"Yes, but now the more troublesome thing is how to puree the sweet potatoes!" Fang Dajun then told the process of making vermicelli.

As long as there are four kinds of machines to make vermicelli, it can basically be fully automated, one is the pumping machine, because it needs a lot of water; the second is the crusher, which needs to beat the sweet potatoes into a slurry; the third is an automatic drum, which is used to filter slag; Finally, there is a stamping machine that presses the vermicelli into shape.

Water source, filtration, stamping, these three can be replaced by labor, and the most important thing now is manpower.

But crushing is a pitfall, raw sweet potatoes are brittle, not easy to make them sparse, even with a stone mill is not easy, the soil method can only be used in the stone trough to use the principle of levers to punch with large wood, but this is too wasteful of labor, and there is no way to completely pestle into mud.

"Second sister, what do you think about smashing this? Give some advice! Fang Dajun asked with a little headache.

"Can't you cook it?" Although Fang Yan is smart, his knowledge is too limited, he can't think of any machine at all, and he doesn't have the concept of a crusher.

Fang Dajun smiled bitterly, "After cooking, the starch has condensed, how can it still be filtered out, forget it, the boat will naturally go straight to the bridge." You come and take a hand, we'll make the starch this afternoon, and we can make vermicelli tomorrow. ”

"Well, I listen to you!" Fang Yan was fooled, and reading was her Achilles' heel.

With the help of professionals, I quickly turned over the soil and got more than 30 catties of sweet potatoes, which was completely enough as an experiment.

At this time, they didn't have the heart to eat, so the two sisters then cut the sweet potatoes and cut them into diced sweet potatoes that were slightly larger than corn, without peeling, but they must be washed, otherwise there will be sediment in the final noodles.

One for coal, the other for reading, both of them were in full swing, so they had to use a stone mill to grind diced sweet potatoes into a pulp, which made it easier to produce starch than to pestle it out in a trough, and the stone mill in the village was so heavy that most women could not push it alone.

There was no way, Fang Dajun had no choice but to call the two brothers of the Qin family, digging coal can be regarded as a free job, as long as the task is completed.

As soon as Qin Shou and Qin Wuyang arrived, Fang Dajun probably explained, and the two brothers started work, and Fang Yan was responsible for adding diced sweet potatoes to the grinding hole.

The grinding is also the use of the lever principle, the stone mill is embedded with a one-foot-long wooden square, the end of the hole is punched, and then the rake is buckled above, the rake is more than two meters long, the end is hung on the beam, and the ground is kept level.

In this way, it is okay to push forward directly at the end with manpower, and the stone mill will rotate as soon as you push and pull, and the action is similar to twisting Yangge, and the action of Neo's flash bullet in the Matrix is actually imitating the grinding of Great China, uh!

Forty minutes later, the sweet potato slurry is finally OK, if there is a crusher, this sweet potato, at most three minutes can be OK, and there is no need to cut the sweet potato into cubes in advance, the machine, the machine, the four words of rejuvenating the country through science and education are really incisive!

"Army, what's going on now!" Qin Er asked excitedly, without him, because Fang Dajun promised that if the matter of vermicelli was completed, each household would have at least fifty yuan of income during the New Year, and if it was well controlled, hundreds of yuan would be possible, which was a huge amount of money!

And there is another point, although the powder residue left after filtration cannot be sold for money, but it can be used to feed livestock, and it is not a problem for each household to fatten a pig with the powder residue, which is dozens of dollars.

Although the villagers don't have red lotus to eat, they can buy nearly 1,000 catties of rice to eat with more than 100 yuan, which is a luxury!

"Filter!" Fang Dajun said happily.

The division of labor immediately began, Qin Er was responsible for going to the well to fetch water, Qin Dalai shook the linen cloth for filtration, Fang Yan was responsible for adding, and he was a patient, so he was responsible for guiding the work.

A wooden frame in the shape of a "well" is hung on the beam, the height is just at the elbow of Qin Da, this position is the most labor-saving, and a square linen is tied to the four corners of the "well" frame, which becomes a suspended funnel.

Under the funnel is a large vat, the soil is burned, and every household in the village has the blessing of the brick field, and then the ground sweet potato pulp is poured into the burlap funnel, and then the water is also poured into it.

