Chapter 103 Oil Extraction

Asking Huahong to take care of the wheat field while harvesting the roe, Lin Yan went to the laboratory.

Shi Zhi and Ye Cong were discussing something together. The room was very messy, with wood, sawdust, nails, etc. everywhere.

"What are you doing?" Lin Yan looked at the clean place on the ground and stepped on a pile of sawdust.

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

When Shi Zhi heard the voice, he quickly raised his head and said, "You're here, come and see our new design."

"Don't worry, I have something to do with you, so I'll put my work aside and do it later."

Ye Cong and Shi Zhi obediently followed their instructions. Lin Yan now came to them for everything, and it must be urgent.

Lin Yan said directly: "There are too many pockmarks in the city. They are piled up and spoiled. I want you to make some tools together to extract oil."

First crush the pockmarked seeds, use a tool to press them, and wait until the pockmarked oil flows out.

This is a cold pressing method. Lin Yan feels that the efficiency is very low. It is better to use the hot method, crush the hemp seeds into cake balls, steam them over fire, and the hemp seed oil will flow out faster.

After hearing her explain the process, Shi Zhidao said: "It doesn't look difficult to do. The tools are simple and easy to make. Let's give it a try first."

"Okay, I'll leave this to you. Squeeze out the oil, and the pockmarks will have a place to go. The oil can also be used for many purposes. The most important thing is that it can be used for cooking, making oil lamps, etc."

She had ignored this problem before, which resulted in excessive piles of pockmarks and a lot of waste. In fact, after being able to do carpentry, it is not difficult to squeeze oil, but she just didn't think of doing it.

After talking about oil extraction, Lin Yan took a look at their newly designed loom and made improvements based on the original ones according to the drawings she gave.

Threading leads has sped up a lot. If it can be made, the efficiency will be at least double that of before. The same person would need more than ten days to weave a piece of cloth using the previous generation loom. With the new loom, he can at least weave one piece of cloth in the same time.

Taking two steps forward is already a huge improvement.

This is exactly what Hong Ling wants, which can greatly reduce costs and bring down the price of linen.

Lin Yan looked at them with admiration and said, "Do a good job. You are so smart and have strong hands-on skills. 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, apply what you learn. When you do it, you find that many things are connected."

"That's it. Every new thing we make can make life more convenient and faster." Ye Cong also likes this, "Lin Yan, how are your wheat crops going?"

"It's pretty good. We won't know the result until this season matures. However, looking at the current trend, it should be no problem."

Looking at the lean Lin Yan, Shi Zhi joked: "If it's not good, I'm sorry for the sun you get up early every day and get too late."

"Hehe, it's really like this. Lin Yan has changed into a different person, and he can no longer look like his original self. He looks more energetic like this, like a wild boy." Ye Cong laughed.

"Let's fight, who is the wild boy?" Lin Yan was unconvinced, "I am a girl, and I am much more valuable than the wild boy."

"Yes, yes, you are the most valuable." Shi Zhi smiled.

Several people were chatting and laughing, and Huang Ying walked in.

"When I heard your voice, I thought I heard it wrong. Come over and take a look. You are indeed here."

Shi Zhi joked, "Lin Yan is growing in the ground now. It's too difficult for her to come over."

"Exactly, she used to spend time in the laboratory every day." Huang Ying answered, "Seeing that you are happy, it means there is something good going on."

"The loom has made new progress, which is worth being happy about." Lin Yan looked at Huang Ying with a smile, "You came here to ask for something?"

Huang Ying has been obsessed with the study of herbal medicines since last year. She is either experimenting or looking for various herbal medicines. She rarely sees her.

"Yeah, it's rare that I meet you, so I just have something to ask. I found that the dosage of herbs has a great impact on the healing of wounds. Some herbs can be counterproductive if used too much. I want to ask you why this is?"

Huang Ying initially thought that increasing the dosage of herbal medicine would speed up wound healing, but later discovered that this was not the case. She once treated an injured patient's wound and increased the dosage of herbal medicine, but the result was that the wound worsened.

From that time on, Huang Ying fell into confusion. After observing for many days, she still couldn't figure it out.

She compiled the information about each herbal medicine she got from Lin Yan, but she still couldn't figure it out.

Lin Yan was stunned. She felt that this was a very profound question and it was difficult to answer. After reading books about herbal medicine, she felt that it was very mysterious and completely different from the treatment she understood.

"I don't know either."

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

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

Lin Yan wanted to copy the basic introduction to herbal medicine and give it to Huang Ying. Researching medicine is also an important direction. Since Huang Ying is interested, let her figure it out on her own.

It's just that the book is too thick, and she doesn't know when she can finish copying it. She can't pick out the key points to copy, and it feels like any missing page is wrong.

After almost ten days, Shi Zhi and Lin Cong finished the oil extraction tools. After testing, they could squeeze out oil.

After Lin Yan looked at it, he felt that the squeezed oil was a bit turbid, so he added a filter and used several layers of burlap to act as a filter.

"It looks much better this way. Can this sesame oil really be used for cooking? Why don't we give it a try first?" Ye Cong was eager to try.

Shi Zhi also said: "There is a pot in Lin Yun's house. I will go find some fresh meat. Let's fry the meat and see how it goes."

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

In fact, there is no problem in eating pockmarked oil. In the past, the pockmarked seeds were shelled and crushed into pockmarked paste. There was also a layer of oil inside, and people had already eaten it.

But they still feel uneasy and want to verify it for themselves, so just do it again.

When the aroma of meat wafted 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 in agreement, "It feels more fragrant than the fried pork I made before. Is it almost ready? I want to have a taste."

"It will be out of the pot soon." Lin Yan turned the meat in the pot, and it smelled more fragrant. The aroma of chopped green onions was stronger, maybe because there was enough oil.

When the fried meat was in his mouth, Ye Cong chewed it carefully and said, "It tastes better than before and not so greasy. From now on, I will fry the meat with hemp oil."

Shi Zhi swallowed the meat in his mouth and nodded, "Yeah, I think so too. The pockmark oil looks clear and doesn't clump together, unlike the grease we use now, which is sticky."

Lin Yan also thinks so. With pockmark oil, so many pockmarks can be put to use. "It's successful. Now we want to build an oil pressing workshop. Do you two have anyone to recommend?"

The technology belongs to both of them, and Lin Yan doesn't want to interfere too much.
