Although I have never been in contact with the oil pressing industry, and even more so, as an engineering student, my understanding of the principles of machinery is a basic skill. Through observation of wood presses and the structure of the oil press found in the library, I have a full understanding of the structure of the oil press, and naturally I also know what kind of oil press should be designed.

First, the oil press must use hydraulic power.

Hydraulic power is the best choice for reducing manpower, at least in this era.

Adhering to this principle, after repeated conception for a long time, Shi Yiwen spread the paper on the table, and then took a pencil and a measuring ruler and other tools to draw the design drawings of each component of the oil press. However, after only half an hour, almost half of the drawings had been completed.

Kou Yun, who entered the study with a fruit plate, asked in confusion when he saw the young master drawing something.

"Young Master, what are you painting?"

"This is a new type of oil press, which is labor-saving and more oil than using wood to press oil now."

Kou Yun said in surprise.

"Young master, our family is going to run an oil mill? That's not a clean job."

In Kou Yun's opinion, the oil mill is all done by hardworking, so she was surprised.

Shi Yiwen smiled and did not answer her question, but took the drawings to the blacksmith shop to find someone to make the oil press.

When he went to the blacksmith shop, Shi Yiwen didn't even care about it and handed over the drawing parts to the blacksmith. He was not worried that the blacksmith knew the structure of the oil press, because even if it was copied, it would be useless. Now it was just a big iron lump.

In the blacksmith shop, Feng Jiangtou looked at the drawings, looked left and right and didn't understand.

"Young Master wants to cast iron frames like this with iron? What is this for?"

The so-called oil press is very simple, but it is actually a cast iron frame with a pressing tray. This is why Shi Yiwen does not keep it confidential at all. The structure is too simple, and the iron lumps cast in one-time are cast.

"Can it be cast?"

Shi Yiwen did not answer Feng Jiangtou's words, but asked directly.

"It's all made of iron, at least five or six hundred kilograms. Can it be cast at one time?"

"Look at what you said, young master, our Feng Ji Tiefang, but even a 3,000-pound iron bell was cast, five or six hundred pounds, a piece of cake. When do you want this thing?"

“The faster the better!”

Although Shi Yiwen rarely cares about the factory after the factory got on track, the raw materials have now affected the production in the factory and naturally cannot be delayed.

"Five days, five days later, I'll definitely send this to you."

After leaving the blacksmith shop, Shi Yiwen did not waste time, but instead went to the oil mill and began to renovate the oil mill. Although the oil mill originally had a water wheel, the old water wheel was too efficient, and a new water wheel needed to be built. A new transmission system was also needed to be redesigned. By using belt transmission, the power became controllable.

In fact, this belt transmission system did not take much time. After all, there were similar transmission systems in history, namely the so-called sky shaft or ground shaft. It was installed above the factory or on the ground and driven by a power machine. They were once widely used to drive machine tools and other equipment. Later, as the working machines were driven by separate motors, they were eliminated.

This set of equipment seems complex, but it is actually very simple. It can further simplify the structure when used in hydraulic power. For those skilled carpenters, there is no trouble to use hardwood to make this wooden transmission system.

The real problem is probably the raw material for oil pressing.

"...The oils used for eating are mostly veal, cabbage, sushi, and hemp seeds. As for soybeans, because steaming the ingredients takes time and the grains are too hard, they are not used much."

Standing in front of the new owner, Sun Jiaqin seemed very cautious. In the past, this oil mill was from the same clan uncle and had some family affection, but now the owner has nothing to do with him. He was left behind because the owner needed someone to manage the oil mill. Whether he could get the owner to appreciate it depends on his ability in the future. However, Sun Jiaqin was extremely arrogant about this. After all, he had been working in the oil mill for thirty years and knew everything about the oil mill.

"There is the oil used for lighting lamps. For example, water oil in cypress kernels is the best, flax seeds are followed by cotton seeds. However, because the water oil price of cypress kernels is high, flax seeds are foul-stenched and produced in Shaanxi, so cotton seeds are mostly used in Jiangnan..."

Listening to Sun Jiaqin's introduction, Shi Yiwen asked directly.

"Who is the cheapest here? I mean the raw materials."

Since it is to make soap, you naturally need to use the cheapest raw materials.

"When I go back to my home, the raw materials for oil pressing have their own prices, and the prices vary. However, generally speaking, our oil mill is dominated by rapeseed, and the prices of this rapeseed..."

Before he finished speaking, Sun Jiaqin, who was good at observing his face, noticed that his boss seemed to have no interest in Caizi, and quickly replied.

"If you eat edible oil, the cabbage is the cheapest. People grow more, and the seeds are crispy and oily. Therefore, ordinary people often focus on cabbage, and sesame oil, which is slightly more delicious, but the taste is good. If it is lamp oil, it is cotton seed oil the cheapest. In fact, it is the cheapest in the squeezed oil."

"Cottonseed oil is the cheapest? What is the cheapest way?"

Shi Yiwen said in surprise.

"The boss, I don't know anything."

Looking at his boss who looks like a rich young man, Sun Jiaqin only thought he didn't understand the market.

"In this world, cotton is grown to spin and make quilts. Naturally, no one wants cotton seeds. But this thing is too large. There must be at least 60 kilograms of cotton seeds in a hundred kilograms of cotton. This thing is useless at all. Even if you feed livestock, you don't eat them. At most, you can only use them to ferment fertilizer. It's useless. It's naturally worthless. Although people have always used it to squeeze oil, the oil quality of the cotton seeds is not so good, and the oil is also time-consuming and labor-intensive. It produces very little oil. If it weren't for the oil residue after the cotton seeds were squeezed oil, and the cotton seeds were not worth a penny, probably no one would use it to squeeze oil and use it to light the lamp."

Cotton seeds are useless?

Difficult to squeeze?

With an oil press, what oil cannot be squeezed?

Sun Jiaqin's words surprised Shi Yiwen.

“What is the price of cotton seeds.”

"The owner, cotton seeds are not worth anything at all. After the cotton merchants rolled out the cotton, many cotton seeds would be piled up in the yard. Those cotton seeds were useless at all and they would take up space there. So the oil mill was responsible for pulling away the cotton seeds without paying money to buy them. As long as they were shipped away, the oil mill used cotton seed oil to the people as lamp oil. As for the oil mill, the oil slags would be sold to the people around the city. They would either feed the livestock or feed the mulberry trees. Only in this way can they barely cover the capital. If they pay to buy it, it would definitely not be enough."

Well!

There is also such an operation!

With his eyes wide open in shock, Shi Yiwen stared at Sun Jiaqin and asked.
Chapter completed!
