In October, the weather was getting cooler, and the peach blossoms raised a ball of firewood in the courtyard, and an iron furnace was set up on it, which was also borrowed from a neighbor who was a wealthy man. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Jiangning is located in the lower reaches of the Shenlong River, located in the middle of the Grand Canal, connecting the north and south, with both the cold current of the cold day in the north and the humidity of the southern wetland, which makes the temperature of the whole Jiangning mixed with a trace of cold.

"Uncle Wang, smash the straw I collected in that cauldron into powder with a mallet."

For Uncle Wang, Sun Qi is grateful, during Sun Qi's scientific expedition, Uncle Wang came thousands of miles to accompany him, taking care of Sun Qi's daily life, protecting Sun Qi's personal safety on the road, and more, under Feng Chuan's recommendation, Uncle Wang found a job in Jiangning Iron Ore Factory, but when Sun Qi wanted to go back to rescue Sun Ziyan, Uncle Wang resolutely resigned, and he didn't take half a dime, so he continued the journey with Sun Qi.

Now he is acting as Sun Qi's subordinate and handyman, Sun Qi's heart has a touch, and he is always grateful to this man who tolerated himself for stealing a piece of iron at that time, if it weren't for him, I'm afraid I can't do it with the manufacturing drawings of a bicycle now.

"Okay, uncle, let's do it."

Uncle Wang's figure was boiling water, turned around and picked up a mallet, ready to mash the pure straw that Sun Qi had collected.

"Hey, hey, that fat man, slow down when you pound that pot, if you break it too hard, you will pay me for it, and that pot will cost half a tael of silver."

Peach Blossom complained on the side, her voice was fierce, but her eyes were very soft when she looked at the king blacksmith.

Peach Blossom walked over slowly, and she saw Sun Qi holding a drawing in his hand.

Of course, Sun Qi's drawings are just a disguise, otherwise it would be too sharp to pinch a briquette, and let this peach blossom sister-in-law's machine gun mouth go out, and no one in Kutou Village will know that there is a Taoist priest who can change items at will.

Sun Qi doesn't want this kind of sudden horror, he just wants to be a behind-the-scenes man, working before and after.

"Why is your briquette round?"

Sister-in-law Peach Blossom has been taking good care of the unconscious Sun Ziyan for the past few days, as if she was taking care of her own daughter, and has been cooking some hot porridge for this strange woman and feeding it to Sun Ziyan by hand.

Of course, she also has a biological son studying at Jiangning Wenzheng Academy, which is the county school.

"This, because the circle is more fire-free, round, a little and ten thousand paths are connected, this pattern is the most perfect pattern in the world, the square has dead corners, triangles and dead corners, only this circle, can be more generous, more comprehensive acceptance of the fire roasting, in order to achieve greater energy conservation and emission reduction, saving resources marginal effect....."

"Also, round like the road, round, has always been the pursuit of people lofty goals, is the desire of people's hearts, only round, flat around, in order to benefit all things without pause..."

Sun Qi didn't know what he was talking about in the end, he was talking nonsense, and he heard Peach Blossom Sister-in-law in a fog for a while, in short, Peach Blossom Sister-in-law, who hadn't read a few books, finally had a little understanding of the circle, isn't this just a wheel, you can roll further, or a pot lid, which can collect all the heat in the pot and buckle it, what are you doing so complicated, you are so good at reading, and I haven't seen you lifted.

Sister-in-law Peach Blossom taunted Sun Qi.

"Isn't it the season to release the list yet, there are still more than ten days before the laurel tree is fragrant, I don't have to guess to know that it is off the list."

Sun Qi said modestly, but the mashing of the straw in his hand did not decrease at all, the huge hammer made a 'bang' sound in the pot, and those yellow straws were vigorously compressed into powder in the pot.

"Boy, don't use too much force, you will have to pay if the pot is broken."

Sister-in-law Peach Blossom pretended to be angry.

Sun Qi nodded with a smile and said with a smile: "When the briquettes come out, I can let you buy hundreds of pots, and even if you want to buy all the pots in the world, this briquette can also help you buy them back." ”

Sister-in-law Peach Blossom cut it disdainfully, as if she was disdainful of what Sun Qi said.

When the straw in several large pots had turned into powder, Sun Qi and Uncle Wang threw all the large pots of powder into the blast furnace.

"Isn't there water in the blast furnace?"

Sister-in-law Peach Blossom was dressed in a dispersion and happened to be standing next to Uncle Wang, Sun Qi didn't know whether Sister-in-law Peach Blossom was standing beside Uncle Wang intentionally or intentionally.

"This step is called plasticization, you can't add water, add water and it will become a dry pot to cook straw, do you want to eat it?"

Sun Qi quipped, but the taste of cooking straw in a dry pot must be a little sweet, because the straw is all the residue left by the by-products of crops, and there is plenty of starch in it.

"Look at the cowhide looking at you in the sky, you keep blowing, don't let it fall."

Sister-in-law Peach Blossom couldn't get used to Sun Qi's profound reasoning, and thought that telling people who had never read a book was completely insulting her IQ.

"The fire under the bottom is going to burn vigorously, and the ignition point of the straw is 220 degrees, so add more firewood below, don't be afraid of burning."

The first step of plasticization is simple, but the next step is more troublesome.

Half an hour later, Sun Qi heard the sound of bubbles coming out of the blast furnace, which must have been straw porridge cooked.

Blacksmith Wang stepped forward to bring out the straw paste of a large stove, looking at this black thing all over the ground, Sun Qi was a little speechless.

If you want to ask why the yellow straw turns black, this is because after the high temperature burning, most of the straw has been carbonized, which is the basis of briquettes.

Now the black paste on the ground is the carbonized straw.

However, Sun Qi specially made a few coal lattices, that is, there are many circular holes in the board, and when pressed down, it is in the shape of a briquette.

"Sister-in-law, take it and press it."

Sun Qi pressed down on the black paste, and suddenly three or four briquettes came out.

Sister-in-law Peach Blossom was very disgusted by this black paste, covering her nose and saying, "Scholar, are you disgusting sister-in-law, why does this black thing smell so bad?" ”

"That's because the chemicals in it ...... volatile"

"Gotta get it, don't say it, my sister-in-law suspects that you are insulting my sister-in-law's IQ, haven't I never read a book, just press it, who is afraid of whom?"

Sister-in-law Peach Blossom broke the shackles and pressed the black paste with the coal maker, and several briquettes suddenly came out.

The three of them, facing the three large balls of black paste, tirelessly pressed the paste for an afternoon, and the peach blossom face of Sister-in-law Peach Blossom was smeared black, and Uncle Wang's complexion was originally dark, so it was no big deal.

But the results have also been very fruitful

"Scholar, do you do such a thing at home? Oh, sister-in-law, this person is old, and her body is not good, the blacksmith, let's get a wet towel to wipe our faces. ”

Sister-in-law Peach Blossom said weakly with her hands on her waist.

"Gotcha."

Uncle Wang went away in response and was extremely obedient.

"Sister-in-law, you're going to make a fortune tomorrow, aren't you happy?"

Sun Qi quipped that after plasticization, these formed briquettes can be put into the blast furnace for coking and carbonization, and what comes out is practical briquettes.
