majesty's reward is excellent. It's just that we are just craftsmen refining sugar, not refining pills, so I am afraid that we will not be entrusted by Your Majesty. ”

Duan Lun was about to scold, but was stopped by Luo Yan: "Duan Gong don't be annoyed. That's right, I'm here to make some frosted sugar. You know the brown sugar in the Western Regions, I have 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 Hu people in the Western Regions, and they didn't know it, so they felt that this brown sugar was already amazing. Luo Yan actually said white sugar at this time, how could they not be shocked.

"Whether it's true or not, you'll know if you've tried it. Okay, without further ado, let's try it today. Duan Gong, I need 20 catties of brown sugar, lime, charcoal, sulfur and other things, please send 5 catties each. At sunset today, let you make this sugar with your own hands. ”

Duan Lun listened, where did he dare to disobey his orders, but in just half an hour, he sent someone to send a pair of materials.

With the detailed process of making white sugar by carbonization already in mind, Luo Yan instructed the craftsmen to dissolve the brown sugar in water, and then use spun yarn to filter out the residue in the brown sugar. This was followed by the use of lime and burning charcoal for initial sedimentation in closed iron drums.

After repeating this three times, Luo Yan dipped his fingers in a trace of sugar water, and after squeezing it, it felt almost enough, and then he ordered the craftsman to start burning the sulfur and bleaching it in a closed iron bucket. As for the dosage of sulfur, Luo Yan put it in strictly according to the data given by the system.

After making the syrup, smoke it again with sulfur. Then the syrup was heated and boiled in earnest.

For the first time to make sugar, there was no material for the crystal, so that Luo Yan had to exchange a piece of powdered sugar from the system and add it.

Sure enough, at sunset, the refined seven catties of white sugar were placed in front of the craftsmen.

Although the white sugar is still a little yellowish because of the poor manufacturing conditions, it is already many times whiter than the brown sugar sold by Hu merchants in the Western Regions. The craftsmen carefully pinched a grain of sugar out of the bowl, and in the dim light, it was like looking at a rare gem.

"Now, you're convinced." Luo Yan smiled and looked at the craftsman in front of him and asked.

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

Picking up a few people, Luo Yan instructed. "Presumably you have also seen it today, outside the door are the Northern Ya Forbidden Army sent by the palace to guard the workshop. You must take good care of these sugars, and tomorrow according to this method, you will make another hundred catties. By the way, the powder I put in the end is made by grinding this sugar, so don't forget it until the end. The day after tomorrow, I'll come back to you again to make the final thing to be refined. ”

After saying this, seeing that the craftsmen agreed 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 had actually gotten up earlier than him. Looking at the craftsmen gathered around several large iron basins, Luo Yan smiled and said, "Why, you still don't believe that sugar can be so white?" Or do you think it's salt that comes out of boiling? ”

"Where do I dare to think like this? It's just that I did it again yesterday, and the effect is not as good as what my grandfather commanded, so it's a pity. ”

"It's okay, it's just that there are some discrepancies in the various proportions, maybe it's too much at one time, so the sulfur smoke is not even. Okay, it's important for us to try out something today, but we have to cheer up. ”

There are two conditions for making rock sugar, one is to add alum, and the other is to control the cooling temperature. After all, rock candy is a small amount of demand, and in Luo Yan's heart, this thing can only be used by the eldest grandson, so what he needs is just to get started.

Melt the white sugar and boil it, add the alum solution, and when it is boiled to make the syrup, it will be cooled and crystallized. This process takes about seven days, and it also needs to cool down in stages, and 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 this rock candy out. And the price to pay is not sleeping well for several days in a row. When dozens of catties of crude rock candy were placed in front of Luo Yan, he was already a little thin. Feeling that these were enough for the needs of the eldest grandson for more than half a year, Luo Yan took a breath easily, called a Beiya forbidden army, put all these things into the bag, and then swaggered into the palace.

With this example, I don't have to suffer after I go back and forth and continue refining. Just redeem it from the system. The so-called before, in fact, was just to find a suitable reason for the appearance of rock candy. After all, this thing has to let Li Shimin know that it is not easy to come by.

Li Shimin summoned Luo Yan this time in the side hall of the Taiji Palace. When he saw Luo Yan, who he hadn't seen for ten days, was shocked when he described the withered appearance at this moment.

"Your Majesty was frightened. Weichen slept all night, lived up to the trust, and refined the things he needed a few days ago. The detailed refining process has its own forbidden army to return to His Majesty, which is the finished product and a prescription for the queen mother. According to the prescription, if you have any doubts, you can also find someone with the same condition as the queen mother to try it. However, this thing is difficult to make, these are already the amount of the queen's mother for more than half a year, I hope Your Majesty will use it carefully. ”

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 dared to ask more, and hurriedly sent someone to send Luo Yan back to the house. Sent over together, there are also many nourishing treasures treasured in the palace.

After doing all this, Li Shimin began to inquire about the production process of this rock candy. (To be continued.) )
