It is unknown whether the people of Daming in the state will buy the Liancheng dried sweet potatoes that came out in advance. But Wu Nanhai always felt that it was too low-grade to make money by selling such a fairly rudimentary product.

Wu Nanhai said: "Red work can be regarded as a direction, the depth of development is not enough, and the added value is too low.

Mo Xiaoan said: "The problem is that the people of Daming don't need starch, who do they produce starch to sell to?" ”

"The people of the Ming Dynasty don't need to play, we need it ourselves." Huang Dashan smiled incomprehensibly, "Not to mention the needs of industry, it is also good to use it to improve our food." Starch can be used to make many products. ”

Everyone subconsciously stayed away from this mysterious figure. It seems that he is full of terrifying microorganisms such as bacteria and viruses. In fact, the names of the feathers in the biochemical shiyan room of Huangdashan are all kinds of useful mushrooms, and in addition to various mushrooms, there are also many fermentation strains in the culture medium.

"There is one thing, that is, to satisfy your export habits, it is also useful to improve everyone's food." Huang Dashan said, "I have special strains available, and the quality will not be bad." ”

"Doesn't making MSG say that you need to use rice?"

"Of course, rice can also be made, but in fact, it is starch that works. Therefore, it is not surprising that red and potatoes are rich in starch. Huang Dashan said, "Cooking wine, vinegar, soy sauce, sauce, these condiments were originally made with rice, and the reason why the food factory did little before was mainly to save food." Now that sweet potatoes are a source of cheap starch, it is possible to directly expand the scale of production. ”

Shi Yuanren talked about his glucose injection jihua, "Wu Nanhai expressed strong support. Say how much you want to do. However, Shi Yuanren said that it is not necessary to have too much for the time being. A few kilograms are fine.

"To do glucose injection, it doesn't cost much."

Glucose injections are useful though. But it's not a much-needed drug. It doesn't matter if you do it or not. Shi Yuanren was anxious to come up with it in order to prove that the price committee of the pharmaceutical factory had made such a big investment, and it could not be fooled by oral saline all day long.

"The oral saline and herbal tea you have are very good, and you will have more in the future." Wu Nanhai said, "The weather has been hot recently, and it is especially needed. ”

"Actually, I want to make salt soda." Shi Yuanren said, "Carbonated drinks quench your thirst. But now there is no baking soda. ”

"Soda is good, the new favorite of fashion" It seems that Mo Xiaoan is ready to sell steam to the people of Daming.

Baking soda with soda? Wu Nanhai took a look, "When I was a child, I was deserved with a bad drink according to what was written in the book!" Very unsuccessful. You'd better spare us. I heard that Ma Dugong designed a soda machine? Without baking soda, you can dissolve carbon dioxide directly into the liquid. ”

"Yes, yes, he copied the ready-made designs from history anyway. But where do we find high-purity carbon dioxide? I heard that there are less than 20 large and small pressure-resistant cylinders in total, and making soda is certainly not an urgent thing. ”

Huang Dashan laughed: "You are really modern enough, you know chemical preparation and physical processing. Forget all the microbes where the champagne gas comes from? What about beer? This is not made by adding baking soda or directly hitting carbon dioxide. ”

"You mean make beer. With sweet potatoes? Wu Nanhai reacted quickly.

Huang Dashan nodded: "Malt is needed to make beer, and now wheat and barley are in short supply." Otherwise, the bananas of the special investigation team would have wanted to dry up a long time ago. I haven't heard of making beer in red. He blinked, "But I can do kvass." ”

"Kvass?!" Several people shouted out together. It's a rarity.

They have all heard of the daimyo of this drink, which is popular in both Russia and Eastern Europe. This drink is made by fermenting rusks, the color is similar to beer but slightly red, the sweet and sour taste is moderate, the taste is fragrant, the gas content is rich, and the alcohol content is very low, it is a very popular soft drink.

Traditional kvass is to ferment bread, but Huang Dashan knows that in order to save costs and manufacturing time, some modern kvass factories save the process of bread, and are directly made of starch-rich raw materials, plus several kinds of natural or synthetic aromatics. In the past, he helped a Northeast boss with the fermentation process of red kvass.

