Shen Kuo was holding a second citric acid-added candy in his hand and was about to put it into his mouth when he suddenly saw a mouse in the cage: "What did you mean just now? What does that mean? "

"Don't care about these details." Su You said to Shen Kuo: "This is a new industry that you have found in Meizhou! You can lose money by selling rock sugar and white sugar. Only by selling this can you make a big profit. Do you understand?"

Shen Kuo was immediately brought up the rhythm: "Yes! All these things are available in Meizhou! Such crystal sweet candies are not difficult to make, and they are the most suitable industry for Meizhou!"

After saying that, he shook his head and said, "It's too dark. You're like mixing water into sugar, and it can be sold more expensive than sugar!"

Shi Wei came in and saw the crystal fudge wrapped in the copper basin with frosting. She tasted one and smiled and said, "It's beautiful and delicious. The children will definitely like it. I will take it to Juzi Cang later."

Su You said: "This is just a test piece. I will go to the workshop to find a carpenter to make some small wood molds, and ask Master Zhang to use the latex of the land to turn it into a glue mold to shape the candy blocks. That is really beautiful."

Shen Kuo was anxious: "What are you waiting for? Let's leave now."

There is a lot of waste in the corners of the woodworking workshop. Su You took out a board and drew some heart-shaped stars, five-pointed stars, rabbits, turtles, puppies, kittens, lions, etc. on it. The carpenter saw it with a wire saw, polished it and stick it smoothly to another wooden board, and added the border to make a reverse mold frame, and sent it to Master Zhang together.

Shen Kuo saw Master Zhang take a white slurry and add some ingredients powder, mix well, pour it into the mold frame, and then pour the excess slurry out and repeat it several times, and then send the mold covered with a thick layer of slurry into a glass box, and then tinted a sulfur-scented incense into the box.

The additives of dibutylate glue are also a huge category. Master Zhang has been exploring for more than 20 years and has discovered many useful things.

Shen Kuo was also a curious baby, so he pulled Master Zhang to ask this and that. Before the day could finish his conversation, Master Zhang took out the wooden mold frame from the box. Shen Kuo found that the slurry that had just been poured into it had turned into an elastic solid.

Master Zhang stripped it off the wooden mold frame: "It's done."

Shen Kuoxi said: "I'll try it."

After making several more pieces of glue molds, Shen Kuo smiled and said, "This thing is good. What else can you do except mixing and making sugar?"

Su You lifted his feet: "Now it is a waterproof sole and a water pipe washer. In the future, it may be able to be used as a wheel."

After saying that, he said, "But it's too early to talk about those things, and the ginger grease grass is still in the promotion and planting stage."

Shen Kuo said: "If you want to run a candy factory, you have to at least hundreds of templates. Master Zhang, please let you get old."

Master Zhang smiled and said, "If it weren't for Mingrun, I wouldn't have thought of so many uses, so how could this brain grow..."

Su You said: "You can go back quickly after the things are finished. The rice will be harvested in the second season, and the planting will be planted again in the third season. By the way, there is another thing for you to bring, and you can use it to produce canvas."

He brought Shen Kuo to the machinery workshop, where there was a relatively small machine. The base was Shen Kuo's familiar foot drive equipment, but the one above was no longer a jade-carved mill or a porcelain turntable, but a cast iron guy, with a flywheel on one side and a needle on the other side.

This is a sewing machine.

The production technology of sewing machines is not difficult. With the current level of Meishan Seiko, there is no problem at all. This mechanical difficult-to-design coil sewing system.

The coil sewing method is very different from ordinary manual sewing.

In the simplest hand-stitching, the sewinger tied a thread in the small eyes at the end of the needle, then passed the needle and thread completely through the two pieces of fabric, from one side to the other, and then back.

In this way, the needle drives the thread into and out of the fabric and sews them together.

Although this is very simple for manual work, it is extremely difficult to pull with a machine.

The machine needs to release the needle on one side of the fabric and then immediately grab it again on the other side.

Then, it needs to pull all the loose thread out of the fabric, turn the direction of the needle, and repeat all the steps in the reverse direction.

This process is too complicated for a simple machine.

