Li Zhongxin returned home from Paris this time, his father nagged again, his mother nagged again, only his grandmother and grandfather did not say anything about him, just a meal at the Zhongxin Fish House in the evening, and Li Zhongxin's house returned to its previous tranquility.

Two days after reuniting with his family, Li Zhongxin got up early in the morning and came to the headquarters of Zhongxin Company very early, and officially began to work on the design of the extraction grape seed oil machine with the scientific researchers and many experts in cartography who had arrived in Jiangcheng one after another.

When Li Zhongxin went to the provincial capital this time, after talking to Chen Xingran about the automobile production base, he directly called Gamino and told Gamino that everything was negotiated according to the established plan.

As for the extra small conditions, they are nothing, when they were negotiating in Paris, Li Zhongxin had said these plans, and Gemino's side had already agreed to what Li Zhongxin said.

Germino told Li Zhongxin that he would start looking for technicians from France to China as soon as possible to start the official launch of the automobile production base plan of Beverly Cars.

When he went to Japan to complete the formalities with Kujing, he would personally supervise this matter, and he promised Li Zhongxin that he would devote himself wholeheartedly to this matter.

After finishing the affairs of the automobile base, Li Zhongxin went to the place where he was studying the sanitary napkin production line, and specially looked at the research work of the sanitary napkin production line.

What about the sanitary napkin production line! Relatively speaking, it's not very complicated, most of them are made of simple parts, but it's just that! Some of them are cutting-edge machines that are difficult to produce.

But what! Chinese learn very quickly in learning to imitate this kind of thing, and now at this time, there are only two key parts left to complete the sanitary napkin production line, as long as these two parts can be produced in China, then the sanitary napkin assembly line can be manufactured in China.

Li Zhongxin was very satisfied with this matter, and directly told Lin Taiping, who was in charge of the development of the sanitary napkin production line, that the technicians and auxiliary personnel who developed the sanitary napkin production line this time would each receive a bonus of 2,000 yuan, which would be distributed to these people the next day.

Two thousand yuan, for Li Zhongxin now, it is a drizzle, but for these people who have been in charge of researching technology, two thousand yuan is simply an astronomical amount.

Li Zhongxin held a small meeting for these technicians and cartographers, at the meeting, Li Zhongxin gave full affirmation to these technicians who have been silently dedicated, and put forward that in the future, these technicians and scientific researchers, if anyone wants to work in Zhongxin Company, Zhongxin Company will give them much higher welfare than now.

Li Zhongxin said at the meeting, this time! There is a drawing task, need to understand the principle of the machine experts and professional drafters, he wants to make a large drawing in Jiangcheng, he hopes, sanitary napkin production line on this side of the mechanical experts and drafting experts can go to Jiangcheng to help him, if they can't spare time, can help him recommend some manpower, in short! The more such men, the better.

Li Zhongxin said frankly that the design time of this drawing will not be too long, and if there is no big discrepancy, it will be almost completed in half a month.

All the scientific research experts who participated in his drawing design project will definitely not be less than the prize money for the design and development of the sanitary napkin assembly line.

Li Zhongxin and these people have made a decision, and he hopes that more people will be involved in the design of the drawings he said.

It is precisely because of Li Zhongxin's words that within two days of Li Zhongxin's return to Jiangcheng, nearly 20 experts in machinery and drawing have arrived at the headquarters of Jiangcheng Zhongxin Company one after another, waiting for Li Zhongxin's next assignment.

Li Zhongxin is very sad about the hardships of the life of scientific research workers in this era, but it's just that! He could not change such a fact at this time. If he raises the remuneration of scientific research personnel to a certain level on the side of Hei Province, it will affect the overall control of China's leadership, and even more so the country's future development line.

But what! In the future, after the construction of the Zhongxin Scientific Research Building, he will expand the scale of recruiting scientific researchers, and begin to let scientific researchers reflect their due value, instead of letting these people who can make China's long-term development sit on a cold bench in the cold office.

Li Zhongxin remembers that when China first engaged in grape seed processing, it was generally screened, crushed, softened, fried, pre-made cakes, pressed, coarsely filtered, and crude oil.

Use wind or manpower to screen the grape seeds so that there are no impurities such as skin pomace and pomace.

All ripe grape seed seeds are crushed with a double roller crusher to increase the oil yield.

Put the grape seeds into the softening pot, put about 15% soft water, raise the temperature to 65~70C, and keep warm for 40 minutes to soften all the broken grape seeds.

Transfer the softened grape seed seeds to a frying pan for sautéing. The heat must be uniform during operation, so that the material temperature reaches 11oC, the moisture is 8%-10%, and the time is about 2 minutes.

This method took a long time, and after the development of new production processes and methods in China, the machine was sold to countries that needed it.

The general principle of this machine is very simple, the construction investment period is very short, and it will not take much time to build such a plant.

In the later stage, the process solvent extraction method of grape seed oil began to be used as in the production of soybean oil.

As for the supercritical carbon dioxide extraction method, microwave extraction method, water enzymatic method and other processes, which have surpassed the science and technology of this era, Li Zhongxin does not want to do it for the time being, many times, Li Zhongxin cares about such a thing very much, and tries not to do technology beyond this era.

Having said that, Li Zhongxin summoned technical experts and drafting experts in mechanical engineering this time to ask them to improve this plan.

Li Zhongxin and these people put forward two requirements, now at this time, the extraction process has become mature, domestic new soybean oil manufacturers, have begun to use the extraction method to produce soybean oil.

Whether it is the schematic diagram of the machine, or the manufacturing diagram of the machine, it is now ready-made, and he has entrusted Cao Rui to help him get these drawings.

That's it! The scale of domestic new soybean oil manufacturers is very small, and there is no large-scale equipment to extract oil.

Li Zhongxin wants to engage in a lot of grape seeds, and small machines and equipment can no longer achieve such an effect, so he must make the machinery and equipment larger.

Only in this way can the refining of grapeseed oil be completed in the shortest possible time.

Gather these people together this time! Li Zhongxin wanted them to use the equipment of the advanced extraction method in China to deduce large-scale machinery and equipment.

He wanted Masako Mitsui to start making such large-scale machinery and equipment, and in the past few years, he would first engage in large-scale equipment for grape seed oil, and then after a few years, the profits of grape seed oil processing would be less, so he would start to let Masako Mitsui produce soybean oil and various practical oil equipment.

Although Li Zhongxin knows in his heart that subcritical biotechnology n-butane extraction is easier to form industrial-scale production than carbon dioxide extraction.

However, he has not yet achieved a technological breakthrough, and he has not yet had the idea of doing it.

At this time, Li Zhongxin felt that it was enough to extract grape seed oil by extraction, and as long as they could get the drawings as quickly as possible, Masako Mitsui would be able to set up a processing plant in Tokyo in the shortest possible time, and by the time the dried grape seeds and grape skins from Gemino's side arrived in China, they would have almost been able to start production and processing.
