After salting out, a metal pipe slowly drops down from the top of the container and extends into a thick layer of sodium fatty acid. Then another Rune square plate is activated, and a pump integrated in the container makes a "buzzing" vibration.

The fatty acid sodium is quickly sucked away by the metal tube, and the fatty acid sodium in the container is reduced at the speed visible to the naked eye.

Seth quickly took the Lord and the consul to another container.

"Lord, madam consul, there are two more processes, namely" steam washing "and" alkali precipitation ". The purpose of these two steps is to further purify the soap based solution and reduce the impurities in it..."

"In previous experiments, we found that boiling the soap based solution with boiling water can make it more uniform, decompose the residual glycerin, pigment and other impurities, and improve the purity of the soap based solution..."

With Seth''s explanation, a large amount of hot water was suddenly ejected from the container, a thermal magic heater under the container was also started, and the soap based solution soon began to boil.

More than ten minutes later, the original slightly yellowish soap based solution has become milky white, and a small amount of condensed sodium fatty acids have also completely dispersed, which makes it look more delicate, and its appearance has greatly improved.

When the pump pumped the solution to the third container, Seth began to talk again.

"This step is alkali precipitation, that is, secondary saponification, because there are still a little oil and impurities in the sodium fatty acid. After adding caustic soda and salt, and waiting for another 20 minutes, the alkali precipitation is completed..."

"After the second saponification, we will see that the solution is divided into two layers, the upper layer is pure saponification, and the lower layer is dark colored waste. These waste materials do not need to be poured out, and can continue to react in the next alkali precipitation..."

"After this step, the purity of sodium fatty acid in soap base solution will exceed 99%..."

In the "alkali precipitation" process, the change in the container is not obvious, the color and viscosity of the soap based solution have almost no change, only a thin layer of yellow liquid appears at the bottom layer, which is not even visible to people with poor eyesight.

When he came to the fourth container, Seth''s face became a little strange and his voice lowered a little.

"Sir, the purpose of this step is to add two resins and water-soluble sodium silicate powder to the soap based solution as As a filler... "

After hearing this, the consul could not help laughing. She knew that the idea must have come from Renault, a very bad guy.

Renault''s calculation is simple: cheating.

No, make money!

After adding fillers, the extremely cheap resin can be sold at the price of soap, and by the way, the content of sodium fatty acid in soap can be reduced.

In other words, the consumption rate of soap will be greatly accelerated, and the tide collar can sell more soap.

With this trick alone, the profit of soap can be increased by at least 20%, so Renault did not hesitate to ask Seth to do his best to find some suitable fillers.

MMP, the way of filling agent, is to learn from the earth people, just look for a few different brands of soap, do you have "rosin" in the ingredients list?

Can rosin be used for decontamination?

Get some wool!

On earth, the price of rosin is 5 or 6 yuan per kilogram. If you buy it in large quantities, the price can be lower.

What about the cost of soap base, that is, fatty acid sodium? Even with the cheapest vegetable oil, the price is more than twice as high as that of rosin. No fool will add it.

In the alien world, all kinds of trees grow as high and fast as eating jinkela, and resin is secreted like no money, which means that the cost of resin is lower.

Renault is very confident about this. Why can''t the unscrupulous businessmen on earth do it well and our master can''t do it?

But Seth''s conscience has not been eaten by the dog as someone did. He is still a little uncomfortable with the practice of "shoddy as good". He only has to do so under the command of the Lord.

"What is the content of fillers?" Renault asked suddenly.

"About 10%, this ratio has little effect on the cleaning effect, but the color of the soap will be a little red, which is the color of red maple resin..." Said Seth.

"Does smell matter?" Renault asked again.

"There is no effect. The aroma of red maple resin is stronger and the smell will be better." Seth shook his head.

"Then increase the proportion of additives to 15%," strong fragrance "is also a good selling point. It doesn''t matter if it turns red, as long as there are no impurities..." Renault laughed with satisfaction.

Big profiteer!

Seth lowered his head and twitched at the corner of his mouth: "I will do as you will."

He gestured to Renault again: "Sir, here is the last process. In this step, we will see the finished soap..."

Seth walked quickly to the last machine and began to explain excitedly.

"This is the" soap forming equipment "we have just developed. It injects the molten soap into the mold, and the cooled soap is the final product...""The first mock exam is 80 chamber design, and 80 soap can be produced at one time."

