At noon on the second day, Lao Changjia and his son arrived at Xu He's home carrying a bag.
When more than thirty kilograms of brown sugar was placed in front of Xu He, Xu He also rubbed his hands with some excitement.
To be honest, apart from boiling brown sugar water for his wife in his previous life, he rarely came into contact with this stuff.
Who would have thought that they would rely on this thing to make a fortune and seize the first pot of gold in life?
"Xiaohe, what should we do now?" Old Master Jia and his son looked at Xu He helplessly.
When it comes to this, Xu He is very confident.
He first asked Xu Peng to go home and find a wooden funnel used for making rice wine during the Chinese New Year. Then he pulled a bundle of straw from the stove, cleaned it, and plugged the bottom of the funnel.
After completing this step, he asked Xu Peng to light a fire, pour the brown sugar into the pot and add water to boil.
When the old commander saw this, he said sternly: "Xiaohe, I think you are doing a good job. It seems that you really understand!"
Xu He chuckled: "Of course, uncle, just watch it!"
In fact, the method for extracting white sugar from brown sugar in "Tiangong Kaiwu" is very simple, that is, plug the funnel with straw, then put the boiled sugar syrup into the funnel, and then use diluted yellow mud water to adhere to the impurities in the brown sugar. It’s white sugar.
Here, while Xu He was boiling brown sugar, he asked Lao Jia to go outside and get some yellow mud.
When the brown sugar boiled into a paste, Lao Changjia came back covered in mud. He was holding a tube of yellow mud water in his hand, and he was very excited.
Xu He immediately scooped out the brown sugar paste with a spatula and put it into the funnel. At this time, Xu Peng also came closer to watch this exciting scene.
"Witness the miracle!" Xu He poured the yellow mud water into the funnel with a glowing face.
When Lao Zhang saw this scene, his face was a little distorted. He had just used five kilograms of brown sugar, which was a full two taels of silver. In the blink of an eye, he was submerged in yellow mud water, and his heart... felt a little painful.
I saw the brown sugar paste slowly floating in the funnel due to the buoyancy of the yellow muddy water.
At this moment, time seemed to stand still, and there was no movement at all below the funnel.
Finally, a "tick" sound reached Xu He's ears. Xu He looked down the funnel in surprise. Sure enough, the drop of water that fell into the basin exploded blackly in the basin, forming small black spots.
Xu He secretly clenched his fists. The next second, there was another drop, and then more and more water drops appeared on the straw at the mouth of the funnel.
Lao A slapped his thigh: "I know, this black water is the impurities in the brown sugar, which were taken away by the yellow mud water!"
Xu He stopped pretending and laughed: "Yes, yellow mud water has adsorption properties and can take away brown sugar impurities."
Lao Changjia and his son seemed to have learned some great secret, and they looked excited.
The water level of the yellow muddy water gradually dropped under the gaze of the three people, and finally, there was still a shallow amount left in the funnel.
"Come on, my sugar, no, my money is going to be watered down!" Xu He shouted in his heart.
But after a few minutes, all three people were stunned.
I saw a yellow thing hanging on the straw of the funnel.
"this……"
"what happened?"
"Where's the sugar?"
Xu He was dumbfounded, and so were Lao Jia Zhang and Xu Peng.
The white sugar was promised, the adsorption was promised, but what came out was a yellow lump full of straw powder!
At this moment, Lao Jia was disappointed. He shook his head and sighed: "Xiaohe, this is only two taels of silver. It's just wasted like this. Clean up this stall and feed it to the pigs. I will take the remaining brown sugar back to the city tomorrow." Give it a try!”
"Something's wrong, something's wrong. The so-called "Tiangong Kaiwu", a book on black technology in the late Ming Dynasty, can't be a lie, right? Which link is the problem?" Xu He's forehead was covered with sweat.
"Do I need to filter it a few more times?" Xu He suddenly had an idea.
He quickly fetched a new pot and placed it under the funnel, and poured the newly filtered water into the funnel.
When Lao Jia Chang and his son saw this scene, they also guessed Xu He's intentions, and hope could not help but rise again in their eyes.
But liberal arts students are liberal arts students after all, and they can screw up even the simplest sugar refining in the secrets of getting rich through time travel.
I saw that the sugar paste had obviously shrunk to one-third of its size after secondary filtration, and was still yellow.
Xu Peng dipped his hand into some yellow mud water and put it into his mouth. After a while, he cried and said to Xu He: "Xiao He, let's not try it. The yellow mud soup down there has turned into sweet water!"
Stunned! ! ! ! !
"How confident you were just now, now you're going to die. We're going to embarrass the time traveler."
The three of them had been busy for a long time, and Ms. Xie didn't even have time to cook, so she had to go to Lao Jia's house to cook it and bring it to her third son.
But after working for a long time, I didn't see the sugar. The yellow mud sweet water will be cheaper tomorrow, the second senior brother.
Just when Xu He was about to give up, he suddenly saw charcoal piled in the corner of the kitchen.
These charcoals were from winter. Mrs. Xie was afraid that her son would get cold while studying at night, so she specially bought some for him to keep warm.
At this point, there is still some left, mostly charcoal residue.
Xu He's eyes suddenly lit up. As for the most absorbent thing, yellow mud soup is probably not comparable to charcoal powder. If the yellow mud soup is replaced by charcoal...
Thinking of this, he quickly pulled Xu Peng and asked him to light the fire again.
Seeing that he was still struggling, Lao Jia quickly protected the remaining brown sugar: "Xiaohe, don't bother with it. If white sugar was so easy to make, people would have already used it to make money. How can it be our turn?"
Xu He shook his head: "Uncle, let me try again!"
Seeing that he was determined, Lao Jia had no choice but to take out another two kilograms of brown sugar and hand it to Xu He: "For the last time, uncle can't see you wasting money! If not, I will refund it for you. You can use the money well." read!"
Xu He was helpless. Is this because his reputation points have been used up? Don’t trust me anymore!
It was the same step as before, but this time Xu He put the boiled sugar paste into a basin, added water, took charcoal from the corner, crushed it and sprinkled it into the basin.
The three of them stared at the tub again.
After about half an hour, the eyes of the three of them were sore from staring. Finally, Xu He asked Xie to help find a new bamboo fence, and covered the fence with a piece of gauze.
Here Xu Peng followed Xu He's instructions, lifted the wooden basin, poured the dark water inside into the fence, and then flowed into the wooden basin below.
At this time, the water flowing into the wooden basin below was obviously much clearer, with only a slight yellow color, while the gauze on the fence was full of impurities from charcoal and melted brown sugar.
Looking at the clear yellowish water in the wooden basin below, Old Master A was a little confused about the situation: "Xiaohe, is it successful or not?"
Xu He shook his head and poured the water into the pot again.
Seeing this, Xu Peng ran to light a fire.
As the pot boils, water vapor rises and there is less and less water in the pot.
Suddenly, the old commander exclaimed: "White sugar!"
Xu He heard the words and looked in the direction of his finger. Sure enough, he saw that as the water level in the pot dropped, a layer of white crystal formed around the pot.
Xu He couldn't wait to pick up his chopsticks, scrape off a little bit and put it into his mouth.
At that second, the sweet taste filled my heart.
It’s finally done!
