How is the latest progress of a certain research, before the Internet era, is a problem that puzzled many researchers. Especially for those niche topics, apart from the communication between researchers, they can only be solved by searching through newly published journals.

In the 1980s, this problem became more difficult. Because China has been practicing politics in closed doors for more than ten years, apart from Marx's theory, any new discoveries in foreign countries can no longer be solved by rummaging through the journals published in the latest few months. On the other hand, it is also difficult to confirm whether there have been related studies in China before due to the absence of researchers and lack of data.

Therefore, when Yang Rui said that he saw a journal that had a solution to the protruding corners of canned food, Duan Hua believed it.

However, Yang Rui was only a high school student after all, and Duan Hua just straightened up a little, and asked calmly and seriously, "Tell me about the four methods."

Rui's mother and Rui's father also looked at their son curiously.

"The first method is to increase the strength of the can itself. In my impression, it seems that it can be replaced with better tinplate?" Yang Rui said deliberately vaguely.

Duan Hua nodded unsurprisingly: "You can use tinplate for tinplate. You can also use imported tinplate. Japan's modulation system is the best, even better than that of the Americans. However, a small factory like ours has no foreign exchange. .”

Speaking of the last sentence, Duan Hua picked up his wine glass a little self-deprecatingly.

In 1982, the foreign exchange gold was expensive, and the central officials had to plan carefully when traveling, and the county-level organizations would never think of using foreign exchange.

Yang Feng knew a lot, picked up his wine glass, touched him actively, and said, "Isn't your factory exporting white striped meat to Europe? I heard that the sales are pretty good. You must have some foreign exchange reserves."

"The retention is also reserved for the main factory. How can our branch factory get indicators. It is impossible to change to domestic ones. Spending more money is not a skill. Besides, domestic tinplate is also very nervous." Duan Hua said very much. Naturally, the Xibao Meat Joint Factory was established in the early years, and now it has become a series of meat joint factories integrating slaughtering, refrigerated storage and transportation, cooked meat products, etc. The cannery was newly built, and the revenue was good, but it was only a junior.

This kind of struggle for power and profit in the big family of state-owned enterprises is beyond the reach of outsiders.

Yang Rui doesn't think that using better materials can solve the problem. Considering the domestic economic situation, new products are developed at low cost, not to mention the revision of old products.

Like when he was a graduate student, facing corporate customers, Yang Rui smiled slightly,

Said: "Then I will continue to the second point."

"Oh, tell me." Due to Yang Rui's change, Duan Hua also became serious invisibly.

"The second point is the temperature of the soup. If you control the temperature well, you can slowly release the pressure difference. The data should say how many degrees, how is it? I guess some tests are needed." Yang Rui couldn't directly read the value in the data, so he tried his best to narrow down.

However, the applicable temperature is naturally different for different production lines and equipment, which always needs to be adjusted by the factory itself. The significance of the manufacturer's after-sales service and the technical department in the factory also lies in this.

Duan Hua scratched his head: "It's a bit difficult to test which temperature is better. The factory lacks talents. The main factory mainly slaughters and divides, and there are no suitable candidates."

The West Fort Cannery is a new plant of the West Fort Meat Factory, which means that it doesn't have many old people to support it, and college students after the resumption of the college entrance examination can't get it. Duan Hua is already at the highest level.

Therefore, even a simple comparison test that an ordinary graduate student can do in later generations, the West Fort Cannery is like a mouse pulling a turtle, and there is nowhere to start.

Yang Rui shook his head, and said: "The third method is to rely on precooking and canning adjustments to solve the problem of protrusions as much as possible. This should be combined with other methods. The precooking is sufficient, the weight of the canning is reasonable, etc."

"We have done this, but the precooking time and the degree of canning are really difficult to determine." Duan Hua has fully entered the state at this time, and really started to discuss technology.

"The precooking time and the degree of canning can continue to be adjusted, at least within a certain range. It should be connected with the temperature of the soup and do some tests."

"That's right...I'll think about it when I get back."

Yang Rui's parents looked left and right, always feeling that there was something wrong with the scene in front of them.

Yang Rui was quite satisfied, took a bite of the food, and said with a smile: "The fourth method can improve the yield rate the most. Before that, let me ask, is the sterilization pot used in the factory?"

"Yes, type, we also call it a sterilization tank."

"Standing?"

"Yes. The freshly packed cans are put in, sterilized at high temperature, then sprayed with water to cool down, and finally packed and shipped away." The uncle has no intention of taking school exams now, and is completely discussing technology. He was convinced that Yang Rui had really read the relevant papers.

Yang Rui pretended to recall, thought for a while, and said, "Is this type of sterilization tank sprayed with water from bottom to top to cool it?"

"Huh? Yes, yes."

Yang Rui suddenly realized: "That's right, if you want to significantly increase the rate of good products, you have to replace the vertical sterilization tank with a horizontal one."

"why?"

"The book only gives the answer, and it's not very detailed. I thought about it for a while, and you see if it's like this..." Yang Rui put on a studious middle school student and said, "If you spray water from below, the water will be on the bottom. If it accumulates, the bottom cans will cool down first, and the top ones will cool down later, right? Moreover, as more water is stored in the bottom area, the buoyancy will gradually increase, and the top cans may float."

After all, Duan Hua has been working on the spot for many years, and nodded while thinking: "That's right, the lower one cools faster, and the upper one cools slowly. It is true that the cans on the top may float, so that the cans on the top will not be completely submerged. Cooling water will cool down more slowly."

Yang Rui continued to go deeper, and said: "I remember the book said that different temperatures can also cause pressure differences..."

"Um……"

"The pressure difference is the culprit of the horns, so this vertical sterilizer itself will cause the horns, so it should be replaced." Yang Rui pushed forward slowly, confident in his heart.

Vertical sterilizers not only cause protrusions, but are also one of the main causes of protrusions. This is the conclusion drawn by more than ten related papers in later generations.

The canning factory currently only has a yield rate of 75%, which is closely related to this. Only by modifying the way of sterilization and cooling first, and then cooperating with other small means, can it be possible to achieve a high yield rate.

The simple but rigorous reasoning caught Duan Hua, and he thought about it without moving.

Rui's mother doesn't understand technology, seeing him like this, she thought that Yang Rui had said something wrong, and said with a smile: "Brother, don't think so much, eat something first, the food is cold."

Duan Hua lowered his head and said nothing.

The small courtyard fell into an inexplicable silence, only the rustling sound of the pear trees being caressed by the breeze, and there seemed to be a faint fragrance coming from it.

"Snapped."

Duan Hua slapped his thigh with a slap, grinning his teeth in pain, but he stood up with the help of the table and said, "I have to go back, I'll drink here for today."

"Hey, what's the matter?" Yang Rui's parents stood up.

"There is a horizontal sterilizing tank in the third workshop. They can use any of them. I will change it and try it. It's too late. Let's go first." Duan Hua picked up the briefcase and wanted to touch Yang Rui's head , paused for a while, patted it on the shoulder, laughed and said: "Yang Rui has really grown up, he helped me a lot, and I will bring you something good next time."

"Is the expert still invited?"

"Please, please come and do the test." While talking, Duan Hua trotted out of the yard and headed straight for the passenger station.
