"Okay, okay, I'm fine. What about you? "Lessi and Gu Xinyu are also very interesting friends, the two are obviously different personalities, but they can play together, and the relationship is very good.

"You're not afraid to cause trouble for them. If we're going to stay, we'll have to bring some things with us. ”

"Miss Xinyu, it's no problem to care about your meals. Besides, you won't be able to eat much. Tang Wanwan said with a smile.

"See, it's still interesting enough. Anyway, I have a bed for you, and I will definitely sell it to you. ”

Lesis is a warm-hearted person, and it's not a bad thing to know two rich ladies, but if it's a high-consumption thing, it really has to be taken by a rich person. They are familiar with that circle, and they know a lot of people, and they will definitely be able to come in handy in the future.

After eating, Tang Wanwan told Mrs. Chen to wash the dishes and chopsticks quickly and clean up everything else.

Then help her peel out all the camellia fruits she brought back, then put them on a grinding disc and grind them, and give them to her, and she will use them to extract oil.

These preparations take a lot of time. Tang Wanwan used this time to tinker with her oil press. How to do the oil press, she calculated all the way from Xishan to the way back, and it must be simple and easy to operate.

If this is done well, it may be able to open up a way for her to make a fortune. Oil presses, juicers, meat grinders, even dishwashers, sewing machines, these household machines, once they are ready, if you want to open up sales, it is not too simple.

Tang Wanwan left Master Feng and Gu Xinyu today, but they actually have their own little selfishness. It is to let them personally witness how they can make the most powerful and practical things in the shortest time.

In Tang Wanwan's Jin Luban Codex, there are many records of ancient artifacts and some uses. Tang Wanwan has seen about the ancient method of extracting oil from wood. This set of methods seems to be applicable, and it is very difficult for families to operate.

In fact, the principle of oil extraction is very simple, it is nothing more than to fry the camellia fruit, then grind it into a fine powder, and then the camellia oil in the fine powder is squeezed out of the oil by strong pressing. Because it is a manual physical oil extraction method, the efficiency is slow, and it is very labor-intensive. Generally, oil presses are operated by some powerful and very stout men.

They hollowed out the inside of a very large piece of wood and then installed wedges one by one on the belly of the wood. There is an oil outlet and an oil tank below, an oil outlet and an outlet for cleaning the oil residue at any time, and when the wedge wood is hit with a huge log in the middle, the oil cake is squeezed by gravity, and the oil inside is oozing out little by little.

There is a set of oil press production in the Jin Luban Code, but Tang Wanwan feels that that kind of production still requires a lot of manpower and a lot of space. It's better to make it small and one person can do it, and that's perfect.

Tang Wanwan also used this physical pressing method, but she used the strong pressure of air. Use a straw to evacuate all the air pressure in the bamboo tube, and then press the air pressure back little by little through the switch handle. A switch valve will be installed at both ends of the bamboo tube. Pull out the door valve, and the oil residue inside can be poured out, and the oil outlet is on the side. In front of the oil outlet is a leaky screen. This prevents the sludge from falling into the clean oil.

This oil press may seem complicated, but it is actually not very difficult to do.

Others only saw Tang Wanwan holding a hammer, nails, wood, and bamboo tubes in his hands. There were also some oddly shaped small pieces of wood, less than half an hour. A small manual oil press was made by Tang Wanwan.

In fact, she thought of using this manual oil press, and her inspiration was the syringe for injections. Before the injection, all the air in the syringe is evacuated, and the syringe is pushed forward vigorously, no matter how long the tube is, it can be pushed to the end.

It turned out that Gu Xinyu and the others were going to say goodbye after lunch, and they had nothing to do, seeing that Tang Wanwan was busy working, they helped on the side and watched how she operated.

A large pile of sawn bamboo is in the yard, which is left over when building a new house. Of course, there are also a lot of wood, piled up in the hut, these are Tang Wanwan's treasures, she can watch it closely.

I saw that Tang Wanwan was holding a hammer in her hand and quietly beating it with an iron nail, looking at her as if she was doing something. Fortunately, Tang Wanwan had the foresight to let the Tan family help her make a lot of ready-made wooden blocks. There are many ready-made woods, some thick, thin, long and short, and some have strange shapes.

When Tan Song helped Tang Wanwan do this, he asked Tang Wanwan curiously, what do you want these wood to do? She replied to him: "When the time comes, you will know, she is a backup, just prepared."

"What are you doing here?" Seeing Tang Wanwan making a device for the gate valve, Le Sisi couldn't help but ask curiously.

"It's the pressure gate, you'll find out later." It needs to be connected up and down, and then it needs to be able to install the handle, if it is made of iron, it will be better, and it may be more durable. Made of wood, it is estimated that it is slightly inferior in durability.

"And what are these two mouthfuls for?"

"It's the oil outlet, and the waste outlet. When it's ready, I'll do it for you. Xinyu, please see if my mother is ready?

"Okay." Gu Xinyu got up.

Lord Feng also looked very carefully, and asked a few questions puzzled, Tang Wanwan answered his words very patiently, and Lord Feng couldn't help but be surprised after hearing it: "Doesn't that mean that if you do a good job of this manual oil press, we can squeeze oil at home?" ”

It was the first time for Tang Wanwan to see Lord Feng so excited, so she replied with a smile: "Yes, your lord, you are not wrong. ”

"Okay, okay, then you can do it quickly, if you can get this out, we will all have oil to eat in the future, and the oil extraction will be handed over to you in the future."

"Then Lord Feng wants to talk about it, right?" As long as Lord Feng can call the shots, Tang Wanwan will not have to worry about having no business to do in the future.

"It's coming, it's coming, it's all polished." "Ah Juan, take a look, maybe use?"

Chen Niangzi and Gu Xinyu made it together, and brought the camellia powder that was fried and ground into powder a little earlier.

"There are a lot of them, I guess, I can squeeze out a bowl of oil." Tang Wanwan looked at those ripe camellia powders and said.

"Can you do this?" Mrs. Chen was a little suspicious that her daughter made this thing, how could it look like a child's house, it looked very empty. Simply put, it's a half-human-tall bamboo tube with a strange device on it. One side can be pressed down directly with the hand, and the other device can be broken down by the hand. There were no other bells and whistles, and under the bamboo tube were two small grooves, which Tang Wanwan explained were oil outlets and waste outlets, and two small wedges were added to these two openings.

Remove the wedge to see the situation inside the bamboo tube, you can add material at any time, and you can also get out the garbage inside.
