Chapter 177: Cutting rapeseed with a sickle, hit by a 600 kilogram boulder
Naturally, it was impossible for Li Xiang to work alone to support the whole company, and Yao Yao was just joking to liven up the atmosphere.
Mainly in terms of farm work, Li Xiang is the best, so Li Xiang is basically doing it. Several girls want to help, but Li Xiang dislikes them and gets in the way, so they can only act as cheerleaders on the side.
The three girls were actually of great help to Li Xiang. Now Li Xiang left all kinds of trivial matters to them.
For example, Li Xiang would check the accounts of several stores and leave it to them to take care of everything.
Usually express delivery, tracking, and after-sales are all handled by them.
In order to enrich the three girls, Li Xiang also provided them with a benefit, allowing them to sign up for some online courses that they are interested in, such as management, or online adult undergraduate courses. One is to get a diploma; The second is to improve one's own skills and recharge.
A diploma is more of a "qualification" thing. For example, when telling people, I graduated from such and such university, I graduated with a bachelor's degree to enhance my image. It sounds better than saying you graduated from high school.
As for correspondence universities, if you study seriously, you can also learn a lot of knowledge.
The three girls are all relatively pragmatic. Li Xiang reimbursed their tuition fees, which moved them so much that they even wanted to commit themselves to them.
They were unable to enter college because of their family background, so they had to enter the society early to work. Now that they have the opportunity to fulfill their dream of obtaining a degree, the three of them still cherish it.
Rapeseed is actually divided into spring rapeseed and winter rapeseed. In places with severe cold climates such as the Northeast and Northwest, they are often sown in spring from April to May and harvested in autumn from October to November. In places with warm climates, such as the south, the middle and lower reaches of the Yangtze River, Sichuan, Hubei, Hunan, etc., winter rapeseed is often planted, sowing from October to November every year and harvesting from May to June of the following year.
Li Xiang is from Sichuan Province, so he grows winter rapeseed.
Because the growing season and growth cycle are different, the varieties are also different. Winter rapeseed is mostly cabbage type, while spring rapeseed is often cabbage or mustard type.
Because winter rapeseed has a longer growth cycle, its oil content is higher, between 35% and 50%, while spring rapeseed is usually 25-30%.
Li Xiang harvested the rapeseed, dried it and threshed it, and then used a "windmill" to remove some broken leaves and dust to obtain clean rapeseed.
He planned to record a video on ancient oil extraction, so he invited Li Jinyu, Li Yucheng, Jiang Jianguo and others. In addition, Grandma Li Xiang, the third wife, and some older people in the village who had pressed oil before also came. Come visit, join in the fun, and provide some technical support and advice.
The location was chosen in a corner of Li Xiang's backyard and a large shed was built.
Jiang Jianguo and Li Yucheng helped make the wooden frame of the oil pressing equipment. Li Xiang was strong and knew some simple carpentry work, so he also came to help.
The main structure is made of thick pine wood.
Then many places need to be hooped with steel, which needs to be very strong, otherwise it will not be able to withstand the impact. Jiang Jianguo is responsible for forging these iron hoops and fastening parts.
Li Jinyu and the others, who are older, are responsible for technical guidance.
After two days, a five-meter-long, 70- to 80-centimeter diameter wooden and iron-structured oil-pressing device was successfully built.
Clean straw is also prepared to wrap the rapeseed.
The first step in oil extraction is to make the dough.
There are hidden mysteries in this process.
The ground rapeseed is placed in a steamer, fumigated with steam, and then fried. The control of moisture and temperature is very particular. If it is too dry, the oil cannot be squeezed, and if it is too wet, the oil cannot be squeezed. This all depends on Experienced.
Lijia Village has not practiced this ancient method of oil extraction for many years. It is usually transported to the town and used in a specialized oil extraction workshop to extract oil using machines. That one is more efficient.
Li Xiang does this mainly for traffic, and it can be regarded as an inheritance of intangible cultural heritage skills.
Then the rapeseed oil squeezed out by this method is more fragrant and of better quality.
