In the future, it must not be bloody, and it is actually not clean now, but the black hand hanging the overlord whip is too dirty, and Jian Chen usually leaves it to Zhao Si and others to do. Pen, fun, pavilion www. biquge。 info

There are two signs hanging in his workshop, and it is clear that in addition to the glass factory, there is also a chemical factory, which is something that cannot be clean. So Chen Jian went for a few days except when he installed those pots and pots before, and now he tries not to go.

The deaths and injuries inside are chronic, and seem much more elegant than direct killing.

The pollution is so severe that all kinds of acidic gases are constantly exposed, and even if you are not blind in three to five years, tears in the wind, sore throat, and cough are inevitable. Moreover, these acid gases can easily corrode teeth, and teeth will be scrapped in a few years, so it is not a good thing that the apatite sulfate fertilizer plant planned by himself is realized between the lips and teeth first.

Leaning on the glazed large clay jar, Chen Jian connected a set of simple small cylinder towers for making sulfuric acid, the output is not high, and he temporarily accumulated experience to prepare for the subsequent large-scale production of sulfuric acid used to absorb acid.

If the glass workshop is considered to be a continuous production, it has gone out of the handicraft industry and has the prototype of a factory; So today's sulfuric acid production is still an authentic handicraft industry.

It cannot be produced continuously, the output is not high, and it is still in a state of initial start.

Sulfuric acid is used as a nitrate absorber in the soil production, and it also plays the role of an absorption device like a drug primer.

The glazed pottery jar can ignore the corrosion of sulfuric acid, and its effect is no less than the lead chamber, and these pottery jars are connected together with pottery pipes, and a lot of porcelain balls are installed inside to expand the contact area.

Sulfur dioxide is produced by sulfur, and saltpeter is used as a provider of nitrogen oxides to oxidize sulfur dioxide to sulfur trioxide, and finally the concentration of sulfuric acid is 50% or 60%, which inevitably contains various impurities and nitrogen oxides, but it does not need to be so pure in terms of current use.

In the theoretically best soil sulfuric acid production process, the role of nitrogen oxides is only to transfer oxygen, transfer its own oxygen to the body of sulfur dioxide, get out of it and react with oxygen and then send oxygen to sulfur dioxide, and so on.

This can be tried in the future, but now we can make do with some sulfuric acid.

This is still eight lifetimes away from industrialization, but the progress of the times cannot be achieved overnight.

Nowadays, if enough money is invested to buy lead, customize larger clay jars, and use glass and caustic soda to make water glass as sealing adhesives, it is completely possible to build a sulfuric acid plant with an annual output of tens or hundreds of tons.

The problem is that Chen Jian has no money now, so he can only follow the normal way to make money in light industry first and then raise chemicals.

Glass can be sold directly for money, but sulfuric acid cannot be sold directly for money, Chen Jian understands that now he is not the chief of the chief, and he can only be based on market demand instead of, and is not qualified to concentrate on big things.

In view of this, in order to quickly realize this set of recommended chemical products and gradually develop them with light nutrients, Chen Jian built a supporting black-hearted workshop after producing primary sulfuric acid.

Most organic acids can hydrolyze animal and plant proteins to produce amino acids, and the conditions are not harsh, and the temperature is about 100 degrees.

The resulting amino acids and inorganic acids are mixed with grass ash and alkali to remove acid; Add brine to make it salty; Caramelized caramel at high temperature for sauce color; Filter out the residue inside, and you can sell it as soy sauce.

The taste is actually about the same, the ingredients are similar, except for some carcinogens that have been eaten for a long time, there are few shortcomings, sometimes the taste is more delicious than normal brewed soy sauce, but sometimes it is also a little smelly, and it can be removed by steaming with wheat bran.

Elegant diners may be able to taste it with one mouthful, but ordinary people should not have this ability, the most important thing is cheap, which is a proper bad currency to drive out good money. 10,000 percent of restaurants and restaurants will use this kind of soy sauce, after all, it is not arsenic, and it is carcinogenic many years later, and no one knows that this thing is carcinogenic now, and it does not affect sales.

Considering that in the process of neutralizing hydrolyzed acid claimed sodium amino acid, it will also react with inorganic acid, and if sulfuric acid is used to claim that miscanthus nitrate will cause diarrhea, Chen Jian had to use concentrated sulfuric acid and table salt to co-heat in the absorption method to prepare hydrochloric acid as an inorganic acid for hydrolysis.

Hydrochloric acid is neutralized with plant ash alkali or caustic soda to generate sodium chloride, and by the way, some toxic carcinogenic dichloropropanol is generated in the hydrolysis process.

In this small workshop, Chen Jian produces two types of soy sauce, and the cost is one-fifth of the cost of the brewed soy sauce sold on the market today.

One is the vegetable protein such as soybean cake and rapeseed ball left over from the oil extraction workshop, which should have been removed before hydrolysis, and the step of removing the oil was omitted after being pressed by the oil extraction workshop.

The second is to use the cheap fish here, minced and used as animal protein, the meat is very low in fat, rich in protein, and has a special umami taste.

