Be a master through ancient times

Chapter 452 Adsorption Separation Experiment



"My lord, it's because the old man didn't take good care of the crops, so they were trampled by those beasts, please punish me!"

In the farm, an old man with gray hair stood below, his eyes were full of tears, his face was full of guilt and uneasiness, and his rough hands were shaking constantly.He is a tenant in this school field, and he is considered a farmer in this farm.

"Don't be too nervous, the old man. I don't mean to blame you. Please sit down first." Chu Ci said immediately, this is a natural disaster, how can people be blamed?

"Thank you sir!"

The old man wiped away his tears and sat down on the stool carefully.

"What do you call the old man? How long have you lived here?"

"The old man's surname is Chen, and his name is Chen San. He has lived here since he was a child, and my parents used to be tenants here." Old man Chen replied tremblingly, fearing that Chu Ci's next sentence would make him leave the place where he had lived all his life.

"Chen Weng looked at him since he was a child, so he must have a lot of experience. No wonder Xuetian's account books have been handed over in the past few years, and they are always getting better every year." Seeing that he was nervous, Chu Ci deliberately praised him to relax him.

Old man Chen smiled shyly. He has been farming all his life and dealing with crops all his life. Among other things, he thinks he is somewhat useful in this.

However, thinking of the fields destroyed by wild boars last night, a guilty expression appeared on his face again.You've heard the roar of the tiger, so why don't you know how to be more vigilant?well!

"I don't know what is the best plant in our farm?" Chu Ci saw his mood and deliberately changed the subject.

"My lord, the best thing we grow here is rice. The rice outside is usually harvested once a year, but in our Southern Fujian Province, it can be harvested twice a year!" Speaking of the area he is good at, old man Chen came interest.

Chuci also knows that they cook twice a year.This is not to say that one batch of rice can be harvested twice, but that the time difference is used to sow twice a year, which is called early rice and late rice.In the rice fields ravaged by wild boars, early rice is grown.

"...I hate those damned wild boars. Right now, the rice is full of grout, but they have ruined it. It stands to reason that in another forty days, the rice can be harvested!"

"There is no way around this. Now we can only pull them out and re-sow them. At best, the earlier they are planted, the earlier they can be harvested, and you can also rest early in the winter." Chu Ci comforted.

"That's not possible," Old Man Chen waved his hands repeatedly, "We don't want to have a winter break here. After the late rice is harvested, we have to harvest sugarcane. Fortunately, those animals didn't go to the sugarcane field, otherwise they really broke into it." disaster."

sugar cane?Chu Ci remembered that last year, it seemed that the people below gave him some New Year's gifts, the kind chopped up one by one, and everyone in the house loved it.And Chu Ci himself was not used to eating it, he just ate it for a while, and then stopped eating.

"Based on what Chen Weng said, this sugarcane seems to be more important than rice?" Chu Ci felt a little strange. In his opinion, sugarcane is just a kind of fruit, and it is still the kind that is extremely laborious.

"That's right. Rice is a rare thing in some places, but it's not so much in our place. Everyone has grown it at home, and the selling price has never risen. Let's transport it out, and I'm afraid that the sea will rot. But the sugarcane The made brown sugar is better sold outside.” Their farm sold a lot last year, and the selling price almost caught up with the sale of early and late rice.

"Brown sugar was originally made of sugar cane?" Chu Ci suddenly realized that he knew both of these things, but he had never tried to understand them. Hearing him now, he understood why sugar cane was more important. It was really because of the price of sugar Much more expensive than grain prices.

He still remembers that year when he returned home during the Chinese New Year, he made a bowl of brown sugar water for each of the elderly people sitting in the yard, and they were reluctant to drink it by themselves.Afterwards, when the elders in the village mentioned Chuci, they all said that Chu Xiucai was a good person, and they would reprimand him when they met someone who said something sour.All this is not the charm of brown sugar water.

"Chen Weng, can you take me to the sugarcane field?" Chu Ci became interested. He had seen sugarcane, but he had never seen sugarcane growing in the field.

Old man Chen immediately got up and prepared to lead the way. He thought that Chu Ci was worried, and he had to see it with his own eyes.

A few people left the farm and walked towards a small road. After walking for about a quarter of an hour, rows of sugar cane appeared in front of them.These sugarcanes are growing well, about thigh high, and the leaves on the top are stretched out, looking vibrant.Chu Ci privately felt that these ungrown sugarcane seedlings looked quite like sorghum in the north.

"We'll be fertilizing in a short time. If you want sugarcane to be sweet, you need to be fertilized. Every year, the sugarcane grown on our farm is the sweetest, and the squeezed sugar is also the best." Old man Chen stroked the field with one hand. sugarcane seedlings, said with a little pride.

"Where are these boiled sugars sold every year?"

"Both the north and the south. It doesn't work if it's too dry or too wet, otherwise there will be less sugar." Old man Chen obviously summed up his experience in growing sugarcane after experimenting with some methods.

This morning, Chu Ci stood in the sugarcane field and listened to Old Man Chen's sugarcane scriptures. At noon, Old Man Chen warmly invited Chu Ci and the others to his house for an authentic farm meal.

Although I didn't see any wild boars during this trip, it was worth learning something.Thinking of this, Chu Ci felt much better after being corrupted by the wild boar.

At night, Chu Ci had dinner at home.A group of people gathered around the table, eating delicious food prepared by Zhang Hu.It turned out that Zhang Hu's cooking skills were not very good, but after making fish balls, he seemed to have lightened up a certain aspect of his skills and became interested in cooking.

Chu Ci specially paid him to go to the restaurant to learn from a teacher, and the shopkeepers were also happy to deal with Chu Ci, and asked the cooks to teach them well.Of course, this is limited to some dishes that do not involve secret recipes.

Like today's braised pork, there is no secret recipe. Zhang Hu has already mastered the craftsmanship. The meat is ruddy in color, soft and delicious to eat, and the sweetness is moderate. The girls also had a great time eating.

After the meal, when a group of people were sitting in the living room chatting after a walk, Chu Ci talked about what he had seen and heard today, and when he heard that planting sugarcane had so much attention, a group of children expressed their surprise.When I heard that sugar cane can also make brown sugar, I was even more incredible.

Just when everyone was thinking about how to make brown sugar, Chu Xiaoyuan suddenly asked: "Uncle, but the juice of sugarcane is not red, why is brown sugar boiled? Why not frosted sugar?"

Frosted sugar is white sugar, which is something only rich people can afford, and it is much more expensive than brown sugar.If Steward Xu hadn't bought some back, Zhang Hu wouldn't have bought such expensive candy according to his temperament.

Chu Ci was at a loss for words for a while, because he didn't quite know how sugarcane was made into brown sugar.As for how the white sugar came from, this Chuci knows. He participated in the provincial chemistry competition in junior high school. The teacher in charge of the training taught them some high school chemistry knowledge in advance, including the adsorption separation experiment. Brown sugar to white sugar.

He recalled what the teacher said at the time, that it should use the principle of activated carbon to remove impurities with the help of the "van der Waals attraction" between molecules, that is, the mutual adsorption.

In this way, as long as the brown sugar is turned into white sugar, the selling price is enough to offset the loss of last night!

The more he thought about it, the more excited he became. In the morning, he was worried that the destruction of the school field would reduce the output. Who knew that the solution would be solved in the evening!
