"Not bad, but now the troublesome thing is how to make sweet potatoes into mud!" Fang Dajun then told the process of making vermicelli.

As long as there are four types of machines to make vermicelli, it can basically be fully automated. One is a water pump, because it requires a lot of water; the second is a crusher, which needs to be made into mud; the third is an automatic roller, which is used to filter the slag; and finally a stamping machine that presses the vermicelli into molding.

Water source, filtration, and stamping can be replaced by manual means, and the most inexpensive thing now is manpower.

But it will be a scam. Raw sweet potatoes are crispy and not easy to turn into scattered. Even if they are grinding, they can only use leverage principle in the stone trough to use large wood to punch them. However, this is a waste of labor and cannot be completely turned into mud.

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

"Can't cooked?" Although Fang Yan is smart, his knowledge is too limited. He can't think of any machine at all, nor does he have the concept of a crusher.

Fang Dajun smiled bitterly, "After cooking, the starch is condensed, how can it be filtered out? Forget it, the boat will naturally straighten when it reaches the bridge. Come and help us make the starch this afternoon and we can make vermicelli tomorrow."

"Yeah, I'll listen to you!" Fang Yan was fooled, and reading was her fatal weakness.

With the help of professionals, I quickly finished turning the soil and got about 30 kilograms of sweet potatoes, but it was completely enough for an experiment.

At this time, there was no intention to eat, so the two sisters cut the sweet potatoes and cut them into diced sweet potatoes slightly larger than corn. They did not need to be peeled, but they must be washed, otherwise there would be mud and sand in the final vermicelli.

One of them was working hard for coal and the other for study. Then they had to use a stone mill to grind the sweet potato diced into slurry, which was easier to produce starch than pestle in the trough. The stone mill in the village was quite heavy, and most women could not push it alone.

There was no choice but to call the two brothers of the Qin family. Digging coal is considered a free life, as long as the task is completed.

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

Pushing mills are also used to utilize the lever principle. A one-foot-long wooden square is embedded on the stone mill. A hole is made at the end, and then the pushing rake is buckled. The pushing rake is more than two meters long. The end is hung on the beam and keeping it level with the ground.

In this way, you can just push forward directly at the end with human power. The stone mill will rotate as soon as you push and pull. The movement is similar to the yangko dance. The movement of the Neo flash bullet in the Matrix actually imitates the push mill of Greater China, uh!

After forty minutes, the sweet potato slurry was finally OK. If there was a crusher, the sweet potato would be OK in at most three minutes, and there was no need to cut the sweet potato into diced in advance. Machine, machine, science and education, the four words "The Four Words of Promoting the Country" are really incisive!

"Dajun, what are you doing now!" Qin Er asked excitedly, nothing happened, because Fang Dajun promised that if the vermicelli matter was done, each household would have at least fifty yuan in income during the Chinese New Year. If it was controlled well, hundreds of yuan would be possible, and this would be a huge sum of money!

And there is another point. Although the remaining powdered slags after filtering cannot be sold for money, they can be used to feed livestock. The powdered slags distributed by each household are not a problem to fatten a pig, which is another few dozen yuan.

Although the villagers have no red potatoes to eat, they can buy nearly a thousand kilograms of rice for more than 100 yuan, which is a luxury!

"Filter!" Fang Dajun said happily.

The division of labor immediately began. Qin Er was responsible for fetching water from the well. Qin Dalai shook the linen and filtered it. Fang Yan was responsible for adding it. He was a patient, so he was responsible for guiding the work.

A wooden frame with the shape of "well" is hung on the crossbeam, and the height is just at Qin Da's elbow. This position is the most labor-saving. A square piece of linen is tied to the four corners of the "well" frame, which becomes a hanging funnel.

Below the funnel is a large jar, which is burnt by soil and supports brick farms. Every household in the village has it. Then the ground sweet potato slurry is poured into the linen funnel, and then the clean water is poured inside.

