"Did they say anything else?"

Yi Niang nodded and continued: "They said that our charcoal looks like a big piece, but it is not burned thoroughly enough. It has turned into ashes on the outside and has not turned into charcoal on the inside."

"Did they explain why this happened?"

Liang Chuan's charcoal-burning skills are only half-baked. He usually builds a mound of earth and burns hundreds of kilograms of charcoal, and sells it to a few inns. However, this won't work if he encounters experts.

"They just said directly that our charcoal was fired in an earthen kiln. The kiln is not good enough, so the quality of the charcoal cannot keep up."

Liang Chuan chuckled, he is indeed an expert. What kind of kiln is this? It is just a broken charcoal kiln made by myself. It was made by imagining the old charcoal kiln in his hometown based on his feelings. It must be in the eyes of experts.

Not worth mentioning.

Yi Niang trotted into the room and returned quickly, then handed Liang Chuan a drawing. Liang Chuan spread the paper and saw that it turned out to be the construction drawing of the charcoal kiln.

Liang Chuan simply couldn't believe his eyes. Regardless of whether the drawing was genuine or not, or where the two people came from, they gave up the charcoal kiln drawing so generously. You must know that in a certain sense, this thing is

It is equivalent to a trade secret. If too many people know about it, it will definitely be difficult for them to do business.

Could it be that they have mastered this technology and are not just selling charcoal, and they want to use it to defeat their opponents? It doesn't seem like it. They claim to be businessmen from Guanzhong. This is Xinghua, and the two places are thousands of miles apart.

, we won’t be able to influence each other when doing business.

"They left this drawing, did they say anything else?"

"Yes, they said that we have many forests in the south, and there are tree species that can be used to make charcoal everywhere. If we have more charcoal in the future, we can transport it to the north to sell. They are specialized in the charcoal business, and they are willing to harvest any charcoal they have.

!”

This is it. No wonder these people drew the drawings so simply. They turned out to be charcoal dealers. What they do is to collect charcoal from the charcoal harvest at a low price, and then sell it to those who need it at a high price.

As a trading company, you don’t have to do anything. You can complete a profitable business by relying on the channels in your hands.

They are not afraid that their charcoal-making skills will be exposed, but they hope that others will continue to sell them charcoal, so that their financial opportunities will be wider.

Bai Juyi's "The Charcoal Seller" said it well: What is the purpose of making money from selling charcoal? The clothes on your body are what you eat. The charcoal sold by a charcoal farmer is only enough to buy a suit of clothes and a mouthful of food. Why are the tree resources in the south so poor?

There are many, but there are very few people doing this business. Is it because they don’t know the technology of burning charcoal? No, it’s because they don’t have sales channels.

If charcoal is used and controlled well, it can even influence the policy direction of the imperial court. At this time, most people in Bianjing City burned firewood and charcoal in the winter. Coal was not widely used in this era.

Only in coal-producing areas such as northern Shaanxi and Shanxi can it be convenient for ordinary people to obtain it, and it will naturally be easy to promote it.

If a small charcoal forms a monopoly, it can form an energy status equivalent to three barrels of oil!

If you carry charcoal of the same quality in a bamboo basket and sell it on the street, the target customers may only be farmers and women on the street. Even if they can afford the charcoal, the price is extremely low. But once you have sales channels, such as

Commercial banks or restaurants, or large households in Suzhou and Hangzhou in Tokyo, need extremely large amounts of charcoal, the demand is very stable, and the purchase price has enough room for profit, so that they can make a profit.

Even in the twelfth lunar month, the climate in the south is still over ten degrees Celsius. Except for a few days when the extreme cold wave comes, it is barely below zero. Otherwise, the temperature is not too cold. Who in the small farmers would be so delicate and want to light charcoal to survive the winter? Go to the mountains and live alone

Just pick up some scraps of firewood and you can have a strong fire!

So there is no business in making charcoal in Fengshan. The reason why Liang Chuan wants to make this industry big now is because he has Wanda on hand. Wanda can be used as a department store or a chamber of commerce in the future, and charcoal can be placed here to sell retail and bulk goods.

In the future, we can rely on sea ships or canals to send them to Suzhou and Hangzhou, and then to Bianjing.

As far as Liang Chuan knows, the amount of coal required by Bianjing is an extremely huge amount every winter. The supply of coal from the entire surrounding area to Bianjing is still in short supply. As long as he can open this road, a money printing machine will be needed.

Even if it is caused, what is transported north is charcoal, and what is transported back is money.

It’s just that this plan is not easy to implement. It takes thousands of miles to travel to Bianjing. Although the quality of charcoal is not heavy, it is large in size and is extremely inconvenient to transport! The result is that transportation costs compress profits. Unless there are convenient transportation channels, it will be difficult to make charcoal.

Continue!

You can’t sell it, but you can still make it by using it yourself! Even if it is sold to restaurants in Fengshan and Xinghua City, the charcoal they need is still a huge amount, and they will make a lot of profits a year. Those orphans in Chihe have nothing to do.

