The whole family of villains criticized her wildly, but the princess treated her with medical treatm

"This grain windmill can sort out at least five hundred kilograms of rice in one hour!"

"It's much better than traditional winnowing and dustpans."

"Her Royal Highness the Princess is a great talent!"

There were a doctor from the Ministry of Industry, a foreign doctor from the Ministry of Works, and a field doctor. They also held ink fountains, axes, files and other tools for making windmills in their hands. There was sweat on their foreheads from a whole day of hard work, and their eyes were shining with excitement. .

They are all fifth- and sixth-grade sesame officials. It is basically impossible for an official of this level to interact with the eldest princess of the first-grade prince level. It is difficult to say a word, let alone to be like this now. They ate and sat together and jointly developed the windmill.

Everyone felt very honored in their hearts.

If you brag about this experience to your colleagues, you can brag about it for several years.

The Marquis of Qin was a very rigorous mechanical master. He studied the grain windmill for a while and made a suggestion: "Would it be better to design two grain outlets?"

Mu Tingxue raised her eyebrows: "Oh?"

Her brother-in-law is really a talent. She didn't even draw it. He thought of the windmill with two grain outlets that is still in use in the countryside.

"Your Highness, you see, the principle of this grain windmill is that due to the different weights of grains and debris, they are blown to different places by the wind and separated. But when we restored it, there were errors in the actual operation."

The Marquis of Qin shook the fan and pointed inside, "The grains do not all fly to the same place. There are grains that are full, the best and heavier, and there are grains that are inferior and lighter. The third part is the impurities and chaff that fly out." .”

Mu Tingxue smiled and said: "What the Marquis said makes sense, add another grain outlet to separate the fine grain from the secondary grain."

Yuanyang frowned slightly and said: "For most farmers, there is no need to divide it so finely. A grain windmill at the grain outlet is enough. What kind of family would pay attention to the fullness of the rice grains? It is not easy to have enough food. Moreover, with two grain outlets, the cost will inevitably increase. The price of grain windmills has also gone up, and ordinary people cannot afford it."

Although she is a girl, the drawings of the Gufengmill were drawn in her hometown of Zhujia Village.

The minister of the Ministry of Industry came over with a few assistants to get wood to make it on the spot, and she was also present.

"What Yuanyang said makes sense. Your starting points are different."

Mu Tingxue did not deny either side, "For ordinary people, a grain windmill with a single grain outlet is more economical and practical; but for rice merchants, grain merchants, and aristocratic families with a large number of fields, a grain windmill with two grain outlets is more economical and practical. The windmill makes it easy to select the best refined grains, stratify grain prices, and provide the rich refined grains to rich people who have high quality of life requirements."

The Marquis of Qin had darker skin and a toothy smile, which made him look honest and honest: "Then according to His Highness's wish, we can make both types of windmills."

People from the Ministry of Industry were having another intense discussion.

Appropriate modifications were made to the original drawings provided by Mu Tingxue, and a second grain outlet was added.

The first double-output grain windmill we built was not rigorous enough and malfunctioned. It was immediately scrapped and started over. It wasn't until the sky turned dark that the second perfect double-output valley windmill was finally made!

For testing purposes.

Yuanyang packed a full sack of sun-dried rice mixed with impurities from the ground in front of his house and carried it over.

The girl is very energetic and can carry it on her own.

A sack of rice poured into the funnel of the windmill.

The Marquis of Qin was manually operating on the side, and the fan blades rotated, and the chaff and rice husks flew out. The first grain outlet collected fine grains with heavier weight; the second outlet farther away from the fan From the grain mouth, all that is blown out are lighter and inferior grains.

"Success!"

Lord Qin was overjoyed and felt a sense of accomplishment.

Mu Tingxue also smiled: "We can do a lot of promotion among the people. Single-mouthed ones are cheaper."

The Marquis of Qin praised: "The screening efficiency of the double outlet is relatively high, and it can sift seven to eight hundred kilograms of grain in one hour. Your Highness has done another good thing for the benefit of the people!"

Mu Tingxue did not dare to take credit: "It is all the wisdom of the ancestors of the Celestial Dynasty."

In the 21st century, modern machinery processes grain much more efficiently than wooden grain windmills.

The efficiency of the Sanli compound concentrator in screening 3 to 5000kg of rice grains per hour is a breeze, and the screening area is very clean. This kind of wooden rice mill can screen 3 to 500kg in one hour, which is incredible, and the sifting quality is not special. clean.

Of course, we cannot ask the ancients to follow the standards of modern mechanization.

Hearing the word "Celestial Dynasty", several Ministry of Industry officials looked at the eldest princess, once again full of awe. What is sung in the nursery rhyme that the goddess is so powerful is not just a lie.

The two valley windmills were quickly put into mass production.

The Ministry of Industry has its own industry chain channels for craftsmen. Once a decree is issued, all craftsmen and craftsmen will take action.

A few days of effort.

On the streets and alleys, you can see many carpenter shops selling grain windmills.

And now, after the big harvest, it is the busy period of threshing millet and screening crops. The common people, grain merchants, and big landowners of aristocratic families all need such a convenient and efficient wooden wind machine.

Not expensive.

Because there are no special requirements for wooden materials, ordinary wood will suffice, and you can even cut a metasequoia tree on the mountain and make it immediately.

A single grain-kou valley windmill costs fifty coins.

Two windmills with grain rations, one hundred coins.

The price is relatively close to the people. Because the effect is good and it can be used for a long time, it can be seen on the street that many farmers go to carpenter shops to order and buy.

Some handy people in the countryside can even cut down trees and make their own.

At the request of the eldest princess, all agricultural tools that are widely promoted among farmers and common people do not engage in intellectual property protection and monopoly.

"Master, our carpenter at the entrance of Zhujia Village is also doing this."

Yuanyang leaned close to Mu Tingxue's ear, lowered her voice and said, "The price he offered is cheaper than in Yundu City. It only costs thirty cents. Just cut the wood from the mountain and prepare it for him."

Mu Tingxue said: "The masters are among the people, the really good old carpenters passed down from their ancestors. They can make this kind of windmill by themselves as long as they take it apart and look at it once or twice."

Yuanyang nodded vigorously: "Yes, Carpenter Lu is very good. Many people in the village come to his place to make furniture, but it's a pity that he is a lame man and is alone. When others proposed marriage to him, he refused, saying that he didn't want to. It hurts other girls.”

Mu Tingxue's heart skipped a beat.

"Your surname is Lu? Could it be that he is the successor of Lu Ban Shu?"
