It is unknown whether the Ming Dynasty people in Mingzhou will buy many of Liancheng's dried red sweet potatoes that came out in advance. But Wu Nanhai always felt that it was too low-end to make money by selling a relatively basic product like this.
Wu Nanhai said: "Going red is just one direction. It's not deep enough and the added value is too low."
.
Mo Xiaoan said: "The problem is that the people of the Ming Dynasty do not need starch, so who will produce the starch and sell it to them?"
"The people of the Ming Dynasty don't need to fool around, we need it ourselves." Huang Dashan smiled enigmatically, "Not to mention the industrial needs, it can also be used to improve our food. Starch can be used to make many products."
Everyone subconsciously stayed away from this mysterious figure. It seemed that he was covered in horrible microorganisms such as bacteria and viruses. In fact, Huang Dashan's biochemical laboratory is full of various useful strains. In addition to various mushrooms, there are also many fermentation strains in the culture medium.
"There is one thing that can satisfy your craving for export and is also useful for improving everyone's food: MSG." Huang Dashan said, "I have special strains available, and the quality will not be bad."
“Isn’t it necessary to use rice when making MSG?”
"Of course rice can be made, but what actually works is starch. So it's not surprising that anything rich in starch, such as red rice or potatoes, will do." Huang Dashan said, "Cooking wine, vinegar, soy sauce, soy sauce, these condiments are originally We can make everything with rice. The reason why food factories did so little in the past was mainly to save food. Now that sweet potatoes are a large source of cheap starch, we can just expand the scale of production."
Shi Niaoren talked about his plan for Glucose Injection, "Wu Nanhai expressed strong support. He said that he would do as much as he wanted. But Shi Niaoren said that he didn't need too much for the time being. Just a few kilograms would be enough."
.
"It doesn't cost much to make glucose injection."
Glucose injections are useful though. But it's not an urgently needed drug. It doesn’t matter whether you do it or not. Shi Niaoren was eager to do it because he wanted to prove that if the pharmaceutical factory continued to invest such a large amount of money in the price committee, it could not fool people by dispensing oral saline all day long.
"The oral saline and herbal tea you prepared are very good. I will prepare more in the future." Wu Nanhai said, "The weather has been hot recently, so we need it very much."
"Actually, I want to make salt soda," Shi Niaoren said. "Cardaneous drinks quench your thirst. But now we don't have baking soda."
"Soda is good, the new favorite of fashion" Looks like Mo Xiaoan is ready to sell cars to the people of Ming Dynasty
.
Baking soda with soda? "Wu Nanhai posted, "When I was a child, I prepared a bad drink according to the instructions in the book! Very unsuccessful. You'd better spare us. I heard that Ma Dugong designed the soda machine? Carbon dioxide can be dissolved directly into the liquid without baking soda. "
"Yes, it is indeed possible. He is copying the ready-made design in history anyway. But where can we find high-purity carbon dioxide? I heard that there are less than twenty large and small pressure-resistant cylinders in total. Making soda is definitely not an urgent matter. .”
Huang Dashan laughed: "You are really modern enough. You only know about chemical preparation and physical processing. You have forgotten about microorganisms. Where does the champagne gas come from? What about beer? This is not made by adding baking soda or directly adding carbon dioxide. of."
"You mean to make beer. Use sweet potatoes?" Wu Nanhai responded quickly.
Huang Dashan nodded: "Making beer requires malt, and wheat and barley are in short supply now. Otherwise, the bananas of the Special Investigation Team would have been dried up long ago. I have never heard of making beer with red wine." He blinked, "But I can make kvass.”
"Kvass?!" several people shouted together. This thing is rare.
They had all heard about this popular drink in Russia and Eastern Europe. This drink is made by fermenting dry bread. It is similar in color to beer and slightly red in color. It has moderate sweetness and sourness, has a fragrant taste, is rich in gas, and has a very low alcohol content. It is a very popular soft drink among the public.
Traditional kvass requires bread leavening, but Huang Dashan knows that some modern kvass made in factories omit the breading process in order to save costs and manufacturing time, and are directly made from starch-rich raw materials, plus several kinds of kvass. Made of natural or synthetic fragrances. In the past, he had helped a Northeastern boss with the red kvass fermentation process.
Mo Xiaoan said: "Kvass is much more advanced than soda! There are many rich people in Ming Dynasty, so Kvass can focus on the rich female market!"
