Chief don't slap in the face

The first workshop cave next to the utility room is only half the size of a basketball court. The ground is simply leveled, and there are some tools that the summer moon does not recognize.

"This is called a stone mill, and it is mainly used to crush grains and make them into powder or slurry!"

Carrying the bag on his back, Xia Ye walked to a stone platform, dug up more than a catty of wheat with a ladle made of sun-dried gourds, and poured it in along the mill.

"Oh"

Xia Lingyue looked at the stone mill curiously.

Its base is a large flat bluestone, about half a person's height, on which is placed a small disc ten centimeters thick and half a meter in diameter, and a disc of the same size is stacked on top of it.

On the disc, a half-finger-wide hole was cut out, that is, a grinding eye, and on the side, there was a groove opened, and a thick wooden stick was inserted.

"Don't pour too much wheat each time, just turn the stick!"

As Xia Ye exerted force, there was a creaking friction sound. Since it was in a cave, the sound was slightly louder and harsh.

"Wow!"

Xia Lingyue couldn't help exclaiming, the crushed wheat squeezed out from the gap between the two small discs and landed on the big bluestone.

While turning the stone mill, Xia Ye poured wheat into the mill, and soon, a lot of crushed wheat grains were piled up on the big blue stone.

"I come!"

Summer Moon was wise enough to gather them up with a broom and a wicker dustpan: "Is that all right?"

"This is just the first step!"

Xia Ye smiled: "Pass me the sieve over there!"

"sieve?"

Xia Lingyue has never seen this kind of tool before. It is made of bamboo strips, but it is not as dense as a dustpan, but has tiny holes like the eyes of a needle.

"Well, a farm tool that can filter out large particles of debris, leaving only flour!"

Xia Ye poured the groats into the sieve.

"flour?"

Xia Lingyue saw that with the shaking of her younger brother, large particles remained in the sieve, and a white powder fell down one after another like heavy snow.

"You can also call it wheat flour!"

Xia Ye collected the flour, then poured the crushed wheat into the mill eye for the second grinding.

Seeing the white flour increasing little by little, for some reason, Xia Lingyue's mood improved inexplicably, with a strange sense of satisfaction.

Half an hour later, ten catties of flour was obtained!

Xia Ye drank water, while Xia Lingyue squatted next to the big clay pot, admiring the wheat flour inside, which was white and soft like fine sand.

The touch is simply amazing!

"I really want to sleep in it!"

Xia Lingyue sighed with emotion, but then frowned again, her eyes fell on those yellow skins: "One stone of wheat yields less than [-]% of the wheat flour, what a waste!"

"This is called bran. It tastes bad. It can be used to feed mules and horses!"

Xia Ye thought of the old society. Poor people were willing to buy two catties of white bread dumplings only during the Chinese New Year. They usually ate coarse grains with bran and cornmeal, but that was better than ordinary people in this era.

"We don't have animals!"

Xia Lingyue grabbed a small cluster of bran and put it in her mouth, which pricked a bit.

"There will be bread, and there will be milk!"

Xia Ye joked: "Okay, let me tell you the principle of stone milling. Have you seen these textured grooves on the two discs? Extending from the center to the outside, from deep to shallow, they rub against each other and grind the wheat into flour !"

"My brother is awesome!"

When Xia Lingyue got excited, she hugged Xia Ye and kissed him on the cheek. It was a very simple truth, and it was obvious when she explained it, but there was a strong taste of wisdom in it.

You know, this is the first stone mill in the world.

"It's a pity that I don't have any money, otherwise I should send you to the Mohist academy, and you will definitely achieve great achievements in mechanism art!"

Summer Moon sighed.

"Forget it, I don't want to be a craftsman!"

Xia Ye pouted, no matter how powerful the mechanics of this era are, can they build fighter jets?So try to become a respected great wizard!

"Do not make progress!"

Xia Lingyue tapped Xia Ye's forehead with her fingers, and prepared to grind some flour by herself, but after scooping up a scoop, she suddenly froze. She found that she was only paying attention to the stone mill just now, and ignored a big problem: "These wheat What about the shell on it?"

"Here, that's called a stone mill, and it's used to dehull grains!"

Xia Ye didn't bother to show off, this thing really doesn't have any technical content, no kid who grew up in the countryside has never seen it before!

A platform made of several stones, on which there is a stone plate with a radius of more than one meter, with a hole in the middle, and a wooden stake placed vertically.

A cylindrical stone roller, placed on a stone plate, is fixed by a frame made of several pieces of wood so that it will not fall when rolling.

"After the grains have been crushed, use a dustpan to lift them against the wind, and the hulls are basically removed. If there are animals grinding, it can save a lot of effort!"

Xia Ye filled some noodles in a clay pot, poured water on it, and kneaded it into a dough. While the noodles were resting, he went to the vegetable field behind to pluck a few green onions.

"What is this for?"

When Xia Ye started cooking, Xia Lingyue ran over immediately, she was so curious.

"Baked scallion cake!"

Xia Ye shook a polished piece of wood: "This is called a rolling pin, use it to roll the dough into a half-nail-thick dough, and then brush it with oil, it doesn't need much!"

"Uh-huh!"

Xia Lingyue nodded hurriedly. This yellow viscous thing is called vegetable oil, which is forced out of peanuts by an oil press machine made by my younger brother out of wood.

This kind of oil is fragrant and fragrant, and the oil press machine with a simple structure is all invented by my younger brother.

Thinking of this, Xia Lingyue felt a strong sense of pride, the Xia family is both ruined?Hmph, I should be, but my brother is definitely not, he is a genius!

"Of course, it's also good to use lard, it's more fragrant, but if you eat too much, it's easy to get fat!"
