Reborn My 1993

Chapter 260 Vacuum Machine
During this trip to Dongyang, Zhang Yiming and Tan Hongmei purchased more than 500 kilograms of dried red mushrooms in addition to [-] kilograms of drunk dates.

The next day, Lei Feng drove a truck and transported all the mountain goods back to the food factory.

Like the drinking water before, Zhang Heshan still doesn't agree with the big boss's processing of mountain products. After all, the concept in his bones is difficult to change, but it may also be due to the success of the previous mountain spring water sales that Zhang Heshan has more or less no more. Oppose it as firmly as before.

Although the water content of drunk dates is much less than that of fresh dates, because they are soaked in high-strength white wine, there is still a lot of water. What kind of packaging is now very important.

Zhang Yiming's first reaction was vacuum packaging.

But at this time, there is no large-scale vacuum equipment on the market at all, and even plastic bags are not very formal.

After the drunken dates were purchased, they were directly stored in the warehouse. Without the soaking in white wine, the preservation of the drunken dates became very difficult. Zhang Yiming had to find a way to process and seal these drunken dates as soon as possible.

Since such equipment cannot be bought, Zhang Yiming plans to design it himself.

After all, the equipment for vacuuming is not too technically difficult.

When Zhang Heshan came home that day, he went to the warehouse to move the toolbox and a big basket that he hadn’t taken out for a long time. I told my father about this.

"Dad, what are you doing? I haven't seen you tinkering with these things for a long time!"

Since his rebirth, Zhang Yiming's acting skills have become more and more proficient. He even felt that if he couldn't survive in the mall, he might be able to go to the film and television industry with Zhang Yi. Class Dangdang.

"I'm tinkering with something, Xiao Ming, have you heard of vacuum?"

Tan Hongmei just heard Zhang Yiming tell her the general concept of vacuum, but she didn't know it well, so she could only tell Zhang Heshan what Zhang Yiming told her.

Zhang Heshan didn't know anything about the vacuum, so he went to the Xinhua Bookstore to find information about it, but found nothing in the bookstore all afternoon.

"I heard."

"Have you heard? Then tell Dad, what's going on?"

"To put it bluntly, a vacuum is to extract air from a fixed space, so that the gas state in the space is lower than atmospheric pressure."

This concept exists in physics books, but Zhang Yiming simplified the concept a bit.

"Atmospheric pressure?"

Zhang Heshan was a little confused. He only went to the second year of junior high school, and at that time, he basically didn't learn anything in physics classes. In addition, in that special age, students didn't have any interest in studying at all. He felt very unfamiliar with the word atmospheric pressure.

"Dad, for example, a hair dryer. If we point the hair dryer at a plastic bag and blow air, the plastic bag will bulge up. That's because of something, because the plastic bag is filled with air, and the gas state inside is higher than the atmospheric pressure. Vacuum is the opposite, it uses a method to extract the air in the plastic bag, just like we breathe into the plastic bag with our mouth, the effect is the same.”

Zhang Yiming had already prepared in his heart how to explain these things to Zhang Heshan, so it was very smooth and easy to understand.

The reason why he didn't go directly to the manufacturer, but handed over the matter to Zhang Heshan, was because the technical content of this thing is not very high, but if you find a hair dryer manufacturer, you must pay a relatively large amount of money for the design. There is no way to prevent this technology from flowing out of hair dryer manufacturers. Second, he believes in his father’s ability. Although he doesn’t read many books, his father has been interested in these things since he was a child. He believes that with his father’s ability, It must be possible to design a vacuum machine.

Because Zhang Yiming's explanation is very easy to understand, Zhang Heshan immediately understood and mastered the concept of vacuum and the means of realization. After Zhang Yiming entered the house, Zhang Heshan ran to the kitchen and moved the fan used to blow the stove to the outer room On the ground, Qin Fang made the dishes at night because the heat was not enough, so the vegetables were waterlogged.

This night, Zhang Heshan worked in the outhouse by himself until almost dawn.

"Xiao Ming, come out and see if Dad made this right?"

Zhang Yiming got up and opened the door, and saw that his father's eyes were bloodshot, and the black bags under his eyes were scary, but the luster in his eyes was very bright, even a little crazy.

"Dad, you haven't slept all night?"

"Don't worry about it, come and have a look."

Zhang Heshan pulled Zhang Yiming's arm impatiently, and pulled Zhang Yiming to the outhouse. The ground of the outhouse was littered with various tools, glue, raw tape, and wires. Zhang Heshan Picking up the hair dryer, he handed Zhang Yiming a plastic bag and asked Zhang Yiming to point the plastic bag to the blower outlet of the hair dryer.

With a bang, the plastic bag in Zhang Yiming's hand shrank together, almost in the blink of an eye, almost a few tenths of a second.

"Dad, you are so awesome!"

Zhang Yiming's words were sincere, not because Zhang Heshan was his father.

"It's alright this time, I'll be able to deal with the big boss now, okay, I'll pack up, and I'll take the things to the food factory."

Zhang Heshan was very excited, didn't eat, washed his face and went out with a hair dryer.

Looking at his father's back in a hurry, Zhang Yiming couldn't help but shook his head and smiled.

The current father is really different from the father in the previous life!
After Zhang Heshan arrived at the food factory, he handed over the hair dryer in his hand to Tan Hongmei, and in the afternoon, the hair dryer was in the hands of Zhang Yiming.

"Xiao Ming, tell me about you two. If there is anything you can't say directly, you still have to use me as a messenger, which makes my legs thin."

Tan Hongmei complained to Zhang Yiming half-seriously and half-jokingly.

"Haha, now is not the time, Sister Tan will work harder!"

Zhang Yiming took the hair dryer in his hand, and asked Tan Hongmei to send a message to his father, saying that he wanted him to produce a design drawing. Tan Hongmei gave Zhang Yiming a blank look, and then called Zhang Heshan.

Since there is a big brother, it is much more convenient for everyone to connect.

Tan Hongmei asked Zhang Yiming more than once to get him a big brother too, so as not to have to go back and forth to find a public phone booth, but Zhang Yiming refused.

All he wants to do now is keep a low profile, especially in front of his parents.

He is just an ordinary high school student who studies hard and works hard to get into college.

Zhang Heshan was not very good at drawing design drawings, so Zhang Yiming naturally pretended to be an assistant and helped Zhang Heshan draw the design drawings. Then he found a fan factory and began to customize vacuum machines.

Of course, before ordering, he signed a product protection agreement with the fan factory in advance, that is to say, if the fan enters the market, no matter what the reason is, the fan factory must bear certain responsibilities. I really despise Zhang Yiming's vacuum pump, so I didn't think about it at all when signing the agreement, but after three years, the owner of this fan factory will regret it.

He didn't know if he was deceived by lard at the beginning, so he signed that kind of hellish agreement, but at this time, it was already too late to regret it.