Su You didn't know the specific principles of the sewing machine. What he knew was that the sewing machine had a pressing teeth, and then the needle nostril was in the direction of the needle tip, and the needle was driven up and down to move up and down.

According to Su You's recollection, Meishan craftsmen made chain sewing machines, but chain sewing has a disadvantage, that is, although it can be sewn very quickly, it is not particularly strong. Once the knot at the end of the thread is loosened, it will cause the entire sewing thread to be loosened.

There was no choice but to ask Sitong Trading to list a reward of 500 jin to reward those who can solve this problem.

In the end, this problem was worshipped by Sitong Business Name, and the blue-eyed Qiu Niang solved it.

After Qiu Niang brought the knitting method of wool to the Song Dynasty, she also became a rich woman by opening a workshop of knitted sweaters, cotton socks and gloves.

The little rich woman arranged herself clearly and asked Shi Wei to find an orphan from the research institute to be her husband.

Without her mother-in-law and sister-in-law's discriminatory bloodline, the couple lived a beautiful life.

The researcher took on the research project of sewing machine coil sewing. After staying up for many days and nights, Qiu Niang discovered it and laughed at it hard.

What coil suture system is deliberately said to be foggy. Such a simple thing makes all you learners stump?

I tell you that this needle is similar to the crochet we use. Pull a thread on the other side of the fabric as a replacement for the sweater needle, and then design a steel ring to rotate to replace the human finger. So what is the so-called system? The first action of knitting with our women is the same?

So the problem was solved. The needle was pulled out a coil through the fabric. The rotating swing shuttle grabbed the coil with a crochet. Through the rotation of the swing shuttle, the coil was pulled into the new coil formed by the reciprocating movement of the needle to complete the sewing.

This kind of stitching is much stronger than chain stitching, which completely meets the needs of making canvas, cannon suits, and sacks.

This small ring with a notch in the key part, used to replace a human finger, is named the spiral shuttle.

The reward of 500 stag, which took so long but could not be solved, was easily solved by a girl who could wear sweaters!

Qiu Niang is not short of these 500 trump cards, but it is quite a happy thing to be able to help her husband earn a medal.

Su You talked about this case repeatedly at the Institute of Technology.

Look! What does it mean to pay attention to everything and learn? What is the importance of multidisciplinary linkage? This is a living case!

With the breakthrough of the spiral shuttle, other specialized sewing machines were soon invented.

In addition to this, there is also a leather sewing machine, which has also brought the production of leather goods into the era of sewing machines.

Leather goods move from manual to mechanical sewing stage, which can directly improve the military strength of the Song Dynasty.

Many of the equipment for horses and military equipment can be replaced by rivets to sewing, and the output of leather shoes can be greatly increased.

Shen Kuo was amazed at the design of the key components of the rotary shuttle, a sewing machine, and directly found Shizi to order twenty large and small sewing machines and sewing machines.

Just as the two discussed the recent mechanical achievements of the Polytechnic Institute, Sun Neng hurried over: "Master, Chameng is fighting! Bachelor Wang asked you to go to the shogunate to discuss!"

Su You said to Shen Kuo: "Let's go, Meizhou is also adjacent to Chameng, and Zhen La's reaction is also on the list of attention, and you are also there."

The three of them arrived at Ning Haijun, and the big guys were already waiting in the White Tiger Hall.

Su You strode to the military map: "What's the situation now?"

Wang Shao took the baton: "I just received news from Wang Zhen and the market affairs of Jiuzhou. He Li sent 30,000 troops and entered the three prefectures on the grounds that the land, Ma Ling and the governor did not obey the king's order and killed the officials he sent."

"Ludra fled to the Jiaozhi border and sought interference from the Song Dynasty."

"The local tyrant Zhang Lingcong, Liu Feng, and Huang Mu organized a clan Ding, who was called "Fengyan Army". He expressed his intention to obey the fire virtue and return to the Song Dynasty, and was unwilling to be a minister of Ludra and Heli again."

Su You nodded: "What is Wang Zhen's attitude?"

Wang Shao said: "Hali asked to borrow a city from Wang Zhen as a place where the Elephant Army was stationed, and at the same time, Wang Zhen provided food and grass for the people."

Su You smiled and said, "I'm doing a good job. Why don't he not send troops to help?"
Chapter completed!
