Stir-fry the beans dry and stop when the skin becomes a little oily.

Then use a stone mill to grind the fried beans into fine particles, which is a hard work, and it takes a relatively strong person to work hard to grind the beans into fine particles one by one.

This process is not difficult, but it is a bit costly, but the current level of science and technology can only be like this.

Then the fine particles are wrapped up in a cloth, which is also the most stupid method, a stone is punched out of a stone groove that can leak oil, a cloth containing soybean particles is placed on it, and a large and heavy stone is pressed.

Under the pressure of the stone, the grease in these particles will be squeezed out.

The salary of 40 copper plates a day is not easy to find in other places, so these recruited people work very hard, Xue Rou asked them to find big and heavy stones, which are really big and heavy, and the two stones are as high as thighs.

"Is that okay?" Lu Yi, who likes to soak in the begonia tree and read, was also alarmed and looked curiously.

Xue Rou nodded, looking at the soybean grains between the two stones expectantly, don't look at a small bean, the oil yield can be more, as high as 20%, once discovered, it will quickly replace other plants that can produce oil, but the oil yield is not high.

That is, Da Zhou's side has not thought of this, and uses those expensive plants to make oil every day, and the price is too expensive to die. But maybe one smart guy will try it, and then this one, alas, soybean oil will be produced.

Of course, with her presence, this clever guy may not have this chance, and she decides to do her best to try to reduce the price of oil to a third!

The oil yield of soybeans is 20%, ten catties of beans, two catties of oil, soybeans are very cheap, two copper plates for a catty, ten catties is twenty copper plates, that is to say, ten copper soybeans can produce a pound of oil, add some labor costs, patent fees, she sells thirty copper plates, not too much, right?

The current oil price is ninety copper plates a catty, Xue Rou believes that when she succeeds in oil extraction, it will be the time of a sensation in the county!

Then as long as you sit on the bench, you will have a steady stream of money coming to you!

This is not counting the remaining bean dregs, the value created by the bean cake can be used to feed the pigs!

"Tick!"

"Out of ...... It's oily! ”

The first drops of oil slowly gathered from the stone trough, and when they dripped down, the whole farm screamed excitedly.

The women who had participated in the labor were even more excited, beating their chests like orangutans, and their mouths were screaming, like humanoid Taishan.

Although they still don't know the terrible oil yield of soybeans, they know that soybeans have two copper plates and a pound.

And other plants, those yellow mustard seeds all need three, or even four copper plates a catty, and they are all in the hands of those oil mill people, this is the first time they have seen the process of oil extraction, how can they not be excited?

This process was undoubtedly slow, and after Xue Rou witnessed the production of oil, she did not continue to guard it. Not only did he not keep it, but he also wanted to give everyone else a vacation, but these hired people shook their heads one by one and refused.

A sturdy female man widened her eyes even more, and her face was full of disbelief, "Dongjia, how can such a good oil be left unguarded?" ”

"Boss, if you feel tired, go back first, we can help you guard it for free."

Xue Rou: ...... For the first time, I saw employees who took the initiative to help with work and did not need money.

Why are they more active than her owner?

Of course, these people are active, when they usually earn money, they have to work like an old ox all day long, how can they have the opportunity to stop and rest, but this afternoon, they just worked casually for a while and finished it, and they still got such an expensive salary, and their conscience was uneasy!

Although they will be busy in the future, they may be more tired, but they are willing, 40 copper plates a day! Before, they were moving goods at the dock, and there were only more than 20 copper plates a day.

As for those husbands who are idle at home every day, even if they do a lot of work at home, they are so tired that they can't see a copper plate a day.

So this high-paying job, they are more attentive than those women who work on the docks every day.

As long as this oil-making thing does not leak for a day, they can get an extra salary of 40 copper plates a day, can they not care?

That night, several husbands and all the people in charge of the family agreed to take turns to come on duty, guarding the place where the oil was pressed, and they couldn't sleep, and their eyes were reluctant to blink.

Similarly, if it weren't for Lu Yi's identity as an unmarried brother, he would have stayed at the farm and witnessed the final results.

Bowls of oil were squeezed out, smelling the unique fragrance of soybean oil, the expressions of the people guarding the side were uncontrollable, and their eyes looked in the direction of the grocery store.

Yes, Xue Rou's identity as a person praised by His Majesty In just one day, almost everyone knew that the people here had no entertainment facilities, and they all relied on gossip.

Therefore, even if they rely on their mouths to spread gossip, they are still very fast? It's even faster than in the era of big data.

At this time, Xue Rou was learning sow maintenance knowledge in the house, not books, but videos that had been downloaded in the mobile phone in advance, in order to prevent the mobile phone from running out of power, she also brought several tens of thousands of milliamperes of power banks.

After studying for an hour, that is, two hours, Xue Rou still couldn't sleep, maybe there were too many things happening today, right?

I couldn't help but pick up the pen, she had to record these things well, and it would definitely look like it would be more enjoyable in the future.

Early the next morning, Xue Rou began to inquire everywhere where there were little piglets to buy.

Pork is fishy, most people don't eat it, only those who are poorer at home will buy some to add oil and water, so selling pork is not actually very profitable, just making hard money.

So when Xue Rou inquired about the boss who sold pork, the boss only hesitated a little and happily reported the place.

"Pork is cheap, so people rarely raise pigs, if you want to raise pigs, you can go to that Linshui village to inquire, Linshui Village Lao Xu, our pork is bought there."

They are old shops that have been in business for many years, and they are not afraid that others will rob them of business, and this business is not oily and water, and the biggest customer is Xue Rou's daily indispensable lard order, how could they offend this big master because of this?
