For Chen Xu, what he most hopes is to squeeze out tea fruit oil first.

After all, gunpowder and steel are not problems that need to be solved urgently at the moment, but they have to eat rice every day. There are seven things to do: food: food, rice, oil, salt, sauce, vinegar and tea. Now everything else is easy to say, and he can tolerate it, but he can't hold on to this oil anymore. If he eats fishy lard or mutton oil today, he feels that he will be blocked by blood lipids and dies of blood vessels if he is not thirty years old.

This is probably a very important reason why the rich people did not live long in ancient times. Nowadays, Qin Shihuang can only eat meat oil every day, but no matter what fat is refined, eating it for a long time will lead to excessive blood lipids, the better the life is, the more serious it will be. The older you are, the more harmful it will be. Therefore, if Qin Shihuang had tea tree oil to eat, he would probably be able to live for a few more years, changing the diet structure, and a healthy diet is also the key to longevity.

However, when Chen Xu looked at the sacks of tea tree fruits, he started to have a headache again, how could he squeeze out the oil?

Later generations used oil presses. Chen Xu also saw the town's oil presses when he was a child. Although they were not oil presses, they used hydraulic presses. They put the oil cakes made of iron hoops and straw into the hydraulic press and piled them up, and then kept pressing them like jacks. The hydraulic press squeezed the oil cakes tighter and tighter. When the pressure was enough, the oil was squeezed out. However, in the era when even the bellows were not sealed well, it was completely like a fantasy to make a completely sealed hydraulic press.

So after a long time of struggle, I had to go to find carpenter Liu Erwa again.

Because Liu Erwa used tung oil, I think there is still a way to squeeze vegetable oil in this era.

"What's the dry oil pressing in Lidian? Tung oil is sold in the county town. Twenty coin per pound, why bother!" Liu Erwa was designing bellows with several apprentices, and was very busy. He was very surprised when he heard Chen Xu asking about how to squeeze tung oil.

"I don't want tung oil, but I want to squeeze tea tree fruit oil!" Chen Xu explained.

"What is the dryness of tea tree fruit oil?" Liu Erwa was even more puzzled.

"You have grown up recently, right? What are you asking so many things?" Chen Xu stared at him and wanted to kick this old man out of the door.

"Lidian Mo is angry, Erwa is too talkative!" Seeing that Chen Xu seemed angry, Liu Erwa became honest, "I have seen the method of oil pressing in the county oil mill. I used a large wood to dig out a round groove of two feet in diameter in the middle. I pounded the tung tung tung with a stone pestle and put it in the pottery jar to steam it. Then I used a round hoop woven by hemp and bamboo skin to make the steamed tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung tung

After Liu Erwa said this, Chen Xu also vaguely remembered that wooden pressing is an extremely ancient method of oil pressing, but it is not too old. I remember that some ancient pressing workshops in remote areas were still used on TV, but they are retained as an intangible cultural heritage just like hand-woven cloth. They are of no use and are not hygienic. When making oil cakes, the old men all step on their feet with their bare hands. What if they have athlete's foot? Even snot, sweat, and some things that cannot be described are mixed together.

But no matter what, now that tea tree fruit is available and oil is also available, Chen Xu decided to squeeze out the oil no matter what.

Big trees are not a problem, and production is not a problem, because I am the Lidian of Qinghe Town. More than 3,000 people in Qinghe Town are the objects that they can exploit and exploit. As long as he is willing, the whole town will use his hands to squeeze out the oil. This is why everyone wants to be the exploiting class, because it is so exciting.

"Liu Po, arrange someone to cut down the big tree on the hillside!" Chen Xu found Liu Po, pointed to the huge chestnut tree on the hill behind the pottery making workshop and said.

Liu Po ​​looked at the big chestnut tree with a diameter of six feet and a height of tens of feet. He was stunned for a long time before he stammeringly asked: "Lidian, it...has it angry?"

"Well, I don't like it!" Chen Xu nodded.

"Can... can you change to a smaller one?" Liu Po's face was twisted like a bitter gourd.

"No!" Chen Xu said firmly.

Liu Po ​​had no choice but to surrender to Chen Xu's power and go to find the tall and strong people in the town to cut down the big wood.