Mo Xiao'an said: "Kvass is much more advanced than soda!" There are many rich people in the Ming Dynasty, and kvass can focus on the rich women's market! ”

"I think it's good that we've got enough of it." Wu Nanhai said, "Can it work? ”

"The red book does kvass is a new ジシュ that developed in the era." Huang Dashan said, "The process is simple. The disadvantage is that there is no aroma of bread kvass, and there are no synthetic flavors available here, so I have to add something manually. ”

"How to solve the sealing of 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. "Cork, tightened with wire on the outside and sealed with wax. Champagne is much more pressurized than that. I haven't seen a bottle cap machine, and I don't think it's high-tech. The curtain can always be built. Tinplate, as long as you have iron and tin, you can make it. ”

"Do you want any equipment?"

"A few vats are enough." Huang Dashan is confident. "However, the various culture materials I need must be fully allocated, and now the demand for strains and enzymes is increasing, and there is a shortage of equipment and culture media."

Unlike traditional kvass making, the process is very simple.

The sweet potatoes were peeled and ground into a slurry with a moisture content, and then he looked at the thermometer and added a small piece of medium.

After an hour, he added another piece of something similar, and in this way he added something that looked very suspicious every minute per blade minute, and during this time, he constantly instructed the burners to add or subtract fuel, and control the temperature.

"What is this?" Wu Nanhai couldn't help but ask.

"Several enzymes." Huang Dashan replied, "Cells are lysed and awakened, pectin decomposition is cool, and several starches are cool,"

Enzymes are added sequentially to decompose all the dextrin in the sweet potato batter into sugar.

Then came the fermentation process, and he continued to add suspicious substances, this time proteolytic enzymes.

Wu Nanhai watched him inoculating, heating, and adding water back and forth, and was very happy, and he was very suspicious of what he was doing, and Huang Dashan didn't seem to be engaged in fermented drinks, as if he was dispensing potions

Shape.

zuihou is boiled. Cooling. After filtering, in the juice of the chestnut, the yellow flail was poured into the culture liquid in the two culture tubes. generous

"This is brewer's yeast and Bacillus deutschi culture."

"Yeast is good to say. You won't have a problem with Bacillus delloni.

Wu Nanhai was deeply worried about things like bacilli.

"It's fine." Huang Dashan didn't explain much. Take care of the burner to control the temperature, always keep the temperature of the liquid at the fork, and let it ferment slowly. "After the old hours, the fermentation is finished, then it is filtered and bottled, pasteurized, and then left for a few days, and when it comes out of foam, the kvass is ready."

"That's it?!" Wu Nanhai was very confused, and it was completely different from what he imagined.

"That's the power of bioengineering." Huang Dashan said proudly. "This is just a trial product, if conditions permit, add some natural essential oils, juices, honey, citric acid or something, the taste is better

"It's a good thing to make oak acid, you need to make cans and soda. It would be nice if the Ministry of Chemical Industry could produce it. "Wu Nanhai wants to control rubber acid, which has a certain water purification and disinfection and sterilization effect, which can improve the protein digestibility and feed utilization rate in livestock feed.

As for the food processing plant itself, it is also in need of this food additive, and it will be used as an acidic flavoring agent in the manufacture of beverages, soft drinks, candies, snacks, biscuits, canned food, dairy products and other foods. ズイユウ rubber control is still an antioxidant of the edible oil, and the coconut oil extraction project which I prepare for the start of work is needed.

Huang Dashan disagreed: "What is the matter with the Ministry of Chemical Industry." ”

"Isn't citric acid from a chemical plant?"

"Citric acid is made by fermentation," Huang Dashan said, "Dried potato powder is deeply fermented, twisted and sour, which is unique to my country." I also have this strain. ”

"We've got it too!" Wu Nanhai said.

"Custom-made fermenters." Huang Dashan nodded, "The Planning Commission I remember didn't bring a special fermentation tank. The fermentation tank jishu content is not high. You can make it with carbon steel. ”

So the production of kvass and monosodium glutamate was included in jihua. Wu Nanhai and Mo Xiao'an discussed, went to the library of the second university to check the information, and found several sets of architectural design drawings and equipment drawings of the local sweet potato processing enterprise. Send it to the Planning Commission for approval. Soon the approval form came down.

