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 in chaos, 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 your 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 tools together to extract oil."
First crush the pockmarked seeds, use tools to pack them and press them, and wait until the pockmarked oil flows out.
This is cold pressing. Lin Yan feels that the efficiency is very low. It is better to use the hot method, crush the pockmarks and make them into cakes, steam them over fire, and the pockmark 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 ones are that it can be used for cooking, making oil lamps, etc."
It was because she ignored this problem before that she piled up too many pockmarks and wasted a lot. In fact, after you can do carpentry, it is not difficult to squeeze oil, but you 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, and if it can be done, the efficiency will be at least twice as high as before. The same person could weave one piece of cloth for more than ten days using the previous generation loom, but with the new loom, he could weave at least two pieces of cloth in the same time. This 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, "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, there 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. He can't see his original appearance anymore. He looks more energetic like this, like a wild boy." Ye Cong laughed.
"Looking for a 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 here."
"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 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've 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 person's wound and increased the dosage of 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 found it 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 it 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 I don't know when I can finish it. She couldn't pick out the key points and copy them, as it felt like any missing page was wrong.
After almost ten days, Shi Zhi and Lin Cong made 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 hemp 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 meat I made before. Is it almost ready? I want to taste it."
"It will be out of the pot soon." Lin Yan turned the meat in the pot and it smelled better. The aroma of chopped green onion is stronger, maybe because there is enough oil.
When the fried meat was in his mouth, Ye Cong chewed it slowly 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. It's not sticky like the grease we use now."
Lin Yan also felt the same way. With pockmark oil, so many pockmarks could be put to use. "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.
