What is the latest progress of a certain research, before the Internet age, is a problem that plagues many researchers. Especially those niche topics, in addition to the contacts between researchers, can only be solved by going through the newly published journals.

In the age, this kind of problem has become more difficult. This is because the country has been in isolation for more than ten years and has been practicing politics. Except for Marx’s theory, there is nothing new in foreign countries that can no longer be solved by going through the periodicals published in the last few months. On the other hand, it is difficult to confirm whether there is any related research in China before due to the researcher’s file disconnection and missing data.

Therefore, when Yang Rui said that he saw a journal that had a solution to the problem of canned angles, Duan Hua believed it a little.

However, Yang Rui is only a high school student after all. Duan Hua just stood up slightly, and asked calmly and seriously: “Which four methods are you going to talk about.”

Rui’s mother and Rui’s father also looked at her 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 a better tinplate?” Yang Rui said deliberately, vaguely.

Duan Hua nodded unexpectedly: “You can use tinplate for tinplate. Imported tinplate can also be used. Japan has the best modulation and is even better than Americans. However, a small factory like ours has no foreign exchange. .”

Speaking of the last sentence, Duan Hua held up the wine glass somewhat self-deprecatingly.

The cost of foreign exchange in 1982 had to be calculated carefully for the central officials to travel, and the county-level institutions would never think of using foreign exchange.

Yang Feng knew more, so he picked up the wine glass, and took the initiative to touch him, and said, “Isn’t your factory exporting white strips of meat to Europe? I heard that the sales are pretty good, so I have to keep some foreign exchange.”

“The retention is also reserved for the main factory. How can our branch plant get the indicators. It is not possible to change to a domestic one. It is not a skill to spend more money. Besides, domestic tinplate is also very nervous.” Duan Hua said very much. Naturally, the Xibao Meat Joint Factory was built in the years, and now it is a series of joint meat factories integrating slaughter, refrigerated storage and transportation, and cooked meat products. The cannery was just established, with good revenue, and it was just a junior.

This kind of competition for power in the big family of state-owned enterprises cannot be caught by outsiders.

Yang Rui doesn’t think that using better materials can solve the problem. As far as the domestic economic situation is concerned, 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 and said, “Then I will continue to say the second point.”

“Oh, you said.” Due to Yang Rui’s changes, Duan Hua became serious invisibly.

“The second point is the temperature of the soup. If you control the temperature, you can slowly release the pressure difference. The data should be too much. How about it? It is estimated that some tests will be done.” Yang Rui could not directly read the value in the data, so he tried his best narrow down.

However, different production lines and equipment have different applicable temperatures, and the factory always needs to debug by itself. The significance of the manufacturer’s after-sales service and the in-plant technical department also lies in this.

Duan Hua scratched his head: “It’s a bit difficult to test which temperature is better. There is a lack of talents in the factory. The main factory is mainly for slaughter and segmentation, and there is no suitable candidate.”

Xibao Cannery is a newly built factory of the Xibao Meat Union Factory, which means that it does not have many old people to support the scene. After the college entrance examination is restored, college students will not be able to turn to it. Duan Hua is already at the highest level.

Therefore, even if an ordinary graduate student can do a simple comparison test, the Xibao Cannery is still a mouse pulling a tortoise, and there is nowhere to start.

Yang Rui shook his head and said, “The third method is to rely on pre-cooking and canning adjustment to solve the problem of angle protrusion as much as possible. This should be combined with other methods. Precooking is sufficient, the weight of the can is reasonable, and so on.”

“We have done this, but the pre-cooking time and the degree of canning are really difficult to determine.” Duan Hua is already fully in the state at this time, and really started to explore the technology.

“The pre-cooking time and the degree of canning can continue to be adjusted, at least within a certain range. It should be linked to the temperature of the soup and do some tests.”

“Right…I will think of a solution when I go 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 dish, and smiled: “The fourth method is the best way to improve the yield rate. Before that, let me ask first, is the sterilization pot used in the factory?”

“Yes, type, we also call sterilization tank.”

“Vertical?”

“Yes. Put the freshly packed cans in, sterilize them with high temperature, then spray water to cool them, and finally pack them away.” The uncle has no intention of taking school exams now, and is completely discussing technology. He was already convinced that Yang Rui had really read the relevant papers.

Yang Rui pretended to remember, thought for a while, and said, “Is this type of sterilization tank sprayed with water from the bottom to the top for cooling?”

“Huh? Yes, yes.”

Yang Rui suddenly realized: “That’s right, if you want to significantly improve the yield rate, you have to replace the vertical sterilization tank with a horizontal sterilization tank.”

“why?”

“The answer is only given in the book, and it’s not particularly detailed. I thought about it myself, do you think it’s like this…” Yang Rui put on the look of a studious middle school student and said: “If you spray water from below, the water will accumulate in the lower area. When you get up, the cans below will definitely cool down first, and the cans above will cool down, right? Moreover, if there is more water in the lower area and the buoyancy gradually increases, the cans above may float.”

After all, Duan Hua had been on the scene for many years, and he nodded as he thought about it: “Yes, the lower cooling is fast, and the upper cooling is slow. The cans on the top may indeed float. In this case, the cans on the top are not completely immersed. Cooling water will cool more slowly.”

Yang Rui went deeper and said: “I remember the book said that different temperatures will also cause pressure differences…”

“Ok…”

“The pressure difference is the culprit that caused the horns, so this kind of vertical sterilization tank itself will cause the horns, so it should be replaced.” Yang Rui pushed forward slowly, and was sure of it.

Vertical sterilization tanks not only cause horns, but also one of the main reasons for them. This is the conclusion drawn by more than a dozen related papers in later generations.

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

The simple but rigorous reasoning listened to Duan Hua, and remembered it motionlessly.

Rui’s mother didn’t understand technology. Seeing him like this, she thought Yang Rui had said something wrong, and smiled and said, “Big brother, don’t think about it so much. Let’s eat something first. The dishes are cold.”

Duan Hua lowered his head, UU read www.uukanshu.com without saying a word.

The small courtyard fell into inexplicable silence, only the rustling sound from the breeze stroking the pear trees, vaguely, it seemed that there was still a long, dark fragrance coming.

“Snapped.”

Duan Hua slapped his thigh, grinning in pain, but he stood up on the table and said, “I have to go back. I will drink here today.”

“Hey, what’s the matter?” Yang Rui’s parents both stood up.

“There is a horizontal sterilization tank in the third workshop. They can use any of them. I will try to change it. It’s too late, let’s go first, let’s go first.” Duan Hua picked up the briefcase and wanted to touch Yang Rui’s head. , Paused, patted on the shoulder, haha ​​smiled and said, “Yang Rui has really grown up and helped me a lot. Next time I will bring you good things.”

“Then the expert please?”

“Please, please come and do the test.” Duan Hua said as he ran out of the yard with a trot, and went straight to the direction of the passenger terminal.
