It is unknown whether the people of Ming Dynasty in Guangzhou would buy Liancheng Dried Sweet Potatoes, which was released in advance, but Wu Nanhai always felt that it was too low-end to make money from such a relatively elementary product as dried sweet potatoes.
Wu Nanhai said: "Dried sweet potatoes are considered one direction, but the development depth is not 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 it, we ourselves need it." Huang Dashan smiled enigmatically, "Not to mention 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 exuding terrible microorganisms such as bacilli and viruses. In fact, 99% of Huang Dashan's biochemical laboratory is filled with various useful bacteria. In addition to various
In addition to various mushrooms, there are many fermentation strains in the culture medium.
"There is one thing that not only satisfies your export habit, but 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 sweet potatoes, potatoes and other starch-rich foods will do." Huang Dashan said, "Cooking wine, vinegar, soy sauce, and soy sauce, these condiments were originally used by us.
It can be made 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 glucose injection plan, and Wu Nanhai expressed strong support. He said that he would do as much as he wanted. However, Shi Niaoren said that he didn't need too much for the time being, just a few kilograms.
"It doesn't cost much to make glucose injection."
Although glucose injection is very useful, it is not an urgently needed drug. It does not matter whether it is done or not. Shi Niaoren is eager to develop it because he wants to prove the value of the existence of the pharmaceutical factory - the executive committee cannot make such a large investment in one day.
Taking oral saline at night can fool people.
"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 I need them especially."
"Actually, I want to make salt soda." Shi Niaoren said, "Carbonated drinks can quench your thirst. But now we don't have baking soda."
"Soda is good, the new favorite of fashion -" It seems that Mo Xiao'an is ready to sell soda to the people of Ming Dynasty.
"Baking soda with soda?" Wu Nanhai asked, "I did it according to the book when I was a child - it tastes bad! It was very unsuccessful. You should spare us. I heard that Ma Dugong designed a soda machine? No need.
Baking soda can directly dissolve carbon dioxide into liquid."
"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, so it is definitely not urgently needed to make soda.
thing."
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 air of champagne come from? What about beer? This is not adding baking soda or directly adding carbon dioxide.
Made it."
"You mean to make beer with 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 a long time ago. I have never heard of sweet potatoes making beer." He blinked, "But I
Can make kvass.”
"Kvass?!" Several people shouted together. This thing is rare.
They have all heard of the name of this drink, which is very popular in Russia and Eastern Europe. This drink is brewed by fermenting rusk. It is similar in color to beer and slightly red, has moderate sweetness and sourness, has a fragrant taste, and is rich in gas.
It has a very low alcohol content and is a very popular soft drink.
Traditional kvass is fermented with bread, but Huang Dashan knows that some modern kvass made in factories omit the bread 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 aromatics. In the past, he helped a Northeastern boss with the fermentation process of sweet potato kvass.
Mo Xiaoan said: "Kvass is much more advanced than soda! There are many rich people in Ming Dynasty, so Kvass can focus on the female market of rich people!"
"I think it's good if we can drink it ourselves." Wu Nanhai said, "Is that okay?"
"Making kvass from sweet potatoes is a new technology developed in the 1990s." Huang Dashan said, "The process is simple, but 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 wire on the outside and sealed with wax. The bottle pressure of champagne is much greater than this. I have never seen a bottle cap machine.
, I guess it’s not a high technology, it can always be made in the future. Tinplate can be made as long as there is iron and tin.”
"Do you need any equipment?"
"A few large tanks are enough." Huang Dashan was confident, "But the various culture materials I need must be fully allocated - now the demand for strains and enzymes is increasing, and the equipment and culture media are all available
gap."
Different from the traditional kvass production, Huang Dashan's process is very simple. First, peel the sweet potatoes and grind them into a powder slurry, then add a slurry with a moisture content of 75%. Then he looks at the thermometer and adds a small piece of culture medium.
Something similar.
An hour later, he added another similar item. In this way, on average every 30 to 60 minutes, he would add something that looked very suspicious. During this period, he continued to direct the fire workers to add or subtract fuel, controlling
temperature.
"What is this?" Wu Nanhai couldn't help but ask.
"Several kinds of enzymes." Huang Dashan replied, "Cell-lysing enzymes, pectin-decomposing enzymes, several amylase..."
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 amused. He was very suspicious of what he was doing - Huang Dashan didn't seem to be making fermented drinks, but rather like preparing potions.
After boiling, cooling, and filtering, Huang Dashan carefully poured the culture solution from the two culture tubes into the filtered juice.
"This is a culture medium of S. cerevisiae and Bacillus daikonii."
"It's easy to talk about yeast. Your Bacillus daisii won't be a problem, right?" Wu Nanhai was deeply worried about things like Bacillus.
"It's okay." Huang Dashan didn't explain much. He asked the fire workers to control the temperature and keep the temperature of the liquid at 26 degrees Celsius to let it ferment slowly. "After 16 hours, the fermentation is completed and then filtered and bottled, and pasteurized.
