After the sugar water became clear, Suren did not continue to stir, let the sugar water settle, and then strained the charcoal out.

A bucket of sugar water is about 20 liters, and if you want to turn sugar into sugar, you need to heat it to evaporate the water in the sugar water, and when the water is reduced to a certain level, there will be crystals.

Su Lun found an iron pot, poured sugar water into it, and then lit a fire to boil slowly, as the temperature rose, 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, but fortunately, there was no problem with his method of boiling sugar, and after about an hour, 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 his senses, and after the white sugar appeared, the speed of sugar production began to accelerate, the flames continued to burn, the sugar water in the iron pot was boiling, and more and more white crystals appeared in the iron pot.

The barbarian warrior next to him smashed his mouth, "Head, how can this sugar water freeze inside when it boils?"

"Stupid, don't talk if you don't know!" Su Lun glared at him.

With the passage of time, the sugar water in the iron pot became less and less, and the condensed sugar in it also increased, and finally after continuing to boil for a while, the white sugar in it was no longer condensed, and Su Lun filtered out the white sugar inside.

The rest of the sugar water is actually waste honey, although it contains a lot of sugar, but due to technical reasons, it cannot be extracted at all.

Waste honey was high in sugar, but it was not possible to extract the sugar in it due to technical reasons, and finally some people discovered that this waste honey could be used to make wine, and then a new type of rum was born.

The waste honey was filtered out with cotton yarn, and a bunch of white particles such as sand and snow appeared in the iron pot, which was white sugar.

The barbarians next to them didn't know what the principle was, and looked at the white sugar in amazement.

"Taste it. Su Lun hugged his arms, and raised his chin lightly. It's just that his style must have been in vain, and these barbarians in the wilderness had never heard of white sugar before.

"It looks like ice crystals. A savage stretched out his finger, dipped a little into his mouth, and then said in surprise, "Sweet, this is sugar?"

"Nonsense, isn't sugar boiled out of sugar water?" Su Lun tapped the barbarian's head with a spoon.

"Head, then we'll have candy to eat later?" said the barbarians excitedly.

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

Su Lun collected these white sugars, and then weighed them, these white sugars totaled a little more than three catties, and the boiled sugar water had twenty liters, that is, about forty catties, a total of three catties of white sugar, Su Lun was still very satisfied with this sugar rate.

Using this relatively primitive method to make white sugar, it is already too much to have three catties of sugar, as far as Su Lun knows, the sugar production process in this era only has a sugar yield of 5 to 7 percent, and the sugar produced is still brown sugar.

After determining the method of making white sugar, he then juiced all the remaining beetroots, and then made white sugar, and finally got a total of fifteen catties of white sugar, which was dried and then knocked into a sealed clay 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 technological crafts and successfully opened the technology column. ”

"Data updating... Update complete!"

Just after he sealed the sugar and kept it, the sound of the system sounded in his ears.

Opening the system interface, Su Lun soon saw a science and technology bar in the town interface, clicked on the science and technology column, and saw that at this time, there were already three skills in the science and technology column: iron smelting, farming, and sugar making, and under the three skills, all the steps and points of this skill were clearly marked in detail.

Following these production steps, it is possible to set up a workshop.

Seeing this situation, Suren directly followed the steps given above to build a workshop, the sugar workshop requires about a thousand square meters of space, so that an important workshop can only be built in the town, Suren carved out a vacant land near his lord's castle, and then commanded the slaves to build it.

The sugar workshop did not have too complicated machinery, and it was not difficult to build, so Suren commanded the slaves to build the workshop on the one hand, and sent a large number of people to collect beetroot in the wilderness on the other hand, and before the beetroot in the territory was harvested, the raw materials needed for this sugar workshop could only be found in the wilderness.

Fortunately, the wilderness is large enough, and although there are not many places where beetroot grows, the amount of beetroot in the warehouse increases at a rate visible to the naked eye every day.

The construction of the sugar mill was very fast, and it took two days to complete the construction of a workshop.

[Sugar Workshop: This is a simple handicraft workshop, which can make various sugars such as white sugar and rock sugar. Sugar quality +1, sugar yield +1】

Because the sugar process is not complicated and can easily leak if left unchecked, Suren split these processes, each person was responsible for only one of them, and the most critical process was the removal of impurities with charcoal, and Suren selected two of his slaves to operate with a hundred loyalty.

And this process is also carried out independently in one room, and after the impurities are removed, the sugar water will be sent to another workshop for processing.

In addition to these, Suren added a wall outside the sugar factory, except for the workers of the sugar factory, no one was allowed to approach at all, and outside the sugar factory, Su Lun also arranged four barbarian warriors, who would be responsible for the safety of the sugar factory.

Although there are no outsiders in his territory now, but after he takes out the white sugar and sells it, his territory will soon be known by those who are interested, the interest of white sugar is not low, no, it should be said that it is very high, and a pound of white sugar can easily be sold for hundreds of jinnars in Carthusian City.

According to the sugar workshop produces 500 catties per month, Su Lun will get tens of thousands of gold nar profits just every month, which is comparable to the tax revenue of some small towns for a year, of course, this is only the best situation, in fact, when Su Lun sells a large amount of white sugar, the price of white sugar will definitely decrease, after all, scarce is expensive.
