After the sugar water became clear, Suellen did not continue to stir, let the sugar water precipitate, and then filtered out the charcoal.

There are about 20 liters of sugar water in a bucket. If you want to turn sugar water into sugar, you need to heat it to evaporate the water in the sugar water. When the water is reduced to a certain extent, there will be precipitated crystals.

Su Lun found an iron pot, poured the sugar water into it, and then ignited it to cook slowly. As the temperature increased, the water in the sugar water began to evaporate.

The process of boiling sugar was very slow. Su Lun felt bored after watching it for a while. Fortunately, there was no problem with his method of boiling sugar. About an hour later, some white granular materials began to appear at the bottom of the iron pot.

After seeing those white granular substances, Su Lun immediately came to the spirit. After white sugar appeared again, the speed of sugar production began to accelerate, the flame continued to bake, the sugar water in the iron pot rolled, and more and more white crystals appeared in the iron pot.

The barbarian warrior next to him smashed his mouth, "head, how can the sugar water freeze when it's boiling?"

"Fool, don't talk if you don't know!" sullen glared at him.

With the passage of time, there was less and less sugar in the iron pot, and there was more and more condensed sugar in it. Finally, after boiling for a while, Su Lun filtered out the white sugar.

The remaining sugar water is actually waste honey. Although it contains a lot of sugar, it can not be extracted for technical reasons.

The sugar content of waste honey is very high, but because of technology, it is impossible to extract the sugar from it. Finally, some people found that these waste honey can be used to make wine, and then a new rum was born.

Filter the waste honey with cotton yarn, and a pile of white particles such as sand and snow appear in the iron pot. It is white granulated sugar.

The barbarians nearby didn't know what it was, and looked at the white sugar in surprise.

"Try it." Su Lun held his arm and raised his chin. But his style must have been in vain. These savages in the wilderness have never heard of sugar before.

"It looks like ice crystal." a barbarian put out his finger, dipped it in the mouth, and then said in surprise, "sweet, is this sugar?"

"Nonsense, what is not sugar boiled out of sugar water?" Suellen knocked on the barbarian's head with a spoon.

"Boss, we'll have sugar in the future?" the barbarians said excitedly.

"Eat, eat, know to eat, these are commodities used for trading!" Su Lun grabbed a handful of white sugar and looked at it in his hand. Compared with the white sugar he ate in his previous life, the color of these white sugar in front of him is slightly yellow, which should be that the filtering effect of filtering charcoal is not so strong. But even so, the quality of these white sugars is very good.

Su Lun collected the sugar and weighed it. The sugar was a little more than three kilograms. The boiled sugar water was 20 liters, that is, about 40 kilograms. Su Lun was very satisfied with the sugar yield.

Using this relatively primitive method to make white sugar, it is enough to have three kilograms of sugar. As Su Lun knows, the sugar production rate of sugar making technology in this era is only 5% to 7%, and the sugar is brown sugar.

Su Lun used one-fifth of the beetroot he brought back this time. After determining the method of making white sugar, he squeezed all the remaining beetroot, and then made white sugar. Finally, he got a total of 15 kg of white sugar. After drying the 15 kg of white sugar, he bumped it into a sealed pottery pot for preservation.

"Ding, congratulations to the host. You have successfully made white sugar and obtained the sugar making process."

"Congratulations to the host, you have successfully obtained three technologies and successfully opened the science and technology column."

"Data update in progress... Update completed!"

Just after he sealed the sugar, a systematic prompt sounded in his ear.

Opening the system interface, Su Lun soon saw a science and technology column in the town interface. Click the science and technology column. At this time, there are three skills of iron smelting, farming and sugar making in the science and technology column. Under the three skills, all steps and key points of this skill are clearly marked in detail.

According to these production steps, a workshop can be established.

Seeing this situation, Su Lun directly built the workshop according to the steps given above. The sugar workshop needs about 1000 square meters of space. Such an important workshop can only be built in the town. Su Lun delimited an open space near his Lord's castle, and then commanded the slaves to build it.

The sugar workshop does not have too complex machinery, and the construction difficulty is not high. While Su Lun commanded slaves to build the workshop, he sent a large number of people to collect Beetroots in the wilderness. Before the Beetroots in the territory were harvested, the raw materials needed by the sugar workshop can only be found in the wilderness.

Fortunately, the scope of the wilderness is large enough. Although there are not many places where beet roots grow, the number of beet roots in the warehouse increases with the naked eye every day.

The construction of sugar workshop was very fast. It took two days to build a workshop.

[sugar workshop: This is a simple manual workshop, which can make white sugar, rock sugar and other sugars. Sugar quality + 1, sugar yield + 1]

Because the sugar making process is not complex, if it is not controlled, it will be easy to leak. Sulun split these processes. Everyone is only responsible for one of them, and the most important thing is to remove impurities with charcoal. Sulun selected two of his slaves who are 100 loyal to operate.

Moreover, this process is also carried out independently in one room. After removing impurities, the sugar water will be sent to another workshop for processing.

In addition to these, Su Lun added a separation wall outside the sugar workshop. Except for the workers in the sugar workshop, others are not allowed to approach. At the same time, outside the sugar workshop, Su Lun also arranged four barbarian warriors, who will be responsible for the safety of the sugar workshop.

Although there are no outsiders in his territory, after he takes out the white sugar for sale, his territory will soon be known by those who are interested. The benefits of white sugar are not low. No, it should be said that it is very high. A kilogram of white sugar can easily sell for hundreds of ginals in kart city.

According to the production of 500 kg per month in the sugar workshop, sulun will get tens of thousands of ginals of profits per month alone, which is comparable to the one-year tax revenue of some small cities. Of course, this is only the best situation. In fact, when sulun sells a large amount of white sugar, the price of white sugar will certainly decrease. After all, scarcity is more expensive.
