Back in the room, Lin Fan took a look at the farm and looked at the peanuts and soybeans on the six plots of land. They were still half way from maturity. It seemed that they would not be able to wait for them to mature today.
After these two crops mature, Lin Fan plans to make peanut oil from peanuts and tofu from soybeans.
Things like oil are very scarce. The monthly ration for a Beijing household registration is only two taels. Such a small amount of oil and water is not enough to cover the expenses of a family.
The oldest man in the courtyard, Yi Zhonghai, may not be considered an eighth-level fitter in the factory, but his quota is only two taels.
So basically most families are short of oil and water. At most, they add a few drops when cooking, or simply boil it and then add a few drops.
This little bit of oil is the daily oil and water. Lin Fan was like this before, and he was even more reluctant to add oil to pickles.
You can imagine how unpalatable it is, but in this era everyone doesn't have enough to eat, so it would be nice to have something to eat.
Lin Fan came from a later generation. When going out to eat, many chefs in restaurants would use oil instead of oil.
After finishing a plate of food, the soup left at the bottom of the plate is basically filled with oil.
In the 1960s, Lin Fan didn't want to boil cabbage every day. He was not used to such a life.
It just so happens that there is a Happy Farm now, where a lot of raw materials can be grown, so that you can ensure that you have enough food, oil and water.
Soybeans are made into tofu, which has been the poor man's meat and vegetarian meat since ancient times.
The protein content is sufficient, and soy products are a very good source of protein for the human body.
Moreover, tofu is a versatile side dish. Whether it is made into a dish alone or as a side dish, it will have the same flavor as the dish it is put in.
The process of making tofu still has many derivatives, such as tofu, tofu brain, tofu skin, dried soybean paste, etc.
Now, 30 kilograms of raw materials can be received separately tomorrow, but we still need tools.
You can make a manual oil press by yourself. Making tofu is relatively simple. The difficulty lies in ordering the brine, which can be purchased directly at the supply and marketing cooperative.
The brine in the supply and marketing cooperative is salt brine, which is the mother liquor remaining in the salt pond after making salt from seawater or salt lake water. The main ingredients are magnesium chloride, calcium sulfate, calcium chloride and sodium chloride, etc., and taste bitter.
This is the brine used to make tofu in northern cities. Most of the brine used in the south is homemade and has a secret recipe.
Lin Fan had made tofu at home before, and Lin Fan followed suit. There were also videos posted online by masters about making tofu and manual oil presses. In particular, the video about handcraft masters on a certain website was highly recommended.
Lin Fan used to be very obsessed with handcrafting, watching and learning over and over again on the broken website.
But in the end, I found that after making it myself, I might as well buy the finished product, which would be cheaper.
After eating, Lin Fan turned on the light, took out a pen and paper, and drew a picture of the manual oil press. (This website has it all. If you are interested, you can search online. I won’t write it out.)
The production of peanut oil is also very simple, but it is a little more troublesome. The oil yield of manual oil press is slightly lower than that of mechanical oil press.
Generally, 10 kilograms of peanuts are equal to 4.5 kilograms of peanut oil (4 kilograms to 5 kilograms) by mechanical oil pressing, and the oil is squeezed by hand at about 3.5-4 kilograms.
However, there is a catch. After the peanut oil is successfully made, it cannot be eaten immediately. It needs to be left for a period of time before it can be eaten. This time is about 3 days to a week.
After drawing the drawing, Lin Fan put it away and went to the workshop director tomorrow to ask for steel.
Is there a shortage of steel in the steel rolling mill? A small manual oil press does not require much steel and can be done for just a few dollars.
Nowadays, many factories will produce some unplanned materials as replacement materials in the factory.
For example, if the dormitory building in the factory lacks cement, boards, etc., it can be replaced with unplanned steel materials without spending any money.
Moreover, there is a lot of scrap steel in the factory, and many workers will take or buy it from the factory. The factory also turns a blind eye to these things, since they are all used as waste anyway.
The next day, after Lin Fan arrived at the factory, he finished the morning's work and went to the director, telling him that he wanted some steel.
Because of Lin Fan's previous performance, the director immediately agreed without asking for a ticket, just five yuan, and it was made of high-quality steel.
Anyway, it was all unplanned. After getting the steel, Lin Fan packed two kilograms of apples and gave them to the workshop director. This was his direct boss. Future promotions and salary increases would be directly related to this director.
Although it is said that workers are in charge in this era, necessary interpersonal relationships still need to be maintained.
In his free time in the workshop, Lin Fan polished the parts he needed and put them directly on the back seat of his bicycle after get off work.
When he was approaching the courtyard, at the entrance of a deserted alley, Lin Fan took out ten kilograms of peanuts harvested from the farm. These were for the people in the courtyard to see, so as not to spread gossip when he used oil himself.
He just wanted to let the people in the courtyard know, did you see, this is what I made by myself, I have this skill.
After returning home, assemble the oil press and start pressing oil.
The process of extracting oil is not much, it just requires carefulness, after all, it is an imported product.
The first step was screening, but Lin Fan simply skipped this step. These peanuts were harvested directly from the farm. They were basically full and there were no bad or shriveled ones.
For the second step of rolling, you can use a stone mill to crush the peanut kernels. Do not spread the peanut kernels too thickly to avoid uneven grinding. The thickness of the ground green body is preferably 0.3 to 0.5 mm. Lin Fan directly
Crush it with your own discus.
In the third step, steam the dough. Place the crushed peanuts in an iron pot. After the water boils, spread the ground peanuts evenly on top. The steam should be even. After steaming, it requires a twist to see the oil. The moisture should be in
About 8.5%, temperature above 100℃,
The fourth step is to stack the steamed dough. It is necessary to quickly wrap the cakes and stack the cooked cakes. The cakes can be wrapped in a single circle. The upper and lower openings of the cake rings must be aligned. The grass must be spread evenly. After the cooked cakes are installed, they must be compacted and flattened.
, making the middle slightly higher.
This step is very critical. The cake must be wrapped quickly and flatly, and the stacking must be straight and upright to meet the requirements of keeping the cake gentle and extending the pressing time;
Then remember to press. The manual screw press should be placed in a heat-insulated room. After the cake is installed, press it immediately. Press it step by step, press lightly and frequently. Generally, when the oil output reaches about 90%, dismantle the press, unload the cake, and use
Use a curved knife to scrape off the edge of the cake (it should not be crushed together with the cake, it is best to mix it into the green dough and then press it in the first pass);
Crush the compact: Use a stone mill to crush the first cake with the edges scraped off, and pass it through a 3-mesh sieve until everything is screened;
After pressing once, put the compact into the oil press and press. The steps are the same, just repeat.
The crude oil obtained by pressing twice is combined and filtered, and the filtered peanut oil is ready for consumption.
Looking at the newly baked peanut oil, although Lin Fan was tired, he was very satisfied inside. Now he was short of oil.
The fragrance of the peanut oil Lin Fan was making wafted out, and the whole yard was filled with the fragrance. Suddenly, people gathered outside Lin Fan's house.
It was the scent of oil, and many people kept taking deep breaths, trying to absorb all the smell of oil and water into their stomachs.