Qin Dashi grabbed the two corners of the wooden frame and began to shake it. The second sister Fang Yan added clean water to it from time to time. When the water flowing out of the funnel was no longer turbid, the construction was completed.

If the sweet potato slurry in the funnel was just a basketball, but now it is still the size of a football, it is not very shrinking.

"Dajun, why is this starch different from what is sold in the town?" Qin Da asked in confusion as he looked at the things in the linen.

Fang Dajun suddenly became cold and smiled: "The burr is the powdered slag, and the leaking starch is the one that is starch."

"What? You said the water in this tank is starch?" Qin Da opened his mouth, unable to believe it at all.

Qin Er also ran over and shook his hand in the tank for a few times. He didn't feel anything, it was all water. "Da Jun, aren't you joking?"

"I understand!" Fang Yan suddenly exclaimed, "Brother means that these white water will be starch after precipitation, right?"

Fang Dajun smiled and said, "That's right, that's what it means. Now the starch has basically been filtered into the water. When it settles, the bottom layer is starch. The precipitation time will be very long. Find a dustpan to cover it so that the wind will not blow into the sand. It will be almost the same tomorrow morning."

"It will take so long?" Fang Yan was a little surprised.

Fang Dajun said helplessly: "There is no way. If there is a roller machine, you can repeatedly use the water source. However, the clean water used to filter through this method is too much. More than 90% of the large tank is water. If you want to completely settle, it will take about ten hours at the earliest, so you can only wait to make vermicelli tomorrow morning."

One pound of sweet potatoes cannot produce two taels of dried starch, and the remaining eight taels will basically not be consumed. This is the powdered residue.

"Second sister, try feeding the powdered slags to pigs." Fang Dajun suggested that although theoretically, powdered slags can be fed pigs, it depends on whether the pigs love to eat them.

"Well, let's try it now!" Fang Yan said, scooped half a scoop of powder and headed to the pigpen. The three of them followed and took a look.

There is only one pig in the pigpen, which is only eighty or ninety kilograms. It is pitifully thin and has been raised for more than half a year.

"Crash!" As soon as the powdered slag was poured into the trough, the thin pig immediately started to eat fiercely, swaying its tail, and eating very happily.

After a few dozen seconds, the trough had slipped away, and the thin pig kept shaking his ears and shook his tail, whimpering.

"It's done, it can be used to feed pigs!" Fang Dajun said happily. Although starch has been filtered out, the powder residue is also nutritious, so the pig will naturally grow meat faster after eating it.

"Da Jun, you are so powerful!" Qin Er said with some admiration.

But Fang Yan still expressed his opinion, "Of course you can eat this little bit of powdered pork now, but how should you preserve powdered pork when it is made in large quantities? Do you have to dry it? It is not as good as the weather in autumn and winter."

Fang Dajun smiled and said, "No need to be so troublesome. Just keep the powdered residue as kimchi. Scoop a little out every day and mix it with pig grass to feed it. It can be fed for a long time, which is enough to fatten the pig."

"Take it as kimchi?" Fang Yan frowned, obviously not understanding it.

Fang Dajun directly despised: "How did you learn chemistry in junior high school? You can still get into high school. The powdered slag contains water. It can be fermented as long as it is mixed with salt. It can be stored for several months after sealing. Although it is not as big as a jar to completely seal it, there is nothing to do. Even if it tastes a little bit scent, it is probably better for pigs to eat it. 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 get high school?" Fang Yan was very surprised.

Fang Dajun really wanted to say: "Don't be obsessed with me, because I am a legend!"

"Second sister, think about it, it's seven years in high school. Isn't this delaying my time finding a wife? I don't study anymore, so I can find a wife at any time."

"Color! I don't know who I learned bad things from, so I won't tell you anymore. I'll go and have a hot meal." Fang Yan said and ran away.

Fang Dajun smiled and greeted the two brothers of the Qin family bravely. After the vermicelli could make money, he could respond in the production brigade. Now he does not occupy the time, but he has the advantage of the territory and people.
