Volume 1 Chapter 57 Oil Extraction

The next important task was to dig out the earth kiln needed to fire the bricks and tiles, which was also a huge project that was difficult to complete without ten days and eight days.

The reason why this project has been put to the present is also because the bricks and tiles need a lot of time to dry, and the gap during this time is just right to be used!

The location of the kiln must be carefully considered, its relatively large amount of work, the hardness of the soil and the degree of trouble when firing the kiln, and the distance from the house are all conditions that need to be taken into account.

I don't want to spend days halfway through the project and have my work wasted due to geological issues, mainly because I was worried that there would be large rocks in it that could not be shaken.

I don't want to be too far away from the house, so that it will not be too difficult to install the kiln and move out of the kiln, after all, there are a lot of bricks and tiles and they are very heavy, so it is especially important to make a better choice!

After some consideration, I chose the edge of the hilltop clearing, less than 30 meters from where the house was built, and the excavated earth could be poured directly on the outside slope to reduce my workload, and the distance was also appropriate.

In addition, one of the main reasons for choosing the slope is that if it rains, the rainwater will flow directly out of the place where the fire is burned, and if the kiln is dug in the center of the flat ground, the result of each rain can be imagined......

I remember when I was a child, I also had a brick kiln at home, with my limited knowledge, it was a little difficult to think about how much of a kiln I wanted to play, and I could only recall the appearance of the kiln in my mind, and it was the easiest and most risk-free way to draw a gourd!

When I was a child, the diameter of the brick kiln at home was about two meters and a half, and the depth was close to three meters.

The size of the cave is already operated by many people, one person will be very difficult, I have reduced the size of the kiln a lot, the diameter is about two meters, and the depth is planned to be two meters three.

......

What I think of is that the big is good, the small is wonderful, the size is small, the firing time is less, and more bluntly, I don't want to spread the stall too big and waste physical strength and time, this kind of physical work is not so easy!

All the preliminary work was no problem, and the start of construction was no longer delayed, and the dredging work was monotonous and boring, and I temporarily interrupted the digging after three days.

The fatigue of mere dredging is one aspect, and the main reason for the shutdown is that the fish ponds have been empty recently due to the huge consumption.

In addition, the temperature is also dropping rapidly, and winter is approaching, digging kilns and burning bricks must also make way for food at this time, after all, food is the main dependence on survival.

Taking advantage of the hot weather in the last period, the priority of these days is to stock up on a certain amount of fish for the winter first.

Fishing is just a recreational activity, if you want to fish quickly, you still have to rely on the way of fishing nets into the sea, although tired is a little tired, but if you are lucky, a net of fish is worth fishing for a few days!

It's just that today's luck is obviously not very good, the first net doesn't even have a palm-sized fish, and it is completely empty-handed, which is disappointing!

In the afternoon, the second net finally did not run in vain, harvesting about 20 catties, and kept going to the sea twice a day for the next two days, and the fish pond was filled again with three days of hard work, and finally reached a weight of nearly 100 catties.

One of the most eye-catching is a grouper that weighs more than five pounds, and I can't wait to eat it at this moment, especially when it is made into sashimi.

The kiln digging continued, fortunately, with the help of hoes and shovels greatly improved the efficiency, but the copper hoe was only about 20 centimeters left after a few months, it seems that the copper material can not adapt to the high-intensity operation, and it will be completely eliminated after the kiln is laid!

The mood of digging the kiln again after three or four days is different, as if I have just started school after a holiday, and I don't have the disgust of doing the same thing in a row.

Fortunately, there is no huge stone to dig down, and it is still gratifying to have a success, but I don't know the bottom of my heart before digging.

......

The shape of the excavated cave also needs to repair the entire cave wall and bottom and tamp it, otherwise when it rains, people have a worry about whether the side will collapse and be scrapped directly, and the kiln is not easy to operate if it is not smoothed.

This step stumped me, because I didn't have the right tools, and in the end, after thinking for a long time, I still used a thick wooden stake with a bowl mouth of dozens of centimeters to get things going.

After a week of dealing with the dirt, the brick-fired cave was finally built and ready for use, and time did not stop waiting for me, and it was already the beginning of November!

The new kiln had just been built, and I was originally going to burn bricks immediately, but I rejected it, because digging the kiln is physically and mentally exhausting, and I wanted to take some time to do something light to slow my body!

After thinking about it for a long time, there seemed to be a lot of urgent things, but the top priority was to run out of oyster sauce.

Of course, there is a pack of chicken essence in the next few months to replace its role, and the seasoning is not so urgent, mainly because cooking without oil is always not fragrant, so I plan to squeeze out the peanut oil, and it is time for it to shine!

