"Hmm......"

After going around the world's first briquette furnace a few times, Li Yuanjia nodded with satisfaction, which was completely different from his reaction when he saw the second pot made by the blacksmiths before.

The briquette stove is something he can't be more familiar with.

Ahem, it should be said that it is another "Li Yuanjia", a Li Yuanjia who has lived in one of China's coal capitals since he was a child and is also used to dealing with coal. As a northerner, he has the impression that when he was a child, there was no natural gas at all, not even a gas tank, and every household cooked or heated in winter, relying on briquette stoves.

As for the briquettes, they all hit them themselves.

At that time, the salary of my parents was not high, and it added up to more than 100 yuan a month, and I was definitely reluctant to buy ready-made briquettes from others.

It's not just their family, it's basically everyone who did it back then.

Therefore, in Li Yuanjia's memory, in the family courtyard of his mother's factory, a large open space is neatly filled with briquettes, and the scene of the father and son next to him holding one of their own and a briquette machine borrowed from a neighbor's house and beating briquettes has become a memory that he can never forget......

The briquette stove in front of me, except that it feels a little bigger and the process is rougher, is exactly the same as in my memory.

"King, what's the use of you making this thing?"

"Hehe, what's the use?"

Glancing at Han Shan obliquely, Li Yuanjia shook his head and smiled: "Let me tell you, this thing is very useful!" Especially in winter, when you put it in the house, not only can you keep warm, but also have hot water to drink at any time, even if you want to eat a hot pot or something, as long as there are briquettes...... No way! ”

"Huh? What's wrong, King? ”

Han Shan was taken aback by Li Yuanjia's cry and asked hurriedly.

"Briquettes, briquettes...... There's no such thing as a briquette! ”

Ignoring Han Shan, Li Yuanjia suddenly thought of a very serious problem, that is, there is a briquette stove, but what about the briquettes? Or how to solve the problem of briquette machine?

Coal, yellow mud, water and hand-held briquette machine are the four essential elements for making briquettes.

Yellow mud and water are everywhere, and it's not a question of whether it's worth it or not, because it doesn't cost money at all. Don't worry about coal, because the ancestors used coal very early, some people used it as fuel at the beginning of the Han Dynasty, and some people used it to boil tea and drink it in the former Sui Dynasty, and Li Yuanjia also asked people to inquire before, there is indeed "charcoal" here in Luzhou, and it seems that there are quite a lot......

The question is, how to do a briquette machine?

The two blacksmiths in front of them can't even make a pot properly, and they are expected to make a briquette machine?

Don't be funny!

So when Li Yuanjia had a headache, a blacksmith named Shi Sheng boldly asked: "King, dare to ask what this briquette is?" Why don't you draw a picture and I'll help you create one? ”

After making the second iron pot, Shi Sheng's confidence also increased greatly!

Although this thing still can't get into Li Yuanjia's eyes, it's because he has seen real industrialized products in his previous life, the round ones are like drawn with compasses, and the thickness of the whole body is consistent, and the surface is even smoother than a fly...... Ahem, it's an exaggeration, but it's pretty. But during the Zhenguan period, the second pot created by several stone students can be regarded as a good craftsmanship, at least much more pleasing to the eye than the first one.

Especially seeing that the king seemed to be very satisfied with the furnace, Shi Sheng instantly swelled.

"Briquettes? Build? ”

After listening to Shi Sheng's words, Li Yuanjia was immediately happy: "That thing is not made of iron, how can you build it?" It's made of charcoal powder mixed with mud and water......"

It doesn't seem too easy to describe in words, Li Yuanjia simply waved his hand, asked Han Shan to go to his study and brought paper and pencils, and then drew them on the spot with a willow charcoal pen - since the first set of tables and chairs was made, Chen Mu has not stopped in the following time, making more than a dozen sets before and after, filling the places where Li Yuanjia usually stays. And the set of tables and chairs he uses now was just moved to this small courtyard two days ago.

So after drawing a sketch of the briquette with a willow charcoal pen, Li Yuanjia shook his head and said: "Actually, it doesn't look complicated, but the important thing is that it must be round, just enough to fit into the coal furnace, and there must be several holes, and the position of the holes on each briquette must be the same...... It's not easy to do! ”

“……”

After listening to the king's words, and looking at the figure on the paper in front of him, Shi Sheng was a little confused for a while.

As if he was afraid that he didn't understand something, Shi Sheng's eyes widened and he looked at it carefully over and over again, and finally couldn't help but say, "Great, king, if this thing you painted is made of charcoal powder, water, and mud...... Shouldn't it be difficult, right? ”

As a stone student, he was not ignorant of the charcoal powder that could be burned.

"Huh? Isn't it hard? ”

Regarding Shi Sheng's response, Li Yuanjia's eyes suddenly widened.

"Yes, King!"

Nodding boldly, Shi Sheng immediately bowed his head and apologized, picked up a piece of paper from the table, bent it into a circle, and then said respectfully: "We can make something like this, with a wooden board underneath, and then pour in something made of charcoal powder, mud and water, and when it is filled, cover it with a wooden board that has made holes, and then poke it with a wooden stick......

"Ouch, that's true!"

After watching Shi Sheng's demonstration, Li Yuanjia suddenly understood.

No, it's that simple!

Then with a slight grasp of his head, he knew that he had just drilled the tip of the horns - the biggest significance of the existence of the briquette machine is that it is simple to use, and it is extremely efficient, and a person can even punch thousands of briquettes a day! But without the briquette machine, it's no problem to do it by hand, but it's less efficient......

In these years, is the low efficiency a hair?

One person can only do fifty ...... a day What if it's even twenty? Could it be that he is a dignified prince, and there is still a shortage of manpower in the palace?

After discovering that he had a wrong idea, Li Yuanjia suddenly had a big brain, and waved his hand again and again: "If you want to look at it this way, you don't have to be so troublesome, you go back and make a few thick iron bars, and then fix them together, and just poke them at the top every time they wait for the briquettes to form...... This is more accurate and keeps the hole on each briquette consistent! By the way, it is best to use iron to make the mold for briquettes, which is more durable......"

Seeing that the king accepted his opinion almost immediately, Shi Sheng was naturally overjoyed and overjoyed.

And then, the two of them started a discussion about what you said and what I said.

The remaining blacksmith and Han Shan looked at each other, especially the housekeeper Han Shan, who saw Li Yuanjia writing and painting with a blacksmith with a pen and paper without any scruples......
