Chapter 222 Two Barrels of Oil

After Li Yan discovered tung trees and isatis root at the original site of the Ge tribe, he returned to the Jiang tribe with some samples.

He first ordered people to use Radix Radix to boil water to dye cloth to solve the dye problem, and then ordered the tribe to collect enough materials from the original site of the Ge clan, and to open up wasteland to plant Radix Radix!
After that, he began to study the production of tung oil.

After half a month of hard work, he finally found some clues.

Tung oil is pressed in much the same way as olive oil.

However, this tung oil product can be divided into two types, and the properties and functions of these two tung oil products are different.

Tung oil is mainly squeezed out of tung fruit. For example, if you directly squeeze the tung fruit, you will get a golden and transparent oil. This is raw tung oil. Raw tung oil is relatively thin and not easy to solidify. It can be used for burning or Make oily materials.

But if you fry the tung seeds in the tung fruit and then squeeze them, you will get cooked tung oil. The color of this cooked tung oil is dark brown, very viscous, the oil tastes strong, and it has a strong smell of lacquer. Dries fast, light weight and so on.

At the same time, this cooked tung oil is the most widely used industrial raw material. It is the best waterproof and anti-corrosion material for painting furniture, making wooden boats, and fishing gear.

On the side of the industrial park in the valley, there are two oil mills.

They are "tung oil refinery" and "edible oil refinery", and these two oil factories are also vividly called "two barrels of oil" by Li Yan.

The edible oil refinery was expanded from the original olive oil production line. Now, in addition to olive oil, this edible oil factory also produces peanut oil to meet the needs of the tribe and beyond. Many people have begun to use edible oil in their diet. , The output of this oil plant is also increasing.

A half-carved tree trunk is installed on a wooden wall, and a hole is opened at the other end. A wooden post is inserted into the trunk, like a huge needle barrel, and some oil-extracting materials wrapped in hay are placed inside. The other end hits the wooden pillar, and the oil inside will overflow when it is squeezed. If there is a beast to help, it will save more effort.

This is the new oil extraction machine of the Jiang tribe. Although its appearance is relatively simple, it is much better than the previous ones, and it can also achieve large-scale production.

In the tung oil refinery, there is also this kind of oil extraction machine.

The tung oil factory mainly produces raw tung oil and cooked tung oil, so there are two oil pressing machines here, which are also divided into two workshops.

Some workers sort out the tung seeds, and then send them to the oil press machine to directly press the oil.

As the wooden pillar continued to be hit, a section of the wooden pile would have a golden liquid flow out, and the golden liquid flowed into the ceramic jar from the slanted outlet.

Li Yan stood watching from the side, nodded in satisfaction, and said to others: "The raw tung oil is very good, move it outside for me, and prepare cores at the same time, as well as the pottery that I asked the pottery department to burn a few days ago. I want to see the effect."

"Yes, patriarch."

The clansmen went to make preparations, and while Li Yan still had time, he went to inspect the workshop next door.

The workshop next door is producing cooked tung oil.

I saw that they fried the fresh copper, then sent it to the oil extraction machine, and pressed it hard. After a while, a lot of dark brown thick liquid flowed down from the outlet, and flowed into a small clay pot.

Cooked tung oil dries quickly in contact with air, so it must be stored in a small clay pot.

When Li Yan approached, he smelled a strong smell of paint, which was cooked tung oil.

"Not bad." Li Yan smiled with satisfaction.

"Patriarch, what is the use of oil and water?" The worker next to him couldn't help asking.

"This can be used to make furniture, brushed on the furniture, so that the furniture can last longer, and it can also be painted on wooden walls, wooden boats and other wooden objects." Li Yan replied.

The worker scratched his head, thinking seriously about what Li Yan said.

Li Yan ignored him, and after inspecting the workshop, he went out and came to the yard of the tung oil factory.

At this time, the clansmen had already prepared the materials here according to Li Yan's instructions.

There is freshly squeezed raw tung oil, a few pottery candlesticks, and several types of wicks.

The candlestick is made of pottery, with a concave pottery dish on the top to store oil, and a supporting platform below, which is an ordinary candlestick.

And those wicks have several bells, made of silkworm rope, hemp rope, and some white wicks of plants.

The tribesmen now live the days of working at sunrise and resting at sunset. At night, most of the tribesmen will choose to sleep.

Sometimes when you go to bed late, it will be too late. Many people will start a fire at home, which not only wastes resources, but also fills the room with smoke, which is very inconvenient. Sometimes it is not convenient to go out to pee at night!

Therefore, Li Yan intends to invent oil lamps to solve the problem of night lighting for the tribesmen. Before that, Li Yan used olive oil as oil lamps. However, olive oil is used for food, which is too extravagant. Now, he discovered raw tung oil. Li Yan planned to spread oil lamps to tribal people's homes.

I saw him pour raw tung oil into the lampstand, then put wicks of various materials, and try them one by one.

However, the smoke from burning tung oil is very black, and the smell is a bit pungent.

After experimenting, Li Yan found that the grass wick can be burned well. You know, hemp thread and silk thread are good materials for making linen cloth. Using these two materials as a wick will undoubtedly increase the cost, and this grass wick is not good enough. , but it is cheap enough.

Li Yan was very satisfied with these grass cores, so he asked others: "Where does this grass core come from?"

"Master Hui, this kind of grass core was collected by the river in the south of the tribe. In the past, the tribe used this grass to fill animal skin clothes. You said you were looking for a material similar to silk rope, so I found this grass."

"Well, very good. From now on, this kind of grass will be called rush grass. You arrange some people to go to that river section to manage these rush grass and plant rush grass. This kind of thing is used in large quantities, so it must be planted on a large scale." Li Yan said .

"Yes." The tribe nodded.

Li Yan picked up the pottery candlestick and looked at it, and said all over the place: "This candlestick is made of pottery, it's very good, and there will be another product in the tribal pottery industry in the future."

Then he looked at the others and said, "You potters, make me a thousand of these candlesticks."

The pottery tribe was stunned, and even replied: "Patriarch, there are less than 1000 people in our tribe. Isn't it too much to make a thousand?"

"How's it going? I'll sell it to other tribes later, and I'll keep it in storage for later use." Li Yan said.

"Well, I'll do it now."

Then Li Yan stood up again, and called the directors of the tung oil refinery and the edible oil refinery to come to him.

The two supervisors are both older women. Women in the tribe can read a lot, so many management positions in the tribe can only appoint them, but this is not a problem.

"You two, one is Guan Tung Oil and the other is Guan Edible Oil." Li Yan looked at them.

"That's right, patriarch, our cooking oil is distributed directly to each village, and then the village chief distributes it to the villagers." The cooking oil supervisor replied.

"I don't need to be so troublesome in the future. I plan to build a gas station in Jiangcheng. From now on, the villagers of each village will go directly to the gas station to buy gasoline." Li Yan thinks that private ownership should be implemented now, after all, it is inevitable that some village chiefs will be corrupt.

"Gas station?"

Everyone present was stunned, it was the first time they had heard of this emerging term.

"Patriarch, if those villagers keep going to refuel, wouldn't we be at a big loss? How can this work?" Someone soon discovered the problem.
