Let Hua Hong take care of the wheat field when she was harvesting the thorn, and Lin Yan went to the laboratory.

Shi Zhi and Ye Cong were discussing something together, and the house was very chaotic, with wood, sawdust, nails, etc. everywhere.

"What is this doing?" Lin Yan saw that there was no clean place on the ground, and stepped on a pile of wood chips.

"Make a spinning device." Ye Cong didn't raise his head, holding a nail in his hand, ready to nail two pieces of wood together.

Shi Zhi hurriedly looked up when he heard the voice, "You're here, come and see our new design." ”

"Don't worry, I have something to do with you, put the work in hand first, and then do it later."

Ye Cong and Shi Zhi obediently did so, Lin Yan now has nothing to do but look for them, and it must be a matter of urgency.

Lin Yan said directly: "There are too many hemp seeds in the city, and they are all piled up and damaged, I want you to make some tools together to extract oil." ”

Crush the hemp seeds first, pack them with tools and press them, and wait for the hemp seed oil to flow out.

This is a cold pressing, Lin Yan feels that the efficiency is very low, it is better to use the heat method, crush the pockmarks into cakes, and steam them on the fire, and the hemp seed oil will flow out faster.

After listening to her finish the process, Shi Zhi said: "It's not difficult to do, the tools are simple and easy to make, let's try it first." ”

"Okay, then I'll leave that to you. When the oil is squeezed out, the hemp seeds have a place to go, and the oil has many uses. The main thing is to be able to stir-fry, make oil lamps, etc. ”

It was she who ignored this problem before, so she let the pockmarks pile up too much and waste a lot. In fact, after being able to do carpentry, it is not difficult to extract oil, but I just didn't think to do it.

After talking about oil extraction, Lin Yan looked at their newly designed loom, and made improvements on the original basis according to the drawings she gave.

The threading lead has been accelerated a lot, and if it is made, the efficiency is at least twice as high as before. The same person, using the previous generation of looms to weave a piece of cloth in ten days, replaced by a new loom, the same time can make at least two steps, this is already a huge progress.

It is exactly what Hongling wants, which can greatly reduce the cost and reduce the price of linen.

Lin Yan looked at them appreciatively, "Do a good job, you are too smart, and your hands-on ability is also strong, it won't take long to make it." ”

Shi Zhi indulged in it every day, and said happily: "It's so interesting to do this, just like you said to apply what you have learned, and when you do it, you realize that many things are connected." ”

"That's it, every new thing that comes out makes life easier and faster." Ye Cong also likes to be like this now, "Lin Yan, how is your wheat grown?" ”

"It's good, we'll know the outcome when the season matures. However, looking at the current trend, it should be no problem. ”

Looking at the lean Lin Yan, Shi Zhi teased: "If it's not good, I'm sorry for you getting up early every day to be greedy for the sun and sun." ”

"Hey, that's true. Lin Yan has changed and can't see what he used to be. It looks more energetic like this, like a wild boy. Ye Cong laughed.

"Looking for a fight, who is the wild boy." Lin Yan was not convinced, "I'm a female doll, much more expensive than the wild boy Jin." ”

"Yes, yes, you are the most expensive." Shi Zhi said with a smile.

A few people laughed, and Huang Ying walked in.

"When I heard your voice, I thought I heard it wrong, come and see, you are indeed here."

Shi Zhi laughed, "Lin Yan is growing in the ground now, it's too difficult for her to come here." ”

"Exactly, she used to soak in the laboratory every day." Huang Ying answered, "It's a good thing to see how happy you are." ”

"There is a new development in the loom, which is something to be happy about." Lin Yan looked at Huang Ying with a smile, "Is there something wrong with you?" ”

Huang Ying has been obsessed with the study of herbs since last year, either experimenting or looking for various herbs, and rarely sees her.

"Yes, it's rare to meet you, and I just happened to ask something. I have found that the dosage of herbs has a great impact on the healing of wounds, and some herbs can backfire if used too much. ”

Huang Ying initially thought that an increased amount of herbs would speed up wound healing, but later found out that this was not the case. She once treated a wounded person's wound and increased the amount of medication, only to make the wound worse.

Since then, Huang Ying has been confused, and has been observing for many days, still not having a clue.

She sorted out the information about each herb she had obtained from Lin Yan, but she was still puzzled.

Lin Yan was stunned for a moment, she felt that this was a very profound question, and it was difficult to answer. After flipping through the books on herbal medicine, she felt that it was very mysterious, and it was not at all the same field as the treatment she understood.

"I don't know."

Huang Ying was stunned, "I really don't know?" ”

"I really don't know, when I'm done, I'll find you some books, and you can study it yourself."

Lin Yan wanted to copy out the basic introduction to herbal medicine and give it to Huang Ying. Studying medicine is also an important direction, since Huang Ying is interested, let her figure it out for herself.

It's just that the book is too thick, and I don't know when I'll finish copying it. She couldn't pick and choose the key points from it to copy, and it felt like it wasn't right to miss any page.

After almost ten days, Shi Zhi and Lin Cong made the tools for extracting oil, and after testing, they could squeeze out oil.

After Lin Yan saw it, he felt that the oil squeezed out was a little turbid, so he added a filter, and superimposed several layers of burlap to act as a filter.

"It looks much better like this, can this pockseed oil really stir-fry, should we try it first?" Ye Cong was eager to try.

Shi Zhi also said: "There is a pot in Lin Yun's house, I'll go find some fresh meat, let's fry the meat to see the situation." ”

"Okay, go ahead, I'll take care of it." Lin Yan said with a smile.

In fact, it is no problem to eat hemp seed oil, in the past, the hemp seeds were peeled and crushed into hemp paste, and there was also a layer of oil in it, and people had already eaten it.

But seeing that they are still not at ease, and want to verify it in person, then do it again.

Waiting for the smell of meat to waft out, Shi Zhi and Ye Cong took a deep breath.

"It's so fragrant." Ye Cong looked at the stir-fried meat in the pot and kept swallowing his saliva.

Shi Zhi nodded approvingly, "I feel that the fried meat is more fragrant than the one I made before, is it almost better, I want to taste it." ”

"It's going to be out of the pot right away." Lin Yan turned the meat in the pot, and it smelled even more fragrant. The aroma of chopped green onions is heavier, probably because the oil is well placed.

When the fried meat was eaten, Ye Cong chewed it slowly and said, "It's better than before, not so greasy." In the future, stir-fry the meat with hemp seed oil and eat it. ”

Shi Zhi swallowed the meat in his mouth and nodded, "Mmmm, I think so too." The hemp seed oil looks clear and does not clump, unlike the grease used now, which is slimy. ”

Lin Yan also thinks so, with hemp seed oil, so many hemp seeds will be useful. "It's successful, now you want to build an oil mill, do you two have anyone to recommend?"

The technology is the two of them, and Lin Yan doesn't want to meddle too much.