"I think it's good if we drink from the bow." Wu Nanhai said, "Can it be done?"
"Making red kvass is a new technology developed in the 1970s," Huang Dashan said. "The process is simple. The disadvantage is that it does not have the aroma of bread kvass, and there are no synthetic flavors available here, so we have to add something artificially."
"How to seal kvass? There is no soda bottle capping machine, and there is no tinplate to make bottle caps. It is a carbonated drink."
"How to seal champagne, kvass can also seal it." Huang Dashan said. "The cork is tightened with iron wire on the outside, and sealed with wax. The bottle pressure of champagne is much higher than this. I have never seen a bottle capping machine, and I don't think it is high-tech. You can always make a curtain. Tinplate, As long as we have iron and tin, we can make it.”
"Do you want any equipment?"
"A few large tanks are enough." Huang Dashan was confident. "However, the various culture materials I need must be fully allocated - now the demand for bacterial strains and enzymes is increasing, and there are gaps in equipment and culture media."
Unlike traditional kvass production, Huang Dashan's process is very simple.
First, he peeled the sweet potatoes and ground them into a slurry, then mixed it with a slurry with a moderate moisture content. Then he looked at the thermometer and added a small piece of something like a culture medium.
An hour later, he added another piece of something similar, so that every minute on average he would add something that looked very suspicious. During this period, he continued to direct the fire workers to add and subtract fuel, controlling temperature.
"What is this?" Wu Nanhai couldn't help but ask.
"Several enzymes," Huang Dashan replied, "cell dissolving enzymes, pectin decomposing enzymes, several starch enzymes,"
The enzymes added in sequence decompose all the dextrin in the sweet potato flour slurry into sugar.
Then came the fermentation process. He continued to add suspicious substances, this time it was proteolytic enzymes.
Wu Nanhai watched him going back and forth to inoculate, heat, and add water. He was very happy. He was very suspicious of what he was doing. Huang Dashan didn't seem to be making fermented drinks, but he seemed to be making potions.
Sample.
Finally it is boiled. cool down. After filtering, Huang Yan carefully poured the culture solution from the two culture tubes into the juice extracted from the chestnuts. generous
"This is a culture of S. cerevisiae and Bacillus daieri."
"Yeast is easy to talk about. Isn't there a problem with your Bacillus daisyensis?
Wu Nanhai is deeply worried about things like bacilli.
"It's okay." Huang Dashan didn't explain much. Pay attention to the fire workers to control the temperature, always keep the temperature of the liquid at a certain level, and let it ferment slowly. "After the fermentation is finished, it is filtered and bottled, sterilized by pasteurization, and then left to sit for a few days. When it starts to foam, the kvass is ready."
"Is this good?!" Wu Nanhai felt very confused - it was completely different from what he imagined.
"This is the power of bioengineering." Huang Dashan said proudly. "This is just a trial product. If conditions permit, add some natural essential oils, juice, honey, citric acid, etc. to make the taste better.
"Oak acid is really a good thing. It is needed to make canned food and soda. It would be great if the Ministry of Chemical Industry could produce it." Wu Nanhai wanted to control the fact that rubber acid has a certain effect in water purification, disinfection and sterilization, and it can increase protein in livestock feed. digestibility and improve feed utilization.
As for the food processing plants themselves, this food additive is also in great need. It is used as an acidic flavoring agent in the manufacturing of beverages, sodas, candies, snacks, biscuits, cans, dairy products and other foods. Finally, the coconut oil extraction project that is about to start is in need of controlling that oak acid is also an antioxidant in edible oils.
Huang Dashan disagreed: "What are you doing in the Ministry of Chemical Industry?"
"Isn't citric acid coming from a chemical factory?"
"Citric acid is made by fermentation," Huang Dashan said. "Dried potato powder is fermented to produce acid through deep fermentation. This is a unique technology of our country. I also have this kind of bacteria."
"We also have red ones!" Wu Nanhai said.
"Customize a fermentation tank." Huang Dashan nodded, "I remember that the planning committee did not bring a special fermentation tank. The technology of the fermentation tank is not high. It can be made with carbon steel."
So the production of kvass and MSG was included in the plan. Wu Nanhai and Mo Xiao'an discussed it, went to the sub-large library to search for information, and found several sets of architectural design drawings and equipment drawings of local sweet potato processing enterprises. Send it to the Planning Commission for approval. The approval form came out soon.