, just right for them to run this business!

Liang Chuan picked up the drawing. It not only had pictures on it, but also various sizes and construction points. Under the drawings, there were text introductions and instructions. It was a combination of pictures and texts. This was really not about hiding something, but about giving away money.

Teach each other.

Liang Chuan even sighed in his heart, wishing he had met these two noble men earlier, he would have saved himself from building a useless kiln, which burned poor charcoal and was time-consuming and labor-intensive.

The drawing states that the site of the charcoal kiln should be located north to south, which is completely opposite to the design concept of Liangchuan Nakong kiln. Liangchuan is backed by a mountain, and the wind is completely blocked by the mountain. This new type of charcoal kiln is

It uses north wind ventilation to make the fire burn more vigorously, so as to improve the combustion efficiency.

The charcoal kiln is divided into three main bodies, a round hole-shaped burning mouth, a cylindrical charcoal baking chamber, and a chimney. Looking at the scale of this charcoal type, one kiln can burn about a thousand kilograms of charcoal at least.

.It is even noted below that the conversion ratio of this kind of charcoal kiln is one to five to seven, which means that five to seven pounds of charcoal can produce about one pound of charcoal.

You must know that the conversion ratio of Liang Chuan's muddy earth charcoal kiln at the beginning was only one to ten, that is, it takes one hundred kilograms of wood to burn ten kilograms of charcoal. This kiln is not difficult to produce charcoal up to one thousand kilograms, and

It can save nearly 30% to 50% of the wood.

According to this charcoal-burning method, only about ten kilns can be burned on a hilltop, and the available tree species on the mountain are almost exhausted. At that time, the charcoal kiln will have to be moved to other hills, otherwise one kilogram of charcoal will cost five to seven thousand kilns.

How about moving a kilogram of wood with just manpower without vomiting blood?

"They gave you the drawings. Did I tell you the techniques for burning charcoal?"

"Yes." Yi Niang smiled sweetly and said, "Master Baozheng was next to me at the time. Seeing that I was talking so passionately to them, he was afraid that I would be deceived by them, so he kept pulling me."

Liang Chuan nodded and said: "It is essential to be on guard against others, and it is also good to be more cautious."

"They say that lighting a fire and burning charcoal requires skills. Before lighting a fire, put two finger-thick wooden branches on the chimney mouth to observe the degree of charcoal baking. When lighting a fire, use dry wood to ignite the fire. After the fire power increases and the kiln body is heated, use wet wood.

The wood is burned slowly over a low fire so that the kiln body of the charcoal baking chamber is slowly dried and the wet charcoal wood is slowly baked. At this time, black smoke comes out of the chimney."

Yi Niang paused and continued: "It will take a day to continue burning like this, and then add more firepower until green smoke comes out of the chimney, and observe that the wood branches on the chimney mouth have been charred, which means that all the wood in the charcoal baking room has been burned.

Carbonization, at this time, use earth to seal the burner port and chimney."

The sealing effect is the same as how we seal the top of the earthen kiln, the burner port and the ventilation hole. It allows the charcoal to react without oxygen in the charcoal kiln. However, the kiln wood only weighs a hundred kilograms at a time. This new type of one-kiln

If there are several kilograms of wood, the sealing and cooling time must be much longer than that of an earthen kiln.

"Five to seven days after the kiln is closed, the sealed fire opening, charcoal baking chamber opening and chimney can be opened to facilitate ventilation and cooling of the charcoal kiln. This is considered done. I remember what the two businessmen told me at the time.

You must have heard it correctly."

Liang Chuan listened patiently, and based on the drawings in his hand, he believed that the two businessmen did not lie to Yi Niang. It was indeed an extremely high craftsmanship for making charcoal. Although it could not be compared with the machine processing of later generations, in the manual era

, this has been accumulated over thousands of years of experience.

"Yi Niang, this method seems to be better than ours, so from now on you will be mainly responsible for burning charcoal. But I am worried about these children."

"What happened to them?"

Yi Niang's eyes widened, and she was more nervous than anyone else when talking about these children.

"This kiln requires several kilograms of wood. If you just rely on these children... can their bodies handle it?"

Yi Niang pondered for a moment and said: "If a dozen children have to cut several thousand kilograms of wood a day, it is indeed a bit much, but it does not have to be so much every day, and by then I will make some tools such as iron saws, so that

They cooperated and did not strive to finish the work in one day. It does take five to seven days. We can prepare the wood during this time. In this way, the work in one day is not particularly large and it is not too tiring."

"Well, since they choose their own path, you have to take care of them. They are growing up now, so they should work in moderation. If they are too tired, they may not grow taller. You have to pay attention.

"

Yi Niang spat at him, curled her lips and said: "I don't want to exploit them. If they don't want to do it but choose to come to the academy to study, then I would be even happier. It sounds like I am a vicious woman."

"That's not what I meant. It's just that there are some things you don't know. Accidental collisions will affect the physical growth of children."
