Playing intrigue is worse than engaging in infrastructure

"But there's no need to be too anxious about this matter." Song Qingyuan added suddenly before parting.

Soda ash will not come in handy until making soap, and he hasn't even started pressing soybean oil yet.

"Anyway, those people are idle, so it's better to get some more first." Lian Ti waved his hand and said indifferently.

There is a point in even saying this.Every year in winter, most of the production activities in Mobei also come to a standstill.

Apart from the necessary daily training, those soldiers really have nothing to do.

In addition to making soap, the foundation of many industries is also inseparable from alkali, and it is better to prepare more.

When Song Qingyuan came here, he stopped refuting.

Early in the morning of the second day, Song Qingyuan's subordinates divided into groups and began to get busy.

The production of soybean oil can be roughly divided into pressing method and boiling method.

Considering the efficiency of production and the fuel demand of the boiling method, Song Qingyuan finally chose the pressing method.

The water cooking method can be directly taught to the common people in the future. If there are poor families who cannot afford animal fat, soybean oil can also be used instead.

The principle of oil press is not bad.Song Qingyuan carefully recalled the ancient books he had read before, and drew a three-dimensional diagram of the wedge oil press on the paper.

The oil press is mainly composed of three parts.The first is a base composed of four pieces of wood and a bottom plate, which plays a fixed role.

And the most important thing is the part placed on the base.

This part is made from a stout log.

The middle of the log needs to be hollowed out, one end is used to place the prepared "bean cake", and the other end is opened on the side to place "mujin."

Mujin is a piece of wedge-shaped wood.When the oil is squeezed, they are nailed into the log one by one, so that the bean cake on the other side can be fully squeezed out of the oil.

The last part is a long wooden stake.It is hung on the top of the oil press with a rope, and it is responsible for hitting the bean cake according to the inertia when the oil is pressed, so that the oil in the soybean is fully squeezed out.

In order to let the carpenters fully understand, Song Qingyuan deliberately drew a three-dimensional diagram of the oil press.

But when he showed it to the carpenters, it took a lot of effort to explain the structure of this huge monster to the carpenters.

Song Qingyuan spoke dryly. Just as he was about to sit down and have a sip of tea, he heard one of the craftsmen hesitantly ask: "Your Highness, according to what you said, this should be an oil extraction machine, but the oil extracted Where is it coming from again?"

He actually forgot the most important part.

Song Qingyuan clicked his tongue, quickly picked up the pen, and filled in an oil outlet on the drawing.

After confirming that there were no other problems with the oil press, the craftsmen left the palace with such novel blueprints.

Before coming to the royal court, Song Qingyuan specially asked Lian Ti to designate a place outside the royal city for them to build a workplace for the carpenters.

After the school opens next year, it can also be used as a practice area for students.

The craftsmen here are still making the first oil press machine in Mobei in an orderly manner. In the barracks over there, the soldiers have already dug several truckloads of alkaline soil and are waiting for Song Qingyuan's further arrangements.

It is said to be a military camp, but it actually covers an area similar to that of a large Zhuangzi.

Anyway, according to Song Qingyuan's observation, it should be two or three times larger than the Zhuangzi he bought in Huijing.Only his Zhuangzi hidden in the deep mountains in Yanyun can barely compete with it.

A quarter of an hour later, Song Qingyuan finally arrived at the place where the alkaline soil was kept.

The piles in the warehouse are all soda ash that they have filtered and purified according to Professor Song Qingyuan's method. It is not difficult to make caustic soda from soda ash. The easiest way is to make soda by causticization.

But this method requires a good grasp of the ratio, so Song Qingyuan decided to carry out this step under his own supervision.

"Your Highness, these are the things you asked the soldiers to prepare. Can you see what is missing?" A man wearing a leather hat stood by the newly built stove and said to Song Qingyuan.

Next to him were two large barrels.

This person is the steward Song Qingyuan asked Lian Ti to come to assist him in his work, responsible for contacting the officers and soldiers of the army for him, so as not to get too involved with the army and bring unnecessary troubles to Lian Ti and himself.

Song Qingyuan looked around, and after confirming that there was no problem, he ordered someone to add a corresponding proportion of water to the slaked lime and soda ash to make a lime slurry and soda ash solution.

Immediately afterwards, they were poured into a cauldron and started heating.

As the temperature gradually increased, a pot of gray milk gradually appeared on the stove.

"Continue stirring until it boils." Song Qingyuan glanced at the white paste in the pot, and ordered the soldiers.

After the white slurry boiled, under Song Qingyuan's command, the soldiers put it aside to settle.

The supernatant obtained after the precipitation is heated again to obtain caustic soda.

The sky above the courtyard specially set aside for making caustic soda was gradually shrouded in a large amount of steam.

"Your Highness, is the thing in the pot the so-called caustic soda?" The steward pointed to the white crystals in the pot and asked Song Qingyuan.

Seeing that he was about to reach out to touch him, Song Qingyuan quickly reached out and grabbed him.

"Caustic soda is highly corrosive, so don't touch it with your hands."

After finishing speaking, he did not forget to emphasize the precautions to the soldiers in charge of making caustic soda again.

In just one afternoon, they produced a lot of caustic soda.