Both methods are similar, mixing these ingredients with cheap things like rice bran and wheat bran, adding water, and putting them in special clay jars.

Add an appropriate amount of hydrochloric acid, cover with a lid, leave a small clay tube after sealing, boil it on a fire below, heat it for about four or five hours, and complete the hydrolysis.

Filter out the juice with gauze, then use charcoal to absorb the impurities inside, filter it again, slowly heat it to about fifty or sixty degrees, and add wood ash or caustic soda after reaction with hydrated lime.

Before adding acid, weigh to estimate the acid content, and then use the extract of litmus as a simple acid-base indicator, and add material to neutralize it.

After neutralization, add salt to taste.

There is also a large pot next to it, in which the caramel is boiled, fried until caramel-colored, crushed, and added to the blended soy sauce to make the color.

In another large pot, there is malt fried, wheat can be bought with money, and it is easy to splash water to produce sprouts, and after frying, it is packed in a cloth bag and soaked in soy sauce. One can be colored, and there is also a wheat fragrance; The starch in the second can make the soy sauce thick, which looks different from those sloppy sluts.

After all this, even if the production of the cheapest soy sauce is completed, not counting the five or six days of continuous production of fried malt in the last step, in fact, the cycle of producing a batch of soybean soy sauce or fish soy sauce is only seven or eight hours.

Not to mention that normal breweries need the good craftsmanship of craftsmen and apprentices, even this production cycle is not comparable to those soy sauce factories, and the utilization rate of various raw materials cannot be compared.

It seems that Chen Jian's workshop uses sulfuric acid, which is also considered a cost, but the sodium sulfate produced by sulfuric acid and sodium chloride can be heated with charcoal to produce sodium sulfide. Sodium sulfide reacts with limestone to form sodium carbonate and calcium sulfide.

Calcium sulfide, charcoal powder and the remaining limestone are insoluble in water, and sodium carbonate can be obtained by adding water to dissolve and filter, which is the raw material for making glass.

This is a self-circulating system, hydrochloric acid hydrolysis of soy sauce is a by-product, there is no time to make pyromanganese ore as a filler catalyst, and there is no way to heat hydrogen chloride in a pottery tube to make chlorine, otherwise you can make some bleaching preparations. This can not rob anyone's job, but also collude with those textile workshop owners and preparations in Mincheng.

If the glass workshop is considered technology and capital, this soy sauce workshop is completely a black money to find a way to reduce costs.

These are two models, the former can engage in technology monopoly, or even engage in internal welfare, flickering, mutual benefit and win-win cooperation, and capital-industry cooperation to create a better tomorrow, and it is no problem to make some workers' aristocratic cooperatives; The latter is to find a way to reduce costs, pursue profits, and do not hesitate to hurt nature, which is analogous to the bandages of the wounded in the form of black-hearted cotton.

The consumption of this thing is not large, and if the price is reduced, Chen Jian pondered that those people would definitely not be able to compare with him, and there were no speculators who took the opportunity to hoard this thing.

I think that those normal brewing craftsmen and workshops who have guarded the craftsmanship for generations are afraid that they will be finished.

Either change careers to make vinegar and liquor and sell sauce, or you have to leave the brewing industry completely, high-end consumption can't support so many brewing workshops, and they can't grab the low-end consumer market.

This is the same reason why Chen Jian hesitated to come up with a multi-spindle spinning machine, and now in this place where the natural economy is about to disintegrate and the commodity economy is relatively developed, it is that capital has devoured individual handicrafts, and a large number of people have gone bankrupt and become hired laborers.

But it is only a matter of time, and sooner or later we will have to take such a path, machinery, capital, concentration, crowding, bankruptcy, and reduced to hired hands with nothing but labor......

The difference between late death and early death is that there are fewer people who make soy sauce and no big mess, while there are too many people weaving and spinning, and Chen Jian is not able to clean it up now.

In addition, there is a lack of an external pressure relief valve, and it will not be good for some careerists to use it to forcibly disintegrate the commodity economy and restore the small peasants, so as to start a civil war. At present, the interest groups of maritime merchants, workshops, handicrafts, and coal and iron smelting have not yet occupied a complete advantage, and it is enough to win a civil war, and there is no external colonization to drag the navy into the water, so it is still very fragile on the whole.

Chen Jian suddenly thought of the brewing workshop by the river that he accidentally saw when he first came to this world and went to the dock with Zhang Xuan, the appearance of the workshop owner was completely unrememberable, but those soy sauce jars were still in his mind. This is an irrelevant person, but he will be tricked by fate and swallowed by the times in this era.

In the same way, the times are just as cruel to Jian Chen, he does produce a bunch of things now, and it looks like the prospects are quite good.

But there is also a most thrilling jump from commodities to currency, and if you can't jump out, these commodities and yourself will be crushed. If you can't sell it and turn it over, this workshop will be finished, and the first pot of gold that you have earned in two years is equal to playing in vain.

At this time, he naturally thought of Hu Lin, so he called Zhao Si and asked him to go to the trading company in Mincheng and let Hu Lin come to discuss some important matters.
