"The folks at that time are okay..." When Grandpa Four talked about past events in his free time, he would sigh with his pipe and pot.

"At that time, when the folks came to squeeze oil, they all dried and selected the raw materials at home before pulling them over. This saved us a lot of things. At that time, the folks pulled the oil into the oil mill, and they would take the raw materials. Weigh it and record it in the account, and divide the oil in proportion after the squeezing. The folks with few raw materials simply don’t squeeze the oil, but just exchange a few kilograms of oil and leave."

　　 I remember the words of Grandpa Fourth. Those folks were really good at that time. After all, the preparations for oil extraction were quite cumbersome. Just sifting and drying is a very laborious task.

　　 But these jobs were done in advance by the folks. Those years saved a lot of time and energy for the workers in the oil press.

　　 Shixiong remembers very clearly that the oil press at the Fourth Grandpa’s house contains more oil than the oil press he has come out now. Regardless of the thickness of this oil press, it is a lot shorter, so the oil cake tank can only hold three hundred and sixty kilograms of oil at most. And the oil press of Grandpa Si's house was able to hold four hundred and fifty catties of oil back then.

　　The most important thing is that after the folks come to the oil press, they will spontaneously help as long as they can. Some help to prepare firewood, some help to push the ground material, some help to steam the powder, some help to press the plate, and some help to squeeze. Anyway, none of the folks who came to the oil mill were idle.

　　 The folks of that era were really like a family, unlike the next twenty years, even if the feelings between the folks have become weak...

　　 "Yeah, this oil is getting more and more."

　　 "This oil is really clear, much clearer than the oil refined from fatty meat."

　　 "This oil should be delicious."

　　 "You only know how to eat. You didn't hear the guardian say that this oil is used for cooking. But what is cooking? Is it delicious..."

　　 The turbulent sound of discussion pulled Shi Xiong back from the memory.

　　 He can't help sighing a little bit emotionally.

　　 The fourth grandfather has passed away a long time ago, and he has also inexplicably passed through this era, and his parents and little sisters will never be seen again...

　　 shook his head, tossing away the sadness in his head, Shi Xiong walked to the oil press and squatted down, carefully watching the first basin of oil he had squeezed out in this era.

　　 This pot of oil is called "top oil" according to the old name.

However, because the first-squeezed oil is squeezed by steaming the flour grains to raise the temperature, the first-squeezed oil has heavier moisture, muddy color, bad appearance, and easy to accumulate oil, but it is fragrant when used for stir-frying vegetables and deep-fried tofu. Very much.

　　 In fact, not only the first squeezed oil, even the second squeezed oil tastes not top-notch. The reason is very simple. Grandpa Four said that for this kind of oil squeezed by wood squeezing method, it is best not to contact the oil with metal objects. Only the oil squeezed out like that is called an incense. But the metal ring is used when pressing the plate, even if it is the best metal, once it comes into contact with the oil, the taste of the squeezed oil is not pure.

　　 The Fourth Grandpa also said that when wood press was used in some southern provinces, the pressing plate was not made of iron rings, but bamboo sticks were used to make bamboo plates. This kind of oil cake made with bamboo plate, the oil is more fragrant.

　　 But in this era, in such a backward Indian tribe, it is already very good to be able to squeeze vegetable oil. As for the taste, let's let it go first.

After Kuaima completely smashed the second wooden wedge into the squeeze chamber, more and more oil leaked down the oil drip hole. It didn’t take long for him to pick up two large pots, which were sixty or seventy. Jinyou.

　　 When the oil stops dripping, the pressing process is complete.

　　 However, the oil cakes left over from the oil pressing can still be used for the second pressing, but that requires some preliminary work.

The wooden wedge squeezed the wood block in the squeeze cabin very tightly, but that’s okay. At the other end of the squeeze cabin, Ishikuma held a hammer in one hand and a slender wooden wedge in the other hand, aiming at the one that was smashed in at the beginning. Hit the wooden wedges lightly with a hammer a few times and the two wooden wedges will be easily smashed out.

　　 After all the wood blocks in the squeeze cabin were taken out, the twelve oil cakes in the oil silo were completely squeezed together, and it was difficult to break them apart by hand. At this time, the hammer and the long slender wooden wedge in Shixiong's hand were useful again.

　　 Align the gap between the two oil cakes, smash a few hammers lightly, and the oil cakes squeezed together will be separated.

　　 Then he uncovered the dry thatch wrapped around the oil cake, took out the oil inside, and continued to put it in the stone mill and grind it again, in order to crush the remaining oil more thoroughly.

After 　　 is finished, it will continue to be steamed in the pot again. This is the second steaming in the "one frying and two steaming" process in the oil extraction process.

　　 After the steaming, the oil will be pressed again, but this time the press is tighter than the first press. Not only does it need to be smashed with a mallet, but even with a foot.

　　 Finally, these oils were pressed into twelve oil cakes again ~ lightnovelpub.net ~ squeezed again for the second squeezing.

　　 As the two wooden wedges were smashed into the squeeze cabin again, the clansmen who were watching the excitement around were again surprised to find that the oil began to drip again.

　　The oil dripped this time is the second squeezed oil. Compared with the first pressing oil, the second pressing oil is more clear and tastes better.

　　 The amount of second-squeezed oil is a little less than that of first-squeezed oil, but it is 50 or 60 catties.

　　 A total of less than 130 kilograms of peanut oil was squeezed twice, and the oil yield reached 35%!

　　 The oil output rate is already very high, especially when using this wood press technology to press oil, the oil output rate can be 35%, which is already very high. Don't forget that the peanuts used in this oil extraction are not specially cultivated peanut varieties specially cultivated for oil extraction with a high oil yield of 45% in later generations.

　　 Regardless of whether it is the first press or the second press, filter it again to filter out the impurities in it, then peanut oil that is almost identical to later generations will be completely published.

　　 At this time, the tribesmen were allowed to step forward and watch the freshly baked peanut oil up close.

　　 The fragrant peanut oil naturally aroused the people's sigh.

　　Oil pressing is over at this time. Although the oil yield of peanut kernels is quite high, it usually ends after pressing twice. No amount of oil can be squeezed out.

　　 But the peanut meal left over from the oil can not be thrown away. This thing is also a good thing.

　　 is like the soybean meal left over from soybean oil extraction in later generations. It is an excellent material whether it is used as fertilizer on the ground or as feed for livestock.

　　 This is the same with the peanut meal left over after the oil is squeezed. If used on the ground, the effect is no worse than later generations of chemical fertilizers. And feeding cows mixed with forage can make the tamed bison in the tribe eat happily.