Pour the fried rapeseed powder into the rice straw, put an iron ring on the outside, and wrap your feet in the cake.
Of course, it’s impossible for old men to play music. Like Maotai, it is said that young girls play music.
But the female workers at the Maotai Distillery are definitely not as good-looking as the three girls at Li Xiang's side.
Three beautiful girls, Yao Yao, Zhao Xueqing, and Lei Xiaohui, appeared on the scene. They washed their feet, stepped on the cake with bare feet, and laughed like silver bells while working. They were all young girls in their twenties. I have to say it is a beautiful scenery.
Li Xiang installed the "rapeseed cake" they stepped on into the pressing chamber, and then started the oil pressing process.
This is Li Xiang's home court.
His upper body was bare, and his tendons and flesh had clear lines. Each piece was carved like a work of art, and he was dancing with a huge stone hammer weighing more than 600 kilograms, hitting the wooden wedges one by one.
Generally, a traditional oil pressing workshop uses a hammer of one to two hundred kilograms, which is quite powerful. It also needs to be suspended from the roof beam, which is convenient and labor-saving. Some even use only a thick wooden pillar, like a temple hammer. It's like a bell, but Li Xiang directly used boulders of more than 600 kilograms here, which is more efficient.
If others need to bang for three hours, he may need more than one hour.
Originally, this was physical labor, very hard work, it could be said that it was two drops of sweat and one drop of oil. But here with Li Xiang, it's just like playing.
In fact, the heavier Li Xiang is not strenuous, but if the force is too great, the equipment will not be able to bear it. If it falls apart after a collision, wouldn't it be in vain?
And if it is too heavy, it will be too shocking.
This pure force exerts huge pressure on the green cake in the pressing chamber. Relying on this physical pressure, the bright yellow rapeseed oil, which looks like golden liquid, gurgls down.
Three girls jumped barefoot on the clean slate next to them, cheering: "Oil comes out, oil comes out~"
"We succeeded~"
Li Xiang was also very pleased that the oil came out successfully on the first try.
Seeing this, other participants also applauded in celebration.
Li Xiang continued to dance and hit the boulders. This process required repeated squeezing and lasted for at least an hour to allow the rapeseed oil to completely flow out.
The "boom" sound of impact resounded throughout the backyard. Many tourists were attracted by the earth-shattering and rhythmic sound. They followed the sound and entered Li Xiang's backyard to visit, comment and shoot videos.
Some tourists questioned: "Are you using props for filming? Are they actually made of foam?" Li Xiang put down the boulder and made an invitation gesture: "Come on, come on, come and try it."
The questioning tourists stepped forward and were dumbfounded: "Here I go, it's so heavy, what a guy! I can't handle it, I can't handle it!"
"Admire, admire!"
The tourists were all doubtful. When Li Xiang operated again, they cheered and applauded.
"This young man is amazing, he is really a strong man!"
"It's several hundred kilograms, right? It should be three to four hundred kilograms, right?"
In fact, it was more than 600 kilograms. Li Xiang didn't explain it, he just smiled.
A visitor who had followed Li Xiang before explained: "This is Brother Xiang, the most powerful pastoral blogger on the entire Internet! A figure admired by many people in the martial arts and weightlifting circles. If you don't believe it, search for his previous killing of a wild boar. The video, that guy, is so violent! ”
"I really can't believe that such a well-proportioned figure can actually contain such amazing power."
The clips that tourists questioned are also included in the video, which adds to the authenticity and credibility.
Of course, after the video was uploaded, some fans would inevitably be suspicious, saying that these people must have been hired to create the video effects.
Check out the 16-9 book bar and see the correct version!
Some fans will explain that if you look at the vibration of the wooden wedge, the vibration of the oil extraction equipment, and the seepage of bright yellow oil, you will know that this is a real impact.
But those people still don't believe it, saying that vibrations can be video special effects, and even 50-cent special effects are exaggerated, so why are you bragging?
There is nothing you can do when you encounter those bullies.
