"Okay, okay, I have no problem. What about you, Xinyu?" Le Sisi and Gu Xinyu are also very interesting best friends. They obviously have different personalities, but they can play together, and their relationship is particularly good.
.
"You're not afraid of causing trouble to Ah Wan and the others. If you come to stay, we have to bring some things over."
"Miss Xinyu, it's okay to care how many meals you have. Besides, you can't eat much." Tang Wanwan said with a smile.
"Have you noticed, Ah Wan is quite interesting. Anyway, I've bagged your bed, and I will definitely sell it to you."
Le Sisi is a warm-hearted person. It is not a bad thing to know two rich young ladies. If it is a high-consumption item, it really needs to be picked up by rich people. They are familiar with that circle and know a lot of people. They will definitely do it in the future.
Can come in handy.
After finishing the meal, Tang Wanwan asked Mrs. Chen to quickly wash the dishes and chopsticks and put away everything else.
Then he helped her peel out all the camellia fruits she brought back, then ground them on a millstone and gave them to her, so that she could use them to extract oil.
These preparations took a lot of time. Tang Wanwan used this time to tinker with her oil press. She had planned how to make the oil press on the way back from Xishan. It must be simple and easy to use.
operate.
If this is done, it might open up a way for her to make money and get rich. Oil press, juicer, meat grinder, even dishwasher, sewing machine, these household machines, once they are done,
If you want to open up sales, it shouldn't be too simple.
Tang Wanwan left Master Feng, Gu Xinyu and the others behind today because she actually had some selfish motives of her own. She wanted them to witness for themselves how she was able to create the most powerful and practical thing in the shortest time.
Tang Wanwan and others have a lot of records about ancient artifacts and utensils in the Jin Luban Codex. Tang Wanwan has read about the ancient method of making oil using wood. This method seems to be applicable.
It is very difficult to operate at home.
In fact, the principle of oil extraction is very simple? It is nothing more than frying the camellia fruit? Then grinding it into fine powder, and then pressing the camellia oil in the fine powder to produce oil. Because it is a manual physical oil extraction method? Not to mention the slow efficiency
? It also consumes a lot of manpower and material resources. Generally, oil presses are operated by strong and very strong 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 was an oil outlet and an oil tank left underneath? One oil outlet? One is an outlet for cleaning oil residue at any time. In the middle
When hitting the wedge wood with a huge log, the oil cakes will be squeezed by gravity, and the oil inside will seep out little by little.
There is a set of oil presses in the Jinluban Code? However, Tang Wanwan felt that that kind of production still requires a lot of manpower and a lot of space. How about making it a small operation that can be completed by one person? That would be perfect.
Tang Wanwan also used this physical squeezing method, but she used the strong pressure of air. She used a pipe to evacuate all the air pressure in the bamboo tube, and then used the switch handle to press the air pressure back bit by bit.
.A switch valve will be installed at both ends of the bamboo tube. If the valve is pulled out, the oil residue inside can be poured out? There is an oil outlet on the side. There is a leakage net in front of the oil outlet. This can prevent the oil residue from falling into the clean oil.
in.
This oil press seems complicated, but it is actually not difficult to make.
Others only saw Tang Wanwan holding a hammer? Nails, wood? Bamboo tubes, and some strange-shaped small pieces of wood. In less than half an hour, Tang Wanwan had built a small manual oil press.
In fact, she thought of using this kind of manual oil press? Her inspiration was the syringe used for injection. Before the injection, evacuate all the air in the syringe? Push the syringe forward hard, no matter how long the tube is, it can be pushed
in the end.
It turned out that Gu Xinyu and the others were saying goodbye after lunch, and there was nothing else to do. Seeing that Tang Wanwan was busy, he helped while watching how she operated.
There was a large pile of sawn bamboo at home in the yard, which was left over from building a new house. Of course, there was also a lot of wood piled inside the hut. These were Tang Wanwan's treasures, and she watched them closely.
At this moment, I saw Tang Wanwan holding a hammer in her hand and quietly beating with nails. She seemed to be doing something. Fortunately, Tang Wanwan had the foresight and asked the Tan family to help her make a lot of ready-made wooden blocks. Ready-made
There are many pieces of wood, some thick, thin, long, short, and some with strange shapes.
When Tan Song was helping Tang Wanwan do this, he curiously asked Tang Wanwan what he wanted the wood for. She answered him: You will know when the time comes. She was just a backup to be prepared.
"Awan, what are you doing?" Le Sisi asked curiously when she saw Tang Wanwan making a valve device.
"This is a pressure gate valve. You will know about it later." It needs to be connected up and down, and then it needs to be able to install a handle. It would be better if it was made of iron, which may be more durable. If it is made of wood, it is estimated to be more durable.
A little bit worse.
"Then what are these two little mouths used for?"
"This is the oil outlet and the waste outlet. After it is done, I will operate it again for you to see. Xinyu, could you please check if my mother is ready?
"Okay." Gu Xinyu stood up.
Lord Feng also looked at it very carefully and asked a few questions without understanding. Tang Wanwan answered him very patiently. After hearing this, Lord Feng couldn't help but said in surprise: "Doesn't that mean that if you press oil by hand?
Once the machine is ready, we can press the oil ourselves at home?"
It was the first time that Tang Wanwan saw Lord Feng so excited, so she smiled and replied, "Yes, Lord, you are right."
"Okay, okay, then do it quickly. If you can get this out, we will all have oil to eat from now on, and I will leave the oil extraction to you."
"Does Mr. Feng keep his word?" As long as Mr. Feng can make the decision, Tang Wanwan will not worry about running out of business in the future.
"It's here, it's here, it's all polished." "Awan, take a look, maybe it can be used?"
Mrs. Chen and Gu Xinyu made it together. They arrived a little early and brought the roasted and ground camellia powder.
"There are quite a few. I estimate it can squeeze out a bowl of oil." Tang Wanwan looked at the cooked camellia powder and said.
"Then can you do this?" Madam Chen was a little suspicious of what her daughter had made. It felt like a child playing house, and it looked very fake. It looked simply like a bamboo tube about half a person's height, with words added on it.
I got a strange device. One side can be pressed down directly by hand, and the other device can be pulled down by hand. There are no other fancy things. There are two small grooves under the bamboo tube. Tang Wanwan
Explain what the oil outlet and waste port are, and there are two small wedges added to these two ports.
When you remove the wedge, you can see what's going on inside the bamboo tube. You can add ingredients at any time, and you can also take out the garbage inside.
