Chapter 39 On How to Make Sugar from Thatch
"Your Highness, are you saying that you need a large amount of sugar cane?"

The Shaofu supervisor was called over, and when he heard Li Ming's request, he couldn't help but pay attention.

Sugarcane, called Zhe in ancient times, was called sugarcane in the Six Dynasties. It originated in Southeast Asia and was probably introduced to southern China in ancient times. Now it is very common in China.

It's just that although this thing is common, it's not so easy to get it, especially this is Chang'an, winter.

That's even more difficult.

But after concentrating for a moment, the Shaofu supervisor still nodded.

"Your Highness, give me 30 days, and I should be able to get a lot of sugar cane."

The words spoke with affirmation.

"30 days?"

Li Ming frowned slightly.

Somewhat disappointed.

Still nodding.

After all, this is ancient times, and it would be nice to be able to obtain sugar cane.

It is not so easy to get nature immediately.

30 days is not too much to wait.

Of course, the more important thing is that if you just have a taste, he still has a way to replace it.

So after nodding, he pondered for a moment before speaking again.

"For sugarcane, try to collect as much as possible, and it's best to ensure that you can continue to obtain it. In addition, you have to order that the Shaofu purchase the white grass, one copper coin per catty, and there is no limit. The earth dragon temporarily stops the purchase."

Now that the acquisition of Earth Dragon is already extremely large, there is no need to continue the acquisition, otherwise the soil will suffer great damage.

As for Imperatae, of course it is a substitute for sugar cane.

Since sugar cane cannot be obtained in a short time.

In this era, there will be no sweet potatoes and beets.

After all, sweet potatoes are still grown in the Americas, and beets are grown in Europe.

Then you can only use white grass instead.

The so-called Imperatae is thatch root, which also contains a lot of sugar.

Although it is too extravagant to make sugar with imperata.

The manpower and material resources needed are somewhat outweighed by the gains.

But this is not modern, it is ancient.

The value of sugar is far higher than the manpower and material resources paid.

Of course there is no problem.

Although the Shaofu supervisor was puzzled in his heart, with previous experience, he would not have any meaning, so he quickly took action.

The purchase of Baimao is only a penny per catty, and he can buy [-] catties with a shake of salt, so he doesn't care too much at all.

Soon, Li Ming's order was conveyed in the Shaofu.

Hearing that the acquisition of Earth Dragon had stopped, many people were a little rioted.

But when they heard that in exchange for the acquisition of Baimao, the commotion stopped immediately.

Although the price of white grass is cheaper than that of earth dragon, and it only costs one penny per catty, it is actually much easier than that of earth dragon. Don't be too simple.

In fact, the money that can be harvested on this day will only be more.

Soon, one after another figure impatiently went to the wild to get the imperata.

On that day alone, Shaofu purchased nearly 100 catties of Imperatae.

And this is just the beginning, and it is expected that the next gains will only be greater.

But compared to the earth dragon, this thing doesn't need to worry about damaging the soil at all.

Some even endanger farmland.

Both rhizomes and seeds of Imperata can reproduce.The spread is very fast. Generally, the rhizomes germinate and unearth from late March to early April, and the ears will bloom in May-June.When mature, it falls off with soft hairs from the spikelet stalk, and is scattered with the wind. It can germinate after landing, and the seedlings born in that year can form underground rhizomes.Because of its rapid occurrence, high density, rapid growth, and strong competitiveness, it competes with the land for water, fertilizer, and glory; especially its huge root system has a strong ability to consume water and fertilizer.

If you buy these, you can also manage them.

Of course this is just extra.

After obtaining the initial [-]-jin Imperatae, he started his mighty sugar-making process.

There is not much difference between imperata and cane sugar in essence.

After washing, directly add water to crush, then filter.

Unlike sugar cane, the sugar content of coriander is too low, so lime milk needs to be added.

Then boil again, add lime milk again.

Subsequent to precipitation.

Precipitation removes non-sugar impurities.

Then concentrate.

That is to boil.

Due to the extremely low sugar content of coriander.

The sugar liquid left over from this cooking can be said to be pitifully small.

In the small courtyard, several cauldrons were steaming.

One after another figure is busy in the rapid.

And Li Ming is also busy.

What he wants to make is naturally not brown sugar, but white sugar, or rock sugar.

In the original trajectory, the initial appearance of Baitang and Bingtang also got the events of his Ninth Brother's reign, and naturally there is no such thing now.

Whether it is white sugar or rock sugar, there is a big problem in it, that is, the problem of crystallization.

Rock candy is okay.

The crystallization method is as long as the sugar liquid out of the pot is put into the pan and placed on the soil pit. The temperature in the pan is kept at about 90°C on the same day, and then the temperature is lowered by 10°C every day until the seventh day, and rock sugar will naturally gradually form.

Sugar, on the other hand, is more complicated.

Requires a centrifuge, and crystallization.

At this time, Li Ming was busy making crystals by local methods.

Fortunately, there is relevant information on the local method of making sugar, and he only needs to carry it out step by step.

As for the steps, it is also very simple.

Pour a small cup of water in a saucepan and heat the saucepan over low heat.Slowly inject two cups of sucrose.When the aqueous solution of sugar is saturated and boiling, pour the liquid into a cup, then place the cup in a cool place for several days, and crystals will form.If there are vertical lines in solution, crystals will grow in a "chandelier" shape.

Once the crystals are formed, the next step is the centrifuge.

This thing is relatively complicated, so don't even think about high-end ones, unless the system signs in.

But it is obvious that it is basically impossible for a system with only one level to sign in.

But you can also directly make a manual, small one.

Although it is almost impossible to produce a large amount of white sugar by relying on this, a small part can be done.

Soon, several hand-operated centrifuges were successfully produced by him.

At this moment, the mother liquor and crystals can naturally be separated.

Naturally, it was impossible for Li Ming to do this kind of physical work, and the task was entrusted to everyone in the Shaofu.

Accompanied by vigorous shaking one by one.

The crystals gradually separated.

When the fifth day came.

In front of Li Ming's eyes, there was already a small pile.

Its particles are crystalline, uniform, and white in color. In this era, it is almost like a work of art.

Gently pick up some and put it in your mouth.

Immediately, a pure sweet smell spread to the mouth, making Li Ming's eyes brighten up.

Obviously, at this moment, he succeeded.

Although the white granulated sugar is not as uniform as he imagined, the snow-white color and pure sweetness undoubtedly represent success.

Although there is not even a tael of white sugar in front of one hundred catties of white grass, plus the loss due to mistakes in the middle, it is still a success.