Mo Xiaoan went to Jiang Ye to show him the equipment requirements and drawings. Jiang Ye glanced at it a few times: Is this simply an all-wood structure? Except for the shafts and knives, which are made of iron, they are all made of wood. Even the drive rod and gears.

"Where did this come from?"

"In the big library, the commune's sweet potato processing factory during the Great Leap Forward," Mo Xiao'an said, "almost no steel is used, almost all of it is wood, which is material-saving and easy to process." ”

Jiang Ye shook his head: "This kind of thing, if it is said to be different, it will be replaced urgently, and if it is not good, it will be shown to the leader." He pointed to the structural drawings of the potato washer, "The drum of the all-wood mechanism, the hardwood carrying rod, the wooden tooth... Tsk, did the designer consider the strength of the material? It is also shaken by manpower, hundreds of catties of sweet potatoes, plus a pool full of water, and it may not be able to shake it when the governor comes. He continued to watch. This set of things will be finished in a few days. Even if it is made entirely of rosewood, it is the same. ”

"Can't you say that?"

"It's okay to draw the structure, but you have to change the material." Jiang Ye took the pen and scribbled on it, "I have to redesign." ”

"It's going to take a few days to finish." Although Mo Xiaoan is not a member of the Committee of Agriculture, he also knows that he will not be able to let go of his popularity for a long time.

"At least a week." Jiang Ye studied the drawings for a long time. "Wang Gong gave us a conference on the standardization of machinery manufacturing, requiring all kinds of professional processing equipment to be standardized and unified materials and technological processes. The red processing equipment is certainly no exception. So it had to be redesigned. All aspects of materials and properties should be considered comprehensively, and we should not just start from saving materials. Plus, you'll need a prime mover. Otherwise, you can't bring the machine. Don't believe that many of the pamphlets of the Great Leap Forward are fooling the leaders. ”

"I'll apply for a steam engine, just bring a boiler."

"No, you don't. Just apply for a single-cylinder diesel engine. This set of equipment can be driven with old horsepower. Steam engines and boilers don't have to worry about labor shortages now, and Billy and his apprentices are building ships. When there will be time to build a boiler is still a question mark. ”

"Diesel. No, you have to apply for diesel" Mo Xiaoan hesitated, diesel is a very expensive thing, and you know that it is impossible to get diesel quotas for the sweet potato processing project by thinking about it with your toes.

"It's good to use butterfly gas." Jiang Ye began to sell the butterfly gas generator newly developed by the Labor and Energy Commission.

This new gas generator was developed under the auspices of Wang Luobin, and the purpose was naturally to use a large number of single-cylinder diesel engines at hand, and the diesel engine factory project he personally presided over was also entering the project implementation stage.

The jishu content of the single-cylinder diesel engine is very low, along with the supporting workshop of the machinery factory. Especially with the completion of the foundry workshop, the apprentices of the new time and space are becoming more and more skilled, and the manufacture of single-cylinder diesel engines is no longer a fantasy. Compared with the steam engine, the single-cylinder diesel engine has great advantages in terms of volume and fuel efficiency, but the disadvantage is also obvious that there is no fuel, whether it is diesel or vegetable oil that can be used as a substitute. Cross groups are in severe shortage.

It was obvious that neither vegetable oil nor diesel would be abundant in the next few years, so the gas generator, an artifact in the era of oil shortages, came to mind.

They don't lack coal, and even if there are no butterflies, straw, cow feed, charcoal, and the like can still be found. There are basically no worries, and the gas can be used directly by diesel and gasoline engines. Just a little tweaking of the engine is all it takes. So they bring modern vehicles like farm vehicles. With the addition of a gas generator, they will be able to continue to serve them until the Crossing Group is able to develop oil.

The gas generator will affect the power output of the engine, but at the end of World War II, Germany also installed this thing in its own half-track armored transport vehicles, and it is said that even the Panther tank, which is about to stew heavy, has been installed with a butterfly gas generator, and the impact on power will not be too far.

Wang Luobin has designed several different styles of gas generators, one of which is a small one specially prepared for vehicles, and the other is a complete set of medium-sized gas generator for enterprises, which adopts the principle of flat suction. The structure of this furnace is more complex, but it can be adapted to low-grade fuels.