Disinfect it, then let it sit for a few days, and when it starts to foam, the kvass will be ready.”
"Is this good?!" Wu Nanhai felt 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."
"Citric acid is really a good thing. It is needed for canning and soda. It would be great if the Ministry of Chemical Industry could produce it." Wu Nanhai thought that citric acid has a certain effect in water purification and disinfection, and it can improve protein digestibility when added to livestock feed.
, improve feed utilization.
As for food processing plants themselves, this kind of food additive is also in great demand - it is used as an acidic flavoring agent in the manufacture of beverages, sodas, candies, snacks, biscuits, cans, dairy products and other foods. Finally, citric acid is also an antioxidant in edible oils.
Oxidizing agent - needed for the coconut oil extraction project that is about to start.
Huang Dashan disagreed: "What are you doing with 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 submerged in citric acid - this is a unique technology of our country. I also have this kind of bacteria."
"We also have sweet potatoes!" Wu Nanhai said.
"Customize a fermentation tank." Huang Dashan nodded, "I remember that the Planning Commission did not bring a special fermentation tank. The technical content of the fermentation tank is not high, and it can be made with carbon steel."
So the production of kvass and monosodium glutamate was included in the plan. Wu Nanhai and Mo Xiaoan 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 slip will come out soon.
Mo Xiaoan went to Jiang Ye and showed him the equipment requirements and drawings. Jiang Ye took a few glances and asked: Is this an all-wood structure? Except for the shaft and the grinding knife, which are made of iron, they are all made of wood.
.even the transmission rods and gears.
"Where did this come from?"
"In the big library, there are drawings of the commune's sweet potato processing plant during the Great Leap Forward." Mo Xiao'an said, "Almost no steel is used, almost all are made of wood, which saves materials and is easy to process."
Jiang Ye shook his head: "This kind of thing, if it sounds good, is for emergency use. If it sounds bad, it just looks like it is for the leaders to see." He pointed to the structural drawing of the potato washing machine, "The rollers of the all-wood mechanism, the hardwood levers, and the wooden gears
...Tsk tsk, have the designers considered the strength of the materials? 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 this set of things." He continued to look at it, "This set of things
Once it is made, it will be completely destroyed within a few days. Even if it is made entirely of rosewood, it will be the same."
"Isn't that right?"
"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." Although Mo Xiao'an is not a member of the Agriculture Committee, he also knows that sweet potatoes cannot be stored for a long time.
"At least a week." Jiang Ye studied the drawings for half a day. "Gong Wang gave us a meeting on mechanical manufacturing standardization, requiring all kinds of professional processing equipment to be manufactured in a standardized manner and to unify materials and processes. The complete set of sweet potato processing equipment is certainly no exception.
.So we have to redesign it. All aspects of materials and performance must be considered comprehensively, and we cannot just start from saving materials. In addition, you also need a prime mover. Otherwise, the machine cannot be driven. Don't believe this garish Great Leap Forward brochure -
―Many of them are trying to fool the leaders.”
"I'll apply for a steam engine, and I'll bring a boiler."
"No, just apply for a single-cylinder diesel engine. This equipment can be driven with 10 horsepower. There is no need to think about steam engines and boilers now - there is a shortage of riveters, and Zhou Billy and his apprentices are building ships. When will they be available?
Building boilers in vain is still a question mark."
"Diesel, you don't have to apply for diesel -" Mo Xiao'an 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.
"It's better to use gas." Jiang Ye began to promote the gas generator newly developed by the Works and Energy Commission.
This brand-new gas generator was developed under the leadership 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 directed was also entering the project implementation stage.
The technical content of a single-cylinder diesel engine is very low. With the completion of the supporting workshops of the machinery factory, especially the casting workshop, the apprentices in the new space are becoming increasingly skilled in skills. Manufacturing a single-cylinder diesel engine is no longer a fantasy. Compared with steam engines, single-cylinder diesel engines
The advantages in terms of volume and fuel efficiency are huge, but the disadvantages are also obvious - without fuel, whether it is diesel or vegetable oil that can be used as a substitute, the Crossing Group is in serious shortage.
It is obvious that in the next few years, neither vegetable oil nor diesel will be abundant, so the gas generator, an artifact in the era of oil shortage, was thought of.
They will never be short of coal. Even if they don't have coal, straw, wood, charcoal and the like, they can still find it. Basically, there is no need to worry about anything, and coal gas can be directly used by diesel and gasoline engines, as long as the engine is slightly adjusted.
That's it. In this way, the modern vehicles they bring, such as agricultural vehicles, can continue to serve them after being equipped with a gas generator until the Crossing Group can develop oil.
The gas generator will affect the engine power output. 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 nearly 50-ton Panther tank had a gas generator installed on an experimental basis. I think you are right.
The impact of power won't be too far off.
Wang Luobin has designed several different styles of gas generators. One of the small ones is specially formulated for vehicles, and the other is a complete set of medium-sized gas generators specially designed for enterprises. It uses the flat suction principle. This kind of stove
The structure is relatively complex, but it can adapt to low-grade fuel.