Song Qingyuan looked at the caustic soda in a small ceramic urn, and couldn't help feeling a little excited.

This is the foundation of many industries!

After explaining some production details to the soldier in charge of making caustic soda, Song Qingyuan returned to the carpenter's workshop.

Looking at the huge machine in front of him that was no different from the drawings, he once again let out a long sigh of relief.

"But it's finished?" Song Qingyuan asked.

The craftsman on the side responded with a smile, "Just wait for the tung oil on it to dry!"

Song Qingyuan nodded, checked the internal structure, and after confirming that there was no problem, he ordered them: "When it is completely dry, send it to the military camp in the east of the city. There is a special manager in charge of this in the camp. Just find him."

According to this progress, his soap workshop can start in four or five days.

When his subordinates reported to Song Qingyuan that the oil press was ready, he was playing a game of throwing and catching with Daju in the hall.

A few days ago, Daju lived in the beast garden in the royal palace, and Song Qingyuan didn't bother to visit him because he was busy with other things, so the other buildings in the beast garden were ruined and most of them were damaged.

Song Qingyuan had no choice but to have someone pick it up.

Hearing that the oil press had been delivered to the barracks, he handed the ball in his hand to Jiang Duo, and left the palace without looking back under Daju's coquettish persuasion.

In the barracks, many soldiers were surrounding the oil press, looking at the huge monster curiously, and some bold ones even touched it.

"His Royal Highness is coming!" Suddenly someone whispered at the door.

The crowd dispersed quickly, making way for Song Qingyuan.

Song Qingyuan walked in, looked at the curious soldiers in their eyes, and asked gently, "Why are you all surrounded here?"

In the past few days, everyone has gotten to know Song Qingyuan a lot and knows that he is an approachable boss.Therefore, he was not afraid when he saw him, and went directly to him, and asked curiously: "Your Highness, can this big thing really squeeze out oil?"

Song Qingyuan nodded and didn't explain much. After saying, "I'll know if we can squeeze out the oil later," he asked the attendants behind him to bring a large pot of soybeans.

Under the watchful eyes of everyone, the pot of soybeans was first crushed into granules on a stone mill, and then put into a steamer and steamed on the fire for half an hour.

After steaming, Song Qingyuan poked it with a wooden pestle to confirm that it was all cooked, then asked someone to wrap it in a cage cloth and press it into a bean cake with a heavy object.

Finally arrived at the step that everyone was most looking forward to.

Two soldiers put the pressed bean cakes into the oil press.As the wedge-shaped wooden blocks were nailed in one by one, soybean oil began to come out of the oil outlet intermittently.

"Look, look, the oil is really squeezed out!" The soldiers exclaimed one after another from the side.

The stakes hanging on the other side also went about their work.He hammered the bean cake again and again, trying to squeeze more oil out of it.

The tub at the oil outlet is quickly filled.

The soldier standing next to Song Qingyuan saw this scene most clearly, and couldn't help but half admired and half puzzled and asked: "Your Highness, how did you come up with such a machine?

This is not his own invention.

This is clearly the result of the wisdom and labor of the working people for thousands of years of continuous improvement and creation.

Song Qingyuan sighed and said with emotion: "It's just the wisdom of the predecessors."

But unfortunately, the Chinese of the soldiers standing next to him is not good, just barely able to communicate with others.Therefore, he directly heard "predecessors" as "immortals".

Hearing this, he murmured in his heart: This Third Highness of Yanyun is really not an ordinary person, even his appearance looks like a banished fairy...

Song Qingyuan didn't know that the people around him had some kind of strange misunderstanding about him.

He got up and walked out of the courtyard gate, and told the people outside the gate: "On the South Street of Wangcheng, there is a young woman who sells straw weaving. You go and find her. If she asks, just say that she bought her that day." A man who weaves straw rabbits seeks her."

The guards took the order to leave, leaving Song Qingyuan staring at the distant snow mountain in a daze.

Ever since meeting that woman that day, Song Qingyuan has been thinking about this matter.

The words explained by the servant that day are still deeply in his mind.These people were not an exception in the royal court, so he wondered if he could find a job for these women and children to make a living.

It just so happens that manpower is also required to cook soybeans now.

Song Qingyuan simply vacated this position and reserved it for those who, like the woman he saw that day, had difficulty making ends meet.

Soon, the woman was led in by the soldiers.

On the way, she knew that the son of that day was actually the rumored Third Prince Yanyun.

Seeing Song Qingyuan, she was about to salute with some trepidation, but she didn't expect that the other party smiled and asked someone to help her up.

"I have a job here, which can ensure that you and your family have enough food and clothing, but it's a bit hard. I don't know if you want it."

The woman raised her head in disbelief and looked at Song Qingyuan.

The spring breeze's tone of the person opposite successfully soothed her uneasiness.

She nodded excitedly, and remembered that women in the Central Plains always called themselves "concubines", so she quickly said: "Concubine is willing! Concubine can suffer all kinds of hardships."

Hearing this, Song Qingyuan asked someone to bring her in and explained to her in detail what she needed to do.

The stove for steaming soybeans is built in the yard. At this time, you can see the steam coming out of the yard continuously.

Song Qingyuan looked at the white steam in front of him, and thought: It's a pity that all the heat is wasted.