……
The uploading of the video is a later matter. At this moment, Li Xiang was pressing oil. An hour and a half later, he ended the labor (practice) and came over to check the rapeseed oil.
He scooped it up with a spoon and let it flow down slowly. It was golden and translucent, and exuded the unique rich aroma of rapeseed oil. It seemed to be of quite good quality.
At the last weighing, the total oil output was a little over 48 pounds.
Zhao Xueqing pressed the calculator and said: "The rapeseed invested before was 121 kilograms. About two and a half kilograms of rapeseed will yield one kilogram of oil."
Li Xiang nodded. He had consulted Li Jinyu and others before, and it was almost the same ratio.
The rapeseed he harvested before was only 121 kilograms, which was relatively small and could be dried in one operation. Therefore, Li Xiang went to the village to buy some more rapeseed and squeezed enough oil for his family for a year.
A total of more than 300 kilograms of rapeseed oil were squeezed and stored in the cellar.
Then Yao Yao, Zhao Xueqing, and Lei Xiaohui also brought rapeseed from home to find Li Xiang to press oil.
The rapeseed oil hand-pressed by Brother Xiang is naturally healthier than the purchased one. Moreover, seeing Brother Xiang take off his clothes and work, the visual effect of his body covered with tendons and flesh is a beautiful enjoyment, and the three girls find it particularly eye-catching.
Yao Yao, in particular, was quite bold. Occasionally she would come over and touch her with a smile, just to enjoy her hands and make a joke.
Not to be outdone, Lei Xiaohui also went up and touched a few handfuls. Li Xiang scolded them and told them to move away to avoid hitting them.
The boulders weighing more than 600 kilograms were dancing around, causing injuries and fractures when touching each other.
Zhao Xueqing also wanted to touch it, but she was too shy and didn't dare to do it. She felt that she was at a disadvantage.
Naturally, Li Xiang didn't charge them any processing fee, because they also participated in the video shooting and helped with the pie.
The remaining oil cakes from the oil extraction were also returned to them, and they were fermented and used as fertilizer to grow vegetables and flowers.
The rapeseed grown by Li Xiang and the villagers is truly pesticide-free. It is pure green and pollution-free. No additives are used when extracting the oil. Pure pressing is used, and the straw is washed and dried. It is a truly pure natural green cooking oil, which is safe to eat.
Many oils on the market, produced by factories, often use the leaching method, which is to use organic solvents (extraction such as n-hexane), such as soybean oil, corn germ oil, rice bran oil, etc. Because these raw materials themselves contain little oil, they are not suitable for direct pressing.
Things like peanuts and rapeseed are pressed.
However, in order to save resources and pursue efficiency, modern enterprises will again use the leaching method to produce oil from the pressed oil cake.
Because there is a lot of oil left in those oil cakes, they will not be used directly as fertilizer like in rural areas.
It can be said that it is utilized to the extreme.
Therefore, some inferior rapeseed oil and peanut oil are obtained by leaching the pressed cake residue with organic solvents.
This organic solvent is also graded. The cost of No. 6 light gasoline (mainly containing n-hexane, cyclohexane and other hydrocarbons, with more complex composition) is definitely lower than using high-purity n-hexane.
In the leaching process, solvent residues are inevitable and are basically impossible to completely remove.
Therefore, after the tanker truck is loaded with kerosene and gasoline, it is then used to load cooking oil, which has a "technological basis".
Their oil tank trucks were originally used to transport solvents to those factories. They were brought over, unloaded, and then filled with cooking oil, seamlessly.
The upper limit of solvent residues is stipulated in the national standard. Generally, if it does not exceed the standard and complies with laws and regulations, it can be sold normally.
From the perspective of syndrome differentiation, the existence is reasonable. The demand for edible oil is too great. If only the pressing method is used, all oils are high-quality oils, which will lead to many people not being able to eat oil and not being able to afford oil.
However, even if it does not exceed the standard, if it is loaded with that kind of oil tanker, it will not exceed the standard.