This machine is no longer a cylindrical container used in the previous processes, but a square silver white equipment. From several Rune square plates on the surface of the equipment, Renault identified that one of them is the rune Group [thermomagic conversion], whose function is obviously to cool the fatty acid sodium.

Seth waved, and a magician immediately stepped forward and started three Rune squares in turn.

The dark blue light covered the rune square board for more than ten seconds, and then gradually faded away. Then the machine suddenly vibrated, and a large metal cover on the top slowly turned over, and a pleasant smell of resin instantly spread.

After the metal cover was completely opened, 8 rows of soap were printed into people''s eyes, each row had 10 pieces of soap, a total of 80 pieces.

Two workers who had been waiting for a long time quickly took down the soap and put it neatly in a wooden box coated with a thick layer of resin.

Renault waved curiously, and a piece of soap flew into his hand.

The soap weighs less than 250 grams and is similar to a cuboid in shape, but its four corners are smooth and the middle is slightly narrowed. This is for easy grasping. There are four simple spray patterns on the upper and lower surfaces of the soap. Under the spray, there is a common line: the flower of the tide.

This is the advantage of extrusion molding. As long as the mold is made, no matter how complex the shape of soap is, it can be easily made.

If we use the hand-made method to carve the spray pattern alone, it will take 5 or 6 minutes. It will take at least 4 hours to make 50 pieces of soap, but it can be done in less than 1 minute by relying on the mold.

Spray patterns and words are the logo of the brand, which naturally comes from Renault''s indoctrination.

even woodlouse does not understand industrialization. There is no idea about the benefits of building brands, but in the future, they will realize the huge benefits of branding sooner or later.

Once the word "Haichao" is engraved into the minds of the people of other worlds, the price of any commodity can rise by a fraction out of thin air as long as it is engraved with these two words.

As for piracy, there is no need to worry about it.

How can handmade products be compared with machine-made products? They will only steal and lose, and fools will pirate.

Seth''s commentary continued as Renault focused on the soap.

"Lord, madam consul, there are only seven employees in this soap line, five of them are responsible for operating the machine, and the other two are responsible for picking up products..."

"We have calculated that if the production mode of three shifts is implemented, the maximum output can exceed 100000 yuan per day, and the annual output can reach as high as 30 million yuan..."

Hearing this terrible number, all the onlookers gasped and looked at the machines with unbelievable eyes.

What is the concept of 30 million yuan?

According to the most rough statistics, the population of the whole human world is only over 20 million. In terms of families, there are about 4 million families, of which only 1 million can afford soap.

If every family consumes an average bar of soap in half a month, the total demand is only 24 million.

This also means that this factory with an area of no more than 1000 square meters and these five machines can meet the needs of the whole human world.

Even if in the future, with the development of economy, the purchasing power of civilians will increase and the demand for soap will double, it will only be a matter of adding one production line.

Renault can be proud to declare: the soap of all mankind is contracted by labor and capital alone!

This is the real industrialization.

also has soap. What is the productivity of woodlouse''s soap workshop?

Craftsmen can only produce one cylinder of soap, and after one cylinder is made, the next one will begin.

After the oil and caustic soda are put into the pottery jar, they can only be stirred manually. This method is not only laborious, but also inefficient in saponification reaction. It takes at least three hours.

With the subsequent cooking, cleaning, salting out and purification, another three hours have passed.

Finally, cool the soap base and cut it into pieces. It takes about 2 hours.

That is to say, it takes eight hours to produce one cylinder of soap, and only two cylinders of soap can be produced in a day.

In addition, manual production can''t produce 1 ton per can. Craftsmen can''t bear the labor intensity. They can produce 100 kg at a time, which is equivalent to 400 pieces of soap.

However, one advantage of handcraft is that it requires a small number of people, and four craftsmen can start the work.

Based on this calculation, the annual output of a small workshop with four people is 300000 pieces at most, and the per capita output is less than 80000 pieces.

But it''s just an ideal state. It''s impossible in reality.

Because in this era of extremely low productivity, they simply can''t get enough animal fat. Their annual output has to be 20% off, that is, 80000 yuan, and the per capita output instantly becomes 20000 yuan.

What about the tide collar?

Even if the production line reaches full capacity, it will not need more than 25 workers, and the average person will produce 1.2 million pieces of soap every year.It''s 60 times more than manual production!

Not only the production efficiency is more than ten blocks away from manual production, but also the labor intensity is greatly reduced by relying on machines.

So, can tide collar solve the problem of grease?

Of course!