Mo Xiaoan went to find Jiang Ye and showed him the equipment requirements and drawings. Jiang Ye took a few glances: Is this simply an all-wood structure? Except for the shaft and grinding knife, which are made of iron, they are all made of wood. Even the transmission rods and gears.
"Where did this come from?"
"The one in the big library is the commune's sweet potato processing factory during the Great Leap Forward," Mo Xiao'an said. "It almost doesn't use steel. It's almost all made of wood. It saves materials and is easy to process."
Jiang Ye shook his head: "This kind of thing, if you say it is good, it will be used urgently. If it doesn't sound good, it will look like it to the leaders." He pointed to the structural drawing of the potato washing machine, "The drum of the all-wood mechanism, the hardwood pole, Mu Zhi Gu... tsk tsk, have the designers considered the strength of the material? It has to be shaken manually, with hundreds of kilograms of sweet potatoes and a full pool of water. Even if you call the governor, you may not be able to shake it." He continued to read. "This set of things will be completely destroyed in a few days. Even if it is made entirely of rosewood, it will be the same."
"Isn't that okay for everyone?"
"It's okay to draw the structure, but the materials need to be changed." Jiang Ye took a pen and scribbled on it, "I have to redesign it."
"It will take a few days to complete." Even though Mo Xiao'an was not from the Agricultural Committee, he knew that the red color could not be kept for a long time.
"At least a week." Jiang Ye studied the drawings for a long time. "Gong Wang gave us a meeting on the standardization of machinery manufacturing, requiring all professional processing equipment to be manufactured in a standardized manner and to unify materials and processes. Complete sets of red processing equipment are certainly no exception. So they have to be redesigned. Materials and performance vary. All aspects must be considered comprehensively, and cannot just be based on saving materials. In addition, you also need a prime mover. Otherwise, the machine cannot be driven. Don’t believe that many of these garish Great Leap Forward brochures are just to fool the leaders.”
"I'll apply for a steam engine, and I'll bring a boiler."
"No need. Just apply for a single-cylinder diesel engine. This equipment can be driven by old horsepower. There is no need to worry about steam engines and boilers now. There is a labor shortage. Zhou Billy and his apprentices are building ships. When are they free to build them? The boiler is still a question mark.”
"Diesel. If not, you need to apply for diesel." Mo Xiaoan hesitated greatly. Diesel is a very valuable thing. If you think about it with your toes, you know that it is impossible to get a diesel quota for the sweet potato processing project.
"Use butterfly gas." Jiang Ye began to promote the latest butterfly gas stove launched by the Works and Energy Commission.
This brand-new gas furnace was opened under the auspices of Wang Luobin. The purpose was naturally to use the large number of single-cylinder diesel engines on hand. In addition, the diesel engine factory project he personally presided over was also entering the project implementation stage.
The technical content of single-cylinder diesel engines is very low, and it is used in supporting workshops of machinery factories. Especially with the completion of the foundry workshop, the apprentices in New Spacetime have become increasingly skilled in skills, and manufacturing single-cylinder diesel engines is no longer a fantasy. Compared with steam engines, single-cylinder diesel engines have great advantages in size and fuel efficiency, but the disadvantages are also obvious: there is no fuel, whether it is diesel or vegetable oil that can be used as a substitute. Crossing groups are in severe shortage.
It is obvious that in the next few years, neither vegetable oil nor diesel will be abundant, so the gas generator, an artifact of the oil shortage era, was thought of.
They will not be short of coal. Even if there are no butterflies, they can still find things like straw, cattle feed, and charcoal. Basically there are no worries, and the gas can be directly used by diesel engines and gasoline engines. Just tweak the motivation a little. This way they brought modern vehicles like agricultural vehicles. After adding a gas generator, it can continue to serve them until the crossing group can produce oil.
The gas generator will affect the power output of the engine. However, at the end of World War II, Germany also installed this device on its half-track armored transport vehicles. It is said that even the Black Panther tank was equipped with a butterfly gas generator on an experimental basis. Come to think of it, The impact on power won't be too far off.
Wang Luobin has designed several different styles of gas generators. One of them is a small one specially designed for vehicles, and the other is a complete set of medium-sized gas generators specially designed for enterprises. It adopts the principle of flat suction. The structure of this type of stove is relatively complex, but it can adapt to low-grade fuels. ! ~!