It would probably take two or three days for such a large tree to be cut down, and it would have to be cut off and transported down the mountain, and it would have to be broken into the trough. When it was thought that if a tree with a diameter of more than one meter was broken into the middle, an axe would definitely not work, and a hand saw would definitely not work. It would be necessary to have a double saw at least two meters long, so Chen Xu turned around and looked for the pole.

In order to eat vegetable oil, Chen Xu definitely took the initiative, even if he stopped all the work tasks in the town.

"One...a one-meter-long copper saw?" The blacksmith shop's hemp rod was directing two apprentices to carry loess to prepare a steel furnace base. After Chen Xu said that, he almost fell to the ground after his hind legs were weak.

"No, it must be at least nine feet long, otherwise the big wood would not be sawed out!" Chen Xu said little.

"But even if I can cast such a long saw, how can I use it because it is too long?" Magen finally calmed down his emotions and asked.

"This is an improved double saw, which looks like this..." Chen Xu picked up a wooden stick and quickly drew a common woodworking saw on the ground. "See, you just need to cast a saw blade that is nearly a foot long, make it stronger at both ends. At that time, use a support wood and a wooden bow to fix the saw blade at both ends, and then use a hemp rope and a twister behind the wooden bow to tighten the saw blade..."

After Chen Xu's explanation, Ma Gan also roughly understood the principle of this big saw, so he nodded and said, "Lidian, I try to cast the saw blade, but I don't have much confidence in whether it can be used!"

"Don't worry, it's definitely usable. The saw blade can be wider and increases the strength, but not too thick, otherwise it may not be pulled!" Chen Xu reminded.

"Don't worry, I will try to make it thinner!" Ma Gan agreed, and then directed his apprentice to start making fire for the stove, preparing to start casting this unprecedented super large saw of the Qin Dynasty.

Feeling that everything was ordered, Chen Xu returned to the sugar and wine workshop again, asked Lu Gen to retrieve all the helpers in the workshop, and began to clean up the tea tree fruits, pick out the moldy and shriveled ones, and then pick the remaining ones in the mill and crush them all with a stone mill. The dozens of sacks of tea tree fruits are more than 3,000 kilograms, and it will probably take several days to finish them all.

Therefore, Chen Xu went to the grain warehouse to take a closer look at the remaining trucks of groceries that were unloaded. Most of them were some ores with crystal structures, and the colors were also various. These were metal compounds that Chen Xu thought he could study carefully. What made him happiest was that Zhao Qing did live up to expectations this time and brought him a large jar of sulfur, which was more than ten kilograms, which made Chen Xu very excited.

Finally, Chen Xu opened a bag of Guanyin soil that he had gotten back from the Shui family again, thought for a while, and then got some to the pottery workshop.

"Lidian, what else do you have?" Gao He, who was directing the helpers and apprentices to make tiles, quickly came up.

"Help me make some bowls and cups of this white soil and mud!" Chen Xu took more than ten kilograms of Guanyin soil from the horse's back and said to Gao He.

"Hey, such a delicate white clay?" Gao He was extremely surprised after opening it.

"Haha, this is not ordinary clay. This is called porcelain clay. The objects made are much more beautiful than ordinary pottery. However, to achieve the best effect, the temperature and heat of the fire in the kiln must be increased by nearly twice!"

"How can I burn it? It's useless to add firewood in this kiln temperature!" Gao He said in surprise.

"Don't worry, this time you are guaranteed to get extremely high fire temperatures. However, you can't use a large kiln, you can only use a small kiln. You can use this soil to make some cups and bowls of varying sizes first, try to make it thinner, don't be as thick as usual, just about half of it, build a small kiln next to the large kiln, and just put more than ten pieces in..."

Chen Xu said Gao He and nodded. He admired Chen Xu in a deep mood. Not to mention anything else, just the two things like the flask and the kang completely solved his most troublesome things from work to life.

At this point, after most of the busy day, all the things shipped back this time have basically been processed. The only thing left is to wait, wait until the wool is spinned into wool, wait until the steelmaking furnace is repaired, wait until the oil press is completed, and wait until the small earth kiln for the porcelain is repaired, the remaining things can slowly carry out the next step of experiments and research.
