Chapter 499: Be Senseful

“The squeezed juice is filtered to remove the mixed residue and particles.

Then heat it to remove the water in the juice, which is the step of making sugar juice with brown sugar.

The next step is precipitation and the addition of activated carbon. In this step, you can add an appropriate amount of lime water and let it settle for a period of time.

Filtered and decolorized with activated carbon.

Then it enters the crystallization stage. If it is left to stand slowly, it can form rock sugar.

If you want to make white sugar, you can use the evaporation crystallization method. Place the sugar water in a device and heat it to concentrate the sugar, thereby crystallizing it.

You can also use the centrifugal crystallization method…” Su Ying explained the principle while drawing.

"Centrifugal? What does centrifugal mean?" Li Tai looked confused, and so were the other princes.

"Uh, have you ever used an umbrella?" Su Ying thought for a moment and said.

Everyone nodded.

"Have you ever tried turning the umbrella handle and making water droplets fly off the edge of the umbrella?" Su Ying asked again.

"Oh, this is centrifugal?" Li Tai seemed to understand something.

"That's right, that's centrifugal motion!" Su Ying nodded.

"Sugar water is injected into the rotating body, and during the high-speed rotation, the sugar water is thrown away and splashed, landing on the covered tank and quickly crystallizing.

By heating and drying it, the sugar will fall off the can, which can increase sugar yield and production speed."

Everyone was silent as they listened to Su Ying give a lecture they had never heard before.

"Okay, Fourth Prince, I've told you the principle. You can figure it out yourself and see how to build a production line to produce sugar in batches." Su Ying looked at you with optimism.

"Master Xiao Su, what we just learned was how to make rock sugar, and white sugar was made as a by-product. The new process you mentioned is the process for making white sugar, right?" Li Tai sorted out his thoughts and said.

"Smart!" Su Ying smiled. It was easy to teach a top student.

"Why white sugar? Isn't there a quick way to make rock sugar?" Li Tai asked.

"Well, because white sugar is much more useful! You can re-melt the white sugar, purify it, recrystallize it, and get rock sugar.

You can also use the decolorized syrup and let it stand until it crystallizes." Su Ying replied.

"Aren't white sugar and rock sugar both sugar? Why is white sugar more useful?" Li Tai asked.

"White sugar has small granules and dissolves easily, so it can be used as a sweetener for cakes and other candies. Rock sugar has large granules and takes time and effort to dissolve."

Su Ying said some obvious things, but didn't mention the strategic use.

Li Chengqian looked nervous, fearing that Su Ying would reveal the purpose of the explosives. Fortunately, fortunately, Master Su knew his limits.

"What other candies can it be made into?" Li Tai became even more interested. "What else can it be made into?"

"Well, for example, the hawthorn cake and fruit leather we made yesterday, if we have milk, we can also make milk candy.

Anyway, Your Highness, if you think about it slowly, you will find that there are many more candies that can be made. The profit from sugar alone is not inferior to that from salt."

Su Ying suddenly thought of something good, but she didn't want to tell it in public.

Several princes looked at Li Tai with envy, knowing that this guy would not do anything without profit. Giving such a valuable gift to Lord Su, the reward must be thousands of times greater.

Li Tai was very proud when he heard this.

"Um, Lord Su, how much human or animal power is needed to roll the sugarcane with two rollers?" Li Ke was puzzled.

"No need for that, just use water power!" Su Ying said.

"Hydraulic power? What does that mean?" Li Ke asked. "Is it the same as a water mill?"

"Yes! The roller shaft is connected to the horizontal water wheel, which uses the water flow to generate power to drive the roller to rotate." Su Ying replied with a smile.

Water mills appeared in the Jin Dynasty. The power came from a horizontal water wheel. Water mills could even be made into complex structures. One water wheel could drive several mills to rotate, which was called a water-driven linked mill.

"Why did Third Brother say that?" Li Tai was a little unhappy. He had thought of it a long time ago, but now that Li Ke had exposed it, the mystery was gone.

