365 days of wilderness survival

The sisters of the Liu family came over, looked at the oil press curiously, and asked suspiciously: "Chu Feng, isn't this just a pile of wood, how do you squeeze oil?" "

Liu Yiqiu nodded thoughtfully, completely unable to understand the working principle of this oil press.

"You'll know later, it's actually very simple." Chu Feng chuckled.

He turned and went to the fireplace, where the girl was still making bread, and seven or eight finished products wrapped in sackcloth had been laid out on the side.

"Yunxin, rest for a while first." Chu Feng said softly.

"Okay, that's all that's left of the steamed ones, let me finish them first." Yun Xin replied casually, using a rope to fix the sackcloth a few times.

Chu Feng picked up the finished cakes and came to the oil press, and stuffed the oil cakes sideways into the rectangular cavity, which was the 'material trough' of the oil press.

He stuffed six or seven loaves in a row, filling two-thirds of the trough.

The Liu sisters looked at it curiously, wondering how the oil was squeezed.

The girl took the cake she had just made and stood on the sidelines and watched.

Chu Feng stuffed the empty part of the wooden contract I feeding trough, and after stuffing two pieces, he squeezed the material trough, one end against the cake, and the middle of the two wooden contracts was narrow and wide at the bottom, leaving only a small gap.

"Does that allow you to squeeze oil?" Liu Yimeng couldn't help but ask curiously.

"There's one last step." Chu Feng said softly, found the last wooden contract, stuffed the narrow end I into the middle of the other two wooden deeds, squeezed I hard in, and stuffed the wooden contract I into as much as possible.

Due to the limited space, the two wooden contracts can only be squeezed to both sides, resulting in the continuous force of the cake, which is pressed more and more compactly, and after reaching a certain critical point, the oil is squeezed out.

This is the principle of the oil press, through the extrusion of the wood contract, the cake becomes more and more compact, and it is pressed until the oil is squeezed out.

Chu Feng's hands became harder and harder, and he directly smashed Muqi with a sapper shovel behind him, causing it to sink slowly.

"Tick tock..."

There was a sound of dripping water in the clay pot, and oil began to seep out at the position of the oil outlet, falling into the bamboo trough and flowing into the clay pot.

"Oil, really squeezed out of oil." Liu Yimeng stared at Meimu and exclaimed, squatting next to the oil press and looking at the oil outlet below, and oil dripping down continuously.

"It's amazing, what is the principle of this?" Yun Xin was surprised, and also squatted on the side and watched the oil outlet of the oil press continue to drip oil.

"The principle is very simple..." Chu Feng chuckled, smashing Muqi to help the three women popularize science.

"Huh? So it was. The third woman exclaimed, the working principle of the oil press is really simple, but the effort is relatively large.

"But this method of oil extraction may only be available to you." Liu Yimeng pointed out, who else can have more strength than Chu Feng now?

"That's not all, you can also use the pile method to squeeze oil." Chu Feng chuckled.

In the same way, it is only necessary to place the oil press on its side and fix it on the ground, so that the wood is facing the side.

Then with the hanging giant wood, two or three people together, like a bell, pull the giant wood to hit the wooden contract, and this force can also stuff the wooden contract into the material trough, thereby squeezing out the grease.

This is how people in ancient times squeezed oil.

Chu Feng once again popularized science for the three women, introducing several simple methods of oil extraction.

"Chu Feng, do you know that you should also learn these from Uncle Wang?" Liu Yimeng asked with a look of amazement.

"No, this is what the History Channel taught me." Chu Feng had a serious Dao.

"History Channel still teaches this?" The corners of Liu Yiqiu's mouth tugged.

"Chu Feng, the oil doesn't seem to flow much." Yun Xin lowered her head and watched the oil flowing out of the oil outlet gradually become smaller.

"I can press some more." Chu Feng said softly, let go of the sapper shovel, turned around and picked up the tree trunk leaning against the wall.

He held the trunk and aimed at the oil press's muqi, and then smashed it down hard.

The wood itch sank down a few centimeters, and the cake sandwiched in the trough was violently squeezed and pressed, and a large amount of grease penetrated out, slipped down the oil outlet and fell into the bamboo trough, and finally all flowed into the clay pot.

In the live broadcast room, the audience brushed the barrage.

"Lying groove, just after this stick went down, my eyelids jumped."

"Don't hide from you, this stick comes down, I definitely can't afford to fall to the ground."

"It's murderous, but I like this walking 'pile driver' the most."

"Front, I suspect you're driving, but I have no proof."

"This is the ancient method of oil extraction, and few people should know this method now."

“......"

"Chu Feng, you are too ferocious, the ground is smashed and dented." Liu Yimeng pouted.

The ground touched by the oil press already had a depression, and several cracks appeared.

"The oil press won't be smashed?" Liu Yiqiu pulled the corner of his mouth, and once again recognized Chu Feng's terrifying strength.

"Oh... I'll reinforce the oil press later. Chu Feng said with a sneering smile, the strength used is indeed a little big, and it is estimated that the oil press will fall apart directly after a few more strokes.

"Ticking..." The oil outlet kept flowing grease out, and it gradually stopped after a few minutes.

"Okay, almost." Chu Feng said softly, lifting the clay pot on the ground and placing it on the table, which was already filled with the grease of the half-clay pot.

"That's a lot." The three women gathered around and looked down at the vegetable oil in the clay pot.

"Then the rest of the bread is useless?" Yun Xin pointed to the oily beans wrapped in sackcloth in the trough.

"You can take it apart and break it and stir-fry it again, and you can squeeze the oil again, that is, the tail oil." Chu Feng said softly, now what is squeezed out is the head oil, and the other squeeze is the tail oil.

"Then all the oil and beans are squeezed, and the oil we get is enough for us to eat for two or three months." Yun Xin said happily.

Only one-fifth of the oil salsa beans are used in the cake in the trough, and if the remaining oil salsa beans are made into cakes to squeeze oil, the amount of head oil and tail oil combined is amazing.

"Chu Feng, there are still a lot of oil beans that have not been dug up." Liu Yimeng's eyes lit up, and those oil beans instantly became the treasure in her heart.

"We'll dig when the snow stops." Chu Feng chuckled, oil is a very important survival resource.

He clapped his hands, pressed a wooden stick against the ground, and the other end pressed against the wooden deed through the oil outlet, and then knocked hard, and the wooden deed that was tightly plugged began to loosen, and the wooden deed was removed after several successive times.

Yun Xin reached out and took out a piece of cake from the trough, knocked it with his hand and said softly: "Hard I bangbang, can be used as a cutting board." "