Qin Da grabbed the two corners of the wooden frame with his hands and began to shake it, and the second sister Fang Yan added water to it from time to time, and when the water flowing out of the funnel was no longer muddy, it was finished.

If the sweet potato pulp in the funnel was the size of a basketball just now, and now it is the size of a football, the shrinkage is not too much.

"Dajun, why is this starch different from what is sold in the town?" Qin Da looked at the things in the sackcloth and asked suspiciously.

Fang Dajun suddenly shuddered and said with a smile: "What is in the hemp cloth is powder and slag, and what leaks is starch." ”

"What? You say the water in this tank is starch? Qin Da's mouth was wide open, completely incredulous.

Qin Er also ran over and shook his hand in the tank a few times, but he didn't touch anything, it was all water, "Dajun, aren't you joking!" ”

"I see!" Fang Yan suddenly exclaimed, "What my brother means is that after these white water precipitates, it is starch, right?" ”

Fang Dajun said with a smile: "That's right, that's what it means, now the starch has basically been filtered into the water, and when it settles down, the bottom layer is starch." This precipitation will take a long time, go find a dustpan and cover it, so that the wind does not blow into the sand, and tomorrow morning it will be about the same. ”

"It's going to take so long?" Fang Yan was a little surprised.

Fang Dajun said helplessly: "No way, if there is a drum machine, you can use the water source repeatedly, but there is too much water used to filter it with this soil method, more than ninety percent of this large tank is water, and if you want to completely precipitate, it will take ten or so hours at the earliest, so you can only wait for tomorrow morning to make vermicelli......"

A pound of sweet potatoes can't produce two taels of sun-dried starch, and the remaining eight taels will basically not be consumed, which is the powder residue.

"Second sister, you take the powder and slag to feed the pigs." Fang Dajun proposed, although theoretically it is said that the powder residue can be fed to pigs, it also depends on whether pigs like to eat it.

"Well, let's try it!" As she spoke, Fang Yan scooped up a small half scoop of flour and went to the pigsty, and the three of them also went over to take a look.

There is only one pig in the pigsty, that is, **ten pounds in size, which is pitifully thin and has been raised for more than half a year.

"Whoa!" As soon as the powder was poured into the trough, the lean pig immediately ate it fiercely, flicking its tail and eating very happily.

Dozens of seconds later, the groove had slipped away, and the skinny pig kept shaking its ears and flicking its tail, whining.

"It's done, it can be used to feed the pigs!" Fang Dajun said happily, don't look at the starch that has been filtered out, but there is also nutrition in the slag, and the pig will naturally grow meat faster after eating it.

"Dajun, you're amazing!" Qin Er said with some admiration.

But Fang Yan still expressed her opinion, "Of course, this point of powder slag pig can be eaten now, but when the time comes, how to preserve the powder slag when it is made in large quantities?" Do you want to dry it, there is not such a good weather to dry in autumn and winter. ”

Fang Dajun said with a smile: "Don't be so troublesome, just keep the powder residue as kimchi, scoop a little out every day and mix it with pigweed, you can feed it for a long time, enough to fatten the pigs." ”

"Keeping it as a pickle?" Fang Yan frowned, obviously not understanding.

Fang Dajun directly disdained: "How did you learn chemistry in junior high school?" You can still be admitted to high school, the powder slag originally contains water, as long as it is mixed with salt, it can be fermented, and it can be stored for several months after sealing, although there is no such big jar to completely seal, but there is no way, even if it is a little smelly, it is estimated that the pig still prefers to eat, as long as it is cooked, you don't have to worry about the pig's stomach. ”

"Brother, since you are so proficient in mathematics, physics and chemistry, why can't you even pass the high school exam?" Fang Yan was very surprised.

Fang Dajun really wanted to say: "Don't be infatuated with my brother, because my brother and I are a legend!" ”

"Second sister, what do you think, it's been seven years since high school and college, isn't this delaying my time to find a daughter-in-law. I don't study anymore, so I can find a daughter-in-law at any time. ”

"Color! I don't know who to learn from badly, so I won't tell you, I'll go and heat the rice. Fang Yan said and ran away.

Fang Dajun smiled, and arrogantly beckoned the two brothers of the Qin family to stay and eat together. After the vermicelli can make money, he will be able to respond to the call in the production brigade, and now it does not occupy the time, but it occupies the geographical advantage, people.