Su Ying advised, "Don't worry, Your Highness. The most critical part of this process is the centrifugal equipment. Do you want the Third Prince to join us so you can discuss it together?"

This equipment will handle feeding, rotating, crystallizing, drying, and discharging simultaneously. With more people, more power, we hope to have it completed before the sugarcane harvest at the end of the year."

Li Tai looked at Li Ke and was not very happy. He thought he could also figure it out by finding a team of people himself.

"Your Highness, we have a variety of new candies to develop. This is a whole industry chain, selling them to the Western Regions, the Arab Empire, and India. Even salt can't match their profits!"

Su Ying hinted secretly.

"Okay! Third brother, you will join us. However, you also have to pay a tuition fee!" Li Tai didn't want to pay so much tuition fee in vain.

"Okay! Fourth brother, what you said makes sense. I will give you twenty pieces of Shu brocade when I get back!" Li Ke said happily.

"Wrong! It's forty pieces of Shu brocade, for Lord Su!" Li Tai said mischievously.

"Fourth Prince, that's enough!" Su Ying quickly declined.

"Master Xiao Su, don't say anything!" Li Tai said tyrannically, "If my third brother sincerely wishes to join, just like me, forty pieces of Shu brocade will be given to Master Xiao Su!"

"Okay!" Li Ke agreed without hesitation.

"Tsk tsk!" Li You was shocked. "I can't take it out!"

Su Ying felt that it was too hot to handle, but if she didn't accept it, Li Tai would think about it.

Even though they are only eleven or twelve years old, the children of the Tian family mature earlier than their peers. The relationship here is very subtle.

"Sister! The mints are ready!" Xiaotao and Atang, who were waiting outside, shouted.

The third batch of mint candies was brought in, already frozen solid, with a minty, green and pink color, looking beautiful and exquisite.

There is a rough mark on the template. Break it hard along the long mark and a large piece of mint candy will be broken off.

Then break it along the short mark to make small cubes half an inch square, and each person can taste one.

It tastes sweet at first, and then a cool feeling comes. The sugar juice goes down the throat and into the stomach, and the chest and throat feel cool.

Su Ying divided the mint candies into several portions and put one portion in a white porcelain jar for each of the princes and Du He.

He also packed one copy each for the emperor, the empress, and the two princesses, and gave the rest to his two younger sisters.

"Gurgle..." Someone is hungry.

"The palace banquet will last for another hour!" Li Chengqian looked at Su Ying, meaning to lay the foundation here first.

After working for a while, the little food I had eaten in the morning was already digested.

"It's too late to cook right now. Do you want to have fried rice with egg?" Su Ying scratched her head.

"Okay! What Lord Su makes must be delicious!" Li Tai sat down, exhausted.

Ah Hua lit a fire, and Su Ying made fried rice with yesterday's leftover rice and chopped some pickled mustard greens.

Fry the cold rice until the rice grains jump in the pan, then push them aside. Add lard to the hot pan, add eggs, and stir with a spatula until they are broken into crumbs.

Add chopped preserved vegetables and stir-fry for a few times, then mix with rice and stir-fry.

Sprinkle with salt, pour a little soy sauce, sprinkle with chopped green onions, turn it over a few times and serve.

The princes gathered around the stove. They had never seen anything cooked this way before. It looked sloppy, but it smelled delicious.

The rice grains are crystal clear, slightly burnt, and a little crusty.

"I want two bowls!" Li Tai shouted.

"Uh, Fourth Prince, there's not much rice, only enough for one bowl per person!" Su Ying was embarrassed.

"Okay then!" Li Tai said embarrassedly.

Take the egg fried rice and take a bite. The flavors and textures of rice grains, eggs, and preserved vegetables are mixed together, with the bean aroma of soy sauce.

The princes were astonished and ate the rice in big mouthfuls, without any of the palace reserve. They were a group of half-grown children, eating voraciously.

"Hurry up!" One by one, they were choking and hiccuping, beating their chests.

Su Ying brought sour radish soup, and the princes drank it and finally they felt better.

"Alas, what kind of palace banquet is this? It's not as delicious as Lord Su's fried rice!" Li Tai sighed.