Although the peanuts have been tossed back and forth for a month or two since they were recovered, the time is not long and the preservation is still appropriate, and the peanuts at home have not yet molded and sprouted, but they have not been left to play a role.

If it weren't for the typhoon, I might have eaten peanut oil a month ago when the peanuts were just dried.

......

The first step of oil extraction should be peanut shelling, although this step is extremely simple but also more time-consuming, in the morning it is also peeled out more than ten catties of peanuts, more than ten catties of peanuts It stands to reason that the number of oil squeezing is a little small.

But when I think about whether the first attempt can be successful or not, I don't think about the problem of a lot.

The next step is to clean the oil extraction tools, after all, there are all kinds of dirty things on it in the open air for a few months, and the things that eat to the stomach must still maintain a certain degree of hygiene, especially in this environment, colds and colds can be hard, if you encounter a big problem, you can only wait for a way to die!

The oil extraction process is also quite complicated, and the peanuts need to be fried in the machine before starting, but I have to fry them in a pot.

The frying time is not too fixed, mainly to test the eyesight and feeling, as long as it reaches seven or eight maturity, you can separate the peanut kernels and the flesh by hand rubbing.

The main purpose of this step is to allow the protein to coagulate sufficiently and denature, improving its ability to withstand stress.

It is also conducive to oil coagulation, and the more complete the protein denaturation, the higher the oil yield will be, and it is also the most critical.

The maturity of frying is not the same, and the color of the pressed peanut oil is very different, the oil yield is low if it is not fried, and the oil can not be squeezed out when it is fried, so it is very important to master the heat!

After frying, the peanuts have to be ground on the stone mill before they can be pressed, and the complete peanuts can't be oiled, and if there is a machine, it can be completed in one piece, but the operation here is really very cumbersome.

The trouble is a little troublesome, but fortunately, the hardness of peanuts is much lower than that of corn, and the speed of grinding noodles is much higher, and more than ten catties of peanuts only took more than half an hour to grind all into relatively rough peanut noodles.

At this time, you can see that the surface of the stone grinding after grinding looks very slippery, especially in direct contact with the peanut field, but I didn't expect that the first person to eat peanut oil was not me, but the stone mill.

The ground dough is wrapped in a folded mosquito net cloth with three or four layers of cloth and placed on the bottom slate of the oil extraction tool, and finally the top slate and long tree trunk are placed on top.

The next step is to verify the success of the tool, regardless of success, if it fails, the chances of trying to eat peanut oil will be infinitely reduced, because I have no better way to make this tool!

......

At this time, the mood was quite complicated, not only nervous, but also full of anticipation, as the number of stones on the rope net increased, and the weight increased, the time came to verify the results......

The trunk of the tree has been bent from straight to a certain arc, but it doesn't seem to be enough, I continued to add stones, estimated that the weight was more than four hundred pounds, and the peanut oil finally came out.

Hahahaha... Oiled, oiled!!

The hard work paid off, and my efforts were not in vain!

I was extremely excited at the moment when the oil came out, and I was looking forward to this moment for a long time, and I could finally eat the peanut oil that I had not seen for a long time, and it was the peanut oil that I planted and pressed by myself.

With hope, I am more motivated, and I am happy to see more and more grease spilling out of the slate little by little, and I am happy while continuing to add stones as appropriate.

The most annoying part is that the weight is too physically demanding, and it is especially difficult to move hundreds of pounds of stones up and down, and the next day is guaranteed to be sore after squeezing the oil!

More than ten catties of peanuts are pressed at one time, and the fat that has just come out looks relatively turbid on the appearance, and it takes several hours of precipitation to become clear and flawless.

However, the cloudiness does not affect its unique aroma in the slightest, and its aroma is intoxicating before it enters the mouth.

I didn't care about anything else, so I took a big sip into my mouth when I lifted the clay pot with oil, tasting the long-lost peanut oil.

Although the production techniques are rough and the pressing tools are simple, it is still the original recipe and the original taste, which makes people obsessed!

After a night of precipitation, the next morning I put the clear and translucent clear oil in a plastic bottle, more than ten catties of peanuts squeezed out of a total of more than two catties of less than three catties of oil, calculated down a catty of oil about two taels.

Of course, the output is not worse than the modern technology, but more than double!

Modern professional oil pressing machine can make a pound of peanuts squeeze out four taels to half a pound of oil, but think of what can you ask for under this condition, it is already a very happy thing to be able to produce oil!

With the addition of peanut oil, the status of oyster sauce has also decreased considerably, and it may be used as a seasoning in the future.

Finally solved the problem of lack of grease on the island for more than a year, and today is simply memorable!

And the peanut flour is not wasted, the peanut flour after being squeezed and dried by the modern process is almost inedible, but although the oil yield of my method is low, the peanut flour can still be eaten as food, and it is not wasted at all.
