In the past two days, the rapeseed oil has been prepared, and in his free time, Liu Yuanshan began to organize people to produce another thing, that is, caustic soda water, the principle of this thing is difficult to understand, but in fact it is very simple to make. Pen "Fun" Pavilion www.biquge.info

He didn't want too many people to know the secret of osmanthus soap manufacturing, so the whole process was divided into three stages.

Some people make plant ash to precipitate liquid, some people extract caustic soda solution from lime water, and the last part is the mixing of the two solutions.

Stirring is a secret among secrets, and the people used are naturally their own family, in addition to the old sister, there are also Xiaoyu and Xiaoqing.

After the caustic soda solution in Qianning Temple was made, he ordered someone to send it to the front yard of his house, and asked Han Laotie to take Shengsheng and Hong Zongwei to install the steam engine, stirrer and boiler in a certain room, and the production equipment was complete.

The first large-scale stirring Liu Yuanshan personally operated.

The stirring container was a large rough vat, and half a vat of 200 catties of solution was poured into it, and then the steam engine started, and the mixer trembled with the rotation, and a vat of solution was stirred up rapidly.

Under normal circumstances, manual stirring, even if it is dozens of catties of solution, it takes two or three hours to stir the grease and caustic soda water evenly, now stirring with a steam engine, a cylinder of solution has 200 catties, but the time required is greatly reduced, only half an hour of time, can be stirred evenly.

The reason why Liu Yuanshan increased the production of osmanthus soap, in addition to wanting to promote and obtain greater benefits, another more important reason is that after a winter of sales, the market of the entire Xiangyang Mansion has become nearly saturated.

Before the end of last year, almost five or six hundred pieces of soap were sold, but after the beginning of spring this year, few people came to buy it again, not because these people no longer use it, but because they bought enough for the year in advance, and the market is saturated, so they can't sell it.

After all, such a valuable thing is mostly used to clean official uniforms, and how to get the clothes of people and ordinary civilians in ordinary times.

If you want to reap the benefits, you need to redefine your target group!

Liu Yuanshan set his sights on the civilian class, so he could only expand the scale and reduce the cost and sell it at a low price, and open the market of the entire Ming Empire with sales, and then he would naturally have a lot of money.

The "clanging" sound of the steam engine when it was running and the "humming" sound of the stirrer when it was turning converged, and the noise in the entire room almost made Liu Yuanshan collapse. After persevering for half an hour, a jar of solution was finally stirred evenly, and the soap was ready to enter the mold.

"I'm tired!" Liu Yuanshan jumped down from the high platform, looked at Xiaoyu, Xiaoqing and his sister Liu Yanran, and said breathlessly: "Did you see what I did?" ”

"See!" Liu Yanran nodded and said.

Stirring is just a mechanical job, it is not difficult to operate, anyway, the steam engine is running all the time and there is no waste of materials, but the belt is always heating is a big problem.

"Every once in a while, water is poured on the belt to cool down, you know?" Liu Yuanshan personally scooped a scoop of water and slowly poured it on the running conveyor belt, demonstrating to the three of them.

"Yes, we all know, you've said it a few times." Liu Yanran looked at the half jar of soap, and her eyes showed excitement.

Liu Yuanshan stopped the steam engine, and the next time was to enter the mold.

Liu Yanran moved all the five or six hundred molds made by Song Qiu some time ago into the soap production workshop, and the three of them scooped out the soap liquid with a pottery scoop and poured it into the mold, filled it and flattened it, and then put it on a designated platform.

The soap liquid saponification reaction is very fast, and it can be demolded in two hours, so that the mold can also be used repeatedly.

The soap that has just come out of the mold is still very soft, and when it has a little strength, a special person will take the molded soap into another room full of wooden shelves, place it layer by layer, and wait for it to dry and mature slowly.

In general, cold soaps mature for more than a month.

Liu Yuanshan watched the three of them complete all the processes meticulously, and then left with peace of mind.

In this way, the soap was produced piece by piece, transported out to dry and mature, and the people of the Liu family were also busy all day long.

At night, the mountain breeze is quite cold!

The people of the Liu family were so tired that they couldn't straighten their waists after a busy day, and many people fell asleep deeply.

There were two thin figures in the courtyard who were still busy, covered by the dim yellow light of the lantern at the corner of the gatehouse, their figures were pulled on the ground, one long and one short.

Although they were tired for a day, Xiaoyu and Xiaoqing did not rest, because the conveyor belt of the steam engine was overheated and burned out and could not be used, the two of them were ready to use the most primitive manpower stirring method to finish the last bit of osmanthus soap.

"Sister, there is one last bucket of rapeseed oil!" Xiaoyu said, pointing to a wooden barrel of oil in a corner. The oil drum was two feet high, and there was a big word "oil" on its belly!

"Let's go, let's carry it over and pour it into the mixing bucket!"

Two emaciated figures walked over to the barrel, rolled the oil drum to the mixing barrel, and poured it into it with great difficulty.

"And greywater!" Xiaoyu pointed to a clay pot with the word "urine" written on it next to him and said to Xiaoqing, "Let's go and carry it over too." ”

It turned out that there was a temporary lack of containers at home, and when making caustic soda water, I used urine jars that I bought last time but didn't use them, and many of them still had signs written on them that they had not been removed.

"Good!" Xiaoqing nodded.

"Sister, what do you pronounce this word?" Xiaoyu asked, pointing to the words on the clay pot. She didn't know how to read, but she was curious.

"Ah, it's urine!" Xiaoqing smiled and pointed to the words, and said a word to Xiaoyu, but did not explain too much.

The two lifted the clay pot full of "urine" and slowly poured it into the mixing bucket.

What they didn't know was that at this moment, there were two pairs of eyes hidden behind the courtyard wall, watching their every move.

At night, the top of the mountain is silent, and there is no one to visit! A very light word can sometimes go far and wide.

When Zhao Yuan, who was outside the wall, heard Xiaoqing's words, the sleepiness and tiredness that had been in his body disappeared in an instant, his eyes were full of incredible excitement, and his body shook involuntarily.

I see!

It's really hard to find a place to break through the iron shoes, and it takes no effort to get it.

Liu Yuanshan, Liu Yuanshan, I said how did you collect feces and urine some time ago, no wonder you have to buy so much rapeseed oil, it turns out that these two things are the raw materials of osmanthus soap.

It's been sent.,It's really going to be sent now.。

Hehe, I'm going to be the number one hero of the Zhao family soon! (To be continued.) )
